A silver halide imaging element is disclosed that is capable of providing a sharp image with silver halide grains still present following imagewise exposure and development. This is achieved by choosing a dispersing medium for the silver halide grains comprised of an organic vehicle and, dispersed therein, titanium dioxide particles having an average size of less than 0.1 micrometer accounting for at least 10 percent by weight of the dispersing medium. The elements are useful for optical printing or scan image retrieval without fixing. The elements can be used for providing black-and-white photographic images, radiographic images or dye images.

A media for restricting the copying of a document utilizing one or more microdots that are embedded in said document for providing a non-visual, but machine detectable mark or marks. The detected means for detecting the presence of one or more microdots in said document inhibits a copy machine from copying the document.

Copy restrictive documents

A color-negative photographic print medium for restricting the copying of an image in the medium utilizing a pattern of removable color-subtractive microdots depth-wise positioned anywhere within a transparent protective overcoat and a support layer which supports at least one image-forming layer is disclosed. The microdots are undetectable by the unaided eye, but detectable by copying machines programmed to prevent copying when microdots are detected.

A viewer having a collapsed condition and a viewing condition. The viewer includes a front and rear wall formed of a flexible material and joined together at their top and bottom edges. The front wall includes a pair of images disposed on the interior surface of the front wall, while the exterior surface includes a reflection print. The rear wall includes a pair of viewing apertures having lenses in optical registration with the pair of images. A middle wall is disposed intermediate the front and rear walls and is joined together with the rear wall at their bottom edges. The middle wall includes at least one aperture in optical registration with the pair of images. The front and rear walls move between the viewing condition wherein the front and rear walls flex to define convex curves and the pair of images are viewable through the pair of viewing apertures, and the collapsed condition wherein the interior surfaces of the front and rear walls abut the middle wall.

A still picture camera for capturing images when film is alternately advanced from any one of three film cassettes into a common film gate for a controlled exposure by light passing through an objective lens and shutter, the camera comprising a camera body, an objective lens for forming an image, a shutter for controlled admission of light, a film gate for defining the area of exposure of one frame of photographic film, three film cassette chambers mounted in a rotating turret each accepting a film cassette, a turret rotation mechanism, a film advancement mechanism, and one film spooling chamber for alternately receiving film from any film cassette.

A system for restricting the copying of a color-reversal document having one or more microdots embedded in the color-reversal document. The system of detecting the presence of one or more of the embedded microdots and controllably disabling a copy machine to prevent it from copying the color-reversal document when at least one microdot is detected.

A cartridge holder for a film cartridge to be used with a camera of the type having a built-in support socket, such as a tripod socket, is characterized in that the cartridge holder includes a fastener configured to be received in the support socket to attach the cartridge holder directly to the camera.

A media for restricting the copying of a color-reversal document utilizing one or more microdots that are embedded in the color-reversal document for providing a non-visual, but machine detectable signal. By detecting the presence of one or more microdots in the color-reversal document, a copy machine is controllably prevented from copying the color-reversal document.

An apparatus for creating copy restrictive media is disclosed comprising a linear array (20) comprised of at least two spatially distributed light sources (22) and an aperture mask (28) for forming two or more micro-light sources from the light sources (22). An optical element (32) focuses light from the micro-light sources onto a media (40) moving relative to the linear array (20). An encoder (16) turns the light sources (22) on and off at regular intervals relating to movement of the media (40).

Apparatus for creating copy restrictive media

A system and associated method for restricting the copying of an image document that contains an image of arbitrary and undetermined character that is formed in or on a document medium having a predetermined pattern of microdots. One embodiment of the system includes a copy machine and associated software that scans for the presence of microdots in an image document and if present prevents the copy machine from making a copy. The microdots are of such a size that they are not visible to the unaided eye, but when machine scanned their presence is sensed.
