InVisage promise better cameras for mobile phones

Digital Photography Review reports: [edited]

InVisage Technologies has announced sensors it says can offer four times better performance than conventional CCD and CMOS sensors. The company's 'QuantumFilm' technology uses the unique electronic behavior of quantum dots (precisely-sized nano-scale crystals trapped in a polymer film) to replace conventional silicon photodiodes.

The company says the quantum dots themselves are twice as sensitive to light as conventional photodiodes and that their placement on the sensor surface offers a further doubling of sensitivity over front-illuminated CMOS designs. The film can be positioned on conventional circuitry, allowing the chips to be produced more cheaply than CMOS or CCD designs.

The company says that only prototypes exist at present, with samples chips going into production in Q4 of 2010 and full production starting in 2011.
