Patent number: 4386145Abstract: In the forming of microcellular arrays, such as those useful in photography, a closure is positioned to overlie a plurality of microcells forming a planar array. The closure is selectively removed from one set of micro- cells forming an interlaid pattern with a second set of microcells so that the contents of the first set of micro- cells can be changed without concurrently changing the contents of the second set of microcells.Type: GrantFiled: May 6, 1982Date of Patent: May 31, 1983Assignee: Eastman Kodak CompanyInventor: Hugh S. A. Gilmour

Patent number: 4315978Abstract: A color filter array for a solid-state imaging device is disclosed. The color filter array is of the "wash-off" type wherein the individual filter elements are formed by dyeing tiny islands of a dyeable composition. As a barrier layer, the color filter array of the present disclosure uses a photocrosslinkable dye-impermeable polymer. The barrier is coated over a set of filter elements. A method of making the described solid-state device is also disclosed.Type: GrantFiled: March 6, 1980Date of Patent: February 16, 1982Assignee: Eastman Kodak CompanyInventor: Susan E. Hartman

Patent number: 4246338Abstract: This disclosure depicts a new low cost color photographic film assembly which is of the additive type but is of very high speed due to its extremely efficient utilization of available exposure light. The assembly includes a photosensitive layer actinic to light in the entire visible bandwidth of the exposure light for recording intensity variations in light incident thereon. It includes a spectral separation phase structure comprising a pattern of periodically repetitive, wavelength-sensitive phase elements effective to deflect incident light of predetermined different colors in different directions. The phase structure is supported adjacent to the photosensitive layer and spaced therefrom by a prescribed distance which is such that each element of an image formed on the assembly is analyzed into a number of color separation elements segregated on the photosensitive layer. The image is recorded in the layer as a dissected composite of interleaved color separation elements.Type: GrantFiled: March 2, 1979Date of Patent: January 20, 1981Inventor: Sam H. Kaplan
