Focus helper

[ExtReMLapin]

Could it be possible to have some kind of "focus helper" ?

Let me explain.

On openscan mini, when we scan a non-spherical object, (a tall one, for example) we might need to adjust the focus before starting the scan and during it.

Could it be possible to have :

• some kind of warning telling us to adjust the focus (right before starting the scan)

• Focus helper tab, it gives a focus score using a zone at the middle of the image, display this score on the web page instead of the preview image itself so we can know when the focus is the best (as downloading the image on each frame is slower than just the score).

• Mid scan, if focus score goes bellow a threshold, propose the user to readjust the focus.
