An electronic endoscope system, which is adapted to observe a fluorescence image of autofluorescence emitted from a body cavity wall irradiated with excitation light as well as a normal image of the body cavity wall illuminated with white light on a display device, includes a display controller whereby the aspect ratio of at least one of a plurality of images to display is converted so that the plurality of images are displayed in conformity with the shape of a display area of the display device when the plurality of images including the normal image and the fluorescence image are displayed on the display device. In the electronic endoscope system, the display controller converts the aspect ratio of at least one of the plurality of images by cutting both horizontal ends of the image to convert.
