Abstract
An image processing apparatus includes an image decomposing unit that decomposes a pixel value of each pixel forming an original image into an illumination component and a reflectance component to generate an illumination component image, and an image composing unit that reflects the illumination component on a sample image serving as a sample of image, and combines the sample image with the illumination component reflected thereon to the original image.
Claims20
An image processing apparatus comprising:
- at least one processor configured to execute:
- an image decomposing unit configured to decompose a pixel value of each pixel forming an original image into an illumination component and a reflectance component to generate an illumination component image;
- and
