And the control part 100 can perform the process according to the specified operation content. Note that instead of the display panel 122 and the touch panel 130, an in-cell display panel in which a touch panel is incorporated may be employed.
　操作ボタン群１４０の各操作ボタンは、ユーザによって操作されると、操作されたことを示す操作信号を制御部１００に出力することが可能である。これにより、制御部１００は、各操作ボタンについて、当該操作ボタンが操作されたか否かを判断することができる。操作信号が入力された制御部１００が他の構成要素を制御することによって、電子機器１では、操作された操作ボタンに割り当てられている機能が実行される。 When each operation button of the operation button group 140 is operated by a user, an operation signal indicating that the operation button is operated can be output to the control unit 100. Thereby, the control part 100 can judge whether the said operation button was operated about each operation button. When the control unit 100 to which the operation signal is input controls other components, the electronic device 1 executes a function assigned to the operated operation button.
　マイク１８０は、電子機器１の外部から入力される音を電気的な音信号に変換して制御部１００に出力することが可能である。電子機器１の外部からの音は、マイク穴１４から電子機器１の内部に取り込まれてマイク１８０に入力される。 The microphone 180 can convert a sound input from the outside of the electronic device 1 into an electrical sound signal and output it to the control unit 100. Sound from the outside of the electronic device 1 is taken into the electronic device 1 from the microphone hole 14 and input to the microphone 180.
　スピーカ１７０は、例えばダイナミックスピーカである。スピーカ１７０は、制御部１００からの電気的な音信号を音に変換して出力することが可能である。スピーカ１７０から出力される音は、スピーカ穴１３から外部に出力される。ユーザは、スピーカ穴１３から出力される音を、電子機器１から離れた場所でも聞こえることが可能である。 The speaker 170 is, for example, a dynamic speaker. The speaker 170 can convert an electrical sound signal from the control unit 100 into a sound and output the sound. Sound output from the speaker 170 is output from the speaker hole 13 to the outside. The user can hear the sound output from the speaker hole 13 even at a location away from the electronic device 1.
　レシーバ１６０は受話音を出力することが可能である。レシーバ１６０は例えばダイナミックスピーカである。レシーバ１６０は、制御部１００からの電気的な音信号を音に変換して出力することが可能である。レシーバ１６０から出力される音はレシーバ穴１２から外部に出力される。レシーバ穴１２から出力される音の音量は、スピーカ穴１３から出力される音の音量よりも小さくなっている。ユーザは、レシーバ穴１２から出力される音を、当該レシーバ穴１２に耳を近づけることによって聞くことができる。なお、レシーバ１６０の代わりに、機器ケース１１の前面部分を振動させる、圧電振動素子等の振動素子を設けてもよい。この場合には、音は、当該前面部分の振動によりユーザに伝達される。 The receiver 160 can output a received sound. The receiver 160 is a dynamic speaker, for example. The receiver 160 can convert an electrical sound signal from the control unit 100 into a sound and output the sound. The sound output from the receiver 160 is output from the receiver hole 12 to the outside. The volume of the sound output from the receiver hole 12 is smaller than the volume of the sound output from the speaker hole 13. The user can hear the sound output from the receiver hole 12 by bringing his ear close to the receiver hole 12. Instead of the receiver 160, a vibration element such as a piezoelectric vibration element that vibrates the front surface portion of the device case 11 may be provided. In this case, the sound is transmitted to the user by the vibration of the front portion.
　第１カメラ１９０は、レンズ１９１及びイメージセンサなどを備えている。第２カメラ２００は、レンズ２０１及びイメージセンサなどを備えている。第１カメラ１９０及び第２カメラ２００のそれぞれは、制御部１００による制御に基づいて被写体を撮影し、撮影した被写体を示す静止画あるいは動画を生成して制御部１００に出力することが可能である。 The first camera 190 includes a lens 191 and an image sensor. The second camera 200 includes a lens 201 and an image sensor. Each of the first camera 190 and the second camera 200 can photograph a subject based on control by the control unit 100, generate a still image or a moving image indicating the photographed subject, and output the still image or moving image to the control unit 100. .
　第１カメラ１９０のレンズ１９１は、機器ケース１１の前面１１ａから視認可能となっている。したがって、第１カメラ１９０は、電子機器１の前面側（表示画面１２１側）に存在する被写体を撮影することが可能である。第１カメラ１９０はインカメラと呼ばれる。一方で、第２カメラ２００のレンズ２０１は、機器ケース１１の背面１１ｂから視認可能となっている。したがって、第２カメラ２００は、電子機器１の背面側に存在する被写体を撮影することが可能である。第２カメラ２００はアウトカメラと呼ばれる。 The lens 191 of the first camera 190 is visible from the front surface 11 a of the device case 11. Therefore, the first camera 190 can shoot a subject existing on the front side (display screen 121 side) of the electronic device 1. The first camera 190 is called an in camera. On the other hand, the lens 201 of the second camera 200 is visible from the back surface 11 b of the device case 11. Therefore, the second camera 200 can capture a subject existing on the back side of the electronic device 1. The second camera 200 is called an out camera.
　加速度センサ１５０は、電子機器１の加速度を検出することが可能である。加速度センサ１５０は例えば３軸加速度センサである。加速度センサ１５０は、Ｘ軸方向、Ｙ軸方向及びＺ軸方向（図１，２参照）の電子機器１の加速度を検出することが可能である。 The acceleration sensor 150 can detect the acceleration of the electronic device 1. The acceleration sensor 150 is, for example, a three-axis acceleration sensor. The acceleration sensor 150 can detect the acceleration of the electronic device 1 in the X-axis direction, the Y-axis direction, and the Z-axis direction (see FIGS. 1 and 2).
　電池２１０は電子機器１の電源を出力することが可能である。電池２１０は例えば充電式の電池である。電池２１０から出力される電源は、電子機器１が備える制御部１００及び無線通信部１１０などの各種構成に対して供給される。 The battery 210 can output the power of the electronic device 1. The battery 210 is, for example, a rechargeable battery. The power output from the battery 210 is supplied to various components such as the control unit 100 and the wireless communication unit 110 included in the electronic device 1.
　なお電子機器１は、加速度センサ１５０を備えなくてもよい。この場合、電子機器１は、それとは別体の加速度センサと、無線あるいは有線で接続されてよい。 Note that the electronic apparatus 1 may not include the acceleration sensor 150. In this case, the electronic device 1 may be connected to an acceleration sensor separate from the electronic device 1 wirelessly or by wire.
　また電子機器１は、加速度センサ１５０以外のセンサを備えてもよい。例えば、電子機器１は、気圧センサ、地磁気センサ、温度センサ、近接センサ、照度センサ及びジャイロセンサの少なくとも一つを備えてもよい。また電子機器１は、それとは別体の、加速度センサ１５０以外のセンサと、無線あるいは有線で接続されてもよい。 Also, the electronic device 1 may include a sensor other than the acceleration sensor 150. For example, the electronic device 1 may include at least one of an atmospheric pressure sensor, a geomagnetic sensor, a temperature sensor, a proximity sensor, an illuminance sensor, and a gyro sensor. In addition, the electronic device 1 may be connected to a sensor other than the acceleration sensor 150 other than the acceleration sensor 150 in a wireless or wired manner.
　＜画像位置制御について＞
　制御部１００は、電子機器１の移動に基づいて、所定のフレームレートで表示部１２０に表示される画像の表示位置を制御することによって、当該画像についての地球に対する位置を制御する画像位置制御を行うことが可能である。言い換えれば、制御部１００は、電子機器１の機器ケース１１の移動に基づいて、所定のフレームレートで表示部１２０に表示される画像の表示位置を制御することによって、当該画像についての地球に対する位置を制御する画像位置制御を行うことが可能である。画像の表示位置は、表示画面１２１内での画像の位置であるとも言える。所定のフレームレートで表示部１２０に表示される画像は、動画であってもよいし、静止画であってもよい。所定のフレームレートは、例えば６０ｆｐｓである。なお、所定のフレームレートは、これ以外であってもよい。 <About image position control>
The control unit 100 performs image position control for controlling the position of the image with respect to the earth by controlling the display position of the image displayed on the display unit 120 at a predetermined frame rate based on the movement of the electronic device 1. Is possible. In other words, the control unit 100 controls the display position of the image displayed on the display unit 120 at a predetermined frame rate based on the movement of the device case 11 of the electronic device 1, thereby positioning the image with respect to the earth. It is possible to perform image position control for controlling the. It can be said that the image display position is the position of the image in the display screen 121. The image displayed on the display unit 120 at a predetermined frame rate may be a moving image or a still image. The predetermined frame rate is, for example, 60 fps. The predetermined frame rate may be other than this.
　図５は画像位置制御の一例の概要を説明するための図である。図５は、あるフレーム期間Ｔ１から次のフレーム期間Ｔ２までに、電子機器１が＋Ｘ軸方向に移動量Ｌだけ移動する様子を示している。フレーム期間とは、１枚のフレーム画像が表示される期間である。例えば、フレームレートが６０ｆｐｓであるとすると、フレーム期間の長さは６０分の１秒となる。図５の上側には、フレーム期間Ｔ１での電子機器１が示され、図５の下側には、フレーム期間Ｔ２での電子機器１が示されている。図５の例では、電子機器１の表示画面１２１には、例えば、「ＡＢＣ」という文字列４０１を含む画像（静止画）４００が表示されている。図５では、フレーム期間Ｔ１に表示される画像４００の中心位置５０１と、フレーム期間Ｔ２に表示される画像４００の中心位置５０２とがバツ印で示されている。表示部１２０は、ホールド型表示を行うことから、１フレーム期間では、表示部１２０に表示される画像４００が変化しないと言える。つまり、画像４００の表示位置は、１フレーム期間において変化しないと言える。 FIG. 5 is a diagram for explaining an outline of an example of image position control. FIG. 5 shows a state in which the electronic device 1 moves by a movement amount L in the + X axis direction from a certain frame period T1 to the next frame period T2. The frame period is a period during which one frame image is displayed. For example, if the frame rate is 60 fps, the length of the frame period is 1/60 second. The upper side of FIG. 5 shows the electronic device 1 in the frame period T1, and the lower side of FIG. 5 shows the electronic device 1 in the frame period T2. In the example of FIG. 5, for example, an image (still image) 400 including a character string 401 “ABC” is displayed on the display screen 121 of the electronic device 1. In FIG. 5, the center position 501 of the image 400 displayed in the frame period T1 and the center position 502 of the image 400 displayed in the frame period T2 are indicated by crosses. Since the display unit 120 performs hold-type display, it can be said that the image 400 displayed on the display unit 120 does not change in one frame period. That is, it can be said that the display position of the image 400 does not change in one frame period.
　図５の例では、画像４００の大きさは、表示画面１２１の大きさと一致している。フレーム期間Ｔ１では、表示画面１２１の中心位置と画像４００の中心位置５０１とが一致するように、画像４００が表示画面１２１に表示されている。 In the example of FIG. 5, the size of the image 400 matches the size of the display screen 121. In the frame period T1, the image 400 is displayed on the display screen 121 so that the center position of the display screen 121 matches the center position 501 of the image 400.
