Canon has filed a patent application for a new quad pixel autofocus sensor that would seem to replace its current Dual Pixel AF technology.
Canon News uncovered the Japanese patent application, which explains that Canon has split the pixel into four pieces and offsets the microlenses as you move further away from the centre. The application states:
herefore, there is the object of this invention in providing the image sensor which can always perform focus detection by an image surface phase difference system with high precision, and the imaging device using this image sensor.
Canon News suggests the company’s patent is describing a 20.7MP sensor, with 83 million focus detection points. The pixel size seems to be 4 micrometers, which would make that approximately 22mm on the width (5575×3725) or in other words an APS-C sized sensor.
The patent application states:
In order to achieve the above-mentioned object, the image sensor by the present invention, A plurality of optical waveguides which a unit pixel part provided with a plurality of pixels is the image sensor arranged by two-dimensional matrix form, and draw light to said plurality of pixels, respectively, It has the segregant formed among said plurality of waveguides, the height and position of the aforementioned segregant are changed according to image height, and the pupil distance of said plurality of pixels is changed in each of the aforementioned unit pixel part.
