(under the class definition) Processes wherein a specified process step of retrieving an image, such as by optically projecting the image upon a screen, from an image carrying chemically identified receiver or from an image formed by a chemical reaction. Included procedures for retrieving the image are optical, magnetic, or electrical in nature. Merely viewing the image with the eye is not considered a specified process for the subclass.

1+, for holos:graphic process combined with retrieving the hologram.
5, for image carrying optical mask capable of optically reproducing the image upon a radiation-sensitive product.
20, for the retrieval of image in liquid crystal material.
31, 97, 139, and other process subclasses wherein a latent or visible image is finished or perfected by producing an invisible or visible image and for disclosed but not specified (unclaimed) image retrieval process.
