Description

表示パネルを制御するシステムDisplay panel control system

　本開示は、表示パネルの使用電力を低減するシステムに関する。 This disclosure relates to a system that reduces the power consumption of a display panel.

　通信用端末、コンピュータ、テレビなどの様々な装置に、用途に合わせた様々な表示パネルが備わっている。このように、市中には様々な表示パネルが存在する。表示パネルの多くは、バックライトを発光させることで表示を行う。このバックライトでの使用電力は、装置の省電力性能に多大な影響を及ぼす。そこで、表示パネルの使用電力を低減する方法が提案されている（例えば、非特許文献１参照。）。 Various devices, such as communication terminals, computers, and televisions, are equipped with various display panels suited to their applications. As such, there are a variety of display panels on the market. Many display panels display information by emitting light from a backlight. The power used by this backlight has a significant impact on the power saving performance of the device. As a result, methods have been proposed for reducing the power used by display panels (see, for example, Non-Patent Document 1).

　非特許文献１では、表示パネルの視線を検出し、表示パネルのうちの視線で定められる領域のみ表示する。これにより、非特許文献１では、表示パネルの表示領域以外での電力消費を防ぎ、表示パネルの使用電力を低減する。 In Non-Patent Document 1, the line of sight of the display panel is detected, and only the area of the display panel that is determined by the line of sight is displayed. In this way, Non-Patent Document 1 prevents power consumption outside the display area of the display panel, reducing the power consumption of the display panel.

Morikawa, “LCD display energy reduction by user monitoring,” 2005 Int International Conference on Computer Design, San Jose, CA, USA, 2005, pp. 94-97.

　しかし、非特許文献１では、視線の解析に時間を要するため、利用者の状態と表示パネルの表示との間に大きなタイムラグが生じる問題がある。一方で、視線の解析時間を短縮しようとすると、視線の解析結果に誤りが生じ、表示パネルの表示が利用者の状態と一致しなくなる問題がある。表示パネルの表示が利用者の状態と一致しない場合、利用者が見たいものが表示パネルに表示されなくなる。このため、利用者の視線による表示パネルの制御は、利用者に負担を感じさせる可能性があった。 However, in Non-Patent Document 1, gaze analysis takes time, which causes a problem of a large time lag between the user's state and the display on the display panel. On the other hand, if an attempt is made to shorten the gaze analysis time, there is a problem that errors will occur in the gaze analysis results, and the display on the display panel will not match the user's state. If the display on the display panel does not match the user's state, what the user wants to see will not be displayed on the display panel. For this reason, controlling the display panel based on the user's gaze could be a burden on the user.

　そこで、本開示は、利用者に負担を感じさせずに、表示パネルの使用電力を低減することを目的とする。 The present disclosure therefore aims to reduce the power consumption of display panels without imposing a burden on users.

　前記複数のセンサで得られたセンサ情報に基づいて、前記表示パネルの制御を行う制御装置と、
　を備える。 In order to achieve the above object, the system of the present disclosure comprises:
A plurality of sensors for detecting the state of a user of the display panel;
an information collecting unit that collects the sensor information obtained by the plurality of sensors and provides the information to the control device;
a control device that controls the display panel based on sensor information obtained by the plurality of sensors;
Equipped with.

　前記表示パネルの出力強度の制御は、例えば、前記センサ情報に基づいて予測される前記表示パネルの利用者の行動パターンに応じて、前記表示パネルの出力強度を制御する。このため、本開示は、利用者に負担を感じさせずに、表示パネルの使用電力を低減することができる。 The output intensity of the display panel is controlled, for example, according to the behavior pattern of the user of the display panel predicted based on the sensor information. Therefore, the present disclosure can reduce the power consumption of the display panel without causing a burden to the user.

