Abstract

PURPOSE: To perform stable mosaic conversion where representative data is not changed in the reconstitution of mosaic units, by doubling picture storage parts to switch reading and writing alternately in case that picture data of picture storage parts is read to perform a special mosaic processing of the picture.
CONSTITUTION: Video input signal V1 is subjected to analogue.digital (A/D) conversion and serial.parallel (S/P) conversion in 11 and 12 respectively and is stored in picture storage part 14. The reading of picture storage part 14 is controlled synchronously with the scanning timing of the television screen, and read picture data constitutes a picture. Mosaic control part 19 designates the read address as a mosaic unit by address control part 15 to constitute the picture with representative data and obtain a mosaic picture. Picture storage part 14 is doubled with parts 14a and 14b, and the writing state and the reading state are switched alternately, and writing and reading are performed stably.
