1. A display system comprising:
an image acquisition processor unit that acquires each of a first image of a work site imaged by a first imaging device and a second image of the work site imaged by a second imaging device in a first coordinate system;
a viewpoint position calculation processor unit that calculates a viewpoint position of a worker in a second coordinate system;
a luminance adjustment processor unit that adjusts luminance of at least one of the first image and the second image based on the viewpoint position; and
a display control processor unit that combines the first image and the second image having the luminance adjusted and causes a display device to display the combined image,
wherein the viewpoint position moves between a first position and a second position in the second coordinate system, and
a relative position between a first position and a second position in the second coordinate system corresponds to a relative position between the first imaging device and the second imaging device in the first coordinate system, and
the luminance adjustment processor unit performs adjustment in a manner that the luminance of the first image becomes higher than the luminance of the second image when the viewpoint position is at the first position and the luminance of the second image becomes higher than the luminance of the first image when the viewpoint position is at the second position.
