Sony announces Exmor RS branding for its stacked camera sensors, promises brilliant HDR videos
We cannot talk about Sony smartphones without mentioning the Exmor R branded camera sensors, which the company has been using in its top-of-the-line models since 2009. Today, about three years after their commercial debut, Sony is introducing its Exmor RS sensors to the world, which are based on the CMOS imaging technology and incorporate the newly-developed "stacked structure" that we've been hearing about since January.

What makes the Sony Exmor RS sensors special is that their signal processing circuitry resides behind the layer of back-illuminated pixels instead of relying on conventional supporting substrates. As a result, the new sensor modules are physically smaller without sacrificing image quality. 

Quite the opposite – the RGBW coding technology that Sony has incorporated in its new sensors promises even better low-light performance when compared to today's BSI sensors. Moreover, the newly added HDR movie function allows footage to be recorded using two different exposure settings, thus expanding the dynamics range when shooting video. 

There are three camera sensors in Sony's Exmor RS lineup, and the 13-megapixel IMX135 is the leader of the gang. Next up are the IMX134 and the ISX014, both of which offer 8 effective megapixels. To no surprise, the company is also offering auto-focus modules built specifically for these sensors – one with a f/2.2 aperture and 5-element lens for the IMX135, and two f/2.4 4-element modules for the IMX134 and ISX014. These 13MP photo samples should give you an idea how good photos taken with Sony Exmor RS sensors should look like.

By now you are probably asking yourselves just when we might see a smartphone with an Exmor RS sensor. Well, keep an eye out for the Sony Xperia GX, in case you live in Japan. For everyone else there will be the Sony Xperia TX, which is said to be the international version of that smartphone. An announcement is expected later this month.
