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

Canon Patent

There might be no more doubt that Canon is actively working on IBIS (In Body Image Stabilisation). Here is another Canon patent application.

Canon patent application 2019-152785 describes an IBIS unit and its working. An excerpt from the paten literature:

Problems of the stage device as the blur correction mechanism of such an image pickup device include high efficiency in driving force generation and linearity improvement of a magnetic circuit for position detection. In response to this problem, Patent Document 2 discloses a configuration in which three magnets are arranged for each driving force generation unit to form a magnetic circuit using the concept of the Halbach array (hereinafter referred to as “Halbach magnetic circuit”).

it is possible to achieve high efficiency in generating driving force and to improve the linearity of the magnetic circuit for position detection

Some rumor outlets are presenting this patent application as the patent describing “the IBIS” Canon is going to feature on future cameras. We’d be a bit more cautious with such claims. There is nothing to proof it is “the IBIS”. More likely, it’s just one more IBIS patent in a long row.

We have no doubt IBIS is indeed coming to future Canon cameras. We would just be a bit more prudent and avoid saying it will be on board on Canon’s next EOS R model (which most likely it will not). Not on the next one, but maybe on the camera coming after.

Canon Is Working Hard On IBIS, Yet Another Patent Suggests

Ibis

It seems to be a no brainer that Canon will soon implement IBIS (In Body Image Stabilisation) on their cameras. Another Canon patent shows the company is working hard on this technology.

Canon patent application 2019-0260938 (USA) discusses how to make IBIS and lens IS work together. It’s not the first Canon patent about IBIS/lens IS we spotted, another one is this one. All IBIS related Canon patent applications are listed here.

From the patent abstract:

An image capturing apparatus comprises: a shake detection sensor which detects shaking; a calculation circuit which calculates a first shake correction amount based on a shake signal output from the shake detection sensor; a transmitting circuit which transmits the first shake correction amount to a lens apparatus that comprises first image stabilization apparatus for correcting shaking by moving an optical system; and a lens characteristics correction circuit which performs correction regarding lens characteristics in an image signal obtained by image-capturing in a state in which the first image stabilization apparatus has corrected shaking, based on the first shake correction amount, wherein the lens characteristics correction circuit performs the correction regarding lens characteristics based on the first shake correction amount at a time prior to the image-capturing time by a predetermined time

According to the patent literature, it can be done in the following way:

[0008] The present invention has been made in consideration of the aforementioned problems, and realizes a technique in which, when correction regarding lens characteristics is performed in a camera main body while using a camera shake correction apparatus on an interchangeable lens side, at least the influence of delay in communication between the interchangeable lens and the camera main body is reduced. [0009] In order to solve the aforementioned problems, one aspect of the present invention provides an image capturing apparatus, comprising: a shake detection sensor which detects shaking; a calculation circuit which calculates a first shake correction amount based on a shake signal output from the shake detection sensor; a transmitting circuit which transmits the first shake correction amount to a lens apparatus that comprises first image stabilization apparatus for correcting shaking by moving an optical system; and a lens characteristics correction circuit which performs correction regarding lens characteristics in an image signal obtained by image-capturing in a state in which the first image stabilization apparatus has corrected shaking, based on the first shake correction amount, wherein the lens characteristics correction circuit performs the correction regarding lens characteristics based on the first shake correction amount at a time prior to the image-capturing time by a predetermined time. [0010] Another aspect of the present invention provides, a control method of an image capturing apparatus comprising: detecting shaking using a shake detection sensor; calculating a first shake correction amount based on a shake signal output from the shake detection sensor; transmitting the first shake correction amount to a lens apparatus that comprises a first image stabilization apparatus that corrects shaking by moving an optical system; and performing correction regarding lens characteristics in an image signal obtained by image-capturing in a state in which the first image stabilization apparatus has corrected shaking based on the first shake correction amount, based on the first shake correction amount at a time prior to the image-capturing time by a predetermined time. [0011] Still another aspect of the present invention provides, a non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method of an image capturing apparatus, the method comprising: detecting shaking using a shake detection sensor; calculating a first shake correction amount based on a shake signal output from the shake detection sensor; transmitting the first shake correction amount to a lens apparatus that comprises a first image stabilization apparatus that corrects shaking by moving an optical system; and performing correction regarding lens characteristics in an image signal obtained by image-capturing in a state in which the first image stabilization apparatus has corrected shaking based on the first shake correction amount, based on the first shake correction amount at a time prior to the image-capturing time by a predetermined time. [0012] According to the present invention, when correction regarding lens characteristics is performed in a camera main body while using a camera shake correction apparatus on an interchangeable lens side, at least the influence of delay in communication between the interchangeable lens and the camera main body can be reduced.

Canon EOS 90D To Be Announced In August 2019?

Canon Eos 80d

After the rumor suggesting Canon will feature IBIS (In Body Image Stabilisation) on the Canon EOS 90D, now we have a rumor about the announcement date.

The August announcement was already rumored. Some supposed specifications for the EOS 90D have also leaked. The news are that the EOS 90D (all rumors) announcement could go along with the announcement of other new Canon gear. As we reported, the EOS 90D is most likely the replacement for both the EOS 80D and EOS 7D Mark II.

According to the source, in August Canon might also announce the replacement for the EOS M5/M6.

Finally, some new lenses are also possible. Since Canon stated there would be no new EF lenses in 2019, you can speculate they will be either EF-M lenses or the already announced yet not released new RF lenses. These are the “holy f/2.8 trinity”: RF 70-200mm f/2.8L IS, RF 24-70mm f/2.8L IS and RF 15-35mm f/2.8L IS. Then there is also the RF 85mm f/1.2L DS (DS = Defocus Smoothing“).

Stay tuned.

Canon EOS 90D To Feature IBIS (In Body Image Stabilisation)?

Eos 80d

Will the Canon EOS 90D have IBIS on board?

Perfectly on schedule after a row of IBIS related Canon patent applications, a rumor suggesting Canon might feature IBIS in future DSLRs surfaced. Indeed, there has also been a Canon patent application discussing IBIS in DSLRs.

The rumor suggests IBIS is “definitely” soon coming to “select” DSLRs”. The source suggests the upcoming Canon EOS 90D (all rumors), and later the EOS-1D X Mark III, could be the first two Canon DSLRs to have IBIS on board. There have been rumors the Nikon D6 will feature IBIS, so you can expect it on the EOS-1D X Mark III too. As we reported, the EOS 90D is most likely the replacement for both the EOS 80D and EOS 7D Mark II.

The lack of IBIS in Canon’s mirrorless and DSLR offering has always been cause for criticism from users. I guess Canon is the last Camera manufacturer without an offering featuring IBIS. However, for the time being we suggest you take this rumor with a grain of salt.

Stay tuned.

And Here Is One More Canon Patent Dealing With IBIS (In Body Image Stabilisation)

Ibis

Here is another Canon patent application (US 2019-0222763) dealing with IBIS (in Body Image Stabilisation).

As seen with another Canon patent about IBIS, here too the discussion is about how to make IBIS and lens IS work together smoothly. An algorithm is described that allows the camera to chose if use IBIS, lens IS, or both together.

Given all the recent Canon patent dealing with IBIS, you can safely assume that Canon will soon feature it on their camera bodies. Most likely first on the EOS R system, but there has also been a patent discussing IBIS on a DSLR.

So, IBIS is coming to the Canon universe. Sure thing.
