摘要：An image sensor having an output of an integral image is provided. The imagesensor includes a pixel circuit, a line accumulator, and a volume accumulator. The pixel

circuit includes a plurality of pixels for capturing pixel values of the pixels. The lineaccumulator is used for accumulating the pixel values of the pixels from a first pixel to atarget pixel in a target pixel line of the image so as to obtain an accumulated line pixelvalue. The volume accumulator is used for adding the accumulated line pixel value outputby the line accumulator to an integral pixel value of the pixel corresponding to the targetpixel in a previous pixel line of the target pixel line, and using an adding result as theintegral pixel value of the target pixel, so as to output the integral pixel value of thetarget pixel to form an integral image.
