ABSTRACT:
The discriminating method utilizes first to third sensors respectively having spectral sensitivities corresponding to three primary colors and a fourth sensor having a spectral sensitivity that does not overlap the spectral sensitivities corresponding to the three primary colors as sensors constituting an image pickup system, and discriminates a light source type of a photographic light source by using information obtained by the first to fourth sensors. The image forming method corrects image data of an input image using the light source type discriminated by the above light source type discriminating method.
