Explanation of Terms

A number 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.

Frame rate (fps)

The frame rate refers to the number of images (frames) that are photographed or played back per second. For example, when

10 frames are continuously photographed in a 1-second interval, the frame rate is expressed as 10 fps.

For reference, TV images are displayed at 30 fps (NTSC).

JPEG

Joint Photographic Experts Group

A file format used for compressing and saving color images. The higher the compression rate, the greater the loss of quality in

the decompressed (restored) 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.

Smear

A phenomenon specific to CCDs whereby white streaks appear on the image when there is a very strong light source, such as

the sun or reflected sunlight, in the photography screen.

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. Uncompressed recording is used on this camera.

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.

Exif Print Format is a newly revised digital camera file format that contains a variety of shooting information for optimal printing.
