Patent ID: 8144226

Claim:
A complementary metal-oxide-semiconductor (CMOS) imaging system-on-chip (iSoC) sensor system, comprising: a pixel array constructed as an array of two-by-two pixel structures, comprising: a first two-by-two pixel structure and a second two-by-two pixel structure, wherein the first two-by-two pixel structure and the second two-by-two pixel structure respectively include four pixels configured to share at least one component; a plurality of read buses respectively associated with columns of two-by-two pixel structures of the pixel array, comprising: a first read bus associated with the first two-by-two pixel structure and a second read bus associated with the second two-by-two pixel structure; and a plurality of multiplexers respectively positioned at ends of pairs of read buses, comprising: a first multiplexer configured to select one of the first read bus or the second read bus from which to transfer a first sampled signal, from one of the first two-by-two pixel structure or the second two-by-two pixel structure, to a first signal chain; and a second multiplexer configured to select one of the first read bus or the second read bus from which to transfer a second sampled signal to a second signal chain, wherein the second multiplexer selects a disparate read bus from the first multiplexer, wherein the first multiplexer and second multiplexer coordinate selection such that signal information, from the first two-by-two pixel structure and the second two-by-two pixel structure, corresponding to a same color plane are transferred to a same signal chain.
