摘要:
An image reading apparatus according to the present invention comprises a first unit for scanning an original while exposing the original to light, and a second unit detachably provided to the first unit for receiving light from the first unit and converting an original image into electrical signals. The first unit includes a light source for irradiating the original and an optical member for projecting the original image at a predetermined position. The second unit is provided in the vicinity of the predetermined position and includes an image sensor for reading the original image to generate the electrical signals, a signal processing portion for processing the electrical signals generated from the image sensor, and a storage portion for storing the processed electrical signals.

In a facsimile apparatus including a continuous transmission function, an image reader reads images of first and second documents to be transmitted set thereon and converts the read images into first and second image data, respectively, and a reservation controller controls a transmitter to start transmitting the second image data at a predetermined timing. Further, there is provided a judgment controller for judging whether or not the first and second receiver parties agree with each other when the first image data are transmitted by the transmitter after a communication line controller connects the transmitter through a communication line with a facsimile apparatus of the first receiver party, and a transmission controller for controlling the transmitter and the communication line controller to start transmitting the second image data without disconnecting the transmitter from the facsimile apparatus of the first receiver party after completion of transmitting the first image data, when the agreement of the receiver parties is judged by the judgment controller.

An image reader for reading an image of a document by an image sensor and for outputting image data after processing obtained image data includes an arrangement for binarizing image data read by the image sensor through comparison of the image data with a threshold. A system is provided for entering the threshold value from an exterior source and for giving the threshold value to the binarizing arrangement. Also, a control device is provided for controlling that system.

A plurality of index members are arranged at desired positions on an end portion of a platen glass, the members being movable in a scanning direction of a scanner. A black mark is provided on a rear surface of each index member, and the mark as well as the original are read by an image reader, so that the positions of the index members can be detected. When one of the index members is detected as the scanner is moved, the image signals of the original included in the scanning region of the scanner are not outputted until the next index member is detected. In this manner, by continuously outputting image signals only of the desired areas of the original, the column skip edition can be readily and surely carried out.
摘要:
There is disclosed a method for processing image data wherein each picture element represented by a two dimensional density pattern in a form of matrix of M rows and N columns is transformed to a one dimensional density pattern and image data represented by one dimensional density patterns are compressed by a conventional data compression method.

An image reader having a scanning optical means for a document, a projection lens and an image sensor for reading an image of a document is disclosed. The image reader includes a pattern element on which a predetermined pattern having two edges symmetric with respect to the optical axis of the projection lens at a predetermined reading magnification and a circuit for determining the center position of an image of a document based on data obtained when the predetermined pattern is read by the image sensor through the projection lens at a designated reading magnification.
摘要:
An image reader comprises a line image sensor for reading images of an original for every line, a CPU for extracting the density level of the background based on the read image data for comparing the extracted density level with a reference level to find the difference, light adjusting circuit for adjusting the intensity of a lamp for exposing the original so as to make the difference obtained by the operation equal to 0 and a compare circuit for converting the read image data to binary data, wherein the adjustment of the intensity of the lamp by the light adjusting circuit is carried out in parallel to the conversion of the image data by the compare circuit.
摘要:
An image reader comprising a variable magnification system for moving a lens disposed between an image of a document and an image sensor is disclosed. The focus adjustment is performed by moving the image sensor in a direction parallel to an optical axis of the lens. An initializing processing is finished without the focus adjustment in case the image formed on the image sensor is in the infocus condition when the power is supplied to the image reader and the magnification is the equal last magnification.

An administrator instructs creation of a volume to a virtual storage device and registration of a host port for providing access permission to the volume. The virtual storage device searches a candidate of a physical storage device capable of reaching the host port and a candidate of the target port based on the access permission information, and creates a distributed volume astride the candidate physical storage device. The distributed volume is composed of a plurality of partial volumes, and the partial volumes inherit the functions of the storage device and the access permission information set for the distributed volume. The virtual storage device distributes an access permission to the physical storage device, constitutes the access permission information of the host port and the volume with respect to the candidate target port, and registers the access permission information of the host port and the target port to the SAN switch.
摘要:
A virtual LU astride a plurality of storage devices is a virtual volume composed of a plurality of partial volumes. Functions of the storage system, Zoning information of a SAN and a host group information of the virtual volume are inherited to a partial volume created for each physical device. When a page granularity data migration is executed, volume or data are migrated to other storage devices without depending on the relationship between a physical port and the physical device. When a host IO request is received when migration is on-going, response processing is performed by synchronizing storage devices within the range of migration data. The host IO request related to the page being migrated sends a partial complete response including information for re-routing the request to a path of the appropriate data migration destination device capable of issuing the IO.
