Remarks

● After calling MV_CC_CreateHandle , call this API to set image data callback function.

● There are two available image data acquisition modes, and cannot be used together:

1. Call MV_CC_RegisterImageCallBackForBGR to set BGR24 format image data callback

function, and then call MV_CC_StartGrabbing to start acquiring. The acquired image data is

returned in the configured callback function.

2. Call MV_CC_StartGrabbing to start acquiring, and then call MV_CC_GetImageForBGR

repeatedly in application layer to get frame data with BGR24 format. When getting frame data,

the frequency of calling this API should be controlled by upper layer application according to

frame rate.

● This API is not supported by CameraLink device.
