ABSTRACT:
A solid-state image sensor has a plurality of pixels, a read-out circuit and a signal processing section. The plurality of pixels includes a plurality of first pixels, a plurality of second pixels, a plurality of third pixels and a plurality of fourth pixels. The signal processing section includes a color acquisition section, a first judgment section configured to determine whether or not the white data value W in the target pixel block is smaller than a predetermined first set value, and a white color correction section configured to perform correction processing of the white color data value W in the target pixel block based on the following Expression (1) when the judgment result of the first judgment section is NO, and to output the white data value W by itself without performing the correction processing based on the Expression (1) when the judgment result of the first determination section is YES;in-line-formulae description="In-line Formulae" end="lead"?W′=S1C1+S2C2+S3C3  (1)in-line-formulae description="In-line Formulae" end="tail"?where each of S1, S2, and S3is a coefficient that is determined based on a color balance.
