Device and method for estimating light source, image pickup device and image processing method |
| abstract |
The subject of the invented method for estimating a light source is to improve the color reproduction quality of white balance adjustment so as to estimate the chromatic characteristic of an unknown light source of a photographed scene from a sensing response. In the method for estimating a light source, a projection converting section 6, which uses a parameter obtained from the spectral sensitivity characteristic of known image pickup means 4 and the spectral characteristic of a supposed test light source 1 through colorimetrical approximation-possible calculation, estimates the correct photographing light source 2 with respect to a sensor response value 5 and evaluates correctness of a plurality of test light sources 1 based on the distributed state of sample value of the projected scene by means of an evaluating section 10. |
