Apple has been awarded a patent for a system that allows for the camera on an iPhone to be disabled remotely via an infrared signal. The technology could be implemented in concert venues, classified areas or any other location where photography is not allowed. Read more
Canon has applied for a viewfinder design patent that combines both optical and electronic displays in a DSLR style system. Read more
Apple has patented a design for a very small camera module that uses a curved sensor and an array of lenses.
Global tech giant Google could be joining the camera business if a patent it was awarded this month is anything to go by. Filed in June 2014 and just approved on the 12th January this year, the patent issued by the United States Patent and Trademark Office is for a design for a folding camera that's hinged in the middle like a clamshell mobile phone.

A newly published Apple patent application describes a methodology for rendering 3D images on a 2D display.
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.

Apple has patented a super resolution camera mode that uses the same image shift concept as some Olympus and Pentax cameras.
Apple is aiming to patent a system that allows a smartphone camera's main sensor to capture images from different directions.
Apple is looking at ways of incorporating optical image stabilization systems and zoom lenses into mobile devices by using a mirror assembly.
It's not uncommon for a company to patent technologies that might be incorporated into products at some point, though the company might not have any plans to use it in the immediate future. Such a business move appears to be the case with a recent Canon patent, which details the use of variable lens elements in combination with traditional glass elements. Read more
A new Apple patent filing describes how a single artificial muscle structure is used to replace traditional motors to control focus and aperture in a camera module.
Apple has filed a patent for using a camera OIS and software stitching to create high-resolution images.
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
Apple patents a 3D-display where users can interact with a projection image using gestures.
Earlier this week, Japanese patent blog Egami reported that Olympus has patented a technology that would allow the photographer to selectively adjust exposure of different scene areas during an exposure. This might allow for a more balanced exposure of scenes where cameras might normally struggle. Click through for an explanation of what we think the patent might mean for photographers.
The Tokyo District Court has ruled in favor of Nikon in a patent infringement case brought against Sigma. The lawsuit, filed in 2011 and settled last month alleged that six of Sigma's interchangeable lenses infringed on certain Nikon patents relating to VR (vibration reduction) technology.

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.

A patent filed by Apple in 2011 and discovered this week by appleinsider.com seems to hint at a 'social camera flash' system, allowing multiple iOS devices to be connected and used as secondary strobes for impromptu flash setups. The patent is filed as an 'illumination system' and describes 'initiating a master-slave relationship between the image capture device and at least one secondary device'. Click through for more details.
Nikon has filed a patent covering the idea of a password-based security system for lenses. The patent lists the high value of lenses as a reason for the innovation - the camera would refuse to shoot with a lens unless the correct password was entered. This is an attempt by the the company to prevent resale of stolen gear. (via Nikon Rumors)
Sensor maker Aptina has announced it has signed a patent cross-license agreement with Sony, that provides each company with access to the other’s patent portfolio. This agreement gives two prominent sensor makers access to some of each other's technologies for future development of cameras and other imaging products.
Move is the latest instance of Microsoft pursuing makers of Android devices.
A patent filed by Nikon in Japan appears to revive the long-held dream of adding a digital sensor to an existing film SLR. The Japanese Engineering Accomplishment blog found the recently published patent that shows a mechanism for mounting and adjusting the position of a digital sensor on a rear door that could be used to replace the conventional film door. However, the patent only covers the mounting of the sensor relative to the film guides - it doesn't address any of the hurdles that have stood in the way of anyone realizing this long-discussed idea.
