AE (Auto Exposure)
This refers to automatic exposure, which is the mechanism by which the camera
automatically adjusts the exposure.
AF (Auto Focus)
The mechanism 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 used as the imaging element in a digital camera. Strictly speaking, a CCD is
used for transferring electrical signals and is governed by a semiconductor device called a
phototransistor that converts light into electrical signals. The integrated unit made up of the
phototransistor and the CCD that transfers the electrical signals is called a CCD imaging
element and is the heart of any digital camera.
DCF (Design rule for Camera File system)
This is a standard adopted by the Japan Electronics and Information Technology Industries
Association (JEITA) 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 on a different brand of camera. This
camera complies with the DCF standard.
Depth of field
When a subject is in focus, the depth of field refers to the area in front of and behind the
subject that is also in focus. The depth of field increases when the aperture setting is high.
Such shots are said to have a large depth of field. Conversely, lower aperture settings give
a narrow range in which objects are in focus. This is referred to as a small depth of field.
The depth of field becomes smaller when the subject is closer to the camera.
DPOF (Digital Print Order Format)
DPOF is a standard used for printing images photographed using a digital camera on a
home printer or at a commercial print processing store. When the number of prints of
photographed images that are required and the format of those prints are specified in the
DPOF settings on a DPOF-compatible camera, those prints can then be produced as
specified in the DPOF settings using a DPOF-compatible printer or by a commercial print
processing store that provides a DPOF print service. This camera is DPOF compatible.
The DPOF trademark indicates that the product conforms to the specifications of the “Digital
Print Order Format (DPOF) for digital camera print information”. Copyright for DPOF
