1. An information processing apparatus which processes data input through a coordinate input device, comprising:
- detecting means which detects the sampling rate of the coordinate input device; and
standardizing means which standardizes writing data which is input through the coordinate input device based on the sampling rate detected by said detecting means.

Abstract
An information processing apparatus detects the sampling rate of a coordinate input device, and standardizes the writing data which is input from the coordinate input device based on the detected sampling rate. The standardized writing data is further used for signature verification or for handwritten character recognition. The information processing apparatus provides precise signature verification or handwritten character recognition even if signatures or handwritten characters for handwritten character recognition are input using digitizers having different processing rates.
