Setting Camera Performance
If you need to adjust the sensitivity in dark places (AGC*), follow
steps below.
■
NORM
Normal setting
■
HIGH (For a dark subject)
Setting with which a bright image is obtained in a lower illuminance
than the NORM setting.
• This setting causes noise generation and a grainy image.
■
OFF
Fixed gain setting
Change the mode for Gamma correction*.
■
0.45: Gamma value of
γ
= 0.45
■
1: Gamma value of
γ
= 1
■
OFF
No accentuating is performed for aperture.
■
NORM
Normal setting
■
HIGH
Setting with which the outline becomes crisper than the NORM
setting.
■
HIpls (High plus)
Setting with which the outline becomes crisper than the HIGH
setting.
E Setting Gain Value <AGC GAIN>
F Correcting Gamma Characteristic <GAMMA>
* AGC (Auto Gain Control) is a function to adjust automatically the
gain of the video signal from the camera so that an optimum signal
level is obtained according to brightness of the object.
* About Gamma correction
Gamma (
γ
) is a value representing a responsiveness characteristic of
image contrast. Every input and output device of image data has its
own Gamma value; the overall Gamma value must be corrected to be
equal to 1. If a CRT monitor has a Gamma value of 2.2, for example,
the value for this unit must be corrected to 0.45 (2.2 x 0.45
≈
1).
G Specifying Shutter Speed <SHUTTER>
• Select from: 60, 100, 250, 500, 1000, 2000, 4000, and 10000
(e.g., 60 refers to 1/60 second)
Note: With the increase in shutter speed number, faster movement can
be captured, though the image becomes darker.
H Accentuating Subject Outline <APERTURE>
* Aperture means outline correction. The more the outline is
highlighted, the higher the apparent resolution looks.
