The imaging industry has seen quite a few new photographic technology developments recently, and here comes another: Fujifilm and Panasonic report they’ve jointly developed an organic CMOS image sensor technology that will yield higher dynamic range and sensitivity “for vivid and texture-rich images.”
Using an “organic photoelectric conversion layer” developed by Fujifilm, the sensor will have a higher absorption coefficient when it comes to receiving light than a comparable silicon-based photodiode. Panasonic combined the organic layer with its semiconductor technology for a sensor 1.2 times more sensitive than conventional ones, and with a promised 88dB dynamic range.
A conventional image sensor combines a silicon photodiode, metal interconnect, color filter, and on-chip micro-lens, the companies say. The photoelectric conversion layer made of organic materials, at 0.5 microns, is one-seventh the thickness of silicon, and can “harvest all the light received on the sensor” to boost sensitivity.
