摘要:
An information processing apparatus, including a storage device a security list, wherein a security level of each of communication protocols installed in a network is listed, a status management list, which describes validity of each communication protocol, and a protocol setting system, which sets validity of each communication protocol, is provided. The protocol setting system includes a status detecting unit, which refers to the status management list and detects validity of each communication protocol, an unsecured protocol detecting unit, which refers to the security list when at least one of the communication protocols is validated and detects a communication protocol with a security level being lower than the validated communication protocol, and a status updating unit, which invalidates the communication protocol detected by the unsecured protocol detecting unit to have the lower security level and detected to be valid by the status detecting unit.

The standard brightness region is displayed with input values of zero. The comparison brightness region is displayed with an input value which is variable in the range of 0 to 255. The standard brightness and comparison brightness regions are displayed next to each other in the display. The input value is changed from zero. A first black point is determined as an input value which causes the comparison brightness region to first appear distinguishable from the black regions of the standard brightness regions. Then, the input value is changed from 255. A second black point is determined as an input value which causes the comparison brightness region to first appear indistinguishable from the black regions of the standard brightness regions. Then, a black point is calculated as an average of the first and second black points.

In S100, multilevel density data C, M, Y, and K for a subject pixel are read out from the data recording medium. Then, the total ink density ND is calculated in S110. It is judged whether or not the total ink density ND is higher than the predetermined limit value L1. When the total density ND is not higher than the value L1 (no in S120), the original density data C, M, Y, and K for the subject pixel are subjected to the binarization process in S140. When the total density ND is higher than the value L1 (yes in S120), on the other hand, the value of the multilevel data for each chromatic color component is reduced through an ink density reduction process in S130. The thus obtained reduced multilevel data C3, M3, and Y3 and the black multilevel data are subjected to the binarization process in S140.

The pattern to be displayed on the display is constructed from at least three tone levels to display specific shapes such as letters and numeric characters. The pattern is designed so that the user will visually perceive different shapes when displayed at different display characteristics. The display characteristic is determined according to the user's perceived shape.

The first time a print program is activated, monitor calibration for calculating display characteristic of a display is executed (S10). Then the results of the monitor calibration operation are registered along with the present date (S20). The monitor calibration results and print information are outputted to a color printer (S30). The next and further times that the print program is activated, the number of days passed since the monitor calibration operation was last performed is calculated based on the previously registered date and on the present date (S40). Whether the calculated number of days exceeds a predetermined number of days is determined (S50). If so, then the monitor calibration operation is again performed (S60) and the calibration results and date are updated accordingly (S70).
摘要:
A printer setting device connected to a printer for recording, based on print data, characters and other images on a recording sheet, the printer setting device including a display displaying a menu image with various selectable operation modes including a power down mode to reduce power consumption of the printer; and a central control unit outputting a control command for setting the printer to the power down mode when the power down mode is selected on the menu image.

There is provided an image processing device communicatably connected to a network. The image processing device comprises a storage unit configured to store format information representing a format in which management information should be created; a condition obtaining unit configured to obtain condition information concerning conditions of the image processing device; a management information creation unit configured to create the management information, based on the condition information obtained by the condition obtaining unit, in the format represented by the format information stored in the storage unit; and a transmission unit configured to transmit the management information created by the management information creation unit to an external device.
摘要:
A composite service providing system including a plurality of network electronic devices communicatively connected with each other. The plurality of network electronic devices includes electronic devices, each of which is capable of providing at least one service. A plurality of services provided by a plurality of electronic devices are combined to constitute a composite service. The composite service providing system further includes a composite service designating system that designates a composite service to be provided, an electronic device determining system that determines an electronic device that provides each of a plurality of services necessary for providing the composite service designated with the composite service designating system, and a controlling system that control the electronic devices determined by the electronic device determining system to provide the services so that the composite service designated by the designating system is provided.
摘要:
An imaging system is provided with an authentication data storage that stores a plurality of pieces of authentication data in relationship to user IDs respectively representing owners of the plurality of communication devices. Further included is a reading system that reads out one of the plurality of pieces of the authentication data corresponding to a user ID if the user ID is transmitted from the external device in relationship to the image data, and a searching system searches for a communication device with which a connection authentication is established using the authentication data read out by the reading system within a predetermined communication area with respect to the imaging system. An imaging system forms an image represented by the image data transmitted in relationship to the user ID from the external device when the communication device is detected by the searching system.
摘要:
A wireless communication management system for managing a wireless communication device implemented with a security function may be provided with a security judging unit configured to judge whether a predetermined condition regarding security is satisfied, and a communication restriction unit that restricts the wireless communication with the external device if the security judging unit judges that the predetermined condition is not satisfied.
