Description

  The present technology relates to an electronic device, a control method, and a program, and more particularly, to an electronic device, a control method, and a program that can appropriately warn a person who needs a warning.

  In recent years, with the widespread use of wearable terminals, there is a concern that moving images will be taken without being noticed by the person who is the subject.

  For example, in a photographing device, the surroundings are notified by, for example, illuminating an LED during moving image photographing. However, in a wearable terminal, it is difficult to know whether or not a photographer is photographing because the photographer does not need to hold the camera.

  In response to such a problem, for example, an electronic device that generates a warning sound to warn a subject person has been proposed (see, for example, Patent Document 1). There has also been proposed an apparatus that measures the distance to the subject according to the in-focus position of the image and changes the volume of the warning sound according to the measured distance and outputs the same (for example, see Patent Document 2).

  Hereinafter, a shooting warning function of the video camera 1 will be described.

<Functional block diagram>
FIG. 2 is a block diagram relating to the shooting warning function of the video camera 1.

  The video camera 1 includes an image acquisition unit 31, a subject detection unit 32, a white list storage unit 33, a person verification unit 34, a distance direction calculation unit 35, a voice acquisition unit 36, a warning sound detection unit 37, a warning sound output control unit 38, And a recording control unit 39. Each unit shown in FIG. 2 corresponds to a function executed by the control unit 13 of FIG. 1 and the memory unit 18 used as a work area when the control unit 13 executes a predetermined control process.

  The image acquisition unit 31 acquires a plurality of captured images simultaneously captured by the stereo camera 12 and supplies them to the subject detection unit 32 and the distance direction calculation unit 35.

  The subject detection unit 32 executes a person recognition process for detecting a person appearing as a subject in the captured image supplied from the image acquisition unit 31. For example, the subject detection unit 32 detects a person in the captured image by detecting the face of the person or detecting a human figure (silhouette). Then, the detected face image (face image) of the person is supplied from the subject detection unit 32 to the person verification unit 34.

  In addition, the subject detection unit 32 detects the direction of the line of sight of the face in the photographed image, and the person in the photographed image turns the face toward the video camera 1 within a predetermined time after generating the warning sound. The face image of the person facing the video camera 1 is detected as a person noticing shooting and is stored in the white list storage unit 33.

  The white list storage unit 33 stores face images of persons registered in advance as a white list in the registration mode. The white list is a list of persons who do not need a warning sound. The face image stored in advance as a white list in the registration mode may be an image taken by the stereo camera 12 of the video camera 1, or image data of a face image taken by another imaging device may be used as a communication I / O (not shown). What was memorize | stored in the white list memory | storage part 33 via F may be used.

  The white list storage unit 33 supplies the face image of the subject in the captured image determined to be a person who is aware of the shooting from the subject detection unit 32 and stores it as a white list.

  The person collation unit 34 collates the person of the face image supplied from the subject detection unit 32 with the person registered in the white list of the white list storage unit 33. In other words, the person verification unit 34 determines whether or not the person of the face image supplied from the subject detection unit 32 is a person registered in the white list. When a person who is not registered in the white list is detected, the person verification unit 34 supplies the person specifying information for specifying the warning target person to the distance direction calculation unit 35 with the person as the warning target person. The person specifying information is, for example, the face image of the warning target person itself or position information indicating the position of the face image of the warning target person in the captured image.

  The distance direction calculation unit 35 calculates the distance and direction to the warning target person based on the photographed image supplied from the image acquisition unit 31 and the person specifying information supplied from the person verification unit 34. More specifically, the distance direction calculation unit 35 determines the distance and direction from the two images supplied from the image acquisition unit 31 at the same time by the stereo camera 12 to the warning target person based on the principle of triangulation. Is calculated. The calculated distance and direction to the warning target person are supplied to the warning sound output control unit 38.

  The sound acquisition unit 36 acquires the sound of the ambient sound collected by the sound input unit 16 and supplies it to the warning sound detection unit 37.

