PURPOSE:To prevent a picture from being abnormal by a linkage processing function by dividing the picture into plural areas by an error dispertion method, etc., and controlling the ON/OFF of the linkage processing function when a special processing is executed to the linked part of the respective areas. CONSTITUTION:The states of SW 1 and 2 are read and it is judged whether a picture input device 1 or a pattern generating circuit 10 is selected. As a result, when the both SW 1 and 2 are '0', an instruction is applied to a selector 11 so as to select the device 1. When the SW1 is '0' and the SW2 is '1', the output of a picture pattern 1 is instructed to the circuit 10. When the SW1 is '1' and the SW2 is '0', the output of a picture pattern 2 is instructed and when the both SW 1 and 2 are '1', the output of a picture pattern 3 is instructed. After executing the above mentioned processings, an instruction is outputted to the selector 11 so as to select the circuit 10. When the switch of input picture data is finished, the selector 11 reads the states of SW 3 and 4 and judges the states. Then, the linkage processing is automatically turned ON/OFF corresponding to '0' and '1'. |
