In the three-dimensional image special effect device, a spherical trackball,
It is common to operate a special image using a three-dimensional input device such as a lever-shaped joystick. Various conditions such as the size of a special image and the outline (border) of the special image are given as parameters, and various effects can be achieved by appropriately setting the parameters. Each parameter is displayed on various menus.For example, moving the cursor on the menu to each parameter by operating the trackball, and then using the input keys such as function keys in a different place from the trackball The value of the parameter was set. As described above, conventionally, a trackball for operating a cursor and an input key for setting parameters are separately provided, so that these can be instantly operated with one hand. Parameter setting operation was troublesome. Accordingly, the present invention has been made to solve the above-mentioned problem, and proposes a three-dimensional input device capable of simplifying a parameter setting operation. In order to solve the above-mentioned problems, a three-dimensional input device according to the present invention has a three-dimensional image display effect.

Is a specific parameter specified by operating the trackball.
It is characterized by being operated to set the value of the meter . In order to newly set or change a parameter for determining the state of a special image, the cursor switch 26 shown in FIG. 1 is pressed. Thus, the cursor 51 is displayed on the menu (FIG. 8B) created by the graphic display creating unit 14, and the trackball 21 and the rotating ring 22 serve as parameter setting means. Next, when the trackball 21 is operated,
The rotation amount is detected by the X counter 23 or the Y counter 24, whereby the cursor 51 moves. When the cursor 51 moves into the parameter display area 52, the value of the parameter can be changed. When the rotating ring 22 is rotated in this state, the amount of rotation is detected by the Z counter 25, whereby the value of the parameter is sequentially increased or decreased. When this value reaches a predetermined value, the operation of the rotating ring 22 is stopped,
Next, the value of the parameter is determined by operating the trackball 21 to move the cursor 51 out of the parameter display area 52. By turning on the 3D input switch 27, the special image whose state has been determined in this manner can be operated with the trackball 21 and the rotating ring 22. Next, a three-dimensional input device according to the present invention will be described.
An embodiment applied to a three-dimensional image special effect device will be described in detail with reference to the drawings. FIG. 1 shows a system of a three-dimensional video special effect device 1 to which a three-dimensional input device according to the present invention is applied. In the three-dimensional video special effect device 1, a bus 1
2, a three-dimensional and parameter input unit 13, a graphic display creation unit 14, and a video special effect processing unit 15 are connected. The video special effect processing section 15 applies a special effect to the video signal supplied from the outside and supplies the video signal to the video monitor 16, whereby the video with the special effect is displayed on the screen. Various operations such as moving, rotating, enlarging or reducing the position of the special image projected on the image monitor 16 are performed by the three-dimensional and parameter input unit 13. The three-dimensional and parameter input unit 13 includes a trackball 21 that is spherical and rotatable in an arbitrary direction, and a rotating ring 2 that is disposed on the outer circumference of the trackball 21 and that can rotate along the outer circumference of the trackball 21.
2 are provided. The amount of rotation of the trackball 21 is detected by an X counter 23 and a Y counter 24, and the amount of rotation of the rotating ring 22 is detected by a Z counter 25. Further, here, a cursor switch 26 for setting a parameter for determining a state of a special video described later to be settable,
A 3D input switch 27 for enabling a special image to be operated is provided. The trackball 21, the rotating ring 22, the cursor switch 26 and the 3D input switch 27 are mounted on the panel 2 as shown in FIG. Various other data input switches 28 are attached to the panel 2. In FIG. 1, parameters for determining the state of a special image are displayed in various menus created by a graphic display creating section (setting menu creating means) 14. Each menu is supplied to the menu monitor 17 and displayed on the screen. When the values of the parameters are set by the trackball 21 and the rotating ring 22 as described later, the values are set by the CPU 11.
The video special effect processing unit 1
5 is controlled to determine the state of the special image. FIG. 3 shows the structure of the trackball 21 and the rotating ring 22. In FIG.