  The warning sound detection unit 37 detects a warning sound included in the surrounding sound supplied from the sound acquisition unit 36. Since the warning sound is a sound that is controlled by the warning sound output control unit 38 and is output from the voice output unit 17, the timing and characteristics of the warning sound are known. Specifically, it is known that, for example, a signal having a predetermined frequency in the high sound range is transmitted as a warning sound at a specific pitch (output interval) a specific number of times. The warning sound detection unit 37 compares a frequency analysis result obtained by performing a fast Fourier transform (FFT) on the warning sound signal and a frequency analysis result obtained by performing a fast Fourier transform on the sound signal of the ambient sound supplied from the sound acquisition unit 36. Thus, a warning sound included in the sound of the ambient sound supplied from the sound acquisition unit 36 is detected. Further, the warning sound detection unit 37 can also confirm the volume level of the warning sound by measuring the amplitude of the signal corresponding to the detected warning sound.

  The warning sound detection unit 37 supplies a control signal (recording stop signal) for stopping recording to the recording control unit 39 when no warning sound is detected. On the other hand, when a warning sound is detected, but the detected volume is lower than a predetermined threshold, the warning sound detection unit 37 sends a control signal (volume adjustment signal) for adjusting the volume of the warning sound to an appropriate value. The alarm sound output control unit 38 is supplied.

  When the distance and direction of the warning sound are supplied from the distance direction calculation unit 35, the warning sound output control unit 38 controls the audio output unit 17 so that the warning sound is emitted in the distance and direction. In other words, the warning sound output control unit 38 controls the sound output unit 17 so that a warning sound is emitted in the direction of the warning target person at a volume that reaches the warning target person.

  In addition, when a volume adjustment signal for adjusting the volume of the warning sound to an appropriate value is supplied from the warning sound detection section 37, the warning sound output control section 38 sets the volume of the warning sound based on the volume adjustment signal. The audio output unit 17 is controlled.

  The recording control unit 39 stops recording when a recording stop signal is supplied from the warning sound detection unit 37.

<Flowchart>
Next, warning sound output control processing by the video camera 1 will be described with reference to the flowchart of FIG. This process is started together with the execution of recording, for example.

  First, in step S <b> 1, the image acquisition unit 31 acquires a captured image captured by the stereo camera 12 and supplies it to the subject detection unit 32 and the distance direction calculation unit 35.

  In step S2, the subject detection unit 32 performs a person recognition process for detecting a person appearing as a subject in the captured image supplied from the image acquisition unit 31, and in step S3, determines whether a person is detected in the captured image. judge.

  If it is determined in step S3 that no person has been detected in the captured image, the process returns to step S1, and the subsequent processes are executed. In this case, recording is performed as it is.

  On the other hand, if it is determined in step S3 that a person has been detected in the captured image, the process proceeds to step S4, and the subject detection unit 32 supplies the detected face image of the person to the person verification unit 34. Then, the person collation unit 34 collates the person in the face image supplied from the subject detection unit 32 with the person registered in the white list in the white list storage unit 33.

  In step S <b> 5, the person collation unit 34 detects whether the person (face image) detected in the captured image matches any of the persons (face images) registered in the white list. Each determined person is determined.

  If it is determined in step S5 that all the persons detected in the captured image match the persons registered in the white list, the process returns to step S1 and the subsequent processes are executed. In this case, recording is performed as it is.

  On the other hand, if it is determined in step S5 that at least one of the persons detected in the photographed image does not match the person registered in the white list, the process proceeds to step S6, and the person verification unit 34 enters the white list. A person who is not registered is determined as a warning target person, and the person specifying information of the warning target person is supplied to the distance direction calculation unit 35.

  In step S <b> 7, the distance direction calculation unit 35 calculates the distance and direction to the warning target person based on the photographed image supplied from the image acquisition unit 31 and the person specifying information supplied from the person verification unit 34. To the warning sound output control unit 38.

  In step S <b> 8, the warning sound output control unit 38 sets the volume and direction corresponding to the distance supplied from the distance direction calculation unit 35, and controls the audio output unit 17. In step S <b> 9, the sound output unit 17 outputs a warning sound based on the direction and volume set by the warning sound output control unit 38.

  In step S <b> 10, the sound acquisition unit 36 acquires the sound of the ambient sound collected by the sound input unit 16 and supplies it to the warning sound detection unit 37.

  In step S <b> 11, the warning sound detection unit 37 detects whether a warning sound is detected in the ambient sound supplied from the sound acquisition unit 36, or more specifically, converts the warning sound into a sound signal for a predetermined period after the warning sound is output. It is determined whether an audio signal having a warning sound feature point is included.

