Description

  The present invention relates to an apparatus for processing data, particularly video data.

  In a live house or the like, video entertainment is performed in which a video jockey (VJ) changes a video displayed on a large screen in accordance with music on the stage. In this way, the audience enjoys watching and changing images from screen to screen. Specifically, the VJ performs a real-time operation of applying various effect processes to the video or switching a plurality of videos using various methods. At this time, a video mixer is used as a device for finally generating a video by inputting a plurality of video materials and applying effect processing to each video and then synthesizing each video.

  In such video editing work, after understanding the contents of a large number of effect processing and complicated mixing methods, a technique for operating a device quickly in accordance with music is required. It takes a considerable amount of time to acquire such a technique, and it has been difficult for general users to easily express such images.

  Thus, for the purpose of easily handling complicated video processing, a series of processing contents are registered in advance (see, for example, Patent Documents 1 and 2). Hereinafter, such a processing procedure is referred to as “macro”.

  However, for users who are not proficient in video editing technology, creating a macro is a cumbersome task, and even if a macro is created, it is accurate to determine what kind of processing the macro defines. If you don't know it, you can't use it. For example, it can be confirmed that the content of the macro is a processing content such as “wiping is performed from left to right for 3 seconds while applying mosaic to the input video 1 and the screen is changed to the input video 2”. This is because it is difficult for a user unfamiliar with video editing work to imagine what kind of video is actually generated by the user even though it can be understood in theory.

<Example>
FIG. 1 is a diagram showing a functional configuration of a video editing apparatus 1 according to the present invention. As shown in the figure, the video editing apparatus 1 includes a control unit 11, a video input unit 12, a mixer unit 13, a video output unit 14, an operation unit 15, a macro switching / display unit 16, and a bus 17. The control unit 11 includes a CPU, a RAM, a ROM, and the like, and controls each unit. The video input unit 12 has a plurality of video input terminals, and a plurality of video signals are input via the input terminals and output to the mixer unit 13.

  The mixer unit 13 is composed of an image processing processor or the like, processes the input video according to a processing method specified by the user, and supplies the processed video to the video output unit 14. Here, the video processing method refers to the type and content of video effect processing, or a series of video effect processing procedures (hereinafter referred to as macro). The effect processing refers to unit image processing such as color correction, overlap, wipe, master fade, and PinP (picture-in-picture). The macro defines the unit effect processing procedure described above. For example, the video 1 and video 2 are first wiped from right to left for 5 seconds from the state in which the input video 1 is being played back. Then, the content of the process is such that the screen is switched to the input video 2 and then the dissolve process is performed for 10 seconds to switch the screen to the video 1.

  In the following, for convenience of explanation, the macro content is “video input 1 = color change (level 5), mosaic (level 3); input video 2 = color change (level 2), mosaic (level 6); mixing = wipe (3 Second, left to right) ”. The meaning of this notation is “the input video 1 is subjected to level 5 color change processing and level 3 mosaic processing, and the input video 2 is subjected to level 2 color change processing and level 6 mosaic. After performing the process, the wipe process is performed from left to right for 3 seconds as a mixing process for both images. "

  FIG. 2 is a diagram illustrating a detailed configuration of the mixer unit 13. As shown in the figure, the mixer section 13 includes effect processing units of a color change processing section 131a, a mosaic processing section 131b,. Each of these video processing units can perform processing for each input video. The video processed by each video processing unit is input to the mixing processing unit 132, and mixing processing is performed. In FIG. 2, only two effect units are shown, but this is only an example, and it goes without saying that the number of effect units can be appropriately prepared according to the type of effect required. Absent.

  For example, the video processing method designated by the user is “video input 1 = color change (level 5), mosaic (level 3); input video 2 = color change (level 2), mosaic (level 6); mixing = wipe, If the macro is “3 seconds, left to right”, the color change processing unit 131a performs level 5 and level 2 color change processing on the input videos 1 and 2, respectively. Similarly, the mosaic processing unit 131b performs level 3 and level 6 mosaic processing, respectively. Then, the mixing processing unit 132 outputs a video signal obtained by performing a wiping process on the input videos 1 and 2 processed in this way. As described above, the mixer unit 13 continues to process the sequentially input images in real time according to the same image processing method until the user newly designates the image processing method.

