1. A written data processing apparatus configured to digitize a movement trajectory of a writing instrument when the writing instrument is used to write on a located paper medium, comprising:
a detection portion configured to detect a position of the writing instrument in proximity to a prescribed region in which the paper medium is to be located; and a processor configured to:
obtain coordinate data corresponding to a position detected by the detection portion, and obtain time data corresponding to obtaining time when the coordinate data is obtained;determine whether a first position specified by the obtained coordinate data and a second position within a check region coincides with each other or not, the check region being at least one region determined based on a type of the paper medium out of the prescribed region;store, when the first position and the second position are determined not to coincide, the coordinate data and the time data in a first storage portion;select, when the first position and the second position are determined to coincide with each other, either of a save processing, an addition processing, and a deletion processing based on at least either of the coordinate data and the time data;create, when the save processing is selected, a first image file containing a dot or a line drawing indicated by the coordinate data stored in the first storage portion, and store the created first image file in a second storage portion;create, when the addition processing is selected, a second image file containing a dot or a line drawing indicated by the coordinate data corresponding to the first image file stored in the second storage portion and a dot or a line drawing indicated by the coordinate data stored in the first storage portion, and storing the created second image file in the second storage portion as the first image file; anddelete, when the deletion processing is selected, the first image file from the second storage portion. |
