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.
Red Eye Reduction - Some cameras with red eye reduction have a small bright red light, located on the front of the camera, that turns on when the shutter button is first depressed. The eye's iris will close in response to this light, making the opening in the eye smaller. The regular cameraflash then fires with less chance of being reflected back from the rear of the eye.
Sharpening - A picture enhancement making the image have more distinct borders, areas, lines or tones.
Dot - Dots make up an image in color separations or halftones. Halftone dots will have a fixed density but have variable size (amplitude modulation).
Must-carry - This refers to the legal obligation of cable companies to carry analog or digital signals of over-the-air local broadcasters.
Aspect Adjustment Capability - A feature of various 'image' devices including camcorder, digital still and DVD. It lets you choose from display modes, depending on the format of the received signal and your viewing preference. The Zoom Mode allows you to enlarge the picture uniformly to full screen width and then reposition the picture vertically.
PVP-UAB - Protected Video Path User-Accessible Bus. Encrypts video content as it passes over the PCI Express bus from the high-def disc to prevent other PCI Express devices from intercepting the video stream.
