Basic Functions
Back Light 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.
Wide Dynamic Range Mode (WD)
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).
Wide Dynamic Range Auto On/Off Mode
The wide dynamic range can be set to be automatically
switched ON/OFF in accordance with the intensity
difference obtained by dividing an image into several
blocks and then averaging the intensity of each block.
Wide Dynamic Range Auto On/Off Mode
When the intensity
difference between the
dark portions and light
portions of a subject
becomes large because
of back lighting or the
like, the wide dynamic
range mode is switched
ON.
Auto On/Off
When the subject
changes and the
intensity difference
between the dark
portions and light
portions becomes small,
the wide dynamic range
mode is switched OFF.
The wide dynamic range mode includes the following
operation modes.
WD Mode
This mode corrects blocked-up shadows and blown-
out highlights in accordance with the intensity
difference.
WD Auto ON/OFF Mode
This mode switches WD ON/OFF automatically in
accordance with the intensity difference of the
subject.
Configure the sensitivity for when WD is switched
from OFF to ON with the detection sensitivity
parameter.
Exposure Ratio Mode
This mode fixes the shutter speed of a long exposure.
Configure the shutter speed of a short exposure by
setting the ratio with regards to a long exposure with
the exposure ratio parameter.
Blown-out highlight correction is not performed in
this mode.
Histogram Mode
This mode uses a histogram to correct blocked-up
shadows and blown-out highlights.
About WD Set Parameter
(Command: 8x 01 04 2D 0p 0q 0r 0s 0t 0u 00 00 FF)
p: Screen display (0: Combined image, 2: Long-time,
3: Short-time)
Set the screen display to the combined image, a
long exposure image or short exposure image.
q: Detection sensitivity (0: Low, 1: Mid, 2: Hi)
Select from three levels for detecting the
intensity within the image for when switching
Auto WD from OFF to ON.
r: Blocked-up shadow correction level can be
set to one of four levels. (0:L 1:M 2:H 3:S)
s: Blown-out highlight correction level can be
set to one of three levels. (0:L 1:M 2:H)
tu: Parameter to use in the exposure ratio mode.
Specify the short exposure time by setting
the magnification ratio (×1 to ×64) with
regards to a long exposure time.
Notes
• When the wide dynamic range mode is ON, solarization may be
observed in the images of some subjects. This phenomenon is
unique to wide dynamic range mode, and is not an indication of a
camera malfunction.
• The frame rate during Wide Dynamic Range mode will be half of
that during standard mode.
Example: When Wide Dynamic Range mode is ON in 1080/30P
mode, the frame rate is 15 fps.
Noise Reduction
The NR (Noise Reduction) function removes noise
(both random and non-random) to provide clearer
images.
This function has six steps: levels 1 to 5, plus off.
The NR effect is applied in levels based on the gain,
and this setting value determines the limit of the effect.
In bright conditions, changing the NR level will not
have an effect.
