Abstract

PURPOSE:To enable to obtain the special effect for an arbitrary part of screen in an arbitrary time, by changing the output of the coefficient storage circuit at least in synchronizing with the horizontal and vertical synchronizing signal, in the device of picture conversion through special digital filter. CONSTITUTION:With the instruction from the control circuit 14, a given coefficient is read out from a different plurality of coefficients depending on the special effect stored in the memory in advance of the coefficient readout circuits 11-13, and it is sequentially stored in the coefficient storage circuits 8-10. Each output stored in the coefficient storage circuits 8-10 for a given time is multiplied with each delay circuit output of the digital video signal (a) at the multiplication circuits 4-6, the result is added at the addition circuit 7 and output as the converted digital signal (b). Accordingly, the frequency characteristics of transversal filter is changed in the order of specified time at the location of space of screen, enabling fog effect.
