摘要： A data compression system is provided having a fixed length coding unit provided before a universal coding unit. The fixed length coding unit detects mode classifications and mode conditions of changing picture elements in a mode detecting unit. Then, the mode classifications and mode conditions are converted to fixed length code words in a code transforming unit representative of, e.g., MH, MR or MMR-type codes. Thereafter, the fixed length code words are predictively coded by the universal coding unit to output compressed data. The present invention is applicable to both character data and picture data. Preferably, the picture data is preprocessed by the fixed length coding unit before both of the character data and picture data are predictively coded by the universal coding unit.

摘要： A color image data processing apparatus processes hue information of picture elements read out sequentially. A chromatic color detection unit is provided for detecting a chromatic color picture element series in a main scanning line having a consecutive succession of chromatic color picture elements including edge picture elements. A replacing unit is provided for replacing the hue value of each picture element of the chromatic color picture element series with a median hue value, the hue value of a picture element located approximately at the center position of the detected chromatic color picture element series. The apparatus may further have an averaged hue value switching unit for switching the hue value of each of the picture elements with an average of the hue value of the picture elements and of other picture elements located in a nearby region.

摘要： In a data compression method based on an LZW coding procedure, a list which defines a sequence of tracing partial strings registered in a dictionary is modified so that a position of a first registered partial string among the registered partial strings in a tree structure of registered partial strings is interchanged with a position of a second registered partial string among the registered partial strings in a state where the first and second registered partial strings extend from an identical node of the tree structure.

摘要： A dictionary searching system retrieves a character string which is described by input reference number and characters from a plurality of mutually different character strings which are registered in a dictionary in correspondence with reference numbers assigned to the character strings. The dictionary searching system includes a dictionary which is made up of an index part for storing in correspondence with the reference numbers a reference number which is assigned to one of character strings which are obtained by adding a character to the character string which is assigned the input reference number and the character which is added to the one of the character strings and a list part for storing in correspondence with the reference numbers a reference number which is assigned to one of character strings having a last character which differs from that of the character string which is assigned the input reference number and the character which is added to the one of the character strings, a reading part for initially reading information from the index part by specifying the input reference number and thereafter reading information from the list part by specifying the reference number which is read from the dictionary, a detecting part for detecting each character which matches the input characters out of characters read from the dictionary and for outputting a result of this detection as a retrieval result, and a deciding part for deciding whether or not a reference number is included in an output of the dictionary and for outputting a result of this detection as a retrieval result, where the reading part, the detecting part and the deciding part operate independently of each other.

摘要： The present invention provides a plurality of code tables such as a high-usage code table and a low-usage code table in an entropy coding unit, and transforms a block-sorted last character string from a block-sorting transforming unit into an MTF code string in an MTF transforming unit. The entropy coding unit switches the code tables at a discontinuous part of the MTF code string to perform entropy coding. In addition, the present invention stores reference lists, whose number is equal to the number of kinds of used characters, in a reference list memory. The MTF transforming unit selects a reference list corresponding to a first character of the block-sorted character string to perform an MTF transformation.

摘要： The present invention relates to a method of and an apparatus for compressing/decompressing data, to improve the compression ratio of sliding-dictionary-type Ziv-Lempel codes. A sliding-dictionary-type data compression method finds a matching character string in a coding character string and in a coded character string stored in a dictionary 101. According to the length of the matching character string, the method chooses a raw data mode that codes the matching character string that must consist of a single character as it is, or a reproduction mode that codes the position and length in the dictionary 101 of the matching character string. The method allocates consecutive numbers to different codes to be prepared under the raw data mode and reproduction mode. The method relates any code prepared under one of the raw data mode and reproduction mode to a corresponding one of the consecutive numbers, codes the number according to a code book, and rearranges the code book to shorten the length of the code of the number.

摘要： A halftone image data compression apparatus includes a first part for detecting a continuous state of pattern data of two successive pixels on a line of a halftone image for N adjacent lines of the halftone image. A second part is coupled to the first part for detecting a run length of the continuous state detected in the first part along a direction of the lines, and a third part is coupled to the first and second parts for subjecting to a universal coding a time-sequential data which is in predetermined processing units. Each predetermined processing unit is made up of one run length which is detected by the second part and corresponding pattern data which are received from the first part while the continuous state is detected for the one run length.

摘要： A noise processing apparatus measures a first potential difference signal, between a first electrode and a second electrode that is used as a reference electrode, and measures a second potential difference signal, between the second electrode and a third electrode that is arranged on the steering unit in the apparatus. The apparatus calculates the difference between the intensities of the first potential difference signal and the second potential difference signal calculated at the predetermined intervals. The apparatus corrects the first potential difference signal or the second potential difference signal by using the calculated difference such that the intensities of the first potential difference signal and the second potential difference signal are canceled out. The apparatus calculates a differential signal indicating the difference between the first potential difference signal and the second potential difference signal by using the corrected potential difference signal, and outputs the differential signal.
