Systems and methods for implementing array camera configurations that include a plurality of constituent array cameras, where each constituent array camera provides a distinct field of view and/or a distinct viewing direction, are described. In several embodiments, image data captured by the constituent array cameras is used to synthesize multiple images that are subsequently blended. In a number of embodiments, the blended images include a foveated region. In certain embodiments, the blended images possess a wider field of view than the fields of view of the multiple images.
