An information processing apparatus includes a processor configured to acquire a manuscript image and an additional image added to the manuscript image, and reduce an image area other than a blank area in the manuscript image so that the additional image fits in the blank area of the manuscript image.

Provided are an image layout size calculation apparatus, an image layout size calculation method, and an image layout size calculation program which are capable of outputting an image with a small blurriness degree. A blurriness value is calculated for each image area, and the smallest blurriness value is decided (step S24). Resolution of a printer that prints the image is read (step S25). A layout size in which the blurriness value is equal to or smaller than a second threshold value is calculated based on the number of pixels of the image, the decided blurriness value, and the resolution of the printer (step S26). By printing the image having a size equal to or smaller than the calculated layout size, the blurriness degree of the printed image is reduced.

An image capturing device in the present embodiment has a configuration that is provided with an image splitting unit 21 and an edge extracting unit 22 that acquire the edge component for each block image that has been divided from an image captured by an image sensor 10, a resolution controlling unit 23 that writes each block image into a frame memory 30 with a resolution in accordance with the amount of its edge component, an image enlarging unit 24 that reads out at least one block image that corresponds to a selected region from the frame memory 30 and enlarges the block image with a magnification in accordance with the size of the selected region, and an enlarged output unit 45 that outputs the enlarged block image that corresponds to the selected region that is supplied from the image enlarging unit 24.

A reading portion generates an original image including an image of a document sheet. A first document sheet end detection portion, in a case where the thickness of the document sheet is equal to or greater than a threshold value, identifies a peripheral edge shape of the document sheet by detecting a shadow portion that occurs at a peripheral edge portion of the document sheet in the original image. A second document end detection portion, in a case where the thickness of the document sheet is less than a threshold value, identifies the peripheral edge shape based on a specification by the user. A document sheet size determination portion determines a size of the document sheet according to a result of shape identification by the first document sheet end detection portion or a result of shape identification by the second document sheet end detection portion.

An information processing device executes: acquiring a scanned image of a document and a protective sheet that protects the document, the scanned image being obtained by imaging the document and the protective sheet while being conveyed at the same time; acquiring a first length that is a conveying direction length of a predetermined portion of the protective sheet; acquiring a second length that is a conveying direction length of the predetermined portion in the scanned image; and estimating a ratio between a document length, which is a conveying direction length of the document, and a document image length, which is a conveying direction length of the document in the scanned image, based on the first length and the second length.

An image processing apparatus includes: an input device that inputs a document image; and a controller, wherein the controller removes a streak from the image by a first method, removes a streak from the image by a second method that differs from the first method, and executes crop processing on the image from which the streaks have been removed.

A method of controlling an information processing apparatus includes displaying an edit screen including an obtained image and a print range frame based on obtained print setting information, accepting an edit operation of arrangement of the image in the edit screen, generating image data based on an edited image, and transmitting the generated image data and the print setting information to the image forming apparatus as a print job. Where the image has been edited such that there is a region where the image is not arranged in the print range frame, combining processing in which a predetermined image is added in the region is performed and whereby image data including the image and predetermined image is generated, and where the image has been edited such that there is no region where the image is not arranged in the print range frame, the combining processing is not performed.
