An image processing apparatus includes an image reader, an input operation unit including a display, an interface configured to receive, from an external medium, setting information for processing of an image read by the image reader, and a controller. The controller is configured to control the display to display a first setting screen for processing the image when the setting information is not received from the external medium and to control the display to display a second setting screen for processing the image when the setting information is received from the external medium. The second setting screen indicates that an operational setting designated by the setting information has already been set on the image processing apparatus.

An image forming apparatus having a reading unit which reads image information on an original, a first compression unit which compresses the image information into compressed image information, a first encoding unit which encodes the compressed image information, an interface unit which acquires printing information in a page description language from exterior, a generating unit which generates printing image information on the basis of the printing information, a second compression unit which compresses the printing image information into compressed printing image information, a second encoding unit which encodes the compressed printing image information, a decoding expansion unit which decodes and expands the encoded compressed image information and the encoded compressed printing image information, and a forming unit which forms an image onto a recording medium on the basis of the image information and the printing image information which have been decoded and expanded.

Image forming apparatus and image forming method

An image forming apparatus has a preparation function of preparing print data for every page corresponding to inputted code data, a memory area for storing the print data prepared by the preparing function, a printer function of performing printing corresponding to the print data stored in the memory area when there is any print data stored in the memory area, or corresponding to the print data prepared by the preparation function when no print data is stored by the storage function, and a control circuit for comparing a data amount of the print data with an empty capacity of the memory area and for controlling the memory area so as to store the print data when the empty capacity is larger than the data amount or for controlling the storage area so as not to store the print data and controlling thereafter each means such that the data amount is not compared with the empty capacity when the data amount is smaller than the empty amount.

A disk array apparatus employs portable optical disk. The apparatus determines whether a file should be concentrated recorded in a single optical disk or distributively recorded among a plurality of disks, in accordance with the amount of that file. With respect to an often-accessed file, the apparatus records it among a number of optical disks, or makes a duplicate copy of the file and stores the duplicate copy in an optical disk different from the optical disk containing the often-accessed file. Since the often-accessed file is handled in this manner, the apparatus enables efficient file management and permits a file to be accessed at high speed.

An external device for sending data can execute write access by the control of a buffer memory management unit and an access control unit only when an empty area is present in a buffer memory area of a memory designated by an area designating unit of the buffer memory management unit. Another external device for receiving data can execute read access by the control of the buffer memory management unit and an access control unit only when data is stored in the buffer memory area. The external devices with different processing speeds can transfer data asynchronously.

Data transfer apparatus

When image information is to be transferred between processing units having different image information forms, e.g., the pixel width and plane width of image information, the image information is converted by a reformatting unit using the form attribute information of a transfer source and that of a transfer destination. With this operation, a long processing time is not required to transfer image information between arbitrary processing units having different image information forms, e.g., the pixel width and plane width of image information, and there is no need to impose limitations on the types of forms which can be processed on one apparatus, thus enabling high-speed processing and realizing a flexible system.

First parameters such as a main scanning repetition count, a subscanning repetition count, and the like are calculated in accordance with an instructed rotation angle. An arithmetic content according to the instructed rotation angle is read out from a memory for storing arithmetic contents for determining second parameters according to rotation angles, and the second parameter is calculated based on the readout arithmetic content. Main scanning and subscanning addresses are generated in accordance with the calculated second parameter and the detected first parameters. Whether or not the generated subscanning address is changed is detected. If it is detected that the subscanning address is changed, a subscanning address is generated using a subscanning step count upon a change in address as the second parameter. The input image is stored in the bit map memory in accordance with the generated main scanning and subscanning addresses. In order to generate addresses for a rotated figure free from gaps, the Bresenham's line generation algorithm is used in the main scanning direction, and subscanning addresses (start points of lines) are generated in accordance with an angle.

An image information processing apparatus includes an image memory having a page memory area for storing image information and a FIFO memory area which is provided integrally with the page memory and a read/write operation of which is controlled independently of the page memory area. Coded image information supplied from a recording unit is transferred to a codec circuit through the FIFO memory area and decoded by the codec circuit. The decoded information is stored in the page memory area.

Image information processing apparatus

An image processing apparatus comprises a memory for storing image data and character data, a display for displaying data stored in said memory means, and a three-address generating section for generating three addresses for addressing the memory to execute simultaneously two processings, one of which transfers the data from the memory to the display and the other of which writes character information into said memory.
