Abstract
A method for correcting the contour of an image, in which contour signals are independently extracted from image signals obtained in a plurality of channels; the thus extracted contour signals are mixed with each other at a fixed or variable mixing ratio to produce a contour correction signals; and the thus obtained contour correction signals are added to the image signals in the respective channels. Therefore, the noise included in the contour signals are averaged so as to be decreased; and thus it is possible to prevent the decrease the SN ratio of the image signals, which is caused by correcting the contour of the image. Further, since the contour signals are independently extracted in each channel, it is possible to independently correct the contour of the image in each channel.
