StillColor Settings
The StillColor settings dialog box, shown in Figure 5-8, lets you adjust
basic StillColor settings. See Appendix B, StillColor, for more
information on StillColor and color image acquisition parameters.
Note:
This dialog box is available only if you enable StillColor Mode on the
Operating Mode tab. In StillColor Composite mode (PAL and NTSC
cameras), you can adjust all settings in this dialog box. In StillColor RGB
mode, you can adjust only the Image Representation and Averaging
parameters.
Figure 5-8. Basic StillColor Settings
Basic StillColor settings include:
•
Brightness (IRE)—This parameter adjusts the brightness of the
acquired picture. Brightness is valid only in composite mode. The
unit is IRE, which is a percentage of the white level. The default
value is 0, which corresponds to no correction.
•
Contrast—This parameter adjusts the contrast of the acquired
picture. Contrast is valid only in composite mode. The default
value is 1.00, which corresponds to no correction. A value of 1.25
corresponds to an increase of the contrast by 25%.
•
Saturation—This parameter adjusts the saturation of the acquired
picture. Saturation is valid only in composite mode. The default
value is 1.00 corresponding to no correction. A value of 1.25
corresponds to an increase of the saturation by 25%.
