Abstract: PURPOSE:To efficiently extract individual pattern images by a method wherein the number of picture elements of the individual independent pattern images is counted for each pattern image and, for an inspection, the individual pattern images are selected on the basis of the number of individual counted pattern images. CONSTITUTION:An image data of patterns, under test, of an IC package 1 whose picture has been taken by using a CCD camera 3 is written into an image memory 4. The image memory 4 is an 8-bit memory and has an address composed of (m) lines and (n) rows. The image data of the image memory 4 is read out by a CPU 6 through an address counter 5; the image data is processed; after that, the data is written into a concentration distribution memory 7, a binary-coded image memory 8 and a label memory 9. After this labeling operation, individual areas, i.e., the number of picture images, of individual pattern images 13 are totalized.