　図５に示されるように、フレーム期間Ｔ１から次のフレーム期間Ｔ２までに、電子機器１が地球に対して＋Ｘ軸方向に沿って移動量Ｌだけ移動すると、制御部１００による画像位置制御によって、次のフレーム期間Ｔ２では、表示画面１２１での画像４００の表示位置が、フレーム期間Ｔ１での表示位置よりも－Ｘ軸方向に沿って移動量Ｌだけ移動する。したがって、図５の下側に示されるように、フレーム期間Ｔ２での画像４００の中心位置５０２は、フレーム期間Ｔ１での画像４００の中心位置５０１よりも－Ｘ軸方向に沿って移動量Ｌだけずれている。 As shown in FIG. 5, when the electronic apparatus 1 moves by the movement amount L along the + X axis direction with respect to the earth from the frame period T1 to the next frame period T2, the image position control by the control unit 100 causes In the next frame period T2, the display position of the image 400 on the display screen 121 moves by a movement amount L along the −X axis direction from the display position in the frame period T1. Therefore, as shown in the lower side of FIG. 5, the center position 502 of the image 400 in the frame period T2 is equal to the center position 501 of the image 400 in the frame period T1 by the movement amount L along the −X axis direction. It's off.
　このように、表示画面１２１での画像の表示位置を、電子機器１の移動方向とは逆方向に、電子機器１の移動量だけ移動させることによって、地球に対する画像の位置を動きにくくすることができる。言い換えれば、空間に対する画像の相対的な位置を動きにくくすることができる。これにより、表示部１２０に表示される画像の視認性が向上する。 As described above, by moving the display position of the image on the display screen 121 in the direction opposite to the moving direction of the electronic device 1 by the moving amount of the electronic device 1, the position of the image with respect to the earth can be made difficult to move. it can. In other words, the relative position of the image with respect to the space can be made difficult to move. Thereby, the visibility of the image displayed on the display unit 120 is improved.
　例えば、電子機器１を手に持つユーザがバス等の車両内に存在する場合には、ユーザの手が揺れて、電子機器１の地球に対する位置が動くことがある。本例では、電子機器１を手に持つユーザが車両内に存在する場合であっても、電子機器１が表示する画像については、地球に対する位置（相対的な位置）が動きにくくなる。そのため、ユーザは、電子機器１に表示される画像を視認しやすくなる。また、電子機器１に表示される画像に含まれる、文字、記号及び図形等の対象物（図５では文字列４０１）についての地球に対する位置も動きにくくなることから、当該対象物の視認性が向上する。 For example, when a user holding the electronic device 1 is present in a vehicle such as a bus, the user's hand may be shaken to move the position of the electronic device 1 with respect to the earth. In this example, even when a user who holds the electronic device 1 is present in the vehicle, the position (relative position) of the image displayed by the electronic device 1 is less likely to move. Therefore, the user can easily view the image displayed on the electronic device 1. Further, since the position of the target object (character string 401 in FIG. 5) included in the image displayed on the electronic device 1 with respect to the earth is difficult to move, the visibility of the target object is increased. improves.
　また本例では、電子機器１を持つユーザの手が、加齢あるいは病気などの事情により震える場合であっても、電子機器１が表示する画像についての地球に対する位置が動きにくくなる。よって、ユーザは、電子機器１に表示される画像を視認しやすくなる。 Also, in this example, even if the user's hand holding the electronic device 1 shakes due to aging or illness, the position of the image displayed by the electronic device 1 with respect to the earth becomes difficult to move. Therefore, the user can easily view the image displayed on the electronic device 1.
　また、電子機器１に表示される画像の視認性が悪い場合には、ユーザは気分が悪くなる可能性があるが、本例の電子機器１によれば、このようなことが発生する可能性が低減する。 In addition, when the visibility of the image displayed on the electronic device 1 is poor, the user may feel unwell. However, according to the electronic device 1 of the present example, such a possibility may occur. Is reduced.
　なお本例のように、表示画面１２１の大きさと画像４００の大きさが同じであって、画像位置制御によって画像４００全体の表示位置が移動する場合には、図５の下側に示されるように、表示画面１２１には画像４００の一部だけが表示されて、表示画面１２１に画像４００が表示されない領域１２１ａが発生する。この場合には、領域１２１ａに画像４００とは異なる所定の画像が表示されてもよい。例えば、領域１２１ａには、各画素の色が所定の色（例えば黒色）である画像が表示されてもよい。また、画像４００の大きさは表示画面１２１の大きさよりも小さくてもよい。 As in this example, when the display screen 121 and the image 400 have the same size and the display position of the entire image 400 is moved by the image position control, as shown in the lower side of FIG. Further, only a part of the image 400 is displayed on the display screen 121, and an area 121 a where the image 400 is not displayed on the display screen 121 is generated. In this case, a predetermined image different from the image 400 may be displayed in the area 121a. For example, an image in which the color of each pixel is a predetermined color (for example, black) may be displayed in the region 121a. Further, the size of the image 400 may be smaller than the size of the display screen 121.
　次に画像位置制御について詳細に説明する。本例では、制御部１００は、後述するように、少なくとも一つの条件に基づいて、画像位置制御を行うか否かを決定する。したがって、本例では、画像位置制御は、常に実行されるのではなく、その実行が決定されたときにだけ実行される。 Next, image position control will be described in detail. In this example, the control unit 100 determines whether to perform image position control based on at least one condition, as will be described later. Therefore, in this example, the image position control is not always executed, but only when the execution is determined.
　以後、電子機器１の説明において注目するフレーム期間を「対象フレーム期間」と呼ぶことがある。また、対象フレーム期間に表示すべき画像を「対象画像」と呼ぶことがある。また、画像位置制御が実行されないときの画像の表示位置を「標準表示位置」と呼ぶことがある。標準表示位置としては、例えば、図５の上側の電子機器１での画像４００の表示位置のように、表示画面１２１の中心位置と画像の中心位置とが一致するような画像の表示位置が採用される。 Hereinafter, the frame period of interest in the description of the electronic device 1 may be referred to as the “target frame period”. An image to be displayed in the target frame period may be referred to as a “target image”. In addition, an image display position when image position control is not executed may be referred to as a “standard display position”. As the standard display position, for example, an image display position in which the center position of the display screen 121 matches the center position of the image, such as the display position of the image 400 in the upper electronic device 1 in FIG. Is done.
　図６は、電子機器１が対象フレーム期間に画像を表示する際の当該電子機器１の動作の一例を示すフローチャートである。電子機器１は、各フレーム期間について図６に示される処理を実行する。 FIG. 6 is a flowchart showing an example of the operation of the electronic device 1 when the electronic device 1 displays an image during the target frame period. The electronic device 1 executes the process shown in FIG. 6 for each frame period.
　図６に示されるように、ステップｓ１において、制御部１００は、記憶部１０３に記憶されている実行フラグがオンであるか否かを確認する。ステップｓ１は、例えばＣＰＵ１０１によって実行される。実行フラグは、画像位置制御を行うか否かを示すフラグである。実行フラグがオンのときには画像位置制御が行われ、実行フラグがオフのときには画像位置制御が行われない。実行フラグの設定については後で詳細に説明する。 As shown in FIG. 6, in step s1, the control unit 100 confirms whether or not the execution flag stored in the storage unit 103 is on. Step s1 is executed by the CPU 101, for example. The execution flag is a flag indicating whether or not to perform image position control. Image position control is performed when the execution flag is on, and image position control is not performed when the execution flag is off. The setting of the execution flag will be described in detail later.
　ステップｓ１において、制御部１００は、実行フラグがオフであることを確認すると、ステップｓ２において、表示部１２０に、対象画像を標準表示位置に表示させる。ステップｓ２では、ＣＰＵ１０１が、表示パネル１２２を駆動する駆動回路３００を制御することによって、対象画像が標準表示位置に表示される。 In step s1, when confirming that the execution flag is off, the control unit 100 causes the display unit 120 to display the target image at the standard display position in step s2. In step s2, the CPU 101 controls the drive circuit 300 that drives the display panel 122, so that the target image is displayed at the standard display position.
　一方で、ステップｓ１において、制御部１００は、実行フラグがオンであることを確認すると、ステップｓ３，ｓ４を実行して画像位置制御を行う。ステップｓ３では、制御部１００は、加速度センサ１５０の出力信号に基づいて、電子機器１の移動を特定する。具体的には、制御部１００は、加速度センサ１５０の出力信号に基づいて、電子機器１についての所定期間でのＸＹ平面内の移動量及び移動方向を特定する。言い換えれば、制御部１００は、加速度センサ１５０の出力信号に基づいて、所定期間における、表示画面１２１に平行な面での電子機器１の移動量及び移動方向を特定する。この所定期間を「観測期間」と呼ぶことがある。観測期間は、例えば、対象フレーム期間よりも一つ前のフレーム期間の開始から、対象フレーム期間の開始よりも少し前までの期間が採用される。したがって、制御部１００は、概ね、対象フレーム期間よりも一つ前のフレーム期間での電子機器１のＸＹ平面内の移動量及び移動方向を特定すると言える。ステップｓ３は例えばＣＰＵ１０１で実行される。 On the other hand, in step s1, when confirming that the execution flag is on, the control unit 100 executes steps s3 and s4 to perform image position control. In step s3, the control unit 100 identifies the movement of the electronic device 1 based on the output signal of the acceleration sensor 150. Specifically, based on the output signal of acceleration sensor 150, control unit 100 specifies the movement amount and movement direction in the XY plane for electronic device 1 over a predetermined period. In other words, the control unit 100 specifies the movement amount and movement direction of the electronic device 1 on a plane parallel to the display screen 121 in a predetermined period based on the output signal of the acceleration sensor 150. This predetermined period may be referred to as an “observation period”. As the observation period, for example, a period from the start of a frame period immediately before the target frame period to a time slightly before the start of the target frame period is employed. Therefore, it can be said that the control unit 100 generally specifies the movement amount and movement direction of the electronic device 1 in the XY plane in the frame period immediately before the target frame period. Step s3 is executed by the CPU 101, for example.
　ここで、ユーザの手が加齢あるいは病気などの事情により震える場合の周波数は１０Ｈｚ以下が多い。また、車両に乗るユーザが当該車両から受ける振動の周波数は１０Ｈ以下が多い。 Here, the frequency when the user's hand shakes due to aging or illness is often 10 Hz or less. Moreover, the frequency of the vibration which the user who rides on a vehicle receives from the said vehicle has many 10H or less.
　そこで、本例では、電子機器１の移動として、例えば１０Ｈｚ以下の振動を想定する。したがって、１フレーム期間（６０分の１秒）での電子機器１の移動方向はほぼ一定であると考えることができる。以後、対象フレーム期間よりも一つ前のフレーム期間を「前フレーム期間」と呼ぶことがある。また、ステップｓ１で特定される移動量及び移動方向を「観測移動量」及び「観測移動方向」とそれぞれ呼ぶことがある。 Therefore, in this example, as the movement of the electronic device 1, for example, vibration of 10 Hz or less is assumed. Therefore, it can be considered that the moving direction of the electronic device 1 in one frame period (1/60 second) is substantially constant. Hereinafter, a frame period immediately before the target frame period may be referred to as a “previous frame period”. Further, the movement amount and movement direction specified in step s1 may be referred to as “observation movement amount” and “observation movement direction”, respectively.
