Image processing apparatus and method therefor

摘要

A first surface, a second surface, and a third surface are set in order in a direction of a scene, and the first surface has a plurality of cells and a plurality of sub-cells divided from each of the plurality of cells, the second surface has a plurality of segments, and the plurality of cells and the plurality of segments are associated respectively. A trace direction of a ray passing through each sub-cell is determined based on a segment associated with a cell including the sub-cell. Ray tracing on the determined trace direction is performed for each sub-cell so as to generate light-field data of the scene between the second and third surfaces.

主权项

1. An image processing apparatus for generating light-field data of a scene using a ray tracing method, comprising:
one or more hardware processors; and a memory coupled to the one or more hardware processors and storing instructions that, when executed by the one or more hardware processors, cause the image processing apparatus to:
set a first surface, a second surface, and a third surface in order in a direction of a scene, wherein the first surface has a plurality of cells and a plurality of sub-cells divided from each of the plurality of cells, the second surface has a plurality of segments, and the plurality of cells and the plurality of segments are associated respectively;determine a trace direction of a ray passing through each sub-cell based on a segment associated with a cell including the sub-cell; andperform ray tracing on the determined trace direction for each sub-cell so as to generate light-field data of the scene between the second and third surfaces.
