service to you.
1-2. Features
Easy addition to an existing system by directly connecting a CCD security camera
Video stabilization in real time and for recorded VCR videos
Shake correction in two demensions, including vertical, horizontal, diagonal and rotational
Sub-pixel level correction precision
Optimal correction of bright and dark spots in video signals to allow clear images to be output
Date/Time display and Title display of up to 16 characters x 1 line
Remote control via web browser
1-3. Notes on Using IVS-200
Use the highest possible shutter speed for the shooting camera. Shooting moving objects
with a low shutter speed will result in a blurred and low-resolution image. A shutter speed of
1/240 sec. or higher is recommended, although the result will depend on the shooting
subjects, shaking speed and other conditions.
IVS-200 may not properly detect shaking images with some video images as described
below;
1) Images with uniform luminance
Example: A wall or floor where the luminance level is almost the same throughout the
image
2) Images with luminance changing in a single direction
Example: Test signals such as Ramp and Color bar for which the luminance level
changes only horizontally, not vertically.
3) Images with alternating changes in luminance
Example: Images with an object such as a blind where luminance level changes cyclically.
4) Images with movements in multiple directions
Example: Images with a large object crossing in front of other objects
Scene cut or sudden change of input images may result as if there is panning or tilting.
Usually the correction returns to a normal state after a while, though it may not return to
normal depending on the Motion Filter setting.
If a sudden change of images is expected in the input video, turn the STABILIZE menu off
before the scene. Turn it back on after the input video returns to normal. (See section “” for
details on the STABILIZE setting.)
Please do not put other devices on or under this unit in order to ensure proper operation. In
such case, note that the unit temperature must be kept 10°C lower than specified in the
specifications given at the end of this manual.

5-3-1. Shake Correction ON/OFF (STABILIZE)
When STABILIZE is set to ON, shake correction is activated. When STABILIZE is set to OFF,
shake correction is inactivated, however, images are magnified according to the set
correction level. If the OPERATE/BY-PASS toggle switch on the front panel is set to BY-PASS,
input signals are bypassed and output from the VIDEO OUT 1 connector without correction.
See section 2-2. “Rear Panel”(2) VIDEO OUT 1/2 for details.
5-3-2. Correction Level (CORRECTION LEVEL)
The Correction Level menu allows you to select a correction level according to the shake
amplitude. The magnification percentage is also displayed for the selected level. The
IVS-200 crops images to output stable video when shaking is detected. The cropped images
become smaller than the original size, so that they will be magnified. The high correction
level allows you to correct for large amplitude shaking. However, the resulted image shows a
small part of the original input image. (i.e., Magnified by a high percentage.) The low
correction level cannot allow you to correct for large shaking. However, the larger part of the
original input image can be displayed. (i.e., Magnified by a low percentage.) See appendix
“Input Image and Correction Range” for the details on the relation between correction and
magnification.
<For your reference>
Lower than 4: effective for small vibrations caused by machines, wind, etc.
5 to 10: effective for camera shake, wheel deflections, etc.
Higher than 10: effective for high zooming, for objects very close to the camera, or for
images with significant rotational shaking.
Displayed area Large Small
Correction range Small Default Large
0 (100%) 10 (125%) 15 (143%)
Correction level 0 (100%) can also correct for slight shaking.
5-3-3. Filter Level (MOTION FILTER)
The Motion Filter menu allows you to select a filtering level (shake correction strength) to
achieve smooth shake correction. The level can be selected separately for horizontal, vertical
and rotational correction in the range between 0 and 16.
Set the filter level high to give priority to video stabilization.
Set the filter level low to give priority to smoothness of images.
Filter levels between 14 and 16 are effective for fixed cameras for fixed-point observations.
Filter levels between 1 and 6 are effective for mobile cameras.
Filter level 0 disables shake correction.
To disable shake correction only for rotational shaking while enabling the correction for
horizontal and vertical shaking, set MOTION FILTER (R) to 0.
