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 origi-
nal level of performance cannot be achieved.
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.
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. Like-
wise, when the light is halved, the EV decreases by 1.
The frame rate is a unit used to indicate the number of images (frames) played back
per second. This camera shoots movie files at 10 consecutive frames per second, a
rate that is expressed as 10 fps. By comparison, TV images are played at 30 fps.
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.
If an Ni-MH battery is repeatedly charged without first being fully discharged, its
performance may drop below its original level. This is referred to as the "memory
effect".
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.
A generic term for cards that meet the PC Card Standard.
A standard for PC cards determined by the PCMCIA.
Personal Computer Memory Card International Association (US).
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.
Exif Print Format is a newly revised digital camera file format that contains a variety
of shooting information for optimal printing.
