Abstract
There is provided a signal processor including a phase difference detection part configured to acquire a pixel value of one light-shielding pixel having a part of a light-receiving region shielded therein and pixel values of a peripheral pixel row of the light-shielding pixel in a light shielding direction. A corrected pixel value obtained by subjecting the pixel value of the light-shielding pixel to a reduced sensitivity correction is compared with the pixel values of the peripheral pixel row to detect a phase difference of the light-shielding pixel.
