Abstract: A framing aid for a handheld document capture device such as a digital camera, comprising two pattern generators (10,20) generating convergent patterns (14, 24) that are in register on a target object plane. Triangulation between the two pattern generators (10,20) and using superimposed or complementary patterns (14,24) ensures that the hand held device (1) is correctly arranged at a predetermined range and orientation above a document to be captured, such that the document is accurately framed within the field of view of the capture device (1).
