Canon Patent For Basic IBIS (In Body Image Stabilisation) Used To Correct Lens Eccentricity

Canon

What a neat coincidence. After a rumor about Canon featuring IBIS in future EOS R cameras, we can report a Canon patent application for a basic IBIS system spotted by Hi Lows Note.

The literature in patent application 2018-194766 seems to describe a basic IBIS system used to correct lens eccentricity. The image sensor can tilt in order to correct the lens eccentricity.

Machine translated excerpt:

[…] the optical instrument concerning the present invention, and its system, A camera device provided with the control means which carries out the tilt of the image sensor to an optic axis, It consists of a lens device provided with the detection means which detects the parameter to which the image formation performance of a lens is changed, The image sensor according to a parameter falls from the aforementioned lens device, information is transmited to the aforementioned camera device, and it is characterized by comprising the optical instrument which consists of the camera device in which the thing [ falling and carrying out the tilt of the image sensor to an optic axis based on information ] is possible, and its system.

As usual I’m glad for any help interpreting patent literature.

Sigma Patent For 12mm f/2.8 Lens For Full Frame Cameras

Sigma Patent

Is this the next super cool Sigma lens?

Hi Lows Note spotted a patent application (2018-189733) by Sigma for a 12mm f/2.8 lens for full frame cameras.

  • Focal length: 12.42 mm
  • F number: 2.93
  • Angle of view: 120.49
  • Image height: 21.63 mm
  • Lens length: 169.4 mm

Apparently the lens has some sort of distortion correction built in:

The present invention relates to the wide angle lens system in which the back focus used for a digital camera, a video camera, a film-based camera, etc. corrected several aberrations, such as a distortion aberration […]

Canon Working on RF 25-300mm F/3.5-5.6 For Canon EOS R, Patent Suggests

Canon

Hi Lows Note spotted a Canon patent application (2018-180203) for a RF 25-300mm F/3.5-5.6 lens for the Canon EOS R system. The patent literature describes a compact lens. Doesn’t look like a L-grade lens.

  • Zoom ratio: 11.68
  • Focal length: 25.20 – 294.41 mm
  • F number: 3.50 – 5.60
  • Angle of view: 36.72 – 4.20
  • Image height: 18.80 – 21.61 mm
  • Lens length: 374.08 mm
  • Back focus: 21.75 mm

Here Is A Canon Patent For In Body Image Stabilisation (IBIS)

Canon Patent

Japanese site Hi Lows Note spotted the patent of the year.

Canon patent application in Japan 2018-165756 describes an IBIS (In Body Image Stabilisation) system.

The lack of IBIS was one of the criticism Canon had to face after the launch of the Canon EOS R. There have been various statements by Canon execs about how much better image stabilisation in lens is working. However, no one ever excluded the possibility Canon might feature IBIS on future cameras. At least now we know there is a Canon patent application for it. Interesting note: the picture on top is depicting a DSLR and not a mirrorless camera.

Machine translated excerpt from the patent literature:

The imaging device of the present invention is provided with an image sensor, the frame which supports the aforementioned image sensor, and the driving member which moves the aforementioned frame in the direction parallel to the imaging surface of the aforementioned image sensor, and the aforementioned vibrating member, It has a vibration portion which vibration occurs, it sees from the direction which intersects perpendicularly to the imaging surface of the aforementioned image sensor, and the vibration portion of at least one driving member overlaps the center of the imaging surface of the aforementioned image sensor.

What do you think, is Canon considering to sport IBIS on future cameras?

Canon Patent Application for 18-55mm Lens With Variable Field Curvature

Canon Patent

Japanese blog Hi Lows Note spotted another interesting patent (2018-159876).

The patent literature describes a 18-55mm lens with variable field curvature and spherical aberrations reduction.

This appears to be a lens with a design suited for an APS-C mirrorless camera. May this come to the EOS M system one day?

  • Zoom ratio: 2.88
  • Focal length: 18.58 – 53.49 mm
  • F number: 3.56 – 5.87
  • Angle of view: 36.32 – 14.32
  • Image height: 13.66 mm
  • Lens length: 126.24 mm
  • Back focus: 11.55 mm

There is a lot of buzz around patents. Mostly for nothing. Patents are foremost a way companies have to secure their R&D efforts (research and development).

More Canon patent applications are listed here. Some particularly interesting patent applications we think might get into production in the next years are these:

Canon Patent Application for Long Eye Relief Optics in EVF

Canon Patent

Canon patent application 2018-124349 discusses optics for long eye relief (Wikipedia) in an Electronic View Finder (EVF). This is particularly useful for people wearing glasses. Otherwise they would struggle to see the whole image in the EVF. This patent application might actually go into production sooner or later.
