| Scenes with highly varying lighting conditions and significant spatial depth cause problem in imaging that not all the information contained in these scenes could be captured by one image.
| | test |
| | |
| Dynamic range of a scene is defined as the ratio of the highest to the lowest luminance. The real world scenes often have a very wide range of luminance ( Fig. 1 ), sometimes exceeding 10 orders of magnitude. To reproduce these scenes presents a challenge for conventional digital capture and display devices, which suffer a limited dynamic range of only 2 orders of magnitude. Radiance maps [1, 2],
| |
| obtained by merging a sequence of low dynamic range
| |
| ( LDR ) images of the same scene taken under different
| |
| exposure intervals ( Fig. 1 ), are able to record the full
| |
| dynamic range of the scene in 32-bit floating-point number
| |
| format. However, LDR reproduction media such as CRT
| |
| monitors and printers are usually only 8-bit per channel.
| |
| Tone Mapping or Tone Reproduction is the process to
| |
| compress the dynamic range of the radiance maps to fit into
| |
| that of the display devices, while preserving as much of
| |
| visibility and visual contrast as possible.
