An image display controlling unit controls to display a standard image and a dummy image. The standard image is an image that has been previously decided by the user. The dummy image looks like the standard image but the standard image and the dummy image has differences that only the user can identify and that can not be identified from a distance. The user selects a predetermined section of the standard image and selects a dummy section from the dummy image. A password is input based on information corresponding to the predetermined section of the standard image and information corresponding to the dummy section of the dummy image is neglected.

A rangefinder mechanism is shown in which the scanning mirror has been replaced with a movable scanning optic. The automatic rangefinder system includes a pair of optical paths, one a reference path and the other a scanned path, which are lead to impinge upon a photosensitive surface for comparison purposes. The output of the photosensitive surface is used to adjust the main lens of the camera. The range of the movable optic is coordinated with the position of the main lens of the camera as feedback and adjustment of the rangefinder.

Automatic focus adjusting device

An automatic rangefinding optical system for a camera includes optics conted for movement subject to the operative zooming main lens. The rangefinding system has an automatic focusing device which generates a pulse when separate objective images from two optical system paths coincide. Zooming the rangefinder along the two optical system paths gives more precise automatic focusing of the subject by optically modifying the objective images according to the zoom position of the main lens.

Rangefinding optical system

A rangefinder mechanism is shown in which the scanning mirror has been reced with a movable scanning optic. The automatic rangefinder system includes a pair of optical paths one a reference path and the other a scanned path which are led to impinge upon a photosensitive surface for comparison purposes. The output of the photosensitive surface is used to adjust the main lens of the camera. Disposed in front of the movable optic is another optical movable relative thereto to coordinate with the position of the main lens of the camera as feedback and adjust the rangefinder system.
