Description

The present invention relates to a reproducing apparatus and a control method for reproducing contents information such as image or sound.

  In recent years, JPEG (Joint Photographic Expert Group) format image files are transferred directly from a recording / playback device such as a digital video camera or digital still camera to a printer via a USB without using a personal computer (PC). A so-called direct print system for decoding, processing data for printing, and printing a photograph is becoming widespread. Further, a printer that inserts a flash memory card into a printer and prints a JPEG image file read from the flash memory card by the printer is also commercialized. There has also been proposed a printing system that performs index printing by directly outputting playback video data for so-called index printing (thumbnail printing of all images) to a printer using a drawing memory in the camera body without using a personal computer. (For example, refer to Patent Document 1).

The image file transferred from the playback device is analyzed by the printer, and the accompanying information data of the image included in the image file is combined with the image and printed in a predetermined layout. .

  On the other hand, in recent years, a writable DVD media (disc) PC drive device and video recorder have rapidly spread, and a user arbitrarily collects self-made images (captured images) and writes them to the DVD media according to the DVD-Video standard. It is easy to make. In such a case, if there is a label print function for showing the contents of the DVD medium, it is convenient for the user and the demand is high.

The above-described printer system can also realize the label print function, but it is limited to the print contents of the image title name and the shooting (recording) date and time. As the print contents for label printing, the content management information in the media (for example, folder structure, TOC (Table Of Content) information, menu information, etc.) is more information than the title name for each image. It is highly useful and useful.

<Operation of generating management information image file>
In the present embodiment, a user can perform an operation to generate management information such as the TOC screen as an image file for label printing on the recording medium 1. This is a feature of the present embodiment that is not in the prior art.

  Hereinafter, an operation after the user instructs execution of an operation for generating an image file of TOC information using the operation key 114 will be described with reference to FIGS. 4 and 5.

  FIG. 4 is a flowchart showing the management information image file generation operation according to the present embodiment. FIG. 5 is a conceptual diagram for explaining a state of drawing and scanning during an image file generation operation of management information according to the present embodiment. This image file generation operation is executed under the control of the system control circuit 113 after the user gives an instruction to execute the operation of generating the TOC information image file using the operation key 114 (image file generation operation).

  First, in step S301, a user operation detection process is performed. In the next step S302, it is determined based on the result of the detection process whether the user has performed an operation for generating an image file of TOC information using the operation key 114. When the image file generation operation is not performed, the image file generation operation is terminated. If an image file generation operation has been performed, the process proceeds to step S303.

  In step S <b> 303, the drawing contents of the drawing memory circuit 110 are temporarily deleted, and the TOC information in the range in which the image file is generated is drawn in the drawing memory circuit 110 among the TOC information of the contents in the recording medium 1. Reference numeral 403 in FIG. 5 two-dimensionally represents a drawing area to be drawn and displayed by the drawing memory circuit 110, and TOC information that is management information is visually drawn.

  Note that reference numeral 402 in FIG. 5 denotes a range displayed on the LCD display 112 in the data drawn on the drawing memory circuit 110 by the drawing circuit 107. In the display operation on the LCD display 112 described above, the drawing information displayed on the LCD display 112 is a display (focus display) being selected on a display button or the like that is an operation instruction target, as indicated by reference numeral 407 in FIG. 407a was added. On the other hand, in the drawing operation for generating the image file, as shown by 403 in FIG. 5, the focus display 407a is not performed. As for the drawing range of the image, the display on the LCD display 112 (407 in FIG. 5) uses the screen scrolling method by narrowing the drawing range. Assuming the purpose, the drawing range is widened so that the image is displayed in one image file as much as possible.

  In the next step S304, the image of the TOC information drawn in the drawing memory circuit 110 in step S303 is scanned to generate print image data. In further subsequent step S 305, the print image data of the drawing memory circuit 110 is sequentially read by the print image reading circuit 111 and compressed by the JPEG method in the still image CODEC circuit 108.

  403 in FIG. 5 indicates a range of data read by the print image reading circuit 111 as print image data, and 408 indicates an image file read as print image data (contents of data in the range indicated by 403). Indicates. In this image file, the focus display 407a and the operation displays 404 to 406 are deleted. Instead, the drawing and scanning range is not limited to the LCD display range, and has a predetermined shape suitable for printing.

  In step S306, the JPEG compressed image output from the still image CODEC circuit 108 is recorded in the form of a still image file on the recording medium 2 (SD card) in accordance with the DCF standard.

  After generating the TOC information image file that is the content management information of the recording medium 1 and recording it on the recording medium 2 in this way, the process proceeds to step S307, where the LCD again displays the user interface display of the camera body. A TOC screen for display is drawn on the drawing memory circuit 110. The drawing image at this time is an image to which a focus display 407a and operation displays 404, 405, and 406 are added.

  Then, by inserting the SD card 2 in which the TOC information image file is recorded into a printer, specifying the label shape and printing, it is possible to easily create an index label of the TOC information (a TOC label of the media). . The printer used at this time does not need to handle the TOC information as binary or text data, and it is sufficient to have a function of printing as an image, which is an advantageous feature of the present embodiment.

  As shown in FIG. 5, the created index label of the TOC information can be attached to the label attaching region 410 of the storage case 409 of the recording medium 1 (optical disc).

<Other display forms of content management information>
6A and 6B are screen views showing other display forms of the content management information according to the present embodiment. FIG. 6A shows the contents of the playlist, and FIG. c) shows the directory (folder) structure of the media in a tree structure.

