<P>PROBLEM TO BE SOLVED: To provide a display device, a light receiver, a communication system and a communication method, which reliably and efficiently transmit a large capacity of information. <P>SOLUTION: The display device 1 includes a light emitting part 11 displaying motion picture images, and an input terminal 2 includes a light receiving part 22 receiving light. A motion picture two-dimensional code is constituted of a plurality of symbols including a data symbol 54 and an anchor symbol 53. The display device 1 is designed to display the anchor symbol 53 by means of the light emitting part 11 every time or a plurality of times the data symbol 54 is displayed, so that a large capacity of information is efficiently transmitted from the display device 1 to the input terminal 2. In addition, the input terminal 2 reads the symbols by means of the light receiving part 22 and also detects the anchor symbol 53 to locate the light receiving positions of the respective symbols in the light receiving part 22, thereby further allowing the large capacity of information to be reliably transmitted. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
