Abstract

PURPOSE:To enable to prevent a lack of a picture, by storing a digital picture information in order in the line memory and directly in the arithmetic circuit, by the switching circuit, OR-processing it together with the picture information of an adjacent scanning line, compressing them to one scanning line, and reproducing it. CONSTITUTION:For instance, in case a scanning line is sampled to 1/3, the switch 6 switches whenever a driving signal is provided from the switch driving circuit 7, selects in order an output destination of 1 scanning line, and the respective digitized picture signals of 1 scanning line are provided to the memories 8, 9, and directly to the arithmetic circuit 11 and are stored temporarily. In this case, the line memory control circuit 10 reads out and controls the line memories 8, 9, the arithmetic circuit 11 inputs the picture information to three scanning lines, executes OR- processing, and stores it in the frame memory 3 as picture information of one line portion. When it is reproduced, it is possible to obtain an approximately compensated picture (d), which is not a lacking picture (c), without increasing the memory capacity of the memory.
