Abstract: A system comprises light intensity detection circuitry and pixel data processing circuitry. The light intensity detection circuitry is operable to determine whether a welding arc is present based on an intensity of light incident captured by the light intensity detection circuitry, and generate a control signal indicating a result of the determination. A mode of operation of the image processing circuitry may be selected from a plurality of modes based on the control signal. The light intensity detection circuitry may comprise, for example, a passive infrared sensor, a photodiode, and/or circuitry of a camera. The pixel data processing circuitry may comprise, for example, circuitry of a camera, a special purpose graphics processing unit, and/or a general purpose processing unit.
