(78) In the analysis of the user-selected image 102A shown in FIG. 4, one or more types of attributes such as an object determination result, the degree of blurring, the degree of camera-shake, the degree of brightness, a color, face recognition of a person, and the number of persons are applied, and attribute information is assigned for each attribute.

(79) FIG. 5 is a schematic diagram showing an example of analysis results of selected images. An arbitrary character string is written in a file name shown in FIG. 5. FIG. 5 illustrates the object determination result, the degree of blurring/camera-shake, the degree of brightness, the color, and the person, as the types of attributes. The degree of blurring/camera-shake shown in FIG. 5 indicates the degree of blurring and the degree of camera-shake, in other words, the degree of focus.

(80) As the object determination result, objects may be classified into a person, a landscape, an object type, and the like. FIG. 5 illustrates food, a landscape, and a person as examples of the types of objects. The object determination may be performed using a tagging technique for an image.

(81) As the degree of blurring/camera-shake, a blurring/camera-shake evaluation value represented by a numerical value in a range of 0 to 100 may be applied. In a case where the blurring/camera-shake evaluation value is relatively large, it represents a good image with a relatively small degree of blurring.

(82) The analysis result shown in FIG. 5 indicates that the blurring/camera-shake evaluation values of four user-selected images 102A among five user-selected images 102A are 80 or greater, and therefore, a selection standard with which the user selects images with a blurring/camera-shake evaluation value of 80 or greater may be estimated. In other words, the blurring/camera-shake evaluation value may be estimated as the user selection standard in a case where the user selection ratio satisfies 80% or greater.

(83) As the degree of brightness, a brightness evaluation value represented by a numerical value in a range of 0 to 100 may be applied. In a case where the brightness evaluation value is relatively large, it represents a good image with a relatively high brightness. As the degree of brightness, the lightness in the Munsell color system may be applied.

(84) The analysis result shown in FIG. 5 indicates that brightness evaluation values of three user-selected images 102A among five user-selected images 102A are 80 or greater, and therefore, a user selection standard with which the user selects images with a brightness evaluation value of 80 or greater may be estimated. In other words, the brightness evaluation value may be estimated as the user selection standard in a case where the user selection ratio satisfies 60% or greater.

(85) As the color, a color evaluation value represented by a numerical value in a range of 0 to 100 may be applied. In a case where the color evaluation value is relatively large, it represents a good image with a relatively vivid color. As the brightness, the saturation in the Munsell color system may be applied.

(86) The analysis result shown in FIG. 5 indicates that color evaluation values of three user-selected images 102A among five user-selected images 102A are 80 or greater, and therefore, a user selection standard with which the user selects images with a color evaluation value of 80 or greater may be estimated. In other words, the color evaluation value may be estimated as the user selection standard in a case where the user selection ratio satisfies 60% or greater.

(87) The person indicates whether or not a specific person is included. The user-selected image 102A represented by a file name 0002.xxx shown in FIG. 5 represents that a person A and a person B are included. The user-selected image 102A represented by a file name 0004.xxx represents that the person A is included.

(88) In the analysis result shown in FIG. 5, three user-selected images 102A having a file name 0001.xxx, a file name 0003.xxx, and a file name 0005.xxx among the five user-selected images 102A are assigned food as attribute information. On the basis of this analysis result, a user selection standard with which the user wants to select an image including food may be estimated. In other words, the object determination result may be estimated as the user selection standard in a case where the user selection ratio satisfies 60% or greater.

(89) Further, two user-selected images 102A having the file name 0002.xxx and the file name 0004.xxx, among the five user-selected images 102A, are assigned the person A as attribute information. On the basis of the analysis result, a user selection standard with which the user wants to select an image including the person A may be estimated.

(90) In other words, the person information included in the person determination result may be estimated as the user selection standard in a case where the user selection ratio satisfies 40% or more. As for the person determination result, the user selection standard may be estimated on the basis of a ratio of a user-selected person to a total number of the user-selected images 102A including persons among the user-selected images 102A.

(91) For example, the user-selected images 102A including the person A among the five user-selected images 102A shown in FIG. 5 are the user-selected images 102A having the file name 0002.xxx and the file name 0004.xxx.

