A projector includes a projecting unit that projects a calibration image containing a plurality of types of pattern images having different shapes, a storing unit that stores correction data showing a correction value for each of the pattern images, a selecting unit that receives selection of a pattern image selected by a user from the pattern images, and a correcting unit that corrects distortion of an image projected by the projecting unit based on the correction value corresponding to the selection.

A network device comprises a Web service provider unit. In order to provide a client in a network with a service to display a list of multiple images stored in a predetermined storage area, the client having a function as a Web browser, the Web service provider unit sends the client in response to a request from the client a markup language file described in a predetermined markup language. The Web service provider unit includes a layer configuration unit and a Web program generator. The layer configuration unit configures as an element included in the markup language file at least one layer having a visibility attribute that defines whether or not the layer will be displayed on the client and assigns each of the multiple images to one of the layer. The Web program generator generates a Web program that operates on the client and sends the Web program to the client. The Web program is a program that causes the client to implement a first function to set the visibility attribute of the layer and a second function to issue a request to obtain each of the multiple images such that each of the multiple images is respectively placed on the layer to which the image is assigned.

User-friendliness in image list display

Since an MIB file present in a network device and having the structure of MIB data is expressed in the ASN1 format, the MIB file is not flexibly modified by a user. A management-information database-structure definition file converter unitconverts MIB files. . . having the MIB data structures of MIB databases, . . . mounted on the network devices, . . . into files in a tag-structured format. Specifically, the management-information database-structure definition file converter unitconverts MIB files, . . . into MIB files. . . in a tag-structured format (XML format). Using the MIB files, . . . in the XML format, a network device management toolmanages the MIB databases. . . of the respective network devices

If the definition of one MIB tree structure is dispersed across a plurality of MIB files, a desired object ID cannot be acquired without sequentially searching a several MIB files when the object ID is searched for. A management device includes a file linking unit linking a plurality of management-information database structure definition files (MIB files). The file linking unit reads header portions of a plurality of MIB files, learns the connection relationship of the plurality of MIB files from the read content, determines the order of linking from the learned connection relationship, and links the plurality of MIB files while reorganizing the content of each of the MIB files, thereby obtaining a single file MIB (linked MIB file).
