PROBLEM TO BE SOLVED: To achieve external synchronization automatically without any phase adjustment, and to extend the transmission line between an imaging apparatus and an imaging control unit without any limitation. SOLUTION: An imaging system comprises the imaging apparatus 100 that photographs an object and generates an image signal, and the imaging control unit 110 connected to the imaging apparatus via the transmission line. The imaging apparatus has a vertical synchronization generation circuit 200 for generating an internal vertical synchronization signal utilized for imaging in the imaging apparatus. The imaging control unit has: a delay measurement circuit 210 for measuring the amount of delay between a test signal outputted to the imaging apparatus and the test signal outputted to the imaging apparatus, and going back the transmission line; and a vertical synchronization phase advancing circuit 214 that advances the phase of an external vertical synchronization signal by the amount of delay for outputting to the imaging apparatus. The vertical synchronization generation circuit is reset by a signal outputted from the vertical synchronization phase advancing circuit. COPYRIGHT: (C)2007,JPO&INPIT
