WB and preset WB can be adjusted. The automatic WB adjustment is performed based on the input image signal.
In order to obtain the proper WB, the camera shown in FIG.
Automatically set the position of the WB correction center on the color vector plane.
It is an adjustment to determine. The disadvantage of this adjustment is that the overall color
When a color is biased toward a certain color, the color becomes white.
So that it is not always recorded with a good color tone.
Not always. Further, the one-touch WB adjustment is performed for a pure white image.
Captures body image signals and recognizes them as white
Adjust as follows. This adjustment allows you to carry a pure white
And it is not easy to use. The preset WB adjustment is performed during WB correction.
As heart value data, multiple color temperatures representative of the system
Memorize the values and adjust them according to the condition of the subject, such as sunny or cloudy.
To select the above color temperature value. For example, the color of FIG.
