Item	Function/Set Value	Initial Value
Sense Up	This function is used to increase the sensitivity by extending	OFF
	the exposure time. 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.
	Setting values: OFF, x2, x4, x8, x16, x24, x32
	• 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 conditions: 1) Shutter speed is set at 1/100
	in areas where the commercial electric current frequency is 60
	Hz. 2) The shutter speed is set at 1/60 in areas where the com-
	mercial electric current frequency is 50 Hz.
ExDR Mode	The ExDR function synthesizes pictures captured at a shutter	OFF
	speed of 1/100 and those captured at higher shutter speeds to
	help monitor objects having large differences in brightness lev-
	els.
	When the "SHUTTER" function is set to "1/250" or a higher,
	this function does not work.
	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 conditions: 1) Shutter speed is set at 1/
	100 in areas where the commercial electric current frequency
	is 60 Hz. 2) The shutter speed is set at 1/60 in areas where
	the commercial electric current frequency is 50 Hz.
ExDR Level	This function sets which section of the object is to be displayed	0
	in the easiest-to-view
	brightness level in the ExDR mode.
