NEW CAMERA

We have published patents before about Nikon Hybrid Sensor for DSLRs. But, from the latest patents, its look like Nikon have created their own version of Dual Pixel CMOS AF System.

Nikon dedicated AF pixel ROW inside a DSLR sensor, most importantly if they are using the same mechanism as of DPAF . Then of-course we will have sensor without Dead Hybrid AF pixels.

from patent document: example, as shown in FIG. 10, the imaging device 22, an imaging device 221 for imaging, the focus detection pixels 222a for phase difference detection, and a 222b, the focus detection pixels 222a

Patent –

Nikon Sub-Pixel AF structure

Not only that, You can clearly see Nikon DSLR display with AF segments or you can say AF groups just like we have in Canon’s. But the sub pixel arrangement is entirely different from Canon, here every pixel isn’t divided into two sub pixels. Instead of that Nikon is using two pixels for AF work each on having a sub-pixel unit.

In every pixel you can see two sub-pixel division, looks similar to dual pixel CMOS AF tech were every two sub pixels are involved in AF.

Nikon Display with dedicated AF Zones

Nikon DSLR camera Display screen will be distributed in AF Zones. Once you click the display unit AF section the AF area will be automatically zoomed [optional feature].

For sure these new sensors tech will be implemented soon in upcoming Nikon DSLRs. Camera.

Nikon Patent – Sensor Heat Management inside DSLRs

Thenewcamera exclusive: We have sorted out some of the best and Recent Nikon patent filled in the year of 2018. let’s have a look at the patent details and information. The good thing to notice here is Nikon haven’t postponed the development Nikon DSLR in favor of Mirrorless system cameras. Their R&D team working continuously to bring out new innovation in next generation of DSLRs

1. Improving DSLR lenses VR (Image Stabilization)

In a Recent patent by Nikon, you can clearly see that Nikon is working to improve the VR (image stabilization of Nikon DSLRs lenses). More details co0ming out from patent documents are below

Application Number: 2018034227 Application Date: 28.02.2018
Publication Number: 2018116288 Publication Date: 26.07.2018
Applicants: Nikon Corporation

[ Translated Patent Details ]: To provide a shake correction device that allows for reference value correction excellent in accuracy.SOLUTION: According to the present invention 100, a shake correction device 100 correcting tremors of optical members 1B and 6 comprises: an angular velocity sensor 12 that detects angular velocity of the optical members 1B and 6; a reference value computation unit 34 that computes a reference value of an output signal of the angular velocity sensor 12; an imaging element 3 that generates an image signal for each of continuous frames on the basis of input subject image light; a motion vector computation unit 41 that computes a motion vector of an image between the frames on the basis of the image signal; a reference value correction unit 42 that corrects the reference value on the basis of the motion vector; and a target position computation unit 36 that computes a target position of the optical element to be moved for causing the optical members 1B and 6 to perform a shake correction on the basis of the output signal of the angular velocity sensor 12 and the post-corrected reference value. The target position computation unit 36 is configured to, during an exposure of the imaging element 3, compute the target position on the basis of the post-corrected reference value in a pre-exposure.

2. Nikon Patent Intelligent Optical Viewfinder to Protect Photographer Eyes

To protect eyes from high-brightness subject specifically SUN, the viewfinder will now have a light-sensor to detect the amount of light passing through the viewfinder and will control the out-put whenever required to protect photographers eye. Take a look at the translated patent details below

Publication Number: 2018116291 Publication Date: 26.07.2018

[ Translates Patent Description ] The present invention relates to a camera having a function of protecting the eye from the high-brightness object. When viewed high luminance object such as the sun through the camera viewfinder, it can adversely affect the pupil. Therefore, in order to protect the eyes, and the photometry sensor the finder optical path, provided eyepiece shutter or eyepiece aperture, when the strong light exceeding the reference value the incident, light shielding or reduced by operating the eyepiece shutter or eyepiece diaphragm camera for light quantity control of such light are known

Nikon Z Series Underwater Housing and Adapter Image Spotted

We have searched a lot  int this patent about details, however it’s sometimes hard to dig out all the details from translated machine language. From the translated text it’s very clear that Nikon is working on more new type of adapters for its Mirrorless cameras at the same time it’s really bit strange to see a Camera under-water housing showcased in the patent image. May be they were trying to hide the new Nikon Mirrorless camera models  ?
