I see tilt-shift lenses mentioned as one possible example, that could be a surprise! I can see the click bait site headlines now, "Canon Patents IS for Tilt-Shift Lenses"
Apparently, the invention makes it possible to stabilize larger amounts of movement, which might be a advantage for long lenses, as well as video where the videographer is moving. Being able to stabilize a tilt - shift lens is interesting, I'm not sure that's needed.
"The present invention relates to an image shake compensator constituted so that a high definition image might be acquired using a plurality of operating means for changing the image formation position to the image formation face of a variable vertex angle prism,
a shift lens, etc., and a control method for the same.
[Background of the Invention]
[0002]
The image imaged with imaging devices, such as a digital camera, holds a camera body at the time of image imaging, for example, when a user's hand shakes, it may sway to an object image and what is called a shaking hand may produce it. For this reason, the correcting function which corrects the image shake of an object image which appears in a captured image by vibration added to the camera body is included in the digital camera. As a means to correct such an image shake, optical image shake compensating processing and an electronic image shake compensation process are known conventionally, and it realizes by canceling an image shake by these processings.
[0003]
An optical image shake compensation process detects vibration added to the camera body with the angular velocity sensor etc., moves the image shake correcting lens provided inside the photographing optical system which forms an object image according to this detection result, and changes the optical axis direction of this photographing optical system. It is the processing which moves the image imaged by the light receiving surface of an image sensor, and corrects an image shake by this. Electronic image shake correction is processing which performs an image processing to a captured image and corrects an image shake pseudoly.
[0004]
By the way, since the image shake compensator of the conventional imaging device had a case where the delay of the flattery nature of a driving part arises to a target drive amount, and sufficient shake compensating effect is not achieved when driving a correction optical system, and the narrow range of shake compensating, there were two problems that sufficient shake compensating effect was not achieved.
[0005]
To such a problem, it has two shake correction optical systems, and the method of switching the lens driven, respectively by the case where a focal distance is a looking-far or wide angle side is proposed by the Patent document 1."
