Abstract

PURPOSE:To prevent the influence of vibration applied to a specific data input means. CONSTITUTION:When a track ball 21 or rotary ring 22 for inputting three- dimensional data is rotated, its quantity of rotation is detected by counters 23, 24, and 25 and supplied to a CPU 11. At this time, when data other than the three-dimensional data are inputted by pressing, for example, a data input switch 28, it is also supplied to the CPU 11. In this case, a panel 2 vibrates by the shock generated when the data input switch 28 is pressed, and consequently it is judged that the track ball 21 or rotary ring 22 is rotated, so that the three-dimensional data are not supplied to a video special effect processing part 15. Therefore, even if vibration is applied to a data input means such as the track ball 21 and rotary ring 22, a special image is prevented from moving unnecessarily. Consequently, the track ball 21 and rotary ring 22 can be increased in sensitivity.

On the other hand, the trackball is supported so that it can be rotated with a light force in order to improve operability and sensitivity. Therefore, for example, when inputting data other than three-dimensional data with a numeric keypad or the like, vibrations are generated in the entire panel due to the impact when the numeric keypad is pressed, and this is transmitted to the trackball, and the trackball rotates. Dimensional data may be input. In this case, there arises a problem that the special effect of the image is disturbed.

Further, if the sensitivity of the trackball is made too sensitive, the influence of vibration becomes large, so that there is a problem that the sensitivity must be limited. Such a problem is 3
This is a problem common to not only the dimension input device but also various data input devices.

[0006] Therefore, the present invention has solved the above-mentioned problems and proposes a data input device capable of preventing the influence of vibration.

In order to solve the above problems, in the present invention, data input means for inputting data for inputting predetermined data, and vibration detection means for detecting vibration applied to the data input means. Data control means for controlling the output of the data input means by the output of the vibration detection means.

[0008]

In FIG. 1, when the trackball 21 or the rotary ring 22 for inputting three-dimensional data is rotated, the amount of rotation is detected by the counters 23, 24, 25, and this is supplied to the CPU 11. At this time, for example, when the data input switch 28 is pressed and data other than the three-dimensional data is input, this is also supplied to the CPU 11.

In this case, it is determined that the panel 2 vibrates due to the impact when the data input switch 28 is tapped, and the trackball 21 or the rotary ring 22 is thereby rotated, and the three-dimensional data is converted into the image special effect processing unit 15. Not supplied to. Therefore, even if vibration is applied to the data input means such as the trackball 21 and the rotary ring 22, it is possible to prevent the special image from being inadvertently moved.

As shown in FIG. 4, the rotating ring 22 is formed of a plate material having the same thickness in an annular shape, and an upper surface portion 22a and a flange portion 22b which are inclined in a conical shape are provided on the upper surface thereof. A step portion 22c is provided on the outer peripheral surface of the flange portion 22b. Further, as shown in FIG. 5, a large number of slits 22d having a predetermined width are provided at the lower end of the flange portion 22b at equal intervals over the entire circumference. This slit 22
d is disposed so as to cross the groove-shaped optical path portion 33a of the photo interrupter 33 attached to the base chassis 32.

As shown in FIG. 4, the rotating ring 22 is
The bearing 34 is disposed on the inner peripheral end surface of the upper surface portion 22a, and
A plurality of screw portions 22e are provided near the bearing 34 on the upper surface portion 22a, as shown in FIG. Then, one end of the retaining metal fitting 35 applied to the lower end surface of the bearing 34 is fixed by the screw portion 22e, whereby the rotating ring 22
Is fixed to the outer ring portion 34 a of the bearing 34.

Further, a fixed ring 36 is arranged on the inner peripheral surface of the rotary ring 22. The fixing ring 36 is supported by a stand pin 37 that is planted in the base chassis 32. The inner ring portion 34b of the bearing 34 is firmly fitted to the outer peripheral surface of the fixed ring 36 to fix the bearing 34. This makes it possible to rotate the rotary ring 22 in the circumferential direction, that is, in the direction corresponding to the Z axis with a light force.

