There is disclosed a technique in which an operation member is provided to output to the operation state determination means, and the shake correction characteristic is adjusted by the operation member while observing the output level of the video signal.

[0004]

In the case of a game image display device such as an arcade game, there is a device that causes a shake in an image projected to increase the fun and power of the game. If the degree of this swing is large,
Some people feel sick. This state is called simulator thickness.

[0005] In the above-mentioned conventional technique, it is possible to suppress the shake of the image apparatus itself and to suppress the fluctuation of the projected image, but it is necessary to maintain the fun and power of the image that the user experiences as much as possible and to reduce the shake. No attempt has been made to suppress it.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a user-friendly image apparatus which overcomes the above-mentioned problems of the prior art, suppresses the occurrence of simulator sickness, and provides a user-friendly image apparatus.

[0007]

According to the present invention, there is provided a display device, a mounting table with a vibrating device for mounting the display device, a vibration driving device for applying vibration to the mounting table, and controlling the vibration driving device. The control device comprises a control device, the control device detects a motion of an image projected on a display device, generates a control signal for suppressing the motion, and supplies the control signal to the vibration driving device to drive the mounting table. It is a video device.

Further, there is provided a level adjusting means capable of adjusting a control signal for suppressing the movement according to the detected movement by a user. Further, it is desirable that the mounting table with the vibration device is formed of a table section on which the display device is mounted and a vibrating leg section supporting the table section.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the video apparatus of the present invention is applied to an arcade game machine will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing an overview of an image apparatus, and FIG.
FIG. 1 is a perspective view showing an overview of an arcade game machine containing a video device. In FIG. 1, reference numeral 1 denotes a display device such as a liquid crystal projector, 2 denotes a mounting table on which the display device 1 is mounted and a vibrating device 3 is provided, and 4 denotes a display for adjusting the vertical and horizontal inclination of the screen of the display device 1. A driving device 5 for driving the vibration device is a control device for supplying the drive device with information on an appropriate vibration amount to the vibration device 3.

FIG. 2 is a schematic view of an arcade game machine (flight simulator) accommodating the video device, and a display unit 1 having a screen display window 12 formed on a front surface of a main body 11.
3, and a projection screen 14 is arranged in the window 12.

Reference numeral 15 denotes an operation handle, which is a member for allowing a user to move an object constituting the game displayed on the screen. Reference numeral 16 denotes a chair on which the user sits during the game. A box-shaped level control device 17 is provided on the side of the chair, and large, medium, small, and OFF operations for setting the adjustment level of the vibrating device 3 on the upper surface of the level control device 17 according to the user's preference. Buttons 18 to 21 are attached.

Next, the position adjustment of the display screen by the vibrating device 3 will be described with reference to the circuit block diagram of FIG. 3 and the image display example of FIG. An image output from a video playback device 31 such as a CD, VTR, or LD is input to the display device 1 and displayed on a screen as a video.

On the other hand, the image is inputted to the motion detecting means 32 in the control device 5, where the data of the current frame and the image of the previous frame are compared, and the data such as the presence or absence of motion, its direction and amplitude are obtained. Is calculated.

The data of the motion (vibration) of the image calculated in this manner is then transmitted to the drive control means 3 in the same control device 5.
3 to the driving device 4 where the vibration device 3
Is generated to generate a drive signal for driving so as to suppress the shake.

Reference numeral 35 denotes level setting means. This input is used for adjusting the degree of vibration suppression by the operator pressing his / her favorite button using the operation buttons 18 to 21 of the level control device 17. The information on the pressed button is converted into a correction signal by the level setting means 35, and the correction signal is supplied to the correction means 34 in the control device 5.

The correcting means 34 comprises the level setting means 3
The drive signal is corrected based on the correction signal from 5, and the corrected drive signal is sent to the drive device 4. The driving device 4 transmits an information signal such as the amount of vibration and the direction to the vibration device 3, and in response thereto, the vibration device 3 vibrates the mounting table 2 with the vibration amount according to the preference of the operator. Then, the shake image is subjected to a desired correction to create an image with reduced shake, and this is projected on the screen 14 via the display device 1 and projected.

The vibrating device 3 has four legs that can be independently controlled, and is configured to finely adjust the lengths of the legs to adjust the runout. For adjusting these lengths, a ball screw device or the like driven to rotate by a motor is used.

For the level selection of the level setting means, for example, when the operator is extremely strong in the simulator sickness and feels that it is more realistic to shake the screen considerably, the OFF operation button 21 is selected. Become.

An operator who is apt to get drunk on a vehicle gets drunk when the screen shakes sharply. Therefore, it is necessary to increase the suppression of the shake, and the large operation button 18 is selected.

The level between these levels may be appropriately adjusted according to the preference of the operator. The adjustment of the shake will be described. For example, when the screen swings and tilts as shown in FIG. 4A as shown in FIG. 4, this movement is detected by the extended motion detecting means, and as shown in FIG. I will return to the state.

This return is performed by using the operation buttons 18 to 2 described above.
Depending on the selection of 1, the image during rotation between (A) and (B) is extracted by the button, and the degree of shake suppression can be adjusted. Of course, if an analog operation means such as a volume is used instead of the operation button, it is needless to say that the adjustment of the shake can be changed not in discrete values but in an analog manner.

[0023]

As described above, the present invention provides a display device, a mounting table with a vibrating device for mounting the display device, a vibration driving device for applying vibration to the mounting table, and the vibration driving device. The control device generates a control signal for suppressing the motion by detecting the motion of the image projected on the display device, and supplies the control signal to the vibration driving device to mount the control signal. By driving the table, protection against simulator sickness can be performed according to individual differences between operators, and the effect of suppressing the occurrence of simulator sickness and providing a user-friendly video device is expected. it can.
