Canon continues to work on sensor-based image stabilization, which is a feature we expect to see in the next major EOS R camera body release. Canon has been working on getting the in-body stabilization to work with its in-lens stabilization technology.
This USPTO patent takes things one step further, as Canon appears to be working to get three stabilization systems working together.
These three systems would be:
- In-body or image sensor stabilization
- In-lens image stabilization
- Electronic image stabilization
Canon News breaks down what this patent likely means:
So what's the goal of all this? The gist is they want to improve image stabilization when the various parts of the camera system are working together to stabilize video recording. What Canon is stating (I believe) is that as the shutter speed increases, the amount of shake that the optical / image sensor handles increases, and the frequency of shake that the electronic image stabilization corrects decreases. This leads to better image stabilization when using slow shutter speeds to shoot video.
