3.1 Picture Adjustment
When [Picture Adjustment] is selected at the “Screen Manager” dialog box
and “Center” of the operation pad is pressed, the menus for picture adjustment
appear in the dialog box.
Select the item to be adjusted and press “Center” of the operation pad.
Contrast/Brightness
• The contrast (difference in intensity) and brightness of the reproduced
picture can be adjusted.
Fig. 1.4

Adjustment Procedure for Average Brightness
Fig. 1.5
(1) Select “Contrast/Brightness” for maximum brightness.
(2) Select “Size” at “Picture Adjustment” of the “Screen Manager” dia-
log box.
When the screen size is reduced to the minimum, a glimmer frame
(raster) appears outside the reproduced picture.
(3) Select “Contrast/Brightness”.
Decrease the brightness until the raster has the same brightness as
the available picture area (until the raster disappears).
The brightest picture will be reproduced with great contrast.
(4) Resume the original size and adjust the contrast to the desired one.

tions can be adjusted.

Moire Effect on Display Screen
• When the picture has diagonal lines as part of the image, poor interlac-
ing makes them appear to be interwoven in the moire effect. This effect
is more evident in diagonal picture information, when the interlacing
varies in successive frames.
The poor interlacing can be corrected to reduce this moire effect.
