| 20120127322 | APPARATUS, METHOD, AND MANUFACTURE FOR CORRECTING COLOR SHADING IN CMOS IMAGE SENSORS - A device for color shading correction is provided. Local color matching is performed as follows. For each pixel of the image that is being color matched, the RGB value is treated as a one-by-three matrix, which is multiplied by a three-by-three matrix that is generated during factory calibration. The matrix product is a one-by-three matrix that is used as the RGB value for the pixel in the color matched image. | 05-24-2012 |
