Nikon Patent - Lens with Touch and Pressure Sensor

The New Camera Exclusive – Nikon is working on completely new technology. We have spotted a Nikon Lens with Touch and Pressure Sensor.  So, you can now zoom your lens with the touch of your hand. Future DSLR/ Mirrorless lenses may carry advance sensor controls.

 

Nikon lens with touch sensors

Description: (Translated Version) To allow a lens position when a hand is released from a lens barrel to be held.SOLUTION: A lens barrel 10 of a digital camera 1 comprises: a barrel that houses an imaging optical system 20; and touch sensors 12, 14 and 16 that are provided in a periphery of the barrel, and detect a state where an operator contacts with respect to the barrel or a contactless state. When the touch sensors 12, 14 and 16 detect the contact, a CPU 32 allows a zoom lens 21, a focus lens 23 and an aperture stop 25 which correspond to each sensor to move or open/close, and when the touch sensors 12, 14 and 16 do not detect the contact, the CPU 32 locks the movement of the zoom lens 21 and the focus lens 23 or the opening/closing of the aperture stop 25 via a locking section 34.

New camera tocuh sensor

(Translated version ) In a digital camera equipped with a retractable lens, when a pressure sensor is attached to the grip portion of the digital camera and it is detected by the pressure sensor that the camera is in a non-gripping state from the state of gripping the camera, the camera is falling (For example, refer to Japanese Unexamined Patent Application, First Publication No. Hei 11-94926). In this technique, the lens is collapsed to prevent breakage.

[0009] The zoom ring 11 is an operation ring that manually moves the zoom lens in its optical axis direction. The zoom ring touch sensor 12 is a sensor that detects contact of an object by detecting changes in electrostatic capacitance and electric resistance. The zoom ring touch sensor 12 is provided on the zoom ring 11 and can detect contact with the zoom ring 11. It should be noted that the zoom ring touch sensor 12 may be provided in the vicinity of the zoom ring 11 with a high possibility of being touched when operating the zoom ring 11.

[0010] The focus ring 13 is an operation ring for manually moving the focus lens in its optical axis direction. Similarly to the zoom ring touch sensor 12, the focus ring touch sensor 14 is a sensor for detecting contact of an object. The focus ring touch sensor 14 is provided on the focus ring 13 and can detect contact with the focus ring 13. It should be noted that the focus ring touch sensor 14 may be provided in the vicinity of the focus ring 13 with a high possibility of being touched when operating the focus ring 13.

Nikon Projector Compact Camera Patent

Nikon projector cam patent

Is Nikon projector compact camera really dead ? Nikon discontinued the Nikon Projector compact camera line more than a year ago and the last model of projector compact was Nikon Coolpix S1100pj [Amazon | B&H]

We have received a projector camera patent document that shows a bit different design the existing Projector compact cameras.

Not only design of the patent is different the date of the patent is also new. Take a look at the patent details

Nikon Patent One More PDAF Sensor

Nikon patent Hybrid sensor patent

A new patent surfaced over the web that shows Nikon is working on Phase Detect Autofocus Sensor. However we have published several patent in past that shows Nikon is actively working to bring Phase AF sensor inside DSLRs and Mirrorless.

Patent Details

Japanese Unexamined Patent
Application Publication No. 2017-216578 (P2017-216578A)
[Publication date] December 7, Heisei 20 (2017.12.7)
Patent application title: Imaging device and electronic camera

The patent isn’t new and we have also published Nikon AF adapter for Mirrorless cameras and also a New Hybrid sensor, take a look.

Also see one more Hybrid AF sensor patent Published on Aug 2018.

Also see Nikon working on Multilayer Hybrid AF sensor patent.

