Abstract: In an endoscope system, an imaging device is electrically connected to a signal line and is configured to output a video signal to the signal line. A receiver circuit is electrically connected to the signal line and is configured to receive the video signal. A noise detection circuit is configured to detect that noise having a higher frequency than a frequency of the video signal is mixed into the video signal. A filter circuit has a function of reducing the noise included in the video signal. An imaging control circuit is configured to set a signal-output time per one pixel of the imaging device to a second set time longer than a first set time and a filter control circuit is configured to turn on the function of the filter circuit when the noise is detected by the noise detection circuit.
