Tuning Guidelines: Color Balance
39 SMX-M7xx Series USB2.0 Camera User Guide
Click the Best button to automatically achieve the optimal combination of brightness,
contrast and gamma instead of setting them manually. As the result, the application will
transform the look-up table of 8 and 10 bit to increase the dynamic range.
Note The default values of Image Correction are the most suitable and recommended for performing White Balance
(Hard).
The SMX-M7x camera software does not display changes of the Image Correction look -up table when the Best
button is pressed.
With every change of any Image Correction control, you can view a graphical
interpretation of dependence of the image's changes from the changes of the Image
Correction controls.
Color Balance
The Color Balance Controls are designed for the SMX-M72 and SMX-M73 (color)
models to adjust the ratio of the main induced color components (Red, Green and
Blue) of the image. This correction is performed on the software level and does not
affect any electrical settings of the camera.
To use the Color Balance Controls, set the Enable check box on the Color Balance tab
- R, G and B sliders become editable.
Figure 4-11 Enabling the Color Balance Controls
Use the White Balance button for white color balancing (the same can be done in
Device> White Balance or by pressing w on the keyboard) on the Color Balance tab.
The Default button returns the color balance controls to their default values: 1.00; 1.00;
1.00, respectively.
Single step of the Color Balance controls is 10 times smaller than R, G, B (Gain) of the
Sensor Controls, so all changes of Color Balance can be performed with more
accuracy than it can be done using R, G, B (Gain) of Sensor Controls.
Note: The difference between White balance (Soft) and White Balance (Hard) is as follows: the White Balance (Soft)
operation is done only on the software level, so it changes the Color Balance controls. The White Balance
(Hard) operation is done programmatically by the camera firmware, so it changes R, G and B (Gain) of Sensor
Controls.
Note: It is not recommended to perform White Balance (Hard) when White Balance (Soft) is already performed. It
may cause the image colors distortion.
