Besides the “manual” setting of the white balancing ratios, the camera might compute them
automatically based on an actually acquired image. To instruct the camera to compute the new
ratios, switch the Automatic White Balance feature to Once (the default value of this enumeration
is Off). As soon as switched to Once, the camera will automatically evaluate the acquired image
and compute new white balancing factor — considering, that the acquired image is color neutral,
i.e. suitable for white balance calibration. When computed, the Automatic White Balance will switch
back to Off and the newly computed values will be available through Balance Ratio Selector/Balance
Ratio. Of course, the new values will immediately become effective. When required, the process
should be repeated again.
LvHDevice hDev; // open the device to get the handle
// select the "white balance" LUT mode
LvSetEnum (hDev, LvDevice_LvLUTMode, LvLUTMode_BalanceWhite);
// trigger computation of new white balance factors
LvSetEnum (hDev, LvDevice_BalanceWhiteAuto,
LvBalanceWhiteAuto_Once);
// when finished, it switches back to LvBalanceWhiteAuto_Off
// and new balance ratios are immediately applied
select the "white balance" LUT mode
write_enum (LvLUTMode, BalanceWhite)
// trigger computation of new white balance factors
write_enum (BalanceWhiteAuto, Once)
// when finished, it switches back to LvBalanceWhiteAuto_Off
// and new balance ratios are immediately applied
