Abstract: Devices and methods for dynamic power configuration (e.g., reduction) for thermal management (e.g., mitigation) in a wearable electronic device such as an eyewear device. The wearable electronic device monitors its temperature and, responsive to the temperature, configures the services it provides to operate in different modes for thermal mitigation (e.g., to prevent overheating). For example, based on temperature, the wearable electronic device adjusts sensors (e.g., turns cameras on or off, changes the sampling rate, or a combination thereof) and adjusts display components (e.g., adjusted rate at which a graphical processing unit generates images and a visual display is updated). This enables the wearable electronic device to consume less power when temperatures are too high in order to provide thermal mitigation.

Abstract: Systems and methods herein describe pausing operation of an augmented reality device based on user facial movement by monitoring user eye movement of a user of a head-wearable apparatus, determining that the user eye movement is directionally facing away from a display device coupled to the head-wearable apparatus, based on the determination, pausing operation of one or more sensors of the head-wearable apparatus.

Abstract: An electronic eyewear device includes first and second systems on a chip (SoCs) having independent time bases that are synchronized by generating a common clock signal from a clock generator of the first SoC and simultaneously applying the common clock signal to a first counter of the first SoC and a second counter of the second SoC whereby the first counter and the second counter count clock edges of the common clock. The clock counts are shared through an interface between the first SoC and the second SoC and compared to each other. When the clock counts are different, a clock count of the first counter or the second counter is adjusted to cause the clock counts to match each other. The adjusted clock count is synchronized to the respective clocks of the first and second SoCs, thus synchronizing the first and second SoCs to each other.

Abstract: Imaging methods and imagers for image capture devices. Still images are captured by gathering ambient light data using an ambient light sensor of the image capture device, selecting a frame rate for the imager corresponding to the gathered ambient light data, determining optimal image capture parameters for the imager by executing an auto exposure algorithm with a processor using the selected frame rate as an initialization parameter for the auto exposure algorithm, and capturing a still image with the imager after execution of the auto exposure algorithm using the selected frame rate.

Abstract: Camera compensation methods and systems that compensate for misalignment of sensors/camera in stereoscopic camera systems. The compensation includes identifying a pitch angle offset between a first camera and a second camera, determining misalignment of the first and second cameras from the identified pitch angle offset, determining a relative compensation delay responsive to the determined misalignment, introducing the relative compensation delay to image streams produced by the cameras, and producing a stereoscopic image on a display from the first and second image streams with the introduced delay.

Abstract: Eyewear having an image signal processor (ISP) dynamically operable in a camera pipeline for augmented reality (AR) and computer vision (CV) systems. Multi-purpose cameras are used for simultaneous image capture and CV on wearable AR devices. The cameras are coupled to a frame and configured to generate images, wherein the cameras and the ISP operate in a first AR mode and capture images having a first resolution suitable for use in AR, and are configured to operate in a second CV mode to provide the images having a second resolution suitable for use in CV. The first resolution in the AR mode is higher than the second resolution in the CV mode, and the cameras and the ISP consume less power in the second CV mode than the first AR mode. The cameras and the ISP save significant system power by operating in the low power mode CV mode.