(92) Since the person A is assigned to both the user-selected images 102A having the file name 0002.xxx and the file name 0004.xxx, the ratio of the user-selected person for the person A is 100%. For example, in a case where a threshold value for estimating the user selection standard is 80% or greater, a user selection standard with which the user wants to select an image including the person A may be estimated.

(93) That is, in the analysis process of the user-selected image 102A, attribute information is assigned to one or more types of attributes for each user-selected image 102A, the user selection standard according to the user's preference or the like is estimated on the basis of the user selection ratio obtained by dividing the number of user-selected images 102A having the same attribute information by the total number of the user-selected images 102A.

(94) In the example shown in FIG. 5, an example in which the user selection standard is estimated using the attribute information in which the user selection ratio is equal to or greater than a predetermined threshold value is illustrated, but the threshold value for the user selection ratio may be arbitrarily prescribed according to the number of user-selected images or the like. The threshold value for the user selection ratio may be a preset fixed value or a setting value manually set by the user.

(95) Note that the types of attributes shown in FIG. 5 are examples, and the types of attributes applied to the selected images are not limited to the examples of FIG. 5. Further, the number of types of attributes may be one or more. For example, the attributes that are analyzed by the analysis section 56 shown in FIG. 2 and are assigned to the non-selected images may be at least one of the type of an object, the degree of focus representing the degree of blurring of an image and the degree of camera-shake, the degree of brightness, a color, or the presence or absence of the person.

(96) Further, the user selection ratio based on the user-selected images 102A shown in FIG. 5 is an example of a first user selection ratio. The user selection standard based on the first user selection ratio is an example of a first user selection standard.

(97) Specific Example of Selection Process in Automatic Selection Step

(98) In the automatic selection step S18 shown in FIG. 4, the non-selected images 102B in the candidate images are analyzed, and an auto-selected image is selected from the non-selected images 102B using the user selection standard. For the analysis of the non-selected images 102B, the same process as the analysis process of the user-selected images 102A in the selected-image analysis step may be applied.

(99) FIG. 6 is a schematic diagram showing an example of analysis results of non-selected images. In the analysis results of the non-selected images 102B shown in FIG. 6, attribute information is assigned to the non-selected images 102B with respect to the same types of attributes as the analysis results of the user-selected images 102A shown in FIG. 5.

(100) For the non-selected images 102B, a standard score is calculated for each non-selected image 102B using the attribute information assigned to each non-selected images 102B. The standard score shown in FIG. 6 is calculated by adding up numerical values obtained by scoring the number of persons, with a score per person being 100, with respect to a sum of a blurring/camera-shake evaluation value, a brightness evaluation value, and a color evaluation value.

(101) Then, an adjusted score is calculated by adjusting the standard score on the basis of the user selection standard. In a case where the user selection standard with which the user wants to select an image including food in an object is estimated, a non-selected image 102B including food in the object is assigned an adjustment value by a positive weight to calculate the adjusted score. A prescribed number of auto-selected images are selected in a descending order of the adjusted scores.

(102) FIG. 7 is a diagram illustrating adjusted scores. Since an analysis result that the object includes food is obtained for the non-selected image 102B having a file name 0011.xxx, the adjusted score is calculated by applying a positive adjustment value +300 to the standard score shown in FIG. 6.

(103) Further, in a case where the selection standard with which the user wants to select an image including a person is estimated, the non-selected image 102B including the person in the object is assigned a positive adjustment value by a positive weight, so that the adjusted score obtained by adjusting the standard score shown in FIG. 6 is calculated.

(104) FIG. 8 is a diagram illustrating another example of adjusted scores. Since in either the non-selected images 102B having the file name 0010.xxx or the non-selected image 102B having the file name 0013.xxx, an analysis result in which the person A is included in the object is obtained, a positive adjustment value +300 is applied with respect to the standard score shown in FIG. 6 to calculate an adjusted score.

(105) In this way, the adjusted score obtained by adjusting the standard score calculated on the basis of the analysis result of the non-selected image 102B is calculated using the adjustment value as the weight corresponding to the user selection standard, and the auto-selected images are selected in a descending order of the adjusted scores.

