Light Field Camera Array. This technique captures light field successfully from a sparse camera array with no mask or any other optical modifications on cameras. Of course, a large camera array makes portability a challenge in addition to the heavy computing power required to generate the final light field image from the vast amounts of data collected by each camera in the array.

Another important feature is that the light field can be used to calculate exact positions in the images. A global energy minimization based on belief propagation is proposed to regularize the results. The next step in light field imaging development that solved the portability challenge was the invention of the plenoptic camera.

The light field is a 4d function that represents the radiance of light traveling in every direction through every point in 3d space. Figure 3c compares the performance of various array cameras, including the aware2 camera 3, virtual reality cameras 20,21, light field camera 6,15, and our array camera. The light field technology also has an advantageous effect in factory halls where no active lighting is desired, since the light field is very robust.
