US 5,969,773 A · Device for reversing an image of an object

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.

Dependent claims

A device for reversing an image of an object, comprising:

means for selecting a reverse mode;
means for generating a plurality of control signals, and for outputting a down-counting signal when the reverse mode is selected;
a memory for storing image data when the memory receives a store-enable control signal from the control signal generating means and for outputting the stored image data when the memory receives an output-enable control signal from the control signal generating means;
and
means for generating an address at which the image data is stored in the memory according to a control signal received from the control signal generating means, and, during the reverse mode, generating an address to sequentially access the memory, beginning with a column address which precedes a last column address of the memory according to the down-counting signal.
