Title: HEAD-WORN DEVICE WITH CONTROL OF MEDIATED REALITY WELDING SYSTEM BASED ON LIGHTING CONDITIONS
Abstract:
An example head-worn device (20) includes a camera, a display device, weld detection circuitry, and pixel data processing circuitry. The camera generates first pixel data from a field of view of the head-worn device. The display device displays second pixel data to a wearer of the head-worn device based on the first pixel data captured by the camera. The weld detection circuitry determines whether a welding arc is present and generates a control signal indicating a result of the determination. The pixel data processing circuitry processes the first pixel data captured by the camera to generate the second pixel data for display on the display device, where a mode of operation of said pixel data processing circuitry is selected from a plurality of modes based on said control signal.
