PURPOSE:To reproduce an original image with different directional/positional mirror-image relations by temporarily storing the original image in a memory, and converting a reproduced image by means of the control of picture element scanning at the time of reading out the data from the memory, CONSTITUTION:When a read key is turned ON, an address data M1ABn is inputted to a bus conversion circuit 32 from a CPU. A conversion controlling circuit 34 controls the multiplexer of the circuit 32 to switch by means of a controlling signal, to switch the connection of an address bus. Accordingly, the address data M1ABn turns to be one M2ABn and is outputted from the circuit 32. Said output is inputted to an adder 33, where an adding data C from an adding controlling circuit 35 is added to said output, and the connection of address bus is switched. In such a way, the image is converted by acting as if the picture element data in the memory is converted.
