iPhone 6 Camera Features "Focus Pixels"

Apple iPhone6 and iPhone6 Plus smartphones feature new 8MP camera and sensor. While keeping the same pixel size and count, the new sensor features "Focus pixels" and 1080p60 video with HDR mode and "auto image stabilization" (on top of OIS in 6 Plus model and EIS in iPhone 6):

"Focus Pixels are enabled by the new Apple-designed image signal processor. They provide the sensor with more information about your image, giving you better and faster autofocus that you can even see in preview."

"Auto image stabilization makes up for motion blur and hand shakiness by taking four photos with a short exposure time. Then the best parts of those photos are combined into one image with as little noise, subject motion, and hand shake as possible."

    1.5um unit cell and 8M pixels, which is the same as 5s.
    no pixel scaling unexpectedly.

      By increasing Aperture (f2.4 -> f2.2), it can only get 20% more lihgt. Somehow the pixel size becomes bigger, like 1.9um -> 2.4um?

    The phone is too thin, no place for a larger sensor size. The curved sensor with thinner lens would have been useful though. Maybe the iphone 6S will use it. The main camera improvements have typically been introduced in the "S" versions of the iphone..

      I saw some websites (ie Phonearea) saying the sensor size is 1/2.6" (vs 5s 1/3"). This looks incorrect, right?

    They added focus pixel on the image sensor. I guess this explains why sensor size is bigger, while the same pixel count (8mp)and pixel area (1.5um), doesn't it?

    What are "focus pixels"? Is it the same technology as Lytro's multi-aperture camera?

      It's similar to phase detection in the Galaxy S5 and Note 4 ISOCELL sensor. Nothing new here.
