Claim 5:
6. A projection system comprising
a projection device including:
a projector communication device,
a light projection device,
an image sensor, and
a projector processor;

a first display device including:
a first display communication device,
a first display,
a first operation device, and
a first display processor configured to display, on the first display, a captured image received by the first display communication device from the projection device, generate a first display drawing image based on a drawing operation accepted by the first operation device while the captured image is being displayed, and transmit, using the first display communication device, the generated first display drawing image to the projection device;

a second display device including:
a second display communication device,
a second display,
a second operation device, and
a second display processor configured to display, on the second display, a captured image received by the second display communication device from the projection device, generate a second display drawing image based on a drawing operation accepted by the second operation device while the captured image is being displayed, and transmit, using the second display communication device, the generated second display drawing image to the projection device, wherein

the projector processor is configured to
communicate with the first display device and the second display device, using the projector communication device,
project, using the light projection device, the first display drawing image received from the first display device and the second display drawing image received from the second display device, and
transmit, to the first display device and the second display device, a captured image obtained by capturing, using the image sensor, a range including a projection target on which the first display drawing image and the second display drawing image are projected.
