Abstract

PURPOSE:To detect exactly an existence of an object substance, by flashing each two lighting devices one by one, between which the object substance is placed, and therewith by judging the existence of the subject when each brightness histogram differs one another. CONSTITUTION:When tip parts 7 is lighted solely by a lighting device 8, a shadow a is cast on a zone A and nothing on a zone B. With a TV camera 12 and an image recognition device 13, brightness histograms A1 and B1 of the zones A and B are obtained. thereafter, when the parts 7 is lighted solely by a lighting device 9, a shadow is cast on the zone B and nothing on the zone A. So, another set of brightness histograms A1 and B1 in this case is also obtained. An existence of the parts 7 is identified when there exists differences more than a predetermined extent for both between A1 and A2 and between B1 and B2. Subsequently, the existence of the parts 7 is exactly detected even if a conventional method might detect it wrongly.
