摘要： A method for enhancing the edge of a halftone image includes steps of: forming an analysis window with a central pixel and neighboring pixels; quantifying the pixels to get a halftone table; assigning a designated value to each pixel for generating a halftone result; and comparing the halftone result with an edge enhancement table. The edge enhancement table includes a plurality of dotting commands and a plurality of dot tables. The dot tables correspond to the dotting commands so that when a dot table is conformed to the halftone result, a correspondent adjustment of halftone table is taken.

摘要： Method and apparatus to enhance laser printer speed and functionality including a general purpose computer, a laser printer, and a modified laser printer font cartridge, comprised of a 21-bit wide address bus, a read-only data bus, a page register, an address counter, a data counter, a font ROM module, an address-to-data converter, and a co-processor. The address bus is coupled to the laser printer and carries either address information to access locations in the co-processor or the font ROM, or data to be input to the co-processor. When the address bus carries only address information, the quantity of accessible memory locations is increased by mapping the contents of the page register with the bit code carried by the address bus. Thus, font pattern data may be read from the font ROM memory location represented by the combination of the page register contents and bit code carried by the address bus. However, if special information is loaded into the data counter, then the information carried by the address bus is actually data to be written to the co-processor. The data is transferred from the address bus, by the address-to-data converter, to the location in the co-processor represented by the combination of the contents of the page register and the address counter. The data bus is coupled to the laser printer and carries either processed font pattern data from the co-processor, or unprocessed font pattern data from the font ROM to the laser printer.
摘要翻译：提高激光打印机速度和功能的方法和装置，包括通用计算机，激光打印机和修改的激光打印机字体盒，包括21位宽的地址总线，只读数据总线，页寄存器，地址计数器，数据计数器，字体ROM模块，地址到数据转换器和协处理器。地址总线耦合到激光打印机，并且携带任一地址信息以访问协处理器或字体ROM中的位置，或者输入到协处理器的数据。当地址总线仅携带地址信息时，通过将页寄存器的内容与由地址总线承载的位代码进行映射来增加可访问存储器位置的数量。因此，可以从由页面寄存器内容的组合和由地址总线承载的位代码表示的字体ROM存储器位置读取字体图案数据。然而，如果将特殊信息加载到数据计数器中，则由地址总线携带的信息实际上是要写入协处理器的数据。数据通过地址到数据转换器从地址总线传送到协处理器由页寄存器的内容和地址计数器的组合表示的位置。数据总线耦合到激光打印机，并将来自协处理器的处理后的字体图案数据或从字体ROM的未处理的字体图案数据传送到激光打印机。

摘要： An exposure correction method for digital images first computes a gray-level histogram of an image. Then determine whether the exposure of the image is normal from the gray-level histogram, thereby determining an exposure threshold. The central region of the image is extracted to find an average brightness Iave. The average brightness Iave and a destination brightness Idest are used to determine an adjusting curve y=f(x). The brightness channel is adjusted according to a constructed correspondence table. Therefore, the image processing effects are enhanced even though the processing time is reduced.

摘要： A rapid white balance method for color digital image is disclosed. This method is applied to RGB color regions in an image. First, the image is divided into several blocks to obtain the G parameter, then the averaged R and B parameters of each block, thereby obtaining the R and B parameters of the whole image. Using the R and B parameters, the method obtains an R gain and a B gain. Finally, the image is adjusted. The method only uses one RGB value for each pixel. The processing time is reduced, while the quality of the image is increased.

摘要： Edge enhancement method and apparatus for dot matrix devices wherein a group of gradient mask matrices are applied to a "current matrix", wherein a TBAP (To Be Adjusted Pixel) is surrounded by neighboring pixels, to determine if the TBAP is at a location where a change of brightness occurs. From this matrix operation, a conclusion is derived as to the existence or non-existence of an edge and the direction of the brightness change. The current matrix and a predetermined number of previously evaluated and yet to be evaluated pixels are then compared to a set of reference bit patterns which depict possible segment changes to be corrected. If the result indicates that the TBAP is on an edge of a changing edge segment, a corresponding code will be generated to modify the TBAP to enhance the smoothness of a segment transition. In the case of an electrophotographic printing machine, the specific code will change either the location or the size of the TBAP; whereas in the case of a monochrome screen display, the specific code will change the intensity of the TBAP.

摘要： This specification discloses a system of using a neural network to distinguish text and pictures in an image and the method thereof. Using the knowledge of text recognition learned by the neural network in advance, images data of color brightness and gray levels in an image block are processed to generate a greatest text faith value. The system determines the text status of the image block by comparing a text threshold with the greatest text faith value. If the greatest text faith value is larger than the text threshold, then the image block is determined to contain text pixels; otherwise, the image block contains purely picture pixels. This achieves the goal of separating text and pictures in an image.