　　前記センサ情報は、
　（ｉ）前記表示パネルの利用者の周囲の音が検出された音情報、
　（ｉｉ）前記表示パネルの利用者の周囲の光が検出された光情報、
　（ｉｉｉ）前記表示パネルの利用者の利用する物への圧力が検出された圧力情報、
　（ｉｖ）前記表示パネルに接続されている電子計算機における画面情報、
　（ｖ）前記表示パネルに接続されている電子計算機で実行されているアプリケーション情報、
　の少なくともいずれかを含んでいてもよい。
　この場合、前記制御装置は、前記音情報、前記光情報、前記圧力情報、前記画面情報及び前記アプリケーション情報のそれぞれに定められるパラメータを用いて、前記表示パネルの出力強度を決定する。 The sensor information includes:
(i) sound information of sounds detected around a user of the display panel;
(ii) light information about light detected around a user of the display panel;
(iii) pressure information in which pressure applied to an object used by a user of the display panel is detected;
(iv) screen information in a computer connected to the display panel;
(v) application information running on a computer connected to the display panel;
may include at least one of the above.
In this case, the control device determines the output intensity of the display panel using parameters defined for each of the sound information, the light information, the pressure information, the screen information, and the application information.

　なお、上記各開示は、可能な限り組み合わせることができる。 The above disclosures may be combined to the greatest extent possible.

　表示パネル９１の周囲で音が発生したとき、図３に示すように、音検出センサ５１が外部の音の発生を検出し、検出した音情報を情報収集部９４へ連携する（Ｓ１１１）。そして、情報収集部９４が音情報を含むセンサ情報を収集し、行動予測機能部２３へ連携する（Ｓ１１２）。行動予測機能部２３は、情報収集部９４から連携されたセンサ情報に基づいて、バックライト１１の出力強度を決定し、表示パネル制御部２２へ通知する（Ｓ１１３）。これにより、音情報に対応した出力強度に表示パネル９１の出力強度が制御される。 When sound is generated around the display panel 91, as shown in FIG. 3, the sound detection sensor 51 detects the generation of an external sound and shares the detected sound information with the information collection unit 94 (S111). The information collection unit 94 then collects sensor information including the sound information and shares it with the behavior prediction function unit 23 (S112). The behavior prediction function unit 23 determines the output intensity of the backlight 11 based on the sensor information shared by the information collection unit 94 and notifies the display panel control unit 22 (S113). This controls the output intensity of the display panel 91 to an output intensity corresponding to the sound information.

When the pressure on the object being used by the user of the display panel 91 changes, in step S111 shown in Figure 3, the pressure sensor 53 detects the change in pressure on the input device 31 or the chair 32, and transmits the detected pressure information to the information collection unit 94.

　行動予測機能部２３は、情報収集部９４から連携された音情報、光情報、圧力情報、画面情報及びアプリケーション情報の全てに基づいて、バックライト１１の出力強度を決定する。例えば、行動予測機能部２３は、図４に示すような、情報ごとのパラメータＬｓ、Ｌｌ、Ｌｐ、Ｌｄ、Ｌａを定める設定テーブルを参照し、パラメータＬｓ、Ｌｌ、Ｌｐ、Ｌｄ、Ｌａを用いてバックライト１１の出力強度を算出する。 The behavior prediction function unit 23 determines the output intensity of the backlight 11 based on all of the sound information, light information, pressure information, screen information, and application information linked from the information collection unit 94. For example, the behavior prediction function unit 23 refers to a setting table that defines parameters Ls, Ll, Lp, Ld, and La for each piece of information as shown in FIG. 4, and calculates the output intensity of the backlight 11 using the parameters Ls, Ll, Lp, Ld, and La.

　バックライト１１の出力強度ＬＳは、例えば、次式を用いて算出することができる。
（数１）
　ＬＳ＝Ｌｓ×Ｌｌ×Ｌｐ×Ｌｄ×Ｌａ　　（１）
　ここで、Ｌｓ、Ｌｌ、Ｌｐ、Ｌｄ、Ｌａは、バックライト１１の出力強度が１００％のときの出力強度ＬＳに対する強度の割合であり、以下のとおりである。
Ｌｓ：音情報で定められるパラメータである。

Here, Ls, Ll, Lp, Ld, and La are the ratios of intensity to the output intensity LS when the output intensity of the backlight 11 is 100%, as follows:
Ls: A parameter determined by sound information.
Ll: A parameter determined by light information.
Lp: A parameter determined by pressure information.
Ld: A parameter determined by the screen information.
La: A parameter defined in the application information.

