Abstract

PURPOSE: To enhance the efficiency of the coding by counting from the first time when the break-point digit number every digit corresponding to the length portion of the block exceeds the binary counted value in run length coding system.
CONSTITUTION: In case of converting into one block 3 bit run length code, the length portion is counted by binary of two digits. In case of the input information exceeding the saturation value, the counted value up to that time is cleared and the counting is done from the first time. Thereafter, the counting is done four digit binary corresponding to the length portion of two block and is continued until the content becomes the saturation value. Then, in accordance with the next one input information, the counting contents to that time is cleared. The white or the black level bit is added to these counted values and the similar operations are repeated as follows. Thus, the information in large generation probability is assigned by a short code, thereby the coding being done effectively.
