Abstract
Abstract An image processing apparatus has: a setting unit configured to set a division way for dividing an image data; a processing unit configured to divide the image data in accordance with the division way, and perform a predetermined process on each of resulting division areas; and an extracting unit configured to extract a unique portion from the image data. The predetermined process includes an averaging process on each of division areas obtained by dividing the image data in accordance with the division way, a quantization process for quantizing values obtained by the averaging process, and an addition process for adding values obtained by differentiating the division way. The setting unit sets a first division way for the predetermined process for a first area that is associated with the device in occurrence position of the unique portion and a second division way for a second area other than the first area.
