The drive 7 in this apparatus comprises a disc tray 8 for conveying the optical disc 14 to a drive position, an optical pickup 10 for reading a signal recorded from a signal recording surface of the optical disc 14, and a disc tray 8 for housing. A scanner 9 that is housed in 100 and irradiates the label area of the optical disc 14 with light at the same time to generate image data of the label area from the reflected light.
A tray detector 1 that detects that the disc tray 8 is stored in the housing 100 and detects a loading state in which the optical disc 14 is stored in the housing 100.
3 and 3.

Reference numeral 11 in the drawing denotes a remote controller for remotely controlling the recording medium reproducing apparatus.
Next, the operation of the present invention will be described with reference to FIG.

FIG. 2 is a flow chart of a reproducing method executed by a program of the recording medium reproducing apparatus of the present invention.

This flowchart comprises steps S1 to S14.

Each step of this flowchart will be described below.

Step S1 is a start step of this program.

In step S2, the remote controller 1
2 is an execution step of a key / button input operation executed in 1. This step represents a key input operation provided on the remote controller 11 or an operation process of a button input device provided on the main body and including a power button.

At this time, if any operation is performed, the process proceeds to the next step S3.

Step S3 is a determination step for determining the validity of the operation of the key or button performed in the previous step S2.

In this step, if the key or button operation performed in the previous step S2 is valid (Y), the process proceeds to the next step S4, and if the operation is not valid (N), the step is repeated. The process returns to S2 to enter the standby state for key or button input.

In steps S2 to S3, the key /
It forms a waiting loop for button input.

Step S4 is a determination step for determining whether or not the disc is in the loading state. In this embodiment, since the optical disc 14 is carried by the disc tray 8, the tray is a detector and the tray is the casing 1.
By detecting whether or not the optical disc is housed in the housing 100, the housing state of the optical disc in the housing 100 is detected.

If the disc has been loaded (Y), the process proceeds to the next step S5. If the disc has not been loaded (N), the process proceeds to step S13.

The next step S5 is a step of performing an image scanning process for generating image data from the label area of the optical disc 14. Specifically, the scanner 9 irradiates the label area of the optical disk 14 with light at the same time when the disk tray 14 is housed in the housing 100, and scans the light to generate image data of the label area. .

In this step, after the generation of the image data is completed, the process proceeds to the next step S6 and the process of imaging this image data is performed. Specifically, it is imaged by processing the image data in the graphic generator 2.

After the processing of step S6 is completed,
The process moves to the next step S7. The imaged image data is captured as image data in the disc tray in addition to the label area of the optical disc 14. In this step, the process of detecting only the label portion from the imaged image data is performed.

Specifically, the graphics generator 2 extracts the luminance component and the color component of the generated image data, and based on the two conditions of the abrupt change of the luminance component and the abrupt change of the color component. To extract the image data corresponding to the label area.

When the extraction of the image data in the label area is completed, the process proceeds to the next step S8.

In this process, the detected image data is transferred from the graphics generator 2 to the memory 3 and stored in the memory 3 as disk image data. The memory 3 is a non-volatile memory that can hold data even when power is not supplied.

In this way, in this step, the image data in the label area of the disc is stored in the memory 3.

After the process of step S8 is completed, the process proceeds to step S9. Here, when the image display key is pressed in the step of determining whether or not to display the image data stored in the memory 3 by using the pressing of the image display key as a trigger (Y), step S1
The process shifts to 0, and if the image display key is pressed (N), the process shifts to step S13.

Step S10 is a step of displaying a disk image.

Specifically, the microprocessor 6 issues a command to the graphics generator 2,
The graphic generator 2 requests the memory 3 to transfer the image data of the stored disk image. After that, the graphics generator 2 takes in the image data from the memory 3, synthesizes it with the background image data, and the video encoder 1 converts this into a video signal and outputs it from the video output terminal.

The video signal output from the video output terminal is displayed by the monitor (not shown) as shown in the display example of FIG.

FIG. 3 is a diagram showing an example of an image displayed when the power of the recording medium reproducing apparatus is turned on.

After step S10 is completed, step S11
Processing shifts to.

Step S11 is a process for detecting whether or not the disc has been unloaded. Specifically, since the optical disk 14 is carried by the disk tray 8, whether the optical disk is unloaded into the housing 100 is detected by detecting whether or not the tray is housed in the housing 100 with a tray detector. It is for detecting whether or not it is stored.

As a result of the judgment, if the process is unloading (Y), the process proceeds to step S12, and if not unloading (N), the process is step S1.
Move to 3.

In step S12, the disk image data which is the image data stored in the memory 3 is erased. At the time of unloading, since the optical disc is carried out of the housing, it is necessary to update the image data of the optical disc, which is information for identifying the loading disc. Therefore, the data in the memory 3 is once cleared.

In step S13, the power off state is confirmed. If the power is off in this step (Y), the process proceeds to step S14. Step S
Reference numeral 14 is an END step, which performs processing for stopping the system.

If it is determined in step S11 that the disc is not in the unloading state, the erasing process of the disc image data in step S12 is not performed. That is, when the disk is stored in the housing 100, the memory 3 continues to hold the image data of the stored disk.

For example, in step S13, the memory holding operation of the nonvolatile memory 3 is maintained even when the power is off (Y). Therefore, when the power is turned on again, the pressing of the image display key is triggered. In the case of occurrence of, the image data stored in the memory 3 is read out, and the image of the accommodated disc becomes a video signal and is displayed by a monitor not shown.

The above is a series of operations of the present invention. Further, the image display is triggered by pressing the image display key in this flowchart, but this image display trigger may be other than the one obtained on the system.

For example, when the recording medium reproducing device is a changer type optical disc reproducing device, the data shown in FIG. 4 is held as the content data to display the image data stored in the memory at various timings. be able to.

FIG. 4 shows an example of content data when a plurality of disks are stored in a changer type housing.

A disc number is given to the disc when it is stored. Further, the microcomputer 6 reads the management information of the stored optical disc, takes in the information of the chapter and the song number as contents, and stores it by linking with the disc number.

Further, at this time, the image data of the disc read by the scanner 9 is stored in the memory 3 and the disc number of the content data is linked and stored, whereby the content data shown in FIG. 4 is constructed. .

These contents data are stored in the internal memory of the microprocessor 6.

An example of a screen including this content data and displayed as a trigger is shown in FIGS.

In the display examples (a) and (b) of FIG. 5, a video signal is generated based on the image data already stored in the memory 3 at the time of loading operation by using the start signal as a trigger for starting tray loading. Output this.

At the beginning of the loading operation, the diagram (a) is displayed, and the content data of FIG. 5 is created based on the management information of the loaded disc.

Since the currently loaded disc is stored in the tray of disc number 1, the disc number 1 is given, and the disc is stored in association with the image data of the disc image read by the scanner 9.

The diagram (b) is based on this management information.
The title and chapter number in the figure are displayed. As described above, since processing such as disc discrimination is performed at the time of loading, it takes a considerable time for reproduction. Therefore, it is very difficult to display the image data of the disc image stored in the memory 3 as an image during this period. It is valid.

The example of FIG. 6 is a display example when reproduction is performed by a recording medium reproducing device having three trays.

The initial screen is (a). In this screen, the image data of the trays B and C that have been captured in advance are captured.

The data corresponding to each tray is taken in by the scanner 9 for each tray when the disc is stored, and is combined with the background image by the video encoder 1, as a result, (a),
A screen as shown in (b) is constructed.

In FIG. 5A, the blank image in the portion of the tray A corresponding to the disc indicates that the tray A is an empty tray.

Here, when an optical disk is mounted on this tray A and loaded, the display of FIG. In FIG. 6B, the image data of the tray A is also fetched in the memory 3 and is combined and displayed as one image.

In this display example, by comparing and referring to FIGS. (A) and (b), it is possible to see at a glance which tray the disc is loaded in in the changer type recording medium reproducing apparatus.

As described above, in the recording medium reproducing apparatus of the present invention, the recording medium (optical disk) in the recording medium reproducing apparatus can be easily recognized by capturing the image in the label area of the optical disk as data.