　図５に、外部環境の影響を受けて、行動予測機能部２３がバックライト１１の出力強度を判定するフローの一例を示す。本実施形態では、手順Ｓ２１１、手順Ｓ２２１、手順Ｓ２３１、手順Ｓ２４１、手順Ｓ２５１、手順Ｓ２６１を順に実行する。
　音検出センサ５１が特定の音を検出しているときは（Ｓ２１１においてＹｅｓ）、Ｌｓを設定する（Ｓ２１２）。
　外部光検出センサ５２が特定の光を検出しているときは（Ｓ２２１においてＹｅｓ）、Ｌｌを設定する（Ｓ２２２）。
　圧力検出センサ５３が特定の圧力変化を検出しているときは（Ｓ２３１においてＹｅｓ）、Ｌｐを設定する（Ｓ２３２）。
　表示画面検出機能部５４が特定の画面状態を検出しているときは（Ｓ２４１においてＹｅｓ）、Ｌｄを設定する（Ｓ２４２）。
　アプリケーション検出機能部５５が特定のアプリケーション状態を検出しているときは（Ｓ２５１においてＹｅｓ）、Ｌａを設定する（Ｓ２５２）。 5 shows an example of a flow in which the behavior prediction function unit 23 is influenced by the external environment and determines the output intensity of the backlight 11. In this embodiment, steps S211, S221, S231, S241, S251, and S261 are executed in this order.
When the sound detection sensor 51 detects a specific sound (Yes in S211), Ls is set (S212).
When the external light detection sensor 52 detects the specific light (Yes in S221), L1 is set (S222).
When the pressure detection sensor 53 detects a specific pressure change (Yes in S231), Lp is set (S232).
When the display screen detection function unit 54 detects a specific screen state (Yes in S241), Ld is set (S242).
When the application detection function unit 55 detects a specific application state (Yes in S251), La is set (S252).

　手順Ｓ２６１では、行動予測機能部２３は、手順Ｓ２１２、手順Ｓ２２２、手順Ｓ２３２、手順Ｓ２４２、手順Ｓ２５２で設定されたパラメータを用いて、バックライト１１の出力強度ＬＳを算出する。表示パネル制御部２２は、行動予測機能部２３の出力強度ＬＳに従ってバックライト１１の出力強度を制御する。 In step S261, the behavior prediction function unit 23 calculates the output intensity LS of the backlight 11 using the parameters set in steps S212, S222, S232, S242, and S252. The display panel control unit 22 controls the output intensity of the backlight 11 according to the output intensity LS of the behavior prediction function unit 23.

　ここで、行動予測機能部２３は、センサ情報から予測される利用者の行動パターンに応じて、バックライト１１の出力強度を制御してもよい。行動パターンは、例えば、表示パネル９１への利用者の注意が逸れる第１のパターンであるのか、表示パネル９１の前から移動する第２のパターンであるのか、が例示できる。例えば、パトカーのサイレンのような音の場合、行動予測機能部２３は第１のパターンと判定する。乳幼児の泣き声やアラームの音の場合、行動予測機能部２３は第２のパターンと判定する。 Here, the behavior prediction function unit 23 may control the output intensity of the backlight 11 according to the behavior pattern of the user predicted from the sensor information. Examples of the behavior pattern include a first pattern in which the user's attention is diverted from the display panel 91, and a second pattern in which the user moves away from in front of the display panel 91. For example, in the case of a sound like a police siren, the behavior prediction function unit 23 determines it to be the first pattern. In the case of a crying baby or the sound of an alarm, the behavior prediction function unit 23 determines it to be the second pattern.

　図４に示す設定テーブルでは、音情報、圧力情報及び画面情報において２つの行動パターンが設定されている。そのため、手順Ｓ２１２、Ｓ２３２、Ｓ２４２において、行動予測機能部２３はどちらの行動パターンであるのかを判定する。例えば、図６に示すように、手順Ｓ２１２において、行動予測機能部２３は、第１のパターンの音情報であればＬｓを８０％に設定し、第２のパターンの音情報であればＬｓを５０％に設定する。手順Ｓ２３２及びＳ２４２においても同様である。これらはパラメータの値も含めてあくまで例であり、パターン数も３パターン以上存在してもよい。さらに本開示では、制御に用いるセンサ情報の種類に応じて加重を与えることで、表示パネル９１の出力強度を段階的に制御してもよい。 In the setting table shown in FIG. 4, two behavioral patterns are set for sound information, pressure information, and screen information. Therefore, in steps S212, S232, and S242, the behavior prediction function unit 23 determines which behavioral pattern it is. For example, as shown in FIG. 6, in step S212, the behavior prediction function unit 23 sets Ls to 80% if the sound information is the first pattern, and sets Ls to 50% if the sound information is the second pattern. The same is true for steps S232 and S242. These are merely examples, including the parameter values, and there may be three or more patterns. Furthermore, in the present disclosure, the output intensity of the display panel 91 may be controlled in stages by applying weighting according to the type of sensor information used for control.

