NEW CAMERA

In general as we know that the sensor phase AF pixels doesn’t capture image, they create a dead pixel and later on it covered by certain type of image processing algorithms implemented by camera manufactures.

But Fujifilm latest patent shows a Hybrid AF pixel that minimizes the image quality degradation and manages to capture light as well as it can be used for AF purpose.

• Fujifilm patents
  • Image plane phase difference AF
  • Dimming element
    • The amount of transmitted light is changed according to the voltage applied
    • Electrochromic devices were laminated in this order the transparent electrode, the oxidation coloring layer, an ion conductive layer, the reduction coloring layer, a second transparent electrode of the first
    • Opaque, to function as a transparent at the time of imaging the image plane when the phase difference AF

Canon is the first Camera manufacture to implement Hybrid AF Pxiels technology

Canon is first camera manufacture to use Hybrid / Dual-AF pixel technology, the Canon Dual-Pixel AF technology features two separate photodiodes for each pixel. One half of the total photodiodes track image coming from one side and other half tracks the image from the other half and finally the amount of lens drive is calculated from the amount of signal difference. When the signals of two photodiode are in agreement the Focus is achieved.
