Megapixel - A measure of resolution that reflects the ability of a digital camera to record detail. The more megapixels a camera has, the more detail its images can contain and the more they can be enlarged without losing clarity. More megapixels aren't always necessary, however. For more information see DCHQ's First Time Buyer's Guide.
RAM - Random Access Memory. Temporary storage for computer applications.
Camcorder - Video camera and video recorder in one unit. Very portable, compact and convenient.
Burst mode - A special mode for shooting a sequence of images in rapid succession. Also known as continuous.
35mm equivalency - What a digital lens would be equivalent to in terms of a 35mm film SLR camera. Used as a standard for discussing the field of view and magnification power of a lens. In 35mm equivalency, lenses over 50mm are telephoto, whereas lenses below 50mm are wide-angle or fisheye lens. In a digital SLR, a mirror placed in front of the focal plane (where the image sensor sits) bounces the light that comes from the lens upward into a prism and then out the eyepiece. When you press the shutter button, the mirror flips up out of the way so the light can pass to the focal plane.
S-video - Also called Y/C, this two-wire standard keeps the color separate from the intensity signal, and thus avoids the overlapping sideband problem of composite signals. (Converting an NTSC signal to S-video gains you nothing since what was lost cannot be recreated.) - Although the quality of S-video is close to component video, S-video cannot transport anything better than 480i.
Palm, Inc. - Makes the Palm OS and the line of Palm handheld devices and accessories. Palm, Inc. split from its parent company, 3Com, early in 2000.
