<p>PROBLEM TO BE SOLVED: To rapidly perform a vertical-horizontal or combined inversion display of an image figure and to make it possible to reduce the capacity of the figure ROM data by providing one or both between a data revision means revising an output order of a pixel dot of the read-out figure data and a line buffer address revision means. SOLUTION: A display part 2B is provided with an output part 27B revising the display figure data in an optional dot order when the data are stored in a line buffer 3 in addition to a CPU part 1 and the line buffer part 3. The storage order of the storage data is revised by revising the dot address of the figure data given to the line buffer 3 in the optional dot order, and only the optional dot order for a horizontal direction in a reference figure or an optional dot is displayed. That is, the figure ROM data are outputted as it is in a regular display, and the inverted figure ROM data are outputted in an inversion display. Further, in such a case, an address supply method to the line buffer 3 may be inversely revised, and an inversion dot order conversion display may be performed.</p> |
