发明名称 Apparatus for improved image formation.
摘要 <p>A device for imaging an object to be photographed or projected comprises a sheet of rigid transparent material having a central portion constituting an object surface. This central portion has opposed edge portions that extend into downwardly projecting side portions that have end edges for supporting the device on a support surface, with the object surface lying in a plane displaced from and substantially parallel to the support surface. The object surface is intended for receiving the object to be imaged. The device is preferably uninterruptedly transparent throughout, and includes a base member interconnecting the end edges of the side portions. This base member has an opaque upper surface to provide a background surface that can either be lit by light sources arranged on two sides of the device, or can be black.</p>
