摘要： There are described image-recording materials which include an image dye-providing compound comprising a novel naphthol azo cyan dye having a 3-aminobenzoisothiazole moiety. The image dye-providing compound includes a diffusion control moiety such as a hydroquinonyl developer group, a precursor thereof or a thiazolidine moiety and, may be diffusible or nondiffusible as a function of the diffusion control moiety. Image-recording materials according to the invention including those which contain high potential developers such as aminoreductone allow sufficient cyan chromophore to diffuse to the image-receiving layer to provide an acceptable photograph and result in no appreciable reduction of the 3-aminobenzoisothiazole moiety of the novel naphthol azo cyan dye.

摘要： A holographic recording medium comprises (a) an acid generator capable of generating an acid upon exposure to actinic radiation; and (b) a polymer comprising a plurality of high refractive index moieties, a plurality of low refractive index moieties, and a plurality of acid-sensitive linking groups connecting the high and low refractive index moieties. When an interference pattern is formed within this medium, in the light areas of this interference pattern acid is generated by the acid generator and cleaves the acid-sensitive linking groups, thereby causing separation of either the high or the low refractive index moieties from the polymer, and formation of a volume hologram within the medium.

摘要： A light source is disclosed for use as an optical printer illuminating a spatial light modulator to efficiently and uniformly project light onto a photosensitive medium while providing a simpler design of the spatial light modulator in the optical printer. The light source uses light emitting diodes opposed across a light pipe. The light from the light emitting diodes propagates in the light pipe until striking a redirection structure which redirects the light out of lateral surface of the light pipe.

摘要： A bouncing ball scanner is described which is a ball driven in a reciprocal motion for reflecting image-bearing light onto a photosensitive medium. The image-bearing light can be dictated by a computer, in which case the photosensitive medium may be film for a printed output, or the image-bearing light may be reflected from a subject having an image imprinted thereon, and the photosensitive medium may be a charge coupled device where the image is being read into a computer. The bouncing ball scanner comprises a ball being driven in a reciprocal motion by electromagnetic forces acting thereon. The motion of the bouncing ball is substantially linear in each direction so as to allow ease of calculation of ball position thereby ease of knowledge of pixel position on the photosensitive medium.

摘要： The present invention is useful in taking images for identification and other purposes without the requirement of a photobooth, regardless of the background of the image. The original background of the image is replaced with a preselected background. Two IR images with different intensities of IR illumination in the foreground and background regions of the scene, respectively, are compared for light intensity differences between corresponding pixels of the two images to form a mask differentiating between the foreground and background regions of the image. The mask is then applied to a visible light image of the scene and the preselected background is used to replace the original background.

摘要： A system for filtering an image during data compression using a standard JPEG compression/decompression chip typically requires a separate spatial filter external to the chip. The spatial filter is composed of numerous shift registers, flip-flops, multipliers and at least one adder. In contrast, an image filtering system which filters in the frequency domain using the inventive JPEG compression chip modified for filtering in the frequency domain does not require the separate spatial filter and its many components. The modified JPEG chip includes a raster to block converter which converts an image signal into 8x8 blocks, a DCT processor which converts the 8x8 blocks into DCT coefficients, a multiplier which generates filtered DCT coefficients by multiplying predetermined filtering coefficients times the DCT coefficients, a quantizer which generates quantized blocks to a predetermined level stored in a visibility table by quantizing the filtered coefficients, a zigzag scanner which generates a vector having the same number of elements as the quantized blocks, a run-length coder for determining the appropriate run-length according to entropy encoding received from a preloaded Huffman table, and a variable length code packer/unpacker for compressing the entropy encoded vector. A block to raster converter is included to reformat decompressed data.
摘要翻译：在使用标准JPEG压缩/解压缩芯片的数据压缩期间过滤图像的系统通常需要在芯片外部的单独的空间滤波器。空间滤波器由多个移位寄存器，触发器，乘法器和至少一个加法器组成。相比之下，使用修改为频域滤波的本发明JPEG压缩芯片对频域进行滤波的图像滤波系统不需要单独的空间滤波器及其许多分量。经修改的JPEG芯片包括将图像信号转换为8×8块的光栅到块转换器，将8×8块转换为DCT系数的DCT处理器，通过将预定滤波系数乘以DCT系数产生滤波DCT系数的乘法器，量化器其通过量化滤波后的系数将量化块产生到存储在可见度表中的预定水平;生成具有与量化块相同数量的元素的向量的锯齿形扫描器，用于根据量化块确定适当游程长度的游程长度编码器对从预加载的霍夫曼表接收的熵编码以及用于压缩熵编码向量的可变长度代码封装器/解包器。包括块到光栅转换器以重新格式化解压缩数据。
