Abstract

PURPOSE: To limit an increase in compressed data by using as compressed data in one page a raster-unit mixture of compressed data and original data.
CONSTITUTION: A Chinese-character code is arrayed by editing circuit 1 into an output image of a character pattern. Original data for one raster, sent from editing circuit 1 to raster buffer 2, is compressed by compressing circuit 3 and outputted to compressing raster buffer 6 and counter 5. Compressing circuit 3 compares the number of bits of one raster of original data with the number of counted bits of counter 5 and when the contents of counter 5 exceed the volume of original data, compression is stopped to store the contents or original raster buffer 2 in page buffer 8 from selector 7. When not, the contents of compressing raster buffer 6 are transferred to page buffer 8. Then a flag showing which of rasters has been transferred from compressing circuit 3 to page buffer 8 is set in flag buffer 4.
