Abstract
It is difficult to reproduce an input image more faithfully while enlarging a dynamic range and color gamut, in a reproduced image obtained by overlapping output images by a projector and printer. An image processing apparatus () transforms an input signal () into an RGB signal for a projector () and a CMY signal for a printer (). In this case, the image processing apparatus () uses a transformation LUT, which is generated based on the spectral distribution characteristics of the projector () and the spectral reflectivity characteristics of the printer (). By overlapping images formed by the projector () and printer () based on the transformed image signals, an input image can be reproduced more faithfully while enlarging the dynamic range and color gamut.
