Display system, non-transitory computer-readable storage medium storing program, and control device

A non-transitory computer-readable storage medium storing a program for controlling a first lighting device disposed at a first position of a ceiling, a second lighting device disposed at a second position of the ceiling different from the first position, and a projector disposed at a specific position of the ceiling different from the first position and the second position and configured to project an image onto a predetermined position of a wall surface or a floor surface on which a part of a light from at least the first lighting device is incident, the program causing a processor to execute operations comprising:

• acquiring first position information indicating the first position, second position information indicating the second position, and predetermined position information indicating the predetermined position;
• accepting a first maximum light amount indicating a maximum value of a light amount of the first lighting device and a second maximum light amount indicating a maximum value of a light amount of the second lighting device;
• accepting a dimming level for adjusting the light amount of the first lighting device and the light amount of the second lighting device;
• and
• determining a correction value indicating a degree of contrast correction of the projector based on the first position information, the second position information, the predetermined position information, the first maximum light amount, the second maximum light amount, and the dimming level.

A control device for controlling a first lighting device disposed at a first position of a ceiling, a second lighting device disposed at a second position of the ceiling different from the first position, and a projector disposed at a specific position of the ceiling different from the first position and the second position and configured to project an image onto a predetermined position of a wall surface or a floor surface on which a part of a light from at least the first lighting device is incident, the control device comprising:

• at least one processor, wherein
• the at least one processor executes operations including:
• acquiring first position information indicating the first position, second position information indicating the second position, and predetermined position information indicating the predetermined position;
• accepting a first maximum light amount indicating a maximum value of a light amount of the first lighting device and a second maximum light amount indicating a maximum value of a light amount of the second lighting device;
• accepting a dimming level for adjusting the light amount of the first lighting device and the light amount of the second lighting device;
• and
• determining a correction value indicating a degree of contrast correction of the projector based on the first position information, the second position information, the predetermined position information, the first maximum light amount, the second maximum light amount, and the dimming level.
