Abstract: Provided is a state recognizing device including: a first filter unit performing a filtering process on a time-series signal obtained by performing remote measuring on a space, in accordance with a first cutoff frequency to allow a signal component deriving from movement of a biological organism to pass through; a second filter unit performing a filtering process on the time-series signal in accordance with a second cutoff frequency to allow a signal component based on biological information to pass through; an amplitude-component extracting unit extracting a first feature quantity related to an amplitude component from a signal passed through the first and/or second filter units; a frequency-component extracting unit extracting a second feature quantity related to a frequency component from a signal passed through the first and/or second filter units; and a recognizing unit recognizing a state of the space by using the first and second feature quantities.

Abstract: To improve the accuracy of the determination on whether or not a moving object is present in a predetermined region, a control device for use in a system configured to conduct presence-or-absence determination on whether or not a moving object is present on the basis of detection by a first sensor provided in a predetermined compartment region, the control device comprising: a mode control section configured to control switching of an operation mode for the detection by the first sensor or the presence-or-absence determination; and an acquisition section configured to acquire a determination result of whether or not a moving object is present in an adjacent region adjacent to the predetermined compartment region and not including the predetermined compartment region; wherein the mode control section controls the switching of the operation mode in response to the determination result acquired by the acquisition section, is provided.

Abstract: [Object] To provide a characteristic-value calculating device, a characteristic-value calculating method, and a recording medium that can extract a characteristic value for more accurately recognizing the state of a moving object, such as a human, from a Doppler signal. [Solution] A characteristic-value calculating device includes an acquiring unit that acquires a Doppler signal, an extracting unit that extracts a time-series signal constituted of a predetermined frequency component from the Doppler signal acquired by the acquiring unit, a selecting unit that selects a signal value at a predetermined interval from the time-series signal extracted by the extracting unit, and a calculating unit that calculates higher-order local autocorrelation based on the signal value selected by the selecting unit.

Abstract: In an image composer includes a storage for storing a first and a second image, a region classifier compares the first image with the second image to extract as a non-common sub-region a partial region of one of the two images that does not have a similar pixel property to that of the other image. An image composing unit superimposes the extracted non-common sub-region of one of the images onto the other image to produce a resultant composite image.
