How do you focus a PI camera?
To adjust focus, pinch the indentations with the pliers (gently), then give a small amount of torque (just enough to break the thin glue that sets factory focus). Turn back and forth in small increments while taking pictures to confirm the correct focus.
How does mobile camera autofocus work?
Essentially, it’s an auto-focus system based on trial-and-error. The lens on your camera phone is moved back and forth until the position of maximum focus is found for the object. In order to determine when an image is in focus, your smartphone uses an algorithm based on measuring the contrast.
What is autofocus in mobile camera?
Autofocus (AF) on smartphones is the process of determin- ing how to move a camera’s lens such that certain scene content is in focus. The underlying algorithms used by AF systems, such as contrast detection and phase differencing, are well established.
How does autofocus work on a Raspberry Pi camera?
To learn more about autofocus with Raspberry Pi camera modules, we recommend you read Raspberry Pi Camera Autofocus: The Complete Guid e. The standard pi camera is fixed focus lens, some of them are glued which cannot be adjusted by users, and some of them are not glued which can adjust the lens focus manually.

Is there a camera module for the Raspberry Pi?
The ArduCAM team now designed motorized control focus 5MP and an 8MP camera module for Raspberry Pi series boards to address this problem. Now the autofocus function is also implemented by the Arducam team, now the auto-focus demo source code is available on our GitHub.
Is the HQ camera on a Raspberry Pi?
Instead of having the image sensor in one package as the lens assembly, the IMX477 image sensor of the HQ camera is on the camera PCB. This leads us to two methods to design a Pi camera that support autofocus: We build a CCM with a focus motor inside, and then connect it to the Raspberry Pi Camera PCB.
