Abstract

PURPOSE: To simplify a test on a complicated pattern by compounding and comparing a pattern of several prescribed test points on a material and pattern picture elements registered previously.
CONSTITUTION: A fixed range of inspected material pattern 1 is picture-taken by TV10, and pattern information on it is binarycoded and then stored in picture memory 2. Then, picture-element recognition circuit 3 checks whether or not a pattern resides at a prescribed recognition point of a pattern in memory 2 and on the basis of this recognition information, several picture-element memories are extracted from picture-element memory group 5 registered previously, thereby compounding 6 patterns. This compound pattern is compared 7 with the contents of memory 2, and consequently points where the both disagree are stored as defective places in memory 8 and then displayed 9.
