View Full Version : How to check auto whitebalance value ?

Is there any way to check what is the value of whitebalance, exposure, or gain when they are set to auto mode.

The point is, I want to react in my image processing accordingly to white balance changes. But I don't know how to check the value of this property when it is set to auto.

No, there usually is no way to receive the current values of properties, while they run on automatic. This depends on the used video capture devices.
However, you can use IC Capture and show the property dialog (right mouse click on the live video display) and click the "Update button" while the properties are set to automatic. If the values change, then you can check these properties in your application too.
