Sony Corporation has announced a new improved stacked CMOS image sensor for smartphone cameras and other devices that offers a more sophisticated image capturing. The new sensor called Exmor RS IMX230, is type 1/2.4 with 21 effective megapixels featuring a compact size, better image quality and enhanced functionality.

The IMX230 is the first stacked CMOS sensor to offer image plane phase detection AF signal processing function that can focus track fast moving objects such as vehicles or pets. The new sensor’s HDR (High Dynamic Range) function captures the images much clearly and vividly, even the high-contrast ones and it now also supports high-resolution 4K (4096 x 2160) video recording as well as still image. Sony also plans to develop a 16 MP stacked CMOS image sensor having the same image plane phase detection AF signal processing and HDR imaging functionality by next year.

The new Exmor RS sensor features a chip with signal processing circuits having a stacked pixel section of back-illuminated pixels on top. Such a stacked imaging sensor is compact in size but at the same time offers improved image quality and functionality.
Sony gives the date of shipment of the new IMX230 sensor as April 2015 and the sample price as 2,100 yen (About US$18)
Following are the Key Specifications of the new Exmor RS IMX230 stacked CMOS image sensor:
