Determine.

  If it is determined in step S11 that the image data in units of frames from the NTSC / PAL encoder 80 is not multi-angle image data, steps S12 to S17 are skipped and the process proceeds to step S18.

  On the other hand, if it is determined in step S11 that the image data in units of frames from the NTSC / PAL encoder 80 is multi-angle image data, the process proceeds to step S12, and the assignment unit 123 has already set the image display device 11 as a display target. It is determined whether or not a display form has been assigned, that is, whether or not the image data has been determined to be multi-angle image data prior to the immediately preceding step S11.

  In step S12, when it is determined by the assigning unit 123 that the display target and the display form have already been assigned to the image display device 11, that is, before the processing of the immediately preceding step S11, the image data is multi-angle image data. If it is determined, steps S13 to S16 are skipped and the process proceeds to step S17.

  On the other hand, when it is determined in step S12 that the display unit and the display form are not already assigned to the image display device 11 by the assigning unit 123, that is, before the processing of the previous step S111, the image data is multi-angle image data. If it is not determined that there is, the multi-angle determination unit 121 supplies the determination result determined in step S11 to the angle number detection unit 122, and the process proceeds to step S13.

  In step S <b> 13, the angle number acquisition unit 122 acquires the angle number K of multi-angle image data that is image data in units of frames from the NTSC / PAL encoder 80, and supplies it to the allocation unit 123 and the index image creation unit 124.

  Specifically, for example, when the image data is multi-angle image data, the image data includes data indicating the number of angles K of the multi-angle image data in addition to data indicating whether the image data is multi-angle image data. The angle number acquiring unit 122 extracts the angle number K by extracting the data indicating the angle number K added to the multi-angle image data, and acquires the angle number K, and sends it to the assigning unit 123 and the index image creating unit 124. Supply.

  After the processing in step S13, the process proceeds to step S14, and the allocating unit 123 transmits the K-angle multi-angle image data to each image display device 11 based on the angle number K from the angle number acquiring unit 122. One of them is assigned as a display object, and a display form of the display object is assigned.

  For example, when the angle number K from the angle number acquisition unit 122 is 5, the allocating unit 123 includes five image display devices 11-7 to 11-9, 11-6, and 11-3. Multi-angle image data of angles # 1 to # 5 is assigned as a display object, a moving image is assigned as a display form of angle # 1, and a still image is assigned as a display form of angles # 2 to # 5. Then, the assigning unit 123 assigns the multi-angle image data of the angle # 1 to which the moving image is assigned as the display form to the remaining four image display devices 11-1, 11-2, 11-4, and 11-5. Assigned as a display object, and “zoom four-division (display of 1/4 of enlarged (zoomed) moving image)” is assigned as the display form.

  As described above, the assigning unit 123 assigns each image display device 11 based on the angle number K. For example, when the number of angles K is smaller than the number of the image display devices 11, the assigning unit 123 assigns each angle image to the K image display devices 11 as a display target, and displays “moving image” as one angle display form. “Display” is assigned, and “Still image display” is assigned as the display mode of other angles. Then, the assigning unit 123 assigns the image of the display target angle assigned with “moving image display” as the display form to the remaining image display devices 11 other than the K image display devices 11, and displays the display target image. “Zoom display” is assigned as the target display form. Thus, the remaining image display device 11 other than the number K of angles can be used for zoom display of a multi-angle image at a certain angle without leaving any remaining. That is, a multi-angle image can be efficiently displayed on the image display device 11.

  After the processing in step S14, the process proceeds to step S15, and the allocation unit 123 supplies allocation information representing the result allocated in step S14 to the memory 84 and stores it as a table (FIG. 8), and displays the allocation information as an image. The device 11 is supplied and the process proceeds to step S16.

  In step S16, the index image creation unit 124 performs an index image creation process for creating an index image. Details of the index image creation processing will be described later with reference to the flowchart of FIG. After the process of step S16, the process proceeds to step S17.

  In step S <b> 17, the read control unit 125 performs a read control process for controlling reading of image data recorded on the optical disc 31. Details of this read control processing will be described later with reference to the flowchart of FIG. After the process of step S17, the process proceeds to step S18.

  In step S18, the servo DSP 75 controls the optical pickup 72 under the control of the read control unit 125, and reads the image data at the read position determined in the process of step S17. At this time, the read position has moved to the last position of the read image data (the first position of the next image data (the start position of the next frame)). After the process of step S18, it returns to step S11 and repeats the process mentioned above.

  FIG. 10 is a flowchart for explaining the index image creation processing in step S16 of FIG.

  In step S31, the index image creation unit 124 sets a count value A of a counter (not shown) to 1, and proceeds to step S32. In step S32, the index image creation unit 124 determines whether the count value A is equal to or less than the number K of angles supplied from the angle number acquisition unit 122 in step S13 in FIG.

