Claim Text:
1. A substrate stacked image sensor having a dual detection function, comprising: first to fourth pixels formed in a first substrate; and a fifth pixel formed in a second substrate and having a size different from sizes of the first to fourth pixels, wherein the first to fourth pixels and the fifth pixel are electrically bonded to each other, and a sum of pitches of the first to fourth pixels is equal to a pitch of the fifth pixel so that sensor resolution of the first substrate is different from sensor resolution of the second substrate, and wherein relative distances of objects in an image are calculated through frequency component analysis for each color from RGB focus data of the second substrate and RG or RG+IR focus data of the first substrate using RGB or RGB+IR and the chromatic aberration of an external optical system, and for each color according to physical distances of upper and lower layers, to be used as basic data for restoring a three-dimensional image.
