Description

  The present invention relates to a video processing apparatus and method, a program, and a storage medium, and in particular, a video processing apparatus and method capable of outputting a video of the highest definition video format that can be displayed on an external device (video display device). And a program and a storage medium.

  In a video input / output device typified by a video camera, a D terminal is conventionally known as a terminal for inputting and outputting a video signal. Currently, there are five D terminals, D1 to D5 terminals, which can transmit and receive video signals of different formats of 480i, 480p, 1080i, 720p, and 1080p, respectively. Further, the D terminal is backward compatible. For example, the D5 terminal can receive all the video signals from the D1 to the D4 terminals (FIG. 3).

  In addition, a signal for determining which video format signal is flowing simultaneously with the video signal at the D terminal of the video input / output device on the video output side. Therefore, the video display device which is the video receiving side can recognize the received video format.

  In a video display device such as a television having a D terminal, it is determined whether the video format input from the D terminal is a displayable format, and if it cannot be displayed, a video mute, a blue background, or the like is displayed. .

  Such a video output side (video input / output device) does not have means for determining a video format that can be displayed on the video display device connected by the D terminal. Therefore, in order to view the video in the highest quality video format, it is necessary to check the video format supported by the video display device in advance and select the corresponding video format on the video output side.

Therefore, conventionally, a configuration has been considered in which a video format supported by the video display device is extracted on the video display device side using a spare line of the D terminal (FIG. 2) and transmitted to the video input / output device side (eg Patent Document 1). In this case, the video input / output device side and the video display device side communicate with each other using a signal that does not conform to the original D terminal standard. As a result, the video input / output device can automatically select the video image format with the highest image quality that the video display device supports.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram schematically showing a configuration of a recording / reproducing apparatus as a video processing apparatus according to an embodiment of the present invention. The recording / reproducing apparatus 100 of the present embodiment is an apparatus such as a video camera recorder.

  In FIG. 1, a recording / reproducing apparatus 100 includes a video input device 101, a video signal circuit 102, a recording / reproduction control circuit 103, a recording medium 104, an audio input device 105, and an audio signal circuit 106. The recording / reproducing apparatus 100 further includes a memory 107, a format conversion circuit 108, a liquid crystal panel 109, a D terminal 110, an operation switch 112, and a CPU 111.

  The video signal circuit 102, the recording / playback control circuit 103, the audio signal circuit 106, the memory 107, the format conversion circuit 108, and the operation switch 112 are connected to the CPU 111. The CPU 11 executes a video format selection process shown in FIGS.

  In FIG. 1, the arrow of each connection line shows the transmission direction of a signal and data. The video input device 101 includes a CCD, and the audio input device 105 includes a microphone. The recording medium 104 includes a tape, DDD, and the like.

  Signals input from the video input device 101 and the audio input device 105 are input to the video signal circuit 102 and the audio signal circuit 106, respectively, and are temporarily stored in the memory 107 as digital data according to instructions from the CPU 111. In the present embodiment, the video input device 101 and the audio input device 105 are each composed of a video camera and a microphone.

  When the input video and audio are stored in the recording medium 104, the data stored in the memory 107 is transmitted to the recording / playback control circuit 103 under the control of the CPU 111 and the data is recorded in the recording medium 104. .

  When the recorded data is reproduced, the recording / reproduction control circuit 103 reads the video and audio data from the recording medium 104, transmits them to the format conversion circuit 108, and outputs them to the liquid crystal panel 109 and the D terminal 110 in a predetermined format. In the present embodiment, the format conversion circuit 108 can output video signals in a format from 480i to 1080p corresponding to D1 terminal to D5 terminal, which will be described later.

  2A and 2B are explanatory diagrams of the D terminal in FIG. 1, in which FIG. 2A is a pin arrangement, and FIG. 2B is a correspondence table of pins and signals.

  In FIG. 2, the D terminal 110 has 14 pins, and signals are defined as shown in FIG. Pins 1 to 6 are video signals. Pins 7 to 14 define lines 1, 2, and 3, spare lines 1, 2, and 3, and plug insertion detection signals.

  Lines 1, 2, and 3 define a signal for notifying the video display device of the video format, and the video display device can determine the video format by looking at the voltages of lines 1, 2, and 3. The plug insertion detection signal is defined for detecting that the D terminal cable has been inserted into the video display device. Analog component signals flow as video signals of pins 1 to 6, and five types from D1 to D5 are defined by corresponding video formats.

