1. Introduction
This is an image processing unit that improves the visibility of objects by clarifying video images at
low contrast. Images whose visibility has lowered due to various factors such as low illuminance,
backlight, and fogs are optimized easy on human eyes. Our original real time image clarifying
technology "ForteVision" is introduced into the image clarifying processing. The built-in contrast
improvement processing and Gaussian noise lter processing have improved contrast and reduced
noise at low illuminance. The adopted video signal covers the analog composite signal and can be
easily built into the existing video transmission system.
Since image clarifying processing is executed automatically, it is not necessary to change the setting
of each parameter even when external light condition has changed.
Normally, no adjustment is necessary for the improvement level, but the image clarifying processing
strength level can be switched over in 3 steps while the noise lter strength level is switched over in 2
steps. (However, note that noise and contour may become obvious if the image clarifying processing
strength level is raised). This unit can be operated with the buttons on the front panel as well as by
the attached serial control software. (Since the items operative with the buttons on the front panel
are the same as those operative by the software, the software need not be installed unless the unit is
operated from a distance.)

When the video data from a video recorder is image-clarifying-processed and displayed on a
monitor:
When the image data from a camera is image-optimized and then outputted to a video
recorder:
* The image data from a camera can be optimized in real time.
When performing Quad (Quad partition image) processing:
* When the images from four cameras are synthesized into one image with an
external device such as a switcher, the image clarifying effect may be poor when
the difference in illuminance of the images from four cameras is excessively great.
In such a case, validate the Quad (Quad partition image) processing function.

5.1. Image clarifying processing adjust
The strength of image clarifying processing can be set in 3 steps by pushing /buttons.
Image clarifying processing improves images hard to see to those easy to see by correcting
the image contrast.The images under non-ideal external light conditions at low illuminance,
backlight or fogs are corrected suitably.

* We normally recommend "Normal" for setting since noise becomes obvious depending on
the image when strength is raised.
5.2. Operation on MENU screen
The setting of each function can be changed by pressing MENU button to open MENU
screen. The effect of the setting change is immediately reflected on the monitor display
image, and the changed setting is retained even after MENU screen is closed and the power
supply is turned OFF. The effect o f each function turns ON (Effective) when the image clarifying
processing strength is set ON.
* Only BLACK/Black level adjustment is ON (Effective) even when the image clarifying
processing strength is OFF.

5.2.1. FILTER / Noise lter strength adjustment
This function reduces noise without damaging detailed portions of image as much as possible.
Especially, the effect of this function is obvious in such a case when Gaussian noise is
increased in low illuminance portion.
Strength of the correction is set to 2 steps (Soft/Hard).

5.2.2. BLACK / Black level adjustment
When black level doesn't drop down to the correct level in the range of input video signal
swinging, the effect of image clarifying will be poor. In such a case, better image can
be obtained by adjusting the black level. The black level is adjusted while watching a
histogram that simply shows the luminance level.
Select "BLACK" in the adjustment menu, and adjust the leftmost bar in the histogram to a
position near Level 0 with/buttons.
* Accurate matching to Level 0 is needless as the histogram is only a guidance.
5.2.3. BRIGHT / Brightness adjustment
This function adjusts the brightness of output image. The standard setting is "50".
Low brightness portion becomes easy to see by adjusting this setting in the plus direction
when low brightness portion in the image is hard to see. On the other hand, the noise
outstanding at low brightness portions can be reduced by adjusting this brightness level in
the minus direction.
5.2.4. STATUS / Status display switchover
This function switches over the status display of output video image.
When set to "ON", the current status of image clarifying processing strength is displayed at
the upper right on the screen.
* Image clarifying processing strength is selected by the setting described in "5.1. Image
clarifying processing".
5.2.5. QUAD / Quad (Quad partition image) processing switchover
This function divides input image into quad (Quad. partition) images and provides each
partition image with an appropriate image clarifying processing.
When the images from four cameras are synthesized into one image with an external
device such as a switcher, the image clarifying effect may be poor when the difference in
illuminance of the images from four cameras is great. In such a case, validate the Quad
(Quad partition image) processing function. (Refer to "4.3. Connection diagram".)
5.2.6. EXIT / MENU screen deletion
This function erases MENU screen.
* MENU screen will be also erased when this unit is left for approx. 20 seconds without any
operation or MENU button is held pressed for approx. 3 seconds.
