Basic Glossary of Digital Camera Terms

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.
