Relief images are prepared in a sheet of silver having a surface of silver bromide.

In a method and apparatus for two-dimensional parallel data processing, a pattern of information to be analyzed is reproduced in a field of bi-stable information bearing elements. The pattern is processed by comparing the states of the six nearest neighbor elements around each element with at least one of the possible patterns of states of said six neighbor elements, without regard to correspondence of rotational orientation of the actual pattern with the possible patterns, and fixing each eleme...

Improvements in a full resolution image A are effected with an economical use of computer processing equipment and time by determining a field of improvement functions derived from processing a coarse representation of the original full resolution image. The coarse representation B is subjected to lightness field analysis to obtain an improved coarse image C, from which a coarse improvement field D is extracted by subtracting the original coarse representation. To obtain a full resolution improv...

The production of an improved image by first producing an imagewise metallic silver image in a photosensitive layer and then treating the layer with a substance which decomposes at the metallic silver to result in a superimposed vesicle image. The vesicle image increases the density of the original silver image to provide high sharpness. The process is carried out using a silver salt emulsion in a binding agent to provide the metallic silver upon photographic processing. The binding agent is a s...

Multi-colored images are built-up from thermoplastic, separation negatives obtained for example on a laser printer. Colored positive separations are obtained by applying a colored, transferable non-thermoplastic layer on a carrier over each thermoplastic negative separation, subjecting the assembly to heat and pressure, and peeling apart the assembly whereby colored non-thermoplastic positive images remain on the carrier sheet. Each colored non-thermoplastic positive separation in turn is then t...

For reducing speckle in echo signals derived from reflections of pulsed coherent waves, the echo signals are subjected to amplitude and phase/frequency demodulation and the resultant amplitude and phase/frequency data are multiplied to generate an image signal. Selective control of the multiplication process may be provided in accordance with signal amplitude and/or signal-to-noise ratio.

Described herein is a method of scanning an image formed on a color filter array film using a monochrome scanner. The image forming layer of the film is chosen so as to have a maximum density which occupies a small portion of the dynamic density range of the scanner, the excess density range of the scanner being used to decode the colors of the color filter array.

An image producing system is provided which comprises a carrier material of fabric, paper, a felt or fabric pad impregnated with a color former solution, comprising a weakly volatile high boiling organic solvent having dissolved therein a color former and a color former deactivating substance, wherein the color former is an azo compound and a substrate which has incorporated therein or possesses at least one surface which is at least partially coated with a color former activating substance or s...

An image producing system is provided which comprises a substrate having printed on at least a portion of a surface thereof an ink containing a neutral or substantially neutral ink vehicle, a liquid organic base and a color former, and which system also comprises a carrier material impregnated with a solutions of an organic acid in a weakly volatile high boiling solvent.

Transfer images or decalcomania pictures, and method of producing the transfer images or pictures. The transfer pictures can be made from a roll of material or from sizes of material of flexible paper or such plastics which connected with a separating layer, which is coated with a transfer lacquer, which in the composite of the materials are imprinted on the front side, and upon occasion on the rear side with different pictorial motifs, by liquid printing colors, and which in the combination of ...
