Abstract:
An example embodiment of an image sensor may include a controller and a plurality of up/down ripple counters. The controller may generate a first control signal and a second control signal. Each of the up/down ripple counters may perform a stop operation or a count operation in response to a corresponding one of a plurality of operation control signals generated based on at least in part on the first control signal. The count operation may be an up-count operation or a down-count operation based on the second control signal. The image sensor may also include a plurality of memory chains. Each of the memory chains may receive a count value output from the up/down counters and may shift the received count value in response to a third control signal and a fourth control signal output from the controller.
