Abstract
A mosaic picture generation circuit for reproducing a color television signal in a mosaic fashion on a television display comprises a circuit for writing an analog-to-digital converted signal of a composite video signal in a memory, a circuit for reading out data of one wave of color burst to be repeated in each mosaic block each time the block is scanned, a circuit for repeatedly outputting the read out data on the same scanning line in the same block, a circuit for shifting the output data in the same block by half wave of color burst every other scanning line, a circuit for replacing data of half wave of first color burst on a scanning line on which the shifting is not made with former half data of one wave of color burst to be repeated in an immediately preceding block, and a circuit for delivering out the output data after digital-to-analog conversion. A mosaic picture can be produced by using a composite video signal without any previous processing so that a clear mosaic picture free from irregularity can be produced with a simplified circuit construction.
