Abstract
The present invention discloses an image sensing chip, comprising: a substrate; a photodetector array, comprising a plurality of photodetectors formed on the substrate; wherein, by adjusting the light responsivity of the plurality of photodetectors, the plurality of photodetectors are made to output corresponding photocurrents in a superimposed manner when identifying an image to be identified. By adjusting the light responsivity of each photodetector in the photodetector array, the plurality of photodetectors are made to output different photocurrents in a superimposed manner when identifying different images to be identified, and by detecting the photocurrents in the superimposed output of the photodetector array, the shape of the image to be identified can be identified.
