  • Publication number: 20240221114
    Abstract: The present application relates to the technical field of image processing and discloses a single image super-resolution processing method and system. The method includes: inputting an image to be processed and performing edge direction-based upsampling on the image to obtain a target resolution image; inputting the target resolution image obtained by upsampling into one or more lookup tables to obtain a residual image, wherein the one or more lookup tables hold residual image information; and adding the target resolution image obtained by the upsampling to the residual image to obtain a super-resolution image. This application aims to improve image jaggedness, enhance image definition, and thus improve image quality without increasing too much hardware resources.

  • Patent number: 11461879
    Abstract: An image processing method converts an original image represented in an original color gamut to a target image represented in a target color gamut. The image processing method comprises: A) calculating a set of primary color direction deviations between a set of original primary color directions of the original color gamut and a set of target primary color directions of the target color gamut, wherein each of the set of primary color direction deviations corresponds to a primary color; B) determining, for each pixel in the original image, a corrected color coordinate of the pixel based on a set of offsets of an original color coordinate of the pixel in the original color gamut relative to the set of original primary color directions and the set of primary color direction deviations; and C) mapping, for each pixel in the original image, the corrected color coordinate of the pixel into the target color gamut to generate a target color coordinate of the pixel in the target color gamut.
