Sony today said it has broken a new barrier in cellphone cameras through an update to its Exmor sensors. The company has shrunk the pixel size to 1.4µm and now says it can produce a 12.25-megapixel, 28mm equivalent CMOS camera small enough to fit in some cellphones. The unit gives a cellphone the image quality and detail of a modern point-and-shoot camera, according to the company.
