CAMERA ALC/ExDR Screen (Continued)

Item					Function & Setting		Initial Value

AGC MODE	Sets the maximum gain of the AGC (Auto Gain Control), which electronically in-						10 dB
	creases the gain when the object is under low light conditions.
	OFF			: Turns the AGC off.
	10 dB : According to the brightness of the object, gain is increased by up to 10 dB
	20 dB : According to the brightness of the object, gain is increased by up to 20 dB
	SUPER : Use this setting when brightness is still insufficient under the “20 dB”
				setting.

			MEMO
			MEMO
		● Note that increasing gain affects picture quality.
		● When the “SUPER” setting is used, the AGC operation may take a while to adjust to
				sudden drastic changes in the brightness level.

SENSE UP	This function is used to increase the sensitivity by extending the exposure time.						OFF
	Increasing this value slows the shutter speed and motion may appear unnatural.
	When the item “SHUTTER” is set to “1/250” or more, the SENSE UP item does not
	work and “---“ is displayed as the item name in the CAMERA ALC/ExDR Screen.
	Setting values: OFF, x2

		● When SENSE UP is activated, the picture may become rough and whitish, and subject
				to white blemishes.
		● When the setting of the “SENSE UP” function is not OFF, flicker may appear on the
				screen under fluorescent light or mercury lamps. This is due to the principles of the
				SENSE UP, and is not a malfunction.
		● There may be cases where flicker can not 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.

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/ExDR Screen.
	OFF : Turns the ExDR function off.
	ON : Turns the ExDR function on.

		● 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.

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.
