HDR Pipeline

HDR imaging is a revolution in the field of imaging permitting the ability to use and manipulate physically real light values. This chapter introduces the main processes of HDR imaging, which can be best characterized as a pipeline, termed the HDR pipeline. Figure 2.1 illustrates the distinct stages of the HDR pipeline.

Figure 2.1. The HDR pipeline in all its stages. Multiple exposure images are captured and combined, obtaining an HDR image. Then this image is quantized, compressed, and stored. Further processing can be applied to the image. For example, areas of high luminance can be extracted and used to relight a synthetic ...
