A surface position detection apparatus of this invention includes a position detection section having a plurality of electrodes opposing the object surface to be measured, and a measurement device for selecting at least one electrode of the plurality of electrodes in accordance with the shape of the object surface, supplying an AC current to the selected electrode, and measuring the current flowing to the electrode, thereby measuring the distance between the electrode and object surface.

A portable camera with integral printer device, the camera including a digital image capture device for the capturing of digital images; an integral programming language interpreter connected to the digital image capture device for the manipulation of the digital image; and a script input device for inputting a self documenting program script for the manipulation of the digital image to produce visible alterations thereof The script input device comprises a card reader for optically reading a sc...

A camera display system comprises circuit sections and a driving section disposed in a camera, a display section having display patterns each corresponding to an error detected in one of the circuit sections or the driving section, and a control section for controlling the display section and the circuit sections. When an error is detected in one of the circuit sections or the driving section of the camera, the control section controls the display section to display the detected error by turning...

A time-sharing drive apparatus for a camera having a plurality of motors includes a motor drive control system which alternately drives the motors in a time-sharing control. When the camera includes a zoom lens provided with a first stationary lens group, a second movable lens group and a third movable lens group, the motors are composed of a first motor which opens and closes a diaphragm of the zoom lens, a second motor which moves the second lens group, and a third motor which drives the third...

There is disclosed an arrangement which has a projection means (LEDs) for projecting a light, a display means (mirror, finder view field range and the like) for guiding the light projected by the projection means to a predetermined display portion to display an index in the display portion, a variable means (masks, motor, decentring axis and the like) for periodically changing a projecting direction of the light of the projection means, and a control means (mask position detection circuit, contr...

A remote camera positioning and control system is disclosed that permits a sole operator to use and support a camera out of arm's reach without external structural or personnel support. Various features of such a remote camera positioning and control system are disclosed. The positioner can include one or more beam modules having cross-sectional flexural rigidity that varies along the length of the beam module(s) by use, for example, of stiffening longerons, anchoring braces and relatively low d...

A camera in which the ratio of an object to the photographing frame can be set comprises a varifocal lens in which the in-focus position is changed in accordance with the change in the focal lens and a focusing lens for correcting the focus by the varifocal lens. The size of the object is set to the desired size by using the varifocal lens, and thereafter the deviation of the in-focus point is controlled by the focusing lens. Since the zooming is carried out by using a varifocal lens, a camera c...

An electronic device has a plurality of prestored limit times that define a time period of non-use, after which the electronic device will enter an energy-saving state. A different one of the plurality of limit times can be selected for different operating modes of the electronic device. Thus, when the electronic device is switched between different modes, different limit times, which define the duration of the non-use period prior to entering the energy-saving state, will take effect. Additiona...

A continuous motion picture system for operation in conjunction with a vehicle carrying passengers along a running path is disclosed. The system has screen boxes having a screen and a projector for displaying a still picture for a duration of a display period. The screen boxes are serially disposed at intervals of a given distance provided in place along the running path of the vehicle. The system also has a device for supplying picture signals of a sequence of fames, which depict motion when vi...
