Description

  The present invention relates to a video special effect device that applies a special effect to a video and a control method thereof, and more particularly to a video special effect device that applies a special effect to video of two types of formats and a control method thereof.

  In recent years, in the field of television broadcasting, high-definition HD (High Definition) format program production and broadcasting have been performed, and at the same time, conventional SD (Standard Definition) format broadcasting has been maintained. For this reason, the same content video is broadcast simultaneously in two types of HD format and SD format.

  On the other hand, during program production and broadcasting, a video special effect device called an effect switcher is used to superimpose subtitles on the video by keying, or another sub-screen is placed on a part of the screen (picture-in Picture) is widely done.

  Conventionally, the following method (1) or (2) has been used as a method of generating video of two types of formats with such special effects.

  (1) As shown in FIG. 1, one special effect circuit 102 is controlled from the operation panel 101. The special effect circuit 102 receives a video signal in the original format (either one of the HD format and the SD format). The operator designates the position on the operation panel 101 where the subtitle is superimposed or the child screen is arranged by using the coordinates on the screen while confirming the input video to the special effect circuit 102 on a monitor (not shown). Based on this operation, the video effected with the special effect by the special effect circuit 102 is output as it is, and the format converter 103 converts it into the other format and outputs it.

  (2) As shown in FIG. 2, two special effect circuits 112 and 113 are simultaneously controlled from the operation panel 111. The video signal of the original format (either one of the HD format and the SD format) is input to the special effect circuit 112 as it is, and at the same time, converted into the other format by the format converter 114 and the special effect circuit 113. To input. The operator confirms the input video to one of the special effect circuits 112 and 113 on a monitor (not shown), and uses the operation panel 111 to set the position where the subtitle is superimposed or the sub screen is arranged on the screen. Specify with the coordinates above. Based on this operation, the special effect circuits 112 and 113 output the video with special effects by keying as they are.

  By the way, in order to broadcast high-value-added video in television broadcasting, it is desired to superimpose captions or arrange a sub-screen at an optimal position according to the respective formats such as HD format and SD format. However, in the methods (1) and (2), it is difficult to apply a special effect to the position on the screen according to each format due to the difference in aspect ratio between the HD format and the SD format. This will be described with reference to FIGS.

  FIG. 4 is a diagram illustrating a state in which subtitles are superimposed on video in HD format and SD format by the methods (1) and (2).

  FIGS. 4A and 4B show HD format and SD format videos having the same contents, respectively. The aspect ratio of the HD format video is 16: 9, and the aspect ratio of the SD format video is 4: 3.

  4 (c) and 4 (d) show a state in which captions are superimposed by the method (1) shown in FIG. Of these, FIG. 4C shows the HD format video of FIG. 4A being input to the special effect circuit 102, and the HD panel video is confirmed on the monitor while the operation panel 101 displays FIG. 16: 9 coordinates on the screen (the distance from the screen center to the edge of the screen is taken as 100%, and the distance from the screen center is relatively expressed (and therefore the distance from the screen edge is relatively (Representation) value) is specified as 67%, and a special effect circuit 102 superimposes a 33% vertical subtitle (video commentary). Subtitles are superimposed at the bottom of the screen.

  On the other hand, FIG. 4D shows a state in which the video in FIG. 4C is converted to the SD format by the format converter 103 (converted to the letterbox format, which is a format in which blank portions are added above and below the video portion). Show. Due to the addition of margins above and below the video part, the position of the subtitle has shifted to the upper side. Therefore, subtitles cannot be superimposed at the optimum position in the SD format video (here, the lower end of the screen as in the HD format video).

  FIGS. 4E and 4F show a state in which captions are superimposed by the method (2) shown in FIG. Of these, FIG. 4E shows that the HD format video of FIG. 4A is directly input to the special effect circuit 112, and the HD panel video is confirmed on the monitor by the operation panel 111 while FIG. In this way, the 16: 9 screen coordinate is specified as 67%, and the special effect circuit 112 superimposes a 33% vertical subtitle (video commentary). Subtitles are superimposed at the bottom of the screen.

  On the other hand, in FIG. 4F, the special effect circuit 113 converts the HD format video in FIG. 4A into the SD format as shown in FIG. And the special effect circuit 113 superimposes the subtitles. Since the coordinate is designated as 67% on the operation panel 111, the subtitle is superimposed at the position of the coordinate 67% as shown in FIG. 3B on the 4: 3 screen in the SD format. However, since the vertical portions of the subtitles are smaller than 33% due to the addition of blank portions above and below the video portion, the subtitle position is shifted to the upper side. Therefore, subtitles cannot be superimposed at the optimum position in the SD format video (here, the lower end of the screen as in the HD format video).

