Abstract
Official abstract text for this publication.
An image processing device performs image processing on image data obtained by receiving light emitted from a light source and then reflected from an object to be read with a light receiving element. The image processing device includes a determination unit configured to determine whether or not a color of each pixel in the image data belongs to a predetermined correction target color range and a correction unit configured to perform correction to reduce the density of a pixel of the color belonging to the correction target color range.
