Abstract
Aspects of the present disclosure describe systems, methods, and structures for improved compression of array camera image data and improved power budgets for array cameras.
Claims6
A code division compression method for an array camera system including a plurality of individual micro-cameras that produce a plurality of individual data streams, each individual data stream being produced by a different individual micro-camera and representing its respective individual micro-camera's individual field-of-view, said method CHARACTERIZED BY:
- multiplexing the plurality of individual data streams using a code-division-multiple-access (CDMA) technique to produce compressed multiplexed image data, wherein the cdma technique is a remote region code division multiple access technique wherein a coded signal defined by the following is produced:
- qijk=Summ(xijkm cijkm), wherein xijkm is a pixel value and cijkm is a code value, each corresponding to an ijth spatial pixel at a time k for an mth micro-camera;
- and cijkm is drawn from +1 and −1;
- and
- analyzing the compressed multiplexed image data to identify at least one part of the image data stream for decompression.
