Abstract
A vertical peaking method and the apparatus thereof comprises the steps of selectively passing vertical and horizontal detail information by low-pass filtering a video signal to detect image brightness, subtracting the detected image brightness data signal from a maximum allowable value, and multiplying the signal obtained from the subtraction operation by the vertical peaking signal, adding it to the luminance signal to output the luminance signal vertically peaked according to image brightness. The apparatus accomplishes the steps via hardware, in which the amount of vertical peaking is controlled by the image brightness, so that the vertical peaking of an image is accomplished uniformly.
