We are getting closer to the big Nikon Full Frame camera unveiling. but so far we know zero about the possible specs and tech. A hint might come from two brand new patents published this week in Japan. Nikoneye.com spotted them and they both describe a new autofocus system which seems to pretty much work like the “dual pixel autofocus” from Canon. But what’s added is also a time of flight measurement which measures the exact distance to the object. This is a tech first introduced by Sony.
The google translated patent says this:
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
