Nikon’s New Mirrorless Might Feature a Dual Pixel Sensor

A recently revealed patent appears to show that Nikon are working on their own version of Canon’s DPAF technology, to be deployed in there forthcoming range of mirrorless cameras.

It would appear from the information we have recieved, in the form of a patent, that the system works in a similar fashion to Canon’s DPAF system. The patent does describe one added feature of the Nikon system however, namely the ability to calculate the distance between the sensor and the object being focused upon.

There is known a time-of-flight (TOF) measurement method for measuring a distance to an object by receiving reflected light of light irradiated to the object (for example, Patent Reference 1). When measuring the distance to the object by such a method, it is difficult to obtain the image of the object at the same time.

It has a set part which sets up the range which detects a focusing state from the information about the exit pupil of the aforementioned imaging optical system, and the information about the aforementioned pixel for focus detection, and a transmission section which transmits the information about the aforementioned range set up by the aforementioned 

Knowing the exact distance to an object would certainly allow very fine automated control of focus so it will be interesting to see exactally how Nikon utilize this feature.

We are looking forward to the announcement of Nikon’s new range of mirrorless cameras so stay tuned for further info!
