Abstract
PURPOSE: To make it possible to synthesize screens freely on a memory by causing levels of video signals near boundaries of an original screen and a rewritten screen to agree with each other and coding the level and writing the level in a storage unit.
CONSTITUTION: In storage of video signals of video source 12 into frame memory 15, if the output of A/D converter 16 agrees with contents x1 of register 19, namely, coordinates of the lower limit of the boundary part of a screen, for example, white- level signals are inserted to video signal substitution circuit 13 in stead of signals of video source 12, and the output of circuit 16 is outputted up to contents x2 of register 20, namely, the upper limit of coordinates of the boundary part. Coding circuit 14 takes correlation of each picture element in the scanning direction in respect to the output of circuit 13 and codes it. Frame memory 15 stores one-screen components of coded data. Video signals of video source 12' are written into memory 15 only in a range of the output of circuit 16 over xi (x1≤xi≤x2). Synthesized picture data obtained in this manner is stored in picture file 8.
