Abstract: The image monitoring apparatus (10) has an image acquiring unit (15), an image processing unit (16) and a determining unit (17). The image acquiring unit (15) continuously acquires a peripheral image. The image acquiring unit (15) superimposes a periodically changing signal on a predetermined position of the peripheral image. The image processing unit (16) treats the peripheral image superimposed with the signal with a predetermined image processing. The determining unit (17) determines a failure of the image processing unit based on a presence or absence of a periodic change in the superimposed signal on the peripheral image treated with the predetermined image processing.
