(Weight balance) adjustment will be described. Generally, in a video camera, it is necessary to perform WB adjustment.
Although it is necessary, with conventional cameras, auto WB, one touch
WB and preset WB can be adjusted. The automatic WB adjustment is performed based on the input image signal.
In order to obtain a proper WB,
Automatically sets 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 is changed to white.
So that it is not always recorded with a good color tone.
Not always. 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.