  FIG. 5 is a diagram exemplifying a state in which a sub-screen is arranged on a video in HD format and SD format by the methods (1) and (2).

  FIGS. 5A and 5B show HD format and SD format videos having the same contents, respectively.

  FIGS. 5C and 5D show a state in which captions are superimposed by the method (1) shown in FIG. Of these, FIG. 5 (c) shows the 16: 9 screen on the operation panel 101 while inputting the HD format video of FIG. 5 (a) to the special effect circuit 102 and confirming the HD format video on the monitor. A state in which the sub-screen (screen of the person's video) is arranged by the special effect circuit 102 by specifying the coordinates at is shown. A sub-screen is placed near the top of the screen.

  FIG. 5D shows a state where the video in FIG. 5C has been converted to the SD format (converted in the letterbox format) by the format converter 103. Due to the addition of margins above and below the video part, the position of the sub-screen has moved downward. Therefore, the child screen cannot be arranged at the optimum position in the SD format video (here, the vicinity of the upper end of the screen as in the HD format video).

  FIGS. 5E and 5F show a state in which captions are superimposed by the method (2) shown in FIG. Of these, FIG. 5E shows the 16: 9 screen displayed on the operation panel 111 while the HD format video in FIG. 5A is directly input to the special effect circuit 112 and the HD format video is confirmed on the monitor. The state where the above-mentioned coordinates are designated and the sub-screen (screen of the person's video) is arranged by the special effect circuit 112 is shown. A sub-screen is placed near the top of the screen.

  In FIG. 5F, the HD format video in FIG. 5A is converted into the SD format as shown in FIG. 5B by the format converter 114 (converted in the letterbox format) and input to the special effect circuit 113. FIG. 5 shows a state in which a sub-screen (screen of a person's video) is arranged by the special effect circuit 113. Even on the 4: 3 screen in the SD format, the child screen is arranged at the same coordinate position as specified on the operation panel 111. However, since the vertical width of the child screen is reduced by adding blank portions above and below the video portion, the position of the child screen is shifted to the lower side. Therefore, the child screen cannot be arranged at the optimum position in the SD format video (here, the vicinity of the upper end of the screen as in the HD format video).

  As described above, in the conventional method for generating video of two types of formats with special effects, the position on the screen according to each format is different from the difference in aspect ratio between the HD format video and the SD format video. It was difficult to apply special effects to

  Here, in the method (2) shown in FIG. 2, while confirming both the HD format video and the SD format video on the monitor simultaneously on the monitor, the operation panel 111 displays the 16: 9 screen. If the coordinates and the coordinates on the 4: 3 screen are specified separately in parallel, a special effect can be applied to the optimum position on the screen according to each format. However, it is troublesome to check two images on the monitor simultaneously in parallel. Further, the present applicant has proposed an invention (see Patent Document 1) for designating the position of a picture-in-picture on the screen by a simple operation. It is still complicated to separately specify the coordinates on the screen 9 and the coordinates on the 4: 3 screen simultaneously in parallel.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 6 is a diagram showing an example of the overall configuration of an effect switcher to which the present invention is applied. In this effect switcher, a main unit 1 and an operation panel 2 are connected by a communication path 3 such as a LAN (local area network).

  The main unit 1 has input lines 4 (1) to 4 (9) for inputting video signals from video cameras, VTRs, etc., and two sets of mix / effect banks (hereinafter simply referred to as banks) 5 and 6, respectively. Also, format converters 7 and 8 and a microcomputer 17 for controlling each part in the main unit 1 are provided.

  The video input to the effect switcher includes both an HD format video with an aspect ratio of 16: 9 and an SD format video with an aspect ratio of 4: 3. The input lines 4 (1) to 4 (9 Which format video is to be input to each is previously set at the time of setting up the effect switcher.

  The video of the input lines 4 (1) to 4 (9) is sent to the bank 5 via the format converter 7. The format converter 7 converts the SD format video to the HD format having an aspect ratio of 16: 9 from the video of the input lines 4 (1) to 4 (9), and outputs the HD format video. It outputs as it is without. Accordingly, since only HD format video with an aspect ratio of 16: 9 is output from the format converter 7, only HD format video with an aspect ratio of 16: 9 is sent to the bank 5.

  The bank 5 is provided with a key video selection switch 9, a background video selection switch 10, and a special effect circuit 11. The background video selection switch 10 is a switch for selecting a background video from the video on the input lines 4 (1) to 4 (9). The key video selection switch 9 is a switch for selecting a video to be used for keying from the video on the input lines 4 (1) to 4 (9). And a switch 9b for selecting a key source signal (an area for overlaying the key fill signal, a shape for cutting out the background video, and a video for designating the density of the key fill signal with respect to the background video). ing.

