ABSTRACT:
Optics for a document scanner arc disclosed which permit information on a document to be optically reorganized so they may be input as a single image to the lens of a single charge coupled device camera without the need for moving optics or moving document arrangements to sequentially image portions of the document to the input lens of the camera. The optics are mirrors in a fixed, stationary arrangement with respect to each other, between the camera lens and a document to be read. All the information to be read on the document is reflected between the mirrors and is thereby transposed physically before being input to the lens of the camera as a single image. After the single image input to the camera is scanned and stored the image portions are re-transposed using a computer and software utilizing a transposition algorithm to re-create the information on the document in their proper order. The single image may also be passed through optical filters to delete portions of the image before it is input to the lens of the camera so that the camera can only scan certain portions of the image having predetermined colors.
