Internal error during internal processing of the image
IS_CAP_STATUS_API_IMAGE_LOCKED
The destination buffers are locked and could not be written
to.
Possible cause/remedy
All destination buffers locked by the application
Release locked destination memory
Allocate more destination memory
Reduce the frame rate so that there is more time to
process the filled destination memory
IS_CAP_STATUS_DRV_OUT_OF_BUFFERS
No free internal image memory is available to the driver.
The image was discarded.
Possible cause/remedy
The computer takes too long to process the images in the
uc480 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)
IS_CAP_STATUS_DRV_DEVICE_NOT_READ
Y
The camera is no longer available. It is not possible to
access images that have already been transferred.
Possible cause
The camera has been disconnected or closed.
IS_CAP_STATUS_USB_TRANSFER_FAILED
The image was not transferred over the USB bus.
Possible cause/remedy
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
IS_CAP_STATUS_DEV_TIMEOUT
The maximum allowable time for image capturing in the
camera was exceeded.
Possible cause/remedy
The selected timeout value is too low for image capture
Reduce the exposure time
Increase the timeout

Returns the total number of errors occurred since
the last reset.
