Panasonic have this week demonstrated a new sensor technology that captures up to three times more dynamic range than a conventional sensor. According to the report by CNET News, Panasonic’s Tokayoshi Yamada has demoed a 177x144 pixel image sensor that takes three photos at different shutter speeds and combines them into a single image that can span a dynamic range of 140 decibels (“ordinary” sensors achieve 60 decibels).

“In his presentation, Yamada showed a resulting image taken of a regular incandescent light bulb. With conventional sensor technology, a few of the words printed on the bulb were visible, but most were washed out in a blown-out white patch near the bulb’s filament. In the Panasonic sensor’s image, not only were most of the words visible, but also the helical coil of the filament was.”
