This VB example displays the actual frame rate of the camera.
Private Sub ActiveUSB1_FrameAcquired()
Label1.Caption = ActiveUSB1.GetFPS
This method returns the actual frame rate of the camera. Note that the actural frame rate may differ from the acquired frame rate. ActiveUSB calculates the actual frame rate using the frame timestamps. If the camera doesn't support timestamps, the frame rate is calcualted based on the arrival of the video packets to the system memory.
