Description
The Color Balance Tool allows you to correct the color on an
image
by defining what black and white should be in the image.
Often
the lighting and contrast are not perfect. Consequently, something that
the camera
should see as white appears as grey. With this tool you
can tell the program that the grey grey it is picking up should
actually be white. By difining black and white in a given
setup
you can have a better initial image in your applications.


Training
Black and White
There are several ways that you can use the Color Balance
tool
to enhance your image.
- To begin with you must drag the tool onto your
program.
- Next you should grab an
image from the camera. You
will use this image to train black and/or white.
- Right
click the Color Balance Tool in your program and
choose "edit". This will display the Color Balance Tool
property
page.

Train
Black/White Auto
The easiest way to use
this tool is to click the "Train Black Auto" and "Train White Auto"
buttons. These buttons tell the program to survay the current
image and define what black and white should be.
Train Black/White Manual
If you would like to
numerically set what black and white should be you will use these
buttons. After replacing the numeric values listed for black
and
white (the values listed to the left of the "Train Reset" button)
clicking the respective "Train Manual" button will let the program know
that the values you entered you want to use for the application.
Train
Black/White
You can also train black
and/or white based on the colors available in the current
image.
Once you have grabbed you image from the live feed, before you enter
the property page, you can tell the program where to look to find
either white or black. Clicking the Color Balance Tool in
your
program will display a small box on the current image. If you
want to train white, resize this box over the part of the image you
think should be defined as white. When you have done this
right
click the the Color Balance tool in your program and choose
"edit".
Clicking the "Train White" tool will define whatever is in the box as
white.
Using the Color Balance Tool
Once you have trained black and white to your
liking you will
need
to apply these changes to your image. Click the Color Balance
Tool to display the selection box. This tool will only apply
the
new color balance within the selection box. If you would like
the
entire image to be affected you will need to enlarge the selection box
over the whole image.
Once you have selected the necessary portion of the image, right click
the Color Balance Tool and choose run. This will apply the
Color
Balance effect you have prepared.
