Google's Pixel 2 XL is considered the best low-light smartphone camera and its sensor only boasts 1.4 micrometers of pixel pitch.

Sony, the company that struggles selling its own smartphones but is very good at building camera sensors for other companies' phones, has announced its new IMX586 CMOS image sensor for smartphones. Sample shipment planned date is for September of this year, and OEMs that will decide to feature the new Sony IMX586 chip can expect improved results.

The IMX586 CMOS image sensor is smartphone-compatible, as it comes in a compact 8.0mm diagonal unit and enables HD imaging even on smartphones with digital zoom.

"Original Sony exposure control technology and signal processing functionality are built into the image sensor, enabling real-time output and a superior dynamic range that is four times greater than conventional products", the company notes.

As we all know, just increasing the pixel count doesn't automatically mean the image quality is going to be better.

What this means is that even highly contrasted scenes featuring both bright and dark sections can be captured in detail with little highlight blowout.

The Sony IMX586 is equipped with Quad Bayer colour filter array that offers 2×2 pixels in the same colour for higher sensitivity shooting.

Capture more detail with more megapixels. In low light situations, such as shooting at night, the signal from the four adjacent pixels are added, raising the sensitivity to a level equivalent to that of 1.6 μm pixels (12 effective megapixels), to capture bright, low-noise photos and videos.

'Generally, miniaturization of pixels results in poor light collecting efficiency per pixel, accompanied by a drop in sensitivity and volume of saturation signal, ' Sony says.

In addition to this, Sony's also shrunk the pixel size down to an impressive 0.8 μm.

Sony's image sensor business so far has been quite profitable racking in $5.9 billion in revenues in 2017.
