摘要： Characteristic amounts in each small region of audio signals transmitted in the working system and the standby system are extracted by characteristic amount calculators 6-1, 6-2. A characteristic amount comparator 7 compares the characteristic amounts and judges occurrence of a fault. Characteristic amount difference calculators 9-1, 9-2, ∥D∥ comparator 10, and faulty system judging unit 11 judges the system having a fault. Majority decision processor 12 and significance judging unit 13 enhance the reliability of the judgment. Delay difference of audio signals between systems is roughly detected by sub-sampling audio signals of two systems and comparing them, and then accurately detected without sub-sampling. Delay difference between audio signals is adjusted by the detected delay difference.

摘要： The present invention provides a method of generating a virtual viewpoint video image when the virtual viewpoint position is not located on a plane where a camera is disposed. In an environment in which a plurality of cameras having a horizontal optical axis are disposed in a real zone (for example, on the circumference) which surrounds an object, a video image of an arbitrary viewpoint on the circumference is generated. Further, by synthesizing video images photographed by a camera, a free viewpoint video image is generated from a virtual viewpoint (viewpoint from a high or low position) where no camera is placed. According to a method of achieving this, a travel distance of a display position is calculated by the local region synthesizing portion and this travel distance is reflected to the free viewpoint video image of a local region.

摘要： The sound acquisition apparatus broadcasts a sound “output notice request” through a communication network. In response to the request by the sound acquisition apparatus, the sound output apparatus gives notification of starting a sound output operation, the sound acquisition apparatus requests the sound output apparatus to transfer “output sound data”. The sound output apparatus then transfers “output sound data” representing the sound outputted by its own speaker to the sound acquisition apparatus in response to this request. The sound acquisition apparatus then suppresses a noise component from sound data acquired through a microphone using the transferred “output sound data”.

摘要： In a wireless communication terminal, information from a wireless communication unit is decoded by a communication control unit and analysis information is acquired. A content reception judgment unit instructs the communication control unit to terminate a content receiving process if a mobile radio environment corresponding to transmission rate information of the contents, included in the analysis information, is below a content reception threshold stored in a content reception threshold storage unit. Thus, the wireless communication terminal can judge that the possibility of a failed reception is high before content reception, and needless power consumption can be prevented and power consumption reduced by not performing reception.

摘要： A device for detecting leakage of liquid in a tank, in which, even if the liquid in the tank is a low viscosity liquid, degradation in flow rate measurement accuracy by an indirectly heated flow rate meter can be suppressed, so that a very fine amount of leakage can be accurately detected for a long period without degradation in detection accuracy. The liquid in the tank that is led in and out from a liquid lead-in/lead-out section (12) is lead in and out from the lower end of a measurement fine tube (13b, 13b′, 13″) positioned in the flow rate measurement section (13). A measurement tube (17) of a liquid storage section (14) is connected to the upper end of the measurement fine tube. The measurement tube (17) has a larger cross-sectional area than the measurement fine tube. The device has a flow rate sensor section that is attached to the measurement fine tube and measures the flow rate of the liquid. The flow rate sensor section includes a heater (135) and temperature sensors (133, 134). The distance L1 in the measurement fine tube measured from a position corresponding to the heater (135) to an upper end opening of the measurement fine tube is not less than 20 mm and not more than 45 mm.
