摘要:
An endoscope system 1 includes an image pickup section 12 provided with an image sensor 14 and configured to obtain an examination image a cable 13 that transmits the examination image and a processor 3 that receives the examination image, performs image processing, and displays the processed image. The processor 3 includes: a cable driver 21 that applies a voltage higher than an input voltage standard of the image pickup section 12 so as to compensate for attenuation of a high-frequency signal caused by the cable 13 and outputs a clock signal for driving the image pickup section 12 a peaking circuit 22 that performs waveform correction of the clock signal and a DC level limiting circuit 23 configured to limit, when a clock signal inputted from the first peaking circuit 22 is switched to a DC voltage, an amplitude level of the DC voltage so as not to exceed a level of the input voltage standard of the image pickup section 12.
