An image input section pre-inputs an image. A temporary storage section temporarily stores the image input by the image input section. An attribute control section controls at least attribute information of the input information temporarily stored in the temporary storage section. A selection section permits a user at the origin of image request to select a desired one of already stored images stored in the temporary storage section in accordance with the attribute information controlled by the attribute control section. An image transfer section reads out the desired image selected by the selection section from the temporary storage section at the time of the request by origin of the image request and transfers the desired image to the origin of the image request via a network.

Image information input apparatus

A plurality of data storage media which are constructed in a hierarchical structure of a plurality of levels having different access times and have different access information items are provided, a data storage medium into which data is to be stored is selected according to the access frequency of data, and data is stored according to the result of selection. At the time of data relocation between the data storage media of different hierarchies or between the data storage media of the same hierarchy, one of a plurality of relocation measures is selected according to the characteristics of the data storage media and the characteristic of data to be stored and then data is relocated according to the selected relocation measure.

Data storage device and storage method in which algorithms are provided

An information memory apparatus for reading/writing information from/in a plurality of detachable information storage media such as optical disks includes a storage section for calculating and storing the access frequencies of data stored in the plurality of media loaded in the apparatus, an identifying section for identifying rarely accessed data of the data stored in the access frequency storage section, and centralized relocation section for performing centralized relocation of the rarely accessed data in a specific medium of the plurality of media. The limit of the storage capacity of a system based on a fixed disk (undetachable disk) unit is theoretically eliminated.

An image processing apparatus includes a first pixel replacing unit for replacing the positions of pixels in image data in accordance with a replacement rule so as to increase redundancy of the image data, an encoder for encoding the image data supplied from the first pixel replacing unit, an optical disk device for storing the image data encoded by the encoder, a decoder for decoding the image data supplied from the optical disk device, a second pixel replacing unit for replacing the positions of pixels in the image data supplied from the decoder to restore the image data before replacement by the first pixel replacing unit, an output unit for outputting the image data, a third pixel replacing unit for replacing the positions of pixels in the image data to be outputted on the output unit, and a pixel density varying unit for varying the pixel density of the image data supplied from the third pixel replacing unit.

Image processing apparatus using high redundancy pixel replacement for

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.

Color image information processing apparatus capable of high-speed

An information processing apparatus having a scanner and a magnetic disk, both for supplying data to be stored, and an optical disk for storing the supplied data. The scanner supplies image data. The magnetic disk supplies code data such as document data and drawing data. The processing apparatus stores the image data and the code data into the optical disk, each type of data having a flag indicating its type.

Information processing apparatus

An information processing apparatus is provided with an optical disk for storing image data and code data. The code data stored in the optical disk have different data format. The optical disk further stores a flag indicating the data format of each code data. When retrieving the code data from optical disk, the processing apparatus processes the retrieved code data according to the data format indicated by the flag, and stores the processed data into a floppy disk.

Apparatus for processing code data associated with management data

A image processing apparatus includes a dither processor, which converts an electrical signal representing a continuous-tone input image into a binary image singal by a dither method using a dither matrix. The binary image signal is stored in a memory, and supplied to a pixel-density conversion processor, which converts a pixel density of the binary image signal at a predetermined ratio, and generates a converted image with the pixel coordinates as defined by the conversion ratio. A pixel coordinate calculator calculates a coordinate position of each pixel of the converted image in the binary image, and selects a fiducial pixel. A reference pixel selector defines a window area on the binary image containing the fiducial pixel and corresponding in size to the dither matrix size, and extracts reference picture elements in the window area. A calculator calculates an average image-density of the reference picture elements and generates density data, which is binarized by a second dither processor by using a second dither matrix.

Method of and apparatus for changing the pixel density of a binary image

In an image editing apparatus adapted to cut a plurality of regions of any size from a plurality of documents and prepare a new document by sticking the cut regions on a sheet. The cut regions are designated by a light pen of an instruction input section for each document displayed on a CRT display. The coordinate information of the cut regions is stored in a RAM in a sticking region computer and the image information is stored in a first buffer (RAM). A ROM in the sticking region computer stores information relating to a plurality of basic patterns representing the manner of sticking a plurality of cut regions. The coordinates of a plurality of sticking regions are calculated for each basic pattern on the basis of the coordinate data of the cut regions. An image processor causes the image data of the cut regions which are stored in the first buffer to be transferred to memory area of a second buffer (RAM) which is designated by the coordinates of the corresponding sticking regions. The editing of images is carried out for each basic pattern. The 'edited' image data stored in the second buffer is displayed on a second CRT display.
