ENDOSCOPE WITH HIGH FREQUENCY ACCESSORY AND REDUCED VIDEO INTERFERENCE

摘要

An endoscope incorporating a solid state image pickup element for picking-up optical images of an object under observation, and an accessory means having a high frequency oscillator, is able to perform imaging and an accessory function without mutual interference due to high frequency noise from the accessory means oscillator affecting the imaging signals. The output of high frequency oscillation in the accessory means is inhibited during a signal reading period of the image pickup element by a control pulse sychronized with the application of clock signals to the image pickup element.
