Abstract: An image forming apparatus includes a condition determining device that calculates a deviation amount of image data from a normal condition and determines if the image forming apparatus is in an abnormal condition. An abnormal section specifying device specifies an abnormal section in the image forming apparatus based on a condition of the image forming apparatus. An image processing device executes image processing for abnormal use in accordance with an output of the abnormal section specifying device when the image data condition determining device determines that the image forming apparatus is in an abnormal condition. A service person call output device outputs a service person call signal indicative of calling a service person to a center when the image data condition determining device determines that the image forming apparatus is in an abnormal condition.

Abstract: An image processing apparatus includes: an extractor to extract colors used in input data; a converter to convert signals of the extracted colors into intermediate color signals each including three color signal components including brightness; an evaluator to evaluate recognizabilities of the colors based on the intermediate color signals; a generator to generate additional image data to be added to data for ordinary image formation based on a result of the evaluation and the input data; and a color convertor to convert the input data into the data for ordinary image formation.

Abstract: An image processing apparatus includes a color converting unit that converts input image data into image forming data used for image formation; and a control unit that controls the image formation by the image forming data, wherein the color converting unit converts each of a plurality of predetermined colors that are difficult for colorblind people to mutually distinguish among colors included in a color space of the input image data, as difficult colors for colorblind people, into a same color in a color space of the image forming data.

Abstract: An apparatus, method, system, computer program and product, capable of detecting a current state of an image processing apparatus and selecting image processing based on the detected current state are disclosed. The detected current state may be used to determine whether to generate a service call signal.

Abstract: An image processing apparatus that stores input image data is disclosed. The image processing apparatus includes a color space evaluating unit which evaluates a color space of the input image data by comparing the color space of the input image data with a reference color space, a frequency distribution calculating unit which calculates an appearing frequency distribution of a color included in the input image data, and a color space determining unit which determines a color space in which the input image data are to be stored by applying color control to the input image data based on the evaluated result by the color space evaluating unit and the calculated result by the frequency distribution calculating unit.

Abstract: A converting unit converts a first color signal into a second color signal and a third color signal. A first correcting unit corrects a magnitude relation between hue angles of the third color signal such that a magnitude relation between hue angles of the second color signal corresponding to the first color signal is maintained in the hue angles of the third color signal. The first color signal is a device-dependent input red, green, blue color signal. The second color signal is a color signal of a hue, lightness, saturation color space. The third color signal is a color signal of CIECAM02 color space.

Abstract: A packet buffer management method and system are provided which enable maximum utilization of the hardware resources of the buffer memory, and which are optimum for the number of preset physical ports in use or for the number of service class (CoS) areas. In the buffer memory management method in a packet transmission/reception device, for storing a received packet in the buffer memory and controlling writing and reading of packets to and from the above buffer memory, the control methods are set in units of the service class contained in the header portion of received packets, and areas allocated to each service class in the buffer memory storing received packets are modified according to the set number of the above service classes.

Abstract: After an event processing that an application program corresponding to a first event request information should execute is executed with respect to at least one of window objects and variables which should be contained in the application program applicable to a first event request from a client PC, a Web server maintains the window object and variable, which are after the event processing, into a Web session and, at the same time, transmits the window object after the event processing to the client PC. Further, when the Web server further receives a second event request applicable to the same application program, the Web server executes an event processing corresponding to the second event request using the window object and variable stored in the Web session.

Abstract: Data arriving from a plurality of channels asynchronously to each other are respectively stored in separate FIFOs (10). A controller (12) monitors the status of the FIFOs (10), retrieves the stored data in a predetermined order, and multiplexes the data, together with timing data indicating the presence or absence of the data, into a serial signal having a frame structure in which time slots are fixedly assigned to the respective channels. On the serial data, the same value appears successively as data, and when the data is valid, the corresponding timing data changes from a 0 to a 1. When the data is invalid, the value of the corresponding timing data does not change.
