Abstract:
1. A communication method performed between a first display apparatus comprising a first light-receiving-emitting screen capable of displaying moving pictures and receiving light and a second display apparatus comprising a second light-receiving-emitting screen capable of displaying moving pictures and receiving light by using a two-dimensional dynamic code which is a two-dimensional code changing along a time axis, wherein in the first display apparatus, a plurality of symbols composing the two-dimensional dynamic code are sequentially displayed on the first light-receiving-emitting screen along the time axis, and in the second display apparatus, the plurality of symbols are read by the second light-receiving-emitting screen, based on the read symbol, symbol-transmission-receiving-status information is acquired, the symbol-transmission-receiving-status information including at least one of information showing a relative angle between the second light-receiving-emitting screen and the first light-receiving-emitting screen, information showing a size of the symbol displayed on the first light-receiving-emitting screen, and information showing a light receiving position of the read symbol, based on the symbol-transmission-receiving-status information, at least one of display conditions is determined, the display conditions including a display angle, a size, and a display position of the symbol in displaying the two-dimensional dynamic code on the second light-receiving-emitting screen, and based on the determined display condition, the two-dimensional dynamic code is displayed on the second light-receiving-emitting screen.
