Abstract
According to an embodiment, a solid-state imaging device includes: an imaging element formed on a semiconductor substrate; a first optical system configured to focus an image of a subject on an imaging plane; a second optical system including a microlens array including a plurality of microlenses corresponding to the pixel blocks, and re-focusing the image of the imaging plane onto the pixel blocks corresponding to the respective microlenses; a first filter placed on the second optical system, and including a plurality of first color filters corresponding to the microlenses; and a second filter placed on the imaging element, and including a plurality of second color filters corresponding to the first color filters of the first filter. The first and second filters are designed so that the first and second color filters deviate to a periphery of the imaging area, the deviation becoming larger toward the periphery of the imaging area.
