LPI (Lines Per Inch) - See "Line Screen"
Auto Program Tuning - This feature will automatically store 30 preset stations in a TV's or VCR's memory.
Digital - Information or data that exists as numerical values (1 or 0) based on a binary coding system.
Resolution - The level of resolution directly affects picture quality. The higher the resolution, the more picture detail there is. Many things affect picture quality, including number of bits, pixel count, format, receiver quality, cameras, lenses and lighting used for live or taped programming. Resolution is measured by the number of pixels displayed. One of the high-definition picture formats is composed of 1080 active lines, and each line is composed of 1920 active pixels. Therefore, each frame has over 2 million (1080x1920=2,073,600) color pixels creating the image. By way of contrast, today's typical analog television is roughly equivalent to 480 active lines, with each line holding about 440 pixels. So, each frame has a little over 200,000 color pixels in use creating the image.
Leaderless Thrusting - A unique capability of APS cassette which enables the active light lock door to be opened and the film strip to be thrust into the camera body for loading.
LFE - (Low Frequency Effects) - Sub-woofer. The 6th channel in a 5.1 channel system.
Cropping factor - Many digital SLRs use an image sensor that is smaller than 35mm film. If you attach a lens to one of these cameras, its 35mm equivalency will be multiplied by the cropping factor-a manufacturer's specification. For example, if your digital SLR has a cropping factor of 1.6x, then a 50mm lens mounted on your camera will have a 35mm equivalency of 80mm. That is, the 50mm lens will yield the same field of view as an 80mm lens on a 35mm camera.
