Noise Reduction; Custom Gamma Mode; Color Enhancement; Temperature Reading Function - Sony fcb-ev7500 Technical Manual

Set the area which you want to adjust the
brightness of the image with WD mode effect.
Default value: 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.
Default value: 1
Notes
• When the wide dynamic range mode is ON, false colors may
appear in some parts of the image. This phenomenon is unique to
wide dynamic range mode, and is not an indication of a camera
malfunction.
• When switching WD mode, images are shown at a maximum of 8
frames at the same time.
Visibility Enhancer (VE)
Using the Visibility Enhancer function will make the
darker part of a camera image brighter as well as
automatically correct brightness and contrast to show
bright parts clearly without overexposure.
Defog mode
When the surrounding area of the subject is foggy and
low contrast, the defog mode will make the subject
appear clearer.

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.
High Sensitivity Mode
In this mode, higher sensitivity gain is applied as
standard gain increases, reaching a gain level at MAX
gain of up to 4x the standard gain. In such cases,
however, there will be a high volume noise in the
image.

Custom Gamma Mode

Gamma correction can be changed in this mode. The
following two options are available.
0: Standard
1: Straight gamma
Tip
You can set the brightness from -16 (0h) to +64 (40h)
for each mode in Offset.

Color Enhancement

A color image can be created two colors brighter and
darker than the threshold value.
(The threshold level can be set.)
Color specifications
• You can select from nine colors to specify for the
high-intensity and low-intensity colors.
Color options: Yellow, cyan, green, white, magenta,
red, blue, black, gray
• The default settings for color specification are "green"
for high-intensity and "white" for low-intensity.
Threshold values
• You can set the threshold value that determines high
or low intensity.
• The minimum threshold value is 1h (decimal: 1), and
the maximum threshold value is FE1h (decimal:
4065).
• The default setting for the threshold value is 200h
(decimal: 512).

Note
Flicker on images with color enhancement is not a malfunction of
the camera. Flicker can be reduced by setting the aperture control.

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.
StableZoom™
StableZoom is a function for performing correction
using the Image Stabilizer function in accordance with
the zoom ratio, and smoothly zooming up to
approximately ×36 using a combination of the optical
