Evaluation system for camera shake and image stabilizers

Various optical image stabilizers for reducing camera shake have been developed in many camera manufacturers, however, it has not been known exactly how effective they work for cancellation of the camera shake. We developed a novel system for analyzing behavior of camera shake and evaluating effectiveness of image stabilizers quantitatively. It consists of the custom-made LED display for generating a high-speed VIDEO test pattern, PC software for detecting camera shake from the camera image of video test pattern, and the vibration table for simulating various camera shake. As well as introduction of this system, some evaluation results of image stabilizers are presented.
