1. A luminance and color compensation method, adapted to a self-luminous display panel, comprising:
calculating a plurality of compensation values of a plurality of display pixels of a plurality of setting grayscale values based on at least one selected color;
recording the compensation values to obtain look-up information;
receiving a plurality of image grayscale values of a display image, and obtaining a plurality of selected compensation values respectively corresponding to the display pixels according to the look-up information based on the image grayscale values; and
respectively compensating display luminance of the display pixels according to the selected compensation values,
wherein the compensation values are calculated according to a color complementary principle.
