View Full Version : No Autowhitebalance with Sony WDM-driver

July 31, 2002, 09:41:40
The Sony WDM-driver works very well except that I can not use the autowhitebalace and one-push-whitebalance settings.
The manual settings of the WhiteBalanceR/B values work. I can get and set these values: hr=pVideoControl->Set(VideoProcAmp_WhiteBalance_B,m_wbb,VideoProcAmp _Flags_Manual);
But when I try to use hr=pVideoControl->Set(VideoProcAmp_WhiteBalance_B,m_wbb,VideoProcAmp _Flags_OnePush);
or hr=pVideoControl->Set(VideoProcAmp_WhiteBalance_B,m_wbb,VideoProcAmp _Flags_Auto);
the HRESULT value is 0 but nothing happens. I am working with DirectX8, Windows2000-SP2 and a Sony DFW-SX900 camera.
Do you have an idea what´s wrong ?

If you want to use the auto WB feature you have to select an exposure time equal or less than 1/32 sec.
The Sony Add-On for IC solves this problem in its demo application.

Please note that this is a driver problem.
