Abstract
Description
本発明が解決しようとする課題は、電力消費を抑制しつつ、室内の情報を任意に取得することができるカメラ装置、室内撮像システム、室内情報取得装置を提供することにある。
図1に示すように、本実施形態の室内撮像システム100は、家電製品としての冷蔵庫1、室内を撮像するためのカメラ装置2、冷蔵庫1側との間で通信を行うためのアクセスポイント3、操作端末としての携帯端末4等により構成されている。このうち、アクセスポイント3は、外部ネットワーク5に接続しており、外部ネットワーク5を介して遠隔地の携帯端末4やサーバ6等と冷蔵庫1側との間を通信可能に接続している。本実施形態では、冷蔵庫1とアクセスポイント3との間、アクセスポイント3と携帯端末4との間、およびカメラ装置2とアクセスポイント3との間は、Bluetooth(登録商標)による無線通信にて通信が行われる。
カメラ装置2は、図2および図3に示すように、概ね直方体の形状に形成された筐体10の表面に、撮像部11(図4参照)のレンズ12、本実施形態では2個の撮像ライト13、および光センサ14が露出するように設けられている。ただし、レンズ12や撮像ライト13および光センサ14は、筐体10外に露出するのではなく、その表面がカバー等で覆われた態様であってもよい。以下、レンズ12等が露出している側を(図3の図示右方側)をカメラ装置2の正面とし、反対側(図3の図示左方側)を背面として説明する。
上記したカメラ装置2を設けることにより、住宅7の室内や冷蔵室等の室内を撮像することができる。この場合、外部ネットワーク5を経由して携帯端末4からカメラ装置2に対して撮像指示を送信することで、遠隔地からであっても任意のタイミングで撮像データを取得することができる。ただし、いつ撮像指示が送られてくるかが不明なために通信モジュール17を常に動作させておく必要があり、その場合には電力消費が大きくなる。その結果、1日あるいは数日程度で電池16交換(あるいは充電)が必要となる。
光エネルギーを用いて撮像指示を伝達する場合、冷蔵庫1は図5に示す庫側処理を実行し、カメラ装置2は図6に示すカメラ側処理を実行する。
冷蔵庫1は、図5に示す庫側処理において、撮像指示を受信したかを判定する(R1)。ユーザからの撮像支持は、アクセスポイント3を経由して通信アダプタ34により冷蔵庫1にて受信される(図4参照)。冷蔵庫1は、撮像指示を受信していない場合には(R1:NO)、そのまま待機する。一方、冷蔵庫1は、撮像指示を受信した場合には(R1:YES)、扉が閉鎖されているかを判定し(R2)、扉が開放されている場合には(R2:NO)、扉が閉鎖されるまで待機する。
このように、スリープモード中のカメラ装置2に対して、光エネルギーにより撮像指示を伝達することができる。
音エネルギーを用いて撮像指示を伝達する場合、光エネルギーの場合と同様に、冷蔵庫1は図5に示す庫側処理を実行し、カメラ装置2は図6に示すカメラ側処理を実行する。以下、処理内容が異なる点について詳細に説明する。
このように、スリープモード中のカメラ装置2に対して、音エネルギーにより撮像指示を伝達することができる。
上記した光エネルギーと音エネルギーの場合には、ユーザがリアルタイムに撮像指示を送信する状況を想定したが、今回は、冷蔵庫1の扉が開閉されたとき(つまり、冷蔵庫1の貯蔵状態が変化した可能性があるとき)に撮像するという撮像指示が予め設定されている状況を想定している。すなわち、撮像指示を受信する受信手段とは、リアルタイムの撮像指示だけで無く、予め設定されている条件に基づいた撮像指示を受信する(受け付ける)ことも可能な構成となっている。
冷蔵庫1は、図9に示す庫側処理において、扉が開閉されたかを判定しており(R10)、扉が開閉されていない場合には(R10:NO)、待機する。一方、冷蔵庫1は、扉が開閉された場合には(R10:YES)、撮像中であることを報知した後(R11)、通信アダプタ34からカメラ装置2に対して撮像指示を送信する(R11)。
<光エネルギーと振動エネルギーとを用いる場合>
今回は、光エネルギーと振動エネルギーとを用い、冷蔵庫1の扉が開閉されたときに撮像するという撮像指示が予め設定されている状況において、カメラ装置2単体で撮像する例を説明する。このとき、カメラ装置2は、図11に示すカメラ側処理を実行する。なお、図11に示すカメラ側処理の流れは概ね図10に示したカメラ側処理と共通するので、異なる点について詳細に説明する。
a)光エネルギーを検出している期間が、瞬間的なものでは無く、物品等を取り出すのに要する程度の期間であったか。
b)扉が閉鎖された際の振動エネルギーを検出したか。
このように、スリープモード中のカメラ装置2に対して、光エネルギーと振動エネルギーとを組み合わせることによっても撮像指示を伝達することができる。
カメラ装置2は、室内を撮像する撮像部11と、撮像指示を家電製品を介して受信する受信手段と、常には通常動作モードよりも相対的に電力消費が少ない低電力モードにて待機しており、受信手段で撮像指示が受信されると通常動作モードに復帰して撮像手段により室内を撮像する制御を行うカメラ側制御部18と、を備えているので、撮像指示がいつ送信されるかが想定できない場合であっても、通常動作状態のまま待機する必要が無い。これにより、待機中の電力消費を削減することができる。また、受信手段を設けているので、いつ撮像指示が送信されても室内を撮像することができる。したがって、電力消費を抑制しつつ、室内の情報である撮像データを任意に取得することができる。
撮像が終了したとき、および、検出されたエネルギーのパターンと撮像指示を示すパターンとが一致しなかったときにはスリープモード(低電力モード)に移行するので、電力消費を低減することができる。
上記した実施形態にて例示した構成は、それに限定されることなく、例えば以下に示すような変形や組み合わせの変更等を行うことができる。そして、それらの構成によっても、一実施形態と同様の効果を得ることができる。
その場合、人の可聴域を超える波長域(例えば、20kHz程度以上)の超音波を用いれば、ユーザが在宅中でも音の発生を気にすることが無くなる。また、パネルブザー29や室内ブザー33を用いることなく、上記した送風機31を通常運転では使用しない回転数(例えば2500rpm)まで上げて音エネルギーを発生させてもよい。
一実施形態では光エネルギーと振動エネルギーとを組み合わせた例を示したが、光エネルギーと音エネルギーとを組み合わせてもよいし、音エネルギーと振動エネルギーとを組み合わせてもよいし、それら全てを組み合わせてもよい。勿論、冷蔵庫1の扉が開閉されたときに撮像するという撮像指示が予め設定されている場合だけでなく、リアルタイムで送信された撮像指示を伝達する際にも各エネルギーを組み合わせて伝達するようにしてもよい。
