摘要： A telewriting system has a plurality of telewriting terminals connected with a communication line, each of the telewriting terminals having a display unit so as to display an image thereon. The image displayed on the display unit is changed in accordance with instruction information transmitted via the communication line. A server unit is connected to each of the telewriting terminals by the communication line. The server unit communicates with the telewriting terminals, and has an image memory to store image information corresponding to the image displayed on the display unit. The image information to be stored in the image memory is changed, when the instruction information requesting a change of the image is received from the telewriting terminals, in accordance with the received instruction information. Differential information between the image information before the change and the image information after the change is extracted. The differential information is distributed to each of the telewriting terminals.

摘要： There is provided an image encoding method in a facsimile apparatus or an image filing apparatus as an image communication apparatus. In this method, a color image signal which is expressed by a plurality of color component signals to be encoded is input, the input color image signal is converted into a bit stream signal, and the bit stream signal is encoded by prediction encoding. A parameter for the prediction encoding is changed in accordance with the color image signal to be encoded. The encoding operation is executed adaptively to the color image signal to be encoded. By virtue of bit stream converting the binary color signal, efficient encoding using the color correlation can be executed and an increase in data amount is prevented. By encoding the bit stream signal using a dynamic arithmetic code, a binary color image can be efficiently encoded.

摘要： There is provided a method of processing an input data stream including compressed image data in which an extended tree, characterized by a plurality of words, is developed. Each word is associated with a token set and the words are corresponded with the token sets, respectively, by way of, for example, a look-up table. In practice, a sample word, representing a portion of the compressed image data, is sampled from the input data stream and matched with a selected one of the words from the tree to obtain the token set corresponding with the selected one of the words. The compressed image data portion is then processed in accordance with the obtained token set.

摘要： The present invention provides a method (100) and device (200) for allocating bits to video pictures in a video compression system. A sequence of video frames or pictures is received, and the number of bits used to compress a previously encoded frame and a signal-to-noise ratio for the immediately previously encoded video frame are determined. Rate distortion model parameters are updated. Then, first, second, and third deviations are determined. Finally, the bit allocation for the frame is determined based on the first number of bits used to compress a previously encoded frame, the first deviation, the second deviation, and the third deviation.

摘要： A system and method for facsimile data encoding uses vectors indicating the locations of changing elements along a horizontal scan line. The change vectors are stored in a vector table. The system may use a reference vector table and a coding vector table if CCITT recommendation T.6 two dimensional encoding is used. The system encodes horizontal scan lines using the vectors to determine the location of the changing elements. The value of the reference changing element is easily determined using the vector tables. The system determines the locations of all changing elements on a horizontal scan line before performing any encoding of that particular scan line thus simplifying the encoding process. The system can receive and decode facsimile data to generate change vectors. The change vectors provide a simple mechanism for regenerating the raw data. The change vectors are used to encode raw data into any standard facsimile encoding format, to decode facsimile data, and to interconvert from one encoding format to another without having to convert the encoded data back to raw data.
摘要翻译：用于传真数据编码的系统和方法使用指示沿着水平扫描线的变化元素的位置的向量。变化矢量存储在矢量表中。如果使用CCITT推荐T.6二维编码，则系统可以使用参考向量表和编码矢量表。系统使用向量对水平扫描线进行编码，以确定变化元素的位置。使用向量表容易地确定参考变化元素的值。在执行特定扫描线的任何编码之前，系统确定水平扫描线上的所有变化元素的位置，从而简化了编码过程。该系统可以接收和解码传真数据以产生变化矢量。更改向量提供了一种简单的机制来重新生成原始数据。改变向量用于将原始数据编码成任何标准传真编码格式，以解码传真数据，并将一种编码格式互相转换到另一种编码格式，而无需将编码数据转换回原始数据。

摘要： An image data compression transmission method performs coding of image data into coded data line by line, by a predetermined coding process, adding a synchronizing code to the coded data and generating coded information data by means of a coder. A decoder extracts the synchronizing code from the coded information data, and initializes a decoding process at the receiving side. The decoder determines the validity of the coded information data received from the coder based on the synchronizing code extracted therefrom.If the information data is invalid, then, the decoder performs error processing.

摘要： An image information processing apparatus includes a detector for detecting the move vector of an image of the present relative to that of the preceding field; a circuit for processing, on the basis of the move vector, the image of the present field stored in a field memory; and a residual memory for storing the residual information calculated during the period in which the image data of one horizontal scanning line is inputted. The residual information stored in the residual memory is shunted into a blank area of the field memory during a predetermined interval after the period in which the image data is input. The processing circuit performs a wobble correction to correct any shaking of the image between fields or compresses the data quantity of the dynamic image in image transmission, and the information of one entire picture is processed after being divided into a plurality of blocks, whereby the storage capacity of the residual memory can be widely reduced.
