An image processing apparatus is disclosed. The image processing apparatus comprises: a receiver configured to receive an input frame including a plurality of image regions, corresponding to a plurality of faces of a three-dimensional polyhedron, and metadata; and a processor configured to render an output frame including at least one a part of the input frame, on the basis of padding information included in the metadata. Here, the processor may be configured to identify, on the basis of the padding information, a padding region included in at least one of the plurality of image regions, and render, on the basis of the determined padding region, a boundary between at least one face of the plurality of faces and another face of the plurality of faces adjoining the at least one face of the polyhedron.

Method for processing omni-directional image using padding area and apparatus supporting the same

A method for operating an electronic device for rendering an augmented reality object is provided. The method includes obtaining at least one first image of an environment in which an augmented reality virtual object is to be displayed, obtaining an environment texture based on the obtained at least one first image, identifying at least one light source in at least one second image by identifying at least one cluster comprising pixels with a brightness value greater than a threshold, determining a position of the at least one light source based on a position of the pixels within the at least one cluster, rendering the augmented reality virtual object based on the obtained environment texture and the determined position of the at least one light source, and displaying the rendered augmented reality virtual object on a display of the electronic device.

Method for estimating light for augmented reality and electronic device thereof

A method includes: dividing the 3D virtual scene by using a plurality of grids; acquiring location information about a plurality of first points at which a plurality of rays originating from a light source are incident on one or more objects located within the 3D virtual scene and location information about a plurality of first grids including the plurality of first points; acquiring location information about a plurality of second points at which the plurality of rays reflected from the plurality of first points are incident on the one or more objects and location information about a plurality of second grids including the plurality of second points; and determining illumination of each of the plurality of grids based on the location information about the plurality of first grids and the location information about the plurality of second grids.
