"Furthermore, the system dump confirms that it will be able to shoot photos at 20MP resolution (5248 x 3936 pixels), and that it will also feature a new Super Resolution algorithm that will enable it to record videos at 4K (4000 x 2000)."
"A system dump for a Sony phone with model number C6906 -- believed to represent the rumoured Xperia i1 'Honami' phone that's been spied several times in recent weeks -- has been pulled apart on the XDA Developers forum and helpfully collated at XperiaBlog.
Alongside a four-core Qualcomm Snapdragon 800 processor, the 'system dump' points to the power to take photos at a 20-megapixel resolution.
This is said to be done using a 'Super Resolution' tweak, so it's possible the phone won't actually have a 20-megapixel sensor, but will make up that resolution using some natty pixel-adding software.
The power to record video at 4,000x2,000 pixels is also reportedly on board."