  The special effect circuit 11 performs special effects such as subtitle superposition and picture-in-picture on the background video selected by the background video selection switch 10 by keying using the video selected by the background video selection switch 9. It is a circuit to be applied. The HD format video signal to which the special effect is applied by the special effect circuit 11 is output from the output line 15 to the outside of the main unit 1.

  The video of the input lines 4 (1) to 4 (9) is sent to the bank 6 through both the format converter 7 and the format converter 8. As described above, only HD format video with an aspect ratio of 16: 9 is output from the format converter 7, but the format converter 8 converts all video from the format converter 7 to SD format with an aspect ratio of 4: 3. And output. Accordingly, only the SD format video having an aspect ratio of 4: 3 is sent to the bank 6. As another example, the video supplied from the outside to the input lines 4 (1) to 4 (9) is sent to the bank 6 via the format converter 8 only, and only the HD format video is sent to the format converter. Even if the image is converted to the SD format at 8, only the SD format video having an aspect ratio of 4: 3 can be sent to the bank 6.

  The configuration of the bank 5 is the same as that of the bank 6, and a key video selection switch 12, a background video selection switch 13, and a special effect circuit 14 are provided. The SD format video signal subjected to the special effect by the special effect circuit 14 is output from the output line 16 to the outside of the main unit 1.

  The operation panel 2 includes a button arrangement unit 21 and a parameter input operation unit 22 on the panel surface, and a microcomputer 23.

  The button arrangement unit 21 includes a key selection operation unit 21 a for controlling the key video selection switches 9 and 12 of the banks 5 and 6 of the main unit 1 and a background video selection switch of the banks 5 and 6 of the main unit 1. A background selection operation unit 21b for controlling 10 and 13 is arranged.

  The parameter input operation unit 22 is an operation unit for inputting various parameters for controlling the special effect circuits 11 and 14 of the banks 5 and 6 of the main unit 1 through a GUI (graphical user interface), a rotary dial, or the like. It is. The parameters input by the parameter input operation unit 22 specify parameters related to the position where the special effect is applied on the background video screen (the position where subtitles are superimposed or sub-screens are placed), and the subtitle or sub-screen reduction ratio is specified. There are parameters to do.

  As a feature of the present invention, in the parameter input operation unit 22, the parameters relating to the position where the special effect is applied on the screen of the background video are not the coordinates as shown in FIGS. 3A and 3B but the four corners of the screen. (Upper left corner, upper right corner, lower left corner, lower right corner) or parameters that specify one of the edges (upper edge, lower edge, left edge, right edge), or parameters that have been set in advance for the purpose of screen configuration depending on the operator's sensitivity It comes to input.

  In addition, the parameters input by the parameter input operation unit 22 include items common to the HD format and the SD format, and items not common to the HD format and the SD format. Whether or not is input can be determined by the type of parameter. The parameter relating to the position where the special effect is applied is an item not common to the HD format and the SD format.

  In response to the operation of the button placement unit 21 or the parameter input operation unit 22, the microcomputer 23 controls the button placement unit 21 or the parameter input operation unit 22 (for example, turns on the LED built in the operated push button). And a signal indicating the operation content is sent from the operation panel 2 to the microcomputer 17 of the main unit 1 via the communication path 3.

  The microcomputer 17 of the main unit 1 controls each part in the main unit 1 based on a signal from the microcomputer 23 of the operation panel 2. As a feature of the present invention, the internal memory 18 has a first position. An area of the adjustment value storage unit 19 and an area of the second position adjustment value storage unit 20 are provided.

  In these position adjustment value storage units 19 and 20, among the parameters input by the parameter input operation unit 22, the HD format and the SD format format corresponding to the parameters of items not common to the SD format are stored. An adjustment value of 1 and a second adjustment value for SD format are stored.

  FIG. 7 is a diagram illustrating a part of the contents stored in the position adjustment value storage units 19 and 20 corresponding to the same parameter. Parameters 1 to 4 are parameters of items that are not common to the HD format and the SD format, respectively, and the first adjustment value and the second adjustment value are respectively position-adjusted corresponding to the parameters 1 to 4. The values are stored in the value storage unit 19 and the position adjustment value storage unit 20.

  Of these, parameter 1 is a parameter for designating the lower end of the screen as the position to apply the special effect. The first adjustment value 67 corresponding to the parameter 1 is a screen when a 33% vertical subtitle is superimposed on a lower corner of a 16: 9 screen of HD format video or a sub screen with a vertical width of 33% is arranged. It is the distance (coordinates shown in FIG. 3A) from the center to the bottom edge of the screen.

