Patent Details translated

The present invention relates to a zoom lens and an optical device suitable for a digital still camera or the like.

A zoom lens is often used as a shooting lens in a shooting device (camera) such as a digital still camera or a digital video camera. As a zoom lens having a high magnification ratio, a first lens group having a positive refractive power, a second lens group having a negative refractive power, and a positive refractive power arranged in order from the object side along the optical axis. A zoom lens composed of a third lens group having a positive refractive power and a fourth lens group having a positive refractive power, and configured such that the first to fourth lens groups move along an optical axis at the time of scaling. It has been proposed (see, for example, Patent Document 1). Such a conventional zoom lens is required to have a higher magnification ratio.

Patent Details Translated

The present invention relates to an imaging apparatus.
A technique for determining exposure by referring to luminance in an AF (autofocus) area is known

The user selects the photometry mode by the photometry mode selection unit 216. The user can select the desired photometry mode by operating the photometry mode selection unit. However, in the camera control unit 201, a plurality of photometry methods are sequentially executed.

Examples of photometry modes that can be selected by the user include multi-pattern photometry and highlight-weighted photometry.
Multi-pattern metering is a mode in which metering is performed for each of a plurality of areas set on the screen, and final exposure is determined based on information such as luminance distribution, color, distance, and composition of the subject.
Highlight-weighted metering is a mode in which exposure is mainly determined so that highlights on the screen have appropriate brightness.
In general, when exposure control is performed so that a highlight portion in a screen has an appropriate brightness, exposure is darker in the highlight-weighted metering method than in multi-pattern metering.

Nikon Working to Improve Motion Blur

By admin, on January 27th, 2020

Nikon is working to improve the motion blur shots you get in your camera. The camera will collect information from an angular velocity sensor (gyro) for detecting an angular velocity and multiple exposures. Once the data is collected with the help of AI (Artificial intelligent) algorithms camera will do a performance control operation with the help of VR / IBIS to obtain maximum quality.

AI is now entering into camera systems to help photographers. And it’s a welcome step to include recent technological developments in camera systems.

The present invention captures an image of a subject formed by an optical system and outputs a signal;
An image generation unit that generates an image based on the signal, and a change in the position of the image of the subject on the image sensor based on the two images captured with a time difference corresponding to the focal length of the optical system And a motion vector calculation unit that calculates a motion vector indicating

Nikon DPAF Sensor on Work - Patent

By admin, on December 12th, 2019

From the patents it’s look Nikon is actively working their own version of DPAF sensors and sooner or later we will have new breed of Nikon sensors in upcoming Mirrorless cameras.

From patents (Translated)
To provide a focus detection device with which it is possible to detect a focus with high accuracy without being affected by color of light.SOLUTION: A focus detection device comprises: a phase difference detection unit for detecting phase difference by using a plurality of first pixels for outputting a pair of first signals corresponding to the luminous amount of a first color, a plurality of second pixels for outputting a pair of second signals corresponding to the luminous amount of a second color, and phase difference in the pair of first signals, or the pair of second signals; and a defocus amount calculation unit for calculating a defocus amount by using a first coefficient corresponding to the first color when the phase difference is detected by using the pair of first signals, and calculating a defocus amount by using a second coefficient corresponding to the second color when the phase difference is detected by using the pair of second signals.

Nikon to Add Dedicated Lens Menus In DSLRs and Mirrorless Cameras

By admin, on November 30th, 2019

Nikon is working to improve lens based user interlace in camera with a dedicated Lens Menus options which will include all the lens related settings / options in a single menu page.

Patent Details

The present invention relates to an imaging device.

In interchangeable cameras such as single-lens reflex digital cameras, it is necessary to make settings related to the attached lens on the camera side, but depending on the type of interchangeable lens (for example, whether or not it has an aperture ring) The setting items are different, so when changing to a different type of lens, the setting must be changed each time. Patent Document 1 describes a camera in which a lens can be replaced, in which the presence or absence of a diaphragm ring mounted on an interchangeable lens is determined by the camera, and the operation menu of the camera body is optimized according to the presence or absence of the diaphragm ring. .

The lens menu will guide you the type of lens you are using and if you are using a FX lens in DX format camera you will get all the details how much Magnification ratio you will be getting while using FX lens in DX Camera. And if you are mounting FX Lens in DX camera then you will get all details about crop factor and resolution loss.

This patent also indicate Nikon may minimize the presence of physicals button on the lens surface. Having less function button on lens will reduce the cost and will also improve the durability of the lens.

We will update you soon as we get any new information.
