<p>The circuit modulates the image data to the mosaic image data with a dual port memory so that the non-educational scene of the adult movie is covered by the mosaic pattern. The method comprises steps; (a) converting the analog signla of the colour difference with sequence of Y, R-Y, B-Y to the n bit digital signal with sequence of R-Y, Y, Y, B-Y, Y, Y and the L bit digital one once more; (b) storing the converted signal to a memory (50); (c) reading the digital signal having the 7th unit corresponding to the 1 horizontal scanning period from the memory repeatedly during the (b) step; (d) convertering and providing the one of read data to the analog signal of the colour difference with sequence of Y, R-Y, B-Y for the 6th period corresponding to the periods for a few dot data.</p> |
