Capture errors
This group box provides detail information on errors that occurred during an image capture process:
There is no destination memory for copying the finished image.
The current image could not be processed correctly.
The destination buffers are locked and could not be written to.
No free internal image memory is available to the driver. The image was
discarded.
The camera is no longer available. It is not possible to access images
that have already been transferred.
The image was not transferred over the USB bus.
The maximum allowable time for image capturing in the camera was
exceeded.
Not applicable to USB cameras.
Not applicable to USB cameras.
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
Internal error during internal processing of
the image
All destination buffers locked by the
application
Reduce the frame rate so that there is more time to
process the filled destination memory
The computer takes too long to process the
images in the API (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)
The camera has been disconnected or
closed
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
The selected timeout value is too low for
image capture
Reduce the exposure time
Increase the timeout