  If it is determined in step S32 that the count value A is equal to or less than the number of angles K, the process proceeds to step S33, where the index image creation unit 124 reads the first (first) multi-angle image data of the angle #A. The control signal is supplied to the read control unit 125. Based on the control signal, the read control unit 125 determines the read position as the position of the first multi-angle image data of the angle #A with respect to the optical disc 31, and supplies a control signal indicating the read position to the servo DSP 75. To do. The servo DSP 75 controls the optical pickup 72 based on the read position represented by the control signal from the read control unit 125, and reads (reproduces) the first multi-angle image data of the angle #A. As a result of the reproduction, the first multi-angle image data of angle #A is output to the image display device 11 via the RF amplifier 73, demodulator 74, ECC unit 76, AV decoder 78, and NTSC / PAL encoder 80. The

  After the processing in step S33, the process proceeds to step S34, and the index image creation unit 124 supplies the image display device 11 with an index signal that instructs writing of the multi-angle image data of angle #A into the memory 142.

  When the index signal is supplied from the index image creating unit 124, the multi-angle image data of the angle #A of the frame unit from the NTSC / PAL encoder 80 is obtained from the allocation information supplied from the allocation unit 123 in step S15 of FIG. When it is determined that the image data is multi-angle image data assigned to its own display target, the image processing unit 141 of the image display device 11 performs image processing such as IP conversion, and multi-angle image data after image processing. Is stored in the memory 142.

  For example, when the count value A is 1 and the allocation information represented by the table shown in FIG. 8 is supplied from the allocation unit 123, the ID number to which the multi-angle image data with the angle number “1” is allocated as the display target. 1, 11, 11-2, 11-4, 11-5, and 11-7 have image processing units 141 that receive frames from the NTSC / PAL encoder 80. Image processing is performed on the unit image data and stored in the memory 142.

  Note that the image display devices 11-1, 11-2, 11-4, and 11-5 to which the zoom display is assigned as the display form do not store the multi-angle image data of the angle # 1 in the memory 142, and the display form. Only the image display device 11-7 to which the moving image display is assigned can perform image processing on the multi-angle image data of the angle # 1 and store it in the memory 142.

  After the process of step S34, the process proceeds to step S35, the count value A is incremented by 1, and the process returns to step S32.

  In step S32, the count value A is not less than the number of angles K, that is, the multi-angle image data of all angles is assigned to the multi-angle image data of that angle as the display target. When the data is stored in the memory 142, the process proceeds to step S36, and the index image creation unit 124 controls the read control unit 125 to determine the read position as the position of the first multi-angle image data of angle # 1 with respect to the optical disc 31. Supply the signal. Based on the control signal, the read control unit 125 determines the read position as the position of the first multi-angle image data of the angle # 1 with respect to the optical disc 31.

  After step S36, the process proceeds to step S37, and the index image creation unit 124 reads the table from the memory 84. Based on the allocation information represented by the table, the index image creating unit 124 sends the multi-angle image data from the memory 142 or the multi-angle image data from the image processing unit 141 to each image display device 11 (the output selection unit 143). An index signal is supplied to command one of the outputs.

  For example, when the index image creating unit 124 reads the table shown in FIG. 8 from the memory 84, the image display devices 11-1, 11-2, 11-4, 11 assigned the angle number “1” as the display target. -5 and 11-7 are supplied with an index signal for instructing output of multi-angle image data from the image processing unit 141. Further, the index image creation unit 124 multi-angles from the memory 142 to the image display devices 11-3, 11-6, 11-8, and 11-9 to which an angle number other than “1” is assigned as a display target. An index signal for instructing output of image data is supplied.

  At this time, the output selection unit 143 of the image display device 11 outputs the multi-angle image data from the memory 142 or the image processing unit 141 to the display 144 based on the index signal. The display 144 displays a multi-angle image based on the multi-angle image data from the output selection unit 143.

  After step S37, the process returns to step S16 in FIG. 9 and proceeds to step S17.

  FIG. 11 is a flowchart illustrating the read control process in step S17 of FIG.

  In step S51, the read control unit 125 acquires an offset that is the reproduction time of the multi-angle image corresponding to the read position. Specifically, for example, on the optical disc 31, a table (hereinafter referred to as a correspondence relationship) between a reproduction time of a recorded multi-angle image and a position with respect to the optical disc 31 on which the multi-angle image (data) is recorded. A time position table) is recorded. The read control unit 25 acquires the reproduction time corresponding to the read position as an offset based on the recorded time position table.

  In step S <b> 52, has the read control unit 125 supplied from the light receiving unit 21 a control command (hereinafter referred to as a moving image switching command) that specifies the image display device 11 that changes the assigned display form to “moving image display”? Determine if.

