Image processing method, apparatus and electronic device

Disclosed are an image processing method, apparatus and electronic device, the method comprising: selecting content-associated subpixels in an image to be processed; acquiring an initial color scale value of each selected subpixel in the image to be processed; adding at least one digit to the end of the initial color scale values, and assigning any of preset numerical values to each added digit to obtain a processed color scale value; and replacing the initial color scale value with the corresponding processed color scale value. The technical solution of the present disclosure optimizes image display, and generates finer color transition in the image.
