Patent ID: 7275005

Claim:
A method for inspecting an appearance of a plurality of worked products held by an inspection target sheet, the method comprising: conducting image processing at a first location to obtain image-processed data; and conducting defect detection at a second location remote from the first location using the image-processed data obtained during image processing; wherein: conducting image processing comprises: imaging each worked product held by the inspection target sheet to obtain image data; retrieving the image data relating to each worked product; comparing the retrieved image data with basic image data prepared in advance of image processing to identify a defect candidate part based on a predetermined condition; and extracting position data and image data relating to the defect candidate part as image-processed data; conducting defect detection comprises: displaying an image of the defect candidate part based on the image-processed data to urge an operator to determine whether the defect candidate part is a defect part; and creating detection result data including position data for each defect part based on the operator's determination and the image-processed data; and wherein: each of the plurality of worked products is either a lead frame for a semiconductor package or a spring member for a hard disk drive.
