| 348238000 | Using distinct luminance image sensor | 12 |
| 20080259186 | CORRECTING A CAPTURED IMAGE IN DIGITAL IMAGING DEVICES - A method is provided for correcting a captured image. The method comprises determining an illuminant for the captured image. When the determined illuminant matches a reference illuminant the image is corrected with a reference inversion mask. When the determined illuminant matches a first extreme illuminant, the reference inversion mask is modified using a first set of reference point ratios that corresponds to the first extreme illuminant and the image is corrected with the modified inversion mask. When the determined illuminant does not match the first extreme illuminant, a set of reference point ratios are calculated for the determined illuminant. The reference inversion mask is modified using the calculated set of reference point ratios and the image is corrected with the modified inversion mask. | 10-23-2008 |
