Abstract: Various embodiments of the present technology may comprise methods and apparatus for a light sensor with a precharge circuit, such as for charging an internal node of a sensor to a starting voltage equal to an ending voltage of a different sensor. The methods and apparatus may comprise sequentially reading out the voltages of photosensitive elements and selectively activating the precharge circuit of one sensor during readout of the last photosensitive element of a different sensor.
