Abstract
A chroma adjustment method, an electronic device and a non-transitory computer-readable storage medium are provided. The input color data is converted into preset color data in a preset color space. The preset color data is processed to determine a maximum chroma value among multiple chroma values for each of which the number of corresponding pixels is a peak in a chroma statistical graph, and a maximum luminance value of pixels corresponding to the maximum chroma value is determined. A chroma adjustment coefficient is obtained, according to the maximum chroma value, the maximum luminance value and a chroma mapping curve. The input color data is adjusted based on the chroma adjustment coefficient, to obtain output color data.
