PURPOSE:To omit the address bus set on a picture bus and to simplify the movement of the picture data by providing an exclusive address counter to a picture processing parts respectively and at the same time setting individually the initial values of address counters. CONSTITUTION:The exclusive address counters 14a - 16a are provided to a picture memory 4a and the picture processing parts 5b and 6b to designate the addresses in these parts 5b and 6b. A main control part 7 sets the independent initial address value to each of counters 14a - 16a. Therefore the picture data on the address designated by its own outer 14a are successively outputted to a picture bus 13 from the memory 4a when the counters 14a - 16a are simultaneously started. Thus the parts 5b and 6b can write the picture data sent out successively to the bus 13 into the designated areas of their own counters 15a and 16a respectively. As a result, the movement of the picture data is simplified and the processing efficiency of the picture data is improved. |
