More Canon patent applications.
A patent application doesn’t mean the described technology will go into production soon. Some Canon patent applications which in our opinion might go into production:
- Patent application describing how to improve burst rate by compressing raw files
- Patent application describing a new way to review photos from a sequential shot
- Patent application that describes technology to improve wireless communication while reducing power consumption
- Patent application to spot and reduce moire artefacts in image data
- Patent application for weather sealed lens adapter
