A projection method includes detecting a first section formed of a flat surface at a projection surface, detecting a second section formed of a concave surface at the projection surface, projecting image light in a first visual aspect onto the first section by a projector, and projecting image light in a second visual aspect different from the first visual aspect onto the second section by the projector.

Projection method and projector

A projection method includes detecting a first distance between a projector and a first portion of a projection surface, detecting a second distance between the projector and a second portion of the projection surface, detecting a third distance between the projector and a third portion of the projection surface, projecting image light in a first visual aspect according to the first distance onto the first portion by using the projector, projecting image light in a second visual aspect according to the second distance onto the second portion by using the projector, and projecting image light in a third visual aspect based on the first and second visual aspects onto the third portion by using the projector when the third distance is longer than the first distance but shorter than the second distance.

A projection image including a test pattern is projected on a projection surface. The projection image is moved in a first direction. An image of the projection image is captured. A change in the test pattern contained in the projection image the image of which has been captured is detected. When a change in the test pattern is detected, it is determined that the projection image has reached an end of the projection surface.

An image display system includes a first image display device and a second image display device. The first image display device includes a first communication section adapted to perform communication with the second image display device, a first display section adapted to display a first image based on first image information, a storage section adapted to store second image information, an operation section adapted to receive a first operation, and a control section adapted to make the first communication section transmit the second image information corresponding to the first operation received by the operation section to the second image display device. The second image display device includes a second communication section adapted to perform communication with the first image display device, and a second display section adapted to display a second image based on the second image information received via the second communication section.
