DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus, a reproducing apparatus, and a recording apparatus which use a recording medium containing a recording medium such as a cassette with a memory in which a recording medium such as a tape is stored in a storage container and which has a memory. The present invention relates to a medium index information display method and a storage medium for the recording medium.

[0002]

2. Description of the Related Art A camera-integrated VTR for recording image information photographed by using a small tape cassette and its peripheral sound has been widely used. When an image is captured using such a camera-integrated VTR and image information and audio information are recorded on the tape of the tape cassette, a label sticker indicating information indicating the recorded content of the entire tape is attached to the tape cassette. To keep.

[0003] In this way, it is not necessary to reproduce the image information recorded on the tape each time and check the recorded contents of the tape. So that you can always check if you are.

Thus, for example, when there are a large number of tape cassettes on which image information is recorded, the tape cassette containing the tape on which the target image information is recorded can be simply arranged based on the information described on the label. The label seal is being used effectively, as can be found in

[0005] The information written on the label sticker attached to the tape cassette is index information indicating the contents of the entire tape. Hereinafter, in this specification, information indicating the contents of the entire recording medium such as a tape is referred to as recording medium index information.

[0006]

The label sticker on which the recording medium index information is described is used by being attached to the outside of a tape cassette or the like. However, it is troublesome and troublesome to create a label sticker by describing the recording medium index information and affix the label sticker to a tape cassette, and sometimes forget to make it later. If the recording medium index information is mistakenly described, it is necessary to newly create and re-attach a label sticker describing the correct recording medium index information.

Further, while the tape cassette is repeatedly used, the label sticker attached to the tape cassette may be peeled off, or characters written on the label sticker may become dirty and unreadable.

[0008] Therefore, in a camera-integrated VTR, a title driving function capable of recording a title character related to the content of a recorded image captured, for example, a character such as "athletic meeting" or "Christmas game" is superimposed on an image to be captured. Therefore, it is conceivable that a title character as a recording medium index information is superimposed on a photographed image and recorded using the title driving function.

[0009] However, in order to view the title character as the recording medium index information superimposed on the image by using the title recording function, the tape must be rewound to the position where the title character is superimposed and reproduced. However, it may take time and effort to confirm the title character.

In view of the above, it is an object of the present invention to easily and surely add recording medium index information indicating the contents of the entire recording medium for each recording medium without using a label seal or the like, and to add the added recording medium index. The purpose is to make it easy to see information.

[0011]

According to a first aspect of the present invention, a recording medium is stored in a storage container, and a storage medium having a memory is loaded therein. A recording device for recording image information in the recording medium, wherein index information creating means for creating recording medium index information indicating the contents of the entire recording medium, and the recording medium index information created by the index information creating means are recorded in the memory. And a recording unit that performs the recording.

In the recording apparatus according to the first aspect, the recording medium search information indicating the contents of the entire recording medium is created by the index information creating means, and this is stored in the storage medium containing the recording medium by the recording means. Recorded in memory.

Thus, the recording medium index information can be provided for each recording medium, and the recording medium index information is recorded in the memory of the recording medium storage.
Unlike a label seal, there is no possibility that the character is peeled off or written characters become dirty and cannot be recognized. Also, the recording medium index information is recorded in the memory of the recording medium storage, so that it can be read and viewed whenever necessary.

According to a second aspect of the present invention, in the recording apparatus of the first aspect, a display unit, a detection unit that detects an instruction to start a display process of the recording medium index information recorded in the memory, A reading unit that reads the recording medium index information recorded in the memory when the detection unit detects an instruction to start a display process of the recording medium index information recorded in the memory; A display control means for displaying the output recording medium index information on the display means for a predetermined time.

In the recording apparatus according to the second aspect, the detecting means detects, for example, that a recording medium storage material is loaded. That is, when the storage medium storage material is loaded, this is detected as an instruction to start the display processing of the storage medium index information.

When the detection means detects an instruction to start the display processing of the recording medium index information, the reading means reads the recording medium index information recorded in the memory of the loaded recording medium storage. The read recording medium index information is displayed on the display means for a predetermined time under the control of the display control means.

