Canon Patent Application: Smartphone Telelphoto

Last year around Christmas, we found a model design for a smartphone device that Canon was looking at doing, and finally, we have found the actual patent application for this device.

We know that Canon is looking for novel devices as they have added quite a few to their inventory.  Canon isn't one to stand still even if the innovation may not be what photography enthusiasts desire.

Canon shows a variety of positions for the camera device, but essentially they are looking at providing a high-powered zoom for smartphones.

I could see this being a good idea, because while "hybrid" zooms exist (and a few examples of true zooms), the sensor size has to be very limited, and there's simply not much room for optics, making them dimmer than necessary, even with folded telephoto optics.  With such a design, Canon has much more freedom to provide better optical quality, better image quality, and also better stabilization into the picture for smartphones.  Something that probably won't happen in the smartphone space unless major breakthroughs in optics occur.

How to view Japan Patent applications.

Unfortunately, there's no direct way of linking to the patent application (sad!) however, this is the easiest process to view a japan patent or application.

  1. Go to the Japan Patent Office search page.
  2. If it's a patent application (they are usually in the format of Year-Number ie: 2017-011300) then type the patent application number into the second field down from the top where it says publication of patent application. 
  3. Click on search.
  4. Then click on the patent application number link, and there's the patent application!
