Abstract
Provided is an image processing apparatus including a color conversion unit that performs color conversion to convert an original image to a luminance image and to a chromaticity image, an illumination image generation unit that generates an illumination image having an illumination component of the luminance image as a pixel value from the luminance image, a reflectance image generation unit that generates a reflectance image having a stabilized reflectance component of the luminance image as a pixel value, a luminance reproduction image generation unit that enhances the reflectance component of the luminance image to generate a luminance reproduction image reproduced with being improved visibility of the luminance image, and an inverse color conversion unit that performs conversion inverse to the color conversion performed by the color conversion unit on the luminance reproduction image and the chromaticity image.
