Explanation of Terms
Deactivated batteries:
Leaving an Ni-MH battery unused in storage for a long period may cause a rise in the level
of substances that inhibit current flow inside the battery and result in a dormant battery. A
battery in this state is referred to as deactivated.
Because current flow is inhibited in a deactivated Ni-MH battery, the battery’s original level
of performance cannot be achieved.
EV:
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 main-
tains 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-sec-
ond 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.
Memory effect:
If an Ni-MH battery is repeatedly charged without first being fully discharged, its perfor-
mance may drop below its original level.
This is referred to as the “memory effect”.
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:
Exif Print Format is a newly revised digital camera file format that contains a variety of
shooting information for optimal printing.
