Abstract: The present disclosure provides a waveguide display apparatus. The waveguide waveguide display apparatus of the present disclosure is a waveguide display apparatus for correcting curved surface reflection distortion, the waveguide display apparatus including a waveguide for guiding light inputted from the outside; a first diffractive optical element disposed at the waveguide, and diffracting the light inputted from the outside to the inside of the waveguide; and a second diffractive optical element disposed at the waveguide, and diffracting the light guided by the waveguide to output a plurality of diffracted lights in a direction of a curved surface reflector located outside, wherein the second diffractive optical element has a structure of a diffraction grating corresponding to a curvature of the curved surface reflector such that the diffracted lights are reflected at different locations of the curved surface reflector in directions parallel to each other.

Abstract: Provided is an image capturing method performed by an image capturing apparatus, including acquiring information on first positions which are current positions of a sensor and a generator, moving the sensor and the generator to second positions which are positions at which an image having a magnification power different from a magnification power of an image of an object acquired when the sensor and the generator are located at the first positions is acquired, and acquiring an image of the object, wherein the sensor and the generator move the same distance so that a distance between the sensor and the generator is not changed.
