Dual image video inspection apparatus

Abstract: A video inspection system includes first and second video cameras (36 and 48) mounted along a parallel axes. A lighting array (16) is pulsed, and resultant light is reflected from a specimen to both cameras. Orientation of the specimen is determined in accordance with an image generated from a first camera (36). This data is used to isolate a selected portion of the specimen for analysis by an image generated from the second camera (48).

Remote control and camera combination

Abstract: A remote control camera apparatus comprising a video camera or motion picture camera mounted on a tripod, and the camera having a first servo motor to rotate the camera throughout a 360 degree horizontal arc, and a second servo motor to pivot the camera throughout a 180 degree vertical arc. Each servo motor is controlled by an electrical circuit having a receiver to receive radio frequency signals transmitted by a remote control transmitter with said radio frequency signals including an operating control signal to signal each of the servo motors when to start, when to stop, and in what direction to rotate. A laser transmitter, capable of being turned on and off by the remote transmitter, is mounted on or adjacent to the camera to direct a visible laser beam parallel to and slightly above the axis of the camera lens so that the visible laser beam hits slightly above and in line with the center of the area the camera lens is focused on. The laser transmitter enables a person manipulating a camera or plurality of cameras from a remote location to see when each camera is focused on the subject to be shown in the picture. After the camera is focused on the subject, the remote control transmitter turns off the laser beam and turns on the camera until the shooting is complete whereupon the remote transmitter turns off the camera.

Video light apparatus turned-on selectively in a standby-mode of a video camera

Abstract: A video camera apparatus for use in a video camera or a video tape recorder having a built-in type camera in which a video light apparatus is detachably mounted to the body of the video camera, includes a circuit whereby the video light apparatus is automatically turned ON or OFF when the video camera apparatus is in a standby mode in response to a remote control signal, so that the video camera apparatus is easy to use and the video light apparatus can be operated for a longer period of time.

Video camera apparatus

Abstract: A video camera apparatus, for example a video camera or a video tape recorder having a built-in type camera, has a video light apparatus (2) detachably mounted to a video camera body (1), and includes a circuit (48, 48a) whereby the video light apparatus (2) is automatically turned ON or OFF when the video camera apparatus is in a standby mode in response to a remote control signal, so that the video camera apparatus is easy to use and the video light apparatus can be operated for a longer period of time.

Low-light-level color camera with one CCD

Abstract: For full swing commercially available 1/2" and 2/3" imaging sensors in standard video cameras call for an illumination density of approximately 0.5 to 1.0 lx at the input. Improved sensitivities can be achieved by use of image intensifier tubes, coupled to the CCD either fiberoptically or by relay lens. Such configurations are wellknown at black and white low light level TV cameras. Three-channel color cameras with three CCDs have to be equipped with three image intensifier tubes intensifying each of the color component images (RGB) absolutely free of geometric distortions. Such 3-channel low light level cameras are complex in design and expensive. The paper presents a low light level CCD color camera with only one chip and only one image intensifier tube with an excellent cost/performance ratio. An absolutely distortion-free proximity focus image intensifier diode PROXIFIER R of high resolution with a color stripe filter beneath its photocathode is fiberoptically coupled to a CCD with such a precision that the position of the filter-stripes coincides with that of the vertical pixel rows of the CCD.

Video camera system with audio switching circuit

Abstract: A video camera system is composed of a camera head unit having an imager and a microphone, a camera control unit connected to the camera head unit through a coaxial cable for controlling the camera head unit, and a microphone for transmitting an output signal through the coaxial cable to the camera control unit. According to this video camera system, a noise component entered the camera control unit from the camera head unit can be reduced, two communication systems can be independently utilized, and a noise component in the coaxial cable can be reduced considerably. In addition, it becomes possible to widen a dynamic range.

Studio CCD camera technology

Abstract: The development of television cameras has been closely linked to that of the actual pick-up devices used. The recent introduction of CCD pick-up devices has had a profound influence on the design, performance and operation of portable television cameras. Now, with high resolution, high performance CCD devices becoming available, studio cameras can be produced which meet the industry's performance requirements, while exploiting the advantages of CCDs. The design of the camera head, control systems, and operational facilities are all influenced by this new pick-up device.

Important considerations on the use of an integrating focal plane array camera in an optical recognition system

Abstract: Two cameras used as output transducers in a time-sequenced templet-matching optical correction system are compared. One camera, a charge-injection device (CID) camera, is equipped with an image intensifier, automatic gain control (AGC), and a standard video output, while the second camera is a charge-coupled device (CCD) camera without an intensifier or AGC but with a computer interface custom-designed to use the camera's digital output. The cameras are used at the output of the optical correlator in order to integrate high frame-rate time-sequenced output correlation responses derived from binary phase-only filters. It is concluded that an image intensifier is the most important feature to have in a CCD or CID camera because the use of it results in a shorter integration time.

Video camera adaptor

Abstract: (57) An adaptor affixing a video camera to a film camera. The adaptor permits the transmission of the Image formed on the focusing screen of the latter to reach the former In a correct loft-right and up-down orientation. For this purpose, it utilizes a mirror which, in one position, transmits the Image to the video carriera, In the other, It permits the viewing of the image on the film camera's focusing screen with or without magnificatian. Nonatheoless, it permits visual and manual access to the normal controls of the camera. A shield prevents the access of light not from the film camera's image to the video camera for a sharper and clearer image. The adaptor attaches to the usual coupling devices of the film camera which generally permits the affixing of photographic accessories. To permit a more compact system, the adaptor bends the light path from the image screen to the video camera through an angle greater than 90 degrees but not greater than 180 degrees. For a single lens reflex camera, this angle may amount to 130 degrees. For a view camera, the light path bends 180 degrees.
