Appendix
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.
Noise reduction
When shooting in dark places, shutter speed 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.
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.
