摘要： With facsimile apparatuses wherein color image data is coded, a facsimile on a calling side codes image data by replacing the image data with a codeword indicative of a white run-length or a black run-length, represents color information by combining specific codewords among the codewords and represents image data including color image only by codewords by combining the coded image data and the color information. A facsimile on a called side receives transmitted image data, determines color information represented by a combination of specific codewords among the codewords in the received image data, and outputs image data as specific color image when the color image is determined.

摘要： Image data of a pixel matrix are subjected to orthogonal transformation to coefficient data, which are then quantized with a first quantization table for character image and with a second quantization table for half-tone image. Image data are discriminated as character image data or half-tone image data according to the quantization data. The quantization data corresponding to the discrimination are subjected to entropy coding. Image data can be divided into first processing blocks of m*m pixel matrices and second processing blocks of M*M pixel matrices where M>m. A second processing block includes one first processing block and adjacent pixels. Image data in first and second processing blocks are subjected to orthogonal transformation to coefficient data. Coefficient data of the second processing block indicates whether the image is a character image, a dot image, or a half-tone image, permitting selection of an appropriate quantization table. Image data of the first processing block is quantized according to the selected quantization table and quantized data are coded. In order to discriminate a dot image, two discrimination windows are provided, with the first consisting of coefficient data around the DC component and the second consisting of other data. Orthogonal transform coefficients of image data are calculated, and maximum absolute values in the windows are obtained. An image is discriminated to be a dot image if the first window maximum is larger than a prescribed threshold value and is larger than the second window maximum.

摘要： In a data processor, in order to discriminate the kind of image in a processing block quickly and correctly, image data is divided into first processing blocks of m*m pixel matrices and second processing blocks of M*M pixel matrices wherein M>m. The second processing block includes the data of the first processing block and adjacent pixels around it. Image data in the first and second processing blocks are subjected to orthogonal transform to generate coefficient data. The image type is discriminated as a character image, a dot image or a half-tone image according to the coefficient data of the second processing block and an appropriate quantization table is then selected. Having identified the appropriate quantization table based on analysis of second processing block, image data of the first processing block is quantized according to the thus selected quantization table and quantized data is thereby coded.

摘要： In the electronic sort of a digital copying machine, image data of a document consisting of a plurality of sheets are read and compressed to bi-level data in a memory. The compressed image data are recovered to multi-level data successively. When a plurality of copies of the document are produced, the recovery action is repeated by the number of the copies. In a facsimile machine combined with a digital copying machine, bi-level image data for the automatic reduction transmission are recovered first to multi-level image data, and the density of the multi-level image data is changed for the reduction. Then, the multi-level data are converted to bi-level data for facsimile transmission. In a digital two-color copying machine, multi-level image data of the second color of the two colors to be recorded later has to be synchronized to those of the other in correspondence to the delay of the recording time between the two colors. Then, the multi-level image data of the second color are converted to bi-level data in a delay memory in real time, and the bi-level data are read later from the delay memory and recovered to multi-level data.
