  • Patent number: 5694315
    Abstract: A novel method for scanning multiple images in a single scanning process is disclosed. The process utilizes at least a frame holder, which contains a front frame section and a back frame section that are glued together at their top edges and are separable at least at their bottom to allow a sheet of scanning material to be placed therebetween. Each of the front and back frame sections contains a cluster of matching orientation holes on their right and left sides with a predetermined pattern to allow a computer program to achieve scan area recognition and orientation. During the scanning process, the at least one frame holder containing the image is scanned, wherein the sides of the frame holder are detected as black signals and the orientation holes are detected as white signals. Then a computer program is used to perform a previewing recognition process by detecting and carving out a scanning area corresponding to each frame holder based on the black signals and the white signals of the frame holder.
