1. An image processing system, comprising: a processor; memory containing a set of images captured from different viewpoints and an image processing pipeline application; wherein the image processing pipeline application configures the processor to: determine a range of distances corresponding to a restricted depth of field; generate a restricted depth of field depth map from the reference viewpoint using the set of images captured from different viewpoints, where the restricted depth of field depth map is generated by performing a disparity search that is performed using a greater density of depth samples within the range of distances corresponding to the restricted depth of field and a lower density of depth samples for distances outside the range of distances corresponding to the restricted depth of field; and render a restricted depth of field image from the reference viewpoint using the set of images captured from different viewpoints and the restricted depth of field depth map.
