Functions and set values

Initial value

 

 

 

V PHASE

This adjusts the vertical synchronization to those of other cameras

0

 

when a selector switch for the synchronizing system on the side

 

 

is at LL. (50Hz power region only.)

 

 

When it is not set to LL, “---” will appear, disabling change

 

 

the set value.

 

 

[Set value: –156 to 0 to 156]

 

 

 

 

H PHASE

This adjusts the horizontal synchronization to those of other

0

 

cameras and systems when a selector switch for the

 

 

synchronizing system on the side is at INT/GL.

 

 

When external signals are not input, “---” will appear, disabling

 

 

change the set value.

 

 

[Set values: –16 to 0 to 16]

 

 

 

 

SC COARSE

Coarse adjustment of the SC phase in gen-lock operation.

0°

 

The SC phase can be varied by up to 90° in each direction.

 

 

Adjust with reference to another camera (or system) and

 

 

together with the SC FINE adjustment.

 

 

Adjust SC COARSE and SC FINE only after adjusting H

 

 

PHASE.

 

 

When it is not set to GL, “---” will appear, disabling change

 

 

the set value.

 

 

[Set values: 0°, 90°, 180°, 270°]

Functions and set values

Initial value

 

 

 

IRIS LEVEL

Adjusts the brightness level of the video signal.

NORMAL

 

• To lower the brightness level ... Decrease the value

 

 

• To raise the brightness level .... Increase the value

 

 

[Set values: –5 to NORMAL to 5]

 

 

 

 

AVERAGE:

Sets the exposure detection as a ratio of the average value

8 : 2

PEAK

and the peak value.

 

 

• AVERAGE value large: Increase the AVERAGE value

 

 

when portions other than the highlighted areas of the

 

 

screen are dark and look corrupted. (Ex. 10:0)

 

 

• PEAK value large: Increase the PEAK value when

 

 

halation occurs in the highlighted areas of the screen.

 

 

(Ex. 5:5)

 

 

[Set values: 10:0, 9:1, 8:2, 7:3, 6:4, 5:5]

Functions and set values

Initial value

SHUTTER

This sets the electronic shutter as well as the ExDR (Extended

NORMAL

/ExDR

Dynamic Range).

 

 

The use of an electronic shutter function enables shooting with

 

 

proper brightness, as more brightness results in higher shutter

 

 

speed.

 

 

 

The ExDR function allows even the shooting of a subject having

 

 

different luminous flux density by composing a picture shot at 1/

 

 

100 sec. shutter speed with a picture shot by a high-speed

 

 

shutter.

 

 

 

NORMAL: This fixes the shutter speed to 1/50.

 

 

 

The ExDR does not function.

 

 

MANUAL: This sets the shutter speed by the item SHUTTER

 

 

 

SPEED on the SHUTTER screen.

 

 

 

The ExDR does not function.

 

 

 

When SENSE UP is functioning, MANUAL cannot be

 

 

 

selected. (Not displayed on MENU)

 

 

AUTO:

This automatically switches the shutter speed

 

 

 

according to brightness.

 

 

 

The ExDR does not function.

 

 

 

The item FAST LIMIT on the SHUTTER (ExDR) screen

 

 

 

sets a maximum shutter speed value.

 

 

M.ExDR:

This is used when shooting a subject with difference

 

 

 

in a luminous flux density in the screen under a fixed

 

 

 

illumination condition, and so on. During ExDR mode,

 

 

 

the item M.ExDR.SPEED on the SHUTTER (ExDR)

 

 

 

screen sets the composing high shutter speed. It is

 

 

 

possible to set only when the items BLC and SENSE

 

 

 

UP are OFF. What’s more, the ExDR LEVEL sets the

 

 

 

signal level of the composing high-speed shutter.

 

 

A.ExDR:

This is used when the subjects having different

 

 

 

luminous flux densities are continuously used night

 

 

 

and day in the situation where both indoor and outdoor

 

 

 

subjects are mixed in existence, and so forth. During

 

 

 

ExDR mode, the composing shutter speed

 

 

 

automatically varies according to the contrast of a

 

 

 

subject. This is set when shooting the subject with

 

 

 

changing brightness.

 

 

 

This can be set only when the item BLC is OFF.

 

 

 

What’s more, the ExDR LEVEL sets the signal level

 

 

 

of the composing high-speed shutter.

 

MEMO

Do not set to A.ExDR when using a manual lens.

When M.ExDR mode or A.ExDR mode is used, the border between a bright part and a dark part can be coloured (cyan, orange, etc.), but this is not a malfunction.

When the SHUTTER/ExDR item is set to M.ExDR or A.ExDR, a flicker can occur under a fluorescent lamp, mercury lamp, etc. However, this occurs by principle of the ExDR function, and therefore this is not a malfunction.

* When the SHUTTER (ExDR) item is set to NORMAL, the following items (SHUTTER SPEED, FAST LIMIT, ExDR LEVEL, and M.ExDR SPEED) cannot be changed.

 

SHUTTER

This sets a shutter speed when MANUAL is set.

1/120

 

SPEED

The AUTO, M. ExDR, A. ExDR set value is displayed as

 

 

 

“- - -” and cannot be changed

 

 

 

[Set values: 1/120, 1/250, 1/500, 1/1000, 1/2000, 1/4000, and 1/
