Abstract
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.

An apparatus for processing a picture, comprising:
- a first filter unit configured to superimpose a first filter onto an input image, and generate a first smooth picture;
- a second filter unit configured to superimpose a second filter onto the input image, and generate a second smooth picture, the second filter having a characteristic different from the first filter;
- a calculation unit configured to calculate a contrast component picture by dividing each pixel value of the input image with the pixel value of the first smooth picture;
- and
- a picture composition unit configured to compose the second smooth picture with the contrast component picture, and generate a composed picture.
