## Abstract

An image processing apparatus measures duration of the drawing operation by using coordinate information that indicates coordinate instructed to draw and time information that indicates time when the coordinates are detected, determines predicted time in accordance with the duration of the drawing operation, and generates an drawn image by calculating the predicted coordinates after the predicted time passes. The image processing apparatus calculates a characteristic value of the drawing operation by using the coordinate information and the time information and measures the duration of the drawing operation in case the characteristic value of the drawing operation is less than predetermined threshold value.
