Image device for synchronizing timing of imaging by first and second image sensors, and endoscopic device

An endoscopic device comprising:

• an insertion unit that has an elongated shape and is configured to be inserted into a living body;
• first and second image sensors configured to receive light and to perform photoelectric conversion on the received light to generate electric signals;
• a first communication controller configured to be connected to the first image sensor to perform communication with the first image sensor and to control the communication to perform operating control on the first image sensor;
• a first clock generator configured to generate a first clock signal that is a reference for operation of the first communication controller;
• a second communication controller configured to be connected to the second image sensor to perform communication with the second image sensor and to control the communication to perform operating control on the second image sensor;
• a second clock generator configured to generate a second clock signal that is a reference for operation of the second communication controller;
• a reference synchronization signal generator configured to generate a reference synchronization signal;
• and
• an imaging synchronization signal generator configured to:
• generate an imaging synchronization signal;
• and
• output the imaging synchronization signal to the first and second communication controllers at a timing when a predetermined period of time has elapsed from a reference timing based on the reference synchronization signal,
• wherein the first and second communication controllers are configured to determine the timings of imaging by the first and second image sensors using the imaging synchronization signal output from the imaging synchronization signal generator as a trigger to perform synchronization control communications for synchronizing timings of imaging by the first and second image sensors.
