Basic Glossary of Digital Camera Terms
AE (Auto Exposure)
Automatic exposure is the function by which the camera automatically adjusts the exposure (the shutter speed
and aperture settings) to suit the brightness of the subject.
AF (Auto Focus)
The function by which the camera automatically focuses images.
Aperture
This is a mechanism inside the camera lens that controls the amount of light passing through the lens by
changing the size of an opening.
Aperture setting
A number that indicates the size of the aperture opening. Settings are displayed as numbers such as F2.8, and
the higher the aperture setting, the smaller the opening and the less light that passes through the lens.
Aperture-priority AE
This is a type of automatic exposure where the photographer selects the aperture setting and the camera then
automatically sets the optimum shutter speed for the shot. By setting the aperture, the photographer can control
the depth of field in the shot.
CCD (Charge Coupled Device)
This is a device that converts the light that enters the camera through the lens into digital information. Strictly
speaking, a CCD is a tiny component and many hundreds of thousand of CCDs are used to make up the
imaging element in a digital camera. The number of CCDs is referred to as the number of pixels. The larger the
number of pixels, the greater the amount of information generated by converting light and the higher the
resolution of the image.
DCF (Design rule for Camera File system)
This is a standard that stipulates items such as the file formats for digital cameras and related devices. In
principle, digital cameras that conform to the DCF standard can freely exchange images, even when the
images were shot with a different brand of camera. This camera complies with the DCF standard.
