[Problem to be Solved] When a cable length between a CHU and a CCU varies, images-capture timings of the plural CHUs mismatch. [Solution] In order to match the images-capture timing of the CHU, a phase control circuit in each CCU transfers, to the CHU, a frame pulse signal, a phase of which is advanced by a correction time corresponding to the cable from a time position of beginning of a frame of a reference synchronizing signal input to the CCU. In this way, a timing of the beginning of a frame of a synchronizing signal, which is received by the CHU from a synchronizing signal generation circuit, matches in a case of 1 m transfer, 400 m transfer, and 1 km transfer. Therefore, the images-capture timings of the CHUs can match.