　以上説明したように、本開示のシステムは、センサ情報で得られる利用者の情報に基づいて表示パネル９１の利用者の行動を予測し、予測に基づいてバックライト１１の出力強度を制御する。本実施形態では、利用者の行動に応じて表示パネル９１の使用電力を抑制するため、表示パネル９１の使用電力を低減することができる。 As described above, the system disclosed herein predicts the behavior of the user of the display panel 91 based on the user information obtained from the sensor information, and controls the output intensity of the backlight 11 based on the prediction. In this embodiment, the power consumption of the display panel 91 is suppressed according to the user's behavior, so that the power consumption of the display panel 91 can be reduced.

（第２の実施形態）
　本開示のシステムは、利用者の視線によって表示パネル９１の表示を制御してもよい。例えば、本実施形態のシステムは、図７に示すように、視線検出センサ９３を備え、制御装置９２が視線位置判定部２１を備えていてもよい。 Second Embodiment
The system of the present disclosure may control the display on the display panel 91 according to the line of sight of the user. For example, the system of the present embodiment may include a line of sight detection sensor 93, and the control device 92 may include a line of sight position determination unit 21, as shown in FIG.

　図８に、本実施形態のシステムの動作の一例を示す。視線検出センサ９３が表示パネル９１の利用者の視線情報を検出し、検出した視線情報を視線位置判定部２１へ連携する（Ｓ２０１）。 FIG. 8 shows an example of the operation of the system of this embodiment. The gaze detection sensor 93 detects gaze information of the user on the display panel 91, and transmits the detected gaze information to the gaze position determination unit 21 (S201).

　視線位置判定部２１は、視線検出センサ９３の視線情報から表示パネル９１の利用者の視線位置を判定し、視線情報に応じた表示領域ＤＩを決定する（Ｓ２０２）。これにより、表示領域ＤＩ及び非表示領域ＤＯが決定される。表示領域ＤＩの情報は表示パネル制御部２２に連携される。表示パネル制御部２２は、視線位置判定部２１から受け取る表示領域ＤＩを、行動予測機能部２３から受け取るバックライト１１の出力強度で表示するよう、バックライト１１を制御する（Ｓ２０３）。 The gaze position determination unit 21 determines the gaze position of the user on the display panel 91 from the gaze information of the gaze detection sensor 93, and determines the display area D I according to the gaze information (S202). This determines the display area D I and the non-display area D O. The information on the display area D I is linked to the display panel control unit 22. The display panel control unit 22 controls the backlight 11 so that the display area D I received from the gaze position determination unit 21 is displayed at the output intensity of the backlight 11 received from the behavior prediction function unit 23 (S203).

　表示パネル９１が有するバックライト１１は、表示パネル制御部２２から連携された表示領域ＤＩを発光し、非表示領域ＤＯを発光しない（Ｓ２０４）。このとき、バックライト１１は、表示パネル制御部２２から連携された出力強度に従い、表示パネル制御部２２から連携された表示領域ＤＩの出力強度を制御する。これにより、液晶パネル１２は、表示領域ＤＩを表示パネル制御部２２から連携された出力強度で表示する（Ｓ２０５）。 The backlight 11 of the display panel 91 emits light to the display area D I coordinated by the display panel control unit 22, and does not emit light to the non-display area D O (S204). At this time, the backlight 11 controls the output intensity of the display area D I coordinated by the display panel control unit 22 according to the output intensity coordinated by the display panel control unit 22. As a result, the liquid crystal panel 12 displays the display area D I at the output intensity coordinated by the display panel control unit 22 (S205).

