Abstract
Description
人感センサーを備えた表示装置では、表示装置の前に使用者がいることを検出し、検出結果に応じて表示装置を制御する。人感センサーは、表示装置の表示画面とは異なる場所に設置されている。通常は表示装置の表示画面中心を基準として検知するため、人感センサーは表示画面中心を通る垂線上付近の表示画面周縁に配置される。図6では、表示画面101が横向きであり、表示画面中心を通る垂線上付近であって、表示画面の水平方向(長辺側)の辺のうち、下方の辺の周縁部に人感センサー102が設けられる。
一方で使用者が当該表示装置を縦向きの状態で使用した場合、縦向きになることで表示装置の短辺と長辺の位置が変わる。そのため、図7に示すように、人感センサー102は、表示画面101の長辺上に位置することになり、表示画面中心を通る垂線上から外れる。これにより、人感センサー102の検出範囲の中心が表示画面の中心上から外れる。そのため、人感センサー102の検出範囲104は、表示装置の前面にいる使用者103を正しく検出する精度が低下してしまい、使用者が表示装置正面にいても、使用者が不在であると誤判断されてしまう。
図1は、本実施形態における表示装置1の構成を表す機能ブロック図である。
表示部10は、画像を表示する。この表示部10の表示画面は、矩形状である。この表示部10は、表示装置1に、回転ヒンジ付きスタンドによって取り付けられている。この回転ヒンジ付きスタンドは、表示部10を表示装置1に連結する機構であり、表示装置1を設置した際、ユーザによって表示部10を縦向きか横向きかを選択して切り替えることができる機構である。縦向きとは、表示画面の長手方向の辺が垂直方向であり、短手方向の辺が水辺方向である向きである。また、縦向きの状態は、ポートレートともいう。横向きとは、表示画面の長手方向の辺が水平方向であり、短手方向の辺が垂直方向である向きである。また、横向きの状態は、ランドスケープともいう。
第2人感センサー12は、表示部10の短手方向の辺に設けられる。
第1人感センサー11及び第2人感センサー12は、自身の検知範囲にユーザが存在するか否かを検出し、ユーザの存在有無を表す検出結果を出力するセンサーである。
この表示画面検出部13は、例えば、加速度センサーが用いられる。この加速度センサーは、重力を検出することで、表示部10の画面が縦向きであるか横向きであるかを検出することができる。
この制御部15は、第1人感センサー11または第2人感センサー12の検出結果において、表示部10の近傍にユーザがいることを検出した場合に、表示部10に画像を表示し、表示部10の近傍にユーザがいないことを検出した場合に、表示部10に画像を表示しないように制御する。
センサー電源切り替えスイッチ17は、表示画面検出部13の検出結果に応じて、第1人感センサー11または第2人感センサー12のいずれかに電源16から供給される電力を供給するように切り替える切り替えスイッチを有する。
具体的に、センサー電源切り替えスイッチ17は、表示画面検出部13の検出結果が横向きである場合、第1人感センサー11側にスイッチを切り替えて電源を供給し、表示画面検出部13の検出結果が縦向きである場合、第2人感センサー12側にスイッチを切り替えて電源を供給する。
表示部10は、表示装置1の正面側に設けられ、表示画面検出部13は、表示装置1の背面側に設けられる。また、第1人感センサー11は、表示部10の長辺側の一辺に設けられ、第2人感センサー12は、表示部10の短辺側の一辺に設けられる。
この図において、表示装置1は、表示部10の長辺側に第1人感センサー11、短辺側に第2人感センサー12が設けられている。この場合、第1人感センサー11は、第1人感センサー11の検出可能な範囲である検出範囲20内に、ユーザ21が存在するか否かを検出する。
この図において、表示装置1は、表示部10の長辺側に第1人感センサー11、短辺側に第2人感センサー12が設けられている。この場合、第2人感センサー12が、第2人感センサー12の検出可能な範囲である検出範囲22内に、ユーザ21が存在するか否かを検出する。
まず、表示装置1の表示画面検出部13は、表示部10の向きを検出し(ステップS11)、横向きであるか否かを判定し(ステップS12)、判定結果を含む、向きの検出結果をセンサー出力切り替えスイッチ14とセンサー電源切り替えスイッチ17とに出力する。
また、「コンピュータ読み取り可能な記録媒体」とは、フレキシブルディスク、光磁気ディスク、ROM、CD-ROM等の可搬媒体、コンピュータシステムに内蔵されるハードディスク等の記憶装置のことをいう。さらに「コンピュータ読み取り可能な記録媒体」とは、サーバやクライアントとなるコンピュータシステム内部の揮発性メモリのように、一定時間プログラムを保持しているものを含むものとする。また上記プログラムは、前述した機能の一部を実現するためのものであっても良く、さらに前述した機能をコンピュータシステムにすでに記録されているプログラムとの組み合わせで実現できるものであってもよい。また、上記のプログラムを所定のサーバに記憶させておき、他の装置からの要求に応じて、当該プログラムを通信回線を介して配信(ダウンロード等)させるようにしてもよい。
