1. A light field camera, comprising:
a wide-angle main lens, configured to acquire an image signal and image the acquired image signal, wherein, on a virtual image plane of the wide-angle main lens, a distance between an image point and an optical axis is directly proportional to a distance between an object point corresponding to the image point and the optical axis; and a curved imaging array comprising a curved microlens array and a curved image sensor, wherein the curved microlens array is configured to reimage an image formed through imaging by the wide-angle main lens, and record, on the curved image sensor, an image formed by means of reimaging; wherein both a curved shape of the curved microlens array and a curved shape of the curved image sensor are the same as a curved shape of the virtual image plane of the wide-angle main lens, and wherein 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 the virtual image plane of the wide-angle main lens is equal to a reciprocal of a focal length of the curved microlens array. |
