Publication number: 20220321243Abstract: If reception quality of a broadcast signal of a first frequency received by a tuner satisfies setting conditions, the frequency received by the tuner is changed from the first frequency to a second frequency. It is evaluated whether or not the amount of offset between a reference frequency and the frequency of the signal, which is generated by converting the broadcast signal of the second frequency received by the tuner into an intermediate frequency is within a predetermined range. If the offset between the reference frequency and the frequency of the intermediate frequency signal is within the predetermined range, the data included in the broadcast signal of the first frequency is acquired by a demodulating the broadcast signal of the first frequency. It is evaluated whether or not the broadcast signal of the first frequency is a broadcast signal of a broadcasting station based on the acquired data.Type: ApplicationFiled: March 30, 2022Publication date: October 6, 2022Applicant: Faurecia Clarion Electronics Co., Ltd.Inventors: Hideki OOSHIMA, Hiroshi MATSUDA, Takeshi KUNII, Akihiko TAKADA, Yuujirou MATSUKURA

Patent number: 7953302Abstract: Information indicating an area of an image and information indicating attributes of the image have been stored in an IC chip attached to an original paper. When a copying apparatus performs a character recognition process operation with respect to an image displayed on the original paper, the copying apparatus reads the information related to the area of the image and the information related to the attribute of this area from the IC chip attached to this original paper. Then the copying apparatus separates an area where a character is displayed therefrom. The copying apparatus executes the character recognition process operation with respect to the image of the separated area.Type: GrantFiled: January 29, 2008Date of Patent: May 31, 2011Assignee: Fuji Xerox Co., Ltd.Inventors: Ryoji Watanabe, Akihiko Takada, Masayoshi Sakakibara, Hajime Kishimoto, Yasuo Horino, Toshiyuki Yano, Yasuhiro Matsuo
