Adjusting the Exposure
Compensate the exposure to adjust the brightness while checking the live image.
How to read the level meter
The [LEVEL] meter of [CAM MENU] shows the exposure
condition.
There are 12 indicators; four in the center are green, four on the
right are red, and four on the left are blue. The exposure condition
is indicated by the position of indicators being lit up.
Four indicators are always lit, and the four in the center (green)
are lit up during proper exposure.
The position of lit up indicators moves to the right as the exposure
becomes high, and to the left as it becomes low. To change the
setting, operate again from the [EXP CMP] button.

Checking the Histogram of the Image
When you press the [HISTOGRAM] button on the task bar, the
[HISTOGRAM] window appears at the right bottom of the screen.
On the [HISTOGRAM] menu, the system calculates the
distribution of brightness of the image and shows it as a
histogram.
The histogram indicates distribution of brightness for each RGB
color which allows fine adjustment of the exposure level.
•
The horizontal axis indicates brightness (dark to light from left
to right).
•
The vertical axis indicates appearance frequency.
•
On the right to the histogram, average values of RGB colors
are shown.

Reading and compensating the exposure
When the distribution reaches the right end of the histogram, the bright part of the image is saturated (white-out).
When the distribution reaches the left end of the histogram, the dark part of the image is collapsed (black-out).
It is preferred that no white-out and black-out occurs in the entire image, but, in some cases, adjustment is
necessary.
If a bright part of the image is important, adjust the distribution to the left. If a dark part is important, adjust the
distribution to the right.
By adjusting the distribution in accordance with the important level, it is possible to prevent insufficient gradation
during image processing.
