<2. Operation of video processing device>
Next, the operation of the video processing apparatus 10 will be described. The video processing device 10 changes the setting of the imaging device in conjunction with video processing. In this case, for example, when the transition lever 144 is set as one end point, the video processing device 10 has a first imaging device and a second imaging device that individually set a first imaging device that outputs a video signal used for video processing. The imaging is performed as the operation state based on the one linkage setting information. In addition, when the transition lever 144 is set to the other end point, the video processing device 10 operates based on second interlocking setting information in which the first imaging device and the second imaging device are individually set for the imaging device. The imaging operation is performed. Furthermore, when the transition lever 144 is operated, the video processing device 10 performs an operation according to the operation position within an operation variable range based on the first linkage setting information and the second linkage setting information. To control. In the following description, the video processing unit performs video synthesis using the first imaging device and the second imaging device, and zooms between the first imaging device and the second imaging device in conjunction with the video synthesis operation. The case where operation is performed is shown.

  FIG. 3 is a flowchart showing the operation setting information storing process. In step ST <b> 1, the control unit 18 of the video processing device 10 performs processing for selecting an imaging device to be operated. The control unit 18 determines an operation target imaging device whose setting is changed by the user operating the joystick 146 by a user operation on the operation target selection button 145. In addition, the control unit 18 controls the cross point switch 11 to select a video signal from the determined imaging device and output the selected video signal to the video processing unit 12. Further, the control unit 18 controls the video processing unit 12 to output the video signal selected by the cross point switch 11, and proceeds to step ST2.

  In step ST2, the control unit 18 controls the operation of the imaging apparatus according to a user operation. The control unit 18 determines a user operation on the joystick 146 and outputs a control signal corresponding to the determined user operation to the drive processing unit corresponding to the operation target imaging device selected in step ST1. The drive processing unit supplied with the control signal outputs a drive signal for driving the imaging apparatus to the operation target imaging apparatus based on the control signal, thereby controlling the operation target imaging apparatus in accordance with a user operation. Proceed to ST3.

  In step ST3, the control unit 18 determines whether or not a storage operation has been performed. When the save operation is performed, for example, when the save button 147 is operated, the control unit 18 proceeds to step ST4, and when the save operation is not performed, the control unit 18 proceeds to step ST7.

  In step ST4, the control unit 18 determines whether or not a registration number is designated. When the registration number when the operation setting information for setting the operation target imaging apparatus as the current zoom position is stored in the setting storage unit 17 is designated, the control unit 18 designates the registration number by operating the operation knob 148, for example. If so, the process proceeds to step ST5. Moreover, the control part 18 progresses to step ST6, when the registration number is designated.

  In step ST5, the control unit 18 performs an operation setting information storage process. The control unit 18 stores the operation setting information in which the operation target imaging device is the current zoom position in the setting storage unit 17 as the operation setting information of the designated registration number, and proceeds to step ST7.

  In step ST6, the control unit 18 sets temporary operation setting information. The control unit 18 proceeds to step ST7 using, as temporary operation setting information, operation setting information with the operation target imaging device as the current zoom position.

  In step ST7, the control unit 18 determines whether or not the registration is completed. The control unit 18 returns to step ST1 when it is not determined that the registration is completed, and ends the saving process when it is determined that the registration is completed. For example, when a button operation for ending the saving process is performed, or when an imaging device used for the video processing process is selected, it is determined that the registration is completed, and the saving process is ended.

  FIG. 4 illustrates the operation setting information stored in the setting storage unit. For example, it is assumed that the imaging device 30-1 connected to the drive processing unit 13-1 is selected by the operation of the operation target selection button 145, and the registration number “1” is designated by the operation knob 148. In this case, as shown in FIG. 4A, the control unit 18 sets operation setting information PSc1-E1 that sets the imaging device 30-1 as a zoom position when the save button 147 is operated, as shown in FIG. The setting is stored in the setting storage unit 17. Thereafter, it is assumed that the zoom position of the imaging device 30-1 is changed according to the operation of the joystick 146, and the registration number “2” is designated by the operation knob 148. In this case, the control unit 18 causes the setting storage unit 17 to store the operation setting information as the zoom position when the save button 147 is operated as the operation setting information PSc1-E2. Further, when the imaging device 30-2 is selected by the operation of the operation target selection button 145 and the registration number is specified or the save button is operated, the control unit 18 is operated when the save button 147 is operated. Operation setting information for the zoom position is stored in the setting storage unit 17. For example, it is stored as operation setting information PSc2-E1 of the designated registration number “1”. Further, by performing the same operation on the imaging devices 30-3 and 30-4, as shown in FIG. 4A, operation setting information is stored for each registration number for each imaging device. Can be made.

