Canon is developing a Hybrid Image Stabilizer (IS) lens for its digital SLR cameras to be released by the end of the year. The company says that it will be the world’s first optical Image Stabilizer that compensates for both angular camera shake and shift camera shake.
Angular camera shake refers to small rotational movements of the camera, while shift camera shake is movement of the whole camera in any of the three dimensions. Sudden changes in camera angle can cause significant blur in images taken during standard shooting, whereas blur caused by shift-based shaking, when a camera moves parallel to the subject, is more pronounced in macro and other close-up photography.
The new Hybrid IS technology incorporates an angular velocity sensor that detects the extent of angular camera shake that is found in all previous optical Image Stabilizer mechanisms, as well as a new acceleration sensor that determines the amount of shift-based camera shake. Hybrid IS also employs a newly developed algorithm that combines the output of the two sensors and moves the lens elements to compensate for both types of movement. Hybrid IS dramatically enhances the effects of Image Stabilizer especially during macro shooting, which is difficult for conventional image stabilisation technologies.
Canon says that it's working on interchangeable SLR camera lenses featuring the Hybrid IS technology, and is hoping to include it in a wide range of products.