　ステップｓ３が実行されると、ステップｓ４において、制御部１００は、表示部１２０に、ステップｓ３で特定された電子機器１の移動に基づいた表示位置に対象画像を表示させる。具体的には、制御部１００は、表示画面１２１での対象画像の表示位置が、前フレーム期間で表示される画像の表示位置よりも観測移動量だけ、観測移動方向とは逆方向に移動するように、対象画像を表示部１２０に表示させる。これにより、対象フレーム期間で表示される画像についての地球に対する位置は、前フレーム期間から変化しにくくなる。 When step s3 is executed, in step s4, the control unit 100 causes the display unit 120 to display the target image at the display position based on the movement of the electronic device 1 specified in step s3. Specifically, the control unit 100 moves the display position of the target image on the display screen 121 in the direction opposite to the observation movement direction by the observation movement amount from the display position of the image displayed in the previous frame period. As described above, the target image is displayed on the display unit 120. Thereby, the position of the image displayed in the target frame period with respect to the earth is less likely to change from the previous frame period.
　ステップｓ４では、例えば、ＣＰＵ１０１が、対象画像を示す画像データを元にして、観測移動量及び観測移動方向に基づいて、対象画像のうち、表示画面１２１に実際に表示される部分を示す画像データを生成する。そして、駆動回路３００が、ＣＰＵ１０１で生成された画像データに基づいて表示パネル１２２を駆動することによって、対象フレーム期間での対象画像の表示位置が、前フレーム期間で表示される画像の表示位置よりも観測移動量だけ、観測移動方向とは逆方向に移動するように、対象画像が表示画面１２１に表示される。 In step s4, for example, the CPU 101, based on the image data indicating the target image, based on the observation movement amount and the observation movement direction, image data indicating a portion of the target image that is actually displayed on the display screen 121. Is generated. The drive circuit 300 drives the display panel 122 based on the image data generated by the CPU 101, so that the display position of the target image in the target frame period is greater than the display position of the image displayed in the previous frame period. The target image is displayed on the display screen 121 so as to move in the direction opposite to the observation movement direction by the observation movement amount.
　またステップｓ４では、例えば、ＣＰＵ１０１は、対象画像を示す画像データと、取得した観測移動量及び観測移動方向とを駆動回路３００に出力してもよい。この場合、駆動回路３００は、対象フレーム期間での対象画像の表示位置が、前フレーム期間で表示される画像の表示位置よりも観測移動量だけ、観測移動方向とは逆方向に移動するように、ＣＰＵ１０１から受け取った画像データ、観測移動量及び観測移動方向に基づいて、表示パネル１２２を駆動する。 In step s4, for example, the CPU 101 may output the image data indicating the target image and the acquired observation movement amount and observation movement direction to the drive circuit 300. In this case, the drive circuit 300 causes the display position of the target image in the target frame period to move in the direction opposite to the observation movement direction by the observation movement amount from the display position of the image displayed in the previous frame period. The display panel 122 is driven based on the image data, the observation movement amount, and the observation movement direction received from the CPU 101.
　なお、電子機器１の移動がＺ軸方向だけに沿った移動である場合などでは、ステップｓ３での観測移動量は零となる。したがって、この場合には、対象フレーム期間での画像の表示位置は前フレーム期間から変化しない。 In addition, when the movement of the electronic device 1 is a movement along only the Z-axis direction, the observation movement amount in step s3 is zero. Therefore, in this case, the image display position in the target frame period does not change from the previous frame period.
　以上のステップｓ１～ｓ４の処理を、制御部１００が、各フレーム期間を対象フレーム期間として実行することによって、所定のフレームレートで表示画面１２１に表示される画像についての地球に対する位置は動きにくくなる。本例では、画像位置制御の実行中での画像の地球に対する位置が、当該画像が標準表示位置に表示される場合の当該画像の地球に対する位置から変化しにくくなる。その結果、画像の視認性が向上する。以後、画像が標準表示位置に表示される場合の当該画像の地球に対する位置を「地球に対する画像の標準位置」と呼ぶことがある。 When the control unit 100 executes the processing of steps s1 to s4 as each frame period as the target frame period, the position of the image displayed on the display screen 121 at a predetermined frame rate becomes difficult to move. . In this example, the position of the image with respect to the earth during execution of the image position control is less likely to change from the position of the image with respect to the earth when the image is displayed at the standard display position. As a result, the visibility of the image is improved. Hereinafter, when the image is displayed at the standard display position, the position of the image with respect to the earth may be referred to as “standard position of the image with respect to the earth”.
　図７は、画像位置制御の実行中において、地球に対する画像の位置が制御されている様子の一例を示す図である。図７には、電子機器１が複数のフレーム期間において＋Ｘ軸方向に移動する場合の例が示されている。図７では、＋Ｘ軸方向における、地球に対する画像の位置を縦軸が示しており、横軸が時間を示している。グラフ６００は、画像位置制御を実行している電子機器１が複数のフレーム期間において＋Ｘ軸方向に移動する場合における、地球に対する画像の位置の時間変化を示している。グラフ６１０は、画像位置制御を実行していない電子機器１が複数のフレーム期間において＋Ｘ軸方向に移動する場合における、地球に対する画像の位置の時間変化を示している。 FIG. 7 is a diagram illustrating an example of a state in which the position of the image with respect to the earth is controlled during the execution of the image position control. FIG. 7 shows an example in which the electronic apparatus 1 moves in the + X axis direction in a plurality of frame periods. In FIG. 7, the vertical axis indicates the position of the image with respect to the earth in the + X axis direction, and the horizontal axis indicates time. A graph 600 shows a temporal change in the position of the image with respect to the earth when the electronic device 1 that is performing image position control moves in the + X-axis direction in a plurality of frame periods. A graph 610 shows a temporal change in the position of the image with respect to the earth when the electronic device 1 that is not executing the image position control moves in the + X-axis direction in a plurality of frame periods.
　グラフ６１０に示されるように、画像位置制御が実行されない場合には、表示部１２０に表示される画像の地球に対する位置は、常に電子機器１の移動に応じて変化し、標準位置ＳＰから大きくずれることになる。 As shown in the graph 610, when the image position control is not executed, the position of the image displayed on the display unit 120 with respect to the earth always changes according to the movement of the electronic device 1 and greatly deviates from the standard position SP. It will be.
　これに対して、画像位置制御の実行中では、グラフ６００に示されるように、表示部１２０に表示される画像の地球に対する位置は、１フレーム期間内においては電子機器１の移動に応じて変化するものの、次のフレーム期間になると、地球に対する画像の標準位置ＳＰと一致するようになる。よって、表示部１２０に表示される画像の地球に対する位置は、地球に対する画像の標準位置ＳＰから変化しにくくなる。 On the other hand, during the execution of the image position control, as shown in the graph 600, the position of the image displayed on the display unit 120 with respect to the earth changes according to the movement of the electronic device 1 within one frame period. However, in the next frame period, the image coincides with the standard position SP of the image with respect to the earth. Therefore, the position of the image displayed on the display unit 120 with respect to the earth is unlikely to change from the standard position SP of the image with respect to the earth.
　なお制御部１００は、上述のステップｓ４の後に、対象画像の表示位置が標準表示位置に少し近づくように対象画像を表示部１２０に表示させてもよい。これにより、対象画像の表示位置が標準表示位置から大きく離れる可能性を低減することができる。 Note that the control unit 100 may cause the display unit 120 to display the target image so that the display position of the target image is slightly closer to the standard display position after step s4 described above. Thereby, it is possible to reduce the possibility that the display position of the target image is greatly separated from the standard display position.
　＜決定処理について＞
　本例では、制御部１００は、少なくとも一つの条件に基づいて、画像位置制御を行うか否かを決定する決定処理を行う。決定処理は例えばＣＰＵ１０１で行われる。決定処理において、画像位置制御を行うことが決定されると、実行フラグがオンに設定される。一方で、決定処理において、画像位置制御を行わないことが決定されると、実行フラグがオフに設定される。 <About decision processing>
In this example, the control unit 100 performs a determination process that determines whether to perform image position control based on at least one condition. The determination process is performed by the CPU 101, for example. If it is determined in the determination process that image position control is to be performed, the execution flag is set to ON. On the other hand, if it is determined in the determination process that image position control is not performed, the execution flag is set to OFF.
　制御部１００は、決定処理において、例えば、表示画面１２１の向きが安定しているか否かという第１条件に基づいて、画像位置制御を行うか否かを決定する。 In the determination process, the control unit 100 determines whether or not to perform the image position control based on, for example, a first condition as to whether or not the orientation of the display screen 121 is stable.
　制御部１００は、表示画面１２１の向きが安定していると判定する場合には画像位置制御を行うことを決定して、実行フラグをオンにする。一方で、制御部１００は、表示画面１２１の向きが安定していないと判定する場合には画像位置制御を行わないことを決定して、実行フラグをオフにする。 When the controller 100 determines that the orientation of the display screen 121 is stable, the controller 100 determines to perform image position control and turns on the execution flag. On the other hand, when determining that the orientation of the display screen 121 is not stable, the control unit 100 determines not to perform image position control and turns off the execution flag.
　ここで、ユーザが表示画面１２１を見ている場合には、当該表示画面１２１の向きが安定している可能性が高い。電子機器１を手に持つユーザが車両に乗っている場合であっても、電子機器１は振動することがあるものの、ユーザが表示画面１２１を見ているときの当該表示画面１２１の向きは安定している可能性が高い。 Here, when the user is looking at the display screen 121, there is a high possibility that the orientation of the display screen 121 is stable. Even when a user holding the electronic device 1 is in the vehicle, the electronic device 1 may vibrate, but the orientation of the display screen 121 when the user is viewing the display screen 121 is stable. It is highly possible that
　本例のように、制御部１００が、表示画面１２１の向きが安定しているか否かという第１条件に基づいて、画像位置制御を行うか否かを決定することによって、電子機器１は、ユーザが表示画面１２１を見ている可能性が高いときに画像位置制御を行い、ユーザが表示画面１２１を見ている可能性が低いときに画像位置制御を行わないことが可能となる。よって、電子機器１は、必要性が高いときに画像位置制御を実行し、必要性が低いときに画像位置制御を行わないことが可能となる。その結果、画像位置制御の実効性が向上するとともに、電子機器１の消費電力が低減する。 As in this example, the control unit 100 determines whether or not to perform image position control based on the first condition whether or not the orientation of the display screen 121 is stable. It is possible to perform image position control when the possibility that the user is looking at the display screen 121 is high, and not to perform image position control when the possibility that the user is looking at the display screen 121 is low. Therefore, the electronic device 1 can perform image position control when necessity is high, and can not perform image position control when necessity is low. As a result, the effectiveness of the image position control is improved and the power consumption of the electronic device 1 is reduced.
　図８は決定処理の一例を示すフローチャートである。制御部１００は、図８に示される決定処理を繰り返し実行する。 FIG. 8 is a flowchart showing an example of the determination process. The control unit 100 repeatedly executes the determination process shown in FIG.
