14910 AppendixGlossary of termsCCD (Charge-Coupled Device)This converts light passing through the lens into electrical signals. On this camera,light is picked up and converted into RGB signals to build a single image.Conventional PhotographThis refers to recording images using silver halide (the method for recording imagesin conventional, non-digital photography). This system is in contrast to still video anddigital photography.DCF (Design Rule for Camera File System)A standard for image files by the Japan Electronics and Information TechnologyIndustries Association (JEITA).DPOF (Digital Print Order Format)This is for saving desired print settings on digital cameras. By entering which imagesto print and the number of copies of each, the user can easily have the desiredimages printed by a printer or print lab that supports the DPOF format.ESP (Electro-Selective Pattern) Light Metering/Digital ESP LightMeteringThis determines the exposure by metering and calculating the light levels in thecenter and other areas of the image separately.ExposureThe amount of light used to capture an image. The exposure is determined by thetime the shutter is open (shutter speed) and the amount of light that passes throughthe lens (aperture).Image sizeThe size of an image expressed by the number of pixels that make up the image. Forinstance, a picture taken with an image size of 640 × 480 fills the computer screenwhen the monitor setting is 640 × 480. However, if the monitor setting is1,024 × 768, the picture only takes up part of the screen.ISOA method for indicating film speed by the International Organization forStandardization (ISO) (ex. “ISO100”). Higher ISO values indicate greater sensitivityto light, so images can be exposed even in low-light conditions.JPEG (Joint Photographic Experts Group)A compression format for still images. Photographs (images) shot using this cameraare recorded onto the card in JPEG format. By downloading these images to apersonal computer, users can edit them using graphics application software or viewthe images using an Internet web browser.NTSC (National Television Systems Committee) / PAL (PhaseAlternating Line)Television formats. NTSC is mainly used in Japan, North America and Korea. PALis mainly used in Europe and China.