I personally do believe that Nikon will bring Hybrid AF sensor to its DSLR very soon. Can you guess the name of Nikon upcoming model that will carry a Hybrid AF sensor inside it. Do share your thoughts in the comment box below

EXCLUSIVE - Nikon Patent AF Adapter to use DSLR Lenses on Mirrorless

Nikon Patent

Nikon done a bit complex patent, in the image above you can see that Nikon is working on compact Mirrorless system with Hybrid sensor. The figure shows the camera adopt a Hybrid AF adapter built in Pellicle (Transparent) Mirror and a dedicate phase AF module. With the use of Hybrid AF adapter Mirrorless system camera will get converted into DSLR system.

The AF adapter will compensate the flange distance and will allow you to use traditional DSLR lenses in your APS-C or FF Mirrorless camera.

Nikon Hybrid Sensor for Mirrorless Camera

The image taken from Nikon patent document that shows a Hybrid PDAF sensor. We do expect that the upcoming cameras (including DSLRs and Mirrorless) will feature Hybrid sensor for enhanced AF support.

Nikon Patent - 35mm FF Lens with Curve Sensor

A wired lens patent from Nikon surfaced over the web, we are saying wired since the lens us made for curve sensor. And if you look at the patent image the camera doesn’t have any mirror inside. So, the patent clearly shows us future Nikon Mirrorless camera with a curve sensor.

The patent doesn’t specify that camera is a Compact camera or a Mirrorless camera. Few weeks ago we have told you that Nikon is working on High-End Mirrorless camera and just after that Nikon also officially confirmed the same. It is also possible that Nikon may be working on a Sony RX1 series competitor ? since the lens attached with the camera is a 35mm F2 fixed lens.

Earlier we have received information that Nikon will going to expand the Nikon 1 series camera.

Nikon Patent - BSI CMOS Sensor with Dual Pixel AF

Fig-1-Nikon-patnet

Before we begin I must admit it it’s very hard to understand a patent literature,  but after analyzing the entire document we concluded that Nikon working on a BSI CMOS AF Sensor. The sensor won’t have dead Phase AF pixels as the other Hybrid sensor have, instead of that it working principle looks same as Canon’s Dual-pixel CMOS AF sensor.

Nikon Dual Pixel AF Sensor ?

Till now only Canon was only company who was using dual pixel CMOS AF Technology. But when we have seen the new Nikon latest patent where two sub pixels involved in acquiring AF, that clearly indicates Canon isn’t alone and Nikon will soon bring a new class of Hybrid Sensors for it’s DSLRs and Mirrorless cameras in near future.

Patent Details:

BACKSIDE ILLUMINATION IMAGE
SENSOR AND IMAGE-CAPTURING DEVICE
Applicant: NIKON CORPORATION, Tokyo (JP)
Appl. No.: 15/260,994
Filed Date: Sep. 9, 2016
Pub. Date: Dec. 29, 2016

Nikon-new-sensor-tech

But now after looking at the patent we have got its look like Nikon is also interested in working on the same dual pixel CMOS sensor Technology.

Details from the patent document

A backside illumination image sensor that includes a semiconductor substrate with a plurality of photoelectric conversion elements and a read circuit formed on a front surface side of the semiconductor substrate, and captures an image by outputting, via the read circuit, electrical signals generated as incident light having reached a back surface side of the semiconductor substrate is received at the photoelectric conversion elements includes: a light shielding film formed on a side where incident light enters the photoelectric conversion elements, with an opening formed therein in correspondence to each photoelectric conversion element; and an on-chip lens formed at a position set apart from the light shielding film by a predetermined distance in correspondence to each photoelectric conversion element. The light shielding film and an exit pupil plane of the image forming optical system achieve a conjugate relation to each other with regard to the on-chip lens.

Details from the patent document clearly indicates that Nikon is working on a BSI CMOS sensor that will have two sub pixels that will do AF by calculating the amount of lens drive Between the two autofocus point.

The image above of the patent you will get a clear indication that Nikon will do the same as Canon has done in many of its full frame and aps-c DPAF sensor camera. we are the first website to show you the details of the patent till now it is also possible that even Canon doesn’t know about this technology that Nikon working on.