  Specifically, for example, while viewing the image display device 11 shown in FIG. 7, the user displays a multi-angle image of a desired angle in order to instruct a change in the angle of the multi-angle image displayed as a moving image. The number key of the remote controller 13 assigned with the ID number of the image display device 11 is operated. For example, when the multi-angle image of the user's desired angle is a multi-angle image of angle # 2, the ID number “8” of the image display device 11-8 on which the multi-angle image of angle # 2 is displayed is attached. The number key of the remote controller 13 is operated.

  The remote controller 13 transmits a moving image switching command for designating the image display device 11-8 to change the assigned display form to “moving image display” in accordance with the operation of the number key from the user. The moving image switching command is received and supplied to the read control unit 125. That is, the light receiving unit 21 instructs the read control unit 125 to change the angle of the multi-angle image displayed as a moving image.

  If it is determined in step S52 that the moving image switching command is not supplied from the light receiving unit 21, steps S53 and S54 are skipped, the process returns to step S17 in FIG. 9, and the process proceeds to step S18.

  On the other hand, when it is determined in step S52 that the moving image switching command is supplied from the light receiving unit 21, the process proceeds to step S53, and the read control unit 125 reads the table from the memory 84. Then, the read control unit 125 recognizes the angle number associated with the ID number of the image display device 11 specified by the moving image switching command. Further, the read control unit 125 corresponds to the offset (reproduction time) acquired in step S51 of the multi-angle image (data) of the angle of the recognized angle number based on the time position table recorded on the optical disc 31. The position is determined with respect to the optical disc 31 (the position advanced by the offset from the position of the head multi-angle image data).

  In step S53, the read control unit 125 determines the position relative to the optical disc 31 corresponding to the offset acquired in step S51 as the read position, so that it is synchronized with the multi-angle image displayed as a moving image when the moving image switching command is supplied. Thus, a moving image of a multi-angle image corresponding to the moving image switching command can be displayed. That is, when the user operates the remote controller 13 to instruct the change of the angle of the multi-angle image displayed as a moving image, the multi-angle image displayed on the moving image and the reproduction time when the remote controller 13 is operated. Can display a multi-angle image of the angle at which the change is commanded at the same time.

  After the process of step S53, in step S54, the read control unit 125 changes the table stored in the memory 84 based on the moving image switching command from the light receiving unit 21. For example, when the table shown in FIG. 8 is stored in the memory 84 and the moving image switching command designates the image display device 11-8 with the ID number “8”, the read control unit 125 sets the angle number “1”. "And the angle number corresponding to the ID numbers 1, 2, 4, and 5 associated with the display form" zoom 4 division "are changed from" 1 "to" 2. " As a result, the moving image of the multi-angle image of angle # 2 is zoomed and the image display devices 11-1, 11-2, 11-4, and 11- whose ID numbers are 1, 2, 4, and 5 are displayed. 5 is displayed.

  Further, the read control unit 125 changes the display form corresponding to the ID number “7” associated with the angle number “1” and the display form “index (moving picture)” from “index (moving picture)” to “ Change to "Index (still image)". Further, the read control unit 125 changes the display form corresponding to the ID number “8” from “index (still image)” to “index (moving image)”.

  And after the process of step S54, it returns to step S17 of FIG. 9, and progresses to step S18.

  FIG. 12 is a flowchart illustrating the image processing of the image processing unit 141 in FIG. This image processing is started when the NTSC / PAL encoder 80 of FIG. 4 or multi-angle image data is supplied, and is performed for each frame, for example. Note that the image processing of FIG. 12 is processing performed when an index signal is not supplied from the indexed image creation unit 124.

  In step S71, the image processing unit 141 determines whether the display form assigned to itself is zoom display based on the assignment information from the assigning unit 123 (FIG. 5) of the disc playback apparatus 12. For example, when the allocation information represented by the table shown in FIG. 8 is supplied from the allocation unit 123, the image processing unit 141 of the image processing apparatus 11-1 having the ID number “1” is allocated to itself. It is determined that the display form is zoom display.

  If it is determined in step S71 that the display form assigned to itself is zoom display, the process proceeds to step S72, and the image processing unit 141 determines the zoom range based on the assignment information from the assignment unit 123. To do. For example, when the display form assigned to itself is “zoom quadrant (upper left)”, the zoom range is an upper left area obtained by dividing the multi-angle image into four.

  After step S72, the process proceeds to step S73, and the image processing unit 141 performs zoom processing on the multi-angle image data according to the zoom range determined in step S72. For example, when the display form assigned to itself is “zoom quadruple (upper left)”, the multiangle image data corresponding to the upper left area obtained by dividing the multiangle image into four is zoomed (enlarged) four times. Is done.

  After the processing in step S73, the process proceeds to step S74, and the image processing unit 141 performs IP conversion on the multi-angle image data zoomed in step S73, supplies the converted data to the output selection unit 143, and ends the processing. To do.

