Abstract
An electronic endoscope apparatus including an endoscope having a distal end portion in which a solid state image sensor is arranged, a signal-processing circuit for processing an image signal output from the solid state image sensor, and a monitor for displaying, as an endoscopic image, a video signal supplied from the signal-processing circuit. The number of vertical pixels of the solid state image sensor is less than the number of scanning lines displayed on the screen of the monitor, whereby all of the image signals supplied from the solid state image sensor are utilized for the image displayed on the monitor.
