<p>A video correction circuit of the invention includes an detection unit for detecting the cumulative light-emission frequency data on each pixel by sampling video data supplied to a display device having a plurality of pixels; a cumulative data storage unit for storing the cumulative light-emission frequency data on each pixel; an adder for adding the cumulative light-emission frequency data on each pixel detected by the detection unit to the cumulative light-emission frequency data on each pixel stored in the cumulative data storage unit, thereby writing the result to the cumulative data storage unit as new cumulative light-emission frequency data; and a correction unit for correcting the video data based on the cumulative light-emission frequency data stored in the cumulative data storage unit, thereby outputting the corrected video data to the pixel portion. The pixels are provided with light-emitting elements of a plurality of colors. The cumulative light-emission frequency data is divided into a plurality of data fragments, each of which is stored in each of the plurality of memories for each color of the light-emitting elements.
