Original Abstract Submitted

a single-slope analog-digital (ad) conversion circuit for performing ad conversion on a pixel signal includes a plurality of comparators configured to receive a plurality of pixel signals and a ramp signal, a count pulse controller configured to generate a counter input signal for counting an average value or a weighted average value of the plurality of pixel signals from a clock signal, based on outputs of the plurality of comparators, and a counter configured to count the average value or the weighted average value of the plurality of pixel signals based on the counter input signal.
