8 Applications
#
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 buffers
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 buffers
4
The computer takes too long to process
the images in the uEye 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)
5
The camera was disconnected or closed
-
6
Not enough free bandwidth for image
transfer available on the USB bus
· 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 captre
· Reduce the exposure time
· Increase the timeout
8
The data rate of the sensor is too high
· Reduce the pixel clock frequency
· Reduce the frame rate
· Reduce the AOI
9
The camera's frame rate is too high or
the bandwidth on the network is
insufficient to transfer the image
· Reduce the frame rate
· Increase the value for the receive descriptors in the
network card settings
