Imaging device

Abstract

The present disclosure relates to an imaging device capable of reducing a mask of a lensless camera. The mask modulates the incident light to convert the incident light into modulated light, the imaging element captures a modulated image including the modulated light, and the reconstruction unit reconstructs an image corresponding to the incident light on the basis of the modulated image. At this time, the mask condenses the incident light transmitted through the transmission region and changes the optical path of the condensed incident light to realize the point spread function same as the reference mask realized by two-dimensionally arranging the transmission region that transmits the incident light and the light shielding region that shields the incident light. The present disclosure can be applied to a lensless camera.
