Abstract:
An electronic endoscope comprising:a video-scope having an image sensor provided at a distal end thereof, adapted to form an object image and generate image-pixel signals corresponding to said object image;a video-processor adapted to process said image-pixel signals so as to generate video signals, to which a proximal end of said video-scope and a monitor for displaying said object image are connected respectively;a character and mark generation controller adapted to generate character signals and indicator-mark signals, and further adapted to feed said character signals and said indicator-mark signals with said video signals to said monitor, such that character information and an indicator-mark are respectively displayed at a position on a screen of said monitor with said object image; andan image-area changer adapted to change a size of an image-area of said object image displayed on the screen of said monitor to another size, whereby said object image is selectively displayed within one of plural image-areas on the screen in accordance with a size-change of the image-area,wherein said character and mark generation controller includes a display-position adjuster adapted to determine display-positions of said character information and said indicator-mark on the basis of a reference table, in which a correspondence relationship between each of said image-areas and each of said display-positions of said character information and said indicator-mark is indicated, whereby said character information and said indicator-mark are respectively displayed at said determined display-positions in accordance with the size-change of said image-area.
