An image capture device comprises an image capture unit which captures an image and a control unit which controls the image capture unit. The image capture device further comprises: a reference clock unit which generates a reference clock and a signal I/O unit which is disposed between the image capture unit and the control unit and which handles input and output of a signal in synchronization with the reference clock which is generated by the reference clock unit. The control unit further comprises: a generator means for generating a plurality of control signals which control the image capture unit and generating extraction timing at which a measurement signal is extracted from the image capture unit a transmission means for transmitting via the signal I/O unit to the image capture unit in synchronization with the reference clock the plurality of control signals which are generated by the generator means a receiving means for receiving via the signal I/O unit in synchronization with the reference clock the measurement signal from the image capture unit and counting the number of times that the measurement signal is received and an extraction means for extracting the measurement signal when the number of times that the measurement signal is received by the receiving means is the extraction timing which is generated by the generator means.
