Contrast Adjustment Function; Temperature Reading Function; Image Stabilizer; Low-Illumination Chroma Suppress Mode - Sony FCB-EV7520A Technical Manual

• The Flicker Reduction may not work if the subject is bright under
an environment where flicker occurs. If the shutter speed is 1/100
(flicker frequency 50 Hz) or 1/120 (flicker frequency 60Hz) and
the brightness exceeds the Iris variable area (F14), stop the Flicker
Reduction and run a normal AE operation.
Variable Gamma Mode
There are standard (00h) mode and straight gamma
(01h) mode.
Gamma Offset
You can set the brightness from –64 to +64 in each
mode of variable gamma mode.

Contrast Adjustment Function

You can adjust the contrast level in the range from
0 (00h) to 255 (FFh). The initial setting is 128 (80h).
The smaller the value is, the lower the contrast
becomes, and the larger the value is, the higher the
contrast becomes.
Note
This function is available when the variable gamma mode is set to
standard (00h) mode and when VE/Wide-D/HLC are set to OFF.

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.

Image Stabilizer

Switching On the Image Stabilizer function reduces
image blurring caused by, for example, vibration, which
allows you to obtain images without much blurring. A
correction effect is possible for a vibration frequency of
around 10 Hz. The Image Stabilizer function employs
the digital zoom system, so the angle of view and
resolution are changed, but the sensitivity is
maintained.
"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
zoom and digital zoom. As no digital zoom by the
Image Stabilizer is available on the wide side, you can
obtain a wider image with no resolution degradation.
Only the electronic zoom operates between Wide end
and 1.2×, and only the optical zoom operates between
1.2× and Tele end. The Image Stabilizer does not work
between Wide end and 1.2×, and only works after 1.2×.
The "StableZoom" function can be switched On/Off in
the register settings.

Hold Function of Image Stabilizer
With the Image Stabilizer function, suddenly stopping
high-speed movement (pan, tilt, etc.) of the camera
produces a blur sensor counteraction that may cause
image movement. In such a case, you can use a
command setting (hold) to maintain the correction of
the Image Stabilizer function. In this case the image
stabilizer is off, but there is no change in the angle of
view.
Note
The hand shake correction function may not work correctly under
the condition that high-frequency vibra tion component exits. In
such a case, set the image stabilizer function to Off.
Auto Slow Shutter On/Off
When set to "On, " the slow shutter functions
automatically when the light darkens. This setting is
available only when the AE mode is set to "Full Auto. "
The initial setting is "Auto Slow Shutter Off. "

Low-Illumination Chroma Suppress Mode

You can configure a chroma suppress mode for low-
illumination conditions. This can be useful when color
noise is particularly noticeable in such conditions.
Four levels (disabled and three levels) are available for
the low-illumination chroma suppress mode.