  If it is determined in step S11 that a warning sound has been detected in the collected ambient sound, the process proceeds to step S12, and the warning sound detection unit 37 determines the volume level of the detected warning sound. To do.

  In step S11, as shown in FIG. 4, the warning sound detection unit 37 is based on the volume of the warning sound output by the audio output unit 17, and the volume level that will be detected when the sound is picked up. Assuming that the expected value is 100%, the volume level of the detected warning sound is a small level less than the first threshold VM1, or a medium level less than the first threshold VM1 and less than the second threshold VM2, or It is determined whether the level is greater than or equal to the second threshold VM2.

  If it is determined in step S12 that the volume level of the detected warning sound is high, the process returns to step S1, and the subsequent processes are executed. That is, when the volume level of the warning sound is high, it is assumed that the warning sound that informs the user that the image is being taken has reached the warning target person, so the recording is executed as it is.

  On the other hand, if it is determined in step S12 that the volume level of the detected warning sound is low, the process proceeds to step S13, and the warning sound detection unit 37 sends a recording stop signal for stopping the recording to the recording control unit. 39. The recording control unit 39 stops recording based on the recording stop signal from the warning sound detection unit 37.

  That is, when the volume level of the warning sound is low, it is assumed that the warning sound notifying that the shooting is in progress has not arrived at the warning target person, so that the recording is stopped. Since the recording is stopped, the warning sound output control process is also ended.

  On the other hand, if it is determined in step S12 that the volume level of the detected warning sound is a medium level, the process proceeds to step S14, and the warning sound detection unit 37 adjusts the volume of the warning sound to an appropriate value. The adjustment signal is supplied to the warning sound output control unit 38. After step S14, the process returns to step S9, and a warning sound is output with the readjusted volume and direction.

  In other words, when the volume level of the warning sound is medium level, it is assumed that the warning sound has not reached the warning target person because the volume is not appropriate. Is emitted.

  On the other hand, if it is determined in step S11 that no warning sound has been detected in the collected ambient sound, the process proceeds to step S15, and the warning sound detecting unit 37 detects the collected ambient sound. Determine whether the volume level is higher than the high level.

  If it is determined in step S15 that the volume level of the ambient sound is greater than or equal to the high level, the process proceeds to step S14. As a result, in step S14, a volume adjustment signal for adjusting the volume of the warning sound to an appropriate value is supplied to the warning sound output control unit 38. In step S9, the warning sound is re-adjusted with the readjusted volume and direction. Is output.

  If it is determined in step S15 that the volume level of the ambient sound is greater than or equal to the high level, the ambient sound is detected even in a situation where the warning sound is not detected. It is assumed that was not detected. Therefore, the process proceeds to step S14, the volume of the warning sound is readjusted, and the warning sound is output again.

  On the other hand, if it is determined in step S15 that the volume level of the ambient sound is less than the high level, the process proceeds to step S13. As a result, in step S13, a recording stop signal for stopping the recording is supplied to the recording control unit 39, and the recording is stopped.

  If it is determined in step S15 that the volume level of the ambient sound is less than the high level, it is determined that the correct warning sound cannot be transmitted because the speaker or the microphone is blocked. Is canceled.

  The warning sound output control process is executed as described above. Although the large level in step S12 is adopted as the reference value for comparison in step S15, a value different from that in step S12 may be adopted as the comparison reference value in step S15.

  According to the above warning sound output control process, the control unit 13 of the video camera 1 warns that a moving image is being shot when it is recognized that a person is included in the shot image during the moving image shooting. Control to output sound. In addition, the control unit 13 of the video camera 1 determines whether or not the person recognized in the captured image is a person registered in the white list, and when a person not registered in the white list is detected. In addition, a control is performed to output a warning sound notifying that a movie is being shot. As a result, it is possible to appropriately warn a person who needs a warning in the vicinity of the photographer, to suppress unnecessary (unpleasant) warning sound, and to reduce the discomfort at the time of shooting. Can do.

  The video camera 1 can generate a warning sound if it can be recognized as a person from the captured image even if the distance to the warning target person is far away or the captured image is slightly out of focus.
