Abstract: An aberration correction method and apparatus. The apparatus includes at least one processor, and an input/output unit configured to receive an captured image, wherein the processor is configured to initialize a first matrix or a second matrix by reducing a matrix of a point spread function (PSF) of a lens included in a capturing device used to capture the captured image, iteratively perform an aberration removal and a noise removal based on the captured image and the first matrix or the second matrix, and output a final original image as a result of the iteratively performing. Here, the first matrix is a matrix obtained by reducing the number of indices indicating light arrival points of the matrix of the PSF, and the second matrix is a matrix obtained by reducing the number of indices corresponding to light arrival points of a transposed matrix of the PSF.

Abstract: Transmitting image data, and generating a three-dimensional (3D) image, may include generating one or more images associated with corresponding fields of view of one or more viewpoints that a display is configured to provide to a user, generating image data based on the images, and transmitting the image data to a target device. The one or more images may be generated based on weaving one or more images to generate one or more panel images. An image device that may receive the image data may generate one or more first images based on the image data, select one or more second images from the first images, and generate a panel image based on weaving the selected second images.
