Abstract:
A method of operating an image sensor includes generating a plurality of ramping up/down signals, and comparing a correlated double sampled pixel signal produced from an output of a pixel with a correlated double sampled first ramping up/down signal among the plurality of ramping up/down signals in a reset interval. The method further includes comparing the correlated double sampled pixel signal with the correlated double sampled first ramping up/down signal at one sampling time or more in an image interval, and a step of outputting a selected ramping up/down signal among the plurality of ramping up/down signals based on a result of the comparison.
