DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus for reproducing music for singing, a communication karaoke apparatus, and an image display apparatus in a personal computer and the like.

[0002]

2. Description of the Related Art Conventionally, various types of performance music (referred to as "karaoke songs") for a user to sing from a microphone are reproduced, and a plurality of still images are displayed on a screen of a display device at predetermined time intervals in accordance with the karaoke songs. Karaoke device that switches and displays
JP-A-60-214178). However, in such a karaoke apparatus, there is a problem that the image displayed on the screen changes only to a still image, and the singer or the viewer tends to get bored.

Therefore, a video reproducing apparatus such as a player or a changer for reproducing an optical disk such as a CD or LD is connected to the outside, and a CD, L or the like is displayed on the screen of the display device in accordance with the karaoke music.
There is provided a karaoke apparatus for reproducing and displaying a moving image based on moving image data recorded on an optical disk such as D.

The changer used in the karaoke apparatus as described above can be mounted by inserting a plurality of optical discs from the outside. When reproducing a karaoke song, one of the optical discs is selected according to the karaoke song. Is a device for reproducing moving image data corresponding to a karaoke song recorded on the optical disk.

[0005] As described above, when a moving image is displayed as a background image when singing a karaoke song, the content of the display becomes rich and a karaoke environment in which a singer and a viewer can enjoy singing can be provided.

[0006]

However, the karaoke apparatus which can display a moving image by using the above-described video reproducing apparatus has the following problems.

(1) In addition to the karaoke apparatus, it is necessary to purchase a video reproducing apparatus, and the initial investment becomes expensive. In particular,
The price of changers was so high that individuals and small shop owners could not easily buy them.

(2) When a video reproducing apparatus is connected to the outside of the karaoke apparatus, the occupied area of the entire apparatus increases, and the apparatus cannot be used in a place where installation space is limited. For example,
In a room such as a room of a general household, a small snack, or a karaoke box having a small space in one room, a limited space is occupied by the apparatus, so that a comfortable singing environment cannot be provided to the user.

(3) An optical disk can be attached to and detached from the video reproducing apparatus. By replacing the optical disk, a new moving image corresponding to a new karaoke song can be reproduced. In addition, foreign substances easily enter the inside of the apparatus, and these foreign substances adhere to a mechanism for rotating and driving the optical disk or a mechanism of an optical system for reading moving image data from a recording surface of the optical disk, and thus a failure is likely to occur.

[0010] In particular, in a store where the above-mentioned karaoke apparatus is installed, there is a lot of fine garbage and dust in the installation place, and purple smoke is smoked by a user smoking.
Since there is much moisture near the water, the foreign matter frequently causes the video reproducing apparatus to malfunction and become unusable, resulting in a serious problem that the service to the user is deteriorated.

(4) When the video reproducing apparatus is tilted or vibrated, the internal optical disk may be displaced from a predetermined mounting position. If the optical disk is reproduced while being deviated from the predetermined mounting position, an optical system The mechanical part contacts the recording surface and damages the optical disk, and the display of the moving image is suddenly stopped at the time of singing, giving the user discomfort.

For example, in a facility such as a hotel or a ryokan where the above-mentioned karaoke apparatus is used for a banquet, the karaoke apparatus is tilted or vibrated when the karaoke apparatus is carried into a hall, so that the internal optical disc is shifted. In many cases, the reproduction was started immediately and a sudden failure occurred. As a result, there has been a serious problem that the atmosphere at the banquet is greatly impaired.

(5) When the above-described karaoke apparatus is installed in a vehicle or the like and used, the same problem as described above has occurred due to vibration during the running of the vehicle. Therefore, if the background video at the time of singing cannot be displayed normally due to the causes described in the above (3) to (5), the service for the user will be significantly reduced, and the karaoke apparatus management company will be in trouble However, there is a problem that a large amount of cost is required for maintenance work such as recovery work.

(6) The amount of moving image data is large, and the amount of moving image data for reproducing a moving image for one song is extremely large. As a result, the types of moving images that can be recorded on one optical disk are reduced, and in order to provide moving images for various karaoke songs, many optical disks must be prepared, which increases the cost for the user.

Therefore, if the amount of moving image data for one song is reduced to increase the types of moving image data to be recorded on one optical disc, the reproduction time is shortened or the image quality deteriorates. Can not provide comfortable images.

