Canon Patent: Haptic Feedback On Camera Operations

Canon Patent
View Post

A new Canon patent application: haptic feedback, i.e. vibration, for feedbacks when “beeps” should be avoided.

Canon patent application 2023-147064A (Japan, published 10/12/2023) discusses technology and methods to implement a haptic feedback in a camera body.

From the patent literature:

  • The present invention provides an electronic device that can provide appropriate notification depending on a user’s holding state of the electronic device or a setting state of the electronic device.
  • BACKGROUND ART: Hitherto, there has been known an electronic device having a function of causing the vibrating device to generate vibration at a predetermined timing and notifying the user. By using vibration (tactile sensation), notifications can be made without relying on sight or hearing, which is useful in that it does not easily affect the user’s operation of electronic devices. Patent Document 1 discloses a configuration in which a plurality of piezoelectric members are arranged in a grip section or a display section of a camera, and the piezoelectric member with the largest contact area with the user’s hand is deformed to notify the user.
  • However, in the configuration disclosed in Patent Document 1, since the piezoelectric member that has a large contact area with the user’s hand is deformed, depending on the state or setting of the camera, the Users may not be able to properly recognize notifications.
  • SUMMARY OF THE INVENTION: Therefore, an object of the present invention is to provide an electronic device that can provide appropriate notification depending on the state in which the electronic device is held by the user or the setting state of the electronic device.

It seems the described system recognises how the user is holding the camera body (which hand?) and then activates the right motors, which are the items 100 and 100b in the image on top. If I got it right, the described technology gets the hand position through pressure measurements on the grip. Not sure if this patent will go into production any time soon.

Going Wide: Canon Introduces The  RF10-20mm F4 L IS STM to Its Lens Lineup

MELVILLE, NY, October 11, 2023 – Today, Canon U.S.A., Inc., a leader in digital imaging solutions, announced the launch of the RF10-20mm F4 L IS STM lens, a full-frame ultra wide-angle lens that can help the work of a professional photographer or serious enthusiast stand out from the crowd.

Opening the door to supreme full-frame visual possibilities, the RF10-20mm F4 L IS STM lens continues Canon’s respected reputation for optical excellence associated with L-series lenses. This new addition enhances optical performance with a modern mirrorless lens design that is fully equipped with key features, including:

  • New Image Stabilization (IS) technology, to help minimize wide-angle “fluttering” at outer areas of frame
  • Impressively compact size and light weight (1.25lbs/570g) at half the weight of EF series 11-24mm f/4 L lens
  • Super quiet Canon STM focus drive motor, which is ideal for video and marking the first time this technology appears in a Canon L-series lens

Speaking directly to the professional video and stills visual storyteller, the RF10-20mm F4 L IS STM features a built-in lens hood and lens function button on the barrel for customizing functions such as AF settings, Pre-Recording, Zebras and more. For landscapes, cityscapes, architectural, real estate and weddings, the RF10-20mm F4 L IS STM lens is a widely important lens for any professional to have at the ready.

Canon Patent: Wide-angle Fixed Lens For 1″ Imaging Sensor (PowerShot?)

A new Canon patent for a wide-angle single focus lens for a camera with an 1 inch imaging sensor. A new PowerShot camera?

Canon patent application 2023-140823 (Japan, published 10/5/2023) discusses optical formulas for a 28mm-35mm equivalent wide angle lens for a camera with an 1 inch imaging sensor.

From the patent literature:

Optical system and imaging device having the same

The present invention provides an optical system that is compact and has high optical performance, and an imaging device that includes the same.

BACKGROUND OF THE INVENTION

In recent years, with the miniaturization and increase in the number of pixels of image pickup devices, optical systems used in image pickup devices are required to be small and have high optical performance.

Problems to be Solved by the Invention

The optical system described in Patent Document 1 uses a telephoto type power arrangement to reduce the overall length, and uses a plurality of aspheric lenses to reduce distortion and image plane. Curvature is being corrected. However, in the optical system described in Patent Document 1, the Petzval sum of the entire system is large and the incident angle of the off-axis light beam is also large, so when trying to apply it to an imaging device with a large imaging element, it is difficult to correct field curvature or reduce the amount of peripheral light. Decrease is an issue.

Example 1

  • Focal length: 13.82
  • F value: 2.88
  • Half angle of view: 29.72
  • Image height: 7.89
  • Total length: 16.32
  • Back focus: 4.83

Example 2

  • Focal length: 17.20
  • F value: 2.06
  • Half angle of view: 24.65
  • Image height: 7.89
  • Total length: 21.52
  • Back focus: 5.22

Example 3

  • Focal length: 12.64
  • F value: 2.91
  • Half angle of view: 31.97
  • Image height: 7.89
  • Total length: 15.87
  • Back focus: 4.19

Example 4

  • Focal length: 10.39
  • F value: 2.55
  • Half angle of view: 37.20
  • Image height: 7.89
  • Total length: 15.65
  • Back focus: 4.54
