Abstract
A projector array includes a plurality of projectors, which together project images into a projection area on a projection surface. Aspect ratios are normalized for all of multiple images designated for display. The normalized aspect ratios are aligned at a common central point. An aspect ratio of a minimum rectangular shape is determined that will encompass all of the aligned aspect ratios. A maximum rectangular projection area is determined within the projection area having the same aspect ratio as the minimum rectangular shape. The center of the maximum rectangular area is designated as a centralization point. Each of all of the multiple images is sequentially projected into the projection area. Each image is scaled for display at its aspect ratio and is displayed centered at the centralization point.
