Image projecting system, information processing apparatus, and method for image projecting

An image projecting method for projecting onto a plurality of surfaces in a projection region, each surface having an electric screen in a projection system including, for each surface of the plurality of surfaces, a plurality of projector sets including an upper projector and a lower projector so that each surface has different corresponding upper and lower projectors, the method comprising:

• receiving, for each surface of the plurality of surfaces in the projection region, an adjustment value to increase or decrease an effective distance from an imaging device to a curved position of the surface;
• determining, for each surface of the plurality of surfaces, a curved shape of the surface in accordance with a change of distortion corresponding to the effective distance that was increased or decreased by the received adjustment value;
• calculating, for each surface of the plurality of surfaces, correction parameters to correct the distortion of projection images projected onto the surface, in accordance with the determined curved shape of the surface;
• dividing an image into a plurality of divided images in accordance with positions and sizes of the each surface of the plurality of surfaces in the projection region;
• and
• controlling the plurality of projector sets to respectively project the plurality of divided images onto the plurality of surfaces, each projector set of the plurality of projector sets corresponding to a different projection surface of the plurality of surfaces and projecting a corresponding divided image of the plurality of divided images onto the different projection surface using the corresponding correction parameters for the surface.
