Abstract
An integrated circuit includes a comparator, a counter and a control circuit. The comparator is configured to generate a comparator output signal in response to a pixel output signal and a reference signal. The counter is coupled to the comparator, and configured to be enabled or disabled in response to the comparator output signal. The control circuit is coupled to the comparator, and configured to enable or disable the comparator by a first enable signal. The first enable signal is generated in response to at least the comparator output signal.
