When Sony nominated Kaz Hirai to lead the corporation, he laid out an ambitious strategy that he titled One Sony. Hirai identified three key markets where he wanted Sony to be a leader: digital imaging, gaming and mobile, with the trio pushed accordingly. Five years later, and Hirai's managed to hit two out of three targets, with Sony's most recent financial reports vindicating his plan.

In the former category, is Sony's lucrative digital image sensor business that provides the chips for pretty much every smartphone worth a damn. Bloomberg believes that Sony sensors are now found inside half the world's phones, and given that many use dual lenses on the back and one up front, that's a healthy bounty for Sony.
