20090033677 | COMPUTER-IMPLEMENTED GAMUT MAPPING - In gamut mapping, as the brightness of the original color (S) increases further and further beyond the source gamut ( | 02-05-2009 |
20090096809 | COLOR QUANTIZATION BASED ON DESIRED UPPER BOUND FOR RELATIVE QUANTIZATION STEP - A computer system ( | 04-16-2009 |
20090097760 | REPRESENTATION AND QUANTIZATION OF DIGITAL IMAGES AND EVALUATION OF COLOR DIFFERENCES - Digital image data are coded in a color coordinate system bef where b=0.3·ln B and B, e, and f are Bef coordinates. This coding has high perceptual uniformity with respect to coding errors. A color difference formula is provided, with the color difference defined as 100 √{square root over (Δb | 04-16-2009 |
20090102856 | COLOR COORDINATE SYSTEMS AND IMAGE EDITING - Color is edited using a color representation including digital values B (brightness), e and f such that B=√{square root over (D | 04-23-2009 |
20090174719 | WHITE BALANCING THAT USES VALUES OF WHITE-BALANCED COLORS ON THE VISIBLE GAMUT'S BOUNDARY - White balancing is performed using a mapping that maps the visible gamut's boundary into itself. A predefined color W | 07-09-2009 |
20100194772 | IMAGE DISPLAY USING A COMPUTER SYSTEM, INCLUDING, BUT NOT LIMITED TO, DISPLAY OF A REFERENCE IMAGE FOR COMPARISON WITH A CURRENT IMAGE IN IMAGE EDITING - When editing an image ( | 08-05-2010 |
20110158526 | IMAGE PROCESSING INCLUDING, BUT NOT LIMITED TO, LOGARITHIMIC CODING IN COLOR COORDINATE SYSTEMS INCLUDING SYSTEMS WITH A COORDINATE DEFINED BY A SQUARE ROOT OF A QUADRATIC POLYNOMIAL IN TRISTIMULUS VALUES AND, POSSIBLY, BY A SIGN OF A FUNCTION OF ONE OR MORE OF TRISTIMULUS VALUES - Color is edited using a color representation including digital values B (brightness), e and f such that B=√{square root over (D | 06-30-2011 |
