ABSTRACT:
A digital image display system and method for displaying a digital image in a large format are provided. The system includes a frame buffer for storing the digital image, which is projected via a plurality N of projection units. Each projection unit projects a section of the digital image which is 1/Nth of the digital image plus an overlap portion of each of its neighboring sections. Thus, when the sections are projected, the portions of the image corresponding to the edges between projection units will be overlapped. The intensities of the overlapped portions are typically modulated to ensure that, in the large format image, the overlapped portions receive the same amount of illumination as the non-overlapped portions. The resultant image will have no seams between projection units. The projection units are assumed to be mis-aligned and the misalignment is compensated for by transforming each section of the image in accordance with the misalignment of the projection.