(106) In the present embodiment, the adjustment value adjusted by a user determination standard based on a plurality of attributes such as an object determination result and a person is set to the same value, but the present disclosure is not limited thereto. Different adjustment values may be set for respective attributes.

(107) For example, the adjustment value adjusted using the user determination standard based on attributes such as the degree of blurring/camera-shake, the degree of brightness, and the color may be a smaller value, compared with the adjustment value are adjusted using the user determination standard based on the object determination result, the person, and the like.

(108) Specific Example of Automatic Layout

(109) In a case where a plurality of images selected from the candidate images 102 as images to be used for the photo album are laid out on each page of the photo album, the user-selected images 102A may be preferentially laid out with respect to the auto-selected images.

(110) For example, in laying out the user-selected images 102A and the auto-selected images on each page of the photo album, the user-selected images 102A may have a layout larger than that the auto-selected images, or the user-selected images 102A may be laid out on a page having a smaller page number those that of the auto-selected images.

Operational Effects of the First Embodiment

(111) According to the image processing apparatus and the image processing method according to the first embodiment, it is possible to obtain the following operational effects.

(112) [1]

(113) The user-selected images 102A selected by the user are analyzed, and the user selection standard is estimated. The automatic selection of the non-selected images 102B is performed on the basis of the estimated user selection standard. Thus, it is possible to perform an automatic layout of a photo album using the user-selected images and the auto-selected images.

(114) [2]

(115) A standard score based on attribute information is calculated for each non-selected image 102B. The standard score is adjusted using an adjustment value representing a weight based on the user selection standard to calculate an adjusted score for each non-selected image 102B. Thus, it is possible to select the auto-selected images to be used for the photo album in a descending order of the adjusted scores.

Second Embodiment

(116) Overall configuration of image processing apparatus Next, an image processing apparatus according to a second embodiment will be described. In the following description, differences from the image processing apparatus 10 according to the first embodiment will be mainly described. An overall configuration of the image processing apparatus according to the second embodiment will be described with reference to FIG. 2.

(117) In the image processing apparatus according to the second embodiment, a user manually selects a user-selected image that the user does not want to include in a photo album, a user selection standard in which a user's preference or the like that the user does not want to include in the photo album is reflected is estimated on the basis of the analysis result of the user-selected image, and an image that the user does not want to include in the photo album from the non-selected images is excluded from the auto-selected images.

(118) In other words, in selecting the auto-selected images from the non-selected images, a non-selected image estimated as the image that the user does not want to include in the photo album is excluded, so that the auto-selected images to be used for the photo album are selected.

(119) The user selection information acquisition section 54 acquires user selection information of the user-selected image manually selected by the user from the viewpoint of the image that the user does not want to include in the photo album. The analysis section 56 analyzes the user-selected image, and the attribute information assigning section 58 assigns attribute information for each type of attribute for each user image.

(120) The standard estimation section 60 estimates a user selection standard of the image that the user does not want to include in the photo album, on the basis of a ratio of the user-selected images having the same attribute information to a total number of user-selected images. In other words, the standard estimation section 60 estimates the user selection standard as a negative weight.

(121) The automatic selection section 62 selectively excludes, from the non-selected images, an image estimated as the image that the user does not want to include in the photo album on the basis of the user selection standard, and selects the non-selected images in which the exclusion target image is excluded as auto-selected images.

(122) The layout section 64 performs an automatic layout of the photo album using the user-selected images and the auto-selected images. Note that the candidate images are shown in FIG. 9 using a standard numeral 202. The user-selected images are shown in FIG. 9 using a standard numeral 202A. The non-selected images are shown in FIG. 9 using a standard numeral 202B.

(123) Procedure of Image Processing Method

(124) An image processing method according to the second embodiment will be described with reference to FIG. 3. In the user selection information acquisition step S14, the user selection information acquisition section 54 acquires user selection information for the user-selected images manually selected by the user from the viewpoint of the image that the user does not want to include in the photo album.

(125) In the user-selected image analysis step S16, the user-selected images are analyzed, and the user selection standard of the image that the user does not want to include in the photo album is estimated on the basis of the ratio of the user-selected images having the same attribute information to the total number of the user-selected images.

