Next iPhone Killer Camera Will Come with 21MP Image Sensor Made by Sony

Apple Supplier Sony Unveils Updated Stacked CMOS Image Sensor


AppleSupplier Sony, has recently unveiled an updated stacked CMOS image sensor for smartphones, featuring 32 effective megapixels, on-chip phase detection AF and 4K video recording. The chip is said to be 1/2.4 inch type with square pixels which measures about 1.12um x 1.12um each with video of up to 4K resolution available with HDR function which is also available in still mode. Sony’s previously introduced HDR movie feature now makes its way to this chip.

The sensor utilises a backside illuminated configuration which was earlier introduced by Sony known as Exmor RS with layer of signal processing circuits beneath a layer of backside illuminated pixels and boasts of a total of about 192 AF points with signal processing which is incorporated in the image sensor.

The on-sensor phase tends to detect autofocus and processing eventually resulting in faster and a much accurate autofocus together with improved subject tracking. A mention is also made in a press release of another upcoming sensor, which is a 16 MP stacked sensor having phase-detection AF which would be coming up by the end of the next fiscal year and the IMX230 unit would be shipped by April 2015.


IMX230 Sensor – First CMO Sensor

Apple has been using Sony sensors for its iPhone and iPads and hence it is likely that Sony’s stacked sensor technology would be used in the iOS devices in the near future. The 21 megapixel Exmor RS IMX230 sensor is created with a chip which stacks a pixel section with a circuit section on top of one another enabling Sony to build improvements in each aspect of the individual sensor resulting in dramatic improvements.

Since 2012, Sony has been stacking sensor technology though the latest sensor would be introducing new autofocus together with HDR technology. As per Sony, the IMX230 sensor is the first CMO sensor for smartphone which has plane detection autofocus signal processing providing a much faster tracking of moving subjects which occur instantaneously.

The sensor which supports a full 21 megapixel HDR images and 4K HDR video results in improved lighting in high contrast scenes and the High Dynamic Range – HDR imaging captures images with different exposures together into one image which improves the detail and colour.


Sony’s Plan for 16 Megapixels Version of IMX230


High megapixel sensors are not used by Apple in its iPhone or iPad and Sony has plans in producing a 16 megapixel version of the IMX230 by 2015 which would be just right for iOS devices. There is a possibility that Apple would use the 16 megapixel version of the IMX230 in the 2015 iPhone 6s as well as 6s Plus though it could also be possible that the sensor would not be used till 2016 or later on since Apple tends to utilise older sensors in its devices.

The sensor used in the present iPhone and iPad is not known though camera experts are of the opinion that the iPhone 6 and 6 Plus have the Sony ISX014 sensor which is an 8 megapixel sensor that was first introduced by Sony in October 2012.
