ABSTRACT:
An abnormality detecting apparatus comprises a synchronous detecting circuit for detecting a synchronous signal from a video signal outputted from a camera unit, and an abnormality detecting circuit for judging whether or not a first direct current signal level obtained from an input path of said video signal is greater than a predetermined first threshold value, whether or not a second direct current signal level obtained from said input path of said video signal is smaller than a predetermined second threshold value, and whether or not said synchronous signal is detected by said synchronous detecting circuit, and determining that said input path of said video signal is in one of a normal state, an open state, a power connected state, and a ground connected state based on the result of the judgments.
