Sony develops Next-generation Back-Illuminated CMOS Image Sensor

Sony announced its next-generation back-illuminated CMOS image sensor. With this new image sensor they promise further enhancement in image quality, superior functionalities and a more compact size that will lead to an enhanced camera. This development is aimed at the highly complicated smartphone market. With the advent of this new sensors Sony hopes to boost their smartphone sales and there is no doubt they will achieve it.

As the first step, Sony has developed a model with built-in signal processing functionality. Samples will be shipped from March, 2012. Models have been developed with Sony’s unique RGBW Coding function, which facilitates low noise, high quality image capture even in low light condition, and HDR (High Dynamic Range) Movie function, for excellent color management in extremely bright light conditions.

What’s new:

  • Large-scale signal processing circuits required for higher image quality and better functionality are built-in.
  • More compact image sensor chip size.
  • Even higher image quality of the pixel section by adopting manufacturing processes specialized for superior image quality.
  • Faster speeds and lower power consumption by adopting the leading process for the circuit section.

Conceptual diagram of the sensor:

RGBW Coding function

“RGBW Coding” function which adds W (White) pixels to the conventional range of RGB (Red-Green-Blue) pixels has realized higher sensitivity, enabling high-quality shooting with low noise even in dark indoor or night settings.

HDR (High Dynamic Range) Movie

“HDR Movie” function enables brilliant colors to be captured even in settings with a wide range of light including bright light.
