Abstract
An image processing device including an image signal reception unit configured to receive an image signal of an image to be processed; a density reduction area detector configured to detect a density reduction area satisfying predetermined image density reduction requirements in the image to be processed based on the image signal; a specific image area detector configured to detect a specific image area satisfying predetermined specific image requirements different from the predetermined image density reduction requirements in the image to be processed based on the image signal; and a density controller configured to reduce density of the density reduction area detected by the density reduction area detector in a non-specific image area other than the specific image area detected by the specific image area detector, and to not reduce density of the density reduction area in the specific image area.
