LONG |
The property value (operation data) is a LONG that specifies a camera's brightness setting. This value is expressed in IRE units multiplied by 100 for NTSC sources. For non-NTSC sources, the units are arbitrary, with 0 representing blanking and 10000 representing pure white.
Remarks
The Value member of the KSPROPERTY_VIDEOPROCAMP_S structure specifies the brightness.
Brightness is also known as the black level. Modifying the brightness setting shifts the entire video signal equally for all luminance values.
Every video capture minidriver must define a range and default value for this property. The required range must be -10000 through +10000. The default value must be 750 (7.5 IRE).
