Here is an interesting Canon patent for a lens featured on a fixed lens full…
Since a few weeks it seems anyone is flooding the web with patent applications filed by Canon, going from obscure to unintelligible (to me). Patents are a way companies have to put a protective seal on their research, independently from the fact if they plan or not to release their proprietary technology.
I’m trying to find patents that actually have a chance to made it into production, like this patent to improve burst rate by compressing raw files, or this one describing an improved way to review photos from a sequential shot.
Similar immediate and real-world usefulness can be found also in Canon patent EP20170176556, which describes system and method to save power during a wireless communication, i.e. how to achieve both an improvement in operability and suppression of battery consumption. Something that surely matters to most photogs. It sure matters to me.
This is important, this is real world, and this may get soon on a camera (could be the EOS 7D Mark III).
The patent’s abstract:
A communication apparatus capable of achieving both of improvement in operability and suppression of battery consumption. A camera as the communication apparatus wirelessly communicates with one of a plurality of external devices including a remote controller and a smartphone. The state of the camera is switched between an operating state and a power-saving state in which power consumption is smaller than in the operating state. In the power-saving state, when a connection request is received from the remote controller as a device for non-continuous connection, a process for establishing a connection with the remote controller is started, and the camera is shifted to the operating state. In the power-saving state, when a connection request is received from the smartphone as a device for continuous connection, a process for establishing a connection with the smartphone is started, and the camera is not shifted to the operating state.
