<P>PROBLEM TO BE SOLVED: To provide a drawing data recording and reproducing program, a drawing data recording and reproducing device, and a drawing data recording and reproducing method which can reduce a load of communication or display processing by decreasing a data amount to be recorded to efficiently record and reproduce data for a lecture and the like while maintaining visibility of characters, lines and the like. <P>SOLUTION: A drawing data recording and reproducing device comprises: drawing input means 3 which specifies an optional position on display means 2 and also inputs line drawing instruction signals for instructing line drawing on the specified position; drawing data recording means 51 for recording specified position coordinates and presence/absence of the line drawing instruction signals at the position coordinates as a drawing data list 421 in a drawing data storage unit 42 at predetermined time intervals; and drawing data reproduction means 60 for acquiring each position coordinate regarding the line drawing from the drawing data list 421 in sequential order to cause the display means 2 to reproduce and display a process of interconnecting position coordinates whose line drawing instruction signals are in series by line in sequential order. <P>COPYRIGHT: (C)2012,JPO&INPIT |
