Center focus does not seem to do anything #1

Closed ScruffySoft closed 3 years ago

ScruffySoft commented 3 years ago

I get a picture at 1280x720 and 20 fps, but the "center" just overlays a red cross and doesn't seem to do anything. Is it supposed to do something else? Also, "focus" doesn't seem to do anything at all except twinkle a part of the screen. Is there a way of controlling these functions?

Center just shows you the exact center of the frame. This is used commonly with DSLRs to aid in framing a subject.

Focus shows you what the focus peaking algorithm considers to be in focus. This is an aid to help you to determine what is in focus, since it can be hard to do on a small screen like a phone etc. If you adjust the lens focus you will see the twinkle move around the frame.
