Canon patent for videocamera with compound eye-like lens and light-field technology

eg

Canon filed a patent for what appears to be a Lytro-like technology. The patent refers to a “compound eye” lens, i.e. an optic element with several lenses, each having a different focal distance. Such a device is capable of refocusing images after being taken.

This is called Light-field photography, and Wikipedia has a definition for it:

A light field camera (also known as plenoptic camera) captures information about the intensity of light in a scene, and also captures information about the direction that the light rays are traveling in space. One type of light field camera uses an array of micro-lenses placed in front of an otherwise conventional image sensor; to sense intensity, color, and directional information.

Light-field photography is part of computational photography, and again we have a good definition:

Computational photography or computational imaging refers to digital image capture and processing techniques that use digital computation instead of optical processes. Computational photography can improve the capabilities of a camera, or introduce features that were not possible at all with film based photography, or reduce the cost or reduce the size of camera elements. […] Light field cameras use novel optical elements to capture three dimensional scene information which can then be used to produce 3D images, enhanced of depth-of-field, and selective de-focusing (or “post focus”). Enhanced depth-of-field reduces the need for mechanical focusing systems

However, the patent refers to a video camera. This makes everything more interesting. I couldn’t find any reference to a sensor technology in the patent description. I wonder if this is going to feature a new sensor technology. I am not an expert in this domain, so any help is welcome.

  • Patent Publication No. 2015-122677
    • Published 2015.7.2
    • Filing date 2013.12.25
  • Canon patents
    • a plurality of lenses that focus processing is different
    • Sequentially performs the subject detection to the focal length is long order

The patent was spotted by Egami (translation).

Canon Celebrates Milestone With Production Of 110 Million Interchangeable EF Lenses

110

Canon press release:

MELVILLE N.Y., July 8, 2015 – Canon U.S.A. Inc., a leader in digital imaging solutions, today announced that its parent company, Canon Inc., will celebrate the achievement of a new lens-manufacturing milestone with the production of the Company’s 110-millionth EF-series interchangeable lens for Canon EOS cameras on June 22, 2015 -an EF 11-24mm f/4L USM ultra-wide-angle interchangeable zoom lens.

Production of interchangeable EF lenses for Canon EOS-series AF (autofocus) single-lens reflex film cameras began in 1987 at the Company’s Utsunomiya Plant. Over the years, EF lenses have garnered support from a wide range of users and production has since expanded to a total of four manufacturing bases, including Canon Inc., Taiwan; Canon Opto (Malaysia) Sdn. Bhd.; and Oita Canon Inc. in southern Japan.

EF lens production surpassed the 10-million-unit mark in 1995 and crossed the 50-million-unit threshold in 2009. In April 2014, the Company celebrated its first-in-the-world achievement of having manufactured 100 million EF lenses, and now, will set a new world record for the most interchangeable lenses produced.

Canon’s proprietary EF lenses, launched in March 1987 along with the EOS SLR camera system, have continued to evolve since their introduction, leading the industry through the incorporation of a wide range of innovative technologies, including such world’s firsts as the Ultrasonic Motor (USM), Image Stabilizer (IS) technology, a multi-layered diffractive optical (DO) element, and Subwavelength Structure Coating (SWC) anti-reflection technology.

The 110-millionth EF lens, an EF 11-24mm f/4L USM (launched in February 2015), features a minimum focal length of 11mm to achieve the world’s widest angle of view.1 Furthermore, winner of the prestigious Camera Grand Prix Japan 2015 Lens of the Year award,2 the model was recognized for its use of Canon proprietary optical technologies, making possible superb image quality while effectively correcting for aberrations that commonly occur when shooting at the ultra-wide-angle end.

The Company’s extensive EF lens-series lineup currently comprises a total of 97 models,3 including EF Cinema Lenses for digital cinematography. Canon will continue refining its imaging technologies centered on its EF lens lineup, striving to cater to the varying needs of photographers-from first-time users to advanced amateurs and professionals-while contributing to expanding the photographic and video imaging culture.

Revolutionary Canon EF lenses over the years: main features and technologies
Model name Main features and technologies Launch date
EF 300mm f/2.8L USMi World’s firstii use of a lens-based Ultrasonic Motor (USM)
USM technology delivers fast autofocusing thanks to its high torque and responsiveness. By converting ultrasonic vibrations into rotational energy, the technology makes it possible for quiet, smooth AF drive performance.
Nov. 1987
EF 75-300mm f/4-5.6 IS USMiii World’s firstii use of Image Stabilizer (IS) technology
Users can see the results of IS technology through the viewfinder. Delivering high precision and stability for exceptional image stabilization results, this technology expands the possibilities for handheld photography.
Sept. 1995
EF 400mm f/4 DO IS USMiv World’s firstii use of a diffractive optical (DO) lens element
Diffraction is an optical phenomenon in which light waves bend as they pass around the edges of an object. DO lens elements use this phenomenon to correct for a variety of aberrations by controlling the path that light travels.
Dec. 2001
EF 24mm f/1.4L II USM World’s firstv use of Subwavelength Structure Coating (SWC)
SWC technology minimizes reflections by aligning countless wedge-shaped structures more minute than the wavelength of visible light on the surface of a camera lens.
Dec. 2008
EF 100mm f/2.8L Macro IS USM World’s firstii use of Hybrid IS, which compensates for both angle camera shake and shift camera shake
Employing a newly-developed algorithm, Hybrid IS optimally adjusts for camera shake based on information gathered by two sensors located in the lens. By precisely driving the optical correction system, the technology simultaneously corrects for angle and shift camera shake.
Oct. 2009
EF 8-15mm f/4L Fisheye USM World’s firstii fisheye lens to deliver both 180-degree diagonal angle of view and 180-degree circular fisheye
The EF 8-15mm f/4L Fisheye USM lens enables the capture of images with dramatic deformations, exaggerated perspectives and extreme depths of field, making possible images that are significantly distorted, similar to what a fish might see were it to look skyward from under the water surface.
July 2011
EF 200-400mm f/4L IS USM Extender 1.4x World’s firstii super-telephoto zoom lens to employ an internal extender
Featuring a built-in 1.4x extender, the EF 200-400mm f/4L IS USM Extender 1.4x’s lens zoom range can be expanded with a simple one-touch operation even in locations where users are unable to switch lenses.
May 2013
EF 11-24mm f/4L USM World’s firstii lens offering ultra-wide-angle 11mm minimum focal length
In addition to achieving the world’s widest angle of view starting at a minimum focal length of 11mm, the EF 11-24mm f/4L USM effectively corrects for aberrations commonly associated with ultra-wide-angle lenses, delivering superior image-quality performance.