  FIG. 3 is a correspondence table between the D terminal and the video format shown in FIG.

  FIG. 3 shows the correspondence between each of the D1 terminal to D5 terminal and the video format. The D1 terminal supports only 480i video format. The D2 terminal corresponds to 480p and 480i. Similarly, corresponding video formats are defined for the D3 to D5 terminals as shown in FIG.

  Thus, as the numbers from D1 to D5 terminals increase, the number of video formats that can be supported increases, and higher definition video formats are supported. Also, the D terminal having a larger number can display all video formats supported by the D terminal having a smaller number. Further, 480i can be displayed by all D terminals, and 480i can be displayed by any video display device that can be connected by the D terminal.

  FIG. 4 is a diagram schematically showing a configuration of a video display apparatus connected to the recording / reproducing apparatus of FIG.

  4, the video display apparatus 400 includes a D terminal 401, a video input circuit 402, a format conversion circuit 403, a video signal processing circuit 404, a display device 405, and a CPU 406.

  The display device 405 includes a liquid crystal, a plasma display panel, and the like, and a video format that can be displayed by the device is limited. In order to support more video formats, it is necessary to convert the input video signal into a video format that can be displayed by the display device 405.

  The signal input from the D terminal 401 is converted into data that can be processed by the video input circuit 402 and input to the format conversion circuit 403. The CPU 406 instructs the format conversion circuit 403 to convert to a format that can be displayed on the display device 405 using the video format information input from the D terminal 401. The converted video signal is processed into a signal for the display device 405 by the video signal processing circuit 404 and can be displayed on the display device 405.

  In this way, the video display apparatus 400 can display various video formats on the same display device 405, but the video that can be handled depends on the performance of the format conversion circuit 403 and the resolution of the display device 405. The format type is different, and it is determined which of the D1 to D5 terminals depends on the range that can be handled.

  FIG. 5 is a diagram showing a connection state between the recording / reproducing apparatus of FIG. 1 and the video display apparatus of FIG.

  In FIG. 5, the recording / reproducing apparatus 100 and the video display apparatus 400 are connected to D terminals (D terminals 110 and 401) of respective devices by a D terminal cable 500. When the recording / reproducing apparatus 100 outputs a video in a video format that can be displayed on the video display device 400, the video is displayed on the video display device 400. In addition, since the audio signal is not included in the D terminal, it is necessary to connect with an audio cable separately.

  FIG. 6 is a flowchart showing a procedure of video format determination processing executed by the recording / reproducing apparatus of FIG.

  This process is executed by the CPU 111 of the recording / reproducing apparatus 100. Further, as shown in FIG. 5, the D terminal 110 of the recording / reproducing apparatus 100 and the D terminal 401 of the video display apparatus 400 are connected by a D terminal cable 500, and the video display apparatus 400 displays a signal input to the D terminal 401. Ready to do.

  In FIG. 6, when the user issues a video format selection instruction to the recording / reproducing apparatus 100 using the operation switch 112, the recording / reproducing apparatus 100 starts video output processing to the D terminal 110 (step S600). A video format selection process is performed (step S601). Next, in order to perform display in a video format as high as possible, first, it is assumed that the video display device 400 is connected to the video display device 400 corresponding to D5, and a video signal is output in a 1080p video format (step S602). (Video output means). The video signal output at this time may be a video signal reproduced from the recording medium 104 as described above, or may be a specific video signal for video format selection stored in the memory 107 in advance. The CPU 111 converts the reproduced video signal or the video signal read from the memory into a 1080i format by the format conversion circuit 108 and outputs it from the D terminal 110.

  Here, the user looks at the screen of the video display device 400 and confirms whether the video is correctly displayed (step S603). If not displayed (NO in step S603), the video display device 400 does not support the video format (1080p). In that case, the user issues an instruction to proceed to the next video format to the recording / reproducing apparatus 100 with the operation switch 112. Alternatively, when there is no instruction from the user and a predetermined period has elapsed, the process returns to format selection processing step S601 in order to proceed to the next video format. In this case, the video signals in the formats from D1 to D5 are repeatedly output until a decision instruction is given while switching the video signals every predetermined period (switching means).

