use MCaptureImageObserver , MCaptureVideoObserver , MDirectViewFinderObserver , and MClientViewFinderObserver which have callback functions which notify the client about availability of histogram data. These are sent when CCameraV2Histogram::StartHistogram() is called after CCameraV2Histogram::PrepareClientHistogramL(). If CCameraV2Histogram::PrepareClientHistogramL() is not called first then the callback returns KErrBadHandle.
Uid used to identify the event that the request for histogram has completed. A callback to MCameraObserver2::HandleEvent() will occur when the histogram data is ready to be retrieved. If a call to StartHistogram() is made without a previous successful call to PrepareHistogramL() then the callback returns KErrBadHandle.
