Abstract: There is provided a projection system including: a projector configured to project an image on a projection surface; and a computer configured to communicate with the projector and instruct the projector to project the image in accordance with an operation by a user. The projector includes a first processor that sends information on an operation state of the projector to the computer while communicating with the computer. The computer includes a display and/or a speaker and a second processor that makes a notification based on the information from the projector by causing the display to display a notification and/or by causing the speaker to output a voice.

Abstract: A projecting apparatus includes a projector configured to output projected light; a receiver configured to obtain from outside, image data of a target image projected by the projector; and a processor configured to control operation of the projector. The processor is configured to set a light intensity of the projected light to a light decreased state lower than a standard value when the image data is not obtained by the receiver.
