Abstract Chromatic adaptation refers to the sensing and preprocessing of spectral composition incident light on retina, it is important for color‐image recognition. It challenging apply sensing, memory, processing functions color images via same physical process using complementary metal–oxide–semiconductor technology because redundant data detection, complicated signal conversion processes, requirement additional memory modules. Inspired by highly efficient chromatic human a 2D oxygen‐mediated platinum diselenide (PtSe 2 ) device presented simultaneously images. The exhibits wavelength‐dependent bipolar photoresponse linear pulse‐number dependence photoconductivity, which dominated photon‐mediated adsorption desorption oxygen molecules bilayer PtSe . proposed retinomorphic shows superior image classification accuracy (over 90%) compared an independent pseudocolor channel (less than 75%). Hence, promising developing artificial vision perception systems with reduced architectural complexity.