　以上説明したように、本実施形態では、表示パネル９１の利用者の視線情報に基づいて非表示領域ＤＯを生じさせる。このため、本実施形態では、第１の実施形態での省電力効果に加え、さらに表示パネル９１の使用電力を低減することができる。 As described above, in this embodiment, the non-display area D O is generated based on the line-of-sight information of the user of the display panel 91. Therefore, in this embodiment, in addition to the power-saving effect of the first embodiment, it is possible to further reduce the power consumption of the display panel 91.

（第３の実施形態）
　図９を参照しながら、音情報に基づいて表示パネル９１の制御を行う例を説明する。表示領域ＤＩの出力強度は１００％、非表示領域ＤＯの出力強度は０％であり、静かな状態で利用者が表示パネル９１を視聴している。このとき、表示パネル９１の利用者の視線で限定される表示領域Ｄ１のみで表示される。表示領域Ｄ１は、視線検出センサ９３で得られた視線情報をもとに決定される。 Third Embodiment
An example of controlling the display panel 91 based on sound information will be described with reference to Fig. 9. The output intensity of the display area D1 is 100%, and the output intensity of the non-display area D0 is 0%, and the user is watching the display panel 91 in a quiet state. At this time, only the display area D1 , which is limited by the line of sight of the user of the display panel 91, is displayed. The display area D1 is determined based on line-of-sight information obtained by the line-of-sight detection sensor 93.

　乳幼児の泣き声が音検出センサ５１で検出されると、その音情報が情報収集部９４で収集され、制御装置９２に連携される。乳幼児の泣き声は第２のパターンに設定されている。このため、制御装置９２は、図４に示す設定テーブルを参照し、Ｌｓを５０％に設定する。これにより、制御装置９２は、表示領域Ｄ１の内側での出力強度を５０％に下げる。 When the sound detection sensor 51 detects the crying of an infant, the sound information is collected by the information collection unit 94 and is linked to the control device 92. The crying of an infant is set to the second pattern. Therefore, the control device 92 refers to the setting table shown in Fig. 4 and sets Ls to 50%. As a result, the control device 92 reduces the output intensity inside the display area D1 to 50%.

　なお、ここでは代表して音検出センサ５１のみ図示しており、情報収集部９４には種々のセンサ情報が収集される。また、乳幼児の泣き声を第２のパターンとしたが、行動パターンの種類及びパラメータＬｓは任意の値を採用しうる。 Note that only the sound detection sensor 51 is shown here as a representative example, and various sensor information is collected by the information collection unit 94. Also, although the crying of an infant is set as the second pattern, any value can be used for the type of behavior pattern and the parameter Ls.

（第４の実施形態）
　図１０を参照しながら、光情報に基づいて表示パネル９１の制御を行う例を説明する。変化前の表示領域ＤＩ及び非表示領域ＤＯの出力強度は、第３の実施形態と同様である。部屋の照明を消したことが外部光検出センサ５２で検出されると、その光情報が情報収集部９４で収集され、制御装置９２に連携される。光強度の低下は第１のパターンに設定されている。このため、制御装置９２は、図４に示す設定テーブルを参照し、Ｌｌを８０％に設定する。これにより、制御装置９２は、表示領域Ｄ１の内側での出力強度を８０％に下げる。 Fourth Embodiment
With reference to FIG. 10, an example of controlling the display panel 91 based on light information will be described. The output intensity of the display area D1 and the non-display area D0 before the change is the same as that of the third embodiment. When the external light detection sensor 52 detects that the room lights have been turned off, the light information is collected by the information collection unit 94 and communicated to the control device 92. The reduction in light intensity is set to the first pattern. Therefore, the control device 92 refers to the setting table shown in FIG. 4 and sets L1 to 80%. As a result, the control device 92 reduces the output intensity inside the display area D1 to 80%.

　なお、ここでは代表して外部光検出センサ５２のみ図示しており、情報収集部９４には種々のセンサ情報が収集される。また、光強度の低下を第１のパターンとしたが、行動パターンの種類及びパラメータＬｌは任意の値を採用しうる。 Note that only the external light detection sensor 52 is shown here as a representative example, and various sensor information is collected by the information collection unit 94. Also, although a decrease in light intensity is set as the first pattern, any value can be adopted for the type of behavior pattern and the parameter Ll.

