Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a simplified external view showing the basic structure of a three-dimensional viewpoint parameter designating apparatus according to an embodiment of the present invention.

This three-dimensional viewpoint parameter designating device includes a display device 2 having a screen portion 2a for displaying an image,
An operation unit 100 including operation keys for designating a mode of an image to be displayed on the screen unit 2a and an image are input (here, movement with respect to one image in a predetermined image mode, movement from one image to another). Mouse 1 having three buttons 3 to 5 (for changing to an image, etc.).

Here, the display device 2 has two windows, a viewpoint control button window 6 including buttons for changing preset three-dimensional viewpoint parameters and a display window 7 for performing three-dimensional display. Can be displayed as a frame on the screen 2a, and the input from the mouse 1 and the designation of a button in the view control button window 6 can be performed.
Alternatively, the system configuration is such that the three-dimensional viewpoint parameter is changed when the mouse 1 is independently input, and the three-dimensional display of the image based on the changed three-dimensional viewpoint parameter is performed on the display window 7 or the full-scale screen 2a. (Display means).

Therefore, the display device 2 has a three-dimensional viewpoint parameter changing unit for changing the three-dimensional viewpoint parameter, a viewpoint control button window 6 and a display window 7 for displaying a frame on the screen 2a. Frame display means, three-dimensional conversion means for performing three-dimensional conversion for three-dimensional display based on the changed three-dimensional viewpoint parameter, and the three-dimensional converted image on the display window 7 or full-scale screen 2a. And a distribution output means for three-dimensional display.

That is, this three-dimensional viewpoint parameter designating device is used to designate and input buttons on the view control button window 6 framed on the screen 2a of the display device 2 and the mouse 1.
Mouse 1 with any one of each button 3-5 pressed
The three-dimensional viewpoint parameter is changed in a composite manner by the input obtained by moving the mouse, or any one of the buttons 3 to 5 of the mouse 1 is pressed and the remaining buttons are pressed to combine them. The three-dimensional viewpoint parameter is independently changed by an input obtained by moving the mouse 1 according to a predetermined operation procedure (three-dimensional viewpoint parameter changing unit).

Here, first, the designation input of the button on the window 6 for the viewpoint control button and the respective buttons 3 to 5 of the mouse 1 are performed.
The change of the three-dimensional viewpoint parameter performed based on the composite input with the input by moving the mouse 1 while pressing any of the above will be described.

As shown in FIG. 2, the viewpoint control button window 6 includes three-dimensional viewpoint parameter operation buttons 8 to 1.

While pressing the selected button, the mouse 1 body is moved up, down, left and right.

At this time, as a matter of recognition to the user, a three-dimensional display corresponding to the change value due to the change of the three-dimensional viewpoint parameter is displayed on the display window 7. While the button selected by the mouse 1 is being pressed, the cursor on the display window 7 does not move even if the body of the mouse 1 is moved, and the three-dimensional viewpoint changed by releasing the button of the mouse 1 The parameters are confirmed.

Normally, there are seven parameters for controlling the three-dimensional viewpoint, but the movement amount of the mouse 1 is two in the vertical direction and the horizontal direction. Therefore, in the window 6 for the viewpoint control button, six types of buttons 8 to 13 are provided and the mouse 1
The vertical and horizontal movement amounts of the three types make it possible to distinguish which item of the three-dimensional viewpoint parameter is changed and how.

The following will specifically describe how the three-dimensional viewpoint parameters change as the mouse 1 moves vertically and horizontally when the six types of buttons 8 to 13 in the viewpoint control button window 6 are designated. .

The button 8 changes the three-dimensional viewpoint parameter as shown in the following expression (3).

[0029]

[Equation 3] Here, Mx represents the lateral movement amount of the mouse 1, and My
Represents the amount of movement of the mouse 1 in the vertical direction. Also, Ca, Cb
Is a constant set to an appropriate value for adjusting the sensitivity of the mouse 1.

When the viewpoint parameters are changed in this manner, the user can change the viewpoint direction to the left or right by moving the mouse 1 in the horizontal direction while keeping the viewpoint position. Further, the user can move the mouse 1 in the vertical direction in the direction in which he / she is currently facing without moving the horizontal height. This is just like a feeling of walking around in a three-dimensional space and observing an image three-dimensionally displayed on the display window 7.