  On the other hand, when it is determined in step S71 that the display form assigned to itself is not zoom display, the process proceeds to step S75, and the image processing unit 141 is in a moving image mode in which a moving image is displayed. Determine if it exists. When the first image data (image data of the first frame) is supplied, if the display form assigned to itself is a moving image based on the assignment information from the assignment unit 123, The mode is determined to be the movie mode.

  If it is determined in step S75 that the own mode is a moving image, the process proceeds to step S76, and the image processing unit 141 determines whether to switch the own mode to the still image mode. Specifically, the image processing unit 141 determines whether a moving image switching command for designating an image display device 11 other than itself is supplied from the light receiving unit 21. In step S76, when it is determined that the own mode is switched to the still image mode, that is, when it is determined that the moving image switching command for designating the image display device 11 other than the own is supplied from the light receiving unit 21, In step S77, the image processing unit 141 changes its own mode to a still image mode for displaying a still image.

  After the process of step S77, the process proceeds to step S78, and the image processing unit 141 performs IP conversion on the multi-angle image data in units of frames from the NTSC / PAL encoder 80, and the process proceeds to step S79. In step S79, the image processing unit 141 supplies the multi-angle image data after the IP conversion to the memory 142, stores it, and ends the process. The memory 142 supplies the stored image data to the output selection unit 143.

  On the other hand, when it is determined in step S76 that the own mode is not switched to the still image mode, that is, it is determined that the moving image switching command for designating the image display device 11 other than the own is not supplied from the light receiving unit 21. If YES, go to step S82.

  When it is determined in step S75 that the own mode is not the moving image mode, the process proceeds to step S80, and the image processing unit 141 determines whether to switch the own mode to the moving image mode. Specifically, the image processing unit 141 determines whether or not a moving image switching command for designating its own image display device 11 is supplied from the light receiving unit 21. If it is determined in step S80 that the own mode is to be switched to the moving image mode, that is, if a moving image switching command for designating the own image display device 11 is supplied from the light receiving unit 21, the process proceeds to step S81.

  In step S81, the image processing unit 141 changes its own mode to the moving image mode, and the process proceeds to step S82. If it is determined in step S80 that the own mode is not switched to the moving image mode, that is, if the moving image switching command for designating the own image display device 11 is not supplied from the light receiving unit 21, the process proceeds to step S82.

  In step S82, the image processing unit 141 performs IP conversion on the image data in units of frames from the NTSC / PAL encoder 80, supplies it to the output selection unit 143, and ends the processing.

  In FIG. 12, the image processing performed by the image processing unit 141 when multi-angle image data is supplied from the NTSC / PAL encoder 80 has been described. However, when normal image data is supplied from the NTSC / PAL encoder 80, FIG. For example, the image processing unit 141 divides the moving image of the normal image data into nine parts, zooms the nine divided moving images, and displays them on the nine image display devices 11 respectively, in step S71 of FIG. To S74. At this time, the output selection unit 143 outputs the normal image data from the image processing unit 141 to the display 144 to display the normal image.

  FIG. 13 is a flowchart for explaining output selection processing performed by the output selection unit 143 of FIG. This output selection process is started, for example, when multi-angle image data is supplied from the image processing unit 141 or the memory 142.

  In step S91, the output selection unit 143 determines whether to output the multi-angle image data from the image processing unit 141. For example, when an index signal is supplied from the index image creation unit 124 (FIG. 5) in step S37 in FIG. 10, the output selection unit 143 determines whether the index signal represents the image processing unit 141. In addition, when the moving image switching command is supplied from the light receiving unit 21, the output selection unit 143 determines whether the image display device 11 specified by the moving image switching command is itself based on the allocation information from the allocation unit 123. If it is itself, it is determined that the image data from the image processing unit 141 is output. On the other hand, when it is determined that the image display device 11 specified by the moving image switching command is not itself, it is determined that the image data from the image processing unit 141 is not output.

  If it is determined in step S91 that the multi-angle image data from the image processing unit 141 is to be output, the output selection unit 143 selects the multi-angle image data from the image processing unit 141, and the process proceeds to step S94.

  If it is determined in step S91 that the multi-angle image data from the image processing unit 141 is not output, the process proceeds to step S93, and the output selection unit 143 selects the multi-angle image data from the memory 142, and step S94. Proceed to

  In step S94, the output selection unit 143 outputs the multi-angle image data selected in step S92 or S93 to the display 144, and ends the process. The display 144 displays an image based on the multi-angle image data from the output selection unit 143.

  After the multi-angle image data from the NTSC / PAL encoder 80 is supplied to the angle number detection unit 182, the next time the multi-angle image data to which the same angle mark as the angle mark of the template is added is supplied. The number of frames N of the multi-angle image data supplied from the NTSC / PAL encoder 80 is detected, and the number of frames N is acquired as the number of angles. The angle number detection unit 182 supplies the angle number N to the assignment unit 183 and the index image creation unit 184.