Thus, the user can view the recording medium index information of the recording medium recorded in the memory via the display means, for example, by a simple operation of loading the storage medium storage material. That is, the recording medium index information recorded in the memory can be viewed whenever necessary. For this reason, it is possible to prevent duplicate recording on a tape on which important information is recorded, thereby preventing erroneous erasure of important information that has been recorded earlier.

The camera-integrated V of this embodiment
In TR, the menu key 14 and the dial key 1 described above are used.
5 is operated, a cassette label is created as recording medium index information indicating the contents of the entire tape of each tape cassette, and this can be recorded in the cassette memory 26 of the tape cassette 20. I have. For example, when the tape cassette 20 is loaded in the camera-integrated VTR, the cassette label recorded in the cassette memory 26 of the loaded tape cassette 20 is read and displayed. .

Here, the cassette label as the recording medium index information is different from a so-called title which is displayed together with the photographed image information. That is, in this embodiment, as described above, the cassette label is index information of the tape indicating the contents of the entire tape, and there is only one cassette label for each tape.

In this embodiment, the cassette label is recorded in the cassette memory 26 in the following format.

[4] Data Structure of Cassette Memory The format of the recording data of the cassette memory can be the one defined as a standard corresponding to the digital VCR (see, for example, Japanese Patent Application No. 5-268056). In this case, the data recorded in the cassette memory 26 is composed of packs. A pack is a minimum unit of a data group, and related data is collected to form one pack.

In the case of this embodiment, the cassette label is recorded as text data. More specifically, the cassette label is a single text unit (see FIG. 5) for the cassette label,
6 is recorded. The text unit is of variable length, and the first four bytes PC0 to PC3 are a pack called a text header. Following this text header pack, text data is recorded.

As shown in FIG. 5, in the text header pack, the first byte PC0 is a header indicating the data content of the pack, and is "00011000" (18h).
Indicates that this text unit is a cassette label.

In FIG. 5, "TD" in the text header
"P" indicates the total number of bytes of text data following the text header pack. The “TEXT CODE” of the fourth byte PC3 indicates the type of the text code to be recorded. For example, ASCII code, JIS code, Kanji code, etc. are recorded. Then, text data is recorded after the fifth byte PC4.

As described above, in this embodiment, the cassette label is written in the cassette memory 26 as one independent text unit for the cassette label.

More specifically, as will be described later, the cassette label data recorded in the cassette memory 26 is read out when the tape cassette 20 is loaded in the camera-integrated VTR of this embodiment. Displayed as a cassette label.

Then, as described below, under the control of the main controller 300, cassette labels are created and erased from the cassette memory 26. That is, in this case, the main controller 300
Receives key input information from the key input device 17, determines whether the key is a key for instructing a process related to a cassette label or a key related to other tape running or mode change, and performs control corresponding to each key. Do.

FIG. 6 schematically shows a flowchart of the key input processing operation of the main controller 300 in this case.

That is, when the main controller 300 detects that there is a key input through the key input device 17, it enters the processing routine of FIG. 6 from step S1. Then, in step S2, the detected key input is received, and in the next step S3, it is determined whether the input key is a key for instructing a process relating to the cassette label or another key.

If it is determined in step S3 that the input key is a key related to tape running or the like other than the processing related to the cassette label, the flow advances to step S4 to perform control corresponding to the input key such as mechanical system control. For example, when the reproduction key of the key input device 17 is pressed, the main controller 300 sends a control signal corresponding to the reproduction key to the mechanical controller 400. Mechanical controller 400
Receives this, and controls the mechanical deck 500 to execute a reproduction process.

In this embodiment, processing such as creation and deletion of a cassette label is performed by the camera-integrated VTR.
Can be executed in the VTR mode. For this reason, the camera integrated type V of this embodiment
TR is in VTR mode, and step S3
If it is determined in step S5 that the input key is a key for instructing processing relating to the cassette label, the process proceeds to step S5,
Performs processing related to the cassette label.

