Abstract: A method of eliminating a color cast of image in photographic device includes: obtaining a color cast image; determining a color temperature of the color cast image; analyzing a brightness ratio among a first primary color, a second primary color, and a third primary color of the color cast image; choosing one parameter group from a plurality of color cast calibration parameter groups according to the color temperature; calibrating the brightness ratio among the first primary color, the second primary color, and the third primary color of the color cast image via the chosen color cast calibration parameter group.
