Abstract
A projector including an imaging section that detects operation performed on a screen, a coordinate calculating section that calculates position information representing the position in a display area where the operation detected by the imaging section has been performed, and a control section that produces a drawn object based on the position information calculated by the coordinate calculating section and causes both the produced drawn object and a partial image to be displayed in the display area, and the control section switches the operation mode of the display apparatus between a first operation mode in which the position information is transmitted to another projector via a USB I/F section and a second operation mode in which the position information is converted into image position information representing the position in an image displayed on the screen and causes the display apparatus to operate in the selected mode.