(7) The mastering operation of recording moving image data on an optical disk takes time, and a new moving image corresponding to a new song cannot be used quickly. In addition, since it is costly to create an optical disk for a moving image for each song, the user cannot use the moving image at the time of singing at low cost. Furthermore, the user could not enjoy singing with the original background video.

As described above, the video reproducing apparatus is expensive,
There is also a problem in that an extra installation space is required, failures are likely to occur unless the user pays attention to the latest, and a moving image service using an optical disc cannot be used easily at low cost by a user.

The present invention has been made in view of the above points, and is an expensive and trouble-prone player for reproducing a moving image recorded on an optical disk so that a variety of images can be displayed using a still image. It is an object of the present invention to provide an environment in which a user can enjoy a variety of images at a low cost without a risk of becoming unusable due to a failure without using an image reproducing device such as a camera or a changer.

(Horizontal direction) (indicated by an arrow A in the figure). For example, the selection number of the still image data 30 is set as the “image selection number” in the video control information, the coordinate value of the display area 31 is set as the “position information”,
The XY offset value in the horizontal right direction of the screen shown in FIG. 12 is set in the “movement direction / movement amount”, and a predetermined frame time unit value is set in the “movement time”. If the area 31 is moved to the position of the display area 31a after being moved to the position of the display area 31a, an image moving rightward with respect to the screen can be displayed.

Further, as shown in FIG.
To the vertical direction (vertical direction, vertical direction) on the still image data 30
(Arrow B in the figure). For example, the selection number of the still image data 30 is set to “image selection number” in the video control information,
In the “position information”, the coordinate value of the display area 32 is set to “moving direction /
The display area 32 is displayed by setting the XY offset value in the vertical downward direction of the screen shown in FIG. 12 in “movement amount” and a predetermined frame time unit value in “movement time” and executing the movement processing. If the image is moved to the position of the display area 32b after being moved to the position of the area 32a, an image that moves downward with respect to the screen can be displayed.

Further, as shown in FIG.
3 is moved diagonally on the still image data 30 (arrow C in the figure). For example, the selection number of the still image data 30 in the “image selection number” in the video control information, the coordinate value of the display area 33 in the “position information”, and FIG.
The XY offset value in the screen diagonal right direction shown in FIG. 2 and a predetermined frame time unit value are set in the “moving time”, and the moving process is executed.
3 is moved to the position of the display area 33a.
By moving to the position 3b, it is possible to display an image that moves diagonally downward and rightward on the screen.

Further, as shown in FIG.
Is moved on the still image data 30 so as to draw a curve (arrow D in the figure). For example, the selection number of the still image data 30 is shown in “image selection number” of the head element of the video control information, the coordinate value of the display area 34 is shown in “position information”, and FIG. 11 is shown in “moving direction / movement amount”. An XY offset value in the diagonal right direction of the screen is set, and a predetermined frame time unit value is set as the “movement time”.

Further, by continuing the contents of the “position information”, the “XY” in the screen diagonal direction (in this case, the screen diagonal right direction) shown in FIG.
A value different from the offset value and a predetermined frame time unit value are set for the “movement time”.

By setting the above two elements and executing the movement processing, the display area 34 is displayed.
If the image is further moved to the position of the display area 34b after being moved to the position a, it is possible to display an image that moves so as to draw a curved line diagonally upward and to the right with respect to the screen.

Further, if a plurality of the above directions are combined, a moving image with more variety can be displayed. For example, as shown in FIG. 17, after moving the display area 35 in the horizontal direction (horizontal direction, horizontal direction) on the still image data 30, the display area is moved up and down (vertical direction, vertical direction) on the still image data 30. ) Is repeated (arrow E in the figure).

For example, as shown in FIG. 18, the selection number of the still image data 30 is set as the “image selection number” of the head element of the video control information, the coordinate value of the display area 35 is set as the “position information”,
The XY offset value in the horizontal right direction of the screen shown in FIG. 12 is set in “moving direction / movement amount”, and a predetermined frame time unit value corresponding to 5 seconds is set in “moving time”.

