A reflection component reconstruction means calculates color information of the object area and a perfect diffusion component, which is a low-frequency component of the object area, and reconstructs a surface reflection component based on the color information and the low-frequency component. A surface reflection component correction means corrects the reconstructed surface reflection component according to a reference surface reflection component that is the surface reflection component set in advance according to the object area. A reproduced color calculation means calculates a reproduced color that is a color obtained by correcting each pixel included in the input image by using the perfect diffusion component and the corrected surface reflection component and generates an output image based on the reproduced color.

摘要： Spectral power distribution of an illumination is restored using color information in a region of the specific object in an input image and a pre-specified representative surface reflectance of the specific object. The surface reflectance in the region of the specific object is restored from the color information and the spectral power distribution of the illumination. The surface reflectance is corrected using three or more pre-specified reference surface reflectances of the specific object. The color in the region of the specific object is calculated from the spectral power distribution of the illumination and the corrected surface reflectance.

摘要： When a projection plane is not uniform due to colors and patterns on the projection plane and ambient environmental light, a reproduced image projected by a projector is made to appear in desired colors. A color correcting apparatus is used, comprising association unit (21), association storage memory 22, color information acquisition unit (23), color conversion calculation unit (23), color conversion storage memory (25), and color correction unit (26). Association unit (21) acquires captured image (7) generated by capturing image (5) projected onto projection plane (2) to establish an association between pixels of image (5) and pixels of captured image (7). Association storage memory (22) records the association. Color information acquisition unit (23) acquires second color information as color information for each pixel of the captured image. Color conversion calculation unit (23) calculates a color conversion for each pixel of the image based on first color information, second color information, and the association. Color conversion storage memory (25) records the color conversion. Color correction unit (26) corrects the input image for colors on a pixel-by-pixel basis using the color conversion.
