Sony has unveiled a new mobile imaging sensor that provides an incredible upgrade over any mobile camera that we have seen till date. The new image sensor employs the industry's first 3-stacked CMOS sensor mechanism, using 1GB of DRAM as the sensor's buffer memory. The exceptionally large buffer size is placed in between a conventional 2-layer backside-illuminated CMOS image sensor. What this primarily allows is exceptionally fast readout speed of photographs (time taken to shoot and process one photograph), and the new sensor can produce 19.3 megapixel photographs in 1/120th of a second - four times faster than the industry standard right now. The sensor also does this with minimal focal plane distortion when shooting fast moving objects, thereby drastically improving the paradigm of a smartphone's camera performance.