　図８に示されるように、ステップｓ１１において、制御部１００は、加速度センサ１５０の出力信号に基づいて、表示画面の向きが安定しているか否かを判定する第１判定を行う。第１判定では、制御部１００は、加速度センサ１５０の出力信号に基づいて、所定期間の間に、表示画面１２１の向きを複数回特定する。例えば、制御部１００は、数十フレーム期間の間に、数フレーム期間ごとに表示画面１２１の向きを特定する。制御部１００は、加速度センサ１５０の出力信号に基づいて、表示画面１２１に垂直な方向であって、当該表示画面１２１から電子機器１の外側に向かう方向を特定し、特定した方向を表示画面１２１の向きとする。次に制御部１００は、複数回特定した表示画面１２１の向きの平均を求めて、それを基準方向とする。次に制御部１００は、複数回特定した表示画面１２１の向きのそれぞれと、基準方向との間の角度を求める。そして、制御部１００は、求めた複数の角度のすべてがしきい値以下である場合、表示画面１２１の向きが安定していると判定する。これより、第１判定の結果がＹＥＳとなる。一方で、制御部１００は、求めた複数の角度の少なくとも一つがしきい値よりも大きい場合、表示画面１２１の向きが安定していないと判定する。これより、第１判定の結果がＮＯとなる。しきい値は、例えば１０～２０度に設定される。 As shown in FIG. 8, in step s11, the control unit 100 performs a first determination based on the output signal of the acceleration sensor 150 to determine whether the orientation of the display screen is stable. In the first determination, the control unit 100 specifies the orientation of the display screen 121 a plurality of times during a predetermined period based on the output signal of the acceleration sensor 150. For example, the control unit 100 specifies the orientation of the display screen 121 every several frame periods during several tens of frame periods. Based on the output signal of the acceleration sensor 150, the control unit 100 identifies a direction perpendicular to the display screen 121 and going from the display screen 121 toward the outside of the electronic device 1, and the identified direction is displayed on the display screen 121. And the direction. Next, the control unit 100 obtains the average of the orientations of the display screen 121 specified a plurality of times, and sets this as the reference direction. Next, the control unit 100 obtains an angle between each of the orientations of the display screen 121 specified a plurality of times and the reference direction. And the control part 100 determines with the direction of the display screen 121 being stable, when all the calculated | required some angles are below a threshold value. As a result, the result of the first determination is YES. On the other hand, the control unit 100 determines that the orientation of the display screen 121 is not stable when at least one of the obtained plurality of angles is larger than the threshold value. As a result, the result of the first determination is NO. The threshold value is set to 10 to 20 degrees, for example.
　なお、制御部１００は、電子機器１の周囲の地磁気を検出する地磁気センサの出力信号に基づいて、表示画面１２１の向きを特定してもよい。また、制御部１００は、電子機器１の角速度を検出するジャイロセンサの出力信号に基づいて、表示画面１２１の向きを特定してもよい。また、制御部１００は、加速度センサ１５０、地磁気センサ及びジャイロセンサの少なくとも２つの出力信号に基づいて、表示画面１２１の向きを特定してもよい。 The control unit 100 may specify the orientation of the display screen 121 based on the output signal of the geomagnetic sensor that detects the geomagnetism around the electronic device 1. Further, the control unit 100 may specify the orientation of the display screen 121 based on the output signal of the gyro sensor that detects the angular velocity of the electronic device 1. The control unit 100 may specify the orientation of the display screen 121 based on at least two output signals of the acceleration sensor 150, the geomagnetic sensor, and the gyro sensor.
　ステップｓ１１において、表示画面１２１の向きが安定していると判定されると（ＹＥＳ）、ステップｓ１２において、制御部１００は、画像位置制御を行うことを決定する。そして、ステップｓ１３において、制御部１００は、実行フラグをオンに設定する。 If it is determined in step s11 that the orientation of the display screen 121 is stable (YES), in step s12, the control unit 100 determines to perform image position control. In step s13, the control unit 100 sets the execution flag to ON.
　一方で、ステップｓ１１において、表示画面１２１の向きが安定していないと判定されると（ＮＯ）、ステップｓ１４において、制御部１００は、画像位置制御を行わないことを決定する。そして、ステップｓ１５において、制御部１００は、実行フラグをオフに設定する。 On the other hand, if it is determined in step s11 that the orientation of the display screen 121 is not stable (NO), in step s14, the control unit 100 determines not to perform image position control. In step s15, the control unit 100 sets the execution flag to OFF.
　なお、決定処理では、複数の条件が使用されてもよい。つまり、制御部１００は、決定処理において、複数の条件に基づいて、画像位置制御を行うか否かを決定してもよい。 In the determination process, a plurality of conditions may be used. That is, the control unit 100 may determine whether to perform image position control based on a plurality of conditions in the determination process.
　例えば、決定処理では、第１条件と、電子機器１が移動しているか否かという第２条件とが使用されてもよい。図９はこの場合の決定処理の一例を示すフローチャートである。図９に示される決定処理では、まずステップｓ２１において、制御部１００は、加速度センサ１５０の出力信号に基づいて、電子機器１が移動しているか否かを判定する第２判定を行う。第２判定において、電子機器１が移動していないと判定されると、上述のステップｓ１４が実行される。以後、制御部１００は同様に動作する。一方で、第２判定において、電子機器１が移動していると判定されると、上述のステップｓ１１が実行される。以後、制御部１００は同様に動作する。 For example, in the determination process, a first condition and a second condition indicating whether or not the electronic device 1 is moving may be used. FIG. 9 is a flowchart showing an example of the determination process in this case. In the determination process shown in FIG. 9, first, in step s <b> 21, the control unit 100 performs a second determination that determines whether or not the electronic device 1 is moving based on the output signal of the acceleration sensor 150. If it is determined in the second determination that the electronic device 1 is not moving, the above-described step s14 is executed. Thereafter, the control unit 100 operates in the same manner. On the other hand, when it is determined in the second determination that the electronic device 1 is moving, the above-described step s11 is executed. Thereafter, the control unit 100 operates in the same manner.
　このように、制御部１００が、電子機器１が移動しているか否かという第２条件に基づいて、画像位置制御を行うか否かを決定することによって、電子機器１は、必要性が高いときに画像位置制御を実行し、必要が低いときに画像位置制御を実行しないことが可能となる。これにより、画像位置制御の実効性が向上するとともに、電子機器１の消費電力が低減する。 In this way, the electronic device 1 is highly necessary because the control unit 100 determines whether or not to perform image position control based on the second condition whether or not the electronic device 1 is moving. Sometimes it is possible to perform image position control and not perform image position control when the need is low. Thereby, the effectiveness of the image position control is improved and the power consumption of the electronic device 1 is reduced.
　また決定処理では、第１条件と、第２条件と、電子機器１の動作モードが、画像位置制御を行う制御モードに設定されているか否かという第３条件とが使用されてもよい。図１０はこの場合の決定処理の一例を示すフローチャートである。 In the determination process, a first condition, a second condition, and a third condition indicating whether or not the operation mode of the electronic device 1 is set to a control mode for performing image position control may be used. FIG. 10 is a flowchart showing an example of the determination process in this case.
　図１０に示される決定処理を行う電子機器１の動作モードには、画像位置制御を行う制御モードと、画像位置制御を行わない通常モードとが含まれる。ユーザは、例えば、電子機器１の表示画面１２１を操作することによって、電子機器１の動作モードを当該電子機器１に設定することができる。通常モードの電子機器１は画像を標準表示位置に表示する。 The operation modes of the electronic device 1 that performs the determination process shown in FIG. 10 include a control mode that performs image position control and a normal mode that does not perform image position control. For example, the user can set the operation mode of the electronic device 1 to the electronic device 1 by operating the display screen 121 of the electronic device 1. The electronic device 1 in the normal mode displays an image at the standard display position.
　図１０に示される決定処理では、まずステップｓ３１において、制御部１００は、電子機器１の動作モードが制御モードに設定されているか否かを判定する第３判定を行う。第３判定において、電子機器１の動作モードが制御モードに設定されていないと判定されると、つまり、電子機器１の動作モードが通常モードである場合、制御部１００は上述のステップｓ１４を実行する。以後、制御部１００は同様に動作する。一方で、第３判定において、電子機器１の動作モードが制御モードに設定されていると判定されると、制御部１００は上述のステップｓ２１を実行する。以後、制御部１００は図９と同様に動作する。 In the determination process shown in FIG. 10, first, in step s31, the control unit 100 performs a third determination for determining whether or not the operation mode of the electronic device 1 is set to the control mode. In the third determination, when it is determined that the operation mode of the electronic device 1 is not set to the control mode, that is, when the operation mode of the electronic device 1 is the normal mode, the control unit 100 executes step s14 described above. To do. Thereafter, the control unit 100 operates in the same manner. On the other hand, in the third determination, when it is determined that the operation mode of the electronic device 1 is set to the control mode, the control unit 100 executes step s21 described above. Thereafter, the control unit 100 operates in the same manner as in FIG.
　このように、制御部１００が、電子機器１の動作モードが制御モードに設定されているか否かという第３条件に基づいて、画像位置制御を行うか否かを決定することによって、ユーザが画像位置制御の実行を望まないときに画像位置制御が実行される可能性を低減することができる。よって、電子機器１の利便性が向上するとともに、電子機器１の消費電力が低減する。 As described above, the control unit 100 determines whether or not to perform image position control based on the third condition as to whether or not the operation mode of the electronic device 1 is set to the control mode. The possibility that the image position control is executed when it is not desired to execute the position control can be reduced. Therefore, the convenience of the electronic device 1 is improved and the power consumption of the electronic device 1 is reduced.
　なお、図９の決定処理において、ステップｓ１１が実行されなくてもよい。また図１０の決定処理において、ステップｓ１１，ｓ２１の少なくとも一方が実行されなくてもよい。 Note that step s11 may not be executed in the determination process of FIG. In the determination process of FIG. 10, at least one of steps s11 and s21 may not be executed.
　以上のように、電子機器１が、少なくとも一つの条件に基づいて、画像位置制御を行うか否かを決定することによって、画像位置制御の実効性を向上させつつ、電子機器１の消費電力を低減することができる。 As described above, the electronic device 1 determines whether or not to perform image position control based on at least one condition, thereby improving the effectiveness of the image position control and reducing the power consumption of the electronic device 1. Can be reduced.
　＜他の実施例＞
　以下に電子機器１の他の実施例について説明する。 <Other embodiments>
Other embodiments of the electronic device 1 will be described below.
　＜第１実施例＞
　電子機器１が微細な振動を行っている場合には、表示画面１２１が表示する画像の残像がユーザにとって見える可能性が高い。その結果、表示画面１２１を見るユーザが気分を悪くする可能性がある。また、表示画面１２１が表示する画像の残像がユーザにとって見える可能性が低いときに、画像位置制御が行われると、ユーザは違和感を受ける可能性がある。 <First embodiment>
When the electronic device 1 is performing minute vibration, there is a high possibility that the afterimage of the image displayed on the display screen 121 is visible to the user. As a result, the user who views the display screen 121 may feel unwell. Further, when the image position control is performed when the afterimage of the image displayed on the display screen 121 is unlikely to be visible to the user, the user may feel uncomfortable.
　そこで、本実施例に係る決定処理では、電子機器１において微細な振動が一定時間継続しているか否かという第４条件が使用される。 Therefore, in the determination process according to the present embodiment, a fourth condition is used, in which whether or not minute vibrations continue in the electronic device 1 for a certain period of time.
