Imaging device including a plurality of lens elements and a imaging sensor
First Claim
1. An imaging device for imaging an object, comprising:
- a lens array comprising a plurality of lens elements arranged in a matrix and having optical power in at least one surface; and
an image sensor comprising a plurality of imaging regions arranged in a matrix, each of the imaging regions having a plurality of photoelectric conversion sections and receiving an optical image of the object formed by corresponding one of the lens elements so that the optical image is converted into an electric image signal, wherein;
each lens element and the imaging region corresponding to the lens element constitute an imaging unit,the imaging units include a first imaging unit and a second imaging unit,a first region of the object of which image is received by the first imaging unit is fully included in a second region of the object of which image is received by the second imaging unit, andthe second region of the object is larger than the first region of the object.

Abstract
An object of the present invention is to provide: a thin imaging device in which a high image resolution is obtained and in which the resolution does not uniformly vary even when the shooting distance is changed; and a lens array used therein. The present invention relates to an imaging device comprising: a lens array 130 constructed by arranging in parallel a plurality of lens elements having optical power in at least one surface; and an image sensor 110 in which an optical image formed by an optical system having each of the lens elements is received by each of mutually different imaging regions each having a plurality of photoelectric conversion sections so that the optical image is converted into an electric image signal, wherein each lens element and the imaging region corresponding to the lens element constitute an imaging unit, while the imaging units have diverse imaging region areas. The present invention relates also to a lens array used therein.
