<p>A digital wipe pattern generating device is disclosed, which comprises address generators (101, 108) for counting horizontal and vertical synchronization pulses to generate addresses; calculator (117) for obtaining wipe address data by effecting a plurality of sorts of calculations in a digital manner while using predetermined coefficients, combining and selecting arbitrarily results of the calculations; and a device (107) for generating a wipe pattern by slicing the wipe address data at a predetermined slice level. Since all the processings are effected in a digital manner, it is easier to fabricate the device, using ASICs or ICs, and thus the scale of the circuits can be reduced. <IMAGE></p> |
