Abstract
An image processing device detects the correlation between a pixel to be removed in thinning pixel blocks generated by using a delay in horizontal and vertical directions and an adjacent pixel. The device then determines a coefficient corresponding to the correlation. From the pixel to be removed and the adjacent pixel, pixel data is generated by using a predetermined calculation equation. Thinning and reduction of each pixel block in the horizontal and vertical directions thus occurs.
