Abstract

High quality imaging camera adaptable for various light environments are highly desirable in artificial visions for autonomous vehicles and drones. The cephalopod vision, especially the cuttlefish eye composed of a W-shaped pupil, a hemispherical lens, and a curved retina with densified pixel distribution and polarization recognizing microvilli, inspires a novel camera system. Here, we report an artificial cuttlefish eye camera, which enables high-contrast and high-acuity imaging by balancing vertically uneven light environments via the W-shaped aperture, by focusing on target visual regions with high resolution via pixel density distribution, and by recognizing the polarization noise via the flexible film polarizer.