On the other hand, the trackball 21 is the fixed ring 3
6, three cylindrical support rollers 3 arranged on the inner peripheral side of the base 6 and mounted on the base chassis 32 as shown in FIG.
It is supported by three points at 8, 39 and 40. Then, as shown in FIG. 6, the upper side of the trackball 21 is the fixing ring 3
It projects from the upper end surface of 6 in a dome shape, and this projecting portion can be operated from the outside.

The cylindrical support rollers 38, 39, 40 are rotatably supported at their central axes 41, and one of the support rollers 38 is arranged at a right angle to the X direction in FIG. Has been done. Another support roller 39
Are arranged at right angles to the Y direction orthogonal to the X direction. Therefore, when the track ball 21 is operated by a finger to rotate, the support rollers 38 and 39 also rotate according to the amount of rotation.

Next, the trackball 21 and the rotating ring 2
A method of detecting the rotation amount of 2 will be described. Rotating ring 2
As described above, the photo interrupter 33 is used to detect the rotation of 2, that is, the rotation in the Z direction. In the photo interrupter 33, as shown in FIG. 4, the light emitting element and the light receiving element are arranged on the printed board 31 so as to face each other so as to form a groove-shaped optical path portion 33a.

The rotary ring 22 rotates to rotate the slit 22d.
When the light beam crosses the optical path portion 33a, the photo interrupter 33 outputs a pulsed electric signal. This pulse number is Z
The amount of rotation of the rotary ring 22 can be detected by counting with the 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 4. These photo interrupters 42 and 43 are configured similarly to the above-mentioned photo interrupter 33, and the light emitting element and the light receiving element are arranged so as to face each other so as to form the optical path portions 42a and 43a as shown in FIG.

When the cylindrical support rollers 38, 39 rotate, the radial slits 44a of the disc-shaped shutter plate 44 attached thereto cross the optical path portions 42a, 43a to output a pulsed electric signal. , This is X
By counting with the counter 23 or the Y counter 24, the amount of rotation of the trackball 21 in the X direction or the Y direction can be detected.

As shown in FIG. 1, the outputs of the X counter 23, the Y counter 24, and the Z counter 25 are transferred to the C via the bus 12.
It is taken into PU11. Then, as described above, the CPU
The image special effect processing unit 15 is controlled by the instruction 11 to operate the special image on the image monitor 16 in the three-dimensional direction.

When operating the special image, the 3D input switch 27 is turned on. This is trackball 2
It becomes possible to input three-dimensional data from the 1 and rotating ring 22, and by rotating these, it is possible to operate a special image.

It is assumed that the trackball 21 or the rotary ring 22 is rotated by a shock of strongly hitting the data input switch 28 when the trackball 21 or the rotary ring 22 is not operated. In this case, the amount of rotation of the trackball 21 or the rotating ring 22 depends on the counter 23,
24, 25 detected count values X1, Y1, Z1
Is supplied to the CPU 11. At this time, the data input by the data input switch 28 is also supplied to the CPU 11.

When the three-dimensional data output from any one of the counters 23, 24, and 25 and the other data are supplied to the CPU 11 as described above, the trackball 21 is pressed by the data input switch 28 or the like. Alternatively, it is determined that three-dimensional data has been input due to vibration applied to the rotary ring 22, and the outputs of the counters 23, 24, 25 are not supplied to the video special effect processing unit 15. This prevents the special video from moving carelessly.

In this example, each counter 23, 24, 2
Although the output of the three-dimensional data from 5 is limited by software, it is also possible to limit the output of the three-dimensional data by using a changeover switch (not shown). In this case, the changeover switch may be turned off only while data other than the three-dimensional data is being input so that the three-dimensional data is not output.

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. 8A. Is created by the graphic display creating unit 14 as described above, and this is displayed on the menu monitor 17 as various menus. FIG. 1B shows an example of a menu display for border setting.

