摘要： A data encoding apparatus, applicable for example to a facsimile apparatus, increases the degree of image data compression that can be achieved by a variable length encoding scheme, by limiting the maximum amount of data outputted from the encoding apparatus for each scan line to the amount of unencoded image data in a scan line. Generation of increased amounts of data in the case of certain types of image content, as a result of the variable length encoding, is thereby eliminated with a consequent increase in encoding efficiency.

摘要： A method for disconnecting character strings from compressed image data comprising the steps of: scanning data blocks representative of the photographic/graphic data portion to detect the initial and last y-coordinates of the continuous text data portion, accumulating the number of pixel lines representative of the text data portion, and calculating the character string width upon detecting a profile line. Based on the accumulated number of pixel lines representative of the text data portion, a discrimination is made as to whether a character string is connected to the scanned block. When a character string is connected only to one of left and right sides of the data block, the connected character string is disconnected forcedly by creating a new block corresponding to the character string, based on the position information of each text data portion. In accordance with the present invention, it is possible to improve the accuracy in extracting each data portion and thus the reliability in the acknowledgement of the document.

摘要： A run length encoder for converting bi-level video image data made up of white and black representative pixel values to a run length code to be used by a vector processor including a transition detector for detecting the transition of inputted image data values from either white to black or black to white. The inputted image data are addressed along each scanned line. At every white to black transition, the pixel address is stored in memory. The number of continuous black pixels following this first transition is counted until a black to white transition is detected. The resulting count value corresponding to each stored address value for each black "run" is also stored in memory, wherein these stored values represent the run length code of the video image data for use with the vector processor.

摘要： In a facsimile data processing apparatus, printer code, including a line pitch amount control command and character codes are received from a host computer. The character codes are converted into image data and the image data is converted into transmission code such as modified Huffman code. The line space is directly converted into the transmission code, in the form of white code, without the conversion into image data. The line space varies according to the line pitch amount control command by changing the amount of the white code to be added.

摘要： Binary image data is converted to CCITT standardized coded data by utilizing two barrel shift registers for selecting a window of image data from a reference line and from a coding line, two color changing detectors for converting the image data in a window to color changing codes, and one specially designed state machine for generating facsimile coded data from those color changing codes. The state machine operates on color change location data for the selected window to generate intermediate codes. The intermediate codes are then translated to an output format such as the CCITT standard.

摘要： In order to increase decoding speed of two-dimensionally encoded facsimile data, changing pixels a.sub.0, a.sub.1, a.sub.2 and b.sub.1 (defined by CCITT) on a decoding and reference lines are detected, and the address of b.sub.1 is stored into a reference line address memory. The address of b.sub.1 is compared with the address of a.sub.1 during the vertical mode, and if a.sub.1 >b.sub.1, the address of a.sub.1 is stored into the reference line address memory. During the horizontal mode, the addresses of b.sub.1 and a.sub.2 are compared. If a.sub.2 >b.sub.1, the address of a.sub.2 is stored into the reference line address memory.

摘要： One-dimensional compression is effected by addressing a first ROM (62) with information in respect of the length and the type of run. One-dimensional decompression is effected by addressing with the compressed code, a second ROM, bearing the information in respect of the runs and the length of the code. That is provided by a shift register controlled by a logic unit capable of recognising a group of least significant bits, to permit additional shifting of the register, and addressing of the second ROM with a bit number less than the maximum length of the codes. For two-dimensional compression or decompression, there is provided a pair of RAMs for temporarily storing a reference line which, together with the current line, actuates a logic means (38), for controlling coding and decoding of the latter. For compression of the medium tones, besides the runs of the two colors, coding is effect in respect of the runs of the alternations of the two colors defined on the basis of the color of the initial pixel, and the type of the successive run is defined. Besides the coding and decoding for two-color images, the two ROMs also carry the coding and decoding for images with the half tone. Finally, the apparatus comprises an archive memory which can be connected to the compression module for archival storage of the images with the maximum degree of compression. By instead connecting the decompression module between the archive memory and the compression module, the image can be transmitted with a type of compression compatible with the receiving station.
摘要翻译：通过用关于运行的长度和类型的信息寻址第一ROM（62）来实现一维压缩。通过用压缩代码寻址来实现一维解压缩，第二ROM支持关于代码的运行和长度的信息。这由由能够识别一组最低有效位的逻辑单元控制的移位寄存器提供，以允许寄存器的附加移位，以及以小于代码的最大长度的位数寻址第二ROM。对于二维压缩或解压缩，提供了一对用于临时存储参考线的RAM，该参考线与当前行一起致动逻辑装置（38），用于控制后者的编码和解码。对于中等音调的压缩，除了两种颜色的运行之外，编码对于基于初始像素的颜色定义的两种颜色的变化的运行而言是有效的，并且连续运行的类型是定义除了双色图像的编码和解码之外，两个ROM还对具有半色调的图像进行编码和解码。最后，该装置包括可以连接到压缩模块的存档存储器，用于以最大程度的压缩存档图像。通过替代地将压缩模块连接在归档存储器和压缩模块之间，可以使用与接收站兼容的压缩类型来传输图像。

摘要： The present invention is featured, in the transmission of pixel (picture element) signals grouped into blocks defined in a series of pixel signals, by sending a control signal instead of said pixel signals when the pixel signals contained in a block are all white signals or sending pixel signals after modulation when black signals are present in said block thereby compressing the time required for transmission, also by selecting the maximum amplitude of said control signal larger than the maximum amplitude of said modulated pixel signals thereby enabling identification of said control signals from said pixel signals, and by sending, when the final black pixel signal in a black signal containing block is followed by consecutive white pixel signals, a control signal instead of such white pixel signals thereby achieving further compression of the transmission time.
