Abstract :
A compact and low-cost automatic image stabilization (AIS) system for camcorders has been developed. The new technology used in the system consists of a vibration-type gyro sensor with vibration feedback, an AIS control system using observer theory and an intentional camera motion discrimination algorithm. This is the first AIS system developed for consumer use and applied to camcorders with an image fluctuation suppression rate as high as -18 dB (1 Hz) or -38 dB (10 Hz)
