Abstract: In one embodiment, methods, media, and systems process and display light field images using a view function that is based on pixel locations in the image and on the viewer's distance (observer's Z position) from the display. The view function can be an angular view function that specifies different angular views for different pixels in the light field image based on the inputs that can include: the x or y pixel location in the image, the viewer's distance from the display, and the viewer's angle relative to the display. In one embodiment, light field metadata, such as angular range metadata and/or angular offset metadata can be used to process and display the image. In one embodiment, color volume mapping metadata can be used to adjust color volume mapping based on the determined angular views; and the color volume mapping metadata can also be adjusted based on angular offset metadata.

Abstract: A light field camera system and method of setting a baseline and a convergence distance of a multiple camera rig employ sample point depths to determine and set values with respect to a three-dimensional (3D) scene. A baseline and a convergence distance of a multiple camera rig is set by determining a plurality of sample point depths representing distances between the multiple camera rig and a plurality of sample points in the 3D scene within a field of view of the multiple camera rig. The convergence distance is set to be an average sample point depth of the plurality of sample point depths. The baseline is then set as a negative inverse of a difference between a minimum sample point depth of the plurality of sample point depths and the convergence distance. The light field camera system includes a multiple camera rig comprising a plurality of cameras.
