Are compared, and when they match, the control signal 8A is used to instruct the memory controller 4 to input the still image output time signal S2 from the system controller. This still image output time signal S2 is stored in the RAM from the beginning of the chapter.
5 shows the time until the writing of the video signal 3A to the signal 5 is started. That is, in a karaoke laser disc or the like, the title of the song is always included at the beginning of the song, but the time from the beginning of the chapter until the title appears varies depending on the software maker. Therefore, the still image output time for each software maker is registered in advance in the memory of the system controller, and when the still image is output, the still image output according to the software maker of the disc currently set in the disc reproducing device is output. The image output time is read from the memory and input to the memory controller 4.

Further, 9 is an image scanner incorporating a CCD line sensor 10. The image scanner 9 is used to read character image information such as a reservation person's name written on the karaoke reservation card C as additional image information on a still image. The image scanner 9 is provided with a movement detector 11 for detecting the amount of movement of the image scanner 9 in the sub-scanning direction per unit time. Examples of the movement detector 11 include a type in which a rotating roller is provided on the input surface side of the image scanner 9 and the amount of rotation of the rotating roller is measured as the image scanner 9 moves in the sub-scanning direction. .
Further, the output end of the movement detector 11 is the distance / voltage conversion circuit 1
2 is connected to the input end. The distance / voltage conversion circuit 12 generates a voltage 12A proportional to the movement amount 11A per unit time detected by the movement detector 11 to generate a voltage / voltage.
This voltage 12A is supplied to the pulse conversion circuit 13. Further, the voltage / pulse conversion circuit 13 generates a pulse signal 13A having a frequency corresponding to the supply voltage 12A, and outputs the pulse signal 13A to the field memory 14 and the clock ON / OFF.
It is supplied to the controller 15, respectively. Also clock O
The N / OFF controller 15 sends the clock signal 15A to the CCD driver 1 at the rising edge of the pulse signal 13A.
The CCD line sensor 10 is driven by outputting it to 6. However, before the movement of the image scanner 9 is started, the CCD line sensor 10 is driven based on the clock signal 4B given from the memory controller 4. Field memory 1
Reference numeral 4 captures and stores one line of additional image information 10A from the CCD line sensor 10 at the rising edge of the pulse signal 13A input from the voltage / pulse conversion circuit 13.
A controller 17 controls reading of additional image information for one reservation card stored in the field memory 14 and transfer to the memory controller 4. The controller 17 executes its control according to the input of the multiple control signal S3 from the system controller.

Next, the operation of the still image creating apparatus of this embodiment will be described. First, the chapter number S1 is input to the chapter code detection & controller 8 through the system controller by the user designating the chapter number as the reserved tune.

After that, when the disc reproduction is started, the chapter code detection & controller 8 inputs the chapter code signal 1B from the video signal processing circuit 1 and decodes it, and the decoded chapter number and the chapter number of the reserved music.

When the still image output time signal S2 is input to the memory controller 4, the timer is started, and after the time indicated by the still image output time signal S2 has elapsed, one field of the input image signal 3A is written in the RAM 5. . As a result, the video signal of the title portion of the reserved song is stored in the RAM 5 as still image information.

After that, the video signal stored in the RAM 5 is converted into an analog video signal 6A by the D / A converter 6 and then output to an external television through the amplifier 7 and displayed as a still image.

On the other hand, the user reads the image of the karaoke reservation card C by using the image scanner 9 after finishing the designation of the chapter number. The additional image information thus read is stored in the field memory 14.

In the meantime, the movement detector 11 detects the movement amount of the image scanner 9 per unit time.
The detection signal 11A is input to the distance / voltage conversion circuit 12,
Here, after being converted into a voltage 12A proportional to the movement amount, it is input to the voltage / pulse conversion circuit 13. Further voltage 12
A is converted into a pulse signal 13A having a frequency corresponding to the voltage level by the voltage / pulse conversion circuit 13, and the field memory 14 and the clock ON / OFF controller 1
5 is supplied. In this way, the clock generation based on the movement amount of the image scanner 9 is performed so that the image information is read by the image scanner 9 with a constant resolution even in the sub-scanning direction.

Thereafter, the system controller inputs the multiplex control signal S3 to the memory controller 4 and the controller 17. Then, the controller 17 reads the additional image information from the field memory 14 and inputs it to the memory controller 4. On the other hand, the memory controller 4 determines the read timing of the additional image information so that the additional image overlaps the still image at a specific position with reference to the vertical synchronizing signal of the still image, and the additional image information is added to the still image of the portion overlapping with the additional image information. The information is replaced and output to the D / A converter 6.

Thus, according to the still image creating apparatus of this embodiment, a character image such as a reservation person's name can be superimposed and displayed on the still image of the program title section as additional image information relating to this still image. Therefore, by incorporating the still image creating apparatus of this embodiment into each disk reproducing apparatus in the disk playing apparatus with the disk autochanger function, and by additionally connecting two televisions externally, one disk reproducing apparatus While playing the music, the other disc reproducing apparatus can provide the user with a service such that the title of the music to be played next and the name of the reservation person are displayed as a still image.

Next, another embodiment of the present invention will be described. Figure 2

That is, the video signal input via the switch circuit 22 is input to the sync separation & clamp circuit 23. The output of the sync separation & clamp circuit 23 is input to one input terminal of the phase comparator 24. The output of the frequency divider 26 that divides the oscillation frequency of the voltage controlled oscillator 25 is input to the other input terminal of the phase comparator 24. The output of the phase comparator 24 is input to the voltage controlled oscillator 25 via the equalizer circuit 27.

Next, the operation of the still image creating apparatus will be described. Now, it is assumed that the second disk reproducing device 21b is connected to the still image creating device via the switch circuit 22.

When the disc reproduction is started by the second disc reproducing device 21b, the reproduced video signal is inputted to the sync separation & clamp circuit 23 via the switch circuit 22. The sync separation & clamp circuit 23 separates the horizontal sync signal 23A from the input video signal, and the phase sync 24
Input to one input end. The phase comparator 24 compares the phase of this horizontal synchronizing signal with the output signal of the frequency divider 25 input from the other input terminal, and supplies a voltage corresponding to the phase difference to the voltage controlled oscillator 25 via the equalizer circuit 27. Output.
As a result, the oscillation frequency of the voltage controlled oscillator 25 is controlled so that the phase difference becomes the minimum necessary, and this oscillation frequency is supplied to the memory controller 4 as the master clock 25A.

Thereafter, the memory controller 4 controls the still image creation according to the master clock 25A.
