“HTC is to use a new camera sensor on its much-rumoured HTC M7 smartphone, Pocket-lint can confirm, which will use what the company calls Ultrapixels. Although rumours have suggested the new smartphone will use a 13-megapixel sensor, sources familiar with the matter have told Pocket-lint that won’t be the case. Well, not exactly.The new camera will instead be made up of three 4.3-megapixel sensor layers combined to give a resulting single image. Three lots of 4.3 may add up to around 13-megapixels, but images from HTC’s latest won’t be output at that larger size.”
