A display control apparatus causes a plurality of images to be arranged and projected by a plurality of projection units. An obtaining unit obtains an overlap value for indicating a width at which a portion of a first image and a portion of a second image overlap. A control unit causes the plurality of projection units to project the plurality of images which includes at least the first image and the second image by overlapping the portion of the first image and the portion of the second image by a width based on the overlap value. Also, the control unit causes the portion of the first image and the portion of the second image to overlap by the width based on the overlap value by changing a size of a projected image.
