In a network connecting a plurality of devices, the image processing function of each device, information for specifying each device, and the like are collected and controlled, and functions realizable by combining two or more devices are determined. Profiles indicating respective combinations are transferred to each device. Each device which has received the profiles displays executable functions based on the profiles, and performs control, such as the operation of the device, transfer of data, and the like, in order to realize a function selected from among the displayed functions.

Data processing apparatus connected to a network connectable a plurality of devices

Each of input and output devices previously forms device profile, and a host computer acquires virtual input/output device information including a pair of ideal input and output devices on the basis of the device profiles of these devices. If the virtual input/output device information is acquired, the input device demands to acquire a transfer path profile included in the virtual input/output device information, and then demands if the transfer path profile is acquired the output device registered in the acquired transfer path profile to connect a line. If the line connection is established, the input device performs data inputting such that the acquired transfer path profile is reflected in the device setting, and then it transfers the input data to the desired output device.

Information processing system and information processing method

An original is allowed to pass on an exposing glass along a conveying path, thereby exposing and scanning a front surface of the original and reading an image by a CCD. A back surface of the original is subsequently fed to the exposing glass along a conveying path and is allowed to pass on the exposing glass, thereby exposing and scanning the back surface of the original. The image data read by the CCD is stored into an image buffer. The order of address columns to read out the image data on the front surface and the order of address columns to read out the image data of the back surface are made opposite. Thus, a copying apparatus which can efficiently expose and scan both of the front and back surfaces of a both-side original is provided.

Copying apparatus capable of exposing and scanning both-side original

An image processing apparatus includes a processing unit for processing an image signal into which an original document, after being exposed to light, is photoelectrically converted, a compression module for compressing image information processed through the processing unit, a memory for storing image data compressed by the compression module, a control unit for setting a diversity of image processing modes, and a predicting module for predicting an image compression rate used by the compression module. The predicting module predicts the image compression rate of an image after being processed according to the image processing mode set by the control unit.

Image processing apparatus and method for predicting a compression rate

In continuously writing image data transferred from an image plane spreading two-dimensionally in a memory plane spreading two-dimensionally, or continuously reading out image data from the memory plane, a first address for accessing image data of a predetermined unit block in the image plane is converted into a second address. The image data of the unit block is stored as one-row image data in a one-row storage area of the memory plane which is designated by the second address. Predetermined image processing of the image data corresponding to the unit block is performed by reading out the image data from the one-row storage area in the row direction in the memory plane.

Image processing apparatus and method

An original document reading apparatus includes a first control portion for performing a first control wherein documents are transported at a first document interval in the event that a detected occupying capacity is less than a detected unused capacity. The first control portion also performs a second control wherein documents are transported at a second document interval which is greater than the first document interval in the event that the detected occupying capacity exceeds the detected unused capacity. A second control portion continuously activates an exposure portion under the first control, and intermittently activates the exposure portion under the second control.

The present invention relates to an image processing apparatus and a method of forming an image by separating color information into two or more color information items. The boundary of images is compensated, the images being the images formed by an analog recording system for forming an image on a recording medium by removing a predetermined color component from an original document image and a digital recording system for forming an image on said recording medium by extracting a predetermined color component from said original document image. Therefore, if a slight positional deviation takes place between images formed by the analog recording system and the digital recording system, a want of color information can be prevented. Therefore, the deviation can be satisfactorily compensated so that an original image can be correctly reproduced.

The controller unit 2a can perform in a color extraction mode and a marker processing mode. The color extraction mode is a mode in which an image within the range of a particular color is extracted and reproduced in that color. In the marker processing mode, an area surrounded by a color marker is detected and a prescribed processing is performed for an image in that area. A main-scan smoothing circuit 130 changes the number of pixels or the weighting coefficients used in smoothing in accordance with above described modes.
