Patent ID: 7456863

Claim:
An imaging apparatus comprising at least one camera device that photographs an object, a signal processor that receives a video signal from the camera device, and a connection cable connecting the camera device and the signal processor, the camera device comprising: a first phase controller that compares the phase of a synchronization signal transmitted from the signal processor with the phase of an internal signal generated by the camera device, and that controls the phase of the internal signal so as to be synchronized with the phase of the synchronization signal; a video synchronization signal generator that generates a video synchronization signal that is a synchronization signal for the video signal based on the internal signal whose phase is synchronized with the phase of the synchronization signal transmitted from the signal processor; and a signal transmitter that transmits at least the video signal via the connection cable, the signal processor comprising a second phase controller that compares the phase of the video synchronization signal with the phase of the synchronization signal transmitted from the signal processor, and that controls the phase of the video synchronization signal so as to be synchronized with the phase of the synchronization signal.
