Abstract
An image processing device in accordance with the present invention processes image data obtained by reading an original image including an image portion and a background portion to subdivide the original image into a plurality of images, the image data including density data representing density of each image. The device includes a device for outputting background density data, a device for outputting density coefficient data, a background color removing device for decreasing a value of density data corresponding to the background portion based on the background density data, and a density correcting device for increasing a value of density data corresponding to the image portion based on the density coefficient data.
