Abstract: An image projection system includes an image projection device for projecting a light image onto a wall, ceiling or other designated surface. The image projection device includes a housing within which is disposed separately located light sources. The housing further includes a slot for receiving several image slides. Each image slide has multiple, separated, slide image patterns thereon and each slide image pattern is in a different location on the image slide. Each of the light sources is disposed in a light chamber such that light from one of the light sources projects through only one of the separated image patterns on the image slide. Light from light sources passing through respective slide image patterns can then intersect to project multiple superimposed images on an image viewing surface. Furthermore, an electronic controller controls the light intensity and light timing of each individual light source.

Abstract: An image projector that drops into the accessory slot of a luminaire and projects high quality images printed on plastic slides in full color and photographic detail for extended time periods without heat degradation. The projector comprises a cooling fan, infrared and ultraviolet light filter means, and an inexpensive and removable slide assembly comprising a plastic image slide, a protective film slide and at least one mounting plate. The cooling fan is combined with layered, reflective filters to create a protected environment for the plastic image slide to survive the extreme heat at the gate of today's efficient luminaires. The plastic image slide is created on a plastic sheet using conventional computer printing technologies.

Abstract: An image scanning device is provided with simplified operation. A document holder has reference marks and/or a positioning frame so a document, such as a film or film slide, can be repeatably placed in an accurate position on the document holder. The document can be pressed between two flat plates of transparent material on the document holder to keep the document flat. The image scanning device has a door that need not be manually opened or closed. The document holder is inserted into the image scanning device through the door and is accurately mounted to a movable stage. The stage contacts the document holder so the document holder is positioned on the stage in the same position every time the document holder is mounted to the stage. The stage can also be positioned such that the stage is fixed to a case containing the image scanning device. By fixing the stage to the case, damage to the stage and other support devices is avoided during shipping or transport.

The light table has a tray mounted thereon for movement into mutually orthogonal directions parallel to the plane of the light table and supported by a counterweight, the tray receiving a planar slide holder whose slides and windows are alignable with a window in the light table. A projection lamp is located at the front side of the window while the projection optics are located at the rear side of the window.

Abstract: Apparatus is described for use with a projector which can direct light substantially horizontally through a projection location and which can project the image of a slide thereat onto a screen, which enables the projection of the images of slides contained in a flexible storage sleeve of a type which is normally stored in a three-ring binder with the slides coplanar. A carrier has a pair of slightly spaced walls for receiving the storage sleeve between them, the walls having rows and columns of transparent regions corresponding to the location of the slides in the sleeve. A holder slidably supports the carrier so one of its slides lies at the projection location for projecting the image onto a screen. The holder allows the carrier to be slid horizontally to show any of the slides in a row of slides on the sleeve, and allows the carrier to be moved vertically to show the slides on another row of the sleeve.

Abstract: A test pattern projector built into a color television camera, for adjusting the camera to desired conditions in order to attain a favorable quality of image immediately before use. A test pattern chart is illuminated with an illuminating light of an adjusted color temperature, forming an image of the test pattern chart on an image pickup apparatus. The color temperature adjustment of illuminating light emitted from a light source is effected by using a color temperature conversion filter and a color compensating filter both disposed in front of the light source. An interference filter or an absorbing filter with a wedge shape in cross section can be employed as the color compensating filter. The color correction depends, in the former, on the inclination thereof relative to the optical axis and, in the latter, on the thickness thereof intersecting the optical path.