  Each of the display forms (a) and (b) shows an LCD display corresponding to each display or operation mode of the video camera apparatus shown in FIG. 1, and each of the focus 601 and 611 and the operation buttons 602 and 612. In addition, in the example of FIG. 6A, a thumbnail image 603 is added. Image file generation corresponding to these displays can also be realized by the processing according to the operation flow of FIG.

  6A, the system control circuit 113 extracts the thumbnail image from the “Index01.efg” file 203 reproduced from the recording medium 1 in the configuration of FIG. By rendering the thumbnail image decoded by the still image CODEC circuit 108 in the rendering memory circuit 110 by the rendering circuit 107, rendering combined with the management information becomes possible.

  As described above, according to the present embodiment, complex content management information such as TOC information, playlist information, and folder information of content recorded in the recording medium 1 can be used for label printing of the media 1 and the like. A label print function that can be generated as a file and can be easily printed on a normal printer can be realized.

  As a result, the printer can easily make a label print that can visually explain the management of contents in the entire medium, not just the title and thumbnail print of an image clip. Therefore, in addition to the media case described above, the range of applications such as direct printing on printable disc media and labeling on tape cassettes is extremely wide.

[Second Embodiment]
The digital video camera apparatus shown in FIG. 1 can be connected to a DVD recorder via USB, and the content reproduced from the recording medium 1 on the camera apparatus side can be digitally copied to the recording medium of the DVD recorder. In the second embodiment, when such a configuration is adopted, an image file containing only management information related to the content to be digitally copied can be generated, and an index label can be created from the image file.

  FIG. 7 is a block diagram showing a configuration of a digital video camera apparatus including a playback apparatus according to the second embodiment of the present invention, and arrows in the figure indicate a signal flow during playback.

  The difference from the configuration shown in FIG. 1 is that a transfer path R1 for transferring information necessary for the DVD-Video standard from the system control circuit 113 to the DVD recorder via the USB protocol IF circuit 116, and the recording medium 1 The transfer path R2 for transferring the content information to the DVD recorder side via the recording / reproducing circuit 105 and the USB protocol IF circuit 116 is added. The transfer information passing through the transfer path R1 includes management file information including menu information necessary for the DVD-Video standard.

  First, a main menu screen for selecting content to be copied to the recording medium of the DVD recorder is generated and displayed on the LCD display 112. Specifically, the image data for the main menu screen is created by analyzing the contents of the “Index01.efg” file 203 in the recording medium 1 by the system control circuit 113, and the drawing memory circuit 110 via the drawing circuit 107. And is displayed on the LCD display 112 by the display screen control circuit 109.

  Then, when the user selects information related to the content to be copied to the recording medium of the DVD recorder from the displayed main menu screen, and in this state, uses the operation key 114 to instruct generation of an image file for label printing. Then, the drawing contents of the drawing memory circuit 110 are once erased, and image data including only information relating to the selected contents is drawn in the drawing memory circuit 110. As a result, only the information related to the content selected to be copied to the recording medium of the DVD recorder is displayed on the LCD display 112, and at the same time, the image data of the information is transferred from the drawing memory circuit 110 to the image reading circuit for printing. The data is read by 111, JPEG-compressed by the still image CODEC circuit 108, and then recorded on the recording medium 2 (SD card) as a label printing image file in accordance with the DCF standard.

  By inserting the SD card 2 on which this image file is recorded into the printer, and specifying and printing the label shape, it is possible to easily create an index label on which management information relating to the copied content is printed. It can be attached to a storage case of a recording medium.

  As described above, according to the present embodiment, not only the management information of the recording medium built in the recording / reproducing apparatus, but also the content is copied from the recording / reproducing apparatus to a different recording / reproducing apparatus and recorded as a library medium on another medium. Even in the case of saving, image information such as the title main menu of the library medium to be copied can be converted into an image file such as JPEG by converting it into an image file for label printing, and can be easily printed with a normal printer. .

  In recent years, DVD recorders with built-in HDDs have become widespread, and in many cases, an image captured by a camera by a user is recorded on a DVDR media or the like with a DVD recorder according to the DVD-Video standard, thereby leaving a highly compatible DVD library. Under such circumstances, the above-described functions of the present embodiment are extremely useful.

  In each of the above-described embodiments, the management information image file has been described by JPEG compression. However, for graphic images that do not include image information such as thumbnails, for example, GIF (Graphics Interchange Format) or TIFF (Tagged) is used instead of JPEG. It is a well-known fact that a clear management information image can be obtained by an image compression method such as Image File Format. Therefore, the image compression method of the still image CODEC circuit 108 can be appropriately selected according to the contents of management information drawn in the drawing memory circuit 110, and control in that case is performed by the system control circuit 113. As an image compression format of the still image CODEC circuit 108, for example, a bitmap format (BMP), a JPEG format, a GIF format, a TIFF format, or the like can be used.

  The present invention is not limited to the apparatus of the above-described embodiment, and may be applied to a system constituted by a plurality of devices or an apparatus constituted by one device. A storage medium storing software program codes for realizing the functions of the above-described embodiments is supplied to a system or apparatus, and a computer (or CPU or MPU) of the system or apparatus reads and executes the program codes stored in the storage medium. Needless to say, it will be completed by doing.

  In this case, the program code itself read from the storage medium realizes the functions of the above-described embodiments, and the storage medium storing the program code constitutes the present invention. Examples of the storage medium for supplying the program code include a floppy (registered trademark) disk, a hard disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, a nonvolatile memory card, and a nonvolatile memory. Can be used. Further, by executing the program code read by the computer, not only the functions of the above-described embodiments are realized, but also the OS running on the computer based on the instruction of the program code performs the actual processing.
