Patent ID: 7317478

Claim:
A solid-state imaging apparatus comprising: a solid-state imaging element having a plurality of pixels for subdividing incident light from a photographic subject into a plurality of color signals so as to image the photographic subject, the solid-state imaging element including two sorts of pixels whose spectral sensitivities are different from each other, the two sorts of pixels for detecting one color among said plurality of color signals; and signal processing means for performing a white balance correcting operation based upon a gain amount corresponding to a sort of a light source with respect to photographed image data outputted from the solid-state image element, said signal processing means including: mixing ratio predicting means operated in such a manner that when there are plural sorts of light sources as to the incident light, a mixing ratio of illumination light emitted from said plural sorts of light sources is predicted for every pixel from photographed image data acquired by said two sorts of pixels having said different spectral sensitivities; and gain amount calculating means for calculating a gain amount used to perform the white balance correcting operation for every pixel in response to said mixing ratio.
