CCD (Charge-Coupled Device)
This converts light passing through the lens into electrical signals. On 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).
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.
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).
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.
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.
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.
