In the MPU 2 of FIG. 1, a user interface creating unit 2A, a menu determining unit 2B, and the like are incorporated as firmware, and a data memory (OSD or other use data memory) 2C is provided. Although not shown, the MPU 2 is also provided with a program memory in which other firmware (programs for performing the processes in FIGS. 6 to 11) is written. In the system processor unit 6, a data separation unit 6A and a memory I / F unit 6B are provided.

Further, in the MPU 2, a command detection unit 2P, a capture control unit 2Q,
A storage control unit 2R, an interval control unit 2S, and an observation image output control unit 2T are provided. These operate together during the flash observation operation, and the details thereof will be described later.

The basic flow of data in the configuration shown in FIG. 1 is as follows. That is, the MPU unit 2 sends a target address and a read command to the disk drive unit 5. Then, the disk drive unit 5 reads the target logical sector data from the disk 10 in accordance with the transmitted address and command, and sends the read pack data to the system processor unit 6 through a data input unit (not shown). In the system processor unit 6, the data separation unit 6
A divides the transmitted pack data into packet data, transfers video packet data (MPEG-encoded data) to the video decoder unit 3 according to the content (purpose) of the data, and converts the audio packet data into an audio decoder. The sub video packet data is transferred to the SP decoder unit 8. The navigation pack NV_PCK and other packs (audio pack A_PCK, video pack V_PCK, sub-picture pack S
The header section of P_PCK or the like is transferred to the work memory section 7 via the memory I / F section 6B and stored therein so that the MPU section 2 appropriately processes the header section. Each packet data sent to each decoder section performs a reproduction process in synchronization with a value of a reproduction time stamp (PTS) in the packet data. Thus, for example, a moving image (movie) with English audio and Japanese subtitles can be displayed on the screen of the TV monitor 20.

Inside the MPU 2, an on-screen display (OSD) for providing a user interface for visually operating and confirming by a user is generated using the internal data of the data memory 2C. This generation is performed by firmware called a user interface generation unit 2A, and the generated OSD data is stored in the video memory unit 11. Also, inside MPU2,

-Y coordinate information), auto action mode information indicating a button selection / activation (action) state, and the like.

For example, when a menu screen is reduced and a plurality of menus are simultaneously displayed on one screen, a button operation may be performed from the reduced menu.
In this case, since the actual button position (the mark operated by the user when selecting a menu item) is shifted from the case where the image is not reduced, it is necessary to correct the position data of the button so as to match the reduced menu. The correction of the position data includes the display position of the reduced menu on the screen (for example, the XY coordinate of the upper left corner of the reduced menu display area), the reduction ratio (1/2 or 1/4, etc.), and FIG. This can be performed based on the button position information.

In the DVD video system, a simple language called a navigation command is prepared in order to enhance interactivity. The button command in FIG. 3 is also a kind of navigation command, and when the button is activated (action), the corresponding navigation command is executed. This navigation command is transmitted before and after the reproduction of the program chain, after the reproduction of the cell, after the reproduction of the VOBU, the navigation pack NV_
Each can be performed during the PCK process.

FIG. 4 is a diagram for explaining the types of menu information recorded on the DVD disk of FIG. 2 and the hierarchical structure of the menu used in the DVD player 1 of FIG. This diagram is also a conceptual diagram for explaining the correspondence between the system menu and the user operation functions.

In a DVD player, a title menu and a root menu (main menu) are essential, and the title menu is a video manager menu (V
MGM), and the root menu is handled by a video title set menu (VTSM).

As shown in FIG. 3, the video title set menu has a hierarchical structure composed of a root menu and various lower hierarchical menus. Here, the category (VTSM_PGC_CAT) of the program chain for the video title set menu is configured as follows. That is, although not shown, VT
The lower 8 bits of SM_PGC_CAT are assigned to the lower bits of the parental identification field, the next 8 bits are assigned to the upper bits of the parental identification field, the next 4 bits are reserved as a reserved field, and the next 2 bits specify the block type. The next two bits specify the block mode, the next four bits describe the menu identifier (menu ID), the next three bits are reserved as a reserved field, and the last one bit (the 32nd bit) is the entry type. Is specified.

