Term
Beam Splitter
Definition
Compact internal optical system of prisms within a television camera that seperates white light into the three primary colors; red, green and blue...also called prism block
Term
Brightness
Definition
the color attribute that determines how dark or light a color appears on the monochrome television screen or how much light the color reflects. Also, called lighthness and or luminence
Term
Camcorder
Definition
A portable camera with the video recorder or some other recording device built into it to form a single unit
Term
Camera Chain Unit
Definition
Equiptment, seperate from the camera head, tht contains various video controls, including color fidelity, color balance, contrast, and brightness. The CCU enables the video operator operator to adjust the camera picture during a show
Term
Charge-Coupled Device (CCD)
Definition
The imaging sensor in a television camera. It consists of horizontal and vertical rows of tiny image-sensing elements, called pixels, that translate the optical (light) image into an electrical charge that eventually bc the video signal
Term
CMOS
Definition
A camera imaging sensor similar to a CCD but which operates on a different technology. It translates light into an electronic video charge that eventually becomes the video signal.
Term
Contrast Ratio
Definition
The difference bw the brightest and the darkest portions in the picture (often measured by reflected light in foot-candles).
Term
Digital Cinerma Camera
Definition
A high-definition television camera that has a native frame rate of 24 frames per second and a variable frame rate for slow and accelerated motion. Most digital cameras use high-quality CCDs or CMOS sensors, state-of-the-art lenses, and high-def viewfinders
Term
EFP camera
Definition
High-Quality poratble,shoulder mounted field production camera that must be connected to an external video recorder
Term
ENG/EFP Camcorder
Definition
High-Quality portable field production camera with the recording device built-in.
Term
High-definition Video
Definition
A recording system that produces images of the same resolution as high-definition television with equiptment that is similar to standard digital video camcorders. The video signals are much more compressed than those of HDTV, however, which results in lower overall video quality.
Term
High-Definition Television Cameras
Definition
Video camera that delivers pictures of superior resolution, color fidelity, and light-and-dark contrast; uses high-quality imaging sensors and lenses
Term
Hue
Definition
One of the three basic color attributesl hue is the color itself-red, green, yellow and so on
Term
Imaging Device
Definition
The imaging element in a television camera. Its sensor (CCD or CMOS) transduces light into electric energy that becomes the video signal. Also called camera pickup device, chip and sensor
Term
Pixel
Definition
Short for picture element. A single imaging element that can be identified by a computer. The more pixels per picture area, the higher the picture quality. The light-sensitive elements on a CCD that contain a charge.
Term
Resolution
Definition
The measurement of picture detail, expressed in the number of pixels per scanning line and the number of visible scanning lines. Resolution is influenced by the imaging device, the lens, and the television set that shows the camera picture. Often used synonymously with definition.
Term
Saturation
Definition
The color attribute that describes a color's richness or stregnth.
Term
Sensor
Definition
The CCD or CMOS imaging device in a video camera.
Term
Standard Television (STV)
Definition
A system based on on the NTSC scanning system of 535 (480 visible) interlaced lines
Term
Studio Camera
Definition
High-Quality Camera with a large zoon-lens that cannot be manuevered properly without the aid of a pedestal or some other camera mount
Term
Sync Generator
Definition
Part of the Camera Chain; produces an electronic synchronization signal
Term
White Balance
Definition
The adjustments of color circuits in the camera to produce a white color in lighting of various color temperatures (relative reddishness or bluishness of white light)
Term
Three main parts of the computer
Definition
lens, camera and the viewfinder
Term
Camera Control Unit
Definition
setup and control of a studio camera
Term
Genlock
Definition
provides a general synchroniazation pulse called a house sync-keeps everything sychronized
Term
Gain
Definition
tricks the cameras sensors into believing that they are getting more light than they actually recieve from the lens
Term
Electronic Shutter
Definition
the faster the object moves the faster the shutter should be, but you need more light with a fast shutter
Term
Luminance Channel
Definition
Y Channe, us responsible for the brightness info of the picture
Term
Chromiance Channel
Definition
C channel; transports all of the hue attributes
