Latest patents from Canon, Cosina, Panasonic and Samsung

Canon's patent 2011-145518 for a 16-35mm f/2.8 lens:

  • Publication date: Jule 28th, 2011
  • Patent filing date: January 15th, 2010
  • Focal length: 16.48 - 33.95 mm
  • Aperture: 2.91
  • Half angle of view: 52.70 - 32.51 °
  • 4 aspherical elements
  • Zoom ratio: 2.06

Cosina filed a patent 2010-197640 for a lens adapter that can detect the rotation of the focus ring of a manual focus lens and transfer it to the camera body as an electronic signal:

"Problem to be solved: to easily and surely perform focusing, even when an old type interchangeable lens known as a famous interchangeable lens is attached to the latest digital camera body."

Panasonic filed a patent 2011-142592 for reducing the rolling shutter distortion.

The last patent for today is from Samsung and is about creating DSLR-like bokeh for compact cameras:

"While the primary lens is capturing the full-resolution image, a secondary lens and sensor captures another image with the sole purpose of evaluating the relative distances of areas in the image.  (In some configurations, the camera may actually be a 3D camera, while in other configurations, it may truly be a secondary lens and sensor.) Then, the camera merges the data with the primary image to create a depth map and applies a graduated blur based on this depth map."

    Hello GH3.

    I find the Samsung patent absolutely fascinating.

    • Harryson

      Agree. If this concept really develops into a mature product, it’ll be a very big step in camera development and in-camera image processing. Quite smart thinking here from Samsung.

      • Well you can see how good it can get, even before it’s released:

        Take two shots of the same thing side by side, import the two images to photoshop. Get the difference or something between the two and apply blur proportional to the content on the difference map.

    Couldn’t this artificial low DOF effect be produced by using AF sensors and computers inside the camera?
    Why the second lens…?

      A second lens looks like a very elegant solution, it allows triangulation (just like a Leica M). It should work better for shorter and normal focal lengths than for big teles, though.

      Using AF information from contrast detection would still be limited by the huge depth of field of compact cameras.

      • Camaman

        But or DSLRs that have small DOF AF sensors could do just fine, NO?
        They would work even better if they were spread better across the screen.
        Also Nikon has an advantage, seeing how their bodies have way more AF points. They can offer more resolution in the depth perception to the software in the camera.

    Talking of Canon, they have slashed their prices in Australia because buyer are fiding it cheaper to buy Canon equipment from overseas online companies…
    “Canon who is struggling from consumers moving online to buy their products from overseas websites, has slashed the price of their cameras in Australia bringing them into line with overseas online prices. They are also set to spend up to $15M trying to convince consumers to buy a Canon product.
    After slashing the Australian prices of some of its products, Canon’s pricing has fallen in line, or at times even cheaper than those offered in the US market.
    The Company, who is under pressure from the likes of Nikon, who recently rolled out a major marketing campaign for their new digital SLR camera’s as well as Olympus and Panasonic who recently launch new micro two thirds camera’s has also witnessed a significant fall off in demand for Canon camera’s in Australia during the past six months.
    Earlier today the Company slashed the price of more 95 camera skews. They have also announced a brand new marketing campaign that will see them go up against a new $2.5M campaign being rolled out by Olympus and the expansion the Nikon campaign which Nikon marketing director Nick Segger said had “been very successful in Australia”.”
