Patent number: 6972796Abstract: A control device determines whether an image generated by merging several concurrently picked-up images has consistent image quality on a display device. If determined No, image quality parameters set in each image pickup device are so controlled as to make the image quality of the merged image consistent. Therefore, the merged image can assuredly have consistent image quality. Further, a signal processing device detects, based on positions of nodes and attributes of cameras, a connection indicating which node is connected to which camera and with what attribute. The signal processing device in advance stores every detectable connection and a plurality of image processing programs corresponding to each connection, and selects and carries out one of the image processing programs corresponding to the detected connection.Type: GrantFiled: February 27, 2001Date of Patent: December 6, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Noboru Katta, Hirotsugu Kawata, Susumu Ibaraki, Takahisa Sakai, Toshiaki Mori, Akihiro Yamamoto, Toshihiko Kurosaki, Yuji Mizuguchi

Publication number: 20040210932Abstract: A program preselecting apparatus is provided. An electronic program guide storing unit stores an electronic program guide made up of a plurality of sets of program information of a plurality of programs, each of the plurality of sets of program information including a time slot, channel number, and content information of a respective program. A preselection criteria storing unit stores a plurality of preselection criteria used for specifying programs to be preselected, each of the plurality of preselection criteria including at least one criterion item which specifies at least the content information. A searching unit searches, according to each of the plurality of preselection criteria, the electronic program guide for a program corresponding to each set of program information that satisfies the criterion items of the preselection criterion. An overlap judging unit judges whether there are programs whose time slots overlap among programs found as a result of the search by the searching unit.Type: ApplicationFiled: April 20, 2004Publication date: October 21, 2004Inventors: Toshiaki Mori, Noboru Katta, Hirotsugu Kawata, Toshihiko Kurosaki, Yoshiaki Kushiki

Publication number: 20010019363Abstract: A control device 3 determines whether an image generated by merging concurrently picked-up several images has consistent image quality on a display device 2. If determined No, image quality parameters set in each image pickup device 1 are so controlled as to make the image quality of the merged image consistent. Therefore, the merged image can assuredly have consistent image quality.Type: ApplicationFiled: February 27, 2001Publication date: September 6, 2001Inventors: Noboru Katta, Hirotsugu Kawata, Susumu Ibaraki, Takahisa Sakai, Toshiaki Mori, Akihiro Yamamoto, Toshiko Kurosaki, Yuji Mizuguchi
