OmniVision brought out a new camera sensor on Thursday that it hoped would lead to even thinner phones and tablets as well as better photo quality at the same time. Its OV8850 still shoots at the now common eight megapixels but, as the first from the company to shrink pixels down to 1.1 microns, gets a much reduced size. The autofocus elements are about 20 percent thinner and lead to a design just 4.7mm (0.19in) thick, or good enough for 'ultra-slim' devices.
