Intelligent functions
When using the camera in outdoor environments, the brightness and color temperature will
differ significantly as the day progresses from the morning to the afternoon, to the evening
to night. The camera’s intelligent functions serve to automatically correct the video level
and color temperature to compensate for the changes taking place outdoors.
In outdoor environments, the brightness changes significantly, by a factor of 10 to the
power of 6, from 0.01 lux under a crescent moon to 10,000 lux under a clear sky.
Similarly, there is a considerable change of 5000K in the color temperature from 000K
after sunrise to 8000K under a clear, bright sky.
In the past, the gain, lens iris, ND filter, and minus gain were supported as video levels
adjustments, whereas manual gain adjustments and manual CC filter settings were
supported as color temperature adjustments.
However, the problem with the user having to make these adjustments manually each
time was that there was not enough time to select the optimum adjustments when a
sudden emergency situation such as an earthquake arose, with the result that shooting
opportunities were lost.
Now, using the intelligent functions, this kind of problem has been solved.
