Method and apparatus for sequential exposure printing of ultra high resolution digital images using multiple multiple sub-image generation and a programmable moving-matrix light valve

摘要

An ultra high resolution photographic printing system that generates and rasterizes multiple sub-images synchronized with positioning coordinates that program a moving-matrix light valve during sequentially timed exposures. Diagonal displacement masking operations prepare a 16384. times.12288 ultra high resolution image for bicubic resampling that generates four unique 4096×3072 intermediate images. These four intermediate images are sieve-sorted based on X and Y modal logic into four unique image sets of 16 unique 1024×768 raster images per set. Each of the 64 unique images sequentially reconstruct a unique "window screen view" of the original high resolution image as dictated by the geometry of the moving-matrix light valve. The moving- matrix light valve is positioned with dual axis micro- stepping motors and leadscrew assemblies. The serial geometry of the light valve RGB elements is sequentially converted to parallel geometry in the printed image. The original high resolution image is seamlessly reconstructed onto photographic media during 192 RGB additive exposures from 64 unique raster images.
