Description
即ち、記録の必要性の低い場合でも記録が開始され、例えば撮像装置の記録容量を不必要に消費するという課題があった。
本発明は前述の問題点に鑑み、特定音声の検知結果に基づいて映像記録を開始する機能を備えた撮像装置において、より記録の必要性に則した記録が行えるようにすることを目的とする。
That is, even when the necessity for recording is low, the recording is started, and there is a problem that, for example, the recording capacity of the imaging apparatus is unnecessarily consumed.
Purpose of the present invention has been made in view of the problems described above, in the imaging apparatus having a function of starting the video recording based on Japanese Teioto voice detection result, to allow the recording to a more conforming to the needs of the recording And
本発明の撮像装置は、撮像画像と音情報を取得する取得手段と、前記取得手段により取得された音情報に所定音が含まれることを検知する検知手段と、前記検知手段による前記所定音の検知結果に応じて、前記撮像画像と前記音情報とメタデータのうち少なくとも１つの情報の記録を開始させる記録制御手段とを有し、前記記録制御手段は、前記少なくとも１つの情報の記録中に前記所定音の音量が所定の閾値以下になった場合、前記所定音の音量の減少率が所定の減少率以上であると、前記少なくとも１つの情報の記録を継続させ、前記所定音の音量の減少率が所定の減少率以上でないと、前記少なくとも１つの情報の記録を停止させることを特徴とする。 Imaging apparatus of the present invention includes an acquisition unit that acquires a captured image and sound information, and detection means for detecting that includes the obtained sound information Tokoro Teioto by the acquisition unit, wherein the predetermined sound by said detecting means Recording control means for starting recording of at least one of the captured image, the sound information, and the metadata in accordance with the detection result , wherein the recording control means is recording the at least one information. When the volume of the predetermined sound is equal to or lower than a predetermined threshold, the recording of the at least one information is continued if the rate of decrease in the volume of the predetermined sound is equal to or greater than a predetermined rate, and the volume of the predetermined sound is When the reduction rate of not more than a predetermined reduction rate, and wherein the Rukoto to stop recording of said at least one information.
本発明によれば、より記録の必要性の高い場合のみ記録を行うことが可能となり、記録容量を不必要に消費されるのを防止することができる。 According to the present invention, only it is possible to perform recording if highly necessary for good Ri recording, the recording capacity can be prevented from being consumed unnecessarily.
前述のようにすることで、特定パターン音声の検知音量が、第１の閾値以上になってから、所定の減少率以下で、第１の閾値より小さい第２の閾値未満になった場合、或いは、特定パターン音声の検知音量が第１の閾値以上になってから、所定の減少率以上で、第２の閾値未満になった場合とで、記録の期間が異なるように制御することができる。 By doing as described above, when the detected sound volume of the specific pattern sound becomes equal to or higher than the first threshold value and becomes lower than the second threshold value less than the first threshold value at a predetermined decrease rate or below , or The recording period can be controlled differently when the detected sound volume of the specific pattern sound is equal to or higher than the first threshold value and when it is equal to or higher than a predetermined decrease rate and lower than the second threshold value.
以上の処理により、例えば緊急自動車が特定パターンの音声の音源であった場合、緊急自動車が監視カメラ１００の周辺に停止し事件の発生確率が高いと思われる場合、或いは、近辺を通過した場合とで、録画時間を異なるよう制御することができ、より必要性の高い録画を行うことができる。これによって、例えば監視カメラ１００の記録容量を不必要に消費するという課題を解決することができる。 By the above processing, for example, when an emergency car is a sound source of a specific pattern, when an emergency car stops around the surveillance camera 100 and the probability of occurrence of an incident is high , or when it passes through the vicinity Thus, the recording time can be controlled to be different, and more highly necessary recording can be performed. Thereby, for example, the problem of unnecessarily consuming the recording capacity of the monitoring camera 100 can be solved.
前述のようにすることで、所定のパターンの条件の音（所定音）の音量が、第１の閾値より小さい第２の閾値以上になってから、所定の増加率以上で、第１及び第２の閾値以上になった場合、或いは、所定のパターンの条件の音の音量が、第２の閾値以上になってから、所定の増加率以下で、第１及び第２の閾値以上になった場合とで、記録の期間が異なるように制御することができる。 By doing as described above, after the volume of the sound of the predetermined pattern condition (predetermined sound) becomes equal to or higher than the second threshold value which is smaller than the first threshold value, the first and first values are increased at a predetermined increase rate or higher. If equal to or greater than second threshold value, or the volume of the sound conditions of the predetermined pattern, after becoming equal to or higher than the second threshold, below a predetermined increase rate, equal to or greater than the first and second threshold In some cases, the recording period can be controlled to be different.
