Graphical image ellipse information determining device, has ellipse computation device computing ellipse parameter based on coordinates of ellipse points, where ellipse parameter represents information about form and/or location of ellipse

摘要

The device has a coordinate determining device (110) for determining coordinates (114) of two ellipse points. The coordinate determining device is designed to determine parameters of two curved line segments, and determines the coordinates of the respective ellipse points based on the parameters of the line segments. An ellipse computation device (120) computes an ellipse parameter (122) based on the coordinates of the respective ellipse points. The ellipse parameter represents information about a form and/or location of the ellipse. Independent claims are also included for the following: (1) a method for determining information about a form and/or location of an ellipse in a graphical image (2) a computer program for executing a method of determining information about a form and/or location of an ellipse in a graphical image.
