摘要： A system for performing edge enhancement of mixed low resolution image files employs a binarization and sorting unit to sort data that is indicative of binary data from the mixed low resolution image input file. The sorted binary data is then supplied to a binary data edge enhancement processor for edge enhancement processing. The output from the binary data edge enhancement processor unit is supplied to a data merger unit along with the original image data. The data merger unit determines whether the original image data was part of a gray-scale image. If the data merger determines the original data is part of a gray-scale image, the original data is supplied as the output of the processing system. If the data merger determines that the original data is binary image data, the output from the binary edge enhancement processor unit is supplied as the output of the processing system.

摘要： A data storage system for an electronic color printer which stores data according to the type of information the data represents. When the data represents area fill and image information, the data is stored in the page buffer according to mode A of the invention wherein a plurality of pixels are all defined to have the same color with varying luminance levels. This color is defined in the memory in a uniform color space format. When the data to be stored is representing text or line graphics information, the data is stored in the page buffer according to mode B of the invention. In mode B, two-bit binary values in the page buffer are assigned to each pixel of a multiple-pixel cell. These two-bit values point to additional bytes in the memory block of the page buffer which in turn point to discrete colors in spectrums of 256 colors. Additional data indicates whether the output device is to reproduce the colors by halftoned or non-halftoned techniques. Thus, each pixel within the pixel cell can be printed in a color selected by the color portion of the page buffer. According to mode C of the invention, three separate color maps are defined in binary form by the bit patterns stored in the page buffer memory. Also in mode C, the method used to produce blacks in the output page is specified. By standardizing on the memory allocated to the page and utilizing this memory in different ways according to the nature of the inputted information, the printed page can be accurately stored with a minimum of memory space and without a reduction in perceived printing quality.
摘要翻译：一种用于电子彩色打印机的数据存储系统，其根据数据表示的信息类型存储数据。当数据表示区域填充和图像信息时，根据本发明的模式A将数据存储在页面缓冲器中，其中多个像素都被定义为具有变化的亮度级别的相同颜色。这种颜色是以均匀的颜色空间格式在内存中定义的。当要存储的数据表示文本或行图形信息时，根据本发明的模式B将数据存储在页缓冲器中。在模式B中，页缓冲器中的两位二进制值分配给多像素单元的每个像素。这两位值指向页面缓冲器的存储器块中的额外字节，这又指向256色谱的离散色。附加数据指示输出设备是否通过半色调或非半色调技术再现色彩。因此，可以以由页面缓冲器的颜色部分选择的颜色来打印像素单元内的每个像素。根据本发明的模式C，通过存储在页面缓冲存储器中的位模式以二进制形式定义三个单独的颜色映射。同样在模式C中，指定了在输出页面中产生黑色的方法。通过根据输入信息的性质，分配给页面的存储器的标准化和以不同的方式利用该存储器，可以以最小的存储空间准确地存储打印页面，而不会降低感知的打印质量。

摘要： An improved bar magnet and method of construction, and an improved magnetic core comprising an assembly of such magnets, for use in a processing station of an electrostatographic printing machine. The improved bar magnet is formed of permanent magnet material having magnetic domains therein that are magnetized along epicycloidal curve segments. The external magnetic flux density is improved over that of a conventionally-magnetized magnet. An injection mold for inducing the particular epicycloidal alignment of magnetic domains in the improved bar magnet is provided.
