Abstract: A method performed by an electronic device is described. The method includes obtaining an input image. The input image includes image noise. The method also includes removing the image noise from the input image to produce a noise-removed image. The method further includes avoiding enhancing the image noise by performing edge detection on the noise-removed image to produce edge information. The method additionally includes producing a processed image based on the input image and the edge information.

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.

Abstract: Methods, systems, and devices for image processing are described. A device may include a plurality of buffer components, each of which may receive a pixel lines that may each be associated with a respective raw image. An arbitration component of the device may combine at least some of the pixel lines into one or more data packets. The arbitration component may pass, using an arbitration scheme such as a time division multiplexing scheme, the one or more data packets from the arbitration component to a shared image signal processor (ISP) of the device. The shared ISP may generate a respective processed image based at least in part on the one or more data packets. In some examples, the device may maintain a respective set of image statistics, registers, and the like for at least some of the raw images.
