Abstract: A device for reversing an image of an object includes selector for selecting a reverse mode and control signal generator for generating a plurality of control signals. The control signal generator outputs a down-counting signal when the reverse mode is selected. A memory stores image data when the memory receives a store-enable control signal from the control signal generator and outputs the stored image data when the memory receives an output-enable control signal from the control signal generator. The device also includes an address generator for generating an address at which the image data is stored in the memory according to a control signal received from the control signal generator. During the reverse mode, the address generator generates an address to sequentially access the memory, beginning with a last address of the memory according to the down-counting signal.
