Sony has announced the upcoming release of the IMX586 stacked CMOS sensor for smartphone cameras. The sensor features 48 effective megapixels, the highest available.

The new product achieved a world-first ultra-compact pixel size of 0.8 μm, making it possible to pack 48 effective megapixels onto a 1/2-type (8.0 mm diagonal) unit, thereby supporting enhanced imaging on smartphone cameras.

Sony says the 48MP sensor will rival that of high-performance SLR cameras, making it possible to capture beautiful high resolution images with a smartphone.

The new sensor uses the Quad Bayer color filter array, where adjacent 2x2 pixels come in the same color, 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 μm pixels (12 megapixels), resulting in bright, low noise images. 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. Even scenes with both bright and dark areas can be captured with minimal highlight blowout or loss of detail in shadows.

Here's a closer look at the main features of the sensor...

World’s first 0.8 μm ultra-compact pixel size enables industry’s highest pixel count at 48 effective megapixels
Generally, miniaturization of pixels results in poor light collecting efficiency per pixel, accompanied by a drop in sensitivity and volume of saturation signal. This product was designed and manufactured with techniques that improve light collection efficiency and photoelectric conversion efficiency over conventional products, resulting in the world’s first 0.8 μm pixel size, with both high sensitivity and high saturation signal level.

This smaller pixel size allows the new product to deliver 48 effective megapixels on a compact unit with 8.0 mm diagonal, which can be fitted on many smartphones. The increased pixel count enables high-definition imaging even on smartphones which use digital zoom.

The Quad Bayer array enables both high sensitivity and high resolution
By adopting the Quad Bayer color filter array, where the adjacent 2x2 pixels come in the same color, the new sensor delivers both high sensitivity and high resolution. 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. 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.

Four times greater dynamic range than previous products and real time output
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. Even scenes with both bright and dark areas can be captured with minimal highlight blowout or loss of detail in shadows while viewing the image on the smartphone display.

Pricing and Availability:
Sony says samples of the new sensor are set to ship in September 2018 for 3,000 JPY (26.93 USD). It's possible that Apple could use this sensor in its future iPhones models.

Nokia Lumia 1020 was 41mp. Still waiting for a camera as good as that. Looks like we are finally getting one.

The Lumia achieved that because of how huge the lens and sensor was, I mean look at it taking up all that space.

The camera bump was actually pretty good as a grip/finger rest.

Now AS.Samaung can focus on being better than these people, but talk about effort. Is it still okay to argue how phone cameras are as of now outdoing DSLR cameras, or is it still a long shot?