The rotating ring 22 is rotatably mounted on a base chassis 32 disposed on a printed circuit board 31. The trackball 21 is rotatable in all directions, and the rotating ring 22 is rotatable in the circumferential direction of the trackball 21. For example, the trackball 21 can input two-dimensional data corresponding to the X-axis and the Y-axis of three-dimensional coordinates, and the rotating ring 22 can input data corresponding to the Z-axis. As shown in FIG. 4, the rotating ring 22 is formed in a ring shape from a plate material having the same thickness, and has an upper surface portion 22a inclined in a conical shape and a flange portion 22b on its upper surface. A step 22c is provided on the outer peripheral surface of the flange 22b. At the lower end of the flange portion 22b, a large number of slits 22d having a predetermined width are provided at regular intervals over the entire circumference as shown in FIG. This slit 22
“d” is disposed so as to cross the groove-shaped optical path portion 33 a of the photo interrupter 33 attached to the base chassis 32. In this rotary ring 22, as shown in FIG. 4, a bearing 34 is disposed on the inner peripheral end face of the upper surface 22a, and a plurality of screws are provided near the bearing 34 of the upper surface 22a as shown in FIG. A part 22e is provided. And
One end of a stopper fitting 35 applied to the lower end surface of the bearing 34 is fixed by a screw portion 22e, whereby the rotating ring 22 is fixed to an outer ring portion 34a of the bearing 34. A fixed ring 36 is arranged on the inner peripheral surface of the rotating ring 22. The fixing ring 36 is supported by a stand pin 37 implanted in the base chassis 32. The inner ring portion 34b of the bearing 34 is firmly fitted into the outer peripheral surface of the fixing ring 36, and the bearing 34 is fixed. Thus, the rotating ring 22 can be rotated with a small force in the circumferential direction, that is, in the direction corresponding to the Z axis. On the other hand, the track ball 21 is
6, three cylindrical support rollers 3 mounted on the base chassis 32 as shown in FIG.
8, 39 and 40 support three points. Then, as shown in FIG.
6 protrudes in a dome shape from the upper end surface, and this protruding portion can be operated from the outside. Further, cylindrical support rollers 38, 39, 4
Reference numeral 0 denotes a center shaft 41 that is rotatably supported, and one of the support rollers 38 is disposed so as to be perpendicular to the X direction in FIG. Another support roller 39 is arranged so as to be perpendicular to the Y direction orthogonal to the X direction. Therefore, the trackball 21
Is rotated by operating a finger, the supporting rollers 38 and 39 also rotate according to the amount of rotation. Next, the track ball 21 and the rotating ring 22
The method of detecting the rotation amount of the motor will be described. Rotating ring 22
The photointerrupter 33 is used for detecting the rotation of, that is, the rotation in the Z direction as described above. In the photo interrupter 33, as shown in FIG. 4, the light emitting element and the light receiving element are arranged on the printed circuit board 31 so as to face each other so as to form a groove-shaped optical path portion 33a. When the rotating ring 22 rotates and the slit 22d crosses the optical path 33a, a pulse-like electric signal is output from the photo interrupter 33. The amount of rotation of the rotating ring 22 can be detected by counting the number of pulses by the Z counter 25 (FIG. 1). The amount of rotation of the trackball 21 in the X or Y direction is detected by the photo interrupters 42 and 43, respectively, as shown in FIG. 6 or FIG. These photo-interrupters 42 and 43 have the same configuration as the above-described photo-interrupter 33, and the light-emitting element and the light-receiving element are arranged to face each other so as to form optical path portions 42a and 43a as shown in FIG. When the cylindrical supporting rollers 38 and 39 rotate, the radial slits 44a of the disk-shaped shutter plate 44 attached thereto rotate the optical path portions 42a and 43a.
A pulse-like electric signal is output by crossing
By counting this by the X counter 23 or the Y counter 24, it becomes possible to detect the amount of rotation of the trackball 21 in the X direction or the Y direction. In FIG. 1, the outputs of the X counter 23, the Y counter 24 and the Z counter 25 are taken into the CPU 11 via the bus 12. Then, the image special effect processing unit 15 is controlled by the instruction of the CPU 11, and the special image on the image monitor 16 is operated in the three-dimensional direction. The parameters for determining the state of the special image, such as the size of the special image created by the image special effect processing unit 15 and the size and color of the border (contour) 50 as shown in FIG. Is created by the graphic display creating unit 14 as shown in the above, and this is displayed on the menu monitor 17 as various menus. FIG. 7B shows an example of a menu display for border setting. In this menu, the width b of the entire border 50 is
Is set as a parameter for determining the width, and "H" is set as a parameter of the width b of the upper and lower borders 50A and 50B. The left and right borders 50
“V” is provided as a parameter for C and 50D. Furthermore, “Left”, “Rght”, “Top”, “Bt” are used as individual parameters of the borders 50A to 50D.
