Abstract
An image projection system includes a second transform matrix calculator that calculates a second projection transform matrix usable to projection-transform first intersection coordinates into intersection coordinates uniformly or substantially uniformly distributed in a first area and calculates a third projection transform matrix usable to projection-transform second intersection coordinates into intersection coordinates uniformly or substantially uniformly distributed in a second area; and an image corrector that transforms image data on a first divided image by use of the second projection transform matrix, transforms image data on a second divided image by use of the third projection transform matrix, and translates at least one of the first divided image and the second divided image toward a borderline between the first divided image and the second divided image to delete a gap between the first divided image and the second divided image.
