IMAGE FLIP CONTROL
Another built in function is the electronic image flip. This function is very useful when the
camera is mounted on a vehicle (carrier) that is capable of rolling over or a positioner that
can tilt more than 90°. This function allows the user to electronically turn the image upside
down when necessary.
To activate or deactivate this function EXPOSURE INC (+12Vdc) and FOCUS NEAR
(+12Vdc) must be toggled simultaneously. As a way of visual acknowledgement whenever
this function is activated or deactivated the camera will momentarily will text overlay the
current function status (e.g. IMGFLP ON or IMGFLP OFF) depending of the state of the
function and if the overlay has is activated.

NEGATIVE COLOR VIDEO CONTROL
Another built in function is the negative color video effect. This function is useful when an
immediate change in contrast is needed. For example dark colors will be turned in white
and simultaneously a light colors as well white illumination will turn dark. Allowing the user
to see details in a shadowed area, like a crack.
To activate or deactivate this function EXP DEC (-12Vdc) and FOCUS FAR (-12Vdc) must
be toggled simultaneously. As a way of visual acknowledgement whenever this function is
activated or deactivated the camera will momentarily will text overlay the current function
status (e.g. NEGVID ON or NEGVID OFF) depending of the state of the function and if the
overlay has is activated.

COMPUTER CONTROL
ROS can furnish basic software for enabling computer control through an RS-232
communications link. The basic software displays a screen on the computer monitor with
sliders, buttons and other symbols that allow the use of a mouse to provide even more
functions than those listed above.
The serial code for camera commands can also be furnished by ROS for users who prefer
to develop their own customized software.
Cameras can be furnished with connections allowing not only control but feedback of data
from the camera to the computer to display date, time, focus distance and other data
generated within the camera electronics module. Again, some users may prefer to develop
their own software allowing customized and added sophistication.
