Abstract:
An image sensor includes a first photo detecting device disposed in a central region of a pixel array portion and a second photo detecting device disposed in an edge of the pixel array portion. The second photo detecting device has a full well capacity which is less than a full well capacity of the first photo detecting device. An imaging device includes the image sensor and an image signal process. The image signal processor compensates for a lens shading effect and a difference between the full well capacity of the first photo detecting device and the full well capacity of the second photo detecting device.
