❿ Storing Changes for Lens Shift, Zoom, and Focus [LENS 
MEMORY]
The	 adjusted	 values	can	be	stored	 in	projector	 memory	when	using	the	LENS	 SHIFT,	 ZOOM	and	FOCUS	 buttons	
of	the	 projector. 	Adjusted	 values	can	be	applied	 to	the	 signal	 you	selected. 	This	 will	eliminate	 the	need	 to	adjust	 lens	
shift,	focus,	 and	zoom	 at	the	 time	 of	source	 selection. 	There	 are	two	 ways	 to	save	 adjusted	 values	for	lens	 shift,	 zoom,	
and	focus.
Function	nameDescription page
REF.	LENS	MEMORYAdjusted	values	common	to	all	the	input	signals.If	no	adjusted	values	are	stored	in	[LENS	MEMORY],	the	values	stored	in	[REF. 	LENS	MEMORY]	will	be	applied	for	lens	adjustment.
→	page	130
LENS	MEMORYAdjusted	values	for	each	input	signal.Use	the	adjusted	values	for	the	signal	with	a	different	aspect	ratio	or	resolution. 	The	adjusted	values	can	be	applied	at	the	time	of	source	selection. →
	page	121
NOTE:
•	 The	lens	shift,	zoom,	and	focus	adjustments	can	be	performed	with	the	remote	control.	(→ page 27, 29, 30)
•	The	NP25FL	lens	does	not	support	the	Lens	Memory	function.
•	 Be	sure	to	perform	[CALIBRATION]	after	replacement	of	the	lens.
Usage Example
When	
you	wish	 to	display	 on	a	screen	 having	a	4:3	 aspect	 ratio	an	NTSC	 or	other	 4:3	aspect	 ratio	signal	 and	an	
SXGA	or	other	5:4	aspect	ratio	signal:
Perform	 shift,	focus,	 and	zoom	 adjustments	 to	set	 the	 vertical	 screen	size	of	the	 vertically	 tall	5:4	 aspect	 ratio	signal	
to	standard.
Both	4:3	aspect	ratio	signals	and	5:4	aspect	ratio	signals	can	now	be	displayed.
Note	 that	with	 these	 shift,	focus,	 and	zoom	 adjustments,	 the	4:3	aspect	 ratio	signal	 will	become	 smaller	on	the	
screen.
To	eliminate	 this	size	 reduction,	 adjust	the	shift,	 focus	 and	zoom	 to	the	 optimum	 condition	 for	each	 of	the	 4:3	aspect	
ratio	signal	and	the	5:4	aspect	ratio	signal.
Memory	(storage)	of	each	of	these	values	will	permit	projection	at	an	optimum	condition	upon	signal	switching.
To store your adjusted values in [REF. LENS MEMORY]:
1.	 Press	the	MENU	button.
	 The	menu	will	be	displayed. 	
2. Press the ▶	button	to	select	[SETUP]	and	press	the	ENTER	button.
3.  Press the ▶	button	to	select	[INSTALLATION	(1)].

TIP:
To	call	up	the	adjusted	values	from	[LENS	MEMORY]:
1.	 From	the	menu,	select	[ADJUST]	→	[LENS	MEMORY]	→	[MOVE]	and	press	the	ENTER	button.
	 The	confirmation	screen	will	be	displayed.
2. Press the ◀	button	to	select	and	[YES]	and	press	the	ENTER	button.
	 The	adjusted	values	stored	in	[LENS	MEMORY]	will	be	applied	to	the	current	signal. 	
To	automatically	apply	the	adjusted	values	at	the	time	of	source	selection:
1.	 From	the	menu, 	select	 [SETUP]	→	[REF. 	LENS	 MEMORY]	→	[LOAD	 BY	SIGNAL]	 and	press	 the	ENTER	 but-
ton.
2.	 Press	the	v	button	to	select	and	[ON]	and	press	the	ENTER	button.
  This will move the lens automatically to the position at the time of source selection according to the adjusted val-
ues. 
NOTE:	 The	Lens	 Memory	 function	may	not	produce	 a	completely	 aligned	image	(due	to	tolerances	 in	the	 lenses)	 using	the	adjusted	
values	 stored	 in	the	 projector.	 After	calling	 up	and	 applying	 the	adjusted	 values	from	the	Lens	 Memory	 function,	 finely	adjust	 the	
lens shift, zoom and focus to produce the best possible image.

⓫ Displaying a Picture Using [EDGE BLENDING]
The	EDGE	BLENDING	function	allows	a	multi-screen	image	with	high	resolution	to	be	displayed	on	a	large	screen.
This	function	adjusts	overlapping	edges	of	images	projected	from	each	projector	to	uniform	multi-screen	images.
NOTE:
•	 For	projector	throw	distances,	refer	to	“Throw	distance	and	screen	size”	on	page	219, 220, 221.
•	 Before	performing	 the	Edge	 Blending	 function,	 place	the	projector	 in	the	 correct	 position	 so	that	 the	image	 becomes	 square	in	
the appropriate size, and then make optical adjustments (lens shift, fo\
cus, and zoom).
Before explaining use of the Edge Blending function
This	section	 explains	 the	case	 for	“Example: 	Placing	 two	projectors	 side	by	side”. 	As	 shown,	 the	projected	 image	on	
the	left	is	referred	 to	as	 “Projector	 A”	and	 the	projected	 image	on	the	 right	 is	referred	 to	“Projector	 B”.	Unless	 otherwise	
specified	hereinafter,	the	 “projector”	is	used	to	mean	both	A	and	B.
Example:	Placing	two	projectors	side	by	side
Edge	Blending	area
Projected area Projected area
Projector	A Projector	B
Preparation:
•	 Turn	on	the	projector	and	display	a	signal.
•	 To	use	two	or	more	 projectors,	 you	have	 to	turn	 on	[CONTROL	 ID]	from	 the	menu. 	For	 more	 information,	 refer	to	
“Setting	ID	to	the	Projector	[CONTROL	ID]” 	on	page	131.

3. Convenient Features
TIP:
•	 When	displaying	a	signal	with	a	different	resolution,	perform	the	Edge	Blending	function	from	the	start.	
•	 Setting	of	[MARKER]	will	not	be	saved	and	return	to	[OFF]	when	the	projector	is	turned	off.	
•	 To	display	or	hide	the	marker	while	the	projector	is	running,	turn	on	or	off	[MARKER]	from	the	menu.
•	 If	you	want	 to	make	 differences	 in	white	 balance	 and	brightness	 between	projectors	 less	visible,	 adjust	[REF.	WHITE	 BALANCE]	
and	[MULTI-SCREEN	COMP.]	to	obtain	the	possible	best	results.	(→ page 129)
Black Level Adjustment
If	you	 notice	 any	differences	 in	the	 brightness	 of	an	 image,	 use	[BLACK	 LEVEL]	to	adjust	 the	darkest	 part	or	the	 level	
of	brightness.
NOTE: 
This	function	is	enabled	only	when	[MODE]	is	turned	on.
Adjustable	area	varies	depending	on	what	combination	of	[TOP],	[BOTTOM],	[LEFT]	and	[RIGHT]	are	turned	on.
