By using I
2C interface control, the AL251 can
also be programmed to co-ordinate with various
input resolutions, adjust screen positioning and
crop video noise from around the original input
video boundary.
The internal RGB video lookup tables (LUT),
which are controlled via the I
2C interface, can
provide gamma correction for calibrating the
color accuracy of different types of CRT’s and
improving the contrast level to display more
vivid pictures.
A
built-in
on-screen-display
(OSD)
with
programmable bitmap RAM allows custom
design icons and on-screen control panels.
Overlay function is supported to create titling or
on-screen-display menus for video adjustment.
The
AverLogic
proprietary
digital
signal
processing technology creates a highly stable
video image without tearing effects or jagged
edges. The output picture is smoother and has
less flicker than the original input signal/picture.
Please note that some features of the AL251
analog output may not apply to the digital
outputs. The following table summarizes them:
