A method and system may be used to design and control the manufacture of a surgical guide for implanting a prosthetic component. The system includes a bone surface image generator, a surgical guide image generator, and a surgical guide image converter. The bone surface image generator receives three dimensional bone anatomical data for a patient's bone and generates a bone surface image. The surgical guide image generator generates a surgical guide image from the bone surface image and an image of a prosthesis imposed on the bone surface image. The supporting structure of the generated surgical guide image conforms to the surface features of the three dimensional bone surface image. The surgical guide image is converted by surgical guide image converter into control data for operating a machine to form a surgical guide that corresponds to the surgical guide image.

Any given part is cut out from a distorted circular image photographed by use of a fisheye lens and converted into a planar regular image with less distortion. A virtual sphere H having a radius R on a distorted circular image S on an XY plane is defined, thereby allowing a user to designate a cut-out center point P, a magnification m, and a planar inclination angle φ. A visual line vector n passing through an intersecting point Q immediately above the point P is determined to define an UV orthogonal coordinate system having an orientation depending on the angle φ on a plane orthogonal to a visual line vector n at a point G in which a distance between two points OG is given as m·R. The UV orthogonal coordinate system is curved along the side face C of a “virtual cylindrical column in which the point G forms one point on the side face to have a straight line V′ parallel to the V axis and also passing through the point O as a central axis,” thereby defining the UV curved coordinate system.

When an output unit is capable of operation at a frame rate F and a resolution of x×y pixels, an imaging unit or an image input unit converts an image into an imaged frame in an internal data format having the frame rate F and a resolution of ix×jy pixels.

At this time, the image converter carries out predetermined resolution conversion based on a moving velocity of the image by blocks each having a predetermined size. Thus, such visual effect that an observer of the image of the output frame perceives the image at a resolution exceeding the actual resolution of the output frame is achieved.
