Abstract
An electronic endoscope apparatus having an endoscope with a distal portion containing a solid-state image sensor. The endoscope has a connector section. A frequency divider is provided within this connector section. A video processor is coupled to the endoscope. The video processor outputs a constant-frequency signal, which is supplied to the frequency divider. The frequency divider divides this signal with a frequency division rate corresponding to the number of pixels which the image sensor has.
