Apparatus and method for generating a picture having a high visibility |
摘要 |
A first filter generates a first smooth picture by smoothing an input picture. A second filter generates a second smooth picture by smoothing the input picture. The second filter has a characteristic different from the first filter. A contrast component picture calculation unit generates a contrast component picture by dividing each pixel value of the input picture with the pixel value of the first smooth picture. A picture composition unit generates a composed picture by composing the second smooth picture with the contrast component picture.
