frame rate 90 but republish both camera_info and image at a lower rate

[altineller]

Hello,

Could it be possible to publish image and camera info at a lower speed than frame rate? Say capture at 90hz and publish them at 10hz, without destroying the syncronization between image and camera info?

This would be highly useful :)

The closest thing we have is setting the capture rate to 10hz and manually setting the shutter speed lower. If you can figure out something better, it would be much appreciated.
