摘要： Although data is transmitted with efficiency by an arithmetic encoding system, the number of carry control signals increases in proportion to the number of consecutive bits "1" s or bytes X`FF` s in a conventional system. In the present invention, an arithmetic encoder 302 `detects the possibility of a carry generated during arithmetic coding operation being propagated beyond at least a predetermined number of consecutive bytes X`FF` s in a supplied arithmetic code 315. When the propagation of the carry is impossible, a carry control signal is inserted into the first 2 bits of the byte other than X`FF` which occurs immediately after the consecutive bytes X`FF` s so as to transmit the presence or absence of a carry. An arithmetic decoder 303 detects the continuation of at least a predetermined number of bytes X`FF` s in the arithmetic code 315, and arithmetically decodes an output value YN316 on the basis of the predicted value MPS317 of the occurrence probability of the output value YN316 to be encoded and the region width Qe of the complementary predicted value LPS. Since the number of total bits of the inserted carry control signals is reduced by this "one-time 2-bits insertion system", the total number of transmitted code bits is also reduced.

摘要： A coding method of a binary Markov information source comprises the steps of providing a range on a number line from 0 to 1 which corresponds to an output symbol sequence from the information source, and performing data compression by binary expressing the position information on the number line corresponding to the output symbol sequence. The present method further includes the steps of providing a normalization number line to keep a desired calculation accuracy by expanding a range of the number line which includes a mapping range, by means of a multiple of a power of 2, when the mapping range becomes below 0.5 of the range of the number line; allocating a predetermined mapping range on the normalization number line for less probable symbols LPS proportional to its normal occurrence probability; allocating the remaining mapping range on the normalization number line for more probable symbols MPS; and reassigning the predetermined mapping range to the remaining mapping range the half of a portion where the allocated remaining range is less than 0.5, when the allocated remaining range becomes below 0.5.

摘要： This invention relates to a coding system and the coding method in encoding information source symbols of an image. When the total number of original information source symbols cannot be known at the decoding site just from the encoded symbols, it is an object to finish the decoding process correctly and decode the symbols equal to the number of original information source symbols.At an encoding site, the total number of information source unit composed of a finite number of information source symbols is placed at the tail of code at the completion of encoding process. For example, at the encoding site, the number of horizontal pels of an image are transmitted in advance as an information source unit and the total number of lines are placed at the tail of code at the completion of encoding process. At the decoding site, the number of decoded lines is counted and decoded up to the number of lines placed at the tail of code. As a result, it is possible to judge the end of information source symbols without missing the total number.

摘要： A coding system comprises the comparing circuit which compares a magnitude of the range on the number line which is allocated to the most probability symbol with a magnitude of the fixed range on the number line which is allocated to the Less Probability Symbol. If the range allocated to the MPS is smaller than that to the LPS, and when the symbol is the MPS, the range allocated to the LPS is generated. If the range allocated to the MPS is smaller than that to the LPS, and when the symbol is the LPS, the range allocated to the MPS is generated. By the system, a coding efficiency is improved especially when a probability of occurrence of LPS (Less Probability Symbol) is approximate to 1/2.

摘要： Encoding and decoding devices which are capable of increasing the encoding and decoding speed. In arithmetic encoding, there is a possibility of encoding with high efficiency which is very close to the entropy of the information source, but the encoding and decoding time is generally longer than that in another encoding systems such as an MMR encoding system. For example, in a standard facsimile equipment, about 1.3 sec is required for encoding the picture information in an A4-size copy. In prediction encoding, a memory for storing the past reference symbols and the predicted values therefor is necessary for prediction. Since the memory capacity is generally large, a large-capacity RAM is used. The encoding time is therefore greatly dependent on the access speed of the RAM. In the present invention, a high-speed register for storing the predicted value for a special symbol pattern is provided separately from the RAM so that the predicted value of the special symbol pattern is read from this register, thereby enabling high-speed encoding.

摘要： An input gray-scale image is converted to a bilevel output signal by an image-processing apparatus with two binarizing circuits: one employing a uniform threshold and the other a dither matrix. The outputs of these circuits are selected for each pixel by deciding whether the pixel is a bilevel pixel or a gray-scale pixel. The decision is based on the maximum and minimum gray levels in a block of pixels centered on the pixel in question. Images having both bilevel and gray-scale parts can thus be binarized with clean reproduction of black-white edges.

摘要： An image data transmission system includes mobile transceivers having memories storing image data that is organized in sequential blocks. The mobile transceivers sequentially pass by a stationary transceiver and pause proximate the stationary transceiver. While pausing, a mobile transceiver transmits a block of the image data to the stationary transceiver, which receives and stores the transmitted data. Data transmission is interrupted by movement of the formerly pausing mobile transceiver. The stationary transceiver transmits a pointer signal to a paused mobile transceiver indicating which blocks of image data have been stored in the stationary transceiver so that the mobile transceivers transmit the blocks sequentially until all blocks have been received and stored by the stationary transceiver. The apparatus may be employed in a mass transit system, such as a subway or commuter train, in which the mobile transceivers are mounted in train cars and the stationary transceiver is located at a station. The image data may be used to illuminate electronic displays in the station each time all of the blocks of data have been transmitted to and stored in the stationary transceiver. Thus, the vehicles containing the mobile transceivers function as a transmission line and can provide continually updated data for news and advertisement displays.

摘要： Binary 0's and 1's from picture elements in each line are counted with respect to each mode determined by adjacent picture elements to form symbol patterns determined by both the counts and the information content of a memory. Each pattern is encoded into a code word to be transmitted having a bit number determined by the arrangement of binary symbols included in it. Also the code words can be transmitted on the basis of address numbers of picture elements, starting with the output from a coder associated with a mode having the two-valued signal with the least address number.
