Abstract
A 2-wavelength image sensor has a plurality of uniformly dispersedly arranged visible radiation detectors and a plurality of uniformly dispersedly arranged, uncooled infrared radiation detectors, and a single visible radiation detector configures a visible radiation detecting pixel and four series connected infrared radiation detectors configure a thermal infrared radiation detecting pixel. Consequently a visible image can be four times a thermal image in resolution. Furthermore for an infrared image an area increased four times per pixel to receive light can be achieved. As a result the infrared image can be enhanced in temperature resolution.
