Examining Image Quality Further

In addition to color adjustments, adjustments to advanced sharpness and the amount of light from the
lamp can also be made to match the image in search of the best picture.

Sharpness (Advanced) adjustment

If "Thin Line Enhancement" is set in the +
direction, hair and the detailed areas of clothing
will be emphasized.
If "Thick Line Enhancement" is set in the +
direction, the areas emphasized by "Thin Line
Enhancement" will be hardly emphasized. Instead,
the rough areas of the entire subject, such as
contour and background, will be emphasized,
resulting in a sharp image.
Setting "Horiz. Line Enhancement" / "Vert. Line
Enhancement" to the + side will enhance the
image sharpness in the horizontal / vertical
direction. Setting them to the - side will give a soft
image.
This cannot be adjusted during input of computer
image signals.

Auto Iris (automatic aperture) setting

When "Auto Iris" is on, the light intensity from
the lamp is automatically controlled according to
the brightness of images, and you can get higher
contrast and rich images. Tracking speed of the
light intensity control in response to changes in
brightness of images can be set to either "Normal"
or "High Speed" depending on your preference.
Setting is not possible when "Color Mode" is set
to "x.v. Color."
An operation sound of Auto Iris function may
*
be emitted while projecting some images. This
is not a failure of the projector.
