For the past several years, improvements in smartphone cameras have followed the "more megapixels" mantra. Samsung's Galaxy S5 is up from 13 to 16 megapixels; Sony's new Xperia Z2 packs a 20.7-megapixel Exmor model; and Nokia's Lumia 1020 with PureView is a 41-megapixel monster. However, Google's recent sensor-laden smartphone prototype, Project Tango, could herald a new direction.
Though Mountain View is focused on 3D mapping, so-called depth camera tech could dramatically improve all the pictures you take with your smartphone. By using two lenses with different focal lengths, for example, you could zoom in on subjects with quality that rivals bulky optical zooms. It could also eliminate a number of other shortcomings without adding an awkward hump like the one seen on the Lumia 1020. You could soon have much better light sensitivity, less noise and depth of field control that rivals a DSLR. The benefits are clear, but Google is not alone in its pursuit. The battle for a better smartphone camera is on, and you could be the one to reap the rewards.
