Abstract
An endoscope system with an endoscope, a TV monitor, and a peripheral device separate from the endoscope and the TV monitor is provided. The endoscope includes an objective optical system and an image pickup device that converts an image formed by the objective optical system into a video signal which can be indicated in the TV monitor. The endoscope also includes a signal generator that generates a control signal to be supplied to the peripheral device so as to control the peripheral device. Additionally, the endoscope includes a transmitter that transmits the video signal to the TV monitor while no control signal is generated by the signal generator. The transmitter also transmits, as a radio signal, both the video signal and the control signal to the TV monitor and the peripheral device upon the control signal being generated by the signal generator. The endoscope also includes a signal adder that adds the control signal to a blanking interval of the video signal to output the video signal added with the control signal to the transmitter.
