Camera FPS - what is the right setting?

[pgaston]

I'm using the advanced framework.   I can spin the image processing part of the loop at, say 5-10 fps (maybe more with tricks like decimation, etc.)   

How fast should the camera fps be set?   10?   30?   Is there overhead on having it at 30fps while I'm processing at say 5fps?    (If no overhead, I'd assume 30fps so the processing loop gets the latest available image, right?)

Thanks!

(Sorry - but I'm still weak on this dataflow-esque linkage model...)

Hi,

You only need as many frames from the camera as you're actually going to process, so if you are running your processing loop at 5 hz, there isn't any reason to run the camera faster than 5 fps.
