Abstract
An image pickup device that is capable of performing shading correction with sufficient accuracy even if data volume for the shading correction is reduced. The image pickup device includes a plurality of unit pixels arranged in a two-dimensional matrix form. Each of the plurality of unit pixels includes a plurality of first sensitivity pixels having a first sensitivity, and at least one second sensitivity pixel having a second sensitivity different from the first sensitivity. The first and second sensitivity pixels are arranged so that a centroid position of the second sensitivity pixel approximately coincides with the centroid position of the first sensitivity pixels.
