A temperature estimation apparatus includes: a first temperature sensor that measures first temperature of first part of a target that has a heat source; a second temperature sensor that measures second temperature of second part that is farther from the heat source than the first part; and a processor. The processor obtains temperature-for-estimation data regarding the first and second temperatures that are measured in a state where a predetermined condition is satisfied, the predetermined condition corresponding to a certain state of change in the temperature of the heat source. Based on the obtained temperature-for-estimation data, the processor obtains a single thermal resistance parameter in a thermal model. Based on the obtained thermal resistance parameter and the measured first and second temperatures, the processor estimates the temperature of the heat source as a deep-body temperature of the target.

A bioinformation acquiring apparatus includes at least one processor and a memory configured to store a program to be executed in the processor. The processor acquires a waveform signal representing vibrations of a target, the vibrations resulting from heartbeats of the target; extracts provisional heartbeat timings from the acquired waveform signal based on a first time window; the provisional heartbeat timings indicating provisional values of heartbeat timings being timings at which the heartbeats of the target occur; acquires corrective peak timings from the acquired waveform signal based on a second time window having a shorter time length than the first time window, each of the corrective peak timings serving as a discrete correction unit for correction of the provisional heartbeat timings; corrects the extracted provisional heartbeat timings into definitive heartbeat timings based on the acquired corrective peak timings; and acquires bioinformation on the heartbeats of the target based on the corrected heartbeat timings.

The present invention is to reduce the time required to detect an object after completion of the rotation of a head or a body of a robot. A robotincludes a camera, and a control unitwhich determines an overlapping area between a first image captured with the cameraat first timing and a second image captured with the cameraat second timing later than the first timing to detect an object included in an area of the second image other than the determined overlapping area.

A voice input unit has predetermined directivity for acquiring a voice. A sound source arrival direction estimation unit operating as a first direction detection unit detects a first direction, which is an arrival direction of a signal voice of a predetermined target, from the acquired voice. Moreover, a sound source arrival direction estimation unit operating as a second direction detection unit detects a second direction, which is an arrival direction of a noise voice, from the acquired voice. A sound source separation unit, a sound volume calculation unit, and a detection unit having an S/N ratio calculation unit detect a sound source separation direction or a sound source separation position, based on the first direction and the second direction.

A feature extractor extracts feature quantities from a digitized speech signal and outputs the feature quantities to a likelihood calculator. A distance determiner determines the distance between a user providing speech and a speech input unit. The likelihood calculator selects registered expressions for speech recognition from a recognition target table based on the determined distance, to be used in calculation of likelihoods at the likelihood calculator. The likelihood calculator calculates likelihoods for the selected registered expressions based on the feature quantities extracted by the feature extractor, and outputs one of the registered expressions having the maximum likelihood as a result of speech recognition.

A robot determines whether a voice is a voice emanated directly from an actual person or is a voice output from a speaker of an electronic device. A controller of a robot detects a voice by means of microphones, determines whether or not a voice generating source of the detected voice is a specific voice generating source, and controls, based on a result of the determination, the robot by means of a neck joint and a chassis.

A mobile apparatus according to the present embodiment includes a voice input unit configured to detect a signal from a user. In a case where the voice input unit detects a signal from the user and as a detection result of the signal from the user, it is determined that there is a signal from the user, the mobile apparatus performs sound source localization and specifies a location or direction in which the detected signal from the user is given. In a case where it is determined that the mobile apparatus is not able to move to the location where the signal from the user is given, a voice output unit configured to output a voice signal, a driving unit configured to move the mobile apparatus, and a light emitting unit configured to emit light performs predetermined control.

A speech determiner determines whether or not a target individual is speaking when facial images of the target individual are captured. An emotion estimator estimates the emotion of the target individual using the facial images of the target individual, on the basis of the determination results of the speech determiner.

An imaging apparatus generates a 3D model using a photographed image of a subject and generates a 3D image based on the 3D model. When a corresponding point corresponding to a point forming the 3D model does not form a 3D model generated using a photographed image photographed at a different photographing position, the imaging apparatus determines that the point is noise, and removes the point determined as noise from the 3D model. The imaging apparatus generates a 3D image based on the 3D model from which the point determined as noise is removed.

The matching processor acquires the key information such as position information and/or the like by the key information acquirer, and notifies to an external apparatus via the communicator. The matching processor stores the acquired key information in the storer corresponding to the identification information which is acquired from the external apparatus. When the acquired identification information does not exist in a AR data management table, the matching processor acquires the AR data by notifying the identification information to the external apparatus. When there is no empty record in a key information management table, key information of which usage date and time is old is considered as a deletion target. Moreover, when there is no empty record in the AR data management table, the AR data of which usage date and time is old is considered as the deletion target.

The utility of a service using AR is improved. The information display apparatus which applies an information display according to augmented reality (AR) acquires a reference image for matching with a subject in a captured image and scale information which shows a scale of the subject in the reference image from an information provision apparatus. Then, an inputter-outputter of the information display apparatus displays the captured image as well as a distribution of the reference images by a scale of the subject. On this distribution display, a guide display according to the scale of the subject in the captured image is performed. This guide display moves on the distribution display corresponding to a change of an angle of view. Accordingly, it is easily set the angle of view by which the matching using the acquired reference image can be performed appropriately, and the convenience improves.
