Patent ID: 8089542

Claim:
An apparatus comprising: an array of active pixels disposed on a silicon substrate, each active pixel of the array comprising a respective photodiode, the array to provide signals associated with an image to be focused on the array; a controller disposed on the substrate and coupled to the array to provide correlated double sampling of signals associated with the image; an analog-to-digital converter disposed on the substrate and coupled to the array to convert analog signals associated with the image into digital signals associated with the image; a digital signal processor disposed on the substrate and coupled to the analog-to-digital converter to perform signal processing on digital signals associated with the image; non-volatile memory disposed on the substrate having program code stored therein to control the processor; a control input to receive a signal to select one of at least two speeds at which signals associated with a frame of the image are to be provided from the digital signal processor; and a layer of material disposed proximate to the controller, the analog-to-digital converter, the processor, and the non-volatile memory, wherein the layer of material is at least partially absent proximate to the array to pass light to the array and to block light from regions outside the array.
