Glossary of terms
AE (Automatic Exposure)
The camera’s built-in exposure meter automatically sets the exposure.
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).
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.
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.
Effective Pixel Resolution
The number of pixels used in the CCD to create the image.
EV (Exposure Value)
A system for measuring exposure. EV 0 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).
Gross Pixel Resolution
The total number of pixels in a CCD. Not all pixels are used to create the
image.
