Abstract
The present invention provides an image processing device that reproduces the color of an input image more faithfully under different environment illumination without the need to prepare a different signal separation LUT for different environment illumination. An image processing device in one embodiment of the present invention generates data for generating an overlap image by overlapping an image formed by an image forming device and an image projected by an image projection device. The image processing device includes a generation unit configured to, based on input image data, generate first image data for the image forming device and second image data for the image projection device, a first acquisition unit configured to acquire environment illumination information relating to environment illumination in generating the overlap image, and a correction unit configured to correct the second image data based on the environment illumination information.
