ABSTRACT:
In an image pick-up apparatus which has an image pick-up device having a main pixel of high sensitivity and a sub-pixel of low sensitivity in one pixel, gain values for white balance adjustment are calculated in association with each of the main pixel and the sub-pixel, or gain values for white balance adjustment are stored in advance for each of the main pixel and the sub-pixel. White balance adjustment is separately performed on the main pixel and the sub-pixel using the gain values for white balance adjustment, and image signals from both of them are synthesized to obtain one image. Thus, proper white balance control can be allowed to obtain an picked-up image having excellent color reproducibility.
