Abstract:
An electronic endoscope having a video-scope with an image sensor, a video-processor and a display, said video-scope and said display being connected to said video-processor, said electronic endoscope comprising:an image forming processor that forms a display subject image for display on the basis of an all-pixel subject image, which is formed on said image sensor and composed of substantially all pixels in said image sensor; a signal processor that generates video signals on the basis of image-pixel signals, which correspond to said display subject image, and outputs said video signals to said display; and a display-state changing processor that changes a display-state from a normal-display to a magnified-display and from the magnified-display to the normal-display, wherein said image forming processor forms a normal-display subject image composed of a smaller number of pixels than that of said all-pixel subject image as said display subject image during the normal-display, an image-resolution of said normal-display subject image being different from that of said all-pixel subject image, and wherein said image forming processor forms a magnified-display subject image composed of pixels arranged within a part-area of said all-pixel subject image as said display subject image during the magnified-display.
