5. Иштөө нускамалары

The Arducam IMX477 camera offers software-controlled focus, providing flexibility for various applications.

5.1 Focus Control

The motorized focus can be controlled in two primary ways:

• Manual Fine-tuning: Utilize keyboard arrow keys within compatible software applications to precisely adjust the focus.
• Автофокус: Implement autofocus functionality using provided OpenCV examples or custom scripts. This allows the camera to automatically adjust focus for optimal image clarity.

Refer to Arducam's software documentation and example code for detailed instructions on implementing and utilizing these focus control methods.
