Stream1 = 1/1600
Stream2 = 1/5 x 1/1600
When the Bracketing mode is congured, an exposure time setting applies to Stream #1, and
the Auto exposure bracketing level will be used to determine the short exposure time taken by
Stream #2. The congurable Level ratio is inversely proportional to the Exposure time setting
above, namely 5x = 1/5 of the Exposure time above. If the level is congured as 5x, the Stream
#2 exposure time will be 1/5 of that of Stream #1.
The other benets of the Bracketing mode can be:
1. Supports a wider dynamic range.
2. Better chance of producing a clear image when objects appear with low contrast under bad
lighting conditions. Setting a very large Auto exposure bracketing level can result in a very
short shutter time. As the result, image quality can degrade in a low-contrast scenario.
