摘要： Non-real-time decompression of stored image data permits an unlimited amount of image data to be rendered with a limited amount of available memory. When the memory available to a display list (18) is filled with image data, it is rendered into a band buffer (44) and then compressed into a compressed band buffer (47), to free up the memory used by the original display list entries. Additional entries are then entered in the display list. After the remaining entries have been captured in the display list (18), the information stored in the compressed band buffers (47) is decompressed and stored in the uncompressed band buffer (44). The additional image data in the display list is then rendered, and combined with the previously rendered data in the uncompressed band buffer (44). After the rendering is completed, the contents of the uncompressed band buffer is again compressed into the compressed band buffer format. This procedure can be continually repeated until all of the image data has been rendered into respective bands, and the page of data is complete.

摘要： The present invention is directed to systems and methods for compressing image data while at the same time, the speed of compression, the compression ratio (that is, reduced memory requirements) and the perceptibility of the decompressed image, even when the image data is compressed without segregation into its scanned and non-scanned components. Exemplary embodiments achieve such improved perceptibility regardless of whether the images are monochrome (having varying grey scale values) or color. In addition, improved perceptibility is realized in a manner which permits image data including scanned and/or unscanned images to be compressed in real-time.
摘要翻译：本发明涉及用于压缩图像数据的系统和方法，同时压缩速度，压缩比（即，降低的存储器要求）和解压缩图像的感知性，即使当图像数据被压缩时没有隔离到其扫描和未扫描的组件。无论图像是单色（具有变化的灰度值）还是颜色，示例性实施例实现这种改进的感知性。此外，以允许包括扫描和/或未扫描图像的图像数据被实时压缩的方式实现改进的感知性。

摘要： A system for processing image data determines output values which produce an accurate reproduction of source device images in a destination device. The system utilizes interpolation processing in concert with a single-entry cache memory wherein, for a given source input value, a source device image space region is determined, which region contains the source input value. A look-up table is utilized to determine a corresponding destination device image space region, data for which is stored in the single-entry cache. Interpolation is performed using the cache data and the source input value. Subsequent input values are analyzed to determine whether the cache data previously stored may be utilized again.
摘要翻译：用于处理图像数据的系统确定在目的地设备中产生源设备图像的准确再现的输出值。该系统利用与单入口高速缓存一致的内插处理，其中，对于给定的源输入值，确定源设备图像空间区域，哪个区域包含源输入值。使用查找表来确定对应的目的地设备图像空间区域，其数据被存储在单条目缓存中。使用高速缓存数据和源输入值执行插值。分析随后的输入值以确定先前存储的高速缓存数据是否可以被再次利用。
