    摘要: A printer server connectable to a plurality of printers includes a receiver for receiving print data from an external apparatus, a first discrimination unit for discriminating a representation by which the received print data is described, and a selection unit for selecting, from the plurality of printers, a printer to print an image corresponding to the received print data. A second discrimination unit of the printer server discriminates whether the selected printer is capable of processing print data in the discriminated representation. When the selected printer is not capable of processing print data in the discriminated representation, a controller of the printer sever converts the received print data into print data in another representation and transmits the print data in the other representation. The controller transmits print data in the discriminated representation when the selected printer is capable of processing print data in the discriminated representation. The apparatus also includes a status receiver for receiving, from the selected printer, status information indicating that transmitting print data has been printed normally. A status sending unit of the apparatus sends the status information to the external apparatus.

    摘要: According to this invention, when n-value image data is transmitted, data associated with its compression method is transmitted to a reception-side apparatus, so that the reception-side apparatus can perform proper image processing. More specifically, there is disclosed an image transmission method having the following advantages. That is, when a reception-side apparatus can select one of a plurality of image processing methods, it selects a processing method matching with an n-value compression method, and properly reproduces an m-value image. Even when the reception-side apparatus does not have an image processing method matching the n-value compression method of a transmission-side apparatus, that fact can be communicated to the transmission-side apparatus or to an operator of the reception-side apparatus, so that operators of the transmission- and reception-side apparatuses can recognize that a color difference will occur between the transmission- and reception-side apparatuses, and an effective countermeasure can be taken.

    摘要: A window of n.times.m dot is spread over binarized color image data in an original image in order to multi-levelcode the binary data for various image processes with respect to the multi-level-coded data. A binary window is re-arranged to determine the number of dots to be printed within the window for re-arrangement of the dots so as to correspond to the dot positions in the original image. When the number of dots to be printed is within the number of dots in the original image, the dots are rearranged so as to correspond to the dot positions in the original image, while on the contrary, when the number of dots to be printed is increased or decreased, the number of dots is accordingly increased or decreased based on a table, in which the priority of dot arrangement is provided. For these reasons, it is possible to perform various image processes to meet the characteristics of a desired binary color printer even if the original image contains binary color data, thereby allowing a good color image suitable for the binary color printer to be produced.

    摘要: When image data binarized by a density-preserving type multilevel-coding method is to be recovered to multilevel image data, the size of a scanning window which includes as a central pixel point a pixel point to be subjected to multilevel coding is varied and the sums of data values of the binarized image data contained in the scanning windows corresponding to individual window sizes are sequentially calculated in the order of window size. If the sum of the binarized image data value reaches a predetermined threshold for each scanning window size, this window size is determined as a scanning window size for multilevel coding, and multilevel coding is executed. With this process, an optimum window size is determined which is suitable for use in effecting multilevel-coding with high image quality. Since multilevel coding employing the optimum window size is performed, multilevel coding with high image quality and high resolution is enabled.

    摘要: Disclosed is an image interface device connected to a so-called digital copying machine for inputting from and outputting to an external unit, such as a computer system or a communication unit, both multilevel and binary image data. The digital copying machine performs various image processings on the image data output from a scanner for photoelectrically reading an image using a CCD or the like and supplies the processed image data to a printer, such as an ink jet printer, for printing. When the image data is input from the digital copying machine, the multilevel or binary data combined by a multilevel and binary data separating/combining circuit is input through the same data bus controlled by an I/F control circuit. When the multilevel or binary image data is output to the digital copying machine, the data is output through the same data bus, as in the case of inputting the image data. That is, when the multilevel image data is to be output, it is sent from the I/F control circuit to the multilevel and binary data separating/combining circuit and is output as multilevel image data. When the binary image data is to be output, it is output from the multilevel and binary data separating/combining circuit as binary image data.
