1. A system comprising: a camera configured to generate first pixel data from a field of view of a welding headwear; a display device to display second pixel data to a wearer of the welding headwear based on the pixel data captured by the camera; weld detection circuitry configured to: determine whether a welding arc is present based on an intensity of light incident captured by said light intensity detection circuitry; and generate a control signal indicating a result of said determination; and pixel data processing circuitry configured to process the first pixel data captured by the camera to generate the second pixel data for display on the display device, wherein a mode of operation of said pixel data processing circuitry is selected from a plurality of modes based on said control signal.