First, if the first entry type is 1b (binary 1) counting from the upper bit of 4 bytes (32 bits), it indicates that the corresponding program chain (PGC) is an entry PGC, and if it is 0b, the corresponding program chain (PGC) is corresponding. This indicates that the program chain is a program chain other than the entry PGC.

The contents of the subsequent 4-bit menu identifier (menu ID) are determined as follows. If the entry type is 0b, 0000b is entered in the menu ID, and if the entry type is 1b, the following binary code is entered in the menu ID.
That is, 0011b is entered for the root menu, 0100b is entered for the sub-picture menu, 0101b is entered for the audio menu, 0110b is entered for the angle menu, and 0111b is entered for the part of title (such as chapter) menu.
Is entered. Other 4-bit binary codes of menu identifiers (menu IDs) are reserved for other uses.

If the 2-bit block mode following the menu identifier (menu ID) is 00b, it indicates that it is not the program chain in the corresponding block, and if it is 01b, it indicates that it is the first program chain in the corresponding block. If it is 10b, it indicates that it is the program chain in the corresponding block.
If it is b, it indicates that it is the last program chain in the corresponding block. The following 2-bit block type is 0
If it is 0b, it indicates that it is not a part of the corresponding block, and if it is 01b, it indicates that it is a parental block (a block whose reproduction is allowed only under specific conditions). The subsequent 8 + 8 bits are an area in which information (flag bit string) for determining the reproduction condition of the parental block is described.

FIG. 5 is a view for explaining a part of the user operation control information recorded on the DVD disk of FIG. This figure shows the user operation control (UOP0, UOP1) in the title reproduction type TT_PB_TY in FIG. 2, the user operation control (UOP0 to UOP24) in the user operation control PGC_UOP_CTL in FIG. 2, and the user operation control VOBU_UOP_CTL in FIG.

On the front side of the lid 540, a television operation key portion 541 is provided as shown in FIG.

FIG. 15 is a flowchart for explaining the operation in the case of performing the flash observation image processing which is a feature of the present invention.

When performing the strobe observation image processing, the OSD memory 2C, command detection unit 2P, capture control unit 2Q, storage control unit 2R, interval control unit 2S,
The observation image output control unit 2T operates together.

When a command for strobe observation is input (steps F1 and F2), information on the image displayed at that time is taken into the memory as information on the reference image (step F3). The command is detected by the command detection unit 2P in FIG. 1, the capture control unit 2Q operates in response to the command detection, retrieves decoded image information, and controls the storage control unit 2R to, for example, store the decoded image information in the video memory unit 11. Store. Further, the succeeding image information subsequent to the reference image information is fetched, for example, for five screens at a time interval set as normal by the interval control unit 2S in advance, and stored in the video memory unit 11 (step F).
4). Next, the screen area of each image information is reduced based on the control of the storage control unit 2R, and is stored in the video memory unit 11 again (steps F5 and F6). Then, these six images are sent to the TV monitor 20 and displayed based on the control of the observation image output control unit 2T (step F7). The display state is, for example, as shown in FIG.
The information is displayed on one screen of the monitor 20.

To enter the strobe observation state, for example, the user operates the remote controller 500 to move the cursor to “Strobe Viewer” from the menu shown in FIG. It becomes an observation state. The cursor can be moved by operating the cursor control button 512.

