7-4-3. PCS-C150/C150P Functions

CAM_WB
1) Auto white balance (AWB)
For this unit's AWB, the TTL method is adopted to reproduce the colors of the subject as closely as possible by calculating the color data
of the whole screen.
Furthermore, the white balance area is limited to prevent operations that show all objects as white from being performed when white
balance operations are performed.
The area for performing the auto white balance is also changed by determining whether it is indoors or outdoors according to the
brightness.
2) Preset white balance
The preset white balance can be selected from fixed indoors (3200K) and fixed outdoors (5800K).
3) One push white balance
The one push white balance is a function which, when once the subject is set to certain lighting conditions, will expose the subject under
these conditions by gaining white forcibly.
The color is reproduced naturally without being affected by the surrounding conditions of the subject.
When set, the one-push white balance trigger is sent assuming that the white subject occupies more than 1/2 of the screen.
The one-push white balance data is provided when the lithium backup SW is ON even though the power is off (2 hours for fully-charged
battery).When the lithium backup SW is off, the data will be lost when the power is turned off. Therefore, when turning off the power, set
the one-push white balance again.
