A startup named InVisage promises to revolutionize the smartphone market with QuantumFilm, a new digital camera image sensor technology that it claims is four times more efficient at capturing light than traditional image sensor chips.
"With a tiny smartphone 3-megapixel sensor, we could make that a 12-megapixel sensor," said Chief Executive Jess Lee. "Or we could quadruple its sensitivity and ISO. That's the net benefit here." Higher sensitivity means photos that aren't as afflicted with the flecks of color that mean the sensor is capturing noise instead of what a person wants to photograph.
Essentially, the technology works by adding a new finely tuned light-sensitive layer on top of the silicon chip, Lee said. That layer is more efficient at converting incoming light into electrical signals, and the light isn't partially blocked by a microprocessor's metallic layers, either.
