| Title: |
Full Resolution Multiple Image Projection System and Method for Projecting Two Images in Full Resolution Adjacent Each Other |
| Abstract: |
The present invention provides a projection device (10) which comprises:
at least two high resolution input channels (12, 14) for receiving a first
and a second high resolution input signal (20, 22) having information data
for a first and a second display format, respectively,
an image recombination system (24) for combining the high resolution input
signals (20, 22) into one high resolution imaging signal having
information data for a third display format larger than either of the
first or second display formats,
a high resolution image forming display device (18) for displaying an image
corresponding to the high resolution imaging signal, and
a projection lens (26) for projecting the imaged high resolution imaging
signal onto a visualization surface (16).
The present invention also provides a corresponding method.
Due to the use of one large image forming display for displaying the two
images, no geometrical alignment problem occurs. Because one single light
beam is used for illuminating the one large image forming device, no
colour non-uniformity problem occurs between the two images.
