JVC VN-V686WPU AGC, K ALC, Memo:, Sense Up, J Noise Reduction, I Stabilizer Level, [Setting values : Low,Mid,High], [Setting values : Motion,Quality]

I Stabilizer Level		This item allows you to set the adjustment level of the [Stabilizer] item H in 3 steps.
		The adjustment volume is larger if the value is set to AHighB rather than AMidB.
		When it is set to ALowB, the adjustment volume is lesser than compared to when it
		is set to AMidB.
		[Setting values : Low,Mid,High]
J Noise Reduction		When AOnB is set, image noise on the screen will be reduced.
		Memo:
		● This item is only enabled when [AGC] item K is set to AHighB or ASuperB.
		● Image noise in dark images will be reduced but the resolution will deteriorate.
		● The edges between high and low illumination area may appear rough.
K ALC		For setting the priority of ALC (feature for maintaining the video level according to
		the brightness of the object). You can select whether to assign priority to the motion
		or picture quality when the object becomes dark.
		Motion : Prioritizes movement.
				When the object becomes dark, priority is given to AGC (automatic gain
				control), and therefore this is suitable for shooting fast-moving objects.
		Quality: Prioritizes image quality.
				When the object becomes dark, priority is given to the Sense Up feature,
				and therefore this is suitable for shooting objects requiring a high picture
				quality.
		[Setting values : Motion,Quality]
	AGC	For setting the AGC (automatic gain control) level.
		Off	: Disables the AGC feature
		Mid	: When the amount of light is insufficient
		High	: When the amount of light is particularly insufficient
		Super : When the brightness level is insufficient even upon setting to AHighB.
		[Setting values : Off, Mid, High, Super]
		Memo:
		● The screen appears grainy at dark locations when the AGC feature is in use.
	Sense Up	This feature is used to raise the sensitivity level by lengthening the exposure time.
		You can specify the number of times by which the sensitivity level is to be increased
		automatically when the object becomes dark. When Ax32B is selected, the
		sensitivity is canged dynamically up to 32 times to fit to current darkness. When
		sensitivity increases, the shutter speed becomes slower and hence, movement
		becomes unnatural. When set to AOffB, Sense Up is disabled.
		[Setting values : Off, x2, x4, x8, x16, x32, x64, x128]

Memo:

●Upon raising the sensitivity level, the screen may appear grainy or white, or white defects may occur. However, this is not a malfunction.

●When [Sense Up] is set to a value other than AOffB, flickers occur under the light of fluorescent or mercury lamps. This is not a malfunction of the camera, but is due to principles related to Sense Up.

●When the [Shutter Speed] item L is set to A1/100B to A1/10000B, set [Sense Up] to AOffB.
