PURPOSE:To prevent a picture from being defocused in every transformation and efficiently position the picture by adding new standard points at the 2nd transformation and after to the standard point of the initial conversion and always returning these standard points to the original picture to repeat the transformations. CONSTITUTION:A new corresponding point GCP is selected on a picture showing the 1st transformation result on a monitor 1. The X and Y coordinate values of the newly selected point are converted into the X and Y coordinate values on an original picture by an original picture coordinate value deciding device 14. The coordinate values of the new GCP are inputted and stored in a new standard point register 140 and compared with the coordinate values of a compensated output picture of a register 8. The coordinate values of the new GCP on the original picture are inputted to a register 7. The new GCP on the compensated output picture corresponding to a5 is inputted from the new GCP register 140 to the register 8. The 2nd transformation is carried out by using 5 GCPs consisting of the 1st 5 GCPs and a new GCP. |
