Description

Steps to reproduce:

Publish Image and CameraInfo using CameraPublisher.

Observed & Expected:

Image frame rate (as measured by ros2 topic hz) is around 8. Expected: equal to the CameraInfo frame rate.
CameraInfo frame rate (as measured by ros2 topic hz) is around 16. Expected: equal to the Image frame rate.

Questions:

Could it be that any other Image fails to be published?
Could it be an issue with ros2 topic hz?

Start by reproducing the report with CameraPublisher and compare Image and CameraInfo using ros2 topic hz. Determine whether Image messages are being dropped or ros2 topic hz is reporting an incorrect rate; done means identifying the cause and confirming matching measured rates.