In this menu, the width b of the entire border 50 is
“All” is provided as a parameter for determining the value of “B”, and “H” is provided as a parameter of the width b of the upper and lower borders 50A and 50B. Also, the left and right borders 50
“V” is provided as a parameter for C and 50D. Furthermore, “Left”, “Rght”, “Top”, and “Bt” are set as individual parameters of the respective borders 50A to 50D.
tm ”is provided. Further, the border 50 can change the color as a whole, and as its parameters, “Lum” that determines the lightness and “Sa” that determines the saturation degree.
“T” and “Hue” that determines the hue are provided.

When setting each parameter, the cursor switch 26 is pressed to display, for example, an arrow-shaped cursor 51 on the menu. As a result, each parameter can be set, the trackball 21 serves as the cursor moving means, and the rotary ring 22 serves as the parameter setting means.

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 displayed as 10 mm. To change this to 20 mm, for example, the trackball 21 is turned to move the cursor 51 into the parameter display area 52. Now, the value 10.00 of the parameter “Top” can be changed.

When the rotary ring 22 is rotated in this state, the value of the parameter increases or decreases in sequence, so this value becomes 2
When the value of 0.00 is reached, the operation of the rotary ring 22 is stopped, and if the cursor 51 is moved outside the range of the parameter display area 52, the value of the parameter “Top” becomes 20.00.
set to mm. The width b of the upper border 50A is now 2
It is displayed as 0 mm.

For example, when the rotating ring 22 is rotated by vibration, the parameter values are changed carelessly.
In the three-dimensional image special effect device 1, each counter 23, 24, 2
When the data from 5 and the data from other parts are simultaneously input, the rotary ring 22 or the trackball 21
Is determined to have rotated due to vibration, and each counter 23, 2
The data from 4 and 25 are not supplied to the graphic display creating unit 14, so that the influence of vibration can be prevented.

When the special image is operated after setting the respective parameters in this way, the 3D input switch 27 is turned on. With this, the trackball 21 and the rotary ring 22 become a three-dimensional input means, and the special image on the image monitor 16 can be operated.

FIG. 9 shows the procedure of the three-dimensional data output processing 60 in the three-dimensional image special effect apparatus 1. In this three-dimensional data output processing 60, the three-dimensional data X1,
When Y1 and Z1 are input (step 61), the current coordinate data X0, Y0,
Z0 is placed (step 62). Next, it is determined whether or not data other than three-dimensional data has been input (step 63). That is, here, the data input switch 28
The panel 2 vibrates by hitting a key, and the trackball 21 or the rotary ring 22 is rotated by this, and it is determined whether or not three-dimensional data is input.

If it is judged in step 63 that data other than the three-dimensional data is input, then the system waits for t seconds, for example, several tens of ms (step 64), and then output data X, Y, Z is output ( Step 65), whereby the three-dimensional data processing 60 ends. In this case, the special image does not move.

If it is determined in step 63 that the data other than the three-dimensional data is not input, the coordinate data X0, Y0, Z0 of the special image and the three-dimensional data X1, Y1, Z1 input are added. Output data X, Y, Z
(Step 66), which is step 65
And the three-dimensional data output process 60 ends. In this case, the special image is moved by the input three-dimensional data.

In this embodiment, since all the vibrations are detected by software as described above, it is possible to prevent the influence of vibrations without adding other parts to the conventional three-dimensional input device. As the vibration detection method, various detection methods can be used, for example, the vibration of the panel 2 is directly detected by the acceleration sensor, or the vibration is detected by detecting the sound of the panel 2 hit by the voice microphone. Is.

Although the case where the trackball 21 and the rotary ring 22 are used as the three-dimensional data input means has been described, the present invention can be applied to a three-dimensional input device having a joystick or other data input means. Is.

[0043]

As described above, the present invention is, for example, 3
When predetermined data such as dimension data is input, it is detected whether or not vibration is applied to the input means, and when vibration is applied, the input predetermined data is not output.

Therefore, according to the present invention, it is possible to prevent the special image and the value of the parameter from being inadvertently changed by the vibration, and to make the sensitivity of the data input means such as the trackball and the rotating ring more sensitive than before. There is an effect that it becomes possible.
