UNIFIED IMAGE PROCESSING FOR COMBINED IMAGES BASED ON SPATIALLY CO-LOCATED ZONES

摘要

A unified image processing algorithm results in better post-processing quality for combined images that are made up of multiple single-capture images. To ensure that each single-capture image is processed in the context of the entire combined image, the combined image is analyzed to determine portions of the image (referred to as “zones”) that should be processed with the same parameters for various image processing algorithms. These zones may be determined based on the content of the combined image. Alternatively, these zones may be determined based on the position of each single-capture image with respect to the entire combined image or the other single-capture images. Once zones and their corresponding image processing parameters are determined for the combined image, they are translated to corresponding zones each of the single-capture images. Finally, the image processing algorithms are applied to each of the single-capture images using the zone-specified parameters.

1. A method comprising:
accessing a plurality of images synchronously captured from by a multi-camera array; combining the plurality of images to form a combined image; determining a first plurality of zones for the combined image, each zone of the first plurality of zones encompassing a portion of the combined image, wherein no two zones of the first plurality of zones overlap; and for each of the plurality of zones, performing an image processing operation on all portions of the plurality of images corresponding to the zone.
