Display control apparatus, image projection system, and control method

An image projection system comprising:

• a plurality of projection devices arranged in different positions;
• an image capturing device configured to capture a plurality of projection images projected in a projection target region by the plurality of projection devices;
• a setting unit configured to set a target overlap width with respect to an overlap region in which at least two of adjacent projection images of the plurality of projection images overlap each other;
• an image obtaining unit configured to obtain a captured image obtained by capturing the plurality of projection images projected in the projection target region;
• a calculation unit configured to calculate the overlap width of the overlap region of the at least two adjacent projection images on the basis of the captured image;
• and
• an indicator generation unit configured to generate, on the basis of the overlap width, an adjustment indicator that guides a positional adjustment of the projection image such that the at least two adjacent projection images overlap each other by the target overlap width.

A control method for a display control apparatus that controls to display a single image by causing a plurality of projection images projected in a projection target region by a plurality of projection devices arranged in different positions to overlap each other by a predetermined overlap width, the control method comprising:

• setting a target overlap width with respect to an overlap region in which at least two of adjacent projection images of the plurality of projection images overlap each other;
• obtaining a captured image obtained by capturing the plurality of projection images projected in the projection target region;
• calculating the overlap width of the overlap region of the at least two adjacent projection images on the basis of the captured image;
• and
• generating, on the basis of the overlap width, an adjustment indicator that guides a positional adjustment of the projection image such that the at least two adjacent projection images overlap each other by the target overlap width.

A non-transitory computer readable storage medium that stores a program causing a computer to execute a control method for a display control apparatus that displays a single image by causing a plurality of projection images projected in a projection target region by a plurality of projection devices arranged in different positions to overlap with each other by a predetermined overlap width, the control method comprising:

• setting a target overlap width with respect to an overlap region in which at least two of adjacent projection images of the plurality of projection images overlap each other;
• obtaining a captured image obtained by capturing the plurality of projection images projected in the projection target region;
• calculating the overlap width of the overlap region of the at least two adjacent projection images on the basis of the captured image;
• and
• generating, on the basis of the overlap width, an adjustment indicator that guides a positional adjustment of the projection image such that the at least two adjacent projection images overlap each other by the target overlap width.
