Explanation of Terms
AF/AE Lock:
On the FinePix S20 Pro, pressing the Shutter button down half way locks the focus and exposure settings (AF and AE lock).
If you want to focus on a subject that is not centered in the frame or change the picture composition after the exposure is set,
you can obtain good results by changing the composition after the AF and AE settings are locked.
Auto power save function:
If the camera is not used in any way for 30 seconds, this function turns features such as the LCD monitor off (Sleep mode) to
prevent battery depletion and the waste of power when the AC power adapter is connected. If the camera is then left unused
for a further period, the Auto power save function turns the camera off. This period can be set to 2 minutes or 5 minutes on
this camera.
h
The Auto power off function does not operate in PC mode, during automatic playback, or if it is disabled during setup.
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.
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 to be 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.
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.
JPEG:
Joint Photographics 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 performance 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.
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).
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.
