JVC VN-C625 manual Average Peak, Large Peak value, Set value, Shutter

Item			Function/Set Value	Initial Value
Average : Peak	Sets the method of exposure detection according to ratio be-			8:2
	tween the average and peak values.
	• Large Average value : Use this setting when areas other than
			those highlighted are dark and unclear.
			(Example: 10:0)
	• Large Peak value		: Use this setting when halation occurs
			at the highlighted areas.
			Use this setting when areas other than
			those highlighted are dark and unclear.
			(Example: 5:5)
	Set value		: 10:0, 9:1, 8:2, 7:3, 6:4, 5:5
Shutter	Sets the speed of the electronic shutter.			1/60
	Set value : 1/60, 1/100, 1/250, 1/500, 1/1000, 1/2000, 1/4000,
		1/10000
	Notes
	•	To reduce flickering that occurs under fluorescent
		lighting, set the shutter speed to 1/100 if your local power
		supply frequency is 50 Hz, and to 1/60 if it is 60 Hz.
	•	The higher the shutter speed, the more prominent will
		be the smear phenomenon. This is a phenomenon that
		is characteristic of CCDs, whereby white stripes appear
		at the top and bottom of a bright light source.
AGC	Sets the maximum gain of the AGC (Auto Gain Control), which			10 dB
	electronically increases the gain when the object is under low
	light conditions.
	OFF	: Disable AGC.
	10 dB : Increase gain by a maximum of 10 dB according to
		the brightness of the object.
	20 dB : Increase gain by a maximum of 20 dB according to
		the brightness of the object.
	Note
	• The screen may appear grainy at dark places when the
		gain level is increased.
BLC	Sets the backlight compensation function. Use this setting when			OFF
	an object appears dark using the Auto Iris function due to the
	presence of a bright light source behind the object. This func-
	tion makes it possible to place an unnecessary light source
	outside the photometry area.
	OFF	: Disable BLC.
	Area 1 to Area 4: Set accordingly by referring to the diagram below.
