Sony started off the week by unveiling a new camera sensor that may be a clue as to both Sony and Apple plans. The backside-illuminated CMOS sensor stacks the pixel layer over the signal chip, shrinking the overall size. Image quality also benefits: with the two layers formed independently, and the pixel layer not having to compete for space with an analog logic chip, both the pixels and the signal chip layer can each be focused more on their respective tasks.
