MEMO

When “ExDR” is set to other than “ON”, this item will be displayed as “---” and setting will be

disabled.

ExDR MODE

The ExDR function synthesizes pictures captured at a shutter speed of 1/100 and

OFF

those captured at higher shutter speeds to help monitor objects having large differ-

ences in brightness levels.

When the “SHUTTER” function is set to “1/250” or a higher, this function does not

work and “---” is displayed as the item name in the CAMERA ALC Screen.

OFF : Turns the ExDR function off.

ON : Turns the ExDR function on.

MEMO

● When the ExDR function is on, flicker may appear on the screen under fluorescent light

or mercury lamps. This is due to the principles of the ExDR, and is not a malfunction.

● There may be cases where flicker cannot be reduced even under the following condi-

tions: 1) Shutter speed is set at 1/120 in areas where the commercial electric current

frequency is 50 Hz. 2) The shutter speed is set at 1/50 in areas where the commercial

electric current frequency is 60 Hz.

● When “BLC” is set to other than “OFF”, this item will be displayed as “---” and setting will

be disabled.

ExDR LEVEL

This function sets which section of the object is to be displayed in the easiest-to-

NORMAL

view brightness level in the ExDR mode.

To make a low-lightsection of the object easy to view: Increase the level.

To make a highlighted section of the object easy to view: Decrease the level.

Setting values: –5 to NORMAL to 5

MEMO

● When the difference in brightness between objects is large, the picture may not change

even when the ExDR LEVEL is varied. This is due to the characteristics of the camera

and is not a malfunction.

● When the item “SHUTTER” is set to 1/250 or higher, “---“ is displayed and the settings to

the item “ExDR LEVEL” cannot be carried out.

● When the item “ExDR MODE” is set to OFF, the settings for the item “ExDR LEVEL”

cannot be varied.
