What is maximum Z position(height), to get the crisp preview of a phone screen below openmv camera ?


I am trying to setup OpenMV camera in a height(this case: 13 cm). I tried also other different heights to check if I can see the preview of a phone screen CRISP. But no Success !!

I also adjusted the focus, set framesize to VGA but attached is the best what I can see.

Any insights on how can or if it’s possible to see clear preview or at least have a snapshot where the text of icons are clearly visible ?


Hi, the camera res doesn’t allow for you to see all the detail in that screen. You may zoom in on one area of the screen, but not all.

What’s the application?

Did you save that image from a script or screenshot the IDE preview ? Note the IDE preview is JPEG compressed (small text will be destroyed).
