  • Sony has introduced a stacked camera sensor for smartphones.
  • This tech sees photodiodes and pixel transistors occupying completely different substrates.
  • Sony says this innovation will result in elevated dynamic vary and diminished noise.

Sony is among the world’s main camera sensor producers, alongside the likes of Samsung and Omnivision. The firm is mostly on the cutting-edge of smartphone images, and it’s simply introduced one other promising innovation within the house.

The Japanese agency introduced what it calls the world’s first stacked CMOS picture sensor with “2-Layer Transistor Pixel.” So what precisely does this imply?

Whereas standard CMOS picture sensors’ photodiodes and pixel transistors occupy the identical substrate, Sony’s new expertise separates photodiodes and pixel transistors on completely different substrate layers.

Sony additionally posted a picture to present individuals a better thought of what’s modified in comparison with standard sensors. You can view this image beneath.

Sony says this resolution doubles a sensor’s saturation sign degree and subsequently leads to wider dynamic vary. The agency provides that shifting the pixel transistors to a separate substrate frees up house to extend the dimensions of so-called amp transistors. It explains that bigger amp transistors lead to notably diminished noise, which needs to be useful for low-light images. The firm provides that this tech will permit a sensor’s pixels to take care of or enhance their current efficiency even at smaller pixel sizes.

In different phrases, it seems like Sony thinks this tech could possibly be key for greater decision smartphone cameras with smaller pixels. So this could possibly be an essential enabler if the corporate needs to comply with in Samsung’s footsteps and supply 108MP or 200MP cameras.

Sony confirmed that this tech is supposed for smartphones, however didn’t give a timeline for after we ought to count on to see the primary sensors with this format. Nevertheless, it’s nonetheless fairly fascinating to see camera sensor producers persevering with to innovate on this house.
