124AppendixesAF (Auto Focus)A system that automatically focuses the camcorder lens on the subject. Your camcorderuses the contrast to focus automatically.ApertureThe aperture controls the amount of light that reaches the camcorder’s sensor.Camcorder shake (Blur)If the camcorder is moved while the shutter is open, the entire image may appear blurred.This occurs more often when the shutter speed is slow. Prevent camcorder shake byraising the sensitivity, using a faster shutter speed. Alternately, use a tripod, the DIS or OISfunction to stabilize the camcorder.CompositionComposition in photography means arranging objects in a photo. Usually, abiding by therule of thirds leads to a good composition.Complementary Metal-Oxide-Semiconductor (CMOS)CMOS is an image sensor producing images approaching the quality of CCD (chargecoupled device) sensors. It consumes less power, meaning a longer battery life on yourcamcorder.Digital zoomA feature that artificially increases the amount of zoom available with zoom lens (Opticalzoom). When using the Digital zoom, the image quality will deteriorate as the magnificationincreases.Effective Pixel CountUnlike the total pixel count, this is the actual number of pixels used to capture an image.EV (Exposure Value)All the combinations of the camcorder’s shutter speed and lens aperture that result in thesame exposure.ExposureThe amount of light allowed to reach the camcorder’s sensor. Exposure is controlled by acombination of the shutter speed, the aperture value, and ISO sensitivity.Focal lengthThe distance from the middle of the lens to its focal point (in millimeters). Longer focallengths result in narrower angles of view and the subject is magnified. Shorter focallengths result in wider angles of view.F. No (F-Number)The f-number defines the brightness of lens. Smaller number lens has generally brighterimage. The f-number is directly proportional to the focal length and inversely proportionalto the lens diameter.*F.No=focal length/diameter of lens apertureMPEG-4 AVC/H.264MPEG-4 AVC/H.264 defines the latest video coding format standardized by the ISO-IECand the ITU-T, in 2003. Compared with the conventional MPEG-2 format, MPEG-4 AVC/H.264 has more than twice the efficiency. Your camcorder employs MPEG-4 AVC/H.264to encode high definition videos.Optical zoomThis is a general zoom which can enlarge images with a lens and does not deterioratequality of images.QualityAn expression of the rate of compression used in a digital image. Higher quality imageshave a lower rate of compression, which usually results in a larger file size.ResolutionThe number of pixels present in a digital image. High resolution images contain morepixels and typically show more detail than low resolution images.Shutter speedShutter speed refers to the amount of time it takes to open and close the shutter, and itis an important factor in the brightness of a photo, as it controls the amount of light whichpass through the aperture before it reaches the image sensor. A fast shutter speed allowsless time to let light in and the photo becomes darker and more easily freezes subjects inmotion.Tele MacroThis feature allows you to capture close-up images of very small objects. When using theTele Macro feature, the camcorder can maintain a sharp focus on small objects at a nearlife-size ratio (1:1).White balance (color balance)An adjustment of the intensities of colors (typically the primary colors red, green, andblue), in an image. The goal of adjusting the white balance, or color balance, is to correctlyrender the colors in an image.Glossary
