Resolution - A measure of how closely packed the dots in a bitmapped image are, often expressed in dots per inch (dpi) or lines per inch (lpi). The higher the number, the higher the quality. However, doubling the resolution of an image results in a computer file four times as large, requiring more hard disk space and computer memory to handle the higher quality image. Resolution is also used to describe how close together a computer printer can print dots in an image. Again, the larger the number, the higher the quality. It is important to know the capability of the printer's resolution before scanning an image in order to get enough information to print the best quality.
Super Contrast CRT - Hitachi projection television CRT that is specifically engineered for high-quality HDTV performance. It employs an improved electron gun and high-definition phosphor formulation which produces a bright and highly focused image.
Over-the-air Broadcast (OTA) - Also called Terrestrial Broadcast. The delivery of TV and radio signals, using UHF/VHF frequencies, directly to consumer devices. Broadcasts may be either analog or digital.
Bitmap Graphics - Graphics that are constructed of individual pixels.
Subwoofer - A special loudspeaker system used to reproduce and enhance low frequency performance.
Auto Search Tuning - Initiates the tuner's search until a radio station of sufficient strength has been found. Weak stations are skipped during automatic search.
Auto Exposure Control - Automatically senses the ambient light intensity and adjusts the aperture and shutter speed for optimum exposure or turns the flash on if required. To take a good picture, the camera must allow precisely the correct amount of light to hit the film. This quantity of light can be controlled by making the opening at the lens wider or narrower or by controlling the amount of time that the shutter remains open to allow light to pass through. Inexpensive cameras may have no adjustments at all. Many cameras control the size of the lens opening, called the diaphragm or iris. They provide a wide opening for low sensitivity films, or low light conditions, and small openings for high sensitivity films or bright light conditions.
