Abstract

A jitter correction method and a jitter correction apparatus are disclosed. The jitter correction method comprises: after the electronic device is connected to the jitter correction device, starting the magnetic field generating means to generate a magnetic field, and adjusting the integral center of gravity of the electronic device, the connecting member and the balance terminal connected to eachother by the force of the magnetic field on the balance terminal to maintain a balance between gravity and magnetic field force; obtaining an initial image when the balance terminal is at an initialposition and a detection image thereafter based on photoelectric detection; determining a motion mode and a motion amount of the balance terminal based on the difference when the initial image is different from the detection image; and adjusting a magnetic field based on the motion mode and the motion amount to restore the balance terminal to an initial position.

Description

technical field [0001] The present invention relates to anti-shake technology, more specifically, to a shake correction method and shake correction equipment based on photoelectric detection and magnetic levitation. Background technique [0002] Most of the current anti-shake technologies are used in camera equipment. Camera anti-shake technology mainly includes the following types: [0003] 1. Optical image stabilization (OIS), the basic principle is that the gyroscope in the lens detects a small movement, and the signal is sent to the microprocessor to immediately calculate the amount of displacement that needs to be compensated, and then through the compensation lens group, according to The shake direction and displacement of the lens are compensated, so as to effectively overcome the image blur caused by the vibration of the camera. [0004] 2. Sensor anti-shake (CCD / CMOS), the basic principle is to place the CCD on a bracket that can move up and down, left and right, ...
