Patent ID: 6970581

Claim:
An information processing apparatus which processes data input through a coordinate input device, said information processing apparatus comprising: inputting means for inputting writing data through the coordinate input device; detecting means for detecting the sampling rate of the coordinate input device based on the writing data and time information; and standardizing means for standardizing writing data which is input through the coordinate input device, the standardizing being based on the sampling rate detected by said detecting means, wherein the writing data of the detected sampling rate is standardized to the writing data of a predetermined sampling rate, and wherein said detecting means includes: display means for displaying a graphical pattern for sampling rate detection on an input screen of the coordinate input device; instructing means for instructing a user to trace the displayed graphical pattern; obtaining means for obtaining the time period and the total number of samplings during the time that the displayed graphical pattern is traced by the user; and calculating means for calculating the sampling rate based on the obtained time period and the obtained total number of samplings.
