An endoscope system has an electronic endoscope with a solid-state image sensor, a processor device, and an option circuit board detachably connected to the processor device. The electronic endoscope drives the solid-state image sensor based on a clock signal correspondingly to the number of pixels of the solid-state image sensor, and captures images. The processor device generates a first video signal from an image signal. The option circuit board has a measurement pulse generator for generating measurement pulses, a gate pulse generator for generating a gate pulse, a pulse counter for counting the number of the measurement pulses during outputting the gate pulse, and a judgment circuit for obtaining the number of pixels from a count value of the pulse counter. The option circuit board converts the first video signal into a second video signal in consideration of the number of pixels to display the images on a PC monitor.
An option circuit board detachably connected to a processor device and having a signal processing circuit, said processor device producing a first video signal from an image signal outputted from a solid-state image sensor contained in an electronic endoscope, said solid-state image sensor being driven by a clock signal whose frequency corresponds to the number of pixels thereof, said signal processing circuit converting said first video signal into a second video signal in consideration of said number of pixels of said solid-state image sensor to display an image on external equipment, said option circuit board comprising:
