Abstract: A communication system includes: a first signal line; a second signal line; a first signal line selection portion and a second signal line selection portion for selecting either one of the first signal line and the second signal line so as to be effective as the serial data; and a signal control portion for outputting a signal direction switching signal for controlling a selecting operation. The first signal line selection portion includes a first OR circuit and a first three-state buffer circuit provided on the first signal line, and a first buffer provided on the second signal line, and the second signal line selection portion includes a second OR circuit and a second three-state buffer circuit provided on the second signal line, a second buffer provided on the first signal line, and an inverter circuit provided between a terminal of the signal control portion and the second OR circuit.

Abstract: An imaging system includes: a light source configured to emit illumination light; an imager configured to store an electric charge corresponding to an amount of received light and read out the stored electric charge as a signal value by using a rolling shutter method; a frequency detector configured to detect a vibrational frequency of a predetermined site of a subject; and an illumination controller configured to control emission of the illumination light during a readout period of the signal value. The illumination controller is configured to set a phrase for an emission timing of the illumination light in an exposure period during which the imager stores the electric charge to be an identical phase at the frequency in each frame, and refer to respective phases set in exposure periods of chronologically adjacent frames to set an emission timing of the illumination light in the readout period.
