Abstract:
Dynamic range enhancement methods and systems for display for use welding applications are disclosed. An example display system in a dynamic range enhancement system includes: a first filter disposed in a first path; a second filter disposed in a second path, wherein the second filter has a lower density than the first filter, at least one of the first filter or the second filter configured to provide variable lens shading; a first image sensor disposed in the first path and configured to receive filtered electromagnetic waves from the first filter; a second image sensor disposed in the second path and configured to receive filtered electromagnetic waves from the second filter; and a graphical circuit configured to combine signals from the first image sensor and the second image sensor.
