Digital Image Stabilization Controller Design

This thesis designs a digital image-stabilized controller based on the MCU. It describes the basic structure and the operational principle of the image-stabilized device. The controller is mainly applied to control the coaxial and mounted TV guidance of frame which has the character of compact frame and easy controlling.The TV guidance consists of three main parts: imaging and image-stabilized device, controller and image processor. The controller is made up of precession circuit and rotation circuit. The thesis depicts the operational principle and the software and hardware design of the controller. It adopts the MCU which is STC12C4052AD and designs the digital image-stabilized controller.The software design of the controller adopts the module method. It includes three modules: A/D sampling, PWM driving and rotating control. Do the system debugging aiming to the digital image-stabilized controller after having completed the design processing of the control circuit board. The debugging result indicates: the digital image-stabilized controller runs well and performs kindly as expected, which proves the feasibility of PWM driving.
