<P>PROBLEM TO BE SOLVED: To provide the display control method and device of a display video and a light output reading display control method and device from a display video for collecting and processing data by accurately reading necessary liquid crystal display by using technology of a bar code reader. <P>SOLUTION: A plurality of binary multi-unit codes, for example, "11000001" which are constituted of preliminarily determined two or more bit numbers respectively are determined so as to be made to correspond to a plurality of elements to be displayed such as character symbols which can be displayed on a display face, and a binary serial light output signal acquired by flickering-controlling a display video displayed on the display face according to those binary multi-unit codes which are made to correspond to the plurality of elements to be displayed respectively. The binary serial light output signal can be displayed by decoding a binary digital received light output read by the bar code reader by referring to the code table for code conversion. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
