Abstract
PURPOSE: To realize the area measurement for the region via a small-capacity memory device by attaching the labels to the runlength data obtained through the prescribed method and in the detection sequence of the 0 part areas.
CONSTITUTION: The subject is scanned by quantization means 1 to produce 1 at the beginning and finish of the scanning, and then 1 and 0 are added to the spots belonging and not belonging to the pattern part. Thus the runlength data is formed based on a pair of data formed with 0 position A changing to 0 to from 1 on one scanning row and 1 position B changing to 1 from 0 after detection of A. At the same time, the labels are given to the data in the detection sequence of the 0 part regions, and the connection relation is detected and memorized for the 0 part region. Then the counting is given with every same labels via 0 part region area process means 7, and thus the part region connection relation plus the partial areas connected to each other by the partial region area are measured via 0 region area process means 8. In such way, the region can be measured via a small-capacity memory device.
