ABSTRACT:
A memory read control unit (606) reads out image data of one pixel from a memory (603) in synchronism with a clock signal. On the basis of the image data of one pixel, a converting unit (604) converts the density of a corresponding pixel into digital data of a plurality of bits and stores the digital data in a shift register (606). A pixel-piece insertion and deletion control unit (607) inserts data of one bit into the shift register or deletes data of one bit from the shift register. The pixel-piece insertion and deletion control unit (607) estimates a data storing state in the shift register and controls image data read-out from the memory (603) in accordance with the estimated data storing state.
