Code Sample
Description
is_GetImageInfo() provides additional information on the images you take. The function returns a
timestamp indicating the time of image capture, and the states of the camera I/Os at that point in
time. To get information on the last image that was taken, call is_GetImageInfo directly after
receiving the IS_FRAME event.
Using the function with USB DCx camera cameras
The u64TimestampDevice timestamp returns the time when image data transfer to the PC was
completed.
The _UC480TIME structure returns the timestamp (with a resolution of 1 ms) synchronized with the
PC system time.
Image buffers that are part of a sequence need to be locked using is_LockSeqBuf() . This is
important to ensure correct assignment between image data and image information. Otherwise, it
may happen that an image buffer is filled with new image data. In this case, the image information
will not match the image data any more.

nImageBufferID
ID of the image buffer for which information is requested
pImageInfo
Pointer to a _UC480IMAGEINFO type structure to which the information will be
written
