1. An electronic endoscope apparatus comprising:
- an endoscope having a distal end portion in which a solid state image sensor including horizontal and vertical pixels is arranged for generating an image signal;
signal circuit means for driving the solid state image sensor, to cause the same to generate the image signal, processing the image signal output from the solid state image sensor, and for generating a video signal; and
display means including a screen for displaying an endoscopic image corresponding to the video signal output from the signal circuit means, by means of a plurality of horizontal scanning lines,wherein the number of vertical pixels of said solid state image sensor is less than the number of scanning lines displayed on the screen of the display means, andsaid signal circuit means drives the solid state image sensor and processes the image signal in such a manner that all of the image signals obtained from the solid state image sensor are displayed on the screen of the display means.

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.
