Patent ID: 7973843

Claim:
A pixel array, comprising: a plurality of pixels, each pixel including: a photoactive region and an active region separated by a first transfer gate, anti-blooming and storage regions selectively connectable to the active region and separated from the active region by second and third transfer gates, respectively, and a reset gate selectively connectable to the storage region; and a controller operable to control the transfer and reset gates of the plurality of pixels, wherein the controller is operable to: set the active region of a pixel to a predetermined charge level; cause charge accumulated in the photoactive region of the pixel during a non-charge integration period to be transferred to the active region of the pixel; cause charge from the active region to be transferred to the anti-blooming region of the pixel; reset the active region to the predetermined charge level; cause charge accumulated in the photoactive region during a charge integration period to be transferred to the active region of the pixel; and cause charge from the active region to be transferred to the storage region of the pixel.
