Appendix
ISO
A method for indicating film speed by the International Organization for
Standardization (ISO) (ex. “ISO100”). Higher ISO values indicate greater sensitivity
to light, so images can be exposed even in low-light conditions.
JPEG (Joint Photographic Experts Group)
A compression format for still images. Photographs (pictures) taken using this
camera are recorded onto the card in JPEG format. By downloading these images
to a computer, users can edit them using graphics application software or view the
images using an Internet web browser.
Noise reduction
When shooting in dark places, shutter speeds become slower as there is less light
focused on the CCD. During long exposures, signals are generated by parts of the
CCD where no light is focused and are recorded on the picture as noise. When noise
reduction works, the camera automatically reduces the noise to produce clearer
images.
NTSC (National Television Systems Committee)/PAL (Phase
Alternating Line)
Television formats. NTSC is mainly used in Japan, North America and Korea. PAL
is mainly used in Europe and China.
PictBridge
A standard for connecting digital cameras and printers of different makers and
printing out pictures directly.
Pixels
A pixel is the smallest unit (dot) used to make up an image. Clear large-sized printed
images require millions of pixels.
Program auto
Also called Program AE mode. The camera automatically sets the best shutter
speed and aperture for the shot.
Sleep Mode
A mode designed to save battery life. The camera automatically enters the sleep
mode if you do not operate it for a certain time. To exit the sleep mode, use any
button on the camera (shutter button, arrow pad, etc.).
TFT (Thin-Film Transistor) Color Monitor
A transistor color monitor constructed using thin-film technology.
