ABSTRACT:
An electronic endoscope apparatus whereby the position of the tip part of an insertable part inserted into a body cavity is confirmed from outside the body with the transmission out of the body from within the body cavity of a light emitted from an illuminating window provided in the tip part. It comprises an imaging apparatus for creating an image of an inspected part obtained from an observing window provided in the tip part of the insertable part and for converting this image to an electric signal and outputting it, an illuminating apparatus for feeding an illuminating light to the imaging apparatus and for adjusting the brightness of the illuminating light when a confirming signal directing to confirm the position of the tip part of the insertable part is input, a signal processing apparatus for processing the electric signal obtained from the imaging apparatus, outputting a video signal which is a normal observing picture image signal of a moving picture in case the confirming signal is not input and outputting a video signal which is a picture image signal different from the ordinary observing picture image signal in case the confirming signal is input, and a displaying apparatus for receiving the video signal output by the signal processing apparatus and displaying the picture image of the inspected part.
