Abstract
A method of adaptively reducing power consumption in an image sensor includes using an electronic rolling shutter to reset pixels of the image sensor row by row. Signal charges are read out from the pixels row by row, followed by obtaining an integration time and a frame height. A power-saving signal is generated when the integration time is substantially greater than the frame height, and at least a circuitry that is not required to operate during an active period of the power-saving signal is turned off.
