| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | When we take a photograph，excessive light over the dynamic range of the camera can be injected by proximal lighting or long exposure. Such excessive light will be clipped to the maximum intensity of the range. When this saturation occurs, the color balance may be broken. For relaxing the problem, many digital cameras have a special function that substitutes saturated colors by non-saturated likely colors. The likely colors are estimated from the pixels surrounding the saturated pixels. However, this method does not estimate the original colors over the maximum value but finds consistent colors less than the maximum value. In this report, we propose a method for estimating original colors over the maximum value by using Nearest Neighbor Search. This method can be applied to those colors up to two saturated color components. | |
