1. A projecting apparatus comprising:
a projector configured to output projected light;
an operation reception unit configured for receiving input operations from a user;
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,
wherein,
in a case in which the image data is not obtained by the receiver, the processor is configured to set a light intensity of the projected light to a light decreased state lower than the light intensity of the projected light in a case in which the image data is obtained by the receiver, and simultaneously, to allow the projector to project the target image including a display of at least one of an index, a symbol, and a letter so as to enable a user to perform an input operation using the operation reception unit to cause the processor to adjust a focus while continuing the light decreased state of the projected light.
