Virtual space connection device

A system that virtually connects a first space and a second space with each other by transmitting, to the second space separated from the first space, a first picked-up image signal obtained by picking up an image of the first space by a first imaging unit in the first space, receiving, from the second space, a second picked-up image signal obtained by picking up an image of the second space by a second imaging unit in the second space, and projecting, on a first projection target unit provided with a first camera hole for causing the first imaging unit to pick up the image of the first space in the first space, an image on the basis of the second picked-up image signal received from the second space by a first projector, the system comprising:

• a region setting section that sets, as a search region, a region on which the image is projected by the first projector and which is surrounded by a plurality of end sides, the region including the first camera hole, and sets, as a specific output region, a region surrounded by the plurality of end sides after at least one of the plurality of end sides of the search region is moved toward the first camera hole;
• a signal processing section that generates post-processing image data by performing image signal processing on the second picked-up image signal in such a way that a luminance value of the image projected onto the specific output region by the first projector becomes equal to or smaller than a specific value;
• and
• a device control section that causes the first projector to project the image on the basis of the post-processing image data,
• wherein the region setting section:
• sets, as a first luminance region, a region surrounded by the moved end side after any end side among the plurality of end sides of the search region is moved toward the first camera hole, and an other end side;
• sets, as a second luminance region, a region other than the first luminance region in the search region;
• causes an image with a first luminance value to be projected on the first luminance region, causes an image with a second luminance value to be projected on the second luminance region, the second luminance value being higher than the first luminance value;
• and
• sets the specific output region on the basis of a plurality of image patterns projected on the first luminance region and the second luminance region in accordance with the movement of the any end side.
