摘要： This invention proposes to transcode the compressed image. The transcoding includes decoding differential pulse code modulation DC frequency components of plural image blocks, then partitioning the image into plural image cells (320). The transcoding then recodes DC frequency components of the image blocks in differential pulse code modulated format (303). The transcoding then extracts and stores the Huffman tables from the image data (304). The transcoding then identifies image blocks by a block count (305) and recodes these image blocks into corresponding image cells (306). This transcoding permits pseudo-random access to the data permitting efficient image transformation. By using this format, in most cases a pixel is decoded only once in the entire image transformation process. This transcoding would enable image transformations in printers whose memory is insufficient to store the entire decompressed image.

摘要： The present invention provides a method of ameliorating the effects of misalignment between modulator arrays, and a system using the same. The ability reduce the effects of misalignment allows multiple, smaller, more cost effective arrays to be used instead of one large array. This can reduce the manufacturing costs of the array, especially arrays that are produced using semiconductor manufacturing processes such as the digital micromirror device. To avoid visual artifacts caused by the misalignment of two or more modulator arrays 1702, 1704, the individual arrays 1702, 1704 are optically overlapped and a portion of the image 1706 is generated by both arrays 1702, 1704. A breakpoint is chosen between two pixels in the overlapped region 1706 at which to abut the images from each of the modulator arrays 1702, 1704. The breakpoint is changed each row of pixels to minimize the detectability of any visual artifact caused by misalignment between the modulator arrays 1702, 1704.
摘要翻译：本发明提供了一种改善调制器阵列之间的未对准的效果的方法和使用其的系统。降低失准影响的能力允许使用多个，更小，更具成本效益的阵列而不是一个大阵列。这可以降低阵列的制造成本，特别是使用诸如数字微镜器件的半导体制造工艺制造的阵列。为了避免由两个或更多个调制器阵列1702,1704的未对准引起的视觉伪像，各个阵列1702,1704被光学重叠，并且图像1706的一部分由阵列1702,1704产生。在两个像素之间选择断点在与重叠区域1706相邻的位置处，以与每个调制器阵列1702,1704的图像相邻。每个像素点改变断点，以最小化由调制器阵列1702,1704之间的未对准引起的任何视觉伪影的可检测性。

摘要： An improved method for time delay and integration printing for gray scale. A gray scale represented by a bit pattern is provided for time delay and integration printing onto a photosensitive substrate. The pattern (12) is rotated about the light intensity cycle of the light source such that microbands in the final image are minimized or eliminated and sent to a spatial light modulator (10) for transfer to a printing substrate.
