Abstract
A solid-state image pickup device has a photosensitive chip and an array of microlenses arranged on the incident side of the photosensitive chip. A correction lens is arranged on the incident side of the microlens array to reduce incident angles of light entering the microlenses. The solid-state image pickup device may be incorporated in a head of an endoscope of an endoscopic apparatus to receive light from an optical system arranged in the head. The head includes a unit for changing paths of light to the microlenses to reduce incident angles of the light entering the microlenses.
