This feature can be used to put the camera in to (and out of) a ‘special’ mode of operation. See the chart below for the definition of each of these special modes. This feature may not be set while the camera is streaming images. Furthermore, if the camera is to be placed in a special mode of operation, it is recommended that this feature be used immediately after the camera is PxLInitialize'ed, as placing the camera in a special mode may have implications of other features (including the limits of those features).
|IIDC Name||API Name||Description|
|N/A||FEATURE_SPECIAL_CAMERA_MODE_NONE||No special camera mode - the camera behaves normally (as described in the PixeLINK documentation)|
|N/A||FEATURE_SPECIAL_CAMERA_MODE_FIXED_FRAME_RATE||The camera's frame rate is not controllable directly. Rather, the camera will chose a frame rate based on the setting of the Region of Interest (ROI). This special camera mode can accommodate faster frame rates than can be otherwise achieved while in its normal mode of operation.|
