Description
本発明の第１の態様は、
ユーザの頭部に固定される表示装置であって、
焦点距離を変更可能な撮像手段と、
前記撮像手段によって撮像された画像の一部を表示範囲として表示する表示手段と、
前記表示装置の姿勢を検出する姿勢検出手段と、
前記姿勢検出手段で検出された前記姿勢の変化と、前記焦点距離とに基づいて、前記表示範囲の位置を制御する制御手段と、を有することを特徴とする表示装置である。
A first aspect of the present invention is
A display device fixed to a user's head ,
imaging means capable of changing the focal length;
display means for displaying a portion of the image captured by the imaging means as a display range;
attitude detection means for detecting the attitude of the display device;
and control means for controlling the position of the display range based on the change in posture detected by the posture detection means and the focal length.
本発明の第２の態様は、
焦点距離を変更可能な撮像手段と、前記撮像手段によって撮像された画像の一部を表示範囲として表示する表示手段とを有し、ユーザの頭部に固定される表示装置の制御方法であって、
前記表示装置の姿勢を検出する姿勢検出ステップと、
前記姿勢検出手段で検出された前記姿勢の変化と、前記焦点距離とに基づいて、前記表示範囲の位置を制御する制御ステップと、を有することを特徴とする制御方法である。
A second aspect of the present invention is
A control method for a display device fixed to a user's head, the display device having imaging means capable of changing a focal length and display means for displaying a part of an image captured by the imaging means as a display range, comprising: ,
an orientation detection step of detecting an orientation of the display device;
The control method includes a control step of controlling the position of the display range based on the change in posture detected by the posture detection means and the focal length.
また、パン方向へ表示範囲を移動させる制御方法は、チルト方向へ表示範囲を移動させる制御方法と異なってもよい。例えば、パン方向とチルト方向の一方への表示範囲の制御は第１の敏感度で行い、パン方向とチルト方向の他方への表示範囲の制御は第１の敏感度と異なる第２の敏感度で行ってもよい。
Also, the control method for moving the display range in the pan direction may be different from the control method for moving the display range in the tilt direction. For example, control of the display range in one of the pan and tilt directions is performed with a first sensitivity, and control of the display range in the other of the pan and tilt directions is performed with a second sensitivity different from the first sensitivity. You can go in degrees.
Ｓ１０６では、実施例１と同様に、Ｓ１０４で検出された角度θに基づく移動量Ａ２が決定（算出）される。実施例２では、角度θと敏感度Ｓから、移動量Ａ２＝－（１－Ｓ）×θが算出される。このため、敏感度Ｓ＝１の場合には、表示範囲の移動制御を行わない移動量Ａ２＝０が算出される。敏感度Ｓが１よりも小さい場合には、敏感度Ｓが小さいほど絶対値が大きく且つ角度θとは正負が逆の移動量Ａ２、すなわち敏感度Ｓが小さいほど電子双眼鏡１０（頭部）の姿勢の変化による表示方向の変化を小さくする移動量Ａ２が算出される。敏感度Ｓが１よりも大きい場合には、敏感度Ｓが大きいほど絶対値が大きく且つ角度θと正負が同じ移動量Ａ２、すなわち敏感度Ｓが大きいほど電子双眼鏡１０（頭部）の姿勢の変化による表示方向の変化を大きくする移動量Ａ２が算出される。 In S106, as in the first embodiment, the movement amount A2 is determined (calculated) based on the angle θ detected in S104. In the second embodiment, the movement amount A2=-(1-S).times..theta. is calculated from the angle .theta. Therefore, when the sensitivity S=1, the movement amount A2=0 is calculated in which movement control of the display range is not performed. When the sensitivity S is smaller than 1, the smaller the sensitivity S, the larger the absolute value and the movement amount A2 that is opposite in sign to the angle θ. A movement amount A2 is calculated that reduces the change in the display direction due to the change in posture. When the sensitivity S is greater than 1, the greater the sensitivity S, the larger the absolute value and the movement amount A2 having the same sign as the angle θ. A movement amount A2 that increases the change in the display direction due to the change is calculated.