  The second adjustment value 75 corresponding to this parameter 1 is the same as the same subtitle superimposed on the lower corner of the 4: 3 screen of the video obtained by converting the HD format video to the SD format (converted in the letterbox format). This is the distance (coordinates shown in FIG. 3B) from the screen center to the bottom edge of the screen when a child screen is arranged. In the case of a 4: 3 screen in letterbox format, a subtitle or sub-screen having a vertical width of 33% on a 16: 9 screen has a vertical width of 33 × {( 4/3) / (16/9)} ≈25%. Therefore, the second adjustment value is set to 75 corresponding to the vertical width of 25%.

  Although omitted in FIG. 7, the position adjustment value storage units 19 and 20 store subtitles and sub-screens having a vertical width other than 33% on the 16: 9 screen corresponding to the parameter 1. The first adjustment value and the second adjustment value are also stored. Similarly, for the parameters that specify one of the four corners of the screen, the top edge, the left edge, or the right edge, a plurality of first adjustments are made according to the size of the subtitles and sub-screens (vertical width and horizontal width). A value and a second adjustment value are stored corresponding to each other.

  Parameters 2 to 4 are parameters set in advance for the purpose of screen configuration based on the sensitivity of the operator. The first adjustment value and the second adjustment value corresponding to these parameters 2 to 4 are values set by the operator as appropriate values on the 16: 9 screen and the 4: 3 screen, respectively.

  FIG. 8 shows processing executed by the microcomputer 17 when the parameter input operation unit 22 is operated (when a signal indicating the operation content of the parameter input operation unit 22 is sent from the microcomputer 23 of the operation panel 2). It is a flowchart. In this process, first, information indicating the parameter type K input by the parameter input operation unit 22 is acquired (step S1).

  Subsequently, it is determined whether or not the type K parameter is an item common to the HD format and the SD format (step S2). If no, the first adjustment value p1 corresponding to the type K parameter is read from the position adjustment value storage unit 19 (step S3). As described above, a plurality of first adjustment values correspond to the parameters for specifying one of the four corners or the edge of the screen according to the size (vertical width or horizontal width) of the subtitle or the sub-screen. In this case, in step S3, the size of the subtitle selected in the key selection operation unit 21a of the button arrangement unit 21 of the operation panel 2 or the size of the sub-screen (the subtitles and subtitles in the parameter input operation unit 22) are stored. When a parameter for reducing the screen is input, the first adjustment value p1 corresponding to the size multiplied by the reduction ratio is read. For example, if the type K is a parameter for designating the lower corner of the screen and the size of the subtitle or sub-screen on the 16: 9 screen is 33%, the first adjustment value 67 in FIG. 7 is read as p1.

  Then, the special effect circuit 11 is arranged so as to superimpose subtitles or arrange a sub-screen at a position based on the adjustment value p1 (for example, if the adjustment value p1 is 67 in FIG. 7, the lower end of the 16: 9 screen). Control (step S4).

  Subsequently, the second adjustment value p2 corresponding to the type K parameter is read from the position adjustment value storage unit 20 (step S5). Even in step S5, in the case of a parameter that designates one of the four corners or edges of the screen, the size of the subtitle or subscreen selected by the key selection operation unit 21a (the subtitle or subscreen is selected by the parameter input operation unit 22). When a parameter to be reduced is input, the second adjustment value p2 corresponding to the size multiplied by the reduction ratio is read out. For example, if the type K is a parameter for designating the lower corner of the screen and the size of the subtitle or sub-screen on the 16: 9 screen is 33%, the second adjustment value 75 in FIG. 7 is read as p2.

  Then, the special effect circuit 14 is arranged so as to superimpose the subtitle or arrange the sub-screen on the position based on the adjustment value p2 (for example, if the adjustment value p2 is 75 in FIG. 7, the lower end of the 4: 3 screen). Control (step S6). Then, the process ends.

  If yes in step S2, the special effect circuits 11 and 14 are controlled by the type K parameter (steps S7 and S8), and the process is terminated.

  Next, in this effect switcher, the background video selection switch 10 in the bank 5 and the background video selection switch 13 in the bank 6 select the same input line, and the key video selection switch 9 in the bank 5 and the key video selection in the bank 6 are selected. A state in which a video of the same input line is selected by the switch 12 and a special effect is simultaneously applied by the special effect circuit 11 and the special effect circuit 14 will be described.

  FIG. 9 shows the same background video as shown in FIGS. 4A and 4B, with the same subtitles as shown in FIGS. 4C and 4D, and FIGS. 4E and 4F. It is a figure which shows a mode that a description sentence of an image | video is superimposed.

