Abstract: Transmission of an entered image, in the color mode, without passing memory means, and, in the monochromatic mode, after storage once in the memory means allows to avoid unnecessarily long image entering operation for image reading in case of monochromatic images, and also to provide an image transmitting apparatus of a smaller size and a lower cost in comparison with the conventional color communication apparatus. Also processing of a received color image without passing memory means and of a received monochromatic image through the memory means allows to store such monochromatic image even in the absence of a recording material and to provide an image receiving apparatus of a smaller size and a lower cost in comparison with the conventional color communication apparatus.

Abstract: An image of an original mounted on a platen is converted into image data by a CCD. An original region detection unit detects the region of the original mounted on the platen from the image data. According to this detection, the writing address of the image memory is controlled so that image data of the center of the original mounted region is written into an address matching the center of the sheet. As a result, various image editorial processes can easily be carried out in a digital copy machine.

A first character/line drawing data is separated from an input multivalue image data to be subjected to an image data processing for removing jaggies appearing in curved or straight lines of characters and lines, and then is synthesized with a patter data having data indicative of edge directions to generate an output multivalue image data, so as to provide the hard copy having high visual quality.

Abstract: An apparatus for selecting and controlling devices located remotely from a local site where an operator resides. A laser or other source of a focused electromagnetic bean moves in association with a camera located at the remote site. The camera thus can detect the object on which the focused laser beam projects. The camera outputs a video signal which is transmitted from the remote site to the local site. The operator at the local site views the video signal on a monitor so that the operator can determine the location of the laser beam. When the laser beam illuminates at least one particular transponder out of one or a plurality of transponders, the transponder outputs a signal to at least one device to activate or deactivate the device, thus providing the operator remote control of the device. A light may also be associated with the transponder and activates when the transponder has been selected to provide a positive indication to the operator that only the particular transponder has been selected.

Abstract: An improved networked system having a host computer and multiple printers is provided in which the printers have a bi-directional data communications capability and have at least one memory device capable of storing print data and other types of data files. The host computer can be utilized by a user or a Network Administrator to "read" the contents of each memory device on each printer connected to the network that has the NPAP bi-directional communications capability. The user/Network Administrator can transfer a file from the memory of one of the printers on the network to the memory of a second of the printers on the network. When a given resource management function has been completed, an updated resource directory is automatically displayed at the host which includes all of the changes resulting from the earlier resource management function command.

Abstract: In a printing apparatus, recording paper is fed from a paper roll to a platen roller, and is printed by a print head by an amount corresponding to one page, and then the printed recording paper is cut by a cutter. A curl removal member for removing a curl from the recording paper is shifted into an operative or curl-removing-position, and flexes or curves the recording paper from the paper roll, thereby removing a curl thereof. For finishing the printing operation after cutting the recording paper, the curl removal member is shifted into an inoperative position where it does not flex the recording paper, and the platen roller is rotated in a normal direction to remove a slack from that portion of the recording paper extending between the paper roll and the print head. For starting the printing operation, the platen roller is rotated in a reverse direction, and the curl removal member is shifted into the operative position to flex the recording paper, and then the printing of the recording paper is started.

The triggering event can be one of a predetermined set of system operating conditions.

Abstract: An arrangement for illuminating objects wherein a large number of objects are rapidly and continuously transported past one or more stations, each illuminated by a cylindrical, integrating Lambertian reflecting/diffusing cavity having one or more like light sources therein so as to generate and project a highly intense, highly uniform and highly diffuse beam of illumination, while incorporating optical guide means to couple said illumination beam to the face of the objects at said station and to couple the reflected image of the object back to the cavity.

Abstract: Printing in which printer resources that are consumed in forming a raster image are predicted and in which those printer resources are re-allocated in a case where printer resources are predicted to be exceeded. Specifically, coded print data such as coded print data in a page description language is input, the coded print data is translated into a first coded representation, and the first coded representation is translated into a second coded representation which is different from the first coded representation. Printer resources consumed in forming a raster image corresponding to the coded print data in the second coded representation are predicted, and printer resources are re-allocated in a case where printer resources are predicted to be exceeded. A raster image is thereafter formed from the second coded representation.

Abstract: A color image processing system in which image data generated in other systems can be commonly used is disclosed. In the color image data processing system, an image processing unit processes color image data represented in a uniform color space system under illumination by a first light source, and the image data includes information relating to the first light source. An image output unit receives color image data represented in a uniform color space system under illumination by a second light source and produces color images according to the color image data. A correction control unit in the image processing unit judges whether or not the first light source coincides with the second light source. A correction formula calculating unit calculates a correction formula corresponding to the difference in characteristics between the first light source and the second light source. A light source difference correction unit corrects the color image data according to the correction formula.
