PURPOSE:To simplify the constitution of the titled device and to attain ease of the switching of various magnification factor and oblique line compensating systems, by changing a part of the contents stored in a read only memory and a control circuit in response to the change in the magnification factor and oblique line correcting system. CONSTITUTION:An original signal of a bit pattern of a scanning line L performing magnification and oblique line compensation is recorded on an L scanning line memory 11 and an original signal of an (L-1)th scanning line just before the scanning line L is recorded in an (L-1)th scanning line memory 12. Further, the K-th picture element N of an original picture input terminal 13 is applied to a shift register 14, the K-th picture element N from the memory 11 is read out and written in a shift register 15 and the picture element N on the scanning line (L+1) is written. Further, the K-th picture element N is read out from the memory 12 similarly and written in a shift register 16. Moreover, information at a control information input terminal 18 of the magnification factor and oblique line compensation and a clock at a clock input terminal 22 are applied to a control circuit 19. Then, a part of the content of the read only memory 17 inputting the output of the registers 14-16 and the circuit 19 is changed to simplify the constitution of the device. |
