Multi-processor support for array imagers
Using the techniques discussed herein, a set of images is captured by one or more array imagers ( 106 ). Each array imager includes multiple imagers configured in various manners. Each array imager captures multiple images of substantially a same scene at substantially a same time. The images captured by each array image are encoded by multiple processors ( 112, 114 ). Each processor can encode sets of images captured by a different array imager, or each processor can encode different sets of images captured by the same array imager. The encoding of the images is performed using various image-compression techniques so that the information that results from the encoding is smaller, in terms of storage size, than the uncompressed images.
1. A smartphone, comprising:
at least one non-transitory computer-readable media to store instructions;
at least one processor;
a display; and
at least one array imager including a plurality of first imagers and at least one second imager,
wherein
at least one of the first imagers and the at least one second imager are operable to capture a first set of images and a second set of images, the first set of images including a first plurality of images that depict substantially a same scene at substantially a same time and the second set of images including a second plurality of images that depict substantially a same scene at substantially a same time, and
the at least one processor includes a single processor with two or more distinct cores configured to execute the instructions to:
obtain the first set of images and the second set of images,
encode, using one of the two or more distinct cores, the first set of images, and
encode, using another of the two or more distinct cores, the second set of images.
