New 21MP Exmor RS sensor adds HDR still images, faster focus on moving objects
Sony has unveiled a new model in its Exmor RS imaging sensor range for smartphones and tablets. The Exmor RS IMX230 module is a 21-megapixel model similar in size to those used in the Xperia Z2 and Z3 ranges, but it is claimed to be the first CMOS sensor for smartphones to have onboard image plane phase detection autofocus signal processing, allowing for quicker focusing on fast-moving objects.
Full HD 5-inch screen, water and dust-proofing also touted
Specifications for the Sony Xperia i1, known as the "Honami," have apparently leaked online. The rumored smartphone is said to be loaded with a 20.7-megapixel Exmor RS sensor, double that of most flagship smartphones but half that of Nokia's recently-launched Lumia 1020, along with a Sony "G Lens" and a discrete Bionz image processor.
Stacked sensor capable of HDR video recording
Sony has formally unveiled it stacked CMOS sensor for smartphones. Last seen in January, the Exmor RS camera modules boast a backside-illuminated CMOS sensor which stacks the pixel layer over the signal ship, shrinking the module's size. The two layers being independent of each other, combined with the pixel layer and analog logic chip not having to compete for space, promises improved image quality compared to previous methods.
