Abstract: In a pixel array within an integrated-circuit image sensor, a pixel (870) includes a photodetector (260) and floating diffusion (262) formed within a substrate. First (881) and second (883) gate elements are disposed adjacent one another over a region (885) of the substrate between the photodetector and the floating diffusion and coupled respectively to a row line (TGr) that extends in a row direction within the pixel array and a column line (TGc) that extends in a column direction within the pixel array.

Abstract: An image sensor architecture with multi-bit sampling is implemented within an image sensor system. A pixel signal produced in response to light incident upon a photosensitive element is converted to a multiple-bit digital value representative of the pixel signal. If the pixel signal exceeds a sampling threshold, the photosensitive element is reset. During an image capture period, digital values associated with pixel signals that exceed a sampling threshold are accumulated into image data.

Abstract: An image sensor architecture is implemented within an image sensor system. Image sensor pixels include pixel regions, and each pixel region includes a photosensor, a reset circuit, and a readout circuit. The readout circuit receives enable signals from an enable signal line, and outputs a pixel signal representative of light captured by the photosensor on a combination input/output line. The reset circuit resets the photosensor in response to receiving a first reset signal on a reset line and a second reset signal on the combination input/output line.
