	With a 16:9 screen and a
	standard LS-10i (without
	an anamorphic lens), the
	upper and lower portions
	of the screen are
	masked, but the
	geometry of the active
	image area is
Cinema	unchanged.	2.35:1
	With a 2.35:1 screen and
	an anamorphic lens, the
	video processor scales
	the 2.35:1 image so that
	the active image area fills
	the 16:9 chip surface,
	eliminating the black
	bars. The secondary,
	anamorphic lens then
	restores the proper
	geometry to the 2.35:1
	image.
	A 16:9 image is scaled
	NON-linearly (more on
	the sides than in the
Virtual	center) to fit a 2.35:1	16:9
	screen.
