PURPOSE:To reduce the circuit scale by applying picture conversion by the 1/9 division method and the picture conversion by the OR method by means of one and same circuit. CONSTITUTION:A conversion picture element address calculation circuit 1 calculates a conversion picture element address 7. A reference 4-picture element output circuit 2 outputs a reference 4-picture element 6 (I00, I01, I10, I11) in response to a conversion address 7. Then a multi-system picture element conversion picture element circuit 4 applies picture element conversion by the 1/9 division method or the OR method according to a command of a conversion system command circuit 3 in response to the reference 4-picture element 6 (I00, I01, I10, I11) and the conversion picture element address 7 and a conversion picture element output 5 is obtained. Thus, the scale of the circuit is reduced. |
