ABSTRACT:
A visual inspection system for inspecting pharmaceutical tablets. The system comprises a photoelectric detection means for detecting the light intensity within an inspection area on a tablet and for generating a detection signal which varies with that light intensity. The system also comprises a signal processing means for comparing the detection signal to a predetermined standard in order to generate a selection signal and a transducer means which is responsive to the selection signal. A separation means separates the tablets into at least two groups in accordance with the selection signal. Yet another aspect of this invention is a method for inspecting the surface of pharmaceutical tablets using the above-described vision inspection system.
