Abstract: A method of determining an image capture timestamp offset or error includes generating optical flashes at an optical flash rate. A set of images of the optical flashes are captured at an image capture rate. The image capture rate is different from the optical flash rate, and each image includes an associated image timestamp. Signals associated with the generation of the optical flashes are also timestamped. The intensity of each image in the set of images is determined, and the image having the greatest intensity in the set of images is identified. The timestamp offset or error is determined as the difference between the timestamp of the image having the greatest intensity and the timestamp of the corresponding optical flash.

Abstract: Eyewear device including two system on a chip (SoC) that share processing workload. The SoCs communicate with each other using a low-power bridge, e.g., a mobile industry processor interface (MIPI) bridge including a display serial interface (DSI) to camera serial interface (CSI) bridge. The MIPI bridge converts DSI images from one SoC to CSI images, and also communicates metadata. Another SoC receives and processes the CSI images. The other SoC has a buffer that receives both the CSI images and the metadata, and separates the CSI images from the metadata. The other SoC has computer vision (CV) algorithms that process the metadata, and a low-speed interface that sends metadata back to the one SoC to adjust and render a next image. The MIPI bridge may comprise a field programmable gate array (FPGA).

Abstract: The invention relates to a method for generating and displaying a virtual object to an individual user by an optical system consisting of gaze-tracking glasses and at least one display unit connected to the gaze-tracking glasses, the display unit having a first display, the gaze-tracking glasses having a first eye-tracking camera, the first display being arranged in a first viewing region of the gaze-tracking glasses. According to the invention, the optical system is adapted to an individual user, a first target value for adaptation of a display control unit of the display unit for controlling the first display being determined, a current viewing direction of the first eye being determined by the gaze-tracking glasses, a virtual object being generated and, taking account of the first target value, the virtual object being displayed in the first display at a position in the determined viewing direction of the first eye.
