ABSTRACT:
The image data coding apparatus of the present invention includes a First-In, First-Out memory, a pixel color discriminating section, black and white run length calculating sections, black and white code look-up tables, parallel input/serial output shift resisters, and a valid bit detecting section. The FIFO memory sequentially reads binary image data, and outputs them in the inputted order. The pixel color discriminating section discriminates the color of the pixels outputted from the FIFO memory. The black and white run length calculating sections calculate the run lengths of the pixels after the discriminations of the color of the pixels by the pixel color discriminating section. The code look-up table outputs the relevant codes in byte units after receipt of the code address from the black and white run length calculating sections. The parallel input/serial output shift register converts the parallel output data of the look-up table into serial data. The valid bit detecting section outputs parallel data in byte units after extracting only the valid bits among the serial data outputted from the parallel input/serial output shift register.