　本実施例では、上述の図８～１０に示されるステップｓ１１において、制御部１００は、第１判定を行うとともに、電子機器１において微細な振動が一定時間継続しているか否かを判定する第４判定を行う。 In the present embodiment, in step s11 shown in FIGS. 8 to 10 described above, the control unit 100 performs the first determination and determines whether or not minute vibrations in the electronic device 1 continue for a predetermined time. 4. Make a decision.
　制御部１００は、加速度センサ１５０の出力信号に基づいて、電子機器１において微細な振動が一定時間継続しているか否かを判定することができる。第４判定において、制御部１００は、まず、加速度センサ１５０の出力信号に基づいて、所定期間の間、Ｘ軸方向あるいはＹ軸方向での電子機器１の振動の振幅及び周期のそれぞれを複数回特定する。次に制御部１００は、複数回特定した振幅のそれぞれが第１しきい値以下であるか否かと、複数回特定した周波数のそれぞれが第２しきい値以下であるか否かとを判定する。第１しきい値は例えば数十ｍｍに設定され、第２しきい値は例えば１Ｈｚ～数Ｈｚに設定される。制御部１００は、複数回特定した振幅のそれぞれが第１しきい値以下であり、複数回特定した周波数のそれぞれが第２しきい値以下である場合には、電子機器１において微細な振動が一定時間継続していると判定する。これにより、第４判定の結果がＹＥＳとなる。一方で、制御部１００は、複数回特定した振幅の少なくとも一つが第１しきい値よりも大きい場合には、第４判定の結果をＮＯとする。また制御部１００は、複数回特定した周波数の少なくとも一つが第２しきい値よりも大きい場合には、第４判定の結果をＮＯとする。 The control unit 100 can determine whether or not minute vibrations continue in the electronic device 1 for a predetermined time based on the output signal of the acceleration sensor 150. In the fourth determination, the control unit 100 first determines each of the amplitude and period of vibration of the electronic device 1 in the X-axis direction or the Y-axis direction a plurality of times for a predetermined period based on the output signal of the acceleration sensor 150. Identify. Next, the control unit 100 determines whether or not each of the amplitudes specified a plurality of times is equal to or less than the first threshold value and whether or not each of the frequencies specified a plurality of times is equal to or less than the second threshold value. The first threshold value is set to several tens mm, for example, and the second threshold value is set to 1 Hz to several Hz, for example. When each of the amplitudes specified a plurality of times is equal to or less than the first threshold value and each of the frequencies specified a plurality of times is equal to or less than the second threshold value, the control unit 100 causes minute vibrations in the electronic device 1. It is determined that it has continued for a certain time. As a result, the result of the fourth determination is YES. On the other hand, when at least one of the amplitudes specified a plurality of times is larger than the first threshold value, the control unit 100 sets the result of the fourth determination to NO. In addition, the control unit 100 sets the result of the fourth determination to NO when at least one of the frequencies specified a plurality of times is greater than the second threshold value.
　制御部１００は、ステップｓ１１において、第１判定及び第４判定の少なくとも一方でＹＥＳと判定すると、ステップｓ１２を実行し、その後同様に動作する。一方で、制御部１００は、ステップｓ１１において、第１判定及び第４判定の両方でＮＯと判定すると、ステップｓ１４を実行し、その後同様に動作する。 If the control unit 100 determines YES in at least one of the first determination and the fourth determination in step s11, the control unit 100 executes step s12 and then operates in the same manner. On the other hand, if the control unit 100 determines NO in both the first determination and the fourth determination in step s11, the control unit 100 executes step s14 and then operates in the same manner.
　なお、制御部１００は、第１判定及び第４判定の両方でＹＥＳと判定するとステップｓ１２を実行し、第１判定及び第４判定の少なくとも一方でＮＯと判定するとステップｓ１４を実行してもよい。また、ステップｓ１１では第１判定が実行されなくてもよい。この場合には、第４判定でＹＥＳと判定されるとステップｓ１２が実行され、第４判定でＮＯと判定されるとステップｓ１４が実行される。 The control unit 100 may execute step s12 when determining YES in both the first determination and the fourth determination, and execute step s14 when determining NO in at least one of the first determination and the fourth determination. . In step s11, the first determination may not be executed. In this case, if the fourth determination is YES, step s12 is executed, and if the fourth determination is NO, step s14 is executed.
　このように、本実施例では、電子機器１において微細な振動が一定時間継続しているか否かという第４条件に基づいて、画像位置制御が行われるか否かが決定される。これにより、電子機器１は、必要性が高いときに画像位置制御を実行し、必要性が低いときに画像位置制御を行わないことが可能となる。その結果、画像位置制御の実効性が向上するとともに、電子機器１の消費電力が低減する。また、表示画面１２１が表示する画像の残像がユーザにとって見える可能性が低いときに画像位置制御が行われる可能性を低減することができることから、ユーザが表示画面１２１を見たときに違和感を受ける可能性を低減することができる。 As described above, in this embodiment, whether or not the image position control is performed is determined based on the fourth condition of whether or not the minute vibration continues in the electronic device 1 for a certain period of time. Thereby, the electronic device 1 can perform image position control when the necessity is high, and can not perform the image position control when the necessity is low. As a result, the effectiveness of the image position control is improved and the power consumption of the electronic device 1 is reduced. Further, since it is possible to reduce the possibility that the image position control is performed when the afterimage of the image displayed on the display screen 121 is low for the user to see, the user feels uncomfortable when viewing the display screen 121. The possibility can be reduced.
　また、第４条件を含む複数の条件に基づいて、画像位置制御が行われるか否かが決定されることにより、画像位置制御の実効性がさらに向上するとともに、電子機器１の消費電力がさらに低減する。 Further, by determining whether or not image position control is performed based on a plurality of conditions including the fourth condition, the effectiveness of the image position control is further improved, and the power consumption of the electronic device 1 is further increased. To reduce.
　＜第２実施例＞
　電子機器１を所持するユーザが車両に乗っている場合などでは、電子機器１の振動には、類似する振動パターンが周期的に現れることがある。この場合、表示画面１２１が表示する画像の残像がユーザにとって見える可能性が高い。その結果、表示画面１２１を見るユーザが気分を悪くする可能性がある。 <Second embodiment>
When the user who possesses the electronic device 1 is on a vehicle, a similar vibration pattern may appear periodically in the vibration of the electronic device 1. In this case, there is a high possibility that the afterimage of the image displayed on the display screen 121 is visible to the user. As a result, the user who views the display screen 121 may feel unwell.
　そこで、本実施例に係る決定処理では、電子機器１の振動において類似する振動パターンが周期的に現れているか否かという第５条件が使用される。 Therefore, in the determination process according to the present embodiment, a fifth condition is used as to whether or not a similar vibration pattern appears periodically in the vibration of the electronic device 1.
　本実施例では、上述の図８～１０に示されるステップｓ１１において、制御部１００は、第１判定を行うとともに、電子機器１の振動において類似する振動パターンが周期的に現れているか否かを判定する第５判定を行う。 In the present embodiment, in step s11 shown in FIGS. 8 to 10 described above, the control unit 100 performs the first determination and determines whether or not a similar vibration pattern appears periodically in the vibration of the electronic device 1. A fifth determination is made.
　制御部１００は、加速度センサ１５０の出力信号に基づいて、電子機器１の振動において類似する振動パターンが周期的に現れているか否かを判定することができる。第５判定において、制御部１００は、まず、加速度センサ１５０の出力信号に基づいて、所定期間の間、Ｘ軸方向あるいはＹ軸方向での電子機器１の振動波形を取得する。次に制御部１００は、取得した振動波形において、類似する振動パターンが周期的に現れているか否かを判定する。制御部１００は、取得した振動波形において、類似する振動パターンが周期的に現れていると判定すると、第５判定の結果をＹＥＳとする。一方で、制御部１００は、取得した振動波形において、周期的に現れる類似する振動パターンが存在しない場合には、第５判定の結果をＮＯとする。 The control unit 100 can determine whether or not a similar vibration pattern appears periodically in the vibration of the electronic device 1 based on the output signal of the acceleration sensor 150. In the fifth determination, first, the control unit 100 acquires a vibration waveform of the electronic device 1 in the X-axis direction or the Y-axis direction for a predetermined period based on the output signal of the acceleration sensor 150. Next, the control unit 100 determines whether or not a similar vibration pattern appears periodically in the acquired vibration waveform. When the control unit 100 determines that similar vibration patterns appear periodically in the acquired vibration waveform, the result of the fifth determination is YES. On the other hand, the control unit 100 sets the result of the fifth determination to NO when there is no similar vibration pattern that appears periodically in the acquired vibration waveform.
　制御部１００は、ステップｓ１１において、第１判定及び第５判定の少なくとも一方でＹＥＳと判定すると、ステップｓ１２を実行し、その後同様に動作する。一方で、制御部１００は、ステップｓ１１において、第１判定及び第５判定の両方でＮＯと判定すると、ステップｓ１４を実行し、その後同様に動作する。 If the control unit 100 determines YES in at least one of the first determination and the fifth determination in step s11, the control unit 100 executes step s12 and then operates in the same manner. On the other hand, if the control unit 100 determines NO in both the first determination and the fifth determination in step s11, the control unit 100 executes step s14 and then operates in the same manner.
　なお、制御部１００は、第１判定及び第５判定の両方でＹＥＳと判定するとステップｓ１２を実行し、第１判定及び第５判定の少なくとも一方でＮＯと判定するとステップｓ１４を実行してもよい。 The control unit 100 may execute step s12 when determining YES in both the first determination and the fifth determination, and execute step s14 when determining NO in at least one of the first determination and the fifth determination. .
　また第１実施例と同様に、ステップｓ１１では第１判定が実行されなくてもよい。またステップｓ１１では、第１判定、第４判定及び第５判定が実行されてもよい。つまり、制御部１００は、第１条件、第４条件及び第５条件に基づいて、画像位置制御を行うか否かを決定してもよい。この場合には、制御部１００は、第１判定、第４判定及び第５判定の少なくとも一つでＹＥＳと判定するとステップｓ１２を実行し、これらの判定のすべてにおいてＮＯと判定するとステップｓ１４を実行してよい。また、制御部１００は、第１判定、第４判定及び第５判定のすべてでＹＥＳと判定するとステップｓ１２を実行し、これらの判定の少なくとも一つでＮＯと判定するとステップｓ１４を実行してもよい。 As in the first embodiment, the first determination may not be executed in step s11. In Step s11, the first determination, the fourth determination, and the fifth determination may be performed. That is, the control unit 100 may determine whether to perform image position control based on the first condition, the fourth condition, and the fifth condition. In this case, when it is determined YES in at least one of the first determination, the fourth determination, and the fifth determination, the control unit 100 executes Step s12, and when it determines NO in all of these determinations, it executes Step s14. You can do it. The control unit 100 executes step s12 if it is determined YES in all of the first determination, the fourth determination, and the fifth determination, and executes step s14 if it is determined NO in at least one of these determinations. Good.
　このように、本実施例では、電子機器１の振動において類似する振動パターンが周期的に現れているか否かという第５条件に基づいて、画像位置制御が行われるか否かが決定される。これにより、第１実施例と同様に、画像位置制御の実効性が向上するとともに、電子機器１の消費電力が低減する。また、ユーザが表示画面１２１を見たときに違和感を受ける可能性を低減することができる。 Thus, in the present embodiment, whether or not the image position control is performed is determined based on the fifth condition whether or not a similar vibration pattern appears periodically in the vibration of the electronic device 1. As a result, as in the first embodiment, the effectiveness of the image position control is improved and the power consumption of the electronic device 1 is reduced. Further, it is possible to reduce the possibility that the user feels uncomfortable when viewing the display screen 121.
