Glossary
CCD (Charge-Coupled Device)
This converts light passing through the lens into electrical signals. With this
camera, light is picked up and converted into RGB signals to build a single image.
DCF (Design rule for Camera File system)
A standard for image files by the Japan Electronics and Information Technology
Industries Association (JEITA).
Digital ESP (Electro-Selective Pattern) Light Metering
This determines the exposure by metering and calculating the light levels in the
center and other areas of the image separately. With this camera, this system
works when the metering mode is set to ESP.
DPOF (Digital Print Order Format)
This is for saving desired print settings on digital cameras. By entering which
images to print and the number of copies of each, the user can easily have the
desired images printed by a printer or print lab that supports the DPOF format.
EV (Exposure Value)
A system for measuring exposure. EV0 is when the aperture is at F1 and the
shutter speed is 1 second. The EV then increases by 1 each time the aperture
increases by one F stop or the shutter speed increases by one increment. EV can
also be used to indicate brightness and ISO settings.
Exposure
The amount of light used to capture an image. The exposure is determined by the
time the shutter is open (shutter speed) and the amount of light that passes
through the lens (aperture).
JPEG (Joint Photographic Experts Group)
A compression format for color still images. Photographs (images) shot using this
camera are recorded onto the card in JPEG format. By downloading these images to
a personal computer, users can edit them using graphics application software or
view the images using an Internet web browser.
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.
