Abstract
Disclosed are a chroma compensation method and apparatus, a display device and a storage medium. The chroma compensation method includes: acquiring an initial color of a display sub-pixel in a target pixel unit under a target luminance, and a target color of the target pixel unit under the target luminance, the target pixel unit including: at least two display sub-pixels of different light colors; acquiring a complementary color gain of each of the display sub-pixels under the target luminance based on the target color and the initial color of each of the display sub-pixels; and compensating for chrominance of the target pixel unit based on the complementary color gain of each of the display sub-pixels under the target luminance.
