Canon Patent Application: IBIS + IS stablization

In this latest IBIS (In body image stabilization) and IS (lens based stabilization) patent application, Canon details methods to improve the accuracy of the IBIS + IS stabilization.

While I know some will want to see IBIS on your favorite DSLR, most of these patents discuss high speed communication between the camera and the lens, something that may be impossible with the EF mount, and is one of the reasons Canon went with the RF mount.

Both the camera and the lens have motion velocity sensors that manage to move the optical elements or image sensor, and they communicate which each other has each filter the movements depending on a high pass or low pass filter to decide what stabilization is used to combat the movement.
