Abstract

PURPOSE: To reduce the capacity of a memory and to make it possible to use a transmission line of small capacity by coding a linear pattern in a chain shape with a small number of codes, by finding the direction of each picture-element train, the picture-element connection length and variation of the direction in the direction.
CONSTITUTION: A linear pattern stored in frame memory 5 has its initial point (a) detected 6 and initial-point coordinates are coded 7 and sent out. Further, the direction of the picture-element train of the linear pattern is detected 8 successively and coded 9 before being stored in registers 11 and 12 through separator 10. The contents of registers 11 and 12 are coded 13 in the octant direction of the picture-element train and octant-directional one-bit coding is carried out to store the chain length of the segment in 15, thereby finding propriety between directional codes by comparison 16. When the comparison result shows coincidence, codes are stored 17 and when dissidence, on the other hand, octant codes from coder 13, the coded chain length from counter 15 and the directional bit code train from register 17 are sent out respectively.