（第５の実施形態）
　図１１を参照しながら、圧力情報に基づいて表示パネル９１の制御を行う例を説明する。変化前の表示領域ＤＩ及び表示領域外ＤＯの出力強度は、第３の実施形態と同様である。利用者が離席すると、椅子３２への圧力が低下したことを圧力検出センサ５３で検出されると、その圧力情報が情報収集部９４で収集され、制御装置９２に連携される。椅子３２への圧力の低下は第２のパターンに設定されている。この場合、制御装置９２は、図４に示す設定テーブルを参照し、Ｌｐを７０％に設定する。これにより、制御装置９２は、表示領域Ｄ１の内側での出力強度を７０％に下げる。 Fifth Embodiment
An example of controlling the display panel 91 based on pressure information will be described with reference to FIG. 11. The output intensity of the display area D1 and outside the display area D0 before the change is the same as that of the third embodiment. When the user leaves the seat, the pressure detection sensor 53 detects that the pressure on the chair 32 has decreased, and the pressure information is collected by the information collection unit 94 and communicated to the control device 92. The decrease in pressure on the chair 32 is set to the second pattern. In this case, the control device 92 refers to the setting table shown in FIG. 4 and sets Lp to 70%. As a result, the control device 92 reduces the output intensity inside the display area D1 to 70%.

　なお、ここでは代表して圧力検出センサ５３のみ図示しており、情報収集部９４には種々のセンサ情報が収集される。また、椅子３２への圧力が低下したことを圧力情報の第２のパターンとしたが、行動パターンの種類及びパラメータＬｐは任意の値を採用しうる。 Note that only the pressure detection sensor 53 is shown here as a representative example, and various sensor information is collected by the information collection unit 94. Also, although a decrease in pressure on the chair 32 is set as the second pattern of pressure information, any value can be adopted for the type of behavior pattern and the parameter Lp.

When the user releases the mouse of the electronic computer 33 and the screen of the electronic computer 33 becomes the top image of the desktop, the pressure information of the mouse and the screen information at this time are collected by the information collecting unit 94.

　電子計算機３３のマウスから手を放す動作は圧力情報の第１のパターンに設定されている。またデスクトップのトップ画像は画面情報の第２のパターンに設定されている。制御装置９２は、図４に示す設定テーブルを参照し、Ｌｐを９０％に、Ｌｄを３０％に設定する。これにより、制御装置９２は、表示領域Ｄ１の内側での出力強度を９０×３０＝２７［％］まで下げる。 The action of releasing the mouse of the electronic calculator 33 is set to the first pattern of pressure information. The top image of the desktop is set to the second pattern of screen information. The control device 92 refers to the setting table shown in Fig. 4 and sets Lp to 90% and Ld to 30%. As a result, the control device 92 reduces the output intensity inside the display area D1 to 90 x 30 = 27%.

　なお、ここでは代表して圧力検出センサ５３及び表示画面検出機能部５４のみ図示しており、情報収集部９４には種々のセンサ情報が収集される。また電子計算機３３のマウスから手を放したときの圧力情報を第１のパターンとし、デスクトップのトップ画像に変化したときの画面情報を第２のパターンとしたが、行動パターンの種類及びパラメータＬｐ及びＬｄは任意の値を採用しうる。 Note that here, only the pressure detection sensor 53 and the display screen detection function unit 54 are shown as representatives, and various sensor information is collected by the information collection unit 94. Also, the pressure information when the mouse of the electronic computer 33 is released is set as the first pattern, and the screen information when the top image of the desktop is displayed is set as the second pattern, but the type of behavior pattern and the parameters Lp and Ld can adopt any values.

The output intensity of the display area D I and the outside of the display area D O before the change is the same as in the third embodiment. When the wireless communication of the electronic computer 33 is cut off and the Web conference screen of the electronic computer 33 ends, the application information and screen information at this time are collected by the information collecting unit 94.

　無線通信が切れるアプリケーション情報は第１のパターンに設定されている。またＷｅｂ会議の画面が終了する画面情報は画面情報の第１のパターンに設定されている。制御装置９２は、図４に示す設定テーブルを参照し、Ｌｄを５０％に、Ｌａを８０％に設定する。これにより、制御装置９２は、表示領域Ｄ１の内側での出力強度を５０×８０＝４０［％］まで下げる。 The application information for which wireless communication is to be terminated is set to the first pattern. Also, the screen information for which the Web conference screen is to be terminated is set to the first pattern of screen information.