  Then, assuming that the video signal is connected to the video display device 400 corresponding to D4, a video signal in a 720p format is output (step S602). If 720p cannot be displayed, the process is repeated with 1080i, which is the next video format.

  FIG. 7 is a diagram for explaining the format selection order in the format selection process in the flowchart shown in FIG.

  As shown in FIG. 7, video output and confirmation processing are repeated in order from a high-definition video format from D5 (1080p) to D1 (480i).

  In FIG. 7, when the video is properly displayed on the video display device 400 (YES in step S603), the user presses the decision button or the like on the operation switch 112 to determine the video format to the recording / reproducing device 100. An instruction is given to cause the recording / reproducing apparatus 100 to fix the output to the video format (step S604) (format determining means), and this process is terminated.

  According to the process of FIG. 6, the video formats are output in the order from high definition to low definition from D5 to D1, and the video format is determined when the video is displayed on the video display device 400, so that the connection is established. Even if the user does not know the format supported by the video display device 400, the highest definition video format can be set.

  In the above embodiment, the recording / reproducing apparatus 100 first performs the selection processing step S601 of the video format to be output. Before that, the D terminal cable 500 and the audio cable (not shown) are correctly connected between the devices. It was a premise. However, since the user manually determines the video format, it is possible to easily redo even if the connection between devices is incorrect.

  The above embodiment is an example in which the user manually determines the video format, but the recording / reproducing apparatus 100 may automatically determine the video format.

  FIG. 8 is a flowchart showing the procedure of a modification of the video format determination process of FIG.

  This process is executed by the CPU 111 of the recording / reproducing apparatus 100.

  In FIG. 8, first, the recording / reproducing apparatus 100 outputs the video format of 480i to the D terminal 110 (step S801), and simultaneously the recording / reproducing apparatus 100 also outputs test audio in order to confirm the connection between devices in advance (step S801). Step S802). The test audio signal is stored in the memory 107, and the CPU 111 reads the test audio signal from the memory 107 and outputs it. Since the video format of 408i can be displayed on all the video display devices 400 having the D terminal 401, it is displayed on the video display device 400 if the connection is correct.

  If the connection is correct, the video display device 400 displays the 480i video format. In this case, the video input device 101 of the recording / playback apparatus 100 is directed to the video display apparatus 400, and the video displayed on the video display apparatus 400 is input from the video input device 101 to the recording / playback apparatus 100. Then, it is determined whether or not the video displayed on the video display device 400 is correctly output based on the input video data (step S803).

  As a video signal at that time, a simple test pattern such as a color bar that can be easily discriminated by the video input device 101 is used. Further, means for determining whether or not the video displayed on the video display device 400 is correct can be used by using existing technology. For example, there is a technique in which a correlation between an output video and a video input by the video input device 101 is obtained and a determination is made based on the matching degree of the video.

  Since the purpose is to check whether the video is displayed on the video display device 400, it may be included in a part of the video input by the video input device 101, and the size of the video matches. There is no need.

  Similarly to the video signal, the test audio is output for the audio, and it is determined whether the audio is correctly output from the video display device 400 based on the signal received by the audio input device 105.

  At this time, the output of the video signal is stopped while the test audio is output, and when the video is not input on the video display device 400, it is automatically confirmed that the audio is muted. If the audio is not muted when the output of the video signal is stopped, the audio is not used in the subsequent processing.

  As a result of the determination in step S803, when the video and audio are correctly output by the video display device 400, the video format selection process (step S804) is equivalent to D5 in order to display the video format as high as possible. Is output from a 1080p video format (step S805) (video output means).

  If the result of determination in step S803 is that video and audio are not output correctly, this is notified to the user by displaying on the liquid crystal panel 109, and the connection is confirmed, and the video input device 101 is directed to the video display device 400. Give instructions to do so.

  Next, the recording / reproducing apparatus 100 determines whether the video is correctly displayed on the video display apparatus 400 from the video input of the video input device 101, and whether the audio is also correctly output using the audio input device 105. A determination is made (step S806). If the video and audio are not correctly displayed on the video display device 400 (NO in step S806), the video display device 400 does not support the video format, so the recording / playback device 100 performs processing to the next video format. Proceed.

