Abstract

See full text

Dynamic range enhancement methods and systems for display for use welding applications are described. A display system in a dynamic range enhancement system can include, for example, a splitter, a high density filter, a low density filter, a first image sensor, a second image sensor, a graphical circuit, and a display. The high density filter and the first image sensor can be disposed in a first path. The low density filter and the second image sensor can be disposed in a second path. The first image sensor can receive filtered electromagnetic waves from the high density filter. The second image sensor can receive filtered electromagnetic waves from the low density filter. The graphic circuit can combine the signals from the first image sensor and the second image sensor to provide a high dynamic range image or video that is displayed on the display of a welding helmet, for example.
