| titleOfInvention | Automatic white balance correction method, device and computer storage medium |
| abstract | The invention provides an automatic white balance correction method and device. The method comprises the following steps: determining a white pixel statistical region according to the chromaticity distribution characteristics of white pixel points under a light source; counting pixel points of the image to be corrected falling into the white pixel counting area, and calculating white balance gain; carrying out coarse correction on the image to be corrected according to the white balance gain; converting the corrected image from RGB color space to YUV space, and selecting white pixel points in the YUV space; calculating average chroma and color cast error of white pixel points in YUV space; and when the color cast error is larger than a preset value, performing fine correction on the image after the coarse correction by using a fine color cast correction gain. The invention has the advantages of easy construction of the required priori knowledge, simple algorithm, easy hardware realization and good correction effect. |
