Canon Patent: On Camera Display Of Tilt-shift Information

Canon

Here is a new Canon patent, and it is another one referring to tilt-shift lenses.

Canon patent application 2023160385 (japan, published 11/2/2023) discusses methods and technology to display tilt-shift lens information on the camera display.

From the patent literature:

  • An object of the present invention is to provide a lens device that makes it possible to check the amount of tilting on a display screen provided in an imaging device.
  • BACKGROUND ART
    Conventionally, interchangeable lens cameras have been known that adjust the amount of tilt, such as the amount of shift and tilt amount, with respect to the imaging surface of the lens in order to perform tilted imaging. Patent Document 1 discloses a configuration in which the depth of field based on the amount of tilt is displayed on a screen provided in a camera.
  • An object of the present invention is to provide a lens device that makes it possible to check the amount of fanning on a display screen provided in an imaging device.
  • Means for Solving the Problems
    A lens device according to one aspect of the present invention is a lens device that can be attached to an imaging device, and includes at least one optical member that is moved to perform tilted imaging. It is characterized by having an imaging optical system and a transmitter that transmits information regarding the movable range of at least one optical member to the imaging device.
  • Effects of the Invention
    According to the present invention, it is possible to provide a lens device that allows the amount of tilting to be confirmed on a display screen provided in an imaging device.
  • The zoom lens 102 is movable along the optical axis of the imaging optical system, which is indicated by a broken line in the figure. When the user operates a zoom operation ring connected to a zoom mechanism (not shown), the zoom lens 102 moves along the optical axis. Thereby, zooming is performed in which the focal length of the photographing optical system is changed by moving the zoom lens 102. The zoom lens position detection unit 106 detects the position of the zoom lens 102 using a position detection sensor such as a variable resistor, and outputs position data to the lens microcomputer 111. The output position data is used by the lens microcomputer 111 to control zoom tracking operations and the like.
  • The aperture unit 103 includes sensors such as aperture blades and a Hall element. The state of the aperture blades is detected by the aforementioned sensor and output to the lens microcomputer 111. The aperture control unit 107 drives actuators such as a stepping motor and a voice coil motor in accordance with commands from the lens microcomputer 111. This allows the aperture unit 103 to adjust the amount of light.
  • The image blur correction lens 104 reduces image blur caused by hand shake and the like by moving in a direction perpendicular to the optical axis of the imaging optical system. The image shake correction lens control unit 108 drives the shake prevention actuator in response to a shake detected by a shake sensor (not shown) such as a vibration gyro based on a command from the lens microcomputer 111. As a result, image stabilization processing for controlling the shift operation of the image shake correction lens 104 is performed.
  • The focus lens 105 is movable along the optical axis. Position data of the focus lens 105 detected using a position detection sensor such as a photo interrupter is output to the lens microcomputer 111. The focus lens control unit 109 adjusts the focus by driving an actuator such as a stepping motor and moving the focus lens 105 based on a command from the lens microcomputer 111. Further, the focus lens 105 corrects image plane fluctuations caused by zooming by the zoom lens 102.
  • The revolving drive unit (rotating member) 114 is configured to be rotatable around the optical axis of the imaging optical system, and rotates at least a portion of the imaging optical system around the optical axis by rotating. The revolving control unit 117 moves the revolving drive unit 114 according to a command from the lens microcomputer 111. The position of the revolving drive unit 114 may be detected by a position detection unit (not shown). By executing a revolving drive that moves the revolving drive unit 114, the moving directions of the tilt lens 112 and the shift lens 113 can be controlled.

Canon Patent: Three Camera System For Smartphones

Canon Patent

A Canon patent related to a camera system for smartphones is a rather unusual patent for Canon. I let it to your educated speculations what if means. Do not be surprised if suddenly everyone starts spreading rumors about Canon making a smartphone.

Canon patent application 2023160089 (Japan, published 11/2/2023) discusses technology and methods for a camera system for devices like smartphones, that allows to seamlessly zoom between cameras in multiple shooting modes.

