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 Cameras
The u64TimestampDevice timestamp returns the time when image data transfer to the PC was completed.
The UEYETIME structure returns the timestamp (with a resolution of 1 ms) synchronized with the PC system time.
Attention
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.
