When the manuscript is read with the non-contact scanner, the change in the position of the lighting might generate the shadow in the manuscript, and be deteriorated of the image quality. Up to now, the user has adjusted it by trying to read a standard seat again. However, this was time-consuming, and it was not possible to correspond to the lighting change after the manuscript had been set. We propose the reading method to correct the shading wave form dynamically by arranging six specular balls around the manuscript, reading the specular ball, and presuming the lighting environment by this specular ball image. |