From the patent literature:

  • When capturing images in parallel in a plurality of imaging modes, the angle of view can be seamlessly switched from wide-angle to telephoto without interrupting the imaging.
  • BACKGROUND ART
    Conventionally, a photographing method has been well known in which a subject is simultaneously recorded using both an imaging section for photographing a still image and an imaging section for photographing a moving image, which are included in an imaging device. Furthermore, in recent years, imaging devices such as smartphones are equipped with a plurality of imaging units having different focal lengths, and each imaging unit can simultaneously record a subject. Furthermore, when switching the angle of view, the smartphone uses an imaging unit with the desired focal length. Patent Document 1 discloses a technique for automatically moving the zoom position of an imaging device for capturing a moving image in conjunction with a zoom operation of an imaging device for capturing a still image.
  • In Patent Document 1, each imaging device can switch to an arbitrary angle of view by performing optical zoom by driving a lens. In contrast, smartphones use multiple imaging units (lenses) with different focal lengths to switch the angle of view. For example, when capturing images in parallel in two imaging modes, still image and video, with a smartphone, in order to switch the lens for video to the lens used for still images, you must first stop using the imaging unit for still images. After that, you will be able to switch the viewing angle for video recording. Therefore, it is difficult to seamlessly adjust the angle of view from wide-angle to telephoto without interrupting imaging.
  • Accordingly, an object of the present invention is to seamlessly switch the angle of view from wide-angle to telephoto without interrupting the imaging when images are taken in parallel in a plurality of imaging modes.
  • Means for Solving the Problem
    In order to achieve the above object, an imaging device according to the present invention is an imaging
    device having a plurality of lenses having different angles of view, and which has a
    first imaging mode and a first imaging mode. 2. A reception means that receives a switching operation to switch the lens used for imaging when images are captured in parallel in two imaging modes, and in response to receiving the switching operation of the lens used for imaging, a control unit configured to control switching of lenses used for imaging, the control unit controlling the first imaging mode and the second imaging mode so that different lenses are used in the first imaging mode and the second imaging mode. The present
    invention is characterized in that the lens used in the first imaging mode and the second imaging mode is controlled to be switched .
  • According to the present invention, when images are taken in parallel in a plurality of imaging modes, the angle of view can be seamlessly switched from wide-angle to telephoto without interrupting the imaging.

Is Canon about to license this to smartphone makers?

Canon Researching A Retro Designed Camera Was Just BS (maybe)

Canon

As most of us thought, the rumor that Canon was actively conducting market research to see how customers would react to a retro camera, was, well, barely more than crap.

asobinet.com got intel from a source stating that it was nothing more than “communication with fans”. The original message (see image on top) on Weibo seems to have been:

If you could recreate any old camera, which one would you like to recreate? We look forward to your participation. A limited gift bag will be given away through a lottery.

Market research or just “communication with fans”? But there is a “but”. At the end of asobinet’s post there is this:

After the rumors started circulating, it seems that the company has started discussing the possibility. I don’t know, maybe that’s a good thing. “Everything depends on official information,” a friend said after the meeting.

So, how to interpret this? After someone made the rumor circulating, Canon decided to give it a try?

Share your thoughts if you fancy.

It Seems Canon Is Researching If A Retro Camera Would Make Any Sense

Nikon Z Fc

Is Canon doing a market research to see if a retro design camera would be a good idea? It looks like.

It’s not the first time that a Canon camera with retro design comes up. Something like the Nikon Z f or Nikon Z fc, just to be clear. Indeed, a few months ago, there was a sort of hint in an interview with a Canon exec.

Canon has a lot of bodies that go down in history, do you have any plans or ideas to release a retro camera? 

In conclusion, I can’t say yes or no, but you are right that some consumers prefer some of the best-selling models in the past, their design and appearance.

Also, you can see that we have listened to the voices and requests of our customers and made improvements to our EOS body, whether it be appearance or operability. It is very important to me that there is a consumer base that wants a retro body, but unfortunately I have no more information to share.

Yeah, neither yes nor no. However, according to some posts on Weibo, Canon might be actively conducting market research in this direction. And that’s all. So, just a rumor for now.

Stay tuned.
