Handheld camera stabilizer

The camera stabilizer is the supporting device for installing and fixing the camera. It is divided into fixed and electronic ones. The electronic camera stabilizer is suitable for scanning and monitoring a large area, and it can expand the surveillance range of the camera. The high-speed profile of the electronic camera stabilizer is achieved by two executive motors which receive signals from the controller to give accurate position.

Based on MindMotion’s MM32SPIN422C microcontroller, the motor control scheme takes MM32SPIN422C as its main control:

- Highly integrated solution with MOSFET and LDO integrated in the chip

- Embed dedicated motor control modules like divider, comparator and operation amplifier

- Changes are seen in the actual dynamic sampling environment of the six-axis sensor with the dynamic calibration of the scientific algorithm

- PWM motor’s accurate control allows shooting balance and anti-shake