Further, by continuing the content of the “position information”, the XY offset value in the downward direction of the screen shown in FIG. 11 is added to the “moving direction / movement amount” of the next second element, and the “moving time” , A predetermined frame time unit value corresponding to 3 seconds is set. Similarly, an XY offset value in the right direction of the screen is set in the “movement direction / movement amount” of the third element, and an XY offset value in the lower direction of the screen is set in the fourth element.

By setting the above four elements and executing the movement processing, the display area 35 is moved rightward by 5 seconds with respect to the screen and moved to the position of the display area 35a. After moving down to the position of the display area 35b by moving down for 3 seconds, moving rightward for 5 seconds with respect to the screen and moving to the position of the display area 35c, moving down to the image for 3 seconds and displaying the image By moving to the position of the area 35d, a moving image in which the moving direction is changed stepwise with respect to the screen can be displayed.

Although not shown, if the still image data is rotated around a predetermined position (for example, the center) of the display area, a more varied moving image can be displayed. it can.

FIG. 19 is a flowchart showing the process of moving the display area for still image data in the karaoke apparatus. "S" in the figure indicates each step in this processing. Note that the timer referred to by the image processing unit 105 is activated by an interruption of vertical blanking of the screen, and integrates a current start time, a current movement time, and the like.

The karaoke apparatus stores the video control information sent from the CPU 101 in the rewritable RAM 103 at each switching timing of the still image indicated by the processing type of the synchronization control data in accordance with the progress of the music to be played, This video control information is referred to under the image processing unit 105 (S2
1).

Next, based on the tempo classification indicated in the genre of the karaoke song, the moving time is maintained, and a change is made with a value based on one of three divisions of addition or subtraction in predetermined frame time units ( S22). Then, after the current start time of the timer is initialized to "0" (S23), the first element of the video control information is extracted (S24). Thereafter, the current start time of the timer is compared with the execution start time of the scene for which the set is set (S25), and if they are equal, it is determined whether or not the element number of the previous scene exists in the element link (S26). , To S29.

Further, when it is determined in S26 that the contents of the previous scene are taken over after the completion notification is sent to the subroutine executing the contents of the set previous scene (S27), The position coordinate value of the still image data updated in the step is set as the position information of the element to be executed (S2).
8).

Then, the contents of the scene of the element to be executed are interpreted, and the display area moving processing subroutine for the specified still image data corresponding to each scene is executed (S
29). In this embodiment, the case of the moving image display processing based on the still image has been described, but other display processing such as wipe and dissolve may be added.

Next, when there is an instruction from the CPU 101 to end the performance or to switch the still image data (S30), the processing ends with the subroutine being executed. In this way, restart is performed at the timing of switching the still image data.

Further, after the execution of one element, the presence or absence of the next element is determined (S31). If there is, the next element to be executed is extracted (S32), and the process proceeds to S25. If not, the process proceeds to S30. Thus, the process is repeated until the end of the performance or the instruction to switch the still image is issued.

FIG. 20 is a flowchart showing a subroutine process for moving the display area for still image data such as landscape having a size larger than the screen. This subroutine process is started by the image processing unit 105 based on the video control information. "S" in the figure indicates each step in this processing.

In this process, after the current movement time of the timer is initialized to "0" (S41), the still image data is read out with reference to the image selection information, developed in the display memory 30 (S42), and the position is read. The display area G of the screen size of the display device 22 on the still image data is set from the coordinate values indicated in the information (S
43).

Further, the current moving time of the timer is compared with the moving time (S44), and when they are not equal, the flow proceeds to S47. If the comparison results in S44 are equal, the display area G is set based on the movement direction and the movement amount in the movement information (S45). With this setting, the display area G moves in a predetermined direction. Proceeding to the next step, the content of the position information is updated with the coordinate value of the moved display area G, and the current travel time is initialized (S46).

Then, it is determined whether or not there is a notification of the end of the process from the image processing unit 105 which has activated this subroutine (S47), and if there is, the process is terminated. This means that the designation of the movement change of the new display area for continuing the position coordinates at the end point has occurred.

[0115] If it does not exist in the judgment of S47,
Returning to S44, the above-described processing is repeated until the end notification is received. In this subroutine processing, the information of each element of the video control information is specified in a time series, so that the display area G
Can be continuously or intermittently moved in a specified moving direction at a specified moving time.

