Methods and apparatus for full-resolution light-field capture and rendering

A system, comprising:

• at least one processor;
• and
• a memory comprising program instructions, wherein the program instructions are executable by the at least one processor to:
• obtain a flat comprising a plurality of separate portions of an image of a scene, wherein each of the plurality of separate portions is in a separate region of the flat, wherein each of the plurality of separate portions comprises a plurality of pixels, and wherein the flat is a 2D representation of a 4D light-field that captures both spatial and angular information of the scene;
• crop each of the plurality of separate portions to an m1×m2 pixel subregion of the respective portion to generate a plurality of m1×m2 pixel subregions from the plurality of separate portions, where at least one of m1 and m2 is an integer greater than or equal to two;
• and
• assemble the plurality of subregions to produce a single image of the scene.

A non-transitory computer-readable storage medium storing program instructions, wherein the program instructions are computer-executable to implement:

• obtaining a flat comprising a plurality of separate portions of an image of a scene, wherein each of the plurality of separate portions is in a separate region of the flat, wherein each of the plurality of separate portions comprises a plurality of pixels, and wherein the flat is a 2D representation of a 4D light-field that captures both spatial and angular information of the scene;
• generating a plurality of m1×m2 pixel subregions from the plurality of separate portions, wherein said generating comprises cropping each of the plurality of separate portions to an m1×m2 pixel subregion of the respective portion, where at least one of m1 and m2 is an integer greater than or equal to two;
• and
• assembling the plurality of subregions to produce a single high-resolution image of the scene.

A non-transitory computer-readable storage medium storing program instructions, wherein the program instructions are computer-executable to implement:

• obtaining a flat comprising a plurality of separate portions of an image of a scene, wherein each of the plurality of separate portions is in a separate region of the flat, wherein each of the plurality of separate portions comprises a plurality of pixels, and wherein the flat is a 2D representation of a 4D light-field that captures both spatial and angular information of the scene;
• examining each of two or more of the plurality of separate portions to determine a direction of movement of edges within the two or more separate portions, wherein said examining is performed in a direction, and wherein an edge is a feature of the image of the scene that appears in one or more of the portions;
• detecting that the direction of movement of edges in the two or more separate portions is the same as the direction in which said examining is performed;
• inverting at least the two or more separate portions relative to their respective centers in response to said detecting;
• and
• assembling the plurality of separate portions to produce a single high-resolution image of the scene.
