Sony’s Smartphone division latest stacked CMOS design, the IMX 586 promises a leap in image quality by increasing the resolution to 48 effective megapixels. Image quality isn’t simply a matter of adding more megapixels as that can be counterproductive. The 0.8-micron pixels used in this sensor will be the smallest on the market. But, Sony says it’ll get around this by using a quad Bayer color filter array and allowing each pixel to use signals from the four adjacent pixels, which supposedly raises light sensitivity to the equivalent of a 12-megapixel image captured with 1.6-micron pixels.
