Nikon Patents a Ring Flash for Compact Cameras that Uses the Built-In Flash

We’ve seen ring flash units that redirect light from a DSLR’s pop-up camera and a hot shoe-mounted flash, but never from a compact camera’s built-in flash. Based on a patent filing published earlier this month and uncovered by Egami, that’s what Nikon appears to be in the process of building.

Canon Patent Details 18-45mm Kit Lens for Mirrorless Camera

Looks like Canon has some serious plans to jump into the mirrorless camera market. The company’s G1X camera announced last month has a sensor large enough to compete with existing mirrorless cameras, but lacks an interchangeable lens system. A new patent filed by the company, however, reveals a new 18-45mm f/3.5-5.6 kit lens for an APS-C mirrorless camera. It was filed back in 2010, so it seems that the company has been working on a mirrorless camera for quite some time now.

Nikon Working on a Hybrid Viewfinder for Future DSLRs

Nikon is developing an X100-esque hybrid viewfinder for DSLR cameras. A recently published patent filing by the company describes and shows a DSLR with a viewfinder that can switch between optical and electronic modes. The purpose appears to be for providing the photographer with an optimal view of the scene — if the scene is too bright for the photographer (e.g. the camera is pointed towards the sun), then the camera switches to an electronic view that provides the user with a view that’s more suitable for their eyes.

Unlike the X100′s viewfinder, however, there is no electronic image overlaid on the optical one when in OVF mode.

Canon DSLR Patent Shows Touchscreen and Built-In Wi-Fi

We may be close to seeing a Canon DSLR with an articulating touchscreen — and possibly even built-in Wi-Fi. A patent filing discovered by Photography Bay has more details on the touchscreen, which we reported on two years ago. A sensor above the screen prevents your nose from changing settings by detecting when your face is pressed against the camera. There are also what appear to be network and Wi-Fi icons on the screen, suggesting that Canon may soon bring Eye-Fi style data transfers to DSLRs.

P.S. Canon will reportedly be announcing a new camera tomorrow. Stay tuned.

Nikon Pro DSLR Patent Shows New Dust Reduction Feature

A Nikon patent published today details a new dust reduction feature that might make its way into future Nikon DSLRs. The basic idea is the introduction of a hole at the bottom of the camera’s mirrorbox that is designed to catch dust when the mirror swings up. Nikon claims that the feature reduces dust found on the sensor by 50% after 10,000 actuations.

Upcoming Canon EF Lenses May Include Aperture Rings

Based on a recently published patent filing, Canon appears to be working on putting aperture rings on EF-mount lenses to allow the aperture to be smoothly controlled during video recording. The patent, filed by the company back in March and published late last week, talks of a “diaphragm driving unit” and shows a third ring on the lens in addition to the zoom and focus rings.

As many of you know, Canon is planning a “historic” announcement in Hollywood on November 3rd. Many people are guessing that an EF-mount camcorder will be announced, while others are hoping for a Canon 5D Mark III that’s even more geared towards filmmakers. This new patent is further proof that Canon is indeed planning big things for the filmmaking market.

Nikon May Use Fan to Cool Down Its Mirrorless Cameras

If computers can have fans, why can’t cameras? With recent Sony cameras running into unexpected limits due to the sensor overheating, Nikon may be looking to solve the problem with a good, old-fashioned fan. A recent patent filing by Nikon shows a mirrorless camera with a computer-style fan embedded into the circuit board.

Nikon Looking Into Adding a Projector to DSLR Cameras

Having figured out how to embed a projector into the body of a compact camera with the S1000pj, Nikon is now apparently looking to do the same with DSLR cameras. A recent patent filing by Nikon in Japan describes a DSLR camera that has a projector function. The text reads,

[...] when the photographing instrument is set as projector mode, the light which supported reproduced image information is projected on the screen of the photographing instrument exterior via the eyepiece of an electronic view finder, and two or more persons can see the reproduced image simultaneously projected on a screen.

Tech blogs are reacting to the fact that the projection may be through the viewfinder, concerned that photographers would have their eyeballs accidentally burned out if the projector were to be accidentally turned on. An easy fix for that problem would be to use a proximity sensor to disable the projector mode if a face is pressed against the camera… if this technology ever graduates from being a patent and enters the real world.
