Abstract

The invention provides an image color restoration method and related equipment, and the method is applied to a display device, and comprises the steps: receiving screen color gamut RGB data generated by a photographing device; acquiring a shooting environment color temperature when the shooting device shoots an image, a display environment color temperature of the display device and a color coordinate of white in screen color gamut information of the display device; and according to the shooting environment color temperature, the display environment color temperature and color coordinates of white in the screen color gamut information of the display device, performing color adaptation transformation on the screen color gamut RGB data to obtain display environment RGB data. According to the invention, accurate restoration of the image color can be realized.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to an image color restoration method and related equipment. Background technique [0002] People often use a photographing device to capture images, and use a display device to display the captured images. If the color gamut of the image generated by the photographing device is different from the color gamut used by the display device, the display system will not be able to accurately restore the color of the image, resulting in a color difference between the image the user sees from the display device and the image captured in the real scene. In addition, in different light environments, the picture observed by the human eye will show different colors. If the light used to capture the image and display the image is different, the color of the image seen by the user from the display device will also be distorted. SUMMARY OF THE INVENTION [0003] The embo...
