Attempting to snap a picture with NI-IMAQ for USB in LabVIEW 8.0 using the following procedure.
1)I get the first enumerated camera, 2) open a session, with returned
string [0], 3) start a session, 4) snap a picture and 5) close
vi. My problem is that in step 4 with the IMAQ USB Snap.vi, I get
the following error.
--------
Error -1074396014 occurred at IMAQ USB snap.vi
The image passed is not valid.
Possible Reasons(s):
IMAQ Vision: (Hex 0xBFF60492) RT Video Out does not support displaying the supplied image type at the selected color depth.
--------
I give the snap.vi an Image in from rightclick->Create->Control
or rightclick->Create->Constant. The output image (on the
Front Panel) created by rightclick->Create->Indicator.
LabVIEW should insert the correct data structure to match the expected
input/output, and there is nothing I can that changes he color
depth. The GetImageInfo.vi reports that the camera is set up for
4 Bytes Per Pixel, with the rectangle 352x288.
Also the error message refers to RT Video Out, but I am using USB. This distinction is significant in NI Vision Assistant.
