Patent ID: 6924823

Claim:
A method of processing at least a portion of an image to enable display of a processed portion of the image, said method comprising: representing the portion of the image by at least one B'ezier curve that is a function of a parameter t and defined by a plurahty of control points such that the B'ezier curve intersects one of the control points when the parameter t has a minimum value and intersects another of the control points when the parameter t has a maximum value; affine transforming each of the plurality of control points based on an enlarging ratio or a reducing ratio of the portion of the image to obtain a transformed B'ezier curve defined by a plurality of transformed control points; determining whether the transformed B'ezier curve is to be drawn within an actual drawing area of a display; and when the transformed B'ezier curve is to be drawn within the actual drawing area of the display, setting a number of divisions of the parameter t of the transformed B'ezier curve based on a ratio of a drawing area of the transformed B'ezier curve to the actual drawing area of the display, determining coefficients of the transformed B'ezier curve based on the number of divisions cf the parameter t of the transformed B'ezier curve, generating a plurality of curve defining points of the transformed B'ezier curve based on the determined coefficients, the number of curve defining points corresponding to the number of divisions of the parameter t, and drawing the transformed B'ezier curve based on the plurality of curve defining points.