  Further, the angle number detection unit 182 instructs the read control unit 185 to output an angle switching command for switching the angle of the image data reproduced by the DVD player 164.

  When the image (data) 191 is supplied from the NTSC / PAL encoder 80 in FIG. 15, the multi-angle determination unit 181 does not add an angle mark to the image 191, so the image supplied from the NTSC / PAL encoder 80. It is determined that 191 (data) is normal image data.

  Thereafter, the read control unit 185 in FIG. 16 supplies an angle switching command to the system controller 171 in FIG. 15 and controls the servo DSP 75 via the system controller 171 to reproduce image data having different angles.

  As a result of the reproduction, when the image (data) 192 with the angle mark 221 added is supplied from the NTSC / PAL encoder 80, the multi-angle determination unit 181 receives the image 192 (data) supplied from the NTSC / PAL encoder 80. ) Is determined to be multi-angle image data.

  On the other hand, when an image (data) 193 without an angle mark is supplied from the NTSC / PAL encoder 80 as a result of reproduction, the multi-angle determination unit 181 adds an angle mark to the image 193 (data). Therefore, it is determined that the image 193 (data) supplied from the NTSC / PAL encoder 80 is normal image data.

  FIG. 18 is a diagram for explaining angle number detection processing of the angle number detection unit 182 of FIG.

  When the multi-angle image (data) 211 to which the angle mark 221 is added is supplied from the NTSC / PAL encoder 80, the angle number detection unit 182 supplies the angle mark 221 to the storage unit 186 and stores it as a template.

  Thereafter, the angle number detection unit 182 instructs the read control unit 185 (FIG. 16) to output an angle switching command. The read control unit 185 supplies an angle switching command to the system controller 171 in FIG. 15 according to a command from the angle number detection unit 182, controls the servo DSP 75 via the system controller 171, and multi-angle images of different angles ( Data) 212 is reproduced.

  Then, the angle number detection unit 182 extracts the angle mark 222 added to the multi-angle image 212 supplied from the NTSC / PAL encoder 80. The angle number detection unit 182 reads the angle mark 221 as a template from the storage unit 186 and compares it with the extracted angle mark 222. Here, the angle marks 221 and 222 are different.

  Since the angle marks 221 and 222 are different, the angle number detection unit 182 further instructs the read control unit 185 to output an angle switching command. Thereafter, as in the case described above, the angle number detection unit 182 performs NTSC until the angle mark added to the multi-angle image data supplied from the NTSC / PAL encoder 80 is the same as the angle mark 221 that is a template. The process of comparing the angle mark added to the multi-angle image (data) supplied from the / PAL encoder 80 with the angle mark 221 is repeated.

  Here, it is assumed that the angle mark 224 added to the multi-angle image 214 supplied from the NTSC / PAL encoder 80 is the same as the angle mark 221. Since the angle mark 224 added to the multi-angle image (data) 214 supplied from the NTSC / PAL encoder 80 and the angle mark 221 read from the storage unit 186 are the same, the angle number detection unit 182 has the same NTSC. The process of comparing the angle mark added to the multi-angle image (data) supplied from the / PAL encoder 80 with the angle mark 221 is terminated.

  The angle number detection unit 182 receives an angle mark 224 that is the same as the angle mark 221 after the multi-angle image 211 to which the angle mark 221 stored in the storage unit 186 as a template is added is supplied from the NTSC / PAL encoder 80. The number N of frames of the multi-angle image supplied from the NTSC / PAL encoder 80 until the added multi-angle image 214 is supplied from the NTSC / PAL encoder 80 (N = 3 in the example of FIG. 18). Is detected as the number of angles.

  FIG. 19 and FIG. 20 are diagrams illustrating an assignment process in which the assigning unit 183 assigns a display target and a display form to each image display device 11.

  A black image 231 shown in FIG. 19 is stored as a template in the storage unit 186 of FIG. The black image 231 includes a black area 241 other than the area corresponding to the 16: 9 aspect ratio area, and a black area 242 corresponding to the 16: 9 aspect ratio area.

  The assigning unit 183 reads the black image 231 that is a template from the storage unit 186. The allocating unit 183 compares the luminance of the image 232 (input image) supplied from the NTSC / PAL encoder 80 and the black image 231, and when the luminance difference of the area 241 is large, the image 232 has an aspect ratio of 4: 3. It is determined that the image is a ratio image. On the other hand, when the difference in luminance in the region 242 is small, the image 232 is determined to be an image having an aspect ratio of 16: 9. However, when the difference in luminance of the region 242 is small, the assignment unit 183 determines that the image 232 is not an image having an aspect ratio of 4: 3 or 16: 9, and performs error processing, for example.