(126) In the automatic selection step S18, an image estimated as the image that the user does not want to include in the photo album is selectively excluded from the non-selected images on the basis of the user selection standard, and the non-selected images in which the exclusion target image is excluded are selected as the auto-selected images.

(127) In the layout step S20, an automatic layout of the photo album is performed using the user-selected images and the auto-selected images.

(128) Configuration Example of Selection Screen

(129) FIG. 9 is a schematic diagram of a selection screen applied to the image processing apparatus according to the second embodiment. On a selection screen 200, negative select symbols 204 indicating the user's selection are superimposed with the user-selected images 202A.

(130) In a case where the user operates a select button 206, the user's selection is confirmed for the image that the user does not want to include in the photo album. On the selection screen 200, the user may operate a scroll bar 208 to sequentially display all the candidate images 202 on the selection screen 200.

(131) The user-selected images 202A shown in FIG. 9 are examples of second user-selected images selected by the user from the candidate images as images that are not to be used for the photo album. The user selection information corresponding to the user-selected images 202A shown in FIG. 9 is an example of second user selection information. A user selection ratio based on the user-selected images 202A shown in FIG. 9 is an example of a second user selection ratio. The user selection standard estimated on the basis of the user-selected images 202A shown in FIG. 9 is an example of a second user selection standard.

(132) Specific Example of Analysis Process in Selected-Image Analysis Step

(133) FIG. 10 is a schematic diagram showing an example of analysis results of selected images. In the analysis result of the selected images in the second embodiment, similar to the first embodiment, object determination, the degree of blurring/camera-shake, the degree of brightness, a color, face recognition of a person, and the number of persons are applied as attributes.

(134) In the analysis result shown in FIG. 10, three user-selected images 202A in which an object includes a landscape, among five user-selected images 202A, are selected. This makes it possible to estimate a user selection standard with which the user does not want to include the image in which the object includes the landscape in the photo album. In other words, the object determination result may be estimated as the user selection standard in a case where the user selection ratio satisfies 60% or greater.

(135) Further, two user-selected images 202A in which the object includes the person C are selected, among the five user-selected images 202A. This makes it possible to estimate a user selection standard with which the user does not want to include an image in which the object includes the person C in the photo album.

(136) In other words, the person determination result may be estimated as the user selection standard in a case where the user selection ratio satisfies 40% or greater. Further, with respect to the person determination result, similar to the first embodiment, the user selection standard may be estimated on the basis of a ratio of a user-selected person to a total number of user-selected images 202A including persons, among the user-selected images 202A.

(137) Further, without using the object determination result, the user selection standard may be estimated in a case where the user selection ratio to the non-selected images is equal to or greater than a predetermined threshold value, on the basis of the attribute information such as the degree of blurring/camera-shake, the degree of brightness, the color, and the like.

(138) Specific Example of Selection Process in Automatic Selection Step

(139) FIG. 11 is a schematic diagram showing an example of analysis results of non-selected images. In the analysis of the non-selected images, attribute information is assigned to the non-selected images 202B for the same type of attribute as in the user-selected images 202A, similar to the first embodiment. Further, similar to the first embodiment, the standard score is calculated for each of the non-selected images 202B using the attribute information. Note that illustration of the standard score of the non-selected images 202B is omitted.

(140) In the automatic selection of the non-selected images 202B, a negative adjustment value is calculated as a negative weight on the basis of the user selection standard with which the user does not want to include a certain image in the photo album, and the standard score is adjusted using the negative adjustment value to calculate an adjusted score. A prescribed number of auto-selected images may be selected in a descending order of the adjusted scores.

(141) FIG. 12 is a diagram illustrating adjusted scores. In a case where a user selection standard with which the user does not want to include an image in which an object includes food in the photo album is estimated, a non-selected image 202B having a file name 0011.xxx is assigned an adjustment value −300 as a negative weight to calculate an adjusted score.

(142) FIG. 13 is a diagram illustrating another example of adjusted scores. In a case where a user selection standard with which the user does not want to include an image in which an object includes a person A in the photo album is estimated, a non-selected image 202B having a file name 0010.xxx and a non-selected image 202B having a file name 0013.xxx are assigned an adjustment value −300 as a negative weight to calculate adjusted scores.

