Canon Patent Application: Sensor Protection Assembly

Every now and then we post a patent application and make mistakes on assumptions with the Japanese translations.  This is one of those times, as noted to us, this patent application is not a shutter assembly but another assembly that Canon is looking at simply covering the sensor without using the delicate shutter (or in the case of cameras with global shutters).

We will strive to do better than we apologize for the mischaracterization and reporting on the patent application.
