Solid state imaging device

Abstract

In a solid state imaging device, sensitivity deterioration (shading) of the periphery of the imaging region is planned to be improved. An on-chip micro lens 28 corresponding to each sensor portion 23 in an imaging region 42 is comprised and the center of the reduction magnification of the exit pupil correction which is performed for the on-chip micro lens 28 is set to a position O deviated from the center of the imaging region 42.

Description

technical field [0001] The present invention relates to a solid-state imaging device. Background technique [0002] Heretofore, in imaging cameras such as video cameras or digital still cameras, solid-state imaging devices have been widely used. In such a solid-state imaging device, there is an exit pupil determined by the aperture of a lens used in an imaging camera. In an imaging camera, the exit pupil distance, that is, the distance from the focal point of the lens to the exit pupil, is limited, so that as the position of the chief ray entering the solid-state imaging device moves from the center of the optical system to the edge of the optical system, The chief ray entering the solid-state imaging device is oblique, and the inclination angle is relatively large. [0003] Figure 9 An example of a solid-state imaging device is shown. In this CCD solid-state imaging device 1, a plurality of sensor sections 2 composed of photodiodes are laid out in an imaging region on a...

Problems solved by technology

In addition, the amount of shading cannot be kept constant with respect to the distance from the center of the image screen, so it is difficult except for exit pupil correction of tiny lenses such as shading correction by electrically shining the edges of the image screen.
