Abstract:
1. A time-of-flight image sensor comprising: a plurality of time-of-flight sensor pixels, each time-of-flight sensor pixel being configured to generate at least one charge; a first frame storage circuit having a first set of charge storage devices, the first frame storage circuit being operatively coupled to the plurality of time-of-flight sensor pixels and configured to: a second frame storage circuit having a second set of charge storage devices, the second frame storage circuit being operatively coupled to the first frame storage circuit and configured to receive, at the second time from the first frame storage circuit, the first set of charges and to store the first set of charges in the second set of charge storage devices, wherein the first frame storage circuit and the second frame storage circuits are configured to output analog signal charge contents of the first and second frame storage circuits in parallel to one another for use by a processing device, wherein each time-of-flight sensor pixel further comprises at least two photosites that are configured to generate a charge pair having a charge generated by each photosite of two different time segments, and wherein the first set of charges generated by the plurality of time-of-flight sensor pixels further comprises the charge pairs.
