[Industrial applications]

 The present invention relates to a music information display device for displaying a disc label in an LD / CD player. Here, the song display device is a device for displaying playing songs used in audiovisual equipment such as a karaoke device, and is a song information display device applicable not only to these devices but also to other information communication devices.

[0002]

[Prior Art]

 Conventionally, in audiovisual equipment such as karaoke, to select a performance song in advance, select the song from the song list and play the song by remote-controlling the song number or pressing the control switch. There is. Also, song information is stored for each disc, each disc is displayed on the monitor at any time, and selected from the song information in the disc, the played song is played, and not only CD / LD but also TV or tuner. There are also custom files used for. Furthermore, in Japanese Patent Laid-Open No. 61-16684, the music information corresponding to the bar code is displayed on the TV screen, and the corresponding bar code on the TV screen is input using a light pen to obtain the identification information corresponding to the bar code. It is disclosed that a song is searched, the song is selected from the displayed song information, and the song is input to the player to start playing the song. Further, Japanese Patent Application Laid-Open No. 59-180867 discloses a method of reading disc label information of a disc with an image sensor while rotating the disc, displaying the information on an image display device, and storing the information in a memory.

[0003]

[Problems to be solved by the device]

 However, it is troublesome if you do not have the choice of songs while looking at the jacket. Furthermore, in the custom file, the operator has to register the music information by a predetermined symbol or abbreviated symbol according to the number of the music stored on the disc, which is a troublesome work. With the light pen input, you must move to the TV screen with the light pen after the performance of the song is completed. Even when the disc is rotated and the disc level is read, no information is displayed unless the image sensor rotates after inserting the disc. As a result, the waiting time between songs becomes long, and in order to capture the information correctly, a marker must be placed on the disc to mark the starting point of reading the stored information, which is a troublesome task. The present invention has been made to solve these problems.

[0004]

[Means for Solving the Problems]

 A writing device that scans the song information displayed on the surface of the plate-shaped storage medium when the medium is mounted and moved to perform analog / digital conversion of the captured video symbol, and writes the stored content if necessary. It is a music information display device including an image amplification device for extracting and digital-analog converting and amplifying the image.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic view of a laser disk for karaoke according to the present invention. A disc label is attached to the front surface, and the titles and numbers of the songs stored in the disc memory are displayed. FIG. 2 is an explanatory view showing an image pickup device for reading the music piece information stored at the disc level. In the present invention, an image sensor or a CCD camera can be used as the image pickup device, but the image pickup device is not limited to this. In FIG. 2, the disc (1) is placed on the pallet (2) and housed in the disc player (3). In this case, be sure to insert the disc in the correct direction so that the title of the disc is in the insertion direction. On the other hand, the image pickup device (4) is mounted in the disc player (3), and when the disc (1) is placed on the pallet (2) and moved into the disc player (3), inside the center portion of the disc (1). The track information stored in the disc label (5) on the circumference is scanned.

FIG. 3 is a block diagram showing a process in which the image pickup device scans the disc label. In the figure, the drive output according to the command from the control device (6) drives the image pickup device (7), and displays the curved surface information of the disc label (5) which is placed on the pallet (2) and inserted and moved into the disc player (3). To scan. The music information read by the image pickup device (7) is converted from analog to digital by an analog / digital converter (8) and written in a writing device (9) by a write control signal from a controller (6). The musical piece information written in the digital memory is output by a switching signal from the control device (6), the information is expanded and integrated, and then sent to the expansion device (10). Subsequently, the expanded song information is digital-to-analog converted by the digital / analog converter (11) and switched to a video signal by the video amplifier (12). As shown in FIG. It is enlarged and displayed on the TV screen. At this time, a normal image is cut off by a switch signal from the control device (6).

FIG. 5 is a flowchart showing a process in which the image pickup device in the disc player operates and the image pickup device scans the disc label. Use the remote control switch to set the disk player to the start state. When the pallet (2) is in the open state (S1), the disc (1) is placed and the pallet (2) is closed (S2). If the pallet (2) is not open, place it in the open state before placing the disc (1). When the pallet (2) enters the inside of the disc player (3), it receives the drive output from the control device (6) and drives the photographing device (7) (S3). When the image pickup device (7) reads the music information of the disc label (5), the digital memory is written by the writing device (9) (S4). When the movement of the pallet (2) is completed (S5), the imaging device (7) is stopped (S6), and the writing in the disk memory is completed (S7). If the pallet (2) is not closed (S5), the image pickup device (7) does not stop, and it is confirmed that the pallet has been closed. After the writing to the disk memory is completed, the music information is switched to the video signal by the digital / analog converter (11) and the video is amplified by the video amplifier (12). On the other hand, it is confirmed whether the normal video output signal is output by the switch signal from the control device (6) (S8), and when the normal video signal is not output, the disc level music information is displayed in the digital memory video. (S9). When the normal video display is output, the output is shut off and then the digital memory of the disc label is displayed. Furthermore, after the writing device (9) has stopped writing to the digital memory (S7), the disc label can be directly displayed as a digital memory image without generating a normal image signal output (S9).

Further, by adding another image pickup device (7), even if the track information is recorded on the B side of the LD, the disc label information on the B side can be read, and Similarly, the disc label can be displayed on the digital memory image.

Further, according to the present invention, it is also possible to directly monitor as shown by a broken line in FIGS. 3 and 5 during the image capturing work when the disc is inserted, which is a blank time for the user to capture the disc. Can be made effective.

Further, when capturing an image at the time of inserting the disc, in the case of a single-sided recording disc, when the face without the disc label is inserted on the image capture side, that is, when the disc is inserted in the opposite direction, it is stored in advance. It can also be used as a means for detecting erroneous insertion by a method such as comparison with the information on the board surface that does not have the disc label.

[0011]

[Effect of the device]

 When normal video is not output, the song on the disc label can be instantly displayed on the TV screen when the disc is inserted, so the waiting time between songs is reduced and the next song is played immediately from the hand. be able to. Also, since the disc currently being used is displayed, it is possible to instantly know that the user has inserted the wrong disc, so that the disc can be changed quickly. Further, by adding an image pickup device, disc label information on the B side as well as the A side can be displayed.
