Abstract:
An electronic endoscope system, comprising:an elongated scope having a solid state image sensor provided at a distal end thereof, to generate image-pixel signals; a video-signal processing unit, to which said elongated scope is detachably connected at a proximal end thereof, to produce a video signal on the basis of the image-pixel signals; a monitor that reproduces an image in accordance with the video signal; a displaying-size changer that changes a size of a displaying-area of the reproduced image on a screen of said monitor to another size; a pointer-image generator that generates a pointer image on the screen of said monitor; and a pointer-image controller that controls a shifting of said pointer image on the screen of said monitor, wherein said pointer image controller includes a pointer-image-position converter that converts a position of said pointer image on the screen of said monitor in accordance with the size change of the displaying-area of the reproduced image on the screen of said monitor, such that two positions, indicated by said pointer image on two-sized display-areas, correspond to each other.
