    Abstract: Streaming magnetic tape system used as an electronic recirculating feeder for copiers and printers. Scanned and digitized original pages are stored on tape by high speed thin film parallel heads. The tape is reversed and the heads are shifted after one-half of the pages are stored on the tape. Storage of the second half of the pages results in the tape being back at the place of beginning, thus eliminating time-consuming rewinds. In one embodiment, the pages are counted before recording to ascertain the middle tape reversal location.

    Abstract: A system for self-aligning a raster input scanner in the slow scan direction where, at start of scan, a target having a variable density image is scanned first until a preset target image line is obtained and the position of the scan carriage registered; then from the registered position, the platen is scanned through a predetermined number of scan lines; following this, the carriage is reversed and returned the same number of scan lines where the target is again scanned and the target image line obtained compared with the previous target image line to determined if a valid scan cycle has taken place.

    Abstract: The surface of an original is scanned in the direction of lines with a laser beam to obtain read-out data from the reflected light beam from the original, and the read-out data for a line are first stored in a line buffer memory. Then, during the scanning for the next line by the laser beam the data which have been stored in the line buffer memory are read out and used to modulate a laser beam, with the laser beam thus modulated being led to a light-sensitive drum for making duplication of information of the read-out data.

    Abstract: An information processing apparatus for transmitting image data input by sequentially reading documents, with limiting an allowable frame size, includes: a transmission controller, wherein, in a case where the document has an irregular size, the transmission controller transmits the image data to a transmission destination in a preset frame of a first frame size until a rear edge of the document is detected, and if a portion, which is not transmitted, of the image data exists when the rear edge of the document is detected, transmits the portion to the transmission destination in a frame of a second frame size smaller than the first frame size so that the transmitting of the portion is finished before a start of transmission of image data corresponding to a next document.

    Abstract: A control device and a method for controlling scanning speed of a scanner. The control device includes a decision device and a driving device. The decision device further includes an image buffer, an up-down counter and a comparator. The decision device receives the input image data and utilizes the up-down counter to compute data access volume inside the image buffer. The comparator decides whether to increase or decrease the scanning speed according to the data access volume and also outputs decision data to the driving device.

    Abstract: Methods and systems for processing image data in connection with peripheral units such as laser printers are described. In one embodiment, an image pipeline is queried to determine at least one constraint which affects the image data provided to the image pipeline from a source of image data. If appropriate, the constraint(s) is imposed on the image data to provide constrained image data. After the constraint is imposed on the image data, the constrained image data is provided from the source to the image pipeline for processing into a page-arranged output. In another embodiment, image data which is provided by a source is stored in a first buffer. A handle is assigned to the image data. The handle is passed through at least a portion of the image pipeline. After such passing, at least a portion of the image data which was stored in the first buffer is copied directly into at least one strip buffer, with such copying being the first copying of the image data after the storing thereof in the first buffer. Other embodiments are described.

    Abstract: An image processing apparatus includes an image capture apparatus with a reduced size for capturing still image data. An extracting circuit extracts at least an area of still image data. A dividing circuit divides the area extracted by the extracting circuit into a plurality of first through nth areas. A memory circuit has a storage capacity smaller than a storage capacity required to store the still image data, and stores at least a portion of the image data of the first through nth areas provided by the dividing circuit. A transfer circuit transfers the image data stored in the memory circuit to an external device.
