Abstract
Disclosed herein is a light field camera, where both a curved shape of a curved microlens array and a curved shape of a curved image sensor are the same as a curved shape of a wide-angle main lens, and a sum of a reciprocal of a vertical distance between the curved microlens array and the curved image sensor and a reciprocal of a vertical distance between the curved microlens array and a virtual image plane of the wide-angle main lens is equal to a reciprocal of a focal length of the curved microlens array, which resolves a problem of poor image quality such as blurring and distortion that is caused when a wide-angle main lens is used in a light field camera and a flat microlens array and a flat image sensor cannot match a curved virtual image plane of the wide-angle main lens.
