Abstract: Techniques for rectification of camera arrays are described. In one embodiment, for example, an apparatus may comprise a processor circuit and an imaging management module, and the imaging management module may be operable on the processor circuit to determine a composite rotation matrix for a camera array comprising a plurality of cameras, determine a composite intrinsic parameter matrix for the camera array, and compute one or more rectification maps for the camera array based on the composite rotation matrix and the composite intrinsic parameter matrix, each of the one or more rectification maps corresponding to one of the plurality of cameras. Other embodiments are described and claimed.

Abstract: Techniques for improved focusing of camera arrays are described. In one embodiment, for example, an apparatus may comprise a processor circuit and an imaging management module, and the imaging management module may be operable by the processor circuit to determine, for each of a plurality of candidate displacement factors for an image array comprising a plurality of images, a corresponding sharpness, determine an optimal displacement factor comprising a candidate displacement factor corresponding to a maximized sharpness, and transform the image array based on the optimal displacement factor. Other embodiments are described and claimed.
