Abstract
There are photographing scenes which are difficult, for a conventional image pickup apparatus having a solid state image pickup device with primary color filters, to correctly judge whether an illumination light source is the sun or a fluorescent lamp. The solid image pickup device of an image pickup apparatus uses two types of red or green pixels having different spectral sensitivities. The type of a light source can be judged by using signals from the two types of the pixels.
