The embodiment of the invention provides a method and apparatus for reducing a saturation or pocking mark phenomenon existing in an image, and relates to the field of display technology to solve the existing saturation phenomenon and the pocking mark phenomenon generated after pixel points in an image with uneven colors are corrected. The method comprises the following steps: determining an unevenness degree coefficient of a to-be-corrected pixel point in a device screen according to the unevenness degree coefficient and coordinates of a vertex of a target subarea where the to-be-corrected pixel point in an image subjected to color evenness correction is located in the device screen, and the coordinates of the to-be-corrected pixel point in the device screen, and then performing weighted summation on color values of the to-be-corrected pixel point in the images before and after the color evenness correction by using the unevenness degree coefficient of the to-be-corrected pixel point and a color change degree coefficient of a color value of the to-be-corrected pixel point in the image subjected to the color evenness correction after being displayed in the device screen, so as to obtain an output color value of the to-be-corrected pixel point.
