Appendix
Image size
The size of an image expressed by the number of pixels that make up the image. For
instance, a picture taken with an image size of 640 × 480 fills the computer screen
when the monitor setting is 640 × 480. However, if the monitor setting is
1,024 × 768, the picture only takes up part of the screen.
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 (images) shot using this camera
are recorded 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.
M (Manual) Mode
The user sets both the aperture and shutter speed.
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.
P (Program) Mode
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.
TTL (Through-The-Lens) System
To help adjust exposure, a light receptor built into the camera directly measures the
light passing through the lens.
