Abstract
PURPOSE:To obtain the mosaic picture stable without flickering, by taking the write-in operation to the picture memory section once for four-fields at the reproduction of mosaic picture. CONSTITUTION:When the video input signal V1 is in digital conversion and write- in control to the video memory section 14 is made, the write-in every field is made at the reproduction of original picture and the wirte-in once per four-field is made to obtain the mosaic picture. Accordingly, since the representing data not changed is used, the mosaic picture stable without flickering can be obtained even at the mosaic conversion of the still picture or the picture close to it.