If it is determined in step S6 that there is an instruction to end the processing related to the cassette label by the user's key input operation, the flow advances to step S7 to add the tape cassette 2 to the camera-integrated VTR of this embodiment.
It is determined whether 0 is loaded.

If it is determined in step S7 that the tape cassette 20 is loaded,
Proceeding to step S8, a process of writing or erasing data in the cassette memory 26 of the tape cassette 20 loaded in the camera-integrated VTR is performed. That is, in the case of processing for creating a cassette label, the cassette label data is written to the cassette memory 26, and in the case of the processing for erasing the cassette label, the cassette label data recorded in the cassette memory 26 is deleted. . The cassette label creating process and the erasing process will be described later.

If it is determined in step S6 that an instruction to stop processing relating to a cassette label has been issued, and if it is determined in step S7 that a tape cassette has not been loaded, the cassette memory 26 is accessed. Without this, this processing routine ends (step S9).

If it is determined in step S7 that the tape cassette is not loaded in the camera-integrated VTR, the process is terminated without accessing the cassette memory 26. The cassette label is created normally without being interrupted.

For this reason, the camera-integrated VTR is produced despite the fact that the cassette label is normally created.
If the tape cassette 20 is not loaded in the VTR, the created cassette label is temporarily stored in the built-in memory of the camera-integrated VTR. Then, the tape cassette 20
Can be written to the cassette memory 26 of the loaded tape cassette 20 when it is loaded into the camera-integrated VTR. As described above, the camera-integrated VTR of this embodiment can create a cassette label in advance.

[5] Creation of Cassette Label Of the processing performed in step S5, first, the creation processing of a cassette label will be described in detail.

To create a cassette label, as shown in FIG. 7A, by pressing the menu key 14, for example, “Cassette label creation” in the menu screen displayed on the LCD 11 is dialed. This can be done by rotating and selecting 16 and pressing the dial key 16 to determine.

As described above, in this embodiment, after the menu screen is displayed, the operation of only the dial key 16 can perform all of the cassette label creation and determination as described below. As described above, in this case, the dial key 16 functions as various selection input keys by a rotating operation by the user, and functions as a determination input key by a pressing operation by the user.

From the menu screen, select "Create cassette label".
Is selected and executed, 5 as shown in FIG.
This is a screen for creating a cassette label in which the hiragana of the zero sound and the control characters are displayed. Then, in the first screen of FIG. 7B, as shown in the figure, the “a” line, “ka”
Each row is in a selected state, such as row, "sa" row, and so on. By rotating the dial key 16, it is possible to select which row to select.

When the user presses the dial key 16 while a certain line is selected, "kana" in the selected line can be selected one by one. That is,
For example, when the “A” line is selected and the dial key 16 is pressed, one of “A”, “I”, “U”, “E”, and “O” is selected by rotating the dial key 16. can do. Then, when the dial key 16 is pressed in a state where one of the "kana" is selected, the selected "kana" is determined as a cassette label character. The determined character is displayed at the position of the display column of the created character string under the heading "Cassette label creation".

By repeating this operation, in this embodiment, for example, a character string as a cassette label of up to 10 characters is created in the work area of the built-in memory of the camera-integrated VTR. As shown in FIG. 7C, the generated character string is displayed at the position of the created character string display field under the heading "Cassette label creation".

As shown in FIG. 7C, when the dial key 16 is rotated to select the control character "Complete" and the dial key 16 is pressed, the main controller of the camera-integrated VTR is operated. 300 determines that the cassette label creation processing has been completed, and performs the processing of step S6 and subsequent steps as described above with reference to the flowchart of FIG.

At this time, when the tape cassette 20 is loaded in the camera-integrated VTR, a character string as a cassette label created in the built-in memory of the camera-integrated VTR is stored in the cassette memory 26 of the tape cassette 20.
Is written to. In this case, the cassette memory 26 contains
Text data of a character string as a cassette label is recorded as an independent text unit for cassette label data in the format shown in FIG.

