Original Abstract Submitted
This disclosure describes techniques to concurrently capture several redundant (e.g., overlapping) video image streams on electronic devices having multiple image capture devices (e.g., on mobile devices having two or more digital video cameras). The techniques described herein advantageously capture at least one “compressed” video image stream, such that the overall multi-video image stream capture process uses significantly less power than capturing each stream independently in an “uncompressed” fashion. These techniques provide an electronic device with the ability to provide a user with more video streams that are of a higher frame rate and/or higher quality for a longer capture time-without exceeding the device's thermal limits. In particular, a “compressed” amount of image information may be processed and saved from at least one camera at capture time, and then deferred processing operations may be used to reconstruct any missing information and produce the higher frame rate/higher quality video image streams.
