Abstract
An abnormality supervising system compares an input picture with a previously stored reference picture having no abnormality, provides a compared picture signal to an abnormality discrimination means having preliminarily stored information for abnormality discrimination, and, upon presence of an abnormality, operates an output means for informing operation, whereby the abnormality discrimination means can effectively attain the abnormality discrimination on the basis of the preliminarily stored information, in a highly reliable manner.
