PROGRAMMABILE DALL'OPERATORE. APPARECCHIATURA DI ISPEZIONE

Programmable video inspection apparatus. The invention includes a camera for viewing an object of interest, the camera presenting a video signal to both a monitor for operator viewing and a digitizer. The digitizer generates an array of digitized pixels from the video signal and stores the same in a memory. A processing unit compares specific groupings of pixels known as windows against predetermined values to determine the acceptability of the object. The preselected values may he generated by the operator by viewing an object of known quality on the monitor and by selecting the windows of interest for such objects by means of a control panel. The operator can define the windows of interest as to position and size, as well as with respect to the test to be conducted upon such window, the threshold levels associated with the window, and the minimum number of pixels within the window which must satisfy the test.
