Abstract:
A pixel circuit includes a pixel-capture device having a pixel node and operable to convert light intensity into a pixel signal at the pixel node, the pixel signal representing a captured pixel. A row node carries a row signal that is operable to both (a) enable passage of the pixel signal from the pixel node to a column node during a readout phase of the captured pixel, and (b) set the pixel node to a predetermined signal level during a reset phase of the captured pixel. The reset phase and the readout phase are configured to occur during different time intervals. A reset node is included for carrying a reset signal that is operable together with the row signal to (a) enable passage from the pixel node to the column node during the readout phase, and (b) set the pixel node to predetermined signal level during the reset phase.
