Abstract
A solid state imaging device according to an embodiment includes: an imaging element formed on a semiconductor substrate, and including pixel blocks each having pixels; a main lens forming an image of a subject on an imaging plane; a microlens array including microlenses corresponding to the pixel blocks, the microlens array reducing an image to be formed on the imaging plane by Nf times or less and forming reduced images on the pixel blocks corresponding to the respective microlenses; and an image processing unit enlarging and synthesizing the reduced images formed by the microlenses, the solid state imaging device meeting conditions of an expression MTF(u)≦MTF(u)≦MTF(u×Nf) where u denotes an image spatial frequency, MTF(u) denotes an MTF function of the microlenses, and MTF(u) denotes an MTF function of the main lens.
