Explanation of Terms

DPOF:

Digital Print Order Format

DPOF is a format used for recording information on a storage media (image memory card, etc.) that allows you to specify which of the frames shot using a digital camera are printed and how many prints are made of each image.

EV:

A number that denotes Exposure Value. The EV is determined by the brightness of the subject and sensitivity (speed) of the film or CCD. The number is larger for bright subjects and smaller for dark subjects. As the brightness of the subject changes, a digital camera maintains the amount of light hitting the CCD at a constant level by adjusting the aperture and shutter speed.

When the amount of light striking the CCD doubles, the EV increases by 1. Likewise, when the light is halved, the EV decreases by 1.

JPEG:

Joint Photographics Experts Group

A file format used for compressing and saving color images. The compression ratio can be selected, but the higher the compression ratio, the poorer the quality of the expanded image.

Motion JPEG:

A type of AVI (Audio Video Interleave) file format that handles images and sound as a single file. Images in the file are recorded in JPEG format. Motion JPEG can be played back by QuickTime 3.0 or later.

MP3:

An acronym for MPEG1 Audio Layer 3. Denotes an audio compression format included in the MPEG video and audio compression standard. The MP3 format compresses audio data to approximately 1/10 of its original size by excluding all audio information that is not audible to humans.

PC Card:

A generic term for cards that meet the PC Card Standard.

PC Card Standard:

A standard for PC cards determined by the

PCMCIA.

PCMCIA:

Personal Computer Memory Card International Association (US).

PNG:

An acronym for Portable Network Graphic.

As the name suggests, this is an image format created to facilitate the handling of image data over networks and has emerged as the new replacement for the GIF format. As such, it has many of the GIF format characteristics (optimized for graphics, compact file sizes and lossless compression) but does not have the limitations of the GIF format, such as being restricted to 256 colors.

VGA:

A graphics standard for personal computers that indicates an image size of 640⋅480 pixels.

WAVE:

A standard format used on Windows systems for saving audio data. WAVE files have the “.WAV” file extension and the data can be saved in either compressed or uncompressed format. This camera use PCM recording.

WAVE files can be played back on a personal computer using the following software:

Windows : MediaPlayer

Macintosh: QuickTime Player

✽QuickTime 3.0 or later

White Balance:

Whatever the kind of the light, the human eye adapts to it so that a white object still looks white. On the other hand, devices such as digital cameras see a white subject as white by first adjusting the color balance to suit the color of the ambient light around the subject. This adjustment is called matching the white balance. A function that automatically matches the white balance is called an Automatic White Balance function.
