Abstract
A flicker detection circuit is provided. The flicker detection circuit may include a flicker detection correlated double sampling (FD CDS) circuit including first to sixth switches turned on or off based on a control signal, and first to fourth capacitors, the FD CDS circuit being configured to receive a flicker pixel signal output from at least one pixel, summate with an output offset signal, and amplify the summation based on a gain to form a flicker detection signal; and an analog-to-digital converter (ADC) configured to quantize the flicker detection signal.
