I have the quad-camera board and the four cameras i just got, and can use libcamera-still to do an autofocus (though for some reason in libcamera v 0.0.11 i can no longer use picamera2 in scripts?)
but im confused about the camera focusing. I know all the cameras are synced and whatever values get set for one affect them all. but when it is autofocusing, which camera is it looking at? (or is it averaging all the cameras?)
Yeah, so like normally im guessing when you use autofocus in single camera mode, it uses the camera and an algorithm to scan through the focus values until an area of the image (probably the center of the image) has sharp lines and is “in focus”
when you have the quad camera setup, does it just do autofocusing on one camera and set all cameras to that same focus? does it do the algorithm on all cameras and average it? how does it work?
the same errors as all the poor folks over here
trying to deal with your libraries getting updated, but lacking the basic commands or documentation for how to use them. We all apparently have to manually downgrade to v10 i guess?
but they are pointed at different things in focus.
is the system:
A) taking an average of the focus of all four cameras?
B) use one camera as a "primary camera?
C) something else?
i’ve been testing myself, but can’t really figure out what’s going on. If i had to make a guess, it seems like it is doing something like A), or treating all four cameras as ONE image, and if a certain amount of the total pixels are in focus, the system things it has reached “focus”
so it focuses on the corner of each of the four cameras?
is there a way to switch to one camera, run autofocus, read the focus value, and then switch to 4 camera mode and have them all manually focus to that?
