Abstract

It will be said that a method for changing a sharpness intensifying coefficient with parameters of two signals, i.e. a sharp signal and an edge signal has not been established up to these days in spite of existing these two signals which are considered as parameters in the sharpness intensifying process. In order to intensify sharpness of a picture image to be processed, a difference between a sharp signal and an unsharp signal of the picture image is first obtained as an edge signal and the thus obtained edge signal is then multiplied by a coefficient for determining the degree of the sharpness intensification thereby to obtain a sharpness intensifying signal. The sharpness intensifying signal is added to the sharp signal in the adder, whereby sharpened signal is outputted from the adder.
