An object recognition device for judging the normality of an object (15) provides a monitor region including a plurality of monitor points superimposed on an image produced by video signal (VD) obtained from the object. Variation in the luminance information obtained from the image with respect to a reference information from the monitor region 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 point is updated to another one of a plurality of monitor points in the monitor region. The luminance information obtained when the monitor region is moved to the other one of the plurality of monitor points contained in the correction range facilitates the judgement of normality. |
