IMX477 – Motorized Focus Camera


This Arducam IMX477 High Quality motorized focus camera module integrates a motor that could be controlled by software for a smarter focus, and you will no longer focus the camera by screwing the lens with your bare hands.
So how has software focus control made it more convenient? Here is an idea: Arducam provides you with an example program to control the focusing motor with keyboard keys, so you can focus the camera remotely with precision in an intuitive way. In another example powered by OpenCV, algorithms are used to control the motor and achieve autofocus.
Other than its motorized focus, it offers the same picture quality and camera controls as the Raspberry Pi High Quality camera.