  FIGS. 9A and 9B show an HD format background video and an SD format background video (HD format) sent from the background video selection switch 10 and the background video selection switch 13 to the special effect circuit 11 and the special effect circuit 14, respectively. Is converted to the SD format in the letterbox format by the format converter 8), which is the same as that shown in FIGS. 4 (a) and 4 (b).

  While the operator confirms one of the HD format and SD format background images on a monitor or the like, the parameter input operation unit 22 of the operation panel 2 displays the lower corner of the screen as a parameter related to the position where the special effect is to be applied. When the designated parameter is input, the special effect circuit 11 applies the HD format background image of FIG. 9A to the background image of the microcomputer 17 shown in FIG. As shown, the caption (video commentary) is superimposed on the bottom of the 16: 9 screen.

  Further, the SD format background video in FIG. 9B is converted into 4 as shown in FIG. 9D by the special effect circuit 14 based on steps S5 to S6 of the processing of the microcomputer 17 shown in FIG. : The same subtitle is superimposed on the lower end of the 3 screen.

  In this way, subtitles are superimposed on the optimal position (here, the lower end of the screen) corresponding to the respective formats of the background video in two types of formats, the HD format and the SD format.

  10 shows the same background image as shown in FIGS. 5 (a) and 5 (b), and the same sub-screen as shown in FIGS. 5 (c) and 5 (d) and FIGS. 5 (e) and 5 (f). It is a figure which shows a mode that (video of a person) is arrange | positioned.

  FIGS. 10A and 10B show HD format background video and SD format background video (HD format background video sent to the special effect circuit 11 and special effect circuit 14, respectively, in a letterbox format by the format converter 8. This is the same as shown in FIGS. 5 (a) and 5 (b).

  While the operator confirms one of the HD format and SD format background images on a monitor or the like, the parameter input operation unit 22 of the operation panel 2 uses the upper corner of the screen as a parameter related to the position where the special effect is to be applied. Is input to the HD format background image of FIG. 10A by the special effect circuit 11 based on steps S1 to S4 of the processing of the microcomputer 17 shown in FIG. ), A child screen is arranged near the top of the screen.

  Also, the SD format background video in FIG. 10B is displayed on the screen as shown in FIG. 10D by the special effect circuit 14 based on steps S5 to S6 of the microcomputer 17 shown in FIG. A sub-screen is arranged near the top of the screen.

  In this way, with respect to the background video of two types of formats, the HD format and the SD format, the child screen is arranged at the optimum position (here, near the upper end of the screen) according to each format.

  Thus, in this effect switcher, the operator only needs to specify the position on the screen once while confirming either the HD format or the SD format background video on the monitor, etc. , Subtitles are automatically superimposed or sub-screens are placed at optimum positions according to the respective formats on the SD format background video. As a result, a special effect is applied to the optimal position on the screen according to each format of the HD format and SD format images without complicated operations, and the added value is high. Video can be broadcast.

  Here, as shown in FIGS. 9C and 9D and FIGS. 10C and 10D, it is optimum to superimpose subtitles on the HD format background video or to arrange the child screen. The description has been made on the assumption that the position is the same as the optimum position when subtitles are superimposed on the background video in the SD format or the child screen is arranged (both are located at the lower end of the screen or near the upper end of the screen). On the other hand, there is an optimal position when superimposing a subtitle on a HD format background video or arranging a sub-screen, and an optimal position when superposing a subtitle on a SD format background video or arranging a sub-screen. Even if different, if the first adjustment value and the second adjustment value to be stored corresponding to the same parameter in the position adjustment value storage units 19 and 20 are determined accordingly (for example, in FIG. If the second adjustment value corresponding to 1 is determined to be a value other than 75), the optimal position on the screen corresponding to the respective formats of the HD format and the SD format is again used. Special effects can be applied.

  In addition, here, as shown for parameter 1 in FIG. 7, the position adjustment value storage units 19 and 20 correspond to the parameters for designating any of the four corners or edges of the screen as shown in FIG. , (B) are stored as the first adjustment value and the second adjustment value. However, as another example, a position adjustment value corresponding to a parameter that specifies one of the four corners or the edge of the screen is set to a margin value from the edge of the 16: 9 screen in HD format as the first adjustment value. In addition to storing in the storage unit 19, the margin value from the end of the 4: 3 screen in the SD format is stored in the position adjustment value storage unit 20 as the second adjustment value, and in steps S 4 and S 6 of the processing of FIG. The special effect circuits 11 and 14 calculate the coordinates on the screen such that the distance from the edge of the screen becomes the margin value for each format, and superimpose the caption at the position of the coordinates or arrange the sub-screen. May be controlled.

