Canon might be planning to bring catadioptric 'mirror' lenses back from the dead. A new Canon patent spotted in Japan describes a 400mm F5.6 catadioptric lens that would use a variable density ‘electrochromic’ filter to 'stop down' the lens.

Olympus has patented a technology that records polarization information on the sensor itself, giving the effect of a polarizing filter but without the light cost. The patent is for a two-layer sensor that records color and brightness information on the top layer, just like a conventional sensor, but then has a second layer that captures information about the polarization of the light arriving at the camera.

Sony has patented the design of a series of bright zoom lenses, including a roughly F1.8-2.8 lens that would give 26-100mm equivalent coverage on a 1"-type sensor. The designs suggest the company intends to further develop its RX range of compacts. Such a lens would allow for a camera that made better use of its comparatively large sensor, even at the long end of the zoom. Learn more

Fujifilm has filed a patent for an image sensor that uses a novel layout, with green and clear rectangular pixels which are larger in area than their neighboring blue and red pixels. The idea behind it is apparently to reduce luminance noise at the expense of color noise, on the grounds that the human eye is less sensitive to the latter. Learn more

Patent for "sport glasses" allows users to take phone calls and listen to music.
It's an open secret that many compact cameras are produced by OEMs - companies that produce large numbers of products that are then sold under other brand names. There are also consumer-grade zooms from big name manufacturers that look much alike (we know for a fact that third-party makers commonly create lenses for the bigger brands). But we were still surprised to read about Sigma's latest patent for a 75mm F1.8 prime lens...
Another interesting patent has been discovered by Japanese blogger Egami, which shows a new method devised by Canon to adjust the shape of meniscus lens that seems different from the more straightforward method used by competitors. Canon's method uses the same 'electrowetting' principle as existing designs but does so to create a series of pumps, allowing faster and more precise control over the resultant lens.

Canon has patented a color-sensitive multi-layered sensor design, showing the company is still pursuing the technology. Like Sigma's Foveon chips, the multi-layered design allows each of the sensor's pixels to capture color information without the need for colored filters. The patent, discovered by the Japanese Engineering Accomplishment blog, suggests a system to promote resonance within the sensor, in an attempt to make the lower layers of the sensor more sensitive.
