This paper describes an RGB-infrared (IR) organic CMOS image sensor with electrically controllable IR sensitivity. The sensitivities of all the pixels in the image sensor, which has the structure of two directly stacked organic layers with a high resistance ratio, are simultaneously controlled by changing the applied voltage to the organic films. The fabricated image sensor, with a pixel pitch of...
The use of infrared (IR) imaging to view scenes otherwise invisible to the human eye, simultaneously with visible-spectrum imaging, is increasingly of interest for various applications for such as in-vehicle, surveillance, and agricultural security cameras. The loss of spatial resolution in conventional RGB-IR sensors causes aliasing, because IR pixels are segmented within the provided effective pixel...
Image sensors are increasingly becoming key devices for various applications (in-vehicle, surveillance, medical, and so on). To realize the best possible imaging and sensing performance, there is growing demand for extended dynamic range that can precisely reproduce color tone. Several conventional papers have described methods for enhancing dynamic range, such as multiple exposures in a frame [1]...
