Sony Plans HDR-Ready CMOS Sensor for Phones

Posted by at 2:53 pm on January 23, 2012

Sony started off the week by unveiling a new camera sensor . 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.

The sensor uses Sony’s newest RGBW processing, which improves dynamic range and can be used for an HDR (high dynamic range) movie mode that Sony claims will preserve color accuracy even in bright light. New processing techniques help curb the extra noise that’s introduced by the white pixel.

Both 13- and eight-megapixel versions of the sensor will be in test sampling as of March. Shipments are expected in June for the 13-megapixel version and August for the eight-megapixel edition. None of the Xperia smartphones Sony has unveiled so far has use the new sensors. BUt New Phone by Sony should be shown at Mobile World Congress next month.
