An apparatus configured to correct a captured image using a gloss component based on a virtual light source sets a light-source color of the virtual light source. The apparatus generates the gloss component on a subject in the captured image using the light-source color corrected according to a color tone of the captured image. The apparatus corrects the captured image by adding the generated gloss component to the captured image.

With the method, the skin color adjustment can be flexibly and accurately adapted to various skin color conditions.

An image display device includes a display unit configured to display a display image and to use a color information target value as a color information value of a display color, the display color being a color of the displayed image; and a first image correction unit configured, in a case where the color information value of the display color of the display image obtained by capturing the display image displayed by the display unit is different from the color information target value, to correct the color information value of the display color of the displayed image displayed by the display unit, so that the color information value of the display color of the display image obtained by capturing the display image displayed by the display unit becomes the color information target value.

This application provides a control display method and an electronic device. The method includes: determining a display position of a control on a background picture; and then determining a display scene of the background picture at the display position of the control, where the display scene of the background picture at the display position of the control is determined based on display parameters of the background picture at the display position of the control; determining display parameters of the control based on the display scene of the background picture at the display position of the control, so that a contrast between the background picture displayed at the display position of the control and the control displayed based on the display parameters meets a first preset condition; and displaying the control based on the determined display parameters of the control. This application is applicable to control display of the electronic device.

A processor device includes: an image acquisition unit that acquires a static image of an object to be observed; an embedding unit that embeds a correction profile, which is created by a creation unit according to tone change-related information about a change in the tone of the static image, in the static image; and an output unit that outputs the static image, in which the correction profile is embedded, to the outside. In an image display device, a static image in which a correction profile is embedded is received and correction is performed on the static image by using the correction profile. Then, the static image on which the subjected has been performed is displayed on a display.

An image correction device includes a reception unit, a detection unit and a correction unit. The reception unit receives a first-image and a second-image, which are obtained by a first-imaging device and a second-imaging device, and an imaging condition that is at least one piece of information on an imaging date and time or information on an imaging location corresponding to each of the first-image and the second-image. The detection unit detects the same scene between images indicated by the first-image and the second-image based on the imaging conditions corresponding to each of the first-image and the second-image. The correction unit extracts, from each of the images indicated by the first-image and the second-image corresponding to the same scene, a common subject which is common between the images, and performs, on the corresponding image, color correction of making colors of the extracted common subject similar to each other.

The present disclosure relates to methods and devices for display processing. The device can receive a first image including a plurality of first pixels. Each of the first pixels can include a first red, green, blue (RGB) color value. The device can also determine an RGB adjustment value based on a lens correction value. Additionally, the device can determine a second RGB color value for each first pixel based on the determined RGB adjustment value. The device can also generate a second image including a plurality of second pixels, where each of the second pixels includes a determined second RGB color value. Moreover, the device can separate at least one of a red color value, green color value, or blue color value of the RGB color value and adjust at least one of a red color value or a blue color value based on the lens correction value.

An electronic device and a method for controlling the electronic device are provided. The electronic device includes a storage; a display; a communication interface configured to communicate with an external device to receive, from the external device, a video signal including a plurality of frames at a second transmission speed that is faster than a first transmission speed; and a processor configured to: control the communication interface to receive the plurality of frames transmitted at the second transmission speed and store the plurality of frames in the storage, identify features of a second frame among the plurality of frames to be played back after a first frame among the plurality of frames, and control the display to display the first frame based on the identified features of the second frame.

Systems and methods are disclosed for image signal processing. For example, methods may include accessing an image from an image sensor; detecting an object area on the image; classifying the object area on the image; applying a filter to an object area of the image to obtain a low-frequency component image and a high-frequency component image; determining a first enhanced image based on a weighted sum of the low-frequency component image and the high-frequency component image, where the high-frequency component image is weighted more than the low-frequency component image; determining a second enhanced image based on the first enhanced image and a tone mapping; and storing, displaying, or transmitting an output image based on the second enhanced image.

The present application provides a white balance processing method and apparatus. The method comprises: recognizing a portrait region in an image; calculating a target white balance gain value according to the area occupied by the portrait region in the image; and performing white balance processing on the image according to the target white balance gain value. The present application resolves the problems of poor user experience due to inaccurate image color restoration caused by a small area proportion of a human face region in an image during white balance adjustment according to the white balance gain value determined according to the area occupied by the human face in the case of a long photography distance.