　また、第５条件を含む複数の条件に基づいて、画像位置制御が行われるか否かが決定されることにより、画像位置制御の実効性がさらに向上するとともに、電子機器１の消費電力がさらに低減する。 Further, by determining whether or not the image position control is performed based on a plurality of conditions including the fifth condition, the effectiveness of the image position control is further improved, and the power consumption of the electronic device 1 is further increased. Reduce.
　＜第３実施例＞
　電子機器１を所持するユーザが、自転車及び自動車等の車両に乗っている場合には、表示画面１２１が表示する画像の残像がユーザにとって見える可能性が高い。その結果、表示画面１２１を見るユーザが気分を悪くする可能性がある。 <Third embodiment>
When the user who possesses the electronic device 1 is riding a vehicle such as a bicycle or a car, there is a high possibility that the afterimage of the image displayed on the display screen 121 is visible to the user. As a result, the user who views the display screen 121 may feel unwell.
　そこで、本実施例に係る決定処理では、電子機器１のユーザが車両に乗っているか否かという第６条件が使用される。 Therefore, in the determination process according to the present embodiment, a sixth condition is used as to whether or not the user of the electronic device 1 is on the vehicle.
　本実施例では、上述の図８～１０に示されるステップｓ１１において、制御部１００は、第１判定を行うとともに、電子機器１のユーザが車両に乗っているか否かを判定する第６判定を行う。ステップｓ１１において、制御部１００は、ユーザが車両に乗っていると判定すると、第６判定の結果をＹＥＳとする。一方で、制御部１００は、ユーザが車両に乗っていないと判定すると、第６判定の結果をＮＯとする。 In the present embodiment, in step s11 shown in FIGS. 8 to 10 described above, the control unit 100 performs the first determination and the sixth determination for determining whether or not the user of the electronic device 1 is on the vehicle. Do. In step s11, when the control unit 100 determines that the user is on the vehicle, the result of the sixth determination is YES. On the other hand, if the control unit 100 determines that the user is not on the vehicle, the result of the sixth determination is NO.
　制御部１００は、ステップｓ１１において、第１判定及び第６判定の少なくとも一方でＹＥＳと判定すると、ステップｓ１２を実行し、その後同様に動作する。一方で、制御部１００は、ステップｓ１１において、第１判定及び第６判定の両方でＮＯと判定すると、ステップｓ１４を実行し、その後同様に動作する。 When the control unit 100 determines YES in at least one of the first determination and the sixth determination in step s11, the control unit 100 executes step s12 and then operates in the same manner. On the other hand, if the control unit 100 determines NO in both the first determination and the sixth determination in step s11, the control unit 100 executes step s14 and then operates in the same manner.
　制御部１００は、加速度センサ１５０の出力信号に基づいて、電子機器１のユーザが車両に乗っているか否かを判定することができる。以下に第６判定について詳細に説明する。 The control unit 100 can determine whether or not the user of the electronic device 1 is on the vehicle based on the output signal of the acceleration sensor 150. Hereinafter, the sixth determination will be described in detail.
　本実施例では、制御部１００は、ユーザの移動手段を特定することができる。制御部１００は、例えば、ユーザが歩いて移動しているのか、走って移動しているのか、自転車で移動しているのか、自動車で移動しているのか、バスで移動しているのか、電車で移動しているのかを特定することができる。つまり、制御部１００は、ユーザの移動手段が、「歩き」であるのか、「走り」であるのか、「自転車」であるのか、「自動車」であるのか、「バス」であるのか、「電車」であるのかを特定することができる。なお、制御部１００が特定可能なユーザの移動手段はこの限りではない。 In the present embodiment, the control unit 100 can specify the moving means of the user. For example, the control unit 100 determines whether the user is walking, moving, running, moving by bicycle, moving by car, moving by bus, train You can specify whether you are moving. That is, the control unit 100 determines whether the user's moving means is “walking”, “running”, “bicycle”, “automobile”, “bus”, “train” Can be specified. The user moving means that can be specified by the control unit 100 are not limited to this.
　ここで、電子機器１の加速度が、当該電子機器１を持つユーザの移動手段に応じた固有の時間変化のパターンを示すことが知られている。制御部１００は、加速度センサ１５０で検出される加速度の時間変化のパターンが、「歩き」に応じたパターンを示す場合には、ユーザの移動手段が「歩き」であると特定する。また、制御部１００は、加速度センサ１５０で検出される加速度の時間変化のパターンが、「走り」に応じたパターンを示す場合には、ユーザの移動手段が「走り」であると特定する。また、制御部１００は、加速度センサ１５０で検出される加速度の時間変化のパターンが、「自転車」に応じたパターンを示す場合には、ユーザの移動手段が「自転車」であると特定する。「自動車」、「バス」及び「電車」についても同様である。 Here, it is known that the acceleration of the electronic device 1 shows a unique temporal change pattern according to the moving means of the user having the electronic device 1. When the pattern of the time change of acceleration detected by the acceleration sensor 150 indicates a pattern corresponding to “walking”, the control unit 100 specifies that the user's moving means is “walking”. In addition, when the pattern of the time change of acceleration detected by the acceleration sensor 150 indicates a pattern corresponding to “running”, the control unit 100 specifies that the user's moving means is “running”. In addition, when the acceleration time change pattern detected by the acceleration sensor 150 indicates a pattern corresponding to “bicycle”, the control unit 100 specifies that the user's moving means is “bicycle”. The same applies to “automobile”, “bus”, and “train”.
　また本実施例では、制御部１００は、加速度センサ１５０の出力信号に基づいて、ユーザが停止しているか否かも判定することができる。 In this embodiment, the control unit 100 can also determine whether the user is stopped based on the output signal of the acceleration sensor 150.
　ステップｓ１１での第６判定において、制御部１００は、加速度センサ１５０の出力信号に基づいて、ユーザが停止しているか否かを判定する。制御部１００は、ユーザが停止していると判定すると、ユーザは車両に乗っていないと判定する。一方で、制御部１００は、ユーザが停止していないと判定すると、ユーザの移動手段を特定する。制御部１００は、特定した移動手段が、「自転車」、「自動車」、「バス」及び「電車」のいずれかである場合には、ユーザが車両に乗っていると判定する。一方で、制御部１００は、特定した移動手段が、「歩き」及び「走り」のいずれかである場合には、ユーザが車両に乗っていないと判定する。 In the sixth determination at step s11, the control unit 100 determines whether or not the user has stopped based on the output signal of the acceleration sensor 150. When determining that the user is stopped, the control unit 100 determines that the user is not on the vehicle. On the other hand, if the control unit 100 determines that the user has not stopped, the control unit 100 identifies the moving means of the user. The control unit 100 determines that the user is on the vehicle when the identified moving means is any one of “bicycle”, “automobile”, “bus”, and “train”. On the other hand, the control unit 100 determines that the user is not on the vehicle when the identified moving means is either “walking” or “running”.
　このようにして、制御部１００は、ユーザが車両に乗っているか否かを判定する第６判定を行うことができる。 Thus, the control unit 100 can perform the sixth determination for determining whether or not the user is on the vehicle.
　なお、制御部１００は、第１判定及び第６判定の両方でＹＥＳと判定するとステップｓ１２を実行し、第１判定及び第６判定の少なくとも一方でＮＯと判定するとステップｓ１４を実行してもよい。 The controller 100 may execute step s12 when determining YES in both the first determination and the sixth determination, and execute step s14 when determining NO in at least one of the first determination and the sixth determination. .
　また、第１実施例等と同様に、本実施例のステップｓ１１では第１判定が実行されなくてもよい。また、ステップｓ１１では、第１判定、第４判定及び第５判定の少なくとも一つと、第６判定とが実行されてもよい。つまり、制御部１００は、第１条件、第４条件及び第５条件の少なくとも一つと、第６条件とに基づいて、画像位置制御を行うか否かを決定してもよい。 Further, as in the first embodiment, the first determination may not be executed in step s11 of the present embodiment. In step s11, at least one of the first determination, the fourth determination, and the fifth determination, and the sixth determination may be executed. That is, the control unit 100 may determine whether to perform image position control based on at least one of the first condition, the fourth condition, the fifth condition, and the sixth condition.
　このように、本実施例では、電子機器１のユーザが車両に乗っているか否かという第６条件に基づいて、画像位置制御が行われるか否かが決定される。これにより、第１実施例等と同様に、画像位置制御の実効性が向上するとともに、電子機器１の消費電力が低減する。また、ユーザが表示画面１２１を見たときに違和感を受ける可能性を低減することができる。 Thus, in the present embodiment, whether or not the image position control is performed is determined based on the sixth condition whether or not the user of the electronic device 1 is on the vehicle. As a result, as in the first embodiment, the effectiveness of the image position control is improved and the power consumption of the electronic device 1 is reduced. Further, it is possible to reduce the possibility that the user feels uncomfortable when viewing the display screen 121.
　また、第６条件を含む複数の条件に基づいて、画像位置制御が行われるか否かが決定されることにより、画像位置制御の実効性がさらに向上するとともに、電子機器１の消費電力がさらに低減する。 Further, by determining whether or not the image position control is performed based on a plurality of conditions including the sixth condition, the effectiveness of the image position control is further improved, and the power consumption of the electronic device 1 is further increased. Reduce.
　なお、ユーザの移動手段が「走り」である場合には、「歩き」である場合によりも、電子機器１に振動がかかり易くなる。つまり、ユーザが歩いているときよりも速く移動しているときには、電子機器１に振動がかかり易くなる。よって、ユーザが速く移動しているときに画像位置制御が実行されることは有効である。 In addition, when the user's moving means is “running”, the electronic device 1 is more likely to be vibrated than when the user is “walking”. That is, when the user moves faster than when walking, the electronic device 1 is likely to be vibrated. Therefore, it is effective that the image position control is executed when the user is moving fast.
　そこで、制御部１００は、決定処理において、上述の第６条件の代りに、ユーザが速く移動しているか否かという第７条件を使用してもよい。この場合、ステップｓ１１では、上記の第６判定の代りに、ユーザが速く移動しているか否かを判定する第７判定が実行される。第７判定では、制御部１００は、第６判定と同様に、まず、ユーザが停止しているか否かを判定する。制御部１００は、ユーザが停止していると判定すると、第７判定の結果をＮＯとする。一方で、制御部１００は、ユーザが停止していないと判定すると、ユーザの移動手段を特定する。制御部１００は、特定した移動手段が、「走り」、「自転車」、「自動車」、「バス」及び「電車」のいずれかである場合には、ユーザが速く移動していると判定する。これにより、第７判定の結果がＹＥＳとなる。一方で、制御部１００は、特定した移動手段が「歩き」である場合には、第７判定の結果をＮＯとする。 Therefore, in the determination process, the control unit 100 may use a seventh condition as to whether or not the user is moving fast, instead of the sixth condition described above. In this case, in step s11, instead of the sixth determination, a seventh determination is performed to determine whether or not the user is moving fast. In the seventh determination, similarly to the sixth determination, the control unit 100 first determines whether or not the user has stopped. If the control unit 100 determines that the user is stopped, the result of the seventh determination is NO. On the other hand, if the control unit 100 determines that the user has not stopped, the control unit 100 identifies the moving means of the user. The control unit 100 determines that the user is moving fast when the specified moving means is any one of “running”, “bicycle”, “automobile”, “bus”, and “train”. As a result, the result of the seventh determination is YES. On the other hand, when the identified moving means is “walking”, the control unit 100 sets the result of the seventh determination to NO.
