a Schematic illustrating the architecture of the organic neuromorphic imager and associated electric circuit of chip pixels. Standard imaging mode. Images of a car model (b) and desk tidy (c). d Images of two cars (blue and green), a red traffic cone model and a color card captured by the organic neuromorphic imager using red, green and blue optical filters (left), and the reconstructed full visible color images (right). e Standard mode. The histogram distribution of each pixel’s response in the organic neuromorphic imager under dark conditions, after 5 s of light exposure, and 5 s post-light removal. f Synapse mode. The histogram distribution of each pixel’s response in the organic neuromorphic imager under dark conditions, after 5 s of light exposure and at 5, 25, and 100 s post-light removal. g Imaging pixel numbers of neuromorphic imagers over the years.
