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.