　このように、電子機器１のユーザが速く移動しているか否かという第７条件に基づいて、画像位置制御が行われるか否かが決定されることにより、画像位置制御の実効性が向上するとともに、電子機器１の消費電力が低減する。また、ユーザが表示画面１２１を見たときに違和感を受ける可能性を低減することができる。 Thus, the effectiveness of the image position control is improved by determining whether or not the image position control is performed based on the seventh condition whether or not the user of the electronic device 1 is moving fast. At the same time, the power consumption of the electronic device 1 is reduced. Further, it is possible to reduce the possibility that the user feels uncomfortable when viewing the display screen 121.
　また、第７条件を含む複数の条件に基づいて、画像位置制御が行われるか否かが決定されることにより、画像位置制御の実効性がさらに向上するとともに、電子機器１の消費電力がさらに低減する。 Further, by determining whether or not image position control is performed based on a plurality of conditions including the seventh condition, the effectiveness of the image position control is further improved, and the power consumption of the electronic device 1 is further increased To reduce.
　＜第４実施例＞
　ユーザは、電子機器１を持つ手を大きく動かすことがある。例えば、ユーザは、机の上あるいは床の上にある電子機器１を持ち上げようとする場合、電子機器１を持つ手を大きく動かすことがある。また、ユーザは、電子機器１の表示画面１２１を他人に見せようとして、電子機器１を持つ手を大きく動かすことがある。ユーザは、電子機器１を持つ手を大きく動かしている場合には、表示画面１２１を見ていない可能性が高い。したがって、電子機器１を持つ手を大きく動かしている場合に画像位置制御を行う必要性は乏しいと言える。 <Fourth embodiment>
The user may move the hand holding the electronic device 1 greatly. For example, when trying to lift the electronic device 1 on the desk or the floor, the user may move the hand holding the electronic device 1 greatly. In addition, the user may move the hand holding the electronic device 1 greatly in an attempt to show the display screen 121 of the electronic device 1 to another person. When the user moves the hand holding the electronic device 1 greatly, there is a high possibility that the user does not see the display screen 121. Therefore, it can be said that there is little need to perform image position control when the hand holding the electronic device 1 is moved greatly.
　一方で、ユーザが、電子機器１を持つ手を大きく動かしている場合には、電子機器１の加速度が大きくなる可能性が高い。 On the other hand, if the user moves the hand holding the electronic device 1 greatly, the acceleration of the electronic device 1 is likely to increase.
　そこで、本実施例に係る決定処理では、電子機器１に大きな加速度が発生していないか否かという第８条件が使用される。 Therefore, in the determination process according to the present embodiment, an eighth condition is used as to whether or not a large acceleration is generated in the electronic device 1.
　本実施例では、上述の図８～１０に示されるステップｓ１１において、制御部１００は、第１判定を行うとともに、電子機器１に大きな加速度が発生していないか否かを判定する第８判定を行う。 In the present embodiment, in step s11 shown in FIGS. 8 to 10 described above, the control unit 100 performs the first determination and determines whether or not a large acceleration has occurred in the electronic device 1 as an eighth determination. I do.
　制御部１００は、加速度センサ１５０の出力信号に基づいて、電子機器１に大きな加速度が発生していないか否かを判定することができる。第８判定において、制御部１００は、まず、加速度センサ１５０の出力信号に基づいて、Ｘ軸方向での電子機器１の加速度と、Ｙ軸方向での電子機器１の加速度と、Ｚ軸方向での電子機器１の加速度とを合成した合成加速度を求める。そして、制御部１００は、合成加速度の大きさがしきい値以上であるか否かを判定する。制御部１００は、合成加速度の大きさがしきい値以上であると判定すると、電子機器１に大きな加速度が発生していると判定する。これにより、第８判定の結果がＮＯとなる。一方で、制御部１００は、合成加速度の大きさがしきい値よりも小さいと判定すると、第８判定の結果をＹＥＳとする。 The control unit 100 can determine whether or not a large acceleration is generated in the electronic device 1 based on the output signal of the acceleration sensor 150. In the eighth determination, the control unit 100 first determines the acceleration of the electronic device 1 in the X-axis direction, the acceleration of the electronic device 1 in the Y-axis direction, and the Z-axis direction based on the output signal of the acceleration sensor 150. The combined acceleration obtained by combining the acceleration of the electronic device 1 is obtained. Then, the control unit 100 determines whether or not the magnitude of the combined acceleration is greater than or equal to a threshold value. When determining that the magnitude of the combined acceleration is equal to or greater than the threshold value, the control unit 100 determines that a large acceleration is generated in the electronic device 1. As a result, the result of the eighth determination is NO. On the other hand, when determining that the magnitude of the combined acceleration is smaller than the threshold value, the control unit 100 sets the result of the eighth determination to YES.
　制御部１００は、ステップｓ１１において、第１判定及び第８判定の少なくとも一方でＹＥＳと判定すると、ステップｓ１２を実行し、その後同様に動作する。一方で、制御部１００は、ステップｓ１１において、第１判定及び第８判定の両方でＮＯと判定すると、ステップｓ１４を実行し、その後同様に動作する。 When the control unit 100 determines YES in at least one of the first determination and the eighth determination in step s11, the control unit 100 executes step s12 and then operates in the same manner. On the other hand, if the control unit 100 determines NO in both the first determination and the eighth determination in step s11, the control unit 100 executes step s14 and then operates in the same manner.
　なお制御部１００は、第１判定及び第８判定の両方でＹＥＳと判定するとステップｓ１２を実行し、第１判定及び第８判定の少なくとも一方でＮＯと判定するとステップｓ１４を実行してもよい。 The control unit 100 may execute step s12 when determining YES in both the first determination and the eighth determination, and execute step s14 when determining NO in at least one of the first determination and the eighth determination.
　また、第１実施例等と同様に、本実施例のステップｓ１１では第１判定が実行されなくてもよい。またステップｓ１１では、第１判定、第４判定、第５判定及び第６判定の少なくとも一つと、第８判定とが実行されてもよい。またステップｓ１１では、第１判定、第４判定、第５判定及び第７判定の少なくとも一つと、第８判定とが実行されてもよい。 Further, as in the first embodiment, the first determination may not be executed in step s11 of the present embodiment. In step s11, at least one of the first determination, the fourth determination, the fifth determination, and the sixth determination, and the eighth determination may be executed. In step s11, at least one of the first determination, the fourth determination, the fifth determination, and the seventh determination, and the eighth determination may be executed.
　このように、本実施例では、電子機器１に大きな加速度が発生しているか否かという第８条件に基づいて、画像位置制御が行われるか否かが決定される。これにより、画像位置制御の実効性が向上するとともに、電子機器１の消費電力が低減する。 Thus, in this embodiment, whether or not image position control is performed is determined based on the eighth condition of whether or not a large acceleration is generated in the electronic device 1. Thereby, the effectiveness of the image position control is improved and the power consumption of the electronic device 1 is reduced.
　また、第８条件を含む複数の条件に基づいて、画像位置制御が行われるか否かが決定されることにより、画像位置制御の実効性がさらに向上するとともに、電子機器１の消費電力がさらに低減する。 Further, by determining whether or not image position control is performed based on a plurality of conditions including the eighth condition, the effectiveness of the image position control is further improved, and the power consumption of the electronic device 1 is further increased To reduce.
　＜第５実施例＞
　制御部１００は、決定処理において複数の条件を使用する場合には、当該複数の条件のそれぞれに設定された重み付けと、当該複数の条件とに基づいて、画像位置制御を行うか否かを決定してもよい。 <Fifth embodiment>
When using a plurality of conditions in the determination process, the control unit 100 determines whether to perform image position control based on the weights set for each of the plurality of conditions and the plurality of conditions. May be.
　例えば、決定処理において、第１条件、第４条件、第５条件、第６条件及び第８条件が使用される場合を考える。つまり、ステップｓ１１において、第１判定、第４判定、第５判定、第６判定及び第８判定が実行される場合を考える。この場合、例えば、表示画面１２１の向きに関する第１条件の重み付けと、加速度の大きさに関する第８条件の重み付けを大きくする。また、ユーザの移動手段に関する第６条件の重み付けを中程度とする。そして、電子機器１の微細な振動に関する第４条件の重み付けと、電子機器１の振動パターンに関する第５条件の重み付けを小さくする。一例として、第１及び第８条件の重み付けを５０、第６条件の重み付けを３０、第４及び第５条件の重み付けを１０とする。各条件の重み付けの値はこれに限られない。 For example, consider a case where the first condition, the fourth condition, the fifth condition, the sixth condition, and the eighth condition are used in the determination process. That is, consider the case where the first determination, the fourth determination, the fifth determination, the sixth determination, and the eighth determination are executed in step s11. In this case, for example, the weighting of the first condition regarding the orientation of the display screen 121 and the weighting of the eighth condition regarding the magnitude of acceleration are increased. Further, the weighting of the sixth condition relating to the moving means of the user is assumed to be medium. And the weighting of the 4th condition regarding the fine vibration of the electronic device 1 and the weighting of the 5th condition regarding the vibration pattern of the electronic device 1 are made small. As an example, the weighting of the first and eighth conditions is 50, the weighting of the sixth condition is 30, and the weighting of the fourth and fifth conditions is 10. The weighting value for each condition is not limited to this.
　制御部１００は、ステップｓ１１において、第１判定、第４判定、第５判定、第６判定及び第８判定のうち、その結果がＹＥＳとされた判定に対応する条件の重み付けの合計値を重み付け合計値として求める。そして、制御部１００は、重み付け合計値がしきい値以上のとき、ステップｓ１２を実行して、画像位置制御を行うことを決定する。一方で、制御部１００は、重み付け合計値がしきい値未満のとき、ステップｓ１４を実行して、画像位置制御を行わないと決定する。しきい値は、例えば７０に設定される。しきい値はこれに限られない。 In step s11, the control unit 100 weights the sum of the weights of the conditions corresponding to the determination in which the result is YES among the first determination, the fourth determination, the fifth determination, the sixth determination, and the eighth determination. Calculated as the total value. Then, when the weighted total value is equal to or larger than the threshold value, the control unit 100 determines to perform image position control by executing step s12. On the other hand, when the weighted total value is less than the threshold value, the control unit 100 executes step s14 and determines not to perform image position control. The threshold value is set to 70, for example. The threshold value is not limited to this.
　ステップｓ１１において、第１判定、第４判定、第５判定、第６判定及び第８判定のうち、例えば第１判定及び第６判定でＹＥＳとされたとき、重み付け合計値は８０となり、しきい値（７０）以上となる。この場合には、画像位置制御が行われることが決定される。 In step s11, for example, when YES is determined in the first determination and the sixth determination among the first determination, the fourth determination, the fifth determination, the sixth determination, and the eighth determination, the weighted total value becomes 80, and the threshold value. Value (70) or more. In this case, it is determined that image position control is performed.
