Abstract: A sheet preview system generates a print preview of a sheet that has a layout specifying a position and orientation for each page. To generate the print preview of the sheet, the sheet preview system displays a representation of the sheet that includes an image of each page of the sheet. The sheet preview system positions and orients the images in accordance with the layout of the sheet. The sheet preview system then displays in association with each displayed image of a page the page number of that page. The sheet preview system may orient the page number of the page in accordance with the orientation of the page.

Abstract: A camera, together with a light source, is pointed by means of a mirror system at a projection surface which lies on the apparatus or adjacent to it. Transmitted light pictures, such as slides, can be placed in front of the light source, the said pictures thus being reproduced on the projection surface and being recorded from there. Instead of such projected images, it is possible to illuminate and record articles. Connecting two pieces of apparatus with one another, each apparatus having a monitor, provides a universal video telephone.
