Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a digital image reproducing device using a digital audio recording and reproducing device.

BACKGROUND OF THE INVENTION In recent years, DigiMole image reproducing devices have been used to reproduce image data that has been recorded in combination with audio data using a digital audio recording and reproducing device.

An example of the conventional digital image reproducing apparatus mentioned above will be described below with reference to the drawings.

FIG. 3 is a conventional digital image reproducing device, which shows a subcode graphic reproducing device that uses subcodes of a compact disc (hereinafter referred to as CD).

In FIG. 3, 1 is a CD on which subcode graphics are recorded, 2 is a CD player, 3 is an audio playback device, 4 is a controller that decodes and controls the subcode signal, and 5 is a graphic video display that displays graphics. A RAM (hereinafter referred to as V-RAM), 7 is a graphic monitor television for reproducing the RAM, and 6 is a sub-code graphic reproducing device including the controller 4 and V-RAM 5.

The operation of the digital image reproducing apparatus configured as described above will be described below.

First, when a CD 1 having graphic data recorded in combination with audio data is played back by the CD player 2, the audio data is played back as a music signal by the audio playback device 3, and the graphic data is transferred to the subcode graphic playback device 6. The controller 4 in the subcode graphics reproduction device e decodes this information and sends it to the V-RAMs, which reproduce it on the graphics monitor television 7.

Problems to be Solved by the Invention However, with the above configuration, even if the same graphics have to be played for each song (for example,
commercial screen), all graphic data in C
Since it must be recorded in D in advance, C
There is a problem in that the actual amount of image information that can be recorded on D is reduced. Still, the graphic data recorded on a CD could not be rewritten, and it was impossible to change even something like a commercial screen displaying a popular song.

In view of the above-mentioned problems, the present invention provides a digital image reproducing device that is equipped with a ROM in which image data to be reproduced in a fixed manner for each song is recorded in advance, and is capable of reading out and reproducing image data from the ROM when necessary. It is.

Means for Solving the Problems In order to solve the above problems, the digital image reproducing apparatus of the present invention transfers a ROM in which image data is recorded, image data input from the outside, and image data recorded in the ROM to an external device. It is equipped with a controller that is controlled by status signals input from the controller, and a frame memory that converts image data into image output.

Effect of the Invention With the above-described configuration, the present invention can increase the number of images that can be reproduced by one digital signal recording medium by storing regularly reproduced image data in the internal ROM. By replacing the images, the reproduced image can be partially changed.

Embodiment Hereinafter, a digital image reproducing apparatus according to an embodiment of the present invention will be described with reference to the drawings.

'@1 Figure 1 shows an example of a digital image reproducing apparatus using a compact disc (hereinafter referred to as CD) player according to an embodiment of the present invention.

In FIG. 1, 11 is a CD on which audio and image information is recorded, 12 is a CD player for playing back CD 11,
13 is an audio reproducing device for reproducing music signals from the CD player 12; 14 is a ROM having image information; 16
16 is a controller that transfers image information from the CD player 12 or ROM 14 to a frame memory 16; 16 is a frame memory for reproducing image information on a TV or the like; 18
is a monitor TV, ROM14, controller 16
, frame memory 16 as a whole is a digital image reproducing device 17.

The operation of the digital image reproducing apparatus configured as described above will be described below with reference to FIGS. 1 and 2.

First, FIG. 2 shows the main signals in FIG. 1, and here is an example in which the pause signal of the CD player 12 is used as a status signal indicating a change in the status of the CD player in FIG. be.

When the pause signal is at a low level, the CD player 12 is playing, and therefore the image data on the CD 11 is transferred to the controller 1.
Sent to 6. Since the controller 16 sends this image data to the frame memory 16 and reproduces it as an image, the image data %n becomes a complete image output after being transferred. If CD
When the player 12 automatically enters the pause state due to an external operation or the end of a track, the pause signal becomes high level and the playback of C'D 11 is stopped.Therefore, the CD player 12
Thereupon, the controller detects the stoppage of the CD player using a pause signal, reads the image data lROM1 from the ROM 14, and transfers it to the frame memory 16. The frame memory 16 receives image data 4I-ROM1 from the controller 15 and outputs the image.

As described above, according to this embodiment, the image data is stored in the ROM1.
4 and a controller 16 that detects the status signal of the CD player 12, it is possible to increase the apparent amount of images recorded on the CD and to periodically transfer images in the ROM 14 between tracks of the CD. This is possible, and the image content can be partially changed by changing the ROM 14, so there is no need to create a new CD 11.

In this embodiment, the pause signal in FIG. 1 may be replaced by other status signals such as time information.

Compact disc player 12 may also be other digital audio equipment such as digital audio tape.

Effects of the Invention As described above, the present invention provides a ROM in which image data is recorded in a digital image reproducing device, image data input from the outside, and image data recorded in the ROM by a status signal input from the outside. By providing a controller to control the number of images that can be reproduced on one digital signal recording medium, the RO
By changing the contents of M, the reproduced image can be partially changed.
