A black level correction circuit includes: a counter counting a black signal level of an image; a black level determination section determining a feedback gain by comparing data outputted from the counter with a previously set threshold; an average value calculation section calculating an average value from data supplied from the counter; a feedback calculation processing section selecting the feedback gain by a control signal supplied from the black level determination section and calculating the selected feedback gain and the averaged data; and a digital-analog converter correcting data to which feedback calculation processing has been performed and converting the corrected data into analog data to output an analog black signal.