　またステップｓ１１において、例えば第４判定及び第６判定でＹＥＳとされたとき、重み付け合計値は４０となり、しきい値（７０）未満となる。この場合には、画像位置制御が行われないことが決定される。 In step s11, for example, when YES is determined in the fourth determination and the sixth determination, the weighted total value is 40, which is less than the threshold (70). In this case, it is determined that image position control is not performed.
　またステップｓ１１において、例えば第５判定及び第８判定でＹＥＳとされたとき、重み付け合計値は６０となり、しきい値（７０）未満となる。この場合には、画像位置制御が行われないことが決定される。 In step s11, for example, when YES is determined in the fifth determination and the eighth determination, the weighted total value is 60, which is less than the threshold value (70). In this case, it is determined that image position control is not performed.
　またステップｓ１１において、例えば第１判定及び第８判定でＹＥＳとされたとき、重み付け合計値は１００となり、しきい値（７０）以上となる。この場合には、画像位置制御が行われることが決定される。 In step s11, for example, when YES is determined in the first determination and the eighth determination, the weighted total value is 100, which is equal to or greater than the threshold (70). In this case, it is determined that image position control is performed.
　このように、制御部１００が、決定処理において、複数の条件のそれぞれに設定された重み付けと、当該複数の条件とに基づいて、画像位置制御を行うか否かを決定することによって、画像位置制御の実効性がさらに向上するとともに、電子機器１の消費電力がさらに低減する。 As described above, the control unit 100 determines whether or not to perform image position control based on the weights set for each of the plurality of conditions and the plurality of conditions in the determination process. The effectiveness of the control is further improved, and the power consumption of the electronic device 1 is further reduced.
　上記の画像位置制御では、制御部１００は、対象画像全体の表示位置を電子機器１の移動に基づいて制御しているが、対象画像のうち、一部の画像だけの表示位置を電子機器１の移動に基づいて制御してもよい。これにより、当該一部の画像についての地球に対する位置が動きにくくなる。よって、当該一部の画像の視認性が向上する。図５の例では、制御部１００は、例えば、対象画像４００のうち、文字列４０１の画像だけの表示位置を電子機器１の移動に基づいて制御してもよい。これにより、文字列４０１の画像についての地球に対する位置が動きにくくなり、文字列４０１の画像の視認性が向上する。 In the image position control described above, the control unit 100 controls the display position of the entire target image based on the movement of the electronic device 1. You may control based on movement of. Thereby, the position with respect to the earth about the said one part image becomes difficult to move. Therefore, the visibility of the partial image is improved. In the example of FIG. 5, for example, the control unit 100 may control the display position of only the image of the character string 401 in the target image 400 based on the movement of the electronic device 1. As a result, the position of the image of the character string 401 with respect to the earth is difficult to move, and the visibility of the image of the character string 401 is improved.
　また上記の例では、制御部１００は、加速度センサ１５０の出力信号に基づいて電子機器１の移動を特定しているが、他の方法を用いて電子機器１の移動を特定してもよい。制御部１００は、例えば、第２カメラ（アウトカメラ）２００で撮影される画像に基づいて電子機器１の移動を特定してもよい。この場合、制御部１００は、例えば、第２カメラ２００での撮影画像に含まれる所定の画像の移動量及び移動方向を、当該撮影画像に対して画像処理を行うことによって特定する。そして、制御部１００は、特定した移動量及び移動方向を、電子機器１の移動量及び移動方向とする。また制御部１００は、第１カメラ（インカメラ）１９０で撮影される画像に基づいて電子機器１の移動を特定してもよい。 In the above example, the control unit 100 specifies the movement of the electronic device 1 based on the output signal of the acceleration sensor 150. However, the movement of the electronic device 1 may be specified using another method. For example, the control unit 100 may specify the movement of the electronic device 1 based on an image captured by the second camera (out camera) 200. In this case, for example, the control unit 100 specifies the moving amount and moving direction of a predetermined image included in the image captured by the second camera 200 by performing image processing on the captured image. Then, the control unit 100 sets the identified movement amount and movement direction as the movement amount and movement direction of the electronic device 1. Further, the control unit 100 may specify the movement of the electronic device 1 based on an image captured by the first camera (in camera) 190.
　また制御部１００が、処理能力が高いメインＣＰＵ１０１ｍと、処理能力が低いサブＣＰＵ１０１ｓを備えている場合には、図１１に示されるように、メインＣＰＵ１０１ｍが駆動回路３００を制御し、メインＣＰＵ１０１ｍが加速度センサ１５０の出力信号を受け取ってもよい。この場合、決定処理は、メインＣＰＵ１０１ｍで実行されてもよいし、サブＣＰＵ１０１ｓで実行されてもよい。また、画像表示制御では、メインＣＰＵ１０１ｍが上述の図６のステップｓ１，ｓ３を実行する。そして、上述のステップｓ４において、メインＣＰＵ１０１ｍは、対象画像を示す画像データを元にして、観測移動量及び観測移動方向に基づいて、対象画像のうち、表示画面１２１に実際に表示される部分を示す画像データを生成する。そして、駆動回路３００が、メインＣＰＵ１０１ｍで生成された画像データに基づいて表示パネル１２２を駆動する。また、ステップｓ４では、メインＣＰＵ１０１ｍは、対象画像を示す画像データと、取得した観測移動量及び観測移動方向とを駆動回路３００に出力してよい。そして、駆動回路３００は、メインＣＰＵ１０１ｍから受け取った画像データ、観測移動量及び観測移動方向に基づいて、表示パネル１２２を駆動してもよい。処理能力が高いメインＣＰＵ１０１ｍの回路規模は、処理能力が低いサブＣＰＵ１０１ｓの回路規模よりも大きくなっている。 When the control unit 100 includes a main CPU 101m having a high processing capability and a sub CPU 101s having a low processing capability, the main CPU 101m controls the drive circuit 300 and the main CPU 101m accelerates as shown in FIG. An output signal of the sensor 150 may be received. In this case, the determination process may be executed by the main CPU 101m or the sub CPU 101s. In the image display control, the main CPU 101m executes steps s1 and s3 shown in FIG. In step s4 described above, the main CPU 101m selects a portion of the target image that is actually displayed on the display screen 121 based on the observation movement amount and the observation movement direction based on the image data indicating the target image. The image data shown is generated. Then, the drive circuit 300 drives the display panel 122 based on the image data generated by the main CPU 101m. In step s4, the main CPU 101m may output the image data indicating the target image and the acquired observation movement amount and observation movement direction to the drive circuit 300. Then, the drive circuit 300 may drive the display panel 122 based on the image data, the observation movement amount, and the observation movement direction received from the main CPU 101m. The circuit scale of the main CPU 101m with high processing capability is larger than the circuit scale of the sub CPU 101s with low processing capability.
　また図１２に示されるように、サブＣＰＵ１０１ｓが駆動回路３００を制御し、サブＣＰＵ１０１ｓが加速度センサ１５０の出力信号を受け取ってもよい。この場合、決定処理は、メインＣＰＵ１０１ｍで実行されてもよいし、サブＣＰＵ１０１ｓで実行されてもよい。また、画像表示制御では、サブＣＰＵ１０１ｓが上述のステップｓ１，ｓ３を実行する。そして、上述のステップｓ４において、サブＣＰＵ１０１ｓは、対象画像を示す画像データを元にして、観測移動量及び観測移動方向に基づいて、対象画像のうち、表示画面１２１に実際に表示される部分を示す画像データを生成する。そして、駆動回路３００が、サブＣＰＵ１０１ｓで生成された画像データに基づいて表示パネル１２２を駆動する。また、ステップｓ４では、サブＣＰＵ１０１ｓは、対象画像を示す画像データと、取得した観測移動量及び観測移動方向とを駆動回路３００に出力してもよい。そして、駆動回路３００は、サブＣＰＵ１０１ｓから受け取った画像データ、観測移動量及び観測移動方向に基づいて、表示パネル１２２を駆動してもよい。また、ステップｓ４では、メインＣＰＵ１０１ｍが、対象画像を示す画像データを生成して駆動回路３００に出力し、サブＣＰＵ１０１ｓが取得した観測移動量及び観測移動方向を駆動回路３００に出力してもよい。そして、駆動回路３００は、メインＣＰＵ１０１ｍから受け取った画像データと、サブＣＰＵ１０１ｓから受け取った観測移動量及び観測移動方向に基づいて、表示パネル１２２を駆動してもよい。 Further, as shown in FIG. 12, the sub CPU 101s may control the drive circuit 300, and the sub CPU 101s may receive the output signal of the acceleration sensor 150. In this case, the determination process may be executed by the main CPU 101m or the sub CPU 101s. In the image display control, the sub CPU 101s executes the above steps s1 and s3. In step s4 described above, the sub CPU 101s selects a portion of the target image that is actually displayed on the display screen 121 based on the observation movement amount and the observation movement direction based on the image data indicating the target image. The image data shown is generated. Then, the drive circuit 300 drives the display panel 122 based on the image data generated by the sub CPU 101s. In step s4, the sub CPU 101s may output the image data indicating the target image and the acquired observation movement amount and observation movement direction to the drive circuit 300. Then, the drive circuit 300 may drive the display panel 122 based on the image data, the observation movement amount, and the observation movement direction received from the sub CPU 101s. In step s4, the main CPU 101m may generate image data indicating the target image and output the image data to the drive circuit 300, and output the observation movement amount and the observation movement direction acquired by the sub CPU 101s to the drive circuit 300. Then, the drive circuit 300 may drive the display panel 122 based on the image data received from the main CPU 101m and the observation movement amount and observation movement direction received from the sub CPU 101s.
　サブＣＰＵ１０１ｓの回路規模は、メインＣＰＵ１０１ｍの回路規模よりも小さいことから、サブＣＰＵ１０１ｓとメインＣＰＵ１０１ｍが同じ処理を行う場合であっても、サブＣＰＵ１０１ｓの消費電力は、メインＣＰＵ１０１ｍの消費電力よりも小さくなる。よって、制御部１００が、サブＣＰＵ１０１ｓを使用して画像位置制御及び決定処理を行う場合には、メインＣＰＵ１０１ｍを使用して画像位置制御及び決定処理を行う場合より、電子機器１の消費電力を低減することができる。また、制御部１００が、サブＣＰＵ１０１ｓを使用して画像位置制御及び決定処理を行う場合には、メインＣＰＵ１０１ｍが処理を実行している場合、あるいはメインＣＰＵ１０１ｍがスリープ状態である場合にも、画像位置制御及び決定処理の実行が可能性となる。 Since the circuit scale of the sub CPU 101s is smaller than the circuit scale of the main CPU 101m, even when the sub CPU 101s and the main CPU 101m perform the same processing, the power consumption of the sub CPU 101s is smaller than the power consumption of the main CPU 101m. . Therefore, when the control unit 100 performs image position control and determination processing using the sub CPU 101s, the power consumption of the electronic device 1 is reduced compared to when image position control and determination processing is performed using the main CPU 101m. can do. In addition, when the control unit 100 performs image position control and determination processing using the sub CPU 101s, the image position is also detected when the main CPU 101m is executing processing or when the main CPU 101m is in the sleep state. Execution of control and decision processing becomes possible.
