Thus, color fading and changing can be observed over an extended
period of time.
The
Reset
button erases the existing coordinate graph and creates a
new graph.
The HSI model displays the color values in a color circle. The length
of the vector indicates the saturation level, and the direction of the
vector indicates the hue. Brightness is displayed in a gauge at the
bottom of the window.
Each value is also numbered.

Displaying Color Bars:
Select the
Color Bars option in order to test the Grabber.
The color bars are generated from hardware and not the demo
program. The number of bars displayed depends on size of the chosen
image. All color bars are displayed with a horizontal resolution of
aprox. 515 pixels.
•
Arithmetic Operations on Static Images:
The Arithmetics menu option provides some simple arithmetic
operations on static images (see Figure 32).
For example, images can be added, subtracted, multiplied or divided
pixel by pixel. In addition, a constant can be added to each pixel
(brightness changes) or the constant can be multiplied with each pixel
(contrast change).
