I have a diy Microscope camera which works great in Jitter. The camera is mountet on a linearaxis with steppermotor to control the focus. I need now to analyse the image in jitter to detect the focus and stop the camera at the right distance.

What i am search for is how to get jitter to know if the image is in focus or not.

One suggestion: The easy method for autofocus is about finding the maximum amount of edges in the image. jit.sobel is an edge detection algorithm that will produce the most edges/brightest output when the image is focussed. You'll obviously need to massage its output to control the camera servo.

Jit.sobel is a start. maybe combine with cv.jit.perimeter.

Distance senore, yes i thought about, but the range is within a millimeter. Do you know a sensor which works in that range ?