  When determining that the image 232 is an image having an aspect ratio of 16: 9, the assigning unit 183 sets the image display device 11 to which zoom display is assigned as a display form as the image display device 11 that is arranged horizontally.

  In this way, when the display target and the display form are assigned to the assigning unit 183, the multi-angle image shown in FIG. In FIG. 12, the number of angles of the multi-angle image is 3, and a moving image of the multi-angle image of angle # 1 and a still image of the multi-angle image of angles # 2 and # 3 are displayed.

  In FIG. 20, the multi-angle image of angle # 1 is assigned to the image display devices 11-1 to 11-6 arranged horizontally by the assigning unit 183, and zoom display is assigned as the display form. That is, as shown in FIG. 20, on the image display devices 11-1 to 11-6, the 1/6 area of the enlarged moving image of the angle # 1 is displayed.

  The assigning unit 183 assigns the multi-angle image of angle # 1 as the display target and the moving image display as the display form to the image display device 11-7. That is, a moving image of a multi-angle image of angle # 1 is displayed on the image display device 11-1.

  In addition, the assigning unit 183 has a multi-angle image of angle # 2 as a display target on the image display device 11-8, and a multi-angle image of angle # 3 as a display target on the image display device 11-9. Assigned. Further, the assigning unit 183 assigns still image display to the image display devices 11-8 and 11-9 as display modes. That is, the still image of the multi-angle image of angle # 2 is displayed on the image display device 11-8, and the still image of the multi-angle image of angle # 3 is displayed on the image display device 11-9.

  FIG. 21 is a flowchart illustrating a control process in which the control unit 162 in FIG. 16 controls the reproduction of the optical disc 31. This control process is started when image data from the DVD player 164 (NTSC / PAL encoder 80) is supplied to the multi-angle determination unit 181 (FIG. 16).

  In step S <b> 11, the multi-angle determination unit 181 determines whether the image data in units of frames from the NTSC / PAL encoder 80 is multi-angle image data. Specifically, the multi-angle determination unit 181 determines whether or not an angle mark is added to the frame-unit image data from the NTSC / PAL encoder 80. For example, when the image (data) 192 of FIG. 17 is supplied from the NTSC / PAL encoder 80, since the angle mark 221 is added to the image 192, the multi-angle determination unit 181 determines that the image (data) 192 is The multi-angle image data is determined. On the other hand, when the image (data) 193 in FIG. 17 is supplied from the NTSC / PAL encoder 80, since the angle mark is not added to the image (data) 193, the multi-angle determination unit 181 performs the image (data). ) 193 is determined not to be multi-angle image data (normal image data).

  If it is determined in step S111 that the image data in units of frames from the NTSC / PAL encoder 80 is multi-angle image data, the process proceeds to step S112, where the multi-angle determination unit 121 has already been assigned to the image display device by the allocation unit 183. 11, whether a display target and a display form are assigned, that is, whether or not the image data in units of frames from the NTSC / PAL encoder 80 is determined to be multi-angle image data before the immediately preceding step S111. To do.

  In step S112, when it is determined by the assigning unit 183 that the display target and the display form have already been assigned to the image display apparatus 11, that is, before the immediately preceding step S111, the image data from the NTSC / PAL encoder 80 is If it is determined that the image data is angle image data, steps S113 to S117 are skipped and the process proceeds to step S118.

  On the other hand, if it is determined in step S112 that the assigning unit 183 has not already assigned a display target and a display form to the image display device 11, that is, before the immediately preceding step S111, the image data from the NTSC / PAL encoder 80 is obtained. If it is not determined that the image data is multi-angle image data, the multi-angle determination unit 181 supplies the determination result determined in step S111 to the angle number detection unit 182 and proceeds to step S113.

  In step S <b> 113, the angle number detection unit 182 performs angle number detection processing for detecting the angle number N of multi-angle image data that is image data in units of frames from the NTSC / PAL encoder 80. Details of the angle number detection processing will be described later with reference to the flowchart of FIG.

  After the process of step S113, the process proceeds to step S114, and the allocation unit 183 determines the size (aspect ratio) of the multi-angle image (data) based on the multi-angle image data in units of frames from the NTSC / PAL encoder 80. Perform image size determination processing. Details of the image size determination processing will be described later with reference to the flowchart of FIG.

  After the process of step S114, the process proceeds to step S115, and the assigning unit 183 determines each image display device based on the number of angles N from the angle number detection unit 182 and the image size (aspect ratio) determined in step S114. 11 is assigned a display target and a display form of the display target.

  As described above, the allocation unit 183 performs allocation to each image display device 11 based not only on the number of angles N but also on the image size. Therefore, when the multi-angle image is an image having an aspect ratio of 16: 9, for example, as described with reference to FIG. 20, the allocating unit 183 causes the image display device 11 arranged horizontally to Can be assigned to an enlarged display. Thereby, it is possible to optimally assign the multi-angle image to the image display device 11.

