Abstract: High dynamic range images are generated using conventional dynamic range cameras. A first camera is configured with exposure settings that are optimized for brighter regions, while a second camera assembly is optimized for darker regions. The cameras can be rectified and can capture concurrently such that objects are relatively aligned, with global and local misregistrations being minimized. The image data is analyzed to determine regions where the image data from one camera or the other provides higher quality, such as where the brightness values fall between a noise floor and a saturation level. If image data from both sets have values within that range then the values can be combined, such as with a weighted average. A composite image is generated that includes more uniform color and brightness than in either image individually, or that could have been captured using a single camera of similar cost and capabilities.
