Despite climbing megapixel counts, cameraphones still don’t seem to offer the same photographic performance as a dedicated point-and-shoot. Startup InVisage hope to change all that – and revolutionise the digicam market along the way – with their new QuantumFilm image sensor tech: they reckon it’s capable of 4x the sharpness of current cameraphone CMOS sensors, along with offering twice the dynamic range. If that doesn’t mean much to you, then how about a 12-megapixel iPhone camera in the same amount of space the current 3-megapixel sensor occupies.

At the heart of the technology is InVisage’s new quantum dot material, which replaces the traditional CMOS sensor and is far more efficient at capturing light. A CMOS is only good for around 25-percent of the light that actually falls on it, whereas the QuantumFilm sensor can capture 90 to 95-percent of light.
Because there’s more light, that means more details in the end-picture, and since the quantum dot material is more efficient it’s actually cheaper than high-resolution CMOS sensors. InVisage expect production of the QuantumFilm sensor to kick off in Q4 2010, with products using it – including cameraphones, digital cameras and more – to arrive on the market in 2011.
