Abstract: An endoscope processor comprising a touch-panel monitor, a location detector, a touch-panel image generator, and a location-changer, is provided. The endoscope processor displays an image of a target area with enlargement on a monitor. The target area is a part of a captured entire image. The location detector detects an input location. The input location is a location where the user's input operation is done on the touch-panel monitor. The touch-panel image generator orders a target-area location window to be displayed on the touch-panel monitor. The target-area location window indicates the location of the target area in the entire image. The location-changer changes the location of the target area based on the input location detected by the location detector when the target-area location window is displayed.

Abstract: A lighting apparatus includes a plurality of light sources, and a light-source controller. The light-source controller controls the plurality of light sources so that at least one light source in the plurality of light sources can emit assisting light to form contrasts of luminance on a photographic subject, and so that the light sources can simultaneously emit illuminating light to illuminate the photographic subject uniformly. And a photographing apparatus includes the lighting apparatus, a line sensor, and a distance measurer. The line sensor forms image signals corresponding to an image of the photographic subject by receiving the reflected light of the assisting light or the illuminating light reflected by the photographic subject. The distance measurer measures a distance to the subject based on the image signals formed by the line sensor.
