key on the remote control, until a new programming is performed.
7.1.17 CONTRAST
The contrast of an image is defined as the relation between dark and light
colors. An image of high contrast is often regarded as 'hard', as compared
to the 'soft' feeling of a low contrast image. Low contrast is recommended
for long term viewing, while high contrast is used to enhance details. Use
the CONTR keys on the remote control (RC) to adjust the contrast. Also
see Brightness. The contrast setting is stored individually for each mode.
7.1.18 BRIGHTNESS
The brightness is the amount of white in an image. The brightness is
adjusted to the ambient lighting conditions. Usually, a bright, low contrast
image is preferred. Use the BRIGHT keys to adjust brightness. See also
