In an attempt to further optimize the image quality of small smartphone sensors, Samsung has developed a new technology called ‘ISOCELL’, which promises better color accuracy, less noise and greater dynamic range as compared to current BSI (back-side-illuminated) CMOS sensors. Basically, what Samsung did was to put physical barriers inbetween individual pixels (hence the name: ISOlated CELLs), which greatly reduce light spill as well as crosstalk between pixels. Samsung calculates that this new technology will decrease crosstalk between individual pixels by as much as 30%, meaning more light will be captured by each individual pixel.
A first sensor using this new technology has been created, sporting 8 megapixels on a 1/4″-type device. Mass production of the new sensor is scheduled for Q4 2013, so we might actually see it featured in smartphones or tablets some time next year.