  After the process of step S115, the process proceeds to step S116, and the allocation unit 183 stores the allocation information representing the result allocated in step S115 in the storage unit 186 as a table (FIG. 8), and the process proceeds to step S117.

  In step S117, the index image creation unit 124 performs an index image creation process for creating an index image. Details of the index image creation processing will be described later with reference to the flowchart of FIG. After the process of step S117, the process proceeds to step S118.

  In step S <b> 118, the read control unit 125 performs a read control process for controlling reading of image data stored on the optical disc 31. Details of this read control processing will be described later with reference to the flowchart of FIG. After the process of step S118, the process returns to step S111 and the above-described process is repeated.

  If it is determined in step S111 that the frame unit image data from the NTSC / PAL encoder 80 is not multi-angle image data, the process advances to step S119, and the read control unit 185 sends an angle switch command to the system controller 171. Supply. The system controller 171 controls the servo DSP 75 based on the angle switching command, and reads the image data of the next frame.

  FIG. 22 is a flowchart illustrating the angle detection process in step S113 of FIG.

  In step S131, the angle number detection unit 182 stores the angle mark added to the multi-angle image (data) supplied from the NTSC / PAL encoder 80 in the storage unit 186 as a template. For example, the angle number detection unit 182 stores the angle mark 221 of the multi-angle image (data) 211 of FIG. 18 in the storage unit 186 as a template.

  In step S132, the angle number detection unit 182 sets the frame number N to 1, and proceeds to step S133. In step S133, the angle number detection unit 182 causes the read control unit 185 to output an angle switching command. At this time, the read control unit 185 supplies an angle switching command to the system controller 171 (FIG. 15), controls the servo DSP 75 via the system controller 41, and reproduces multi-angle images of different angles. As a result of the reproduction, the angle number detector 182 is supplied with multi-angle image data having an angle different from the multi-angle image data supplied from the NTSC / PAL encoder 80 immediately before.

  After the process of step S133, the process proceeds to step S134, and the angle number detection unit 182 detects an angle mark added to the multi-angle image (data) from the multi-angle image data supplied in step S133. For example, the angle number detection unit 182 detects an angle mark 222 added to the multi-angle image (data) 212 of FIG.

  After the process of step S134, the process proceeds to step S135, and the angle number detection unit 182 reads the template angle mark 221 stored in step S131 from the storage unit 186, and detects the angle mark 221 and the step S134. The angle mark is compared, the difference is extracted, and the process proceeds to step S136.

  In step S136, the angle number detection unit 182 determines whether the difference between the angle mark 221 of the template and the angle mark extracted in step S135 is small, and if it is determined that the difference is not small, The process proceeds to S137. For example, if the angle mark detected in step S134 is the angle mark 222 in FIG. 18, the difference between the angle marks 221 and 222 is large because it is different from the angle mark 221 stored in the storage unit 186 as a template. Yes (not small).

  In step S137, the angle number detection unit 182 increments the frame number N by 1, returns to step S133, and repeats the above-described processing.

  On the other hand, if it is determined in step S136 that the difference between the angle mark 221 of the template and the angle mark extracted in step S135 is small, that is, the angle 211 of the template and the angle mark extracted in step S135 are If they are the same, the process proceeds to step S138. In step S138, the angle number detection unit 182 determines the frame number N as the angle number, and supplies the angle number N to the assignment unit 183, the index image creation unit 184, and the read control unit 185. And after the process of step S138, it returns to step S113 of FIG. 21, and progresses to step S114.

  FIG. 23 is a flowchart illustrating the image size determination process in step S114 of FIG.

  In step S151, the assigning unit 183 calculates the luminance difference between the black image 231 (FIG. 19) stored as a template in the storage unit 186 and the multi-angle image supplied from the NTSC / PAL encoder 80 as a region (region). 241 and 242) are extracted and supplied to step S152.

  In step S152, the assignment unit 183 determines whether or not the difference between the areas 242 extracted in step S151 is large. If it is determined in step S152 that the difference between the areas 242 extracted in step S151 is large, the assignment unit 183 proceeds to step S153 and determines whether or not the difference between the areas 241 extracted in step S151 is small. Determine.

  If it is determined in step S153 that the difference of the region 241 extracted in step S151 is small, that is, if the region corresponding to the region 241 of the multi-angle image is black, the process proceeds to step S154. In step S154, the assigning unit 183 determines that the multi-angle image is an image having an aspect ratio of 16: 9, returns to step S114 in FIG. 21, and proceeds to step S115.

