ABSTRACT:
Scrap containing copper is discriminated from iron scrap after being pulverized by imaging iron scrap using a color TV camera, treating RGB signals processed by each of the points in the image as a color vector, and discriminating scrap containing copper from iron scrap when the saturation value of the color vector is larger than a predetermined value and the hue angle of the color vector lies within a predetermined range.
