Sony FCB-CX12E Technical Manual page 12

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 short exposure.
Configure the shutter speed of a long exposure by
setting the ratio with regards to a short exposure with
the exposure ratio parameter.
Blocked-up shadow 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

p: Screen display (0: Combined image, 1: Long/short
division, 2: Long-time, 3: Short-time)
Set the screen display to a WD combination
image, long/short exposure division image,
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 ×150) with
regards to a long exposure time.

Note
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.
Noise Reduction
The NR (Noise Reduction) function removes noise
(both random and non-random) to provide clearer
images. By combining 2D filtering according to
brightness and image color, and 3D filtering according
to noise caused by motion and time difference, lower-
noise images can be obtained for the corresponding
image brightness of a moving subject.
This function has six steps: levels 1 to 5, plus off.
Level 1 applies to subject motion mainly using 2D filter
effects. With level 5, 2D and 3D filter effects are
maximized, providing the lowest-noise images,
although moving subjects may show trails.
At each level, two filters are set according to noise and
image motion characteristics, so the available level
selections depend on the situation. The default setting
is level 3.
Color Enhancement
A captured color image is converted to 256 levels of
gray, and the binarization process is performed to
convert all gray levels brighter than the threshold value
to white, and all gray levels darker than the threshold
value to black. (Any value can be set for the threshold
level and hysteresis width.) Furthermore, any color can
be assigned to each of the negative and positive.
Note
Flickering in images during color enhancement is not an indication
of a camera malfunction. It can be reduced with the threshold level,
hysteresis width, and edge enhancement (aperture) settings.

Temperature Reading Function
The conversion value (hex) of the temperature sensor
built into to the camera can be read by using a query
command. The conversion value has an error of ±3 C,
and because the temperature sensor is inside the
camera, this value is not the ambient temperature. Use
it as a reference value.
