When the Bracketing mode is configured, an exposure time setting applies to Stream #1, and
the
Auto exposure bracketing
Stream #2. The configurable Level ratio is inversely proportional to the Exposure time setting
above, namely 5x = 1/5 of the Exposure time above. If the level is configured as 5x, the Stream
#2 exposure time will be 1/5 of that of Stream #1.
The other benefits 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.
