Patent ID: 6999622

Claim:
A stroke data editing device, for editing stroke data, indicating at least one stroke of a coordinate input device, comprising: a stroke data storage unit that stores stroke data, each piece of the stroke data corresponding to one stroke of the coordinate input device; a stroke data retrieving unit that selectively retrieves at least one piece of the stroke data stored within the stroke data storage unit according to a predetermined condition, the retrieved stroke data corresponding to at least one stroke included in a predetermined area; and a stroke data editing unit that edits at least one piece of the stroke data retrieved by the stroke data retrieving unit on a stroke basis, wherein: each piece of the stroke data includes at least one of storage time data indicating a storage time of storing the stroke data into the stroke data storage unit, color data indicating a color of the stroke, width data indicating a width of the stroke, and identification data indicating an identification of the coordinate input device, the predetermined condition is determined based on at least one of the storage time data and the identification data, when the predetermined condition is determined based on the storage time data, the stroke data stored in the stroke data storage unit is read successively, and a presently-read stroke data is selected when there is less than a predetermined time difference between the storage times of the presently-read stroke data and a precedently-read stroke data, and when the predetermined condition is determined based on the identification data, each piece of the stroke data includes one of a first identification data corresponding to a first stroke type and a second identification data corresponding to a second stroke type, the first stroke type giving visual information, the second stroke type visually dismissing the first stroke, and the predetermined condition is that the retrieved stroke data is free from the second identification data.
