Patent ID: 7138663

Claim:
A solid-state image sensor comprising: a micro lens which condenses light to an opening provided in a mask layer; a first optical element which receives light condensed by said micro lens through said opening, to divide the light into light to be transmitted and light to be reflected in accordance with wavelengths of the light received; a first light receiving surface which receives light passed through said first optical element; a second optical element which receives light reflected by said first optical element to divide the light into light to be transmitted and light to be reflected in accordance with wavelengths of the received light different from those of said first optical element; a second light receiving surface which receives light reflected by said second optical element; a third optical element which receives and reflects light passed through said second optical element; and a third light receiving surface which receives light reflected by said third optical element, wherein the mask layer masks the second and third optical elements so that light passed through the micro lens is not directly incident to the second and third optical elements.
