A system for determining range and orientation of distant objects such as a ship. By utilizing split imaging the observed height on a video monitor can be accurately determined despite movements of the image on the monitor. The observed ship can be visually identified and the true height determined from reference sources. A better comparison of data indicating the true height compared to observed height permits calculation of the range to the target ship. Split imaging can also be utilized to de...

A video camera comprising an image-forming lens system having an optical axis and a light-beam splitting means capable of splitting an incident light-beam from the image-forming lens system into a primary optical path along the optical axis and leading into a view finder means, and a secondary optical path bent at an angle to the primary optical path and leading into an electrical image-receiving means. There is provided a camera tube in the bent optical path and a view finder in the straight op...

A video cassette with two reels which are arranged in plane-parallel fashion for winding and unwinding a magnetic tape and with a locking mechanism consisting of a pivotal two-armed pawl for each reel which can be slipped on a support. One lever arm engages in a toothed reel flange in the inoperative position of the cassette and the other lever arm rests on the disengaging component of a vertically rotatable release lever. The locking mechanism also includes moulded pre-tensioning arms, the defl...

A video signal processor for effecting frame rate conversion. A number of framestores connected in series receive incoming video signals under the control of a first generator and are available from the respective fieldstores under the control of a second generator. The presence of respective one line delays allow two adjacent lines from the same field to be available for use by respective multipliers and thence to an adder. A comparator determines if significant movement is present and modifies...

Disclosed is a video camera in which the field of view of an automatic focusing device is displayed on an electronic view finder, and the displayed field of view is adjustable in accordance with the object distance and/or the zooming state of the lens system.

Racks and shelves for displaying such objects as video cassette boxes have been arranged so that the boxes have been presented face-on, or spine-on. The invention displays the boxes diagonally so both the spine and a portion of the front face are presented. The disclosed rack is of vacuum formed plastic sheet material having ribs formed diagonally across a platform. The ribs are hollow, being constituted by folds in the sheet material. Dividers are located in the hollow interiors of the ribs. Th...

A video camera capable of taking both still pictures and moving pictures yet having a size and weight substantially the same as a conventional video camera. The automatic aperture of the video camera is used as an aperture and shutter for still picture photographing operations. The lens body has a programmed exposure time control circuit for producing an exposure time control signal, while the camera body has a still control circuit for producing a still control signal which marks the start and ...

A video synthesizer is adapted for connection to the input circuitry of an oscilloscope, and includes sampling and multiplexing circuitry for presentation of a multiplicity of input signals to a single channel of the oscilloscope. The signals are sampled sequentially, and the samples of respective ones of the signals are multiplexed with corresponding reference voltage levels of a voltage divider so as to vertically displace the signals on the face of the oscilloscope. For periodic input signals...

A video component interconnection system includes a single signal conductor video bus serially coupled between each of the video components for conducting video signal between the components. A switch located in series with the video bus separates the continuity of the video bus when it is non-conductive. A shunt switch arrangement coupled to the video bus at its junction with the series switch, applies an impedance substantially equal to the characteristic impedance of the video bus between the...

The invention provides a method of controlling the color of the individual pixels of a digital display with appearance information formed by color information and position information. Each set of color information is applicable to a pair of adjacent pixels, but the position signal may cause the color signal of one pair of pixels to control the color of one pixel of the adjacent pair. Apparatus for practicing the invention includes a storage means capable of storing two sets of appearance inform...
