Abstract: A pixel array comprise a green pixel comprising a first green optical filter and a first clear filter, a red pixel comprising a red optical filter and a first special filter, a blue pixel comprising a blue optical filter and a second special filter, and an IR pixel comprising an IR optical filter and one of a second green optical filter and a second clear filter, where the first special filter suppresses a transmission of IR at a stopband centered at 850 nm at a first IR minimum transmission, and the second special filter suppresses a transmission of IR at the stopband centered at 850 nm at a second IR minimum transmission, and where the first minimum IR transmission is different from the second minimum IR transmission.