In this process, before the end of the display area G on the moving direction side reaches the end of the still image data 30, switching is performed in the opposite direction to repeat the moving process, or the moving process is started again from the first position. The movement information in each element of the video control information may be set so as to be repeated or moved in another direction, and such processing is repeated until the timing of switching the still image data or the end of the music piece is notified. .

If the moving time and the moving amount are specified to be small, the image on the screen can be smoothly moved and displayed at a constant speed. Further, if the moving time is increased or decreased according to the tempo change of the performance music or the tempo classification indicated in the genre, the moving speed can be changed, and a moving image with more changes is displayed. be able to.

Further, the timing of switching the still image data may include, for example, performance information such as when a preset time has elapsed, when a predetermined phrase of lyrics has ended, or when the tempo of the music has changed. It can be set correspondingly.

In this karaoke apparatus, if the video control information is stored in the storage device 24 in association with music data or still image data, a moving image display corresponding to the contents of the music data or still image data can be performed. I can do it.

Also, a plurality of types of still image data are made to correspond to one piece of music data, and the still image data is switched as the performance music progresses, whereby a plurality of types of moving images can be displayed in one performance music. You.

Further, if still image data including various scenes in one piece of music data is used, an image having a story characteristic to the performance music can be displayed on the screen by the above-described display area moving processing. it can.

In this embodiment, each piece of information in the video control information is created in association with music data or still picture data, and the selection information of the still picture data, the moving direction / movement amount information of the image, and the moving time. Although the case where the information and the like are determined in advance has been described, for example, if a registration mode and an edit mode are provided, registration of video control information by adding or deleting still image data to and from the storage device 24, and Editing of each information can be performed.

In the registration mode, for example, an image is read from a storage medium such as a floppy disk or a flash memory in which a user individually stores still image data shot by a device such as a digital camera or still image data prepared by a manufacturer. The image data is read through the device, stored in the storage device 24, and the video control information is newly registered in the control information management table.

Alternatively, the ISDN is sent from the host device of the center.
Still image data distributed to the karaoke apparatus via the public line network such as the above may be stored in the storage device 24, and video control information may be newly registered in the control information management table in the same manner as described above.

On the other hand, in the edit mode, for example, the user inputs a control selection number from the input device 107 or the keyboard of the remote control device and reads out the corresponding still image data.
Using the keys corresponding to the selection of the moving direction of the image and the adjustment of the moving time as shown in FIG. 23 to be described later, editing each information in the video control information while visually recognizing the screen of the image being reproduced. Can also.

FIG. 21 shows the video control information registration unit 110
9 is a flowchart showing a process of registering video control information by adding still image data in FIG. "S" in the figure indicates each step in this processing. FIG. 22 is a flowchart showing the editing processing of the video control information in the video control information registration unit 110. "S" in the figure indicates each step in this processing. FIGS. 23A and 23B are diagrams illustrating an example of key assignment information of the remote controller corresponding to switching of the moving direction of the image and adjustment of the moving time.

First, the registration processing of the video control information will be described with reference to the flowchart of FIG. When the user selects the registration mode from the keyboard of the remote control device, the mode shifts to the registration mode, the storage medium on which the still image data is recorded is read via the reading device (S61), and the still image data is identified for identification. The still image data number is added and stored in the storage device 24 (S62). Thereafter, it is determined whether there is still image data to be read (S63), and if there is still image data to be read, the process proceeds to S61,
If not, the process proceeds to S64.

Further, it is determined whether or not a new key is input from the remote controller (S64). When the new key is input, when a predetermined number of still image data numbers are input in the order of reproduction, the control information A predetermined number of pieces of video control information are generated in a new element of the management table (S65). Thus, one or a plurality of pieces of video control information corresponding to the new control selection number are sequentially registered.

On the other hand, when the end key is input in the judgment of S64, the process ends without generating video control information in the control information management table.

Next, the editing process of the video control information will be described with reference to the flowchart of FIG. When the user selects the edit mode from the keyboard of the remote control device, the mode shifts to the edit mode. When the control selection number is input (S70), the control information management table is searched based on the input control selection number. Then, the reproduction simulation of the still image data is started with reference to the first still image data number from the corresponding element of the control information table (S7).
1).