  The video output unit 14 includes a video output terminal for connection to an external display device, and outputs the video processed by the mixer unit 13 to an external display device such as a CRT or a liquid crystal display. Thereby, the user can visually recognize the processed video.

  As shown in FIG. 3, the operation unit 15 has operation elements such as buttons and dials, and the user can specify a processing method and register a macro by operating the operation elements. It has become. In the figure, the block of “input video 1” is for designating an effect to be given to the input video 1. When specifying the processing method, turn the dial to set the effect level, and press the button for specifying the effect type, such as “color change” or “mosaic”. Then, the mixer unit 13 starts the effect processing of the set type and level for the input video 1. The same applies to the “input video 2” block.

  The “mixing” block designates a mixing method for a plurality of input videos (two in the figure). When a desired parameter is set by turning the dial and a button such as “wipe” or “PinP” is pressed, the input video 1 and 2 (if effect processing is specified for each input video, the effect processing is performed) in the mixer unit 13. The mixing process for the subsequent videos 1 and 2) is started.

  The “macro” block is used for macro registration and macro content editing. First, the user presses the buttons F1 to F5 for registering the macro while pressing the “Register” button. Subsequently, as described above, a predetermined operation is performed on the input images 1 and 2 and the mixing block, a desired series of processing procedures are input, and finally the “registration” button is pressed to register. Is completed.

  As a result, for example, the button “F1” has “video input 1 = color change (level 5), mosaic (level 3); input video 2 = color change (level 2), mosaic (level 6); mixing = wipe ( 3 ”, left to right)” is registered, and “video input 1 = mosaic (level 4); input video 2 = mosaic (level 1); mixing = PinP (10 seconds, A macro M2 having a content of “video 1)” is registered at the center of video 2. The contents of the macro registered in this way are output to the control unit 11 and written to the ROM in the control unit 11.

  The macro switching / display unit 16 includes buttons F1 to F5 and display units D1 to D5 such as a liquid crystal display below the buttons F1 to F5. The buttons F1 to F5 are associated with macros M1 to M5 registered by the user. Specifically, when the user wishes to perform processing using the macro M1, the user presses the F1 button. Then, information that the macro M1 has been selected is sent to the mixer unit 13 via the control unit 11. As a result, the mixer unit 13 follows the macro M1 for the input video under the control of the control unit 11. The processing is started.

  Each display part D1-D5 displays the sample image | video corresponding to each macro. That is, the control unit 11 reads a sample video from, for example, a ROM, processes the video according to each macro M1 to M5, and displays the processed video. As a result, for example, an image that has been subjected to the macro M1 wipe process is repeatedly displayed every three seconds on the display unit D1. In this way, since the registered macro processing state is displayed as a sample image on the display units D1 to D5, the user can see what the content of the macro M1 registered by the user is as a video. Can be understood intuitively. The user designates a desired macro while referring to the video, and presses a corresponding button to start a desired video processing process in the mixer unit 13.

  In addition, when it is desired to cancel the designation of the effect process and the mixing process, it can be performed by pressing the corresponding button (the pressed button) again. Each macro button may be alternatively selectable, or a plurality of macro buttons may be simultaneously specified. When the macro button and other buttons are pressed at the same time, the macro processing may be applied with priority. In addition, in order to notify the button pressed state in an easy-to-understand manner, the button may emit light when pressed.

<Modification>
The present invention is not limited to the above-described embodiment, and for example, the following modifications are possible.

  The number of macros that can be registered is arbitrary. If the number of display units is smaller than the number of registered macros and all the macros cannot be displayed, only some of the macros may be displayed. For macro registration, two buttons, a “registration start” button and a “registration completion” button, may be prepared. In this case, it is not necessary to operate other buttons while pressing the “Register” button. Specifically, first, the “registration start” button is pressed, the effect setting operation is performed, and then the “registration complete” button is pressed to complete the registration. Furthermore, the user may input setting parameters related to all effect processing and mixing processing using an operator or the like. However, when registering a macro, the timing at which the setting operation is performed is recorded and the timing is recorded. As described above, a series of processing processes may be executed. For example, when the content of the macro is “Mosaic processing is performed for 1.5 seconds and then Dissolving processing is performed for 2 seconds”, values of “1.5 seconds” and “2 seconds” are used as parameters of the respective processing. For example, after the button for registering the mosaic process is continuously pressed for 1.5 seconds, the button for registering the dissolve process is continuously pressed for 2 seconds. The video editing apparatus 1 records button press timing information from the operation unit 15 and generates time parameters (“1.5 seconds” and “2 seconds” in this example) from this information. In other words, a series of processing procedures are input in real time. In this way, it is possible not only to save time for inputting parameters related to time such as effect time, but also to register subtle user feelings that are difficult to express by numerical designation as macros.

