Canon develops new Hybrid Image Stabilizer technology
by Wern Shen (Lowyat.net)
Shaky hands are the bane of all (amateur) photographers, but with the help of image stabilization, the effects can be effectively minimized. However, camera producers Canon don't seem content with the current technology level of today's image stabilizers and have developed an enhanced hybrid image stabilizer that not only compensates for angle camera shake, but also helps to reduce the adverse effects of shift camera shake too.
From the press release:
The Hybrid IS is the answer to camera users’ woes with several different preventative methods and corrective procedures. It compensates 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.
The new Hybrid IS technology incorporates an angular velocity sensor that detects the extent of angle-based shaking and 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 synthesizes information from the two sensors to make optimal adjustments, thereby dramatically enhancing the effects of image stabilization during shooting, including macro shooting, which had proven difficult for conventional image stabilization technologies.

Canon Developes World’s First Image Stabilizer
Hybrid Image Stabilizer to compensate for two types of camera shake
KUALA LUMPUR, 22nd July 2009— Canon Marketing (Malaysia), a global leader in photographic and digital imaging solutions, announced today the development of Hybrid Image Stabilizer (IS), the world’s first* 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 2009.
The Hybrid IS is the answer to camera users’ woes with several different preventative methods and corrective procedures. It compensates 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.
History of Excellence
Canon began researching methods to compensate for camera shake in the 1980s, and in 1995 launched the EF 75-300mm f/4-5.6 IS USM, the world’s first interchangeable SLR camera lens to feature a mechanism that compensates for optical camera shake. Since then, the company has continued to produce a variety of interchangeable lenses with image stabilization capabilities, and boasts a total of 21 such lenses in its current product lineup.
Solution to Camera Shakes
Canon’s newly developed Hybrid IS technology optimally compensates for angle and shift camera shake. Sudden changes in camera angle can significantly alter 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 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, including macro shooting, which had proven difficult for conventional image stabilization technologies.
Canon is actively engaged in ongoing research and development of interchangeable SLR camera lenses incorporating Hybrid IS technology, and is aiming for the early commercialization and inclusion of the lenses in a wide range of products.
