Abstract

According to various embodiments of the present invention, the optical systems of light field capture devices are optimized so as to improve captured light field image data. Optimizing optical systems of light field capture devices can result in captured light field image data (both still and video) that is cheaper and/or easier to process. Optical systems can be optimized to yield improved quality or resolution when using cheaper processing approaches whose computational costs fit within various processing and/or resource constraints. As such, the optical systems of light field cameras can be optimized to reduce size and/or cost and/or increase the quality of such optical systems.

First claim

What is claimed is:

1. In a light field image capture device, the light field image capture device including at least one sensor and processing circuitry, the processing circuitry configured to process captured light field image data to generate visual output, a method for reducing the size of captured light field image data, the method comprising:
capturing light field image data at the at least one sensor, the light field image data representing output of a microlens array;
de…
