Abstract: A system for power efficient image acquisition is configurable to capture, using an image sensor, a plurality of partial image frames including at least a first partial image frame and a second partial image frame. The first partial image frame is captured at a first timepoint using a first subset of image sensing pixels of the plurality of image sensing pixels of the image sensor. The second partial image frame is captured at a second timepoint using a second subset of image sensing pixels of the plurality of image sensing pixels of the image sensor. The second subset of image sensing pixels includes different image sensing pixels than the first subset of image sensing pixels, and the second timepoint is temporally subsequent to the first timepoint. The system is configurable to generate a composite image frame based on the plurality of partial image frames.

Abstract: A system and method for linking to accounts using credential-less authentication that includes: within a first application context at an account-linking computing service: receiving a request to establish an account link, establishing the account link to a user account of an account service using user credentials, and receiving user identifying information of the first application context and storing the user identifying information in association with the account link; and within a second application context at the account-linking computing service: receiving user identifying information of the second application context, searching and identifying a candidate account link using the user identifying information of the second application context, verifying eligibility for access to the account link, and permitting access to the account link upon successful verification of eligibility.
