Structure used to uniquely identify frames in the camera.
Please note that this information is generated by the low level device driver. While the information is accurate for slower acquisitions and most legacy CCD cameras, the timestamps are still obtained from the operating systems. For that reason the timestamps may not always represent the time of actual, in-camera acquisition. This is especially true for fast CMOS cameras that implement an internal frame buffer. Such cameras often report both the BOF and EOF timestamps as identical numbers with the readout time reported as 0. For accurate hardware timestamps please see Embedded Frame Metadata feature.
PVCAM_FRAME_INFO_GUID _TAG_FRAME_INFO::FrameInfoGUID |
int32 _TAG_FRAME_INFO::FrameNr |
Frame number, 1-based.
int16 _TAG_FRAME_INFO::hCam |
Handle of the camera that sent this structure.
int32 _TAG_FRAME_INFO::ReadoutTime |
Frame readout time.
long64 _TAG_FRAME_INFO::TimeStamp |
Frame EOF (end-of-frame) timestamp.
long64 _TAG_FRAME_INFO::TimeStampBOF |
Frame BOF (beginning-of-frame timestamp.
