![]() As a result, unlike conventional silicon image sensors, it is possible to provide photoelectric conversion characteristics that do not depend on the physical properties of silicon. Hamamatsu organic CMOS image sensors have an organic thin-film photoelectric converter that converts light into an electrical signal, and an underlying circuit that stores and reads out signal charges. Accurate color reproduction and color recognition and judgment were difficult. Since it can achieve spectral characteristics with low color mixing, accurate color reproduction is possible regardless of the type of light source.Ĭonventional Bayer array silicon image sensors do not have sufficient color separation performance for green, red, and blue. This unique layered structure reduces the sensitivity of each pixel in green, red, and blue in wavelength regions outside the target range. In this technology, the organic thin film that performs photoelectric conversion and the circuit that stores and reads out electric charge are completely independent of each other. has developed excellent color reproduction technology that suppresses color mixture by thinning the photoelectric conversion layer using the high light absorption rate of the organic film and by using electrical pixel separation technology.
