/**************************************************
this is the second version of release ASI Camera ASIs
any question feel free contact us:sam.wen@zwoptical.com

here is the suggested procedure to operate the camera.

--> ASIGetNumOfConnectedCameras
----> ASIGetCameraProperty for each camera

--> ASIOpenCamera
--> ASIInitCamera
--> ASIGetNumOfControls
----> ASIGetControlCaps for each contronl and set or get value from them

--> ASISetROIFormat

--> ASISetCameraMode

--> ASIStartVideoCapture

//this is recommended to do in another thread
