G
Shading Corrector
This corrects shading introduced by both the optics and the
imaging tube to help utilize the contrast enhancement feature
most effectively.
G
Diagonal Shading Corrector
This corrects the direction of a diagonal.
G
Video Booster
The video booster modifies the contrast in dark portions of the
image revealing details which were lost due to their low
intensity.
FUNCTIONS
G
Automatic Gain Control: AGC
Excellent overall image contrast can be achieved automatically
using this feature. This eliminates the need for manual
adjustments in situations where light intensity fluctuates over
time.
G
Operational Video Output (Optional)
External processing of video signals is simplified by the
operational video output. Operational video does not include
synchronization signals so it can be used to display DC signals
with black level as 0 volts.
G
All Timing is Crystal Clock Controlled.
By using a crystal oscillator, synchronization is more stable
and higher quality images can be produced . All control
signals, including the deflection frequencies, are derived from
a crystal oscillator.
G
High Geometric Stability
It features high geometric (position and dimensional) stability.
Also, highly uniform and accurate images are obtained.
G
Level Indicator
Two LEDs, which monitor input light intensity, provide a unique
and rapid method for the accurate determination of the
illumination level required to produce optimal image quality.
In addition, this feature provides a visual indication of
potentially damaging extreme light levels.
G
Video Tube Protection Circuit
A protection circuit has been incorporated to prevent damage
to the imaging tube, should the horizontal or vertical
synchronization signals be lost.
G
Video Inverter
The video inverter produces a negative image by inverting the
video intensity values. When used in conjunction with contrast
enhancement, this feature is particularly valuable for improving
detectability and image quality in low intensity regions.
In addition, it is very effective in facilitating the visual
interpretation of high contrast images.
G
White Clipper
The white clipper operates to suppress the level of the video
signal when it exceeds a preset level, in order to maintain
consistently high image quality on the TV monitor.

G
Contrast Enhancement
The contrast enhancement function amplifies video signals
that are above offset (threshold) level. Using this function, the
low contrast image is enhanced and changed into a clear
image.

After contrast enhancement
G
External Synchronization Control (Optional)
When utilizing external equipment, it may be necessary to
synchronize the scanning of the camera via this optional
control. This circuit automatically switches from the internal to
external synchronization when external horizontal and vertical
signals are provided.