(143) That is, the adjusted score is calculated by applying a negative weight to the standard score for each of the non-selected images 202B on the basis of the user selection standards with which the user does not want to include a certain image in the photo album. A prescribed number of auto-selected images may be selected from the non-selected images 202B in a descending order of the adjusted scores calculated for the respective non-selected images 202B.

Operational Effects of Second Embodiment

(144) According to the image processing apparatus and the image processing method of the second embodiment, the following operational effects may be obtained.

(145) [1]

(146) The user-selected images 202A manually selected by the user as images that the user does not want to include in the photo album are analyzed, and the user selection standard of the images that the user does not want to include in the photo album are estimated. The images estimated on the basis of the estimated user selection standard are excluded from the non-selected images 202B, so that the auto-selected images are selected from the non-selected images 202B. Thus, it is possible to perform an automatic layout of a photo album using the user-selected images and the auto-selected images.

(147) [2]

(148) The standard scores of the non-selected images 202B are calculated on the basis of the attribute information. The standard score is adjusted using a negative weight based on the user selection standard with which the user does not want to include an image in the photo album to calculate the adjusted score. Thus, it is possible to automatically select images to be used for the photo album in a descending order of the adjusted scores.

Third Embodiment

(149) Overall Configuration of Image Processing Apparatus

(150) Next, an image processing apparatus according to a third embodiment will be described. In the following description, differences from the image processing apparatus 10 according to the first embodiment will be mainly described. An overall configuration of the image processing apparatus according to the second embodiment will be described with reference to FIG. 2.

(151) The image processing apparatus according to the third embodiment retains display non-selected image information that is information of display non-selected images displayed on a selection screen, among non-selected images that are not selected by a user in selecting user-selected images, estimates user display non-selection standard using the display non-selected image information, and reinforces estimation of a user selection standard.

(152) The user selection information acquisition section 54 shown in FIG. 2 acquires user selection information, and acquires display non-selected image information. Examples of the display non-selected image information include a file name of a display non-selected image, a positional relationship with a user-selected image on a selection screen, a display period on the selection screen, and the like.

(153) The standard estimation section 60 estimates a user display non-selection standard indicating a user's intention of non-selection from the display non-selected image information. Using the estimated user display non-selection standard, the user's intention of non-selecting a display non-selected image is considered, and thus, the estimation of the user selection standard is reinforced.

(154) Procedure of Image Processing Method

(155) In the user selection information acquisition step S14 shown in FIG. 3, the user selection information is acquired, and the display non-selected image information is acquired. In the user-selected image analysis step S16, the non-display selection information regarding the display non-selected images is acquired, the user display non-selection standard indicating the user's intention of non-selection is estimated on the basis of the analysis result of the display non-selected images, the user's intention of non-selecting the display non-selected images is considered using the estimated user display non-selection standard, and the estimation of the user selection standard is reinforced.

(156) Configuration Example of Selection Screen

(157) FIG. 14 is a schematic diagram of a selection screen applied to the image processing apparatus according to the third embodiment. A non-display area 300A is an area in which non-display candidate images 302C that are not to be displayed on a selection screen 300 are disposed, and represents an area that may be displayed on the selection screen 300 in a case where a scroll bar 308 is operated. The non-display candidate images 302C may be selected as the user-selected images 302A in a case of being displayed on the selection screen 300. Standard numeral 302 indicates a candidate image. Standard numeral 302B indicates a display non-selected image. Standard numeral 304 indicates a select symbol. Standard numeral 306 indicates a select button.

(158) Preferences of Users Estimated from Display Non-Selected Images

(159) FIG. 15 is a diagram illustrating a user's preference or the like estimated from display non-selected images. FIG. 15 illustrates, as non-selected image information, a display period on the selection screen 300, a positional relationship with the user-selected image 302A on the selection screen 300, and the degree of similarity to the user-selected image 302A.

(160) As for the positional relationship with the user-selected image 302A on the selection screen 300, a distance therebetween may be applied using a numerical value such as the number of pixels. As for the degree of similarity to the user-selected image 302A, a numerical value such as a ratio may be applied.