  On the other hand, if it is determined in step S153 that the difference between the areas 241 extracted in step S151 is large, that is, if the area corresponding to the area 241 of the multi-angle image is not black, the process proceeds to step S155. In step S155, the assignment unit 183 determines that the multi-angle image is an image having an aspect ratio of 4: 3, returns to step S114 in FIG. 21, and proceeds to step S115.

  If it is determined in step S152 that the difference between the areas 242 extracted in step S151 is not large, the process returns to step S151, and the angle number detection unit 182 again determines the luminance of the black image 231 and the multi-angle image. Extract the difference. That is, even when the multi-angle image is an image having an aspect ratio of 16: 9 and the multi-angle image is an image having an aspect ratio of 4: 3, all the areas corresponding to the area 242 of the multi-angle image are all. Since it is not black, the difference in luminance between the black image 231 and the multi-angle image in the region 242 is large. Therefore, when the difference in luminance between the black image 231 and the multi-angle image in the region 241 becomes small, the allocation unit 183 returns to step S151 as error processing and extracts the luminance difference again.

  FIG. 24 is a flowchart for explaining the index image creation processing in step S117 of FIG.

  In step S171, the index image creation unit 124 sets a count value B of a counter (not shown) to 1, and the process proceeds to step S172. In step S172, the index image creation unit 124 determines whether the count value B is equal to or less than the number of angles N supplied from the angle number acquisition unit 122 in step S138 of FIG.

  If it is determined in step S172 that the count value B is equal to or less than the number of angles N, the process proceeds to step S173, and the index image creation unit 184 supplies the multi-angle image data of angle #B, that is, the current image display device 11. An index signal for instructing writing of the multi-angle image data is supplied to the image display device 11.

  After the process of step S173, the process proceeds to step S174, and the index image creation unit 184 supplies a control signal to the read control unit 185 to output an angle switching command, and the process proceeds to step S175.

  In step S175, the index image creation unit 184 increments the count value B by 1, and returns to step S172.

  In step S172, when it is determined that the count value B is not less than the number of angles N, that is, greater than the number of angles N, that is, the multi-angle image data of all angles is the multi-angle image data of the angles for each angle. Is stored in the memory 142 of each image display device 11 assigned as a display target, the process proceeds to step S176, and the index image creation unit 184 reads the table from the storage unit 186. Based on the allocation information represented by the table, the index image creating unit 124 sends the multi-angle image data from the memory 142 or the multi-angle image data from the image processing unit 141 to each image display device 11 (the output selection unit 143). An index signal for instructing any one of the outputs is supplied, the process returns to step S117 in FIG. 21, and the process proceeds to step S118.

  FIG. 25 is a flowchart illustrating the read control process in step S118 of FIG.

  In step S <b> 191, the read control unit 125 determines whether or not a moving image switching command for specifying the image display device 11 for changing the assigned display form to “moving image display” is supplied from the light receiving unit 21.

  If it is determined in step S191 that the moving image switching command is not supplied from the light receiving unit 21, that is, if there is no need to change the angle of the multi-angle image data reproduced by the DVD player 164, steps S192 to S194 are skipped. Then, the process returns to step 118 in FIG.

  If it is determined in step S191 that the moving image switching command is supplied from the light receiving unit 21, that is, if it is necessary to change the angle of the multi-angle image data reproduced by the DVD player 164, the process proceeds to step S192. The read control unit 185 changes the table stored in the storage unit 186 based on the moving image switching command from the light receiving unit 21.

  After the process of step S192, the process proceeds to step S193, and the read control unit 185 determines the angle switching count S. For example, when a moving image switching command for designating the image display device 11-9 is supplied from the light receiving unit 21, the read control unit 185 reads the table from the storage unit 186, and the ID number “9” of the image display device 11-9. The angle number “3” associated with is recognized. If multi-angle image data of angle # 1 is being reproduced by the DVD player 164, the read control unit 185 sets the angle switching count S to 2 (= 3−3) as the number of angles from angles # 1 to # 3. Determine to 1).

  After the processing of step S193, the process proceeds to step S194, and the read control unit 185 outputs the angle switching command to the system controller 171 S times of angle switching determined in step S193, and returns to step S118 of FIG.

  As described above, in the disc playback apparatus of FIG. 3, the angle number acquisition unit 122 (FIG. 5) acquires the number of angles of the multi-angle image, and the allocation unit 123 determines the image display device 11 based on the angle number. For each of -1 to 11-9, one of a plurality of multi-angle image data is assigned as a display target and a display form of the display target is assigned. Then, the assigning unit 123 supplies assignment information representing the assignment result to the image display apparatuses 11-1 to 11-9, and assigns the assigned display targets to the image display apparatuses 11-1 to 11-9. Therefore, multi-angle images having a plurality of angles can be efficiently displayed on the image display devices 11-1 to 11-9.

  In the above description, the number of image display apparatuses 11 is nine, but the number of image display apparatuses 11 is not limited to this.
