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 filter 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 filter 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.)
