METHOD AND APPARATUS FOR WHITE BALANCING DIGITAL IMAGES |
摘要 |
<p>At least one illuminant white point estimate is determined in a color space having radially defined saturation based on a reference image. A chromatic adaptation correction vector (CACV) is determined based on the at least one illuminant white point estimate. Corrected pixels are obtained by applying the CACV (preferably in a cone response color space using a correction matrix based on the CACV) to uncorrected image pixels corresponding to a target image, which may comprise the reference image or another image.</p> |
