Canon recently announced the development of Hybrid Image Stabilizer (IS), a new optical image stabilization technology that compensates for both angle camera shake and shift camera shake. The technology will be featured in interchangeable single lens reflex (SLR) camera lens planned for commercial release before the end of this year.
Over the years, several different preventative methods and corrective procedures have been introduced to compensate for errors caused by camera shake, which occurs when a camera moves while its shutter is open and its image sensor is exposed to light.
Canon’s newly developed Hybrid IS technology optimally compensates for angle and shift camera shake. Sudden changes in camera angle can significantly affect images taken during standard shooting, whereas shift-based shaking, which occurs when a camera moves parallel to the imaging scene, is more pronounced in macro photography and other close-range shooting.
The new Hybrid IS technology incorporates an angular velocity sensor that detects the extent of angle-based shaking and is found in all previous Canon 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 synthesizes information from the two sensors to make optimal adjustments, thereby dramatically enhancing the effects of image stabilization during shooting.
