Abstract
In an object recognition device for judging the normality of an object to be recognized, a monitor region including a plurality of monitor points and being represented by one of the monitor points is superimposed of an image produced by video signals obtained from the object. Additionally, the variation of luminance information obtained from the monitor region with respect to reference information is monitored. In a case where the position of the monitor region on the video image of the object becomes unsuitable for normality determination, a correction range is set at and around the monitor point and the setting of the monitor region is updated to one of a plurality of the monitor points having luminance information obtained when the monitor region is moved to one of the plurality of monitor points contained in the correction range, on which the judgement of normality is facilitated.
