ABSTRACT:
A character image generating circuit includes a text buffer for storing character code data corresponding to one page, a first memory for storing character image data corresponding to a section of one page, and a second memory for storing compressed character image data corresponding to one page. A depiction control unit coupled with a font memory is provided for converting the character code data, a section at a time from the text buffer, to character image data which is temporarily stored in the first memory. The depiction control unit also compresses the character image data obtained from the first memory to produce compressed character image data which is stored in the second memory. The second memory further receives compressed character image data of other sections. A reconstruction circuit is provided for reconstructing the compressed character image data of one page from the second memory back to the original character image data.
