Sony Introduced World’s Highest Resolution Camera Sensor for Phones

Sony announced "IMX586" a new image sensor for smartphones. The sensor features 48 effective MP (8000x6000 pixels). The Sony IMX586 48MP sensor is expected to arrive in future smartphones soon for better daylight photos that render great detail.

Sony confirmed that the sample shipments will begin from September and the price of the sensor(IMX586) will be approximately Rs.1800 excluding additional taxes that vary with each country. IMX586 stacked CMOS image sensor for smartphone cameras sports 0.8 micron pixels and this miniaturisation of pixel size could affect low light photography, capturing more noise. This could result in poor light collecting efficiency per pixel, accompanied by a drop in sensitivity and volume of saturation signal. To overcome this, Sony uses the technique as Huawei of combining four pixels to raise sensitivity and delivering a 12MP image.

They say that Sony has used the "Quad Bayer colour filter array, where adjacent 2x2 pixels come in the same colour, making high-sensitivity shooting possible. During low light shooting, the signals from the four adjacent pixels are added, raising the sensitivity to a level equivalent to that of 1.6-micron pixels (12 megapixels), resulting in bright, low noise images and videos. When shooting bright scenes such as daytime outdoors, the built-in, original signal processing function performs array conversion, making it possible to obtain high-definition 48 effective megapixel images in real time."

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. It sports Sony's exposure control technology and signal processing functionality enabling a dynamic range that is claimed to be four times greater than conventional products. It also brings features like image plane phase-difference AF, HDR imaging, and supports 4K shooting as well, at up to 90fps, while 1080p recording goes up to 240fps, and 720p recording goes up to 480fps. At full resolution, it can only record video at 30fps.