Then, the screen returns to the menu screen as shown in FIG. 7 (D), and the created cassette label is displayed on the right side of the item “Cassette label creation” on the menu screen, and can be confirmed. To be. In this menu screen, when the menu key 14 is pressed, the display of the menu screen ends, and the display returns to the normal display screen.

Also, in this embodiment, FIG.
When the menu key 14 is pressed on the cassette label creation screen shown in FIG. 8B, the process of creating a cassette label is stopped. Then, as described above, the screen returns to the menu screen without accessing the cassette memory 26. That is, the process of creating a cassette label can be completed without creating a cassette label.

As described above, after the menu screen is displayed by pressing the menu key 14, the camera-integrated VTR according to the present embodiment operates the dial key 16.
By simply operating, a character string as a cassette label can be created and written to the cassette memory 26.

[6] Rewriting and Erasing of Cassette Label Next, rewriting and erasing of the character string of the cassette label recorded as a text unit in the cassette memory 26 as described above will be described. In this embodiment, the rewriting or erasing of the character string of the cassette label recorded in the cassette memory 26 can be performed during the processing of creating the cassette label.

When rewriting or deleting the character string of the cassette label recorded in the cassette memory 26 of the tape cassette loaded in the camera-integrated VTR, the menu screen (FIG. 8) is operated by pressing the menu key 14.
(A)) is displayed.

In this case, if the character string data of the cassette label is recorded as a text unit in the cassette memory 26, for example, when the tape cassette 20 is loaded into the camera-integrated VTR, the cassette Since the text data of the label is read and taken into the built-in memory of the camera-integrated VTR, the character string of the cassette label based on the taken-in text data is used by the OSD circuit 602, and FIG.
Is displayed to the right of the executable selection item "Cassette label creation".

Then, as described above, the dial key 16
Is operated and "Cassette label creation" is selected and determined, so that a cassette label creation screen is displayed as shown in FIG. 8B. In this case, as described above, the character string of the cassette label based on the text data read from the cassette memory 26 is “Cassette Label Creation”.
It is displayed at the position of the display column of the created character string under the heading.

For example, when the character string "Taro no Athletic Meet" of the cassette label is changed to "Jiro No Athletic Meet" and rewritten, the dial key 16 is turned by operating the dial key 16 in the same manner as in the creation of the cassette label described above. Then, the character “ji” is selected and determined as a character constituting the character string of the cassette label by performing a pressing operation. As a result, as shown in FIG. 8C, the changed character string of the cassette label is displayed at the position of the display box of the character string to be created under the heading of "Cassette Label Creation".

When the change input of the character string of the cassette label is completed, the control character [Complete] is selected and confirmed on the cassette label creation screen. Accordingly, the main controller 300 controls the memory control unit 700 to rewrite the text unit of the cassette memory 26 so that the changed character string of the cassette label becomes text data.

Then, the screen returns to the menu screen as shown in FIG. 8D, and the character string "Jiro no Athletic Meet" of the rewritten cassette label after the change is displayed as a selectable item. It is displayed on the right side of "Cassette Label Creation". As described above, the cassette label can be easily rewritten.

[7] Display of Cassette Label Next, the process of displaying the cassette label recorded in the cassette memory 26 of the tape cassette 20 as described above will be described. FIG. 9 is a flowchart for explaining a process of displaying a cassette label in the camera-integrated VTR of this embodiment.

In this embodiment, the cassette label display processing shown in FIG. 9 is executed when it is detected that a tape cassette is loaded while the power supply of the camera-integrated VTR is turned on. .

That is, when the tape cassette is replaced or the like and the tape cassette is loaded while the power supply of the camera-integrated VTR is turned on, the cassette label shown in FIG. 9 is displayed. Execute the process.
Also, when the power supply of the camera-integrated VTR is turned on while the tape cassette is loaded in the camera-integrated VTR, the main controller 300 of the camera-integrated VTR does not Is determined to be loaded, and a cassette label display process shown in FIG. 9 is executed. Note that a sensor is provided to detect whether or not the tape cassette is loaded.