The time interval set as normal is, for example, a 1/15 second interval. This interval is not limited to this. Next, it is determined whether a command for adjusting the time interval, that is, a slow (slow) or fast (fast) control command has been input (step F8). This command can be issued, for example, by moving the cursor to the position of the slow display operation image 801 or the first display operation image 802 appearing on the screen of FIG. 16 and pressing the enter key. When the slow display operation image 801 is selected and the enter key is pressed, the reference image is kept as it is, but the interval for taking in the subsequent image information becomes shorter. As a result, the interval for taking in the subsequent image information can be, for example, 1/20 second.
If you press the enter key further, 1/25 second interval, 1/30
The capture interval can be reduced, for example, at intervals of seconds or 1/35 seconds. First display operation image 802
Is selected and the enter key is pressed, the reference image is left as it is, but the interval for taking in the subsequent image information is increased this time. As a result, the capture interval of the subsequent image information can be set to, for example, 1/10 second interval. When the enter key is further pressed, the capture interval can be increased, for example, at 1/5 second intervals, 1 second intervals, and 1.5 second intervals. These time intervals are based on the control of the interval control unit 2S, and the image capture interval (interval) of the capture control unit 2Q.
Is adjusted.

A normal (normal) display operation image 803 also exists on the screen. This normal display operation image 803
When the cursor is moved to and the enter key is pressed, the display state of the screen is changed to the above-described normal setting time interval, while the reference image remains unchanged.

When the above-described operation is performed, the reproducing apparatus reads information from the DVD again. Then, the subsequent image information of the reference image information is read.

Further, as the operation content, there is a next screen request operation image 804 of “>>”, which means a request for the next screen. When the cursor is moved to the position of the next screen request operation image 804 and the enter key is pressed (step F9), the reference image changes. In other words, the reference image is changed, for example, the succeeding image 1 that has been captured next to the reference image until now. There are various methods for selecting which subsequent image is selected as the reference image, and the method is not limited to the above description. Which subsequent image is selected as the next reference image is arbitrary.

When the next screen is requested, the succeeding image information is fetched from the new reference image information.
In this case, for example, the capture is performed at normal intervals (step F10). Then, the video memory unit 11
The old image information is shifted or cleared, and the image information for six new screens is stored in the video memory unit 1.
1 is stored. Then, this image information is displayed (step F11).

When the next screen request operation image 804 is selected, the present invention is not limited to the image processing as described above. For example, the time interval of the captured image information may be maintained such that the currently set interval is maintained, and the screen on the TV monitor 20 is moved up by one screen each time the enter key is pressed. In this case, as the newly acquired image information, new image information corresponding to the temporally last succeeding image 5 may be acquired, compressed, and written in the memory unit 11. For other images, the image in the memory unit 11 may be shifted.

On the screen, the “Navi” operation image 80
5. An “Exit” operation image 806 exists. “Nav
When the cursor is positioned on the “i” operation image 805 and the enter key is operated, the menu screen shown in FIG. 13 can be returned. Also, the cursor is positioned on the “Exit” operation image 806 and the enter key is operated. Then (step F13), it is determined whether or not the normal operation has been performed (step F14) .If the normal operation has not been performed, the process ends, and if the normal operation has been performed,
It returns to step F4.

In addition, on the screen, a status screen 807 indicating that the current state is the strobe observation state is also displayed.

FIG. 17 shows a part of the management information recorded on the DVD.

To realize the above-described strobe observation image processing, the reproducing apparatus refers to the disc management information and
Capture of image information must be realized. Therefore, for example, the information shown in FIG. 17 is used as an example. This management information is stored in the navigation pack (N
V_PCK) in the DSI data. DSI

Although not shown, the general information of the DSI includes its own V
The end address of the OBU is described.

Therefore, by reading and managing such information, it is possible to recognize the VOBU address that is currently being reproduced, and also to recognize the start address of the VOBU before and after that. In FIG. 17, the start address of the VOBU 240 places ahead of the next UOBU and the previous VOBU
From the start address of the VOB before 240.

