PURPOSE:To attain high-speed arithmetic by executing graphic processing in parallel. CONSTITUTION:In logical arithmetic circuits 5-1-5-3, a circuit 31 for executing the logical operation of OR or AND of two data is switched by a control part 32 to select OR or AND logical operation. A multiplexer 33 selects X, -X or '0' on the basis of a signal outputted from the control part 32. An inverter circuit 34 is added to said constitution to process one-picture element data displayed by binary expression. Consequently, 16 (bits)X9 (the number of opera tion steps) = 144 times is obtained as compared with ordinary 8X9=72 times, so that high-speed graphic processing can be attained and the picture processor can be applied to a wider range.
