IDS uEye series User Manual page 85

# Possible cause
1 Not enough destination memory
allocated or all destination buffers locked
by the application
2
Internal error during internal processing
of the image
3 All destination buffers locked by the
application
4 The computer takes too long to process
the images in the uEye API (e.g. colour
conversion)
5 The camera was disconnected or closed -
6 Not enough free bandwidth for image
transfer available on the USB bus
7 The selected timeout value is too low for
image captre
8 The data rate of the sensor is too high
9 The camera's frame rate is too high or
the bandwidth on the network is
insufficient to transfer the image

Remedy
· Reduce the frame rate so that there is more time to
process the filled destination buffers
-
· Reduce the frame rate so that there is more time to
process the filled destination buffers
· 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)
· Reduce the pixel clock frequency
· Operate fewer cameras simultaneously on a USB
bus
· Check the quality of the USB cabling and
components
· Reduce the exposure time
· Increase the timeout
· Reduce the pixel clock frequency
· Reduce the frame rate
· Reduce the AOI
· Reduce the frame rate
· Increase the value for the receive descriptors in the
network card settings
