Glossary of terms
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 when the Record mode is set to SHQ, HQ, SQ. 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.
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.
Number of Pixels (PIXEL COUNT)
The number of dots (pixels) used to create an image denotes the image size. For instance, an
image in 640 x 480 resolution is the same size as the computer screen if the monitor setting is
also 640 x 480. If the monitor setting is 1024 x 768, the image only takes up part of the screen.
P (Program) Mode
Also called Program AE mode. The camera automatically sets the best shutter speed and
aperture for the shot.
Pixels
A pixel is the smallest unit (dot) used to make up an image. Clear large-sized printed images
require millions of pixels.
RAW
Refers to raw data, data which has not been enhanced with a camera option like white balance,
sharpness, contrast, etc. This file format is for viewing and processing with our own software. You
may not be able to open or process these files with other graphics software applications, and
these files cannot be selected for DPOF printing. RAW files are assigned an orf file extension
(*.orf).
S (Shutter Priority) Mode
Also called Shutter Priority AE mode. The user selects the shutter speed and the camera
automatically varies the aperture so that the picture is taken with the best exposure.
Single-lens reflex camera
A camera with a shooting lens working also as the viewfinder lens. The image of the subject
enters through the lens, reflects off of the mirror and into the pentaprism, where focus is
adjusted, then through the viewfinder lens. Pictures are taken by framing the composition and
adjusting the focus in the viewfinder lens.
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 get out of the sleep mode, use any button on the camera
(shutter button, arrow pad, etc.)
