Abstract
The present invention provides an image pickup apparatus which photoelectrically converts an optical image transmitted through a photographing optical system and formed on a photoconductive surface. The image pickup apparatus includes a first microlens array and a second microlens array each of which has a focal position in the vicinity of the photoconductive surface and is arrayed in a two-dimensional manner, a first photoconductive element group including units each formed by a single photoconductive element which is disposed in the vicinity of the focal position of the first microlens array and outputs a first video signal, and a second photoconductive element group including units each formed by a pair of photoconductive elements which are disposed in the vicinity of the focal position of the second microlens array and output a pair of second video signals.