  In addition, when the save button 147 is operated in a state where the registration number is not specified, the control unit 18 sets the operation setting information as the current zoom position as temporary operation setting information. For example, it is assumed that the imaging device 30-1 connected to the drive processing unit 13-1 is selected by operating the operation target selection button 145, and the save button 147 is operated without specifying a registration number. In this case, the control unit 18 uses the temporary operation setting information PSc1-E0 as the operation setting information that sets the imaging device 30-1 as the zoom position when the save button 147 is operated, as shown in FIG. And In addition, when an imaging device connected to another drive processing unit is selected by operating the operation target selection button 145 and a zoom operation or a save button 147 is performed, an operation for setting each imaging device to the current zoom position. The setting information is provisional operation setting information.

  Next, an interlocking operation for interlocking the image composition and the zoom position will be described with reference to the flowchart of FIG. The linked operation may be performed subsequent to the operation setting information storing process or may be performed separately from the operation setting information storing process.

  In step ST <b> 11, the control unit 18 performs processing for selecting an imaging device to be operated. As in step ST1, the control unit 18 determines the imaging device selected by the user using the operation target selection button 145, and outputs a video signal from the imaging device that is the determined operation target from the video processing processing unit 12. Proceed to step ST12.

  In step ST12, the control unit 18 controls the operation of the imaging device in accordance with a user operation. As in step ST2, the control unit 18 outputs a drive control signal corresponding to the user operation to the drive processing unit corresponding to the operation target imaging device selected in step ST11, and proceeds to step ST13.

  In step ST <b> 13, the control unit 18 determines whether an imaging device used for the video processing process has been selected. The control unit 18 proceeds to step ST14 when the imaging device that generates the video signal used for the video processing process is selected, and returns to step ST11 when the imaging device is not selected. For example, the control unit 18 operates the first imaging device selection button 141 and the second imaging device selection button 142 to generate the video signals used for the video processing process. When it is selected, the process proceeds to step ST14.

  As described above, by performing the processing from step ST11 to step ST13 and repeating the processing of step ST11 and step ST12, the user can set the zoom position of each imaging apparatus. In addition, the control unit 18 sets the zoom position set by the processing from step ST11 to step ST13 as the interlock start position in the interlock operation. Note that the setting of the zoom position only needs to be performed for the imaging device used for the video processing.

  In step ST14, the control unit 18 determines whether or not the transition lever 144 is an end point. The control unit 18 returns to step ST14 when the transition lever 144 is not at the end point, and proceeds to step ST15 when the transition lever 144 is at the end point.

  In step ST15, the control unit 18 sets the first linkage setting information. The control unit 18 proceeds to step ST16 with the operation setting information that sets the imaging device selected in step ST13 as the current zoom position as the first interlocking setting information. For example, it is assumed that the imaging device 30-1 is selected as the first imaging device and the imaging device 30-3 is selected as the second imaging device. In this case, as shown in FIGS. 6A and 6B, when the transition lever 144 is at the end point LA, the control unit 18 operates the imaging device 30-1 as the current zoom position. The setting information PSc1-S is set as the first linkage setting information of the imaging device 30-1. Further, the operation setting information PSc3-S with the imaging device 30-3 as the current zoom position is set as the first interlock setting information of the imaging device 30-3.

  In step ST16, the control unit 18 selects a video processing process in accordance with a user operation. The control unit 18 determines the video processing process selected by the user by operating the video processing process selection button 143. Further, the control unit 18 sets the operation of the video processing unit 12 so that the determined video processing is performed, and proceeds to step ST17. For example, when the video processing process for combining the video signals generated by the imaging devices 30-1 and 30-3 is selected as the video processing process, the control unit 18 performs the synthesis of the two video signals. The operation of the video processing unit 12 is set.

  In step ST17, the control unit 18 sets the second interlocking setting information. When the interlock button 149 is operated and the interlock mode is selected, the control unit 18 sets the temporary operation setting information set in step ST5 to the second interlock setting information, and proceeds to step ST18. For example, it is assumed that the imaging device 30-1 is selected as the first imaging device and the imaging device 30-3 is selected as the second imaging device. In this case, as shown in FIG. 6A, the second interlocking setting information of the first imaging device is provisional operation setting information PSc1-E0, and the second interlocking setting information of the second imaging device is provisional operation setting information PSc3. -E0.

  In step ST18, the control unit 18 determines whether or not an operation setting information read operation has been performed. The control unit 18 proceeds to step ST19 when the operation setting information read operation is performed, and proceeds to step ST21 when the read operation is not performed.

  In step ST19, the control unit 18 reads the operation setting information. The control unit 18 reads the operation setting information of the registration number designated by the user operation from the operation setting information stored corresponding to the imaging device used for the video processing, and proceeds to step ST20.