(161) Further, FIG. 15 shows an estimation result of a user's intention of non-selecting the display non-selected images 302B. For example, the display non-selected image 302B having a relatively short display period on the selection screen 300 is not nearly visually recognized by, for example, passing a user's visual range in scrolling the selection screen 300 in the course of user's search for the user-selected image 302A, and thus, may be estimated as an image for which there is no intention of non-selection.

(162) On the other hand, the display non-selected image 302B having a relatively long display period on the selection screen 300, a relatively close positional relationship with the user-selected image 302A on the selection screen 300, and a relatively high degree of similarity to the user-selected image 302A may be estimated as an image that is visually recognized by the user but is not selected. That is, it may be estimated as an image that the user does not want to select.

(163) The display non-selected image 302B having a relatively long display period on the selection screen 300, a relatively close positional relationship with the user-selected image 302A on the selection screen 300, and a relatively high degree of similarity may be estimated as an image that is visually recognized by the user but is suspended in selection due to similarity to the user-selected image 302A.

(164) As shown in FIG. 15, a negative adjustment value for adjusting the standard score is assigned to the estimation result of the user's non-selection intention in the display non-selected image 302B, and an adjusted score obtained by adjusting the standard score calculated for each display non-selected image 302B using the adjustment value may be calculated. The negative adjustment value based on the estimation result of the user's non-selection intention is a negative weight with respect to the standard score.

(165) In a case where the weight based on the user selection standard is a negative weight, the weight based on the user display non-selection standard is a positive weight. That is, in a case where the weight based on the user selection standard is any one of the positive weight or the negative weight, the weight based on the user display non-selection standard is the other of the positive weight or the negative weight.

(166) In the present embodiment, as for the display non-selected image 302B, the user display non-selection standard is estimated on the basis of at least one of the display period, the display positional relationship with the selection image, or the degree of similarity, and the adjustment value is set on the basis of the estimated user display non-selection standard, the present disclosure is not limited thereto.

(167) The display non-selected image may be determined as the user-selected image 202A (second user-selected image) of the second embodiment, and similar to the second embodiment, a ratio of the display non-selected images 302B for each attribute to a total number of the display non-selected images 302B is determined as a user selection ratio (second user selection ratio), and a user selection standard (second user selection standard) indicating an image that is not to be used for the photo album may be estimated on the basis of the ratio of the display non-selected images 302B.

(168) Further, an image that satisfies a predetermined condition, among the display non-selected images 302B, for example, only an image that the user does not want to select in FIG. 15 may be determined as the user-selected image of the second embodiment (second user-selected image), and the similar processes as in the second embodiment may be performed.

(169) Specific Example of Selection Process in Automatic Selection Step

(170) FIG. 16 is a diagram showing an example of standard scores. Calculation of the standard score for each display non-selected image 302B shown in the figure is the same as in the first and second embodiments. Thus, description thereof will not be repeated.

(171) FIG. 17 is a diagram illustrating adjusted scores. The adjusted scores shown in FIG. 17 are calculated by considering the adjustment values shown in FIG. 15 with respect to the adjusted scores shown in FIG. 7. The display non-selected image 302B having a file name 0011.xxx is assigned an adjustment value +300 corresponding to a user selection standard with which the user wants to select an image including food in an object.

(172) On the other hand, the display non-selected image 302B having the file name 0011.xxx is assigned an adjustment value −300 corresponding to a user's non-selection intention. Adjusted scores are calculated by performing adjustment using the adjustment values for the standard scores.

Operational Effects of Third Embodiment

(173) According to the image processing apparatus and the image processing method of the third embodiment, the following operational effects may be obtained.

(174) [1]

(175) The user's non-selection intention is estimated from the display non-selected images 302B that is displayed on the selection screen 300 but is not to be selected by the user. Thus, in a case where the auto-selected images are selected from the non-selected images, the user's non-selection intention for each non-selected image may be taken into consideration.

(176) [2]

(177) The display non-selected image 302B is assigned an adjustment value as a negative weight corresponding to the user's non-selection intention, and a corrected score is calculated by correcting the standard score using the adjustment value. Thus, in a case where a prescribed number of auto-selected images are selected in a descending order of the corrected scores, the user's non-selection intention for each display non-selected image 302B may be taken into consideration.
