摘要： In a shadow process mode, a scanner reads out an original with a first exposure lamp in a first scanning operation. The readout image data is stored in an image memory via an I/O control unit. In the second scanning operation, the scanner reads out the original with a second exposure lamp having an illumination direction different from that of the first exposure lamp. The image data read out in the second scanning operation and the data stored in the image memory are subtracted for each pixel by a subtractor. The difference thereof is compared with a predetermined value in a comparator. The compared result is output to a selector, whereby a desired image data is provided to a printer processing unit via the I/O control unit.

摘要： An image forming apparatus includes an image reading device which extracts character images from an original document image read by an image reader. The reading device further extracts an area of predetermined size including a single character from the extracted character images, and detects punctuation marks among characters included in the respective extracted areas based on a distribution of image elements in the respective extracted area so as to discriminate the directional orientation of the character image based on a position of punctuation marks. Alternatively, the reading device detects the presence of white space in the extracted character images so as to discriminate the directional orientation of the character images based on a distribution of the detected white space.

摘要： Originals are fed onto a platen glass one by one by an automatic original feeder to be read out by a reading system. The originals are converted into digital image data. The image data is transferred to a memory unit. The memory unit is controlled by a CPU. The memory unit is configured of an image memory, a sentence direction recognizing portion, an RAM producing a management table, an original direction (top and bottom direction) recognizing portion, a rotation processing portion, a sign memory and the like. Based on top and bottom directions of original images and directions in which sentences run included in the images, arrangement of images in a 2in1 or 4in1 mode is determined.

摘要： 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： Even when there is some degree of variation in the characteristics among components constituting a polyphase motor and a driving circuit therefor, current control signals of respective phases being input to the drive circuit have their amplitude finely adjusted by an amplitude control circuit, so that amplitude is uniform among armature currents of respective phases that are ultimately output from the drive circuit. The amplitude adjusting circuit is configured by gain variable amplifiers, for example. Thus, rotation fluctuation and vibration of the polyphase motor can be reduced.

摘要： A host computer is coupled to a first fabric, a source storage apparatus is coupled to a second fabric, and a destination storage apparatus is coupled to a third fabric. A destination port of the destination storage apparatus comprises a same WWPN as a WWPN of a source port, and is logged in to the fabric beforehand. Duplicate WWPNs are allowed to exist because an inter fabric router separately manages the second fabric and the third fabric. When a switchover is instructed, the inter fabric router switches a coupling destination of the host computer to the destination storage apparatus.

摘要： In a case where a failure has occurred in one of fabric management mechanisms, nodes resume data I/O communications without degrading performance and without changing the data I/O communication path between the nodes by switching control to the other one of the fabric management mechanisms. The fabric management mechanisms share management information with each other. When a failure occurs in either of the fabric management mechanisms, an E_Node that belongs to the domain, in which a failure has occurred, logs into a normal fabric management mechanism via a newly created management-use communication path. The normal fabric management mechanism allocates an N_Port_ID on the basis of a virtual FC domain number that has been allocated to a switch.