FIG. 18 is a diagram for explaining how to manage a frame or a field (hereinafter, representatively described as a frame) output from the decoder unit 3. The capture control unit 2Q holds the current start address of the VOBU received from the NV pack management unit 2U,
Further, it recognizes what number of image information in the VOBU the field or frame currently output from the decoder unit 3 is. When there is a strobe observation request, the capture control unit 2Q captures the current frame (image information) as reference image information, and the storage control unit 2R stores it in the video memory 11. The capture control unit 2Q stores the frame number at this time. Further, the capture control unit 2Q
Based on the interval (time interval) information provided from the interval control unit 2S, it is determined how many subsequent images after the reference image should be taken. At first, image information is taken in at predetermined normal intervals. As a result, the subsequent image is stored in the video memory 11. Next, the storage control unit 2R reduces the area of each image captured in the video memory unit 11 and stores the reduced image in the video memory 11 again. When a strobe observation command is received, the storage control unit 2 </ b> R may reduce the reference image information and the subsequent image information from the beginning and store them in the video memory unit 11.

As described with reference to FIG. 15, when there is a slow or fast operation (step F8), the interval control unit 2
S changes the interval information. Then, the capture control unit 2Q determines the frame interval of the captured image according to the interval. Then, the capture control unit 2Q gives the start address of the current VOBU to the read control unit (not shown) of the playback device. Then, the playback device plays back the video data from the beginning of the current VOBU. Next, when the image information of the stored frame number is reproduced, the capturing control unit 2Q starts capturing. Then, subsequent image information is taken in according to the designated interval. The captured image information is reduced and stored in the video memory unit 11 under the control of the storage control unit 2R. Then, the stored image information is displayed on the TV monitor 20 under the control of the observation image output control unit 2T.

Note that a VOBU has a plurality of VOBUs in a DVD because the image is compressed for 0.4 to 1.5 seconds.
There is a case where image information is taken in over a U frame. Therefore, the management of the start address of the VOBU is as follows.
The head addresses of a plurality of VOBUs can be managed.

In the above embodiment, the start address of the VOBU and the frame number (or field number)
And the interval information was managed to determine the image information to be captured. However, the present invention is not limited to this, and may be managed by time information.

That is, when the time measurement counter is used to capture the subsequent image information after the reference image information, the succeeding image information to be captured may be determined based on the count value of the time measurement counter. That is, when determining the frame interval of the image information to be captured, the frame interval is determined based on the interval time information provided from the interval control unit 2S.

The moving images suitable for flash observation include a golf swing scene, a short-range (100 m) goal scene, a swimming goal scene, a baseball stolen baseball and touch cross-spray in baseball, and the like.

In the above description, the strobe observation has been described. However, this function can be easily modified as an angle viewer. In a DVD, scene information obtained by photographing a subject from different angles is compressed and packetized, and each scene is divided, interleaved, and recorded. In the reproducing apparatus, any one scene is seamlessly and continuously reproduced according to a user selection. The control information for realizing the seamless reproduction is recorded as the seamless reproduction information and the seamless angle information of the DSI in FIG. The DVD is divided into a maximum of nine angle scenes, and the divided interlibrary units are recorded by interleaving each scene.

Therefore, when confirming what kind of content is recorded as the angle scene, only slightly changing the image processing function described above, for example, six scenes of the multi-angle are displayed side by side on the screen. It is also possible.

For example, when a desired image is displayed, the angle button is operated. Then, a desired image is displayed, for example, at the position of the reference image. Then, the image of another corresponding angle is displayed at the position of the subsequent image. In the example of the screen shown in FIG. 16, images for six angles are displayed. However, if there is an angle screen, another angle image is displayed by pressing the jog button 514 or the cursor control button. be able to. In this case, the circuit block shown in FIG. 18 takes in the image information of each angle into the video memory 11.

When the reproduction of the place where the multi-angle scene is recorded is started, the UOP 22 shown in FIG. 5 becomes “user operation of angle switching = permission”. Then,
The angle button or the “Angle” icon becomes operable. When operation is not possible, there is no response even if the angle button is operated, or "Angl
The “e” icon is shaded, for example, indicating that there is no response when operated.

As described above, according to the present invention, a moving image stream can be intermittently extracted and displayed, and the extraction interval can be arbitrarily changed. It is possible to provide a strobe observation image processing device effective for analysis and the like.