The button 9 changes the three-dimensional viewpoint parameter as shown in the following equation (4).

[0032]

[Equation 4] In the case of this change, the user moves left and right without changing the viewpoint direction and viewpoint height by moving the mouse 1 in the horizontal direction, and moves the viewpoint height up and down without changing the viewpoint direction by moving the mouse 1 in the vertical direction. It can be moved. That is, the button 9 is mainly used when changing the height of the viewpoint.

The button 10 changes the three-dimensional viewpoint parameter as shown in the following equation (5).

[0034]

[Equation 5] According to this change, the user can rotate the mouse 1 vertically and horizontally without moving the viewpoint position by moving the mouse 1 vertically and horizontally. This button 10 is mainly used to change the vertical direction of the viewpoint.

The button 11 changes the three-dimensional viewpoint parameter as shown in the following equation (6).

[0036]

[Equation 6] In the case of this change, the user moves the mouse 1 in the horizontal direction by changing the viewpoint position to the left or right as in the case of the button 9 described above, but the mouse 1 moves in the vertical direction to move in the direction in which the viewpoint is currently facing. You can go back. Therefore,
The viewpoint direction does not change here.

The button 12 changes the three-dimensional viewpoint parameter as shown in the following equation (7).

[0038]

[Equation 7] According to this change, the user can rotate the viewpoint around the viewpoint direction by moving the mouse 1 in the horizontal direction, and can move forward and backward in the viewpoint direction by moving the mouse 1 in the vertical direction.

The button 13 changes the three-dimensional viewpoint parameter as shown in the following equation (8).

[0040]

[Equation 8] Here, Cc is a constant for adjusting the sensitivity of mouse 1. In the case of this change, the user can control the viewing angle by moving the mouse 1 in the vertical direction.

The three-dimensional viewpoint parameter designating apparatus for changing such three-dimensional viewpoint parameters is easy to handle and can quickly specify and change the desired three-dimensional viewpoint parameter. Incidentally, since the viewpoint parameters for controlling the three-dimensional viewpoint usually have their respective effective ranges, if the movement of one mouse deviates from the effective range as a result of the above-mentioned change processing, it should be kept within the effective range. It is necessary to readjust each viewpoint parameter.

Next, the change of the three-dimensional viewpoint parameter which is performed based on only the single input from the mouse 1 will be described.

Here, each button 3 of the mouse 1 is mainly used.

Such an operation procedure is for obtaining the function of selecting or moving the image displayed on the display window 7 with the left button 3 and the middle button 4 of the mouse 1 being pressed individually first. It is a thing. Therefore,
In this operation procedure, even if only the left button 3 or the middle button 4 of the mouse 1 is pressed from the state in which none of the buttons 3 to 5 of the mouse 1 are pressed, the three-dimensional viewpoint parameter is not changed.

Therefore, when the user starts changing the three-dimensional viewpoint parameter, the right button 5 of the mouse 1 is pressed. By this operation, if the mouse 1 is moved while the right button 5 is being pressed, the three-dimensional viewpoint parameter is changed.

In a combination of button operations that continue from such a state, when the right button 5 of the mouse 1 is simply pressed, it is the same as when the button 8 in the viewpoint control button window 6 is pressed in the first embodiment. Behavior
When the right button 5 and the middle button 4 of the mouse 1 are both pressed, the same operation as when the button 9 of the view point control window 6 is pressed is obtained.

The right button 5 and the left button 3 of the mouse 1
When is pressed, the same operation as when the button 10 of the viewpoint control button window 6 is pressed is performed, and when the right button 5 is further released and only the left button 3 of the mouse 1 is pressed, the viewpoint control is performed. Button 1 in button window 6
The same operation as when pressing 1 is obtained.

Further, when all of the left button 3, the middle button 4, and the right button 5 of the mouse 1 are pressed, the same operation as when the button 12 of the viewpoint control button window 6 is pressed can be obtained.

Even in the case of such a three-dimensional viewpoint parameter designating device for changing the three-dimensional viewpoint parameter, the target three-dimensional viewpoint parameter can be designated and changed quickly.