As described above, when the main controller 300 detects that the tape cassette 20 has been loaded into the camera-integrated VTR of this embodiment, the main controller 300 proceeds to step S1.
The processing from 1 is started.

In step S12, the main controller 300 controls the memory control section 700 to read a text unit for a cassette label from the cassette memory 26 of the loaded tape cassette 20. The reading process in step S12 is a process of reading a text unit whose text header PC0 is “00011000” from the data recorded in the cassette memory 26, as described above with reference to FIG.

Next, the main controller 300 proceeds to step S13 to display the cassette label on the screen 11D of the LCD 11, the screen of the electronic viewfinder 601, and the screen of the monitor receiver connected to the output terminal 605. . That is, the main controller 300
By controlling the SD circuit 602, display information is generated based on the text data of the cassette label text unit read from the cassette memory 26, and the display information is generated via the image information superimposing circuit 603. 601 and output terminal 605.

In this case, in the camera-integrated VTR, since only the tape cassette is still loaded, the reproduced video or the captured video is not displayed, and for example, the cassette is displayed on a blue-back or black-back screen. Only the text of the label is displayed.

In this example, the display position, size, color and the like of the cassette label are determined in advance. That is,
As shown in FIG. 10, the screen is vertically divided into four blocks, of which block 2 is selected to be used for cassette label display.

The character string of the cassette label is as shown in FIG.
As shown in FIG. 0, one character is displayed in an area formed by four minimum division units, each of which is the minimum division unit BL when the display screen is finely divided vertically and horizontally into a matrix state. As described above, a character string as a cassette label of, for example, a maximum of 10 characters can be displayed. In this example, the cassette label is set to be displayed in a centered state in the block 2.

In step 13, when the character string of the cassette label is displayed, the main controller 300 monitors the timer provided in the camera-integrated VTR (not shown) to allow 5 seconds from the display of the character string of the cassette label. It is determined whether or not it has elapsed.

If it is determined in step S13 that five seconds have elapsed since the display of the character string of the cassette label, the process proceeds to step S15, where the display of the character string of the cassette label is deleted, and this processing ends. (Step S17).

Also, in the determination processing of step 13,
If it is determined that five seconds have not elapsed since the display of the character string of the cassette label, it is determined in step S16 whether a key operation such as a reproduction instruction has occurred.

If it is determined in step S16 that a key operation has occurred, the flow advances to step S15 to erase the display of the character string of the cassette label and terminate the process (step S17). Then, as described above, the main controller 300 sends a control signal corresponding to the key operation to the mechanical controller 400,
Executes processing according to key operation.

When it is determined in step S16 that no key operation has occurred,
The processing from step 13 is repeated.

Therefore, in the camera-integrated VTR according to this embodiment, for example, when the tape cassette is loaded while the power is on, the power is turned on when the tape cassette is loaded. It is determined that the tape cassette has been loaded (cassette-in), and the cassette label display processing described above with reference to FIG. 9 is executed.

In this embodiment, FIG.
As shown in FIG. 1 (A), from the display screen displaying the current time, the recordable time of the tape in the tape cassette, the remaining battery level, etc., the cassette label recorded in the cassette memory 26 of the loaded tape cassette 20 is displayed. Is displayed as a cassette label for 5 seconds, as shown in FIG. 11B.

Therefore, the user does not need to perform any special operation to load the tape cassette with the power turned on, or turn on the power with the tape cassette loaded. In the case of using a VTR, if one of the operations must be performed, the text data of the character string of the cassette label recorded in the cassette memory 26 is automatically read out. The character string of the cassette label is displayed. When the character string of the cassette label is displayed for 5 seconds, the display of the character string of the cassette label is automatically deleted, and the display returns to the original display screen as shown in FIG.

As described above, while the character string of the cassette label shown in FIG. 11B is being displayed,
When a playback key, a standby key, or the like is pressed, the camera-integrated VTR according to the present embodiment deletes the display of the character string on the cassette label and executes a process corresponding to the key operation.
