Sony IMX586 will cram 48 megapixels into smartphone cameras

Obviously, this sensor will have to be tested out in various lighting conditions to make sure of this claim but smartphones, in general, have always struggled in low-lighting conditions.
Sony's IMX586 sensor should appear in smartphones as of next year, as the company is now planning on shipping samples in September for 3,000 yen ($27) each. That conversion is how the company arrives at that 48-MP effective resolution.
With 48 effective megapixels (8000×6000), the IMX586 chip features a Quad Bayer color filter array, meaning adjacent 2×2 pixels come in the same color, "making high-sensitivity shooting possible".
But it's worth taking a look outside the box, as Nokia introduced smartphone cameras with 40MP years ago, the Nokia 808 PureView and Lumia 1020, which were twice the size of the IMX586's sensor and therefore had significantly larger pixels that could capture more light. In addition to these advantages, original Sony exposure control technology and signal processing functionality are built into the image sensor, enabling real-time output and a superior dynamic range four times greater than conventional units.
Sony has just announced a new CMOS sensor for smartphones that captures 48-megapixel photos - the highest pixel count in the industry.
"Even scenes with both bright and dark areas can be captured with minimal highlight blowout or loss of detail in shadows".
"These days, high-end smartphone models require even greater imaging quality from their cameras", Sony says. Sony's 0.8-micron pixels are now the smallest on the market, however its use of a quad Bayer colour filter array helps each pixel coordinate with those that surround it to essentially create a larger pixel. In low-light pictures, the signals from the four neighboring pixels are added, Sony says, which raises the sensitivity to a level equivalent of 1.6μm pixels (12-megapixel).
