BusinessWire: Panasonic developed a technology of electrical control of the NIR light sensitivity in an organic CMOS image sensor. The sensitivity of all the pixels in the image sensor, which has directly stacked organic films, is simultaneously controlled by changing the applied voltage to the organic films.
This technology enables to switch between modes of color imaging and NIR imaging frame by frame without a mechanical IR cut filter. The extinction ratio of NIR sensitivity at 800 nm was -28 dB. The technology also enables global shutter operation and is suitable for industry such as machine vision applications.
Panasonic holds 94 Japanese patents and 68 overseas patents (including pending) related to these technologies.
