Abstract: Systems and techniques are described for performing foveated sensing. In some aspects, a method (e.g., implemented by an image sensor) can include capturing sensor data for a frame associated with a scene, obtaining information corresponding to a region of interest (ROI) associated with the scene, generating a first portion (having a first resolution) of the frame corresponding to the ROI, generating a second portion of the frame having a second resolution, and outputting (e.g., to an image signal processor (ISP)) the first portion and the second portion. In some aspects, a method (e.g., implemented by an ISP) can receive, from an image sensor, sensor data for a frame associated with a scene, generating a first version (having a first resolution) of the frame based on an ROI associated with the scene, and generating a second version of the frame having a second resolution (lower than the first resolution).

Abstract: In some aspects, the present disclosure provides a method for managing a command queue in a universal flash storage (UFS) host device. The method includes determining to power on a first subsystem of a system-on-a-chip (SoC), wherein the determination to power on the first subsystem is made by a second subsystem of the SoC based on detection of user identity data contained in a first image frame during an initial biometric detection process. In certain aspects, the second subsystem is configured to operate independent of the first subsystem and control power to the first subsystem. In certain aspects, the second subsystem includes a second optical sensor, a set of ambient sensors, and a second processor configured to detect, via a set of ambient sensors, an event comprising one or more of an environmental event outside of the device or a motion event of the device.

Abstract: In some aspects, the present disclosure provides a method for sharing a single optical sensor between multiple image processors. In some embodiments, the method includes receiving, at a control arbiter, a first desired configuration of a first one or more desired configurations for capturing an image frame by the optical sensor, the first one or more desired configurations communicated from a primary image processor. The method may also include receiving, at the control arbiter, a second desired configuration of a second one or more desired configurations for capturing the image frame by the optical sensor, the second one or more desired configurations communicated from a secondary image processor. The method may also include determining, by the control arbiter, an actual configuration for capturing the image frame by the optical sensor, the actual configuration based on the first desired configuration and the second desired configuration.
