ABSTRACT:
An image processing system adapted to measure tool wear by imaging the worn portion of a tool with an ITV to produce images thereof together with surrounding portions, comparing the brightness distributions of the images with each other, and carrying out image processing by use of a brightness threshold value set at a boundary between a region wherein variation of the brightness distribution occurs and a region wherein it does not occur.
