Realtime Auto White

The camera detects a white part in the image by itself, and its internal microcomputer
automatically adjusts white balance in realtime. Use this function in case that the color
temperature varies with time (e.g., from morning to day to night).

1.

In the MENU mode, set up WHITE BAL:AUTO.

(Note) If the color temperature of the scene being taken is changed abruptly (when the camera is

oriented from indoor side to outdoor side), the image may become bluish or reddish
momentarily. This phenomenon is not a symptom of trouble, however. Immediately
after it, the optimum white balance condition is set.

Where the camera is mounted fixedly and the orientation and image-taking range of the camera
remain unchanged. it is advisable to use the white gate function in combination for attaining
higher accuracy in white balance.

1.

In the MENU mode, set up WHITE GATE:ON.

2.

Using the WHITE GATE menu in the MENU mode, bring the display window to a monochrome
part (white or gray part) in the image.

For details of the WHITE GATE function, refer to p. 18. Be sure to set the WHITE GATE window
to a white or gray part in the image. Do not set it to a colored part.

Auto Shading Correction

Color shading may occur in the vertical direction on screen due to any characteristic of lens. This
camera is equipped with a function for correcting color shading automatically.

1.

Provide a proper aperture value of lens using the auto iris function or manually.

2.

Take an white image fully on screen. At this step, take care so that uneven brightness will not
occur in the vertical direction.

3.

In the DIRECT mode, press the AWB button. White balance is adjusted automatically.

4.

In the MENU mode, carry out AUTO SHADING. Thus, color shading in the image is corrected
automatically.

Note: Be sure to adjust auto shading when using the camera for the first time or after exchanging

the lens.

ＡＬＣ

In combination of GAIN:AGC, SHUTTER:AES, the following ALC (auto level control) can be

performed.
