An image compensation method. A color space conversion operation is implemented in a pixel of a source image to convert first image signals corresponding to the pixel to second image signals corresponding to a color space plane. The color space plane comprises a skin color axis comprising a first skin color compensation region and a second skin color compensation region at both sides of the skin color axis. Mathematical operations are implemented in the second image signals to determine where the pixel is located. When the pixel resides in the first skin color compensation region or the second skin color compensation, a compensation operation is implemented in the second image signals. Thus, the color of the pixel approaches the skin color.