  In step ST20, the control unit 18 performs a process for updating the second interlocking setting information. The control unit 18 updates the second interlocking setting information using the operation setting information read in step ST19, and proceeds to step ST21.

  For example, the imaging device 30-1 is selected as the first imaging device, and the imaging device 30-3 is selected as the second imaging device. The registration number “3” for the imaging device 30-1 and the registration number “3” for the imaging device 30-3 are selected. It is assumed that the operation setting information “1” is read out. In this case, as shown in FIG. 6B, the second linkage setting information of the first imaging device is the operation setting information PSc1-E3, and the second linkage setting information of the second imaging device is the operation setting information PSc3-E1. Become.

  In step ST21, the control unit 18 performs an interlocking operation. The control unit 18 changes the processing in the video processing and the operation of the imaging device according to the operation position of the transition lever 144. For example, when the transition lever 144 is at one end point LA, the first imaging device and the second imaging device are set to zoom positions based on first interlocking setting information individually set for the imaging device. When the transition lever 144 is set to the other end point LB, the first imaging device and the second imaging device are set to the zoom positions based on the second interlocking setting information individually set for the imaging device. Further, when the transition lever 144 is moved from the end point, the control unit 18 changes the zoom position with the movement of the transition lever 144 from the zoom position based on the first interlock setting information to the zoom position based on the second interlock setting information. Let Alternatively, the control unit 18 changes the zoom position with the movement of the transition lever 144 from the zoom position based on the second interlock setting information to the zoom position based on the first interlock setting information. Further, the image composition ratio is changed in accordance with the movement of the transition lever 144, and the zoom operation of the first image pickup device and the second image pickup device is linked with the image composition operation. Thereafter, the controller 18 ends the interlock operation when the interlock button 149 is operated again and the interlock mode is released.

  If such processing is performed, the first linkage setting information and the second linkage setting information corresponding to the imaging device are individually set for each of the first imaging device and the second imaging device. Further, when the transition lever 144 is operated, the video is synthesized according to the position of the transition lever 144. Furthermore, the zoom position of the first imaging device and the zoom position of the second imaging device are changed according to the position of the transition lever 144 within the zoom variable range based on the first linkage setting information and the second linkage setting information. Therefore, it is possible to easily obtain various and high-quality editing effects by linking the video composition and the zooming operation of the imaging apparatus.

  Further, the operation setting information used for one end point of the transition lever 144 is stored, and when the transition lever 144 is set to the other end point to enter the interlocking mode, the operation setting information as the current zoom position becomes the other interlocking setting information. Set to Therefore, the zoom variable range according to the position of the transition lever 144 can be easily set. In addition, since the interlock setting information is set in correspondence with the end point of the transition lever 144, the zoom position when the transition lever 144 is operated may exceed the zoom variable range determined by the two interlock setting information. Absent.

<3. Editing operation example>
Next, an editing operation in which video composition and an imaging device are linked will be exemplified. 7A is the zoom position of the first imaging device (for example, the imaging device 30-1), FIG. 7B is the video signal output from the video synthesis unit, and FIG. The zoom position of the 2nd image pick-up device (for example, image pick-up device 30-3) is illustrated. FIG. 7D shows the operation position of the transition lever 144. In FIGS. 7A and 7C, “T” indicates the tele end position and “W” indicates the wide end position.

  When the transition lever 144 is set to the end point LA, the control unit 18 sets the operation setting information PSc1-S with the first imaging device as the current zoom position as the first linkage setting information of the first imaging device. Further, the control unit 18 uses the operation setting information PSc3-S with the second imaging device as the current zoom position as the first interlock setting information of the second imaging device.

  When the operation setting information is read and the operation setting information with the registration number “3” is read from the imaging device 30-1 as the first imaging device, the control unit 18 reads the operation setting information. PSc1-E3 is set in the second linkage setting information. When the operation setting information with the registration number “1” is read out from the imaging device 30-2 as the second imaging device, the control unit 18 uses the read operation setting information PSc3-E1 as the second interlocking setting information. Set to.

  Thereafter, the control unit 18 synthesizes the video signals of the first imaging device and the second imaging device in accordance with the operation position of the transition lever 144 as shown in FIG. Further, the zoom variable range is determined by each of the first imaging device and the second imaging device based on the first linkage setting information and the second linkage setting information so that the zoom position corresponds to the operation position of the transition lever 144. The first imaging device and the second imaging device are driven.

  In this case, for example, when the transition lever 144 is moved from the end point LA to the end point LB, the image of the first image pickup device is zoomed out while the image of the second image pickup device is zoomed in, and the image of the first image pickup device is zoomed out. Can be switched to the image of the second imaging device. In addition, since the image composition and the zoom operation are performed in conjunction with each other, the zoom operation is not delayed or too fast with respect to the image composition, and high-quality editing processing can be easily performed. For example, at the wedding hall, the imaging device 30-1 performs zooming out of the entire ceremony hall, and the imaging device 30-3 is set to zoom in on the hand for exchanging the ring. With such a setting, it is possible to record a scene in which the entire ceremony hall is switched to the ring exchange only by operating the transition lever 144 in conjunction with the image composition and the zoom operation.

