However, the emphasized area is an edge of the dark area and low-frequency component in the bright area of the object, but no effect appears in the low-frequency component of the dark area and the edge component of the bright area. Therefore, the method in Japanese Application Kokai No. 2001-352486 does not correspond essentially to the method of emphasizing the contrast.
The method of emphasizing the contrast is disclosed in Japanese Application Kokai No. 2003-8935. In the method disclosed in Japanese Application Kokai No. 2003-8935, since the contrast with respect to a local area in a screen is emphasized, emphasizing of the contrast is achieved by calculating a superimposed value using pixel values in the periphery of a target pixel using a smoothing'School'

The problem is, it returns two identical rows!