If no value is set for the moving direction, moving amount, moving time, etc. in the video control information, for example, the position information is set to coordinate values at the horizontal left end and vertical upper end, and the center is moved. The direction / movement amount is set to one dot unit in the horizontal right direction, and the standard value is used by setting the movement time to 3 frame time units (S72), and the process proceeds to S73.

When the user recognizes a key input corresponding to the key assignment information shown in FIG. 23 from the remote controller while visually recognizing the screen of the still image data being reproduced, the moving direction and moving of the temporary video control information are recognized. Each data of time is sequentially changed (S73). Thereafter, when a preset still image switching time is reached, the next video control information is referred to (S74), and the presence or absence of video control information is determined (S75).
If there is, the still image data specified in the video control information is read out, and the flow shifts to S72.

On the other hand, if it is determined in S75 that there is no video control information and the display is empty, and the enter key is input from the remote controller (S76), the contents of the temporary video control information are updated to the official video control information. (S77), the process ends by inputting the end key. If the end key is input without the enter key being determined in S76, the process ends without updating the video control information.

In this way, prior to the reproduction of the performance music, still image data such as an arbitrary photograph or screen is fetched from the image reading device or the host device of the storage medium into the storage device 24.
By registering new video control information in the control information management table and editing the video control information for the obtained still image data, a moving display image based on the still image data selected by the user can be quickly reproduced. it can.

The still image data switching time is defined as
By setting the execution start time in the video control information and editing the video control information, the original still image data for each user can be set to any timing regardless of the timing of switching the still image data in the music data Can be played back by switching.

Further, the user can arbitrarily change the data such as the moving direction, the moving amount, and the moving time of the video information by using the keyboard of the remote control device during the reproduction of the music.

As described above, the karaoke apparatus of this embodiment has the following effects.

And a comfortable singing environment can be provided to the user at the banquet.

Further, even when the karaoke apparatus is installed in a vehicle or the like and used, a normal image can be displayed even by a slight vibration when the vehicle travels, and it is possible to flexibly cope with various use modes by the user. can do. And
By almost eliminating the occurrence of failures as described above,
For the management company that performs the maintenance of the karaoke apparatus, it is possible to greatly reduce the cost of the recovery work in the event of a failure.

(5) Since still image data has a smaller capacity than moving image data, a very large number of types of data can be stored and used in a storage device having a limited capacity, and the number of image types is increased. Requires less space than video data, and eliminates the need to increase storage space as the number of optical disks increases, thus providing users with a variety of images at low cost. it can.

(6) The resolution of still image data can be increased with a smaller data amount than that of moving image data, and a high quality image can be easily provided to the user.

(7) Still image data can be easily added or rewritten to the storage device, so that a new image corresponding to a new song can be provided quickly. If the user registers the original still image data, The user can enjoy singing with the original background video for each user, and can provide a variety of various background images for karaoke songs.

The moving image display processing based on a still image according to the present invention can be performed by a communication karaoke apparatus capable of distributing karaoke music data from a center host apparatus via a public line network such as ISDN, PSTN, or the like. The present invention can also be applied to a personal computer capable of reproducing performance music for singing based on data.

If still image data is distributed from the host device to the karaoke device via the public line network, various types of data can be transmitted in a shorter time than when moving image data is transmitted. In addition, a plurality of types of still image data corresponding to the music data can be quickly delivered together with the music data of the new music, and a variety of image display services can be provided at low cost when performing music.

[0149] Further, the creation of moving image data requires a lot of trouble, but still image data can be easily created and edited by a user. Many types of data can be stored in a small-capacity storage medium such as a memory.

Therefore, the above-mentioned karaoke apparatus is provided with a function of reading the above-mentioned storage medium, or a function of connecting an image reading apparatus such as a scanner to read an image such as an arbitrary photograph or drawing and inputting the still image data. With such a configuration, the user can easily import the self-made and arbitrarily prepared still image data into the karaoke apparatus. Therefore, it is possible to enjoy a variety of image displays in accordance with the music played by the karaoke device and the TPO at the time of singing, and it is possible to further enhance the entertainment when the karaoke device is used.

[0151]

As described above, according to the image display apparatus of the present invention, by displaying a variety of images using a still image, an expensive moving image recorded on an optical disk can be reproduced.