  In addition, the video processing apparatus is not limited to the case where the zoom position of the imaging apparatus is changed according to the operation position of the transition lever 144. For example, a panning operation or a tilting operation is performed, and the imaging direction is determined according to the operation position of the transition lever 144. May be changed. Further, the focus state of the imaging apparatus, the iris opening state, the white balance, etc. may be changed according to the operation position of the transition lever 144, and these settings are combined to automatically change according to the operation position of the transition lever 144. It may be changed to.

  When the imaging direction is automatically changed according to the operation position of the transition lever 144, for example, the first imaging device and the second imaging device are moved in the same direction while the first imaging device image is captured in the second imaging mode. An editing process of switching to the device image can be easily obtained.

  When the focus is changed according to the operation position of the transition lever 144, for example, the image of the first imaging device is erased while decreasing the sharpness so that the image of the second imaging device appears while increasing the sharpness. Editing processing can be performed easily.

  When changing the exposure state in accordance with the operation position of the transition lever 144, for example, iris, shutter speed, gain adjustment, etc. are performed so that the brightness of the subject on the image can be varied, so that the image of the first imaging device can be changed. Switching to the image of the second imaging device while increasing the luminance. In addition, the image of the 21st imaging device is controlled so as to be an image with appropriate luminance from the state where the luminance is increased. Further, the image may be switched while lowering the luminance. In this way, it is possible to easily switch the video by interlocking the luminance.

  Further, if a plurality of settings such as the zoom position and the imaging direction are changed in conjunction with the video processing process, various editing processes can be performed easily and with high quality.

  Further, when controlling the operation of the imaging device in conjunction with the video processing according to the operation position of the transition lever 144, the operation of the imaging device is changed in accordance with the change in the operation of the video processing. Also good. FIG. 8 illustrates a case where the operation of the imaging device is changed in response to a change in the operation of the video processing process.

  8A is the zoom position of the first imaging device (for example, the imaging device 30-1), FIG. 8B is the video signal output from the video processing unit, and FIG. The zoom position of the second imaging device (for example, the imaging device 30-3) is illustrated. Further, FIG. 8D shows the operation position of the transition lever 144. In FIGS. 8A and 8C, “T” indicates a tele end position, and “W” indicates a wide end position.

  When the transition lever 144 is set to the end point LA, the control unit 18 sets the operation setting information PSc1-S with the first imaging device as the current zoom position as the first linkage setting information of the first imaging device. Further, the control unit 18 uses the operation setting information PSc3-S with the second imaging device as the current zoom position as the first interlock setting information of the second imaging device.

  When the operation setting information is read out and the operation setting information with the registration number “3” is read out from the imaging device 30-1 as the first imaging device, the control unit 18 reads out the operation setting information. The setting information PSc1-E3 is set as the second linkage setting information. When the operation setting information with the registration number “1” is read out from the imaging device 30-2 as the second imaging device, the control unit 18 uses the read operation setting information PSc3-E1 as the second interlocking setting information. And

  Here, when the image level is switched with the signal level of the imaging devices 30-1 and 30-2 set to “0” when the transition lever 144 is at the center position, the signal level of the imaging devices 30-1 and 30-2 is set. The zoom position is changed according to the change in. That is, when the transition lever 144 is set to the center position, the imaging device 30-1 changes so as to be a zoom position based on the operation setting information PSc1-E3, and the imaging device 30-2 changes to a zoom position based on the operation setting information PSc3-E1. Let

  In this case, if the zoom variable range is set based on the first linkage setting information and the second linkage setting information and the zoom position is linearly changed according to the position of the transition lever 144, for example, the signal level of the imaging device 30-1 is changed. When attenuated to “0”, the zoom position is half the zoom variable range. Therefore, the remaining zoom variable range does not contribute to the image of the imaging device 30-1. However, if the zoom position is changed as shown in FIG. 8 in accordance with the change in the operation of the video processing process, the zoom operation according to the video processing process can be performed. If the change characteristic of the video signal is curved, the change in the zoom position may be curved according to the change characteristic of the video signal.

  Also, when performing video switching, picture-in-picture operation, etc., as well as video synthesis as video processing processing, the zoom position, focus, white balance, etc. are changed according to the processing characteristics of the video processing processing. In this way, it is possible to control the imaging apparatus corresponding to the video processing process in conjunction with only the operation of the transition lever 144, and it is possible to easily obtain various and high-quality editing effects.