  As a result of the determination in step S806, if video and audio are not displayed, the processing after step S804 is repeated, and as a format selection process, it is next connected to the video display device 400 corresponding to D4. Assume that video output is performed in a 720p video format (step S805). The same processing is repeated until the video display is confirmed while switching the video format (switching means).

  As a result of the determination in step S806, when the video and audio on the video display device 400 are correctly displayed on the recording / playback apparatus 100, the user presses the enter button or the like (instruction means) to the video recording format on the recording / playback apparatus 100. After making the determination, the output of the recording / playback apparatus 100 is fixed to the video format (step S807) (format determining means), and this process ends.

In the present modification, the recording / reproducing apparatus 100 automatically tries to determine whether or not an image is displayed on the image display apparatus 400. Therefore, if the connection is not correct, normal processing cannot be performed. Therefore, in order to determine whether the video and audio output from the D terminal and the audio output terminal are correctly output by the video display device 400, it is necessary to confirm connection in advance.
In this modification, this connection confirmation is automatically performed in advance using the video input device 101 and the audio input device 105, and then the optimal video format is automatically selected by performing the same processing as in FIG. To do.

  According to the process of FIG. 8, the recording / playback apparatus 100 can automatically set the highest definition video format that can be displayed by the video display apparatus 400. Therefore, the user can easily view the video in the optimum video format without knowing the video format that the video display device 400 can display.

  In the above embodiment, when the video format output from the recording / reproducing apparatus 100 is a video format not supported by the video display apparatus 400 connected by the D terminal (D terminals 110 and 401), the video display apparatus 400 is displayed. Then nothing is displayed. For this reason, the user cannot know what video format the recording / reproducing apparatus 100 is outputting. In addition, the user cannot confirm whether the video format is changed in order until the display is performed on the video display device 400.

  Accordingly, it is necessary to inform the user of the video format output by the recording / reproducing apparatus 100 by some method. However, when the recording / reproducing apparatus 100 has a liquid crystal monitor, the video format output together with the output video is displayed. The type can be displayed.

  FIG. 9 is a diagram showing a display screen of a liquid crystal monitor attached to the image reproducing apparatus shown in FIG.

  As shown in FIG. 9, the type of video format output together with the video currently output to the D terminal 110 is displayed on the liquid crystal monitor 900 of the recording / reproducing apparatus 100 (video display means). By displaying the type of video format, the user can be notified of the video format output by the recording / reproducing apparatus 100.

  When the user forgets to connect the D terminal cable 500 or when the video display device 400 is not set to display the signal of the D terminal 401, nothing is displayed on the video display device 401. Followed.

  However, if the type of video format being output is displayed together with the video currently being output on the liquid crystal monitor 900, the user can grasp the connection state between the recording / reproducing apparatus 100 and the video display apparatus 400.

  For example, the video format of 480i is always displayed on the video display device 400 having the D terminal 401. Therefore, when this is not displayed, it is possible that the D terminal cable 500 is not correctly connected or the video display device 400 is set to display the signal of the D terminal. In this case, a message to that effect can be displayed on the display screen of the liquid crystal monitor 900 to prompt the user to confirm the connection.

  Although the video output to the D terminal has been described in the above embodiment, the present invention is not limited to the D terminal. The recording / reproducing apparatus 100 is characterized in that it selects the highest definition video format that the video display apparatus 400 can display while sequentially outputting video data of a plurality of video formats to the video display apparatus 400.

  Another object of the present invention is to supply a storage medium (or recording medium) on which a program code of software that realizes the functions of the above-described embodiments is recorded to a system or apparatus, and to provide a computer (or CPU or CPU) of the system or apparatus. Needless to say, this can also be achieved by reading the program code stored in the storage medium.

  As a storage medium for supplying the program, for example, RAM, NV-RAM, floppy (registered trademark) disk, optical disk, magneto-optical disk, CD-ROM, MO, CD-R, CD-RW, DVD (DVD-ROM, DVD-RAM, DVD-RW, DVD + RW), magnetic tape, non-volatile memory card, and other ROMs may be used as long as they can store the program. Alternatively, the program is supplied by being downloaded from another computer or database (not shown) connected to the Internet, a commercial network, a local area network, or the like.

  In this case, the program code itself read from the storage medium realizes the functions of the above-described embodiment, and the storage medium storing the program code constitutes the present invention.