  Alternatively, instead of such a margin value, as illustrated in FIG. 11, parameters for specifying any of the four corners or edges of the screen (here, a parameter for specifying the upper right corner and a parameter for specifying the upper left corner). ), The coordinates (x, y) having a certain margin from the edge of the 16: 9 screen in the HD format (the horizontal and vertical coordinates in% values as shown in FIG. 3A). Is stored in the position adjustment value storage unit 19 as a first adjustment value, and coordinates (x, y) having a certain margin from the end of the 4: 3 screen in the SD format (FIG. 3). A fixed value that directly designates the coordinate in the horizontal and vertical directions by the value of% as in (b) is stored in the position adjustment value storage unit 20 as the second adjustment value, and steps S4 and S6 of the processing of FIG. Now, without calculating the position, It may control the special effect circuit 11, 14 to place the child screen or by superimposing the subtitles on the position of a fixed value for each format.

  Here, as described with reference to FIG. 7, the position adjustment value is defined by using coordinates defining one position on the screen (the lower corner of the screen in parameter 1) as the first adjustment value and the second adjustment value. Stored in the storage units 19 and 20. However, as another example, the positions of the left and right ends or top and bottom ends of the area where special effects are applied (areas where subtitles are superimposed or subscreens are placed), and all the top, bottom, left and right edges of areas where special effects are applied The coordinates defining the position may be stored in the position adjustment value storage units 19 and 20 as the first adjustment value and the second adjustment value.

  Then, by defining the positions of two or more ends of the area where the special effect is applied in this way, the size of the area where the special effect is applied (the size of the subtitle or sub-screen) is determined indirectly on the screen. Therefore, in steps S4 and S6 of the process of FIG. 8, the size of the subtitle or sub-screen selected by the key selection operation unit 21a of the button arrangement unit 21 of the operation panel 2 is adjusted according to the determined size ( For example, if the size of the selected subtitle or sub-screen is larger than the size determined by the adjustment value, make the size of the selected subtitle or sub-screen match the size determined by the adjustment value. It is desirable that the special effect circuit 11 is also controlled.

  Alternatively, information directly indicating the size of the area to which the special effect is applied is also stored in the position adjustment value storage units 19 and 20 as the first adjustment value and the second adjustment value, and in steps S4 and S6 of the process of FIG. Based on the information, the special effect circuit 11 may be controlled so as to adjust the size of the subtitle or sub-screen selected by the key selection operation unit 21a of the button arrangement unit 21 of the operation panel 2.

  Next, FIG. 12 is a diagram showing another example of the overall configuration of the effect switcher to which the present invention is applied. The same reference numerals are given to the same parts as in FIG. In this effect switcher, the first arithmetic program storage unit 31 and the second arithmetic program storage unit are stored in the memory 18 in the microcomputer 17 instead of the area of the position adjustment value storage units 19 and 20 shown in FIG. There are 32 areas. The other hardware configuration is the same as that of the effect switcher of FIG.

  In the arithmetic program storage unit 31, when a parameter related to the position where the special effect is to be applied is input by the parameter input operation unit 22, the first related to the position where the subtitle is superimposed or the child screen is arranged on the 16: 9 screen. A first subroutine for calculating the adjustment value is stored.

  In the arithmetic program storage unit 32, when a parameter related to the position where the special effect is to be applied is input by the parameter input operation unit 22, the second related to the position where the subtitle is superimposed or the child screen is arranged on the 4: 3 screen. A second subroutine for calculating the adjustment value is stored.

  The first subroutine and the second subroutine differ, for example, in the following points. At the time the SD format standard with an aspect ratio of 4: 3 was established, a CRT was generally used as a video display means. However, the CRT has a characteristic that the video cannot be displayed on the upper, lower, left and right edges of the screen. Therefore, when displaying an SD format image, the area excluding the edge of the 4: 3 screen 51 is defined as a safety area S as shown in FIG. It is desirable to be within the range.

  Therefore, when displaying HD format video, even when subtitles are superimposed on the edge of the screen or when a sub-screen is arranged, when displaying SD format video, subtitles are superimposed avoiding the edge of the screen. It is desirable to arrange a child screen. Therefore, in the second subroutine, the coordinates in the safety area are calculated. In the first subroutine, the coordinates are calculated without considering such a safety area.

  FIG. 14 is a diagram exemplifying calculation contents of the first subroutine and the second subroutine when a parameter for specifying the left corner or the right corner of the screen is input and the width of the subtitle or the sub-screen is w%. . In the first subroutine, the screen horizontal coordinate x (coordinate as shown in FIG. 3A) is set to 100-w% (that is, the subtitle or sub-screen is located at the full left or right end of the screen). At the same time, the length of the subtitles and sub-screens in the vertical direction of the screen is set to 200% (that is, the subtitles and sub-screens are fully positioned from the bottom to the top of the screen).

