Timeout Values for Image Capture

When you call

is_FreezeVideo()

is_CaptureVideo()

, the timeout value for the image

capture is determined from the

Wait

parameter. If no image arrives within this timeout period, a

timeout error message is issued. Under Windows, a dialogue box is displayed if you have enabled
error reports (see

is_SetErrorReport()

). Information on the error cause can be queried using

is_GetCaptureErrorInfo()

The following table shows the effect of the

Wait

parameter depending on the image capture mode:
