Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording / reproducing apparatus capable of associating previously recorded image / sound information with newly recorded image / sound information on the same recording medium.

[0002]

2. Description of the Related Art As represented by a CD medium, an information reproducing apparatus using a large-capacity optical disk as an information recording medium has already been proposed in various product forms, has a wide variety of application fields, and is in demand. It is expanding. This means that the manufacturing cost of the disk medium itself has dropped dramatically, and it has become possible to provide software that is cheaper than other types of media, and it is also possible to record a large amount of information on a single disk. The system that makes the best use of the characteristics of the media is just beginning to be recognized by users.

At present, the mobile information reproducing apparatus is receiving particular attention. This is used by displaying information recorded in a format such as CD-ROM on an optical disc set in the main body of the device on a small liquid crystal display or the like, and not only image data but also audio data can be used. There are many things. Also, as for title software, various title software has been released depending on the purpose of use. This includes software that makes it easy to handle large amounts of data using the search function, such as encyclopedias and English-Japanese dictionaries, travel guide software that makes the most of the portability of the device, or map information and playback on disk. A system that has been developed as a navigation system by combining the GPS function of the device has also appeared.

Among these, in the field of guide information, a rental system has been considered for utilizing information. For example, when using the information reproducing device as a travel guide, a player can borrow a reproducing device and a disc on which guide information is recorded at a tourist spot, access and use necessary information on the disc while traveling, and after use, It will be returned. Such a system not only enables the user to quickly obtain the necessary information when and when it is needed, but also makes it possible to always obtain the latest data locally. In addition, the recent cost reduction of disks is convenient for information providers, and in the case of books, it is necessary to publish several types by region, but in the case of disk media, almost all information is stored in one sheet. It is possible to pay in. It is expected that there will be more and more systems that can realize such information utilization systems by rental methods.

On the other hand, electronic still cameras have appeared as next-generation cameras, but they have not come into widespread use because of the high system price and low recognition by the general public. It is only used in special fields such as image input devices. Most of the recording media use a magnetic disk or a semiconductor memory card, but generally speaking, a memory card is more advantageous in terms of image quality. However, in recent years, the bit unit price of semiconductor memory has been acceleratingly low, but the cost is still disadvantageous compared to photography using general film. However, with the progress of multimedia in various fields in recent years, many data recording devices using optical disk media have appeared. In terms of price, it is close to the media that have been used so far, and it is expected that recordable optical disk media will be widely used in general households in the future, so it will be used for photography. It is considered that optical disc media will be used more frequently.

Here, focusing on the point of data association, in the case of an information reproducing apparatus such as a travel guide as shown in FIG. 19, data is often hierarchized. On the other hand, image data taken by an electronic still camera or the like is associated in a continuous state as shown in the figure on the taken stairs. In this case, these two data groups are not associated. If you wanted to make these connections, you needed to edit them later.

[0007]

However, in a situation where both an information reproducing apparatus using such an optical disc and an electronic still camera are needed, for example, a trip or the like, the information reproducing apparatus utilizes the travel guide information while using the electronic still camera. Up until now, I had to have these two devices separately in situations such as taking a commemorative photo, which was very troublesome. Also, while shooting, there is no such thing as linking the shooting location and guide information about that location and recording together, which can be played immediately and continuously.
If you want to link these pieces of information, you need a special editing machine that is different from the conventional electronic still cameras, and there was no way to edit while shooting.

Therefore, the present invention has been made in consideration of the above problem, and it is possible to record images / sound information previously recorded on an optical disc and newly photographed image / sound information on the same disc in association with each other. It is an object of the present invention to provide an information recording / reproducing apparatus that can reproduce these continuously.

[0009]

In order to achieve the above object, according to the present invention, image / audio information (first
(Information of) is a device for handling a recording medium on which is recorded, in an area different from the partial area on the recording medium,
It is possible to create additional recording means for additionally recording image / sound information (second information), association information of the additionally recorded information, and already recorded information, and record it in the recording medium. The related information recording means and the information recorded on the recording medium are selected and reproduced, and other information related to the reproduced information is selected and reproduced by referring to the related information. And a reproducing means capable of performing the reproduction.

[0010]

With this structure, the image / sound information previously recorded in a part of the recording medium and the image / sound information captured can be recorded in the same recording medium, and the information can be associated with each other. Therefore, it is possible to continuously reproduce and display related information.

[0011]

Is a system for outputting data from the TV to another playback device such as a TV monitor. On the other hand, the data read from the image memory 12 is sent to the LCD drive unit 4 and displayed on the LCD unit 5, and the audio data converted into analog by the recording / playback unit is output from the speaker 6. It is a system that is played by the camera alone.

FIG. 2 shows data types on the optical disc 9 and their recording areas. Although data of travel guide information is recorded in advance on the optical disc, this is recorded in the guide information area 23 located on the inner peripheral side of the disc. The captured image data and audio data are sequentially recorded as user data in the user data area 24 located outside the guide information area on the disc. Although the optical disc is a rewritable type, the travel guide information in the guide information area is read-only, and rewriting or addition of data is prohibited by software under the control of the CPU 15.

FIG. 3 shows an example of the data format of the TOC (table of contents) area 25 on the disc. The TOC area 25 is provided in the innermost lead-in area on the optical disc, and the TOC data for each image / audio data is recorded in the image / audio data.
The audio data is sequentially recorded in the order of arrangement. The TOC data of the captured image / sound data is sequentially recorded after the series of image / sound data of the guide information. At this time, the data numbers are consecutively added to the guide information. Further, of the TOC area, information related to guide information is read-only, and the user's arbitrary rewriting or addition is prohibited by software under the control of the CPU 15. However, regarding the link information described below, the information related to the guide information can be rewritten only when the information is necessary for associating the guide information with the user data. Also, the TOC data of the photographed data is
It can be rewritten and added by the user, but the area for writing the TOC data has a sufficient area for the predetermined number of shootable images. In the example of the figure, it is shown that the recording data is captured from the (n + 1) th.

FIG. 4 shows an example of the data format of the guide information area and the user data area. One block of each data has a header for identifying the beginning of the data, followed by the main body of image or sound data. The captured image / sound data is sequentially recorded after the image / sound data of the series of guide information. The example shown in this figure corresponds to the TOC data shown in FIG. 3, and the first to nth data are the data of the prerecorded guide information, and the data after n + 1 are newly photographed and recorded by the user. Indicates that there is user data. Therefore, this figure shows the guide information area 23 and the user data area 24.
(See also FIG. 2) Boundary data is shown.

FIG. 5 shows an example of the format of one TOC data in the TOC area. The TOC data is a data number 26 assigned in the order of arrangement of the data body, type data 27 indicating whether it is image data or audio data, and guide information (read only except link information) or user data (read / write). A pointer 28 indicating the recording location of the data body in the guide information area and the user data area, four directions in which the numbers of other data linked to this data are linked, that is, the previous menu 29, the next menu 30, the previous page 31, the next page. It is recorded in the order of 32 directions.

By setting this data number, information link information can be obtained. Therefore, this link information is used as information for associating the image / audio information.
FIG. 6 shows a hierarchical link structure of image / audio data.

As shown in the figure, the direction from the upper layer to the lower layer is the menu direction, and as it goes to the upper layer, it becomes closer to the route, and the top is the top screen. In the same layer, the horizontal direction of the drawing is the page direction, and the right is the root direction. In the example of FIG. 6, the screens are numbered with menu numbers and page numbers, and the top screen is 0.
101 screen.

Therefore, taking the case where the data of the 0201 screen is present at the access center as an example, the number 0101 in the previous menu area, 0301 in the next menu area, and the next page area in the TOC data are taken as an example. Is recorded as 0202, and 0 (no data in the corresponding direction) is recorded in the previous page area.

FIG. 7 shows an example of linked data of image / audio information and TOC data having a linked hierarchical structure. * 1 to * 12 are guide information recorded in advance on the optical disc and are examples of "Tokyo Town Guide". Here, the transportation is displayed after the top screen * 1 * 2. The next screen is a menu screen * 3 for each area. Select the desired area here * 4 ~
* 7 Each area can be placed in a different hierarchy.

[0025] * 13 and * 14 are data of a commemorative photograph newly photographed and recorded, and are recorded by being linked to the information of "Yoyogi Park" in * 12. That is, it is shown here that it is a commemorative photo at Yoyogi Park.

FIG. 8 shows the TOs of * 4 and * 13 in this case.
An example of C data is shown. In * 4, the code of 04 indicating the screen (data) number is recorded first, and then the code indicating that the data is an image and is read only (guide information in this case) (01 in this example) is recorded. Next, a pointer indicating the location of the data body on the disc is recorded, and then the link information is recorded.
The link information is 03 showing the screen * 3 for selecting Hachiko-mae to Ginza in the previous menu area, 08 showing the screen * 8 of the southern department store in the next menu area, and the screen of Kabukicho in the next page area. * 05 indicating * 5 is recorded. Since there is no data in the area on the previous page, 00 is recorded. Information linking the guide information (read only) is recorded in areas other than the previous page in the link information, so that it is rewritable (because other data such as shooting data is newly associated). Only in the direction of the previous page. *
In No. 13, first, a 0D code indicating the screen (data) number is recorded, then a code indicating that the data is an image and user data (02 in this example) is recorded, and then the data main body is recorded. A pointer indicating a location on the disc is recorded, and then link information is recorded. As for the link information, 0C showing the screen * 12 of Yoyogi Park in the previous menu area, 0C showing the screen of * 14 which is the souvenir picture 2 in the next menu area, the area of the previous page and the next page, Since there is no data, 00 is recorded. Of these link information, the information to which the guide information (read only) is linked is recorded in the area of the previous menu, so it is possible to rewrite (being able to newly associate other data such as shooting data). Only the direction other than the previous menu is available.

As described above, this example has a structure in which prerecorded information and newly added related information can be linked to each other. FIG. 9 shows another example of linked image / audio information having a hierarchical structure.

This is an example of an optical disc on which information of the XX town adult ceremony is recorded, and XX is previously recorded on this optical disc.
Information about the XX town such as the history of the town is recorded.
Image / sound information taken in the adult ceremony is recorded by linking to a menu screen for arranging according to the content and location of the photograph. Such a disc has a structure in which town information and photo information are systematically linked.

FIG. 10 shows an example of the operation keys of the camera for reproducing linked image / audio information of a hierarchical structure or for recording by linking to other information. Here, the keys 33 and 34 are for selecting data in the page direction, the keys 35 and 36 are for selecting data in the menu direction, and the shutter "1" key 37 is for inserting the photographing screen in the page direction and the shutter "1". The 2 ”key 38 is for inserting the photographing screen in the menu direction.

FIG. 11 shows an example of a tree guide display showing a link structure and a data connection structure on the screen. In the screen a, an arrow display as shown in the figure is superimposed on the screen for display. This is an example in which the CPU 15 determines the direction in which another screen is connected (linked) to the screen currently displayed and generates display data. in this case,
Arrows correspond to the menu and page direction selection keys in FIG. 10, and screen a shows that there are screens for the previous menu and the next menu and next page, and these can be selected.

The screen b is an example in which the entire link structure is displayed in a tree shape and is superimposed on the screen. Here, the white square indicates the current position of the display screen, and indicates that the fourth data is displayed in the direction of the next menu from the top screen. In these cases, if the screen is overwritten, it becomes difficult to see the screen. Therefore, it is desirable to average the already displayed color and the drawn color. Although the guidance display is displayed on the screen in this case, it is also possible to open the guidance information and the guidance display on the screen as separate windows, for example. is there.

FIG. 12 shows an example of an operation flow for displaying the linked information in the present invention. First,
If the user gives an instruction to display information using keys, the CPU
The unit refers to the TOC area of the disc or the TOC data that has already been read into the memory of the CPU when the system is started up, accesses the image data, and displays it on the LCD unit (steps A1 to A1).
A5). At this time, the link information in the corresponding TOC data is referred to, the data other than 00, that is, the direction in which the data is present is checked, and the arrow display like the screen a in FIG. 11 is generated and displayed on the screen (step A6). ~ A7). At this time, the CPU unit always stores the direction in which the data exists for the current screen in the memory or the like in the CPU unit. The top screen may be displayed when the system is activated, or the screen at the time of the previous termination may be stored in the memory of the CPU unit or the like and the operation may be started from there.

Here, when the user inputs a next information display instruction through a key for selecting information corresponding to the arrow on the screen (an example is shown in FIG. 10), the CPU section is instructed. The direction in which the stored data exists is checked with respect to the direction. If there is no data, the next instruction is awaited (steps A8 to A10). When the existence of data is confirmed, the TOC data is referred to, the next data is accessed, and the data is displayed. Also, the TOC data of the displayed data is referenced to check the direction in which the data exists, and the arrow indication of the new link structure is displayed (steps A11 to A13).

FIG. 13 shows an example of the operation flow in the case of displaying linked information and linking the recorded image data for recording. First, when the user gives an instruction to display information with the key, the CPU section refers to the corresponding TOC data, and accesses and displays the data in the corresponding direction. Then, a new link structure is displayed based on the TOC data (steps B1 to B5). If there is a shooting instruction here,
Check if the shooting data can be linked in the specified direction. If there is guide information or erasure-prohibited data in the pointing direction, the camera waits again for a shooting instruction. At this time, a warning may be displayed to prompt the user to select (steps B6 and B7). If it is determined that the shooting data can be linked, the shooting data is captured, the shooting screen is displayed, and then additionally recorded in the user area (B8 to B10). Here, new link information is added and a new link structure is displayed on the screen (B11 to B12).

FIG. 14 shows the block configuration of the second embodiment of the present invention. In this embodiment, an M sequence section 39 for scrambling data is newly provided as compared with the previous embodiment. The other parts are the same as those in the previous embodiment and are therefore given the same reference numerals. The M series unit 39 controlled by the CPU 15 is provided so as to be associated with the video data line and the audio data line.

The M-series section is a pseudo-random number generator circuit using a general shift register. FIG. 15 shows an example of the data format of the TOC area in this embodiment.

In the TOC area of the optical disk, a password for determining whether to permit the use of pay data on the disk and a scrambled data group recorded on the disk are scrambled at the time of reproduction. The key information for unlocking and one data are recorded on each disc. The TOC data corresponding to each guide data is added with a reproduction permission flag indicating unconditionally permission to reproduce the data.

FIG. 16 shows a flow of the system operation when reproducing the above optical disk. First, the password is read from the TOC area on the disc, and it is determined whether or not the pay data (reproduction permission flag is not allowed) is used (steps C1 to C3). In the case of non-conformity, only those for which the reproduction permission flag of the screen to be reproduced is permitted are displayed, and those for which the reproduction is not permitted are skipped and the process proceeds to the next screen (steps C4 to C8). If the password is compatible, the key information in the TOC area is read in order to descramble the data and set as the initial value for the pseudo-random number generation of the M-sequence generator (step C9). It is desirable that the key information is not an immediate value but is subjected to some processing. If the reproduction permission flag of the data to be reproduced is disabled, an initial value is set in the M-sequence generator, and if it is permitted, the data is not scrambled, so the M-sequence generator is disabled for reproduction. Perform (steps C10 to C16).

According to such a configuration, in a system for renting out a camera for rental, when purchasing a photo recording system (system or optical disk), reproduction of pay data in the guide information is not permitted, and By scrambling in advance, the purchase price can be reduced. The price can be increased if the scramble is released.

FIG. 17 shows various link structures in the case of new shooting, overwriting shooting, addition of options, deletion, and restoration of picked-up image / sound information. Figure 1
7 (a) is the data of P0401, P0501 and P07
Example of linking 01 photo data in the direction of the next menu.
FIG. 17B shows an example in which the data of P0401 is linked with the two-photograph data in the next page direction. FIG. 17C shows FIG.
An example in which P0701 is overwritten on the data of P0401 in (a) and the link location is set to the menu next to P0601.
Item 17 (d) is an example in which option P0401 is added. Figure 1
7 (e) is an example in which the data of P0501 in FIG. 17 (a) is removed from the link. FIG. 17 (f) shows FIG. 17 (e).
This is an example in which the data P0501 removed from the link in 1. is linked to another place and restored. These are performed by checking and rewriting the link information recorded on the disc as described above.

In the above embodiment, the link between the photographed data and the guide information has been described as an example, but the data linked to the guide information is not the photographed data but is shown in the block diagram of FIG. Such as the external input terminal 41,
It may be a link to video data or audio data input from 42.

In the above system, for example, a traveler borrows an electronic still camera with an information function equipped with an optical disc on which travel guide information and the like are pre-recorded at a rental store installed in a tourist resort or an airport, and during travel, Take a photo while accessing the required guide information on the disc. At this time, as described above, the guide information and the photographed data are associated and recorded. For example, the photograph data taken while using the guide at the point A is recorded so that it can be reproduced continuously with the guide screen at the point A. This makes it possible to immediately display relevant information such as where the photo was taken, eliminating the need for post-editing of the data normally required.

A system in which this camera is returned to a rental store after use and only the disc is purchased or the camera is also purchased is conceivable. In either case, the guide data on the disc is encrypted as described above,
Reasonable charges can be made only for the protection of copyrighted materials and guide information required by users.

Although the recording medium is an optical disk in the embodiment of the present invention, a magnetic disk, which has recently been remarkably miniaturized and has a large capacity, may be used. In the above embodiment, the image
Although it is shown that the audio signal is handled, various combinations are possible as a combination of the information recorded in advance on the disc and the type of information additionally recorded later. For example, it may be a combination of an audio signal (image signal) and an image signal (audio signal). Further, it may be an image signal and general data (numerical value or parameter) introduced from the outside.

[0045]

As described above, the image / sound information that is partially recorded in advance and the newly shot image / sound information are recorded on the same recording medium, and the respective pieces of information are associated with each other. Since this is possible, related information can be continuously reproduced and displayed.
