A sender devicestores, in header information about image information, information indicating that attribute information and image data rearranged in sequence, and produces image information by means of storing attribute information and image data in a predetermined sequence. The thus-produced image information is sent to a receiver deviceby way of a network lineWhen receipt of image information is initiated, the receiver devicerefers to the header information, thereby determining presence/absence, in the header information, of information indicating that attribute information and image data are stored in a predetermined sequence. When it has been determined that attribute information and image data are arranged in a predetermined sequence, image data included in the received image information are immediately decompressed, and the thus-decompressed image data are output in the form of a record or display.

Image information processing apparatus, and computer-readable recording medium

A scanner reads image information at read resolution set by a resolution control section and stores the image information in memory An image separation section separates the image information into a first image plane (picture part), a second image plane (text part color information), and a selection image plane (text part forms) for selecting either the first or second image plane. The resolution control section sets optimum resolutions in first to third resolution conversion sections in response to image quality, the original type, the system environment, the image plane characteristics, etc. The three image planes are converted into the resolutions set in the first to third resolution conversion sections The image planes after undergoing the resolution conversion are compressed in first to third compression sections and wrapped in one data format by an image format section

Image processing system, image processing method, image transmitting system, and image transmitting method

Input image information undergoes color conversion processing in a color conversion section , then is separated into first piece of image data, second piece of image data, and selection data in a multilayer data processing section and transmission data in the multilayer data format is output. On the other hand, a 1-layer data processing section prepares transmission data in the normal 1-layer data format from the image information. A color determination section determines whether the input image information is a color or monochrome image. If the image information is determined a color image, a selection section selects the transmission data in the multilayer data format; if the image information is determined a monochrome image, the selection section selects the transmission data in the 1-layer data format. Then, it transmits the selected transmission data through a transmission section

Image transmitting system and image transmitting method

An image processing device includes process means for executing a plurality of jobs each consisting of a given preprocessing and a postprocessing to be executed after execution of the preprocessing; processing amount recognize means for recognizing processing amounts in the preprocessings of the respective jobs; and order decide means, in accordance with the respective processing amounts recognized, for deciding the order to execute the preprocessings or the postprocessings of the jobs.

Image method and apparatus for processing multiple jobs

Image data is input through an image data input means, and stored into an image data storage means on a job basis. The volumes of the respective stored jobs are recognized by a job volume recognition means. A processing priority determination means determines an output processing priority order of the stored jobs based on the recognized job volumes. An interrupt can be generated for a priority job even during output processing of another job according to the output processing priority order.

Image forming apparatus with job priority management of output processing

A job listing section displays four jobs of highest ranks in an output processing order among jobs currently stored. A window L1 indicates that a job shown therein is in a state of 'printing' and windows L2-L4 indicate that jobs shown therein are in an output wait state. To check detailed settings of each job, an operator selects one of the jobs displayed on the job listing section by pressing the corresponding portion with a finger, whereby the selected job is reverse-displayed to inform the operator of the job selection. Detailed settings of the selected job are displayed on a job setting display section (pop-up window).

Image forming apparatus capable of altering a job content and job

A data compression method and device for an image processor such as a digital copying machine. The picture image information is divided into blocks and the blocks are characterized by the variation in density level found within each block. The individual blocks are then encoded. During encoding, the allocation of the chromatic gradation information and the resolution information are varied in accordance with the characteristics of the particular block. The amount of chromatic gradation information and the amount of resolution information are inversely proportional to each other. Because gradation information and the resolution information are varied, the total amount of information in each encoded block is constant. Therefore, the data compression is tailored to the individual requirements of each image block, but the total amount of information in each compressed block is constant. Because the data compression ratio is constant, storage and processing needs for the compressed information can be accurately and easily predicted before the data is compressed.

Data compression method having a fixed ratio of compression for image

An image processing system having data compressing means for compressing image data, data storage means for storing the output data from the data compressing means, data decompressing means for decompressing the compressed image data into the original image data and transferring the decompressed data to an image output terminal, and control means for control the respective means, whereby image data derived from an image input terminal is compressed, stored, decompressed, and transferred to the image output terminal. The image processing system is improved in that the data compressing means or the data decompressing means is provided with bypass means being inserted between the input and output terminals of the means.

The digital image recording system comprises transmission data amount select means for switching, for every page, the color and density of each pixel of the image data as read by the image read means and transferred to the storage means. Format select means switch the output format of the data image output section with every page according to the switched transmission data amount. Job entering sets a copy job, such as the type of documents, page order and the number of copies. Control means control the preset processing unit, the amount of transmission data in the data amount select means, and the output format in the output format select means according to input data in the job entering means.