  On the other hand, in the second subroutine, the distance between the left and right edges of the screen and the safety area is d%, and the horizontal coordinate x (coordinate as shown in FIG. 3B) is 100-w-. d% (that is, the coordinates where the subtitles and sub-screens are located at the left end or the right end of the safety area). In addition, the distance between the upper and lower edges of the screen and the safety area is h%, and the length of the subtitle or sub-screen in the vertical direction of the screen is 200− (2 × h)% (that is, the subtitle or sub-screen is It is set to the length that is located fully over the top edge). Also, if the original subtitles or sub-screens in the vertical size do not match the length of 200- (2 × h)%, the vertical length is set to match the length of 200- (2 × h)%. A reduction ratio and an enlargement ratio for adjusting the size in the direction are also calculated.

  Note that the calculation formula shown in FIG. 14 is merely an example, and a calculation formula corresponding to the type of parameter relating to the position to which the special effect is applied may be incorporated into the first subroutine and the second subroutine. Further, different calculation formulas may be incorporated in the first subroutine and the second subroutine in consideration of elements other than the safety area.

  FIG. 15 shows the effect switcher of FIG. 12 when the microcomputer 17 operates the parameter input operation unit 22 (when a signal indicating the operation content of the parameter input operation unit 22 is sent from the microcomputer 23 of the operation panel 2). It is a flowchart which shows the process performed to). In this process, first, information indicating the parameter type K input by the parameter input operation unit 22 is acquired (step S11).

  Subsequently, it is determined whether or not the type K parameter is an item common to the HD format and the SD format (step S12). If no, the first subroutine corresponding to the type K parameter is called from the arithmetic program storage unit 31, and the first adjustment value p1 is calculated by the subroutine (step S13).

  A position based on the adjustment value p1 (for example, if the adjustment value p1 is x = 100−w% and y = 200% in FIG. 14), the screen is full at the left or right end and full from the lower end to the upper end of the screen. The special effect circuit 11 is controlled so as to superimpose subtitles or arrange a sub-screen at the position (step S14).

  Subsequently, the second subroutine corresponding to the type K parameter is called from the arithmetic program storage unit 32, and the second adjustment value p2 (and the size reduction ratio and the enlargement ratio if necessary) are calculated by the subroutine. (Step S15).

  Subsequently, if the position based on the second adjustment value p2 (for example, if the adjustment value p2 is x = 100−w−d%, y = 200− (2 × h)% in FIG. 14), the left end of the safety area Alternatively, the special effect circuit 14 is controlled so as to superimpose subtitles or arrange a sub-screen on the right end and the full position from the lower end to the upper end of the safety area (step S16). Then, the process ends.

  If YES in step S12, the special effect circuits 11 and 14 are controlled by the type K parameter (steps S17 and S18), and the process is terminated. Note that the parameter w used for the calculation in steps S13 and S15 may be input from the parameter input operation unit 22 (taken in step S11), or may be stored in another storage area (corresponding to the input line of subtitles). You may make it memorize.

  Next, in the effect switcher of FIG. 12, the same input line is selected by the background video selection switch 10 of the bank 5 and the background video selection switch 13 of the bank, and the key video selection switch 9 of the bank 5 and the key of the bank 6 are selected. A description will be given of how a video of the same input line is selected by the video selection switch 12 and a special effect is simultaneously applied by the special effect circuit 11 and the special effect circuit 14.

  FIG. 16 is a diagram showing a state in which vertical subtitles are superimposed on the background video in the HD format and SD format when the first subroutine and the second subroutine are the calculation formulas shown in FIG. FIGS. 16A and 16B show an HD format background video and an SD format background video (HD format) sent from the background video selection switch 10 and the background video selection switch 13 to the special effect circuit 11 and the special effect circuit 14, respectively. The background video is converted to the SD format in the letterbox format by the format converter 8).

  While the operator confirms one of the HD format and SD format background images on a monitor or the like, the parameter input operation unit 22 of the operation panel 2 uses the right corner of the screen as a parameter related to the position where the special effect is to be applied. 16 is input to the HD format background image of FIG. 16A by the special effect circuit 11 based on steps S11 to S14 of the processing of the microcomputer 17 shown in FIG. As shown in (), a vertical subtitle (vertical character string) is superimposed at the right end of the 16: 9 screen and at the full position from the lower end to the upper end of the screen.

  Also, the background image of the SD format in FIG. 16B is the same as shown in FIG. 16H by the special effect circuit 14 based on steps S15 to S16 of the processing of the microcomputer 17 shown in FIG. The subtitle (however, the vertical size is adjusted) is superimposed at the full position of the right end of the safety area S on the 4: 3 screen and from the lower end to the upper end of the safety area S.

