When smartphones are encroaching on compact cameras' turf, how does a company try to stay relevant making sensors for those cameras? By upping the resolution, of course. Toshiba has given a peek at the TCM5115CL, a 1/2.3-inch, backside-illuminated CMOS sensor that hits 20 megapixels -- a big jump from the 16-megapixel sensors in many point-and-shoots and some smartphones. To combat the noise and sensitivity problems that usually come with a denser design, the electronics giant is using pixels that can absorb 15 percent more of a charge, and therefore more light. Toshiba has primed the sensor for high-speed shooting and video as well, with the potential for 1080p video at 60FPS and 30FPS burst shooting at full resolution, provided the processor can keep up. We're not bracing ourselves for an imminent renaissance among dedicated cameras, however. Mass production doesn't start until August, which suggests we're unlikely to have 20-megapixel shooters in our pockets during summer vacation.
