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 |
The sensor transfers more data than the internal camera memory of the GigE uEye can accommodate. |
8 |
ETH missed images |
The GigE uEye camera could neither process nor output an image captured by the sensor. |
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 uEye API (e.g. color 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, color correction, choose smaller filter mask for software color 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 |
8 |
The selected data rate of the sensor is too high |
•Reduce the pixel clock frequency •Reduce the frame rate •Reduce the image size |
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 |
Camera image buffers
If you are using a GigE uEye camera, this group box displays the number and utilization of the camera's image buffers. If the image buffers are utilized to full capacity, frames might be lost.
Resent packets
With GigE uEye cameras, this field displays the number of network packets that were retransmitted due to data loss. This value indicates the quality of the network connection.
