Original Abstract Submitted
A circuit includes a comparator configured to generate a first conversion gain output signal by comparing a first pixel signal corresponding to a first conversion gain with a first ramp signal, and generate a second conversion gain output signal by comparing a second pixel signal corresponding to a second conversion gain with a second ramp signal, and a counter configured to count pulses of the first conversion gain output signal, output a counting result as a first digital signal, and determine whether an output of a second digital signal corresponding to the second conversion gain is required, based on the first digital signal. The first conversion gain is higher than the second conversion gain, and based on determining that the output of the second digital signal is not required, the counter is further configured to control the comparator such that the second conversion gain output signal is not generated.
