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, anda 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.
