Projector control apparatus, projector system, and projector control method

A projector control apparatus that causes plural projectors to collectively project an image by individually projecting a different one of segment images into which the image is divided, the projector control apparatus comprising:

• a spatial distribution information obtaining unit which obtains information indicating a distribution of one or more viewers that view the image in a space where the projectors are mounted;
• a mode selecting unit which selects, using the information indicating the distribution of the one or more viewers, one of modes including (i) a first mode in which a width of a projection area is a first width and (ii) a second mode in which the width of the projection area is a second width larger than the first width, the projection area being an area in which the image is projected;
• and
• a projector control unit which changes arrangement of the segment images by controlling, according to the mode selected, each of projection directions in which the projectors project the segment images,
• wherein in the case where the number of the projectors is n×m, the projector control unit is configured to control each of the projection directions in which the projectors project the segment images to (i) arrange the segment images in n rows and in columns when the mode selecting unit selects the first mode, and (ii) arrange the segment images in one row and (m×n) columns when the mode selecting unit selects the second mode.