  In this way, the optimal position corresponding to each format for the background video of the two formats of HD format and SD format (here, the HD format is a position where the display area is fully utilized, and the SD format is Subtitles are superimposed at a position where the effective display area is fully utilized while considering the safety area.

  FIGS. 16C and 16D show a comparison of the same subtitles superimposed on the HD format and SD format background video by the conventional method shown in FIG. FIGS. 16 (e) and 16 (f) show a comparison between the same subtitles superimposed on the HD format and SD format background video by the conventional method shown in FIG. In FIG. 16D, captions are superimposed on the right end of the 4: 3 screen (outside the safety area shown in FIG. 13). Further, in FIG. 16F, captions are superimposed on the right edge, upper edge, and lower edge (outside the safety area S) of the 4: 3 screen. Accordingly, none of the subtitles can be superimposed at the optimum position in consideration of the safety area in the SD format video.

  FIG. 17 is a diagram showing a state in which small screens are arranged on background images in HD format and SD format (the first subroutine and the second subroutine are different from the calculation formulas shown in FIG. 14). ). FIGS. 17A and 17B show an HD format background video and an SD format background video (here, respectively) sent from the background video selection switch 10 and the background video selection switch 13 to the special effect circuit 11 and the special effect circuit 14, respectively. The background video in HD format is converted to the SD format in a format in which the left and right parts of the screen are cut by the format converter 8).

  While the operator confirms one of the HD format and SD format background images on a monitor or the like, the upper left corner of the screen is used as a parameter related to the position where the special effect is to be applied in the parameter input operation unit 22 of the operation panel 2. 17 is input to the HD format background image shown in FIG. 17A by the special effect circuit 11 based on steps S11 to S14 of the processing of the microcomputer 17 shown in FIG. ), A sub-screen (person's video) is arranged almost at the upper left corner of the 16: 9 screen.

  Also, the background image in the SD format of FIG. 17B is the same as shown in FIG. 17H by the special effect circuit 14 based on the processing steps S15 to S16 of the microcomputer 17 shown in FIG. A sub-screen (though reduced in size in the horizontal and vertical directions) is arranged in the upper left corner of the safety area S of the 4: 3 screen.

  In this way, the optimal position corresponding to each format for the background video of the two formats of the HD format and the SD format (here, the position where the HD format makes full use of the display area, the SD format) Then, the sub-screen is arranged at a position where the effective display area is fully utilized while considering the safety area.

  FIGS. 17 (c) and 17 (d) show a comparison of a state in which the same sub-screen is arranged on a background video in HD format and SD format by the conventional method shown in FIG. FIGS. 17 (e) and 17 (f) show a comparison between the same child screens arranged in the HD format and SD format background images by the conventional method shown in FIG. In FIG. 17D, a part of the sub-screen is cut off, and the subtitle is superimposed on the left end (outside the safety area S) of the 4: 3 screen. In FIG. 17F, captions are superimposed on the upper and left ends (outside the safety area S) of the 4: 3 screen. Therefore, none of the subtitles can be superimposed at an optimal position in the SD format video.

  As described above, even in the effect switcher shown in FIG. 12, the operator only needs to specify the position on the screen once while confirming either the HD format or the SD format background video on the monitor or the like. Subtitles are automatically superimposed or sub-screens are placed at optimum positions according to the respective formats of the HD format and SD format background images. As a result, a special effect is applied to the optimal position on the screen according to each format of the HD format and SD format images without complicated operations, and the added value is high. Video can be broadcast. Of course, it is possible to define a safety area for the HD format and control it with a calculation formula for the HD format. As described above, the effect switcher of FIG. 12 can perform more complicated control for each format than simply storing the adjustment value for each format.

  In this case, the memory 18 in the microcomputer 17 is provided with areas for the operation program storage units 31 and 32, and the microcomputer 17 calls a subroutine in these operation program storage units 31 and 32 to thereby obtain the first adjustment value. The second adjustment value is calculated. However, as another example, a dedicated arithmetic circuit for calculating each of the first adjustment value and the second adjustment value is provided, and the microcomputer 17 uses the special effect circuit 11, based on the calculation result of the arithmetic circuit. 14 may be controlled.

  In the above example, the present invention is applied to superimpose subtitles on the background video or to arrange the sub-screen. However, the present invention applies other special effects to a part of the background video. It may also be applied when applied.

  In the above example, the present invention is applied to the effect switcher. However, the present invention is also applied to a device other than the effect switcher, which applies special effects to two types of formats at the same time. It's okay.
