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.

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.

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.
