20090141976 | Color Correction Method and Color Correction Apparatus - A color correction method in which an input image is corrected to generate an output image with an illumination condition different from that in the input image includes: detecting a region of a particular subject from the input image to extract color information on the region; restoring a spectral distribution of illumination in the input image by using the extracted color information and a surface reflectance of the particular subject designated in advance, calculating a spectral distribution of illumination in the output image by using the restored spectral distribution of illumination in the input image and the spectral distribution of designated target illumination, and calculating color information on each pixel of the output image on the basis of color information on each pixel of the input image, the restored spectral distribution of illumination in the input image and the calculated spectral distribution of illumination in the output image. | 06-04-2009 |
20100328740 | METHOD, APPARATUS AND PROGRAM FOR COLOR IMAGE PROCESSING - 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. | 12-30-2010 |

20110268356 | IMAGE PROCESSING METHOD, IMAGE PROCESSING APPARATUS, AND RECORDING MEDIUM - Each pixel of an input image is subjected to first color conversion by means of colorimetric color reproduction and converted to a first color device value of a target color space. Further, a difference DI between a white luminance of an originating color space and a luminance of pixels of the originating color space is calculated. When generating an output image, pixels with a difference DI of 0 keeps the color device value of the originating color space. For the pixels with a difference DI greater than 0, a second color device value is calculated as a color device value of the output image, the second color device value being a sum of the abovementioned color device value and a value which is obtained by multiplying the difference between the first color device value and the abovementioned color device value by a coefficient that is greater than 0 and less than or equal to 1. Due to this, when generating an output image of a target color space from an input image of an originating color space, the color image can be reproduced more brightly while achieving coincident color appearance. | 11-03-2011 |
