a Schematic of the Day-Night camera using an ICR device. b Schematic of the selective transmission of Bayer filter for visible and infrared light. c The photos taken by the commercial camera with and without ICR, showing the color distortion caused by infrared interference. d Schematic of imaging equipment. Three colors of lasers are used as the target light, and 940 nm LEDs are used as interference light. Color reproduction ability of perovskite photodetectors (e) and Si photodetector (f). g Imaging results of a 16-step grayscale test chart. Below each step is the corresponding optical density (OD). 940 nm LEDs are used as the light source for the grayscale test. h The grayscale values corresponding to the imaging results. The inset shows the grayscale resolution of the grayscale test chart at low optical power after overexposure.
