PROBLEM TO BE SOLVED: To provide an image processing apparatus and an image processing method that increase Bezier approximation accuracy within the range of relatively fast processes and within the range that the amount of data permits, so as to increase the Bezier approximation accuracy within a predetermined period of processing time. SOLUTION: Anchor points are set for rough-contour vector data gained (S30) and control points are set through function approximation (S60). In-interval error values are calculated for every function approximation interval where function approximation is performed (S70) and an in-interval maximum error value is identified (S80). Next, a determination is made as to if a period of processing time has exceeded a predetermined period of time (S110), and a determination is made as to if the amount of data generated has reached a predetermined amount of data (S130). Until the amount of data generated reaches the predetermined amount of data or until the time elapsed exceeds the predetermined period of time, the interval with the in-interval maximum error value is divided, and a calculation process with an accuracy close to that of the function approximation process is performed for that interval (S140, S150, S160).
