Claim 16:
17. A method for transferring light in a camera, comprising:
diffracting, using an optical correction structure, at least some of light having passed through a monocentric lens to a fiber bundle, wherein the optical correction structure:
includes a diffractive optical element located in a region outside a central region at two sides of the optical correction structure that respectively face the monocentric lens and the fiber bundle; or
includes a hole located at the central region of the optical correction structure;

wherein the optical correction structure is configured to diffract the at least some of light so as to increase light in-coupling between the monocentric lens and the fiber bundle, relative to other light in-coupling that would occur between the monocentric lens and the fiber bundle without diffracting the at least some of light using the optical correction structure; and
transferring, using the fiber bundle, the at least some of light from the optical correction structure to an image sensor.
