Decoupling the image acquisition from the Image Processing

[Tom Line]

Is there any reason not to decouple the image acquisition from the image processing?

I'm really not interested in seeing the information on my dashoard as far as the tracking goes - I'm much more interested in seeing the dashboard images as quickly as possible for our drivers.

So my thought was that I could save the image to a global variable when it comes from the camera and feed that global to the dashboard.

On the side, have a second global (call it the image processing global). Save a camera image into that image-processing global, process the image information, then allow a new image to be saved from the camera into the image-processing global to do the processing on the new image.

I believe that will get me maximum dashboard framerate while still allowing the image processing to run as fast as it can. Are there any issues with that?