tm ". The border 50 can change the color as a whole, and its parameters are “Lum” for determining the lightness and “Sa” for determining the saturation.
t "and" Hue "for determining the hue. To set each parameter, an arrow cursor 51 is displayed on the menu by pressing the cursor switch 26, for example. As a result, each parameter can be set, the track ball 21 functions as a cursor moving unit, and the rotating ring 22 functions as a parameter setting unit. Now, in FIG. 8B, the parameter "Top" of the upper border 50A is set to 10.00 mm, whereby the width b of the upper border 50A is 10 mm.
Is displayed as To change this to, for example, 20 mm, the user rotates the trackball 21 to move the cursor 51 into the parameter display area 52. Thus, the value of the parameter “Top” 10.00 can be changed. When the rotating ring 22 is turned in this state, the value of the parameter sequentially increases or decreases.
When the operation of the rotary ring 22 is stopped at 0.00, and the cursor 51 is moved out of the range of the parameter display area 52, the value of the parameter “Top” becomes 20.00.
mm. With this, the width b of the upper border 50A is 2
Displayed at 0 mm. In this example, when the cursor 51 is within the parameter display area 52, the parameter value can be changed, and the cursor 51 is moved to the parameter display area 5
Although the parameter value is set when the user moves out of position 2, a separate switch (not shown), for example, is provided separately to operate the parameter so that the parameter can be changed or the value can be set. It is also possible to be performed. To operate a special image after setting the parameters in this way, the 3D input switch 27 is turned on. As a result, the trackball 21 and the rotating ring 22 become three-dimensional input means, and a special image on the image monitor 16 can be operated. FIG. 9 shows the procedure of the data input processing 60 in the three-dimensional video special effect device 1. In the data input processing 60, first, it is determined whether or not the operation mode of the trackball 21 is the cursor mode (step 6).
1). This determination is made by determining whether the cursor switch 26 is on. In the case of the cursor mode, next, the cursor 51 is displayed on the menu (step 62). Next, when the trackball 21 is operated, the amount of rotation is detected, and the cursor 51 is moved accordingly (step 63). Next, it is determined whether the cursor 51 has entered the parameter display area 52 (step 64). If not, the cursor 51 is moved in step 63 according to the amount of rotation of the trackball 21. When it is determined in step 64 that the cursor 51 has entered the parameter display area 52, the amount of rotation of the rotary ring 22 is detected, and the parameter value is changed accordingly (step 65). Next, it is determined whether or not the value of the parameter has changed (step 6).
6) If not, the amount of rotation of the trackball 21 is detected in step 63 and the cursor 51 is moved, and the same processing as described above is performed. If it is determined in step 66 that the parameter value has changed, then it is determined whether the cursor 51 is within the parameter display area 52 (step 6).
7). Here, the cursor 51 is moved to the parameter display area 5
If it is determined that it is within the range 2, the amount of rotation of the rotating ring 22 is detected in step 65, and the value of the parameter is changed. Thereafter, the same processing as described above is performed. When it is determined in step 67 that the cursor 51 has moved out of the parameter display area 52,
Thus, the value of the parameter is determined (step 68). Thus, one parameter is determined. Then, use cursor switch 2 to set another parameter.
6 is turned on as it is and it is determined in step 61 that the operation mode of the trackball 21 is the cursor mode,
Thereafter, the same processing as described above is performed. When the necessary parameter setting process is completed, the 3D input switch 27 is turned on. Now, it is not in the cursor mode in step 61,
That is, it is determined that the mode is the 3D input mode, and the 3D input process is performed by operating the trackball 21 and the rotating ring 22 (step 69). Thus, the data input processing 60 ends. As described above , according to the present invention, 3
