摘要:
A relay station 200 constructs an infrastructure wireless network 200L. A printing device 100 requests new participation in the wireless network 200L. When preset conditions are satisfied, for example, when the user has pressed a push button 201 provided on the relay station 200, the relay station 200 establishes temporary wireless communication with the printing device 100 and changes an SSID of the printing device 100 to an SSID of the relay station 200. In this manner, this arrangement readily changes the configuration information of the printing device 100.

摘要:
There are provided a foreground region extraction program, a foreground region extraction apparatus, and a foreground region extraction method capable of clipping an object region (foreground region) at high speed.An arrangement is as follows: Foreground pixels designated by a user and background pixels designated thereby are each set as a reference pixel to identify, from among a plurality of divided color spaces created by a three-dimensional color space being divided, the divided color space to which each of the reference pixels belongs, as a reference divided color space. Color distance calculation processing to calculate a color distance in the color space between each reference pixel and an adjacent pixel adjacent thereto is performed, and belonging judgment processing to judge whether each of the adjacent pixels belongs to each of the reference divided color spaces is performed, and then, cost calculation processing to calculate a cost of each adjacent pixel is performed, based on the color distance calculated for each of the adjacent pixels, and weights based on whether to belong to the reference divided color space judged for each of the adjacent pixels. Further determination processing to determine the adjacent pixel having the lowest calculated cost as a foreground pixel or background pixel is performed, and a foreground region is extracted from the image by using the determined adjacent pixel as a reference pixel to repeatedly perform the color distance calculation processing, the belonging judgment processing, the cost calculation processing, and the determination processing.

摘要:
A method of making a usage request for one or more of a plurality of request-accepting apparatuses that accept one or more usage requests in a network system including a plurality of request-making apparatuses that make one or more usage requests, and the request-accepting apparatuses, including: upon a request-making apparatus from among the request-making apparatuses receiving an instruction to use one of the request-accepting apparatuses, notifying two or more of the request-accepting apparatuses of a usage request; and upon the request-making apparatus receiving, from a request-accepting apparatus from among the request-accepting apparatuses notified of the usage request, information indicating that the request-accepting apparatus is currently available, setting the request-accepting apparatus the information was received from as an object to be used, and notifying the one or more request-accepting apparatuses notified of the usage request other than the one set as the object to be used of cancellation of the usage request.
