Title: IMAGING DEVICE AND ENDOSCOPE SYSTEM
Abstract:
This imaging device transmits an imaging output generated by time division multiplexing a reference voltage signal and an imaging signal, and is provided with: a first sample-and-hold circuit for sampling and holding the imaging signal; a second sample-and-hold circuit for sampling and holding the reference voltage signal; an output selection unit for performing switching and selection between the imaging signal inputted from the first sample-and-hold circuit and the reference voltage signal inputted from the second sample-and-hold circuit, and outputting the selected one as the imaging output; and a timing control unit for controlling the timing of switching and selection by the output selection unit. The timing control unit determines the timing of switching and selection by the output selection unit such that the average transmission cycle of the reference voltage signal is longer than the average transmission cycle of the imaging signal.
