LENS ADJUSTMENT
Video adjust
A readjustment might be necessary depending on the configuration of the shooting object or the
lens installed. To perform a readjustment, the AGC switch on the back of the unit should be turned
OFF before adjusting the LEVEL. Turn the AGC on again when the adjustment has been completed.
• LEVEL adjustment
Monitor screen
Too bright
Too dark
• If the sensitivity adjustment LEVEL is turned too far to L, the sensitivity will increase due to the
AGC function of the camera, making the image look grainy.
Back focus adjustment
Back focus has been optimally adjusted at the factory for CS-mount lenses, but it may
need re-adjustment if the mount is changed for C-mount lenses. If required, adjust as
follows:
• With a fixed-focus lens
If the focus can not be adjusted correctly by rotating the lens focus ring, adjust the back focus as
follows.
1. Loosen the back focus locking screw by turning it anti-clockwise (
2. Point the camera at a test pattern.
3. Turn the lens focus ring to '.
4. Turn the back focus adjustment ring to find optimum focus.
5. Tighten the back focus locking screw by turning it clockwise (
• With a zoom lens
If the lens does not track (loses focus) at any point in the zoom range, adjust as follows:
1. Loosen the back focus locking screw by turning it anti-clockwise (
2. Point the camera at a comparatively dark scene with thin lines.
3. Set the lens to the maximum telephoto position, and adjust the lens focus.
4. Set the lens to the maximum wide-angle position, and turn the back focus ring to adjust the
focus.
(Repeat steps 2 and 3 two or three times.)
5. Tighten the back focus locking screw by turning it clockwise (
SETTING SWITCH
(The illustration shows the factory-set default settings.)
Line Lock
To set the camera in LL mode for synchronization with the power supply frequency, do the following :
1. Turn switch
to "LL";
2. Press the + or – button
to make the phase variable.
Adjust with the button
so that the vertical phase of the camera matches the vertical phase of
another camera (or system) with a multi-channel oscilloscope.
To reset the setting, press the + and – buttons
U type
: 60Hz power region only
E/EG type : 50Hz power region only
White Balance
White balance can be adjusted within the scope of 2300 K to 10000 K color temperature. When
switch
is at ATW (Auto-Tracking White Balance), the white balance is automatically adjusted
according to the color temperature of the ambient illumination.
When the white balance is set to AWB (Auto White Balance), press and hold the SET button
2 seconds to adjust or readjust the white balance. Once the white balance is adjusted, the setting
will not track changes in the color temperature of the ambient illumination.
BLC (Back Light Compensation)
The switch
helps to rectify the situation where a subject appears dark because of backlighting.
Set this switch to ON for strongly backlit subjects.
AES (Automatic Electronic Shutter)
Turning this switch
"ON" when a lens with a manual iris diaphragm is used enables the automatic
adjustment of image brightness. In this case the shutter speed changes according to the bright-
ness of the subject.
Hunting may occur at a certain object brightness due to the mechanism of the AES circuit, but
this is not a fault.
AGC (Automatic Gain Control)
The switch
automatically increases the camera's sensitivity when the level of ambient light drops.
ON: AGC is activated.
OFF: AGC is not activated.
