Claim 3:
4. A projection system comprising
a first projection device including:
a first light projection device,
a first image sensor,
a first projector communication device, and
a first projector processor configured to project, using the first light projection device, an image received by the first projector communication device, generate a first captured image by capturing, using the first image sensor, a range including a projection target of the first light projection device, and transmit the first captured image using the first projector communication device;

a second projection device including:
a second light projection device,
a second image sensor,
a second projector communication device, and
a second projector processor configured to project, by the second light projection device, an image received by the second projector communication device, generate a second captured image by capturing, using the second image sensor, a range including a projection target of the second light projection device, and transmit the second captured image using the second projector communication device; and

a display device including:
a display,
an operation device,
a display communication device, and
a display processor configured to:
communicate with the first projection device and the second projection device using the display communication device;
display, in a first region of the display, the first captured image received from the first projection device, generate a first region drawing image based on a drawing operation corresponding to the first region accepted by the operation device, transmit the first region drawing image to the first projection device; and
display, in a second region of the display, the second captured image received from the second projection device, generate a second region drawing image based on a drawing operation corresponding to the second region accepted by the operation device, and transmit the second region drawing image to the second projection device.