  A plurality of macros may be grouped and a macro switching button may be assigned to each group. Specifically, when registering a macro, the attribute of the macro is also registered. Attributes are the characteristics, properties, and impressions that effect processing has on viewers in common with each effect process. For example, "flashy", "stringent", "nagomi", and "speed" Conceivable. The effects having the same attribute are set to the same group. For example, effects having six “flashy” attributes of macros M11 to M16 are assigned to the button F1. In this case, by default, an image representing the macro M11 is displayed on the display unit D1, and when the button is further pressed in this state, an image representing the macro M12, an image representing the macro M13, and so on are sequentially switched. You may do it. By adopting such a display method, it is possible to easily find a desired macro from a large number of macros. Further, instead of determining the attribute (that is, the group) by the user, the control unit 11 may determine the macro contents and automatically perform grouping.

  Further, as described above, as the image processing method, different parameters (effect applying time, effect level, etc.) can be set for a plurality of input images. Therefore, for example, when a plurality of effect processes having different effect times are executed simultaneously, each effect process ends in a timely manner, and the resulting video may be unsightly. In this case, for example, the control unit 11 may correct the parameter so that the time of all the other effect processes is matched with the effect with the shortest (or longest) time. Alternatively, the priority order may be determined for each effect in advance, and the processing time of all effects may be corrected to match the effect processing time of the effect with the highest priority.

  In the above-described embodiment, the video displayed on the display units D1 to D5 is sample video data irrelevant to the input video. However, the present invention is not limited to this. For example, the video data of the input video 1 is the size of the display unit. It is also possible to use video data that has been reduced in accordance with the above. Specifically, when processing is currently proceeding according to the macro M1, the mixer unit 13 reduces the data of the input video 1 in accordance with the sizes of the display units D1 to D5 separately from the macro M1. The video processing is executed according to the macros M1 to M5, and these are displayed on the display units D1 to D5, respectively.

  As a result, the user can check the outline of the video generated and output to the external display device when the macro processing M1 to M5 is performed on the video input in real time. That is, the user does not need to actually perform a macro switching operation and output it to the external display device for confirmation. With reference to the video displayed on the display units D1 to D5, the most suitable macro for the current input video can be instantly selected and switched. Providing such a user interface can be a guideline for selecting a desired processing process for users who are not familiar with video editing, and is also expected to stimulate creativity for video editing experts. Is done.

  In the above-described embodiments, the functions of the present invention are realized by the video editing device as a hardware device. However, the present invention is not limited to this, and the functional configuration of the present invention is implemented as software that can be executed by a personal computer (PC) or the like. May be. In this case, effect processing and macro setting / switching are performed by an input device such as a keyboard or a mouse instead of the operation unit 15. Further, on the display screen of the PC, the processed video is displayed in the display window 201. For example, an operation window 202 and a window 203 for displaying a video representing the macro contents are displayed at the same time. It is good. An example of this display screen configuration is shown in FIG.

  In the embodiment described above, the processing target is a video signal, but only the audio signal or a signal in which the video signal and the audio signal are mixed may be the processing target. In the case of audio-only processing, the image to be displayed on the display units D1 to D5 is arbitrary, and in short, it may be a still image or a moving image that allows the user to identify each macro content.

  In the above-described embodiment, it is assumed that the input video is processed in real time. However, the present invention is not limited to this, and video data is once captured in a storage device such as a hard disk of a PC, and then video The present invention is also applicable to a so-called non-linear editing mode in which video data is output to the editing apparatus 1 and the processed video is stored in a hard disk.

  In the above-described embodiment, the video displayed on the display units D1 to D5 is the video representing the macro content, but it goes without saying that it may be the content of a single effect process or mixing process. For example, “wipe” is assigned to the button “F1”, “PinP” is assigned to the button “F2”, and a sample image of the wipe process and a sample image of PinP are displayed on the D1 and D2, respectively. This makes it possible to intuitively understand basic effect processing even if the video editing is a complete beginner, and to enjoy editing easily.
