Exposure Compensation
Exposure compensation is a function which offsets the
internal reference brightness level used in the AE
mode, by steps of 1.5 dB.
Data Step Setting value
0E +7 +10.5 dB
0D +6 +9 dB
0C +5 +7.5 dB
0B +4 +6 dB
0A +3 +4.5 dB
09 +2 +3 dB
08 +1 +1.5 dB
07 0 0 dB
06 −1 −1.5 dB
05 −2 −3 dB
04 −3 −4.5 dB
03 −4 −6 dB
02 −5 −7.5 dB
01 −6 −9 dB
00 −7 −10.5 dB
Slow AE (Auto Exposure)
The slow AE Response function allows you to reduce
the exposure response speed. Usually the camera is set
up so that the optimum exposure can be obtained
automatically within about 1 second. However, using
the slow AE response function allows you to lengthen
the auto exposure response speed from the initial setup
speed (01h) to approx. 10 minutes (30h) (at normal
shutter speed).
For example, with the normal setting (about 1 second),
if the headlights of a car are caught by the camera, the
camera automatically adjusts the exposure so that it can
shoot a high-intensity subject (in this case, the
headlights). As a result, images around the headlights,
that is, the rest of the subject, except the headlights,
becomes relatively dark, and poorly distinguished.
However, using the slow AE function means the AE
response speed will be slower, and response time will
be longer. As a result, even if the camera catches a high-
intensity subject (e.g., the headlights) for a moment,
you can still easily distinguish the portions of the image
surrounding the headlights.
Aperture Control
Aperture control is a function which adjusts the edge
enhancement of objects in the picture. There are 16
levels of adjustment, starting from “no enhancement.”
When shooting text, this control may help by making
them sharper.
Backlight Compensation
When the background of the subject is too bright, or
when the subject is too dark due to shooting in the AE
mode, back light compensation will make the subject
appear clearer.
Note
Wide-D/HLC/Backlight Compensation/Spot Exposure Mode do
not work at the same time.
Wide Dynamic Range Mode (Wide-D)
The Wide Dynamic Range mode is a function for
dividing an image into several blocks and correcting
blocked-up shadows and blown-out highlights in
accordance with the intensity difference. It enables you
to obtain images in which portions ranging from dark
to light can be recognized, even when capturing a
subject with a large intensity difference that is backlit
or includes extremely light portions.
Images with wide dynamic range are produced by
combining long-exposure signals (normal shutter) with
the signals of the high-intensity portions obtained with
a short exposure (high-speed shutter).
• About Wide-D Set Parameter
(Command: 8x 01 04 2D 00 0q 0r 0s 00 00 00 00 FF)
q: Display brightness
(0: Dark to 6: Bright)
The brightness and the darkness can be
adjusted to seven levels. The normal brightness
is set to 3.
Initial setting: 3
r: Brightness compensation selection
(0: Darker, 1: Dark, 2: Standard, 3: Bright)
Set the area which you want to adjust the
brightness of the image with Wide-D effect.
Initial setting: 2
s: Compensation level
(0: Low, 1: Mid, 2: High)
The compensation of the brightness, which you
select from the parameter, can be set to three
levels.
Initial setting: 1
Notes
• When the Wide-D is On, false colors may appear in some parts of
the image. This phenomenon is unique to Wide-D, and is not an
indication of a camera malfunction.
• When Wide-D is switched, images may be disported.
• Wide-D/HLC/Backlight Compensation/Spot AE do not work at
the same time.
• After the Wide-D ON/OFF switchover, the Visca command will
not be accepted for up to 2 seconds and an error message may be
returned from the camera.
