Abstract: A camera system includes a single lens and an image sensor including a reference pixel array including a plurality of W (white) pixels in a two-dimensional arrangement and a single microlens formed on the plurality of W pixels to be shared, and at least one color pixel array including two W pixels and two color pixels in a two-dimensional arrangement, and a single microlens disposed on the two W pixels and the two color pixels to be shared. Light shielding layers formed with Offset Pixel Apertures (OPAs) are disposed on the plurality of W pixels included in the reference pixel array and the two W pixels included in the at least one color pixel array, respectively, and the OPAs are formed on the light shielding layers in the reference pixel array and the at least one color pixel array, respectively, to maximize a spaced distance between the OPAs.
