Color
Check:
(IPToolColorCheck)
The Color Check tool allows you to measure how close a color is to a
trained (reference) color.
Using the Color Check Tool
When the Color Check tool is dragged onto a sequence/playlist a
small green box will appear on the viewer window. (When selected this
box will turn red.) This box can be moved and resized over any area in
the viewer window.

To train a color to use as your reference
point, drag the box over the color you wish to select. To
train
the selected color, right-click the Color Check tool icon in the
playlist and choose "Train".

Now
that
you have trained your color you can move your selection box to another
part of the screen to do a color check. [This is only to
allow
you to understand how the color check works. In a typical
program
you would be grabbing live images and running the test over and over in
roughly the same area.]
- Move
the selection box so that it is completely over the blue part of our
logo.
- Right-click
the Color Check tool icon in the program/playlist and choose "Run."
This will compare the currently selected color to the trained color.
- Once
you have run the tool in this way you can look at the
results.
Right-click the Color Check tool icon again and choose edit to view the
results.

The
results are given in the color tab of the Color Check tool property
page. The color that you trained to be your reference point
is
shown numerically in the Train column and the color you just selected
to compare is shown in the sample column. The
"Distance" box shows how different the two colors are. The
higher
the distance number the greater the color difference. A distance of
"0.0" is a perfect match. Note: Results will not be displayed
unless a Color Space is selected.
Color Space
The color can be analyzed according to a number of different color
spaces. In this case I have used the standard RGB color
space. Each color space has its own mathematical formula for
determining the numeric value of a given color. Automation
Manager has integrated several different color spaces that you can use
to meet whatever needs you have. The color spaces are:
RGB
HSI
CIE - 3 variants
CMY
LUV
LAB
XYZ
HSV
HSL
