Abstract:
According to the present invention, it is possible, by using the first and second light source loci, to tone down the influence of the object color of the color information in the image and detect the light source based on the color information having the influence of the object color toned down so as to detect the light source accurately. It is thereby possible to reduce the color failure when controlling the white balance.
