Abstract Physical reservoir‐based reservoir computing (RC) systems for intelligent perception have recently gained attention because they require fewer resources. However, the system remains limited in infrared (IR) machine vision, including materials and physical expression power. Inspired by biological visual systems, study proposes a near‐infrared (NIR) retinomorphic device that simultaneously perceives encodes narrow IR spectral information (at ≈980 nm). The proposed device, featuring core‐shell upconversion nanoparticle/poly (3‐hexylthiophene) (P3HT) nanocomposite channels, enables absorption conversion of NIR into high‐energy photons to excite more photo carriers P3HT. photon‐electron‐coupled dynamics under synergy photovoltaic photogating effects influence nonlinearity high dimensionality RC narrow‐band irradiation. also exhibits multilevel data storage capability (≥8 levels), excellent stability (≥2000 s), durability (≥100 cycles). accurately identifies static dynamic handwritten digit images, achieving recognition accuracies 91.13% 90.07%, respectively. Thus, tackles intricate computations like solving second‐order nonlinear equations with minimal errors (normalized mean squared error 1.06 × 10⁻ 3 during prediction).
