  • Patent number: 12236832
    Abstract: The disclosure relates to a luma adjustment method and apparatus, a computer device, a storage medium, and a computer program product. The method includes: acquiring a first luma requirement or a second luma requirement; acquiring, based on a current image of a display page, a luma map corresponding to the current image; converting the luma map from a linear space to a logarithmic space when the luma adjustment requirement is the first luma requirement; filtering the luma map to acquire a base layer image and a detail layer image; compressing the base layer image and the detail layer image based on a configuration parameter for merging, to obtain a merged image; converting the merged image from the logarithmic space to the linear space when the luma adjustment requirement is the first luma requirement; and adjusting luma of the display page based on the luma map and the merged image.

  • Publication number: 20240257299
    Abstract: A method for processing text images, an apparatus therefor, a device and a storage medium are provided. The method includes: obtaining an initial text image; extracting luminance and chrominance of the initial text image; obtaining coefficients of chrominance transformation by performing a linear transformation on the chrominance based on the luminance; and obtaining a to-be-displayed text image based on the coefficients of chrominance transformation. Luminance values of the text image are integrated into output chrominance values. There is no lack of data about the luminance values during a display process, thereby avoiding blurring and color distortion problems caused by traditional chroma upsampling algorithm and improving display effect.
