Olympus develops advanced hybrid autofocus sensor

   Recently, a patent from Olympus has been exposed. The patent shows that the company is developing an advanced hybrid autofocus sensor.

   The sensor is designed by the camera manufacturer, but it is outsourced to a third party to manufacture, which is not exactly the same as using a third-party sensor. Therefore, most camera manufacturers, including Fujifilm, Nikon, and even now Canon, do this. In the new patent, Olympus is working to improve the hybrid sensor autofocus system. The patent was granted in February this year. We hope to see a new generation of hybrid AF sensor in the upcoming Olympus flagship camera.

   Patent details

   In an imaging device with multiple imaging pixels and multiple focus detection pixels, where The position of the opening of the light receiving unit is shifted relative to the imaging pixel.

The focus detection pixels of the first focus detection pixel group include a plurality of focus detection pixels with different opening positions that are shifted in the first direction , Which corresponds to the first color filter of the imaging pixel. For each focus detection pixel with a different opening position, it is arranged at a first pixel pitch in the first direction.

   The focus detection pixels of the second focus detection pixel group include a plurality of focus detection pixels. The opening of the focus detection pixel is shifted in a second direction different from the first direction, and the position of the opening is different from the first detection pixel of the imaging pixel. At a position corresponding to a second color filter of a color filter having a color different from 1, each focus detection pixel having a different opening position is arranged at a second pixel pitch in the second direction.
