Capture errors
This group box provides detail information on errors that occurred during an image capture process:
Error
Description
#
API no destination
memory
There is no destination memory for copying the finished image.
1
API conversion failed
The current image could not be processed correctly.
2
API image locked
The destination buffers are locked and could not be written to.
3
DRV out of buffers
No free internal image memory is available to the driver. The image was
discarded.
4
DRV device not
ready
The camera is no longer available. It is not possible to access images
that have already been transferred.
5
USB transfer failed
The image was not transferred over the USB bus.
6
DEV timeout
The maximum allowable time for image capturing in the camera was
exceeded.
7
ETH buffer overrun
Not applicable to USB cameras.
8
ETH missed images
Not applicable to USB cameras.
9
#
Possible cause
Remedy
1
Not enough destination memory allocated
or all destination buffers locked by the
application
Reduce the frame rate so that there is more time to
process the filled destination memory
2
Internal error during internal processing of
the image
-
3
All destination buffers locked by the
application
Reduce the frame rate so that there is more time to
process the filled destination memory
4
The computer takes too long to process the
images in the A
PI
(e.g. colour conversion)
Reduce the frame rate so that there is more time to
process the filled image memory of the driver
Disable
resource-intensive
API
image
pre-
processing functions (e.g. edge enhancement,
colour correction, choose smaller filter mask for
software colour conversion)
5
The camera has been disconnected or
closed
-
6
Not enough free bandwidth on the USB bus
for transferring the image
Reduce the pixel clock frequency
Operate fewer cameras simultaneously on a USB
bus
Check the quality of the USB cabling and
components
7
The selected timeout value is too low for
image capture
Reduce the exposure time
Increase the timeout
