[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a camera photographing control system using a master side camera by human operation and a robot camera for automatic photographing in sports television broadcasting and the like, and particularly competes for times such as skies, schedules and tracks. The present invention relates to a camera photographing control system that is optimal for viewing and comparing a plurality of competitors (players) in an instant when photographing and broadcasting or recording a competition.
[0002]
[Prior art]
When sports competitions such as skies and marathons are broadcasted on television, photographers shoot and broadcast at various angles and angles of view. It is requested that the competitor being aired displays on the screen how fast or slow the competitor who is first in time is. This is because, in the middle of the competition, in general, the psychology of wanting to enjoy while predicting the current competitor's ranking and record works.
[0003]
For this reason, in the past, the lap time at an appropriate intermediate position (for example, 100 m from the start position when skiing down) is sequentially measured, and for example, for a competitor who is first (or second, third, etc.) The degree of difference is displayed as a number (time) on the TV screen. In addition, a small space sub-screen is provided at the corner of the main screen at the center of the screen to display the current competitor on the main screen and other competitors recorded in the video to the sub-screen. It may be displayed.
[0004]
[Problems to be solved by the invention]
As described above, when the time difference from other competitors is displayed numerically on the TV screen, it is unclear how much the distance is different, and there is a drawback that the difference cannot be realized. Also, when displaying on the main screen and the sub-screen, there is a drawback that the relative superiority or inferiority of the two players cannot be grasped because the shooting conditions such as zoom and panning are different.
[0005]
The present invention has been made under the circumstances as described above, and the object of the present invention is to allow a current player to play other athletes (for example, when a sporting event such as skiing or marathon is broadcast on television). Camera shots to show both competitors on the screen under the same conditions so that they can instantly see how fast or slow it is for the highest time competitor at that time) To provide a control system.
[0006]

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a configuration example of the present invention. A master side camera 10 that is manually operated by a cameraman is installed in a stadium such as a ski field, and the master side camera 10 has a panning speed of the camera. Detection means 11 for detecting Vp, tilting speed Vt and zoom amount θ (including focus, iris, etc.) is provided. The panning speed Vp, tilting speed Vt, and zoom amount θ detected by the detection means 11 are transmitted to the measurement CPU (personal computer) 20 as a detection signal DS and output according to the competitor's start. The measurement signal ST is also input to the measurement CPU 20, and the measurement CPU 20 measures the camera data, receives the start signal ST, holds the internal timer, and transmits an initialization signal NS to the detection means 11. The measurement CPU 20 is connected to a system CPU (personal computer) 30 and is generated based on the start signal ST in addition to the storage data of the panning speed Vp, the tilting speed Vt, and the zoom amount θ from the measurement CPU 20 to the system CPU 30. A measurement start signal ts and a measurement end signal te are transferred as processing information PSA, and the system CPU 30 further includes official data such as player numbers, player times (goal records), temperature, humidity, wind direction, and wind speed. (Official record information) OD is input.
[0008]
As shown in FIG. 2, the system CPU 30 stores the processing information PSA sequentially as a file with a file name, and selects one of them as a reference file on the operation panel 31. The system CPU 30 stores data such as panning obtained by the measurement start signal ts and the measurement end signal te, and loads the reference file selected on the operation panel 31 to the control CPU (personal computer) 40 in the next stage. Do. That is, the reference data RD, the measurement start signal ts, and the measurement end signal te are transferred from the system CPU 30 to the control CPU 40 as processing information PSB.
[0009]
The robot camera 50 that automatically shoots is also installed at almost the same position in the same stadium as the master side camera 10 so that the player can be photographed under the same conditions. The robot camera 50 uses the reference data RD from the control CPU 40. Is driven via the drive circuit 41. The video signal VSM from the master-side camera 10 is input to the recording device 2 and recorded, and the video signal VSMT with a time code is input to the image processing device 1. The video signal VSR from the robot camera 50 is directly input to the image processing apparatus 1, processed by the image processing apparatus 1 and then displayed on the display apparatus 3, or via a radio wave 4 at a television receiver at home or the like. The viewer will see the two competitors simultaneously comparing. Here, the recording apparatus 2 and the image processing apparatus 1 are managed and controlled by a system CPU 30 as described later.

In the superimposed display, the master side camera 10 and the robot camera 50 are installed at substantially the same position, but the background of the master side camera 10 and the background of the robot camera 50 do not completely coincide with each other. The apparatus 1 removes the background by extracting the video signal VSMT from the recording apparatus 2, for example, by extracting at least a specific image area including the player and extracting a colored signal component in this area. It is displayed as a hollow image. The background removal may be performed on the video signal VSR.
[0011]
FIG. 3 shows an installation example of the master side camera 10 and the robot camera 50 by taking a ski runway as an example, and the master side camera 10 is located at substantially the same position in a high place where the ski runway can be photographed. In addition, a robot camera 50 is installed. A gate 6 is provided at the start position of the ski player 5, and when the ski player 5 starts across the gate 6, a start signal ST is automatically output and the start signal ST is output. The signal ST is input to the measurement CPU 20. The area AR1 in FIG. 3 is a range in which the video that follows the player 5 with the master-side camera 10 and the robot camera 50 is used as a broadcast material. The end signal te is set to be output, and the area AR2 between the measurement start signal ts and the measurement end signal te is a range in which data is taken. In addition, the time when the player 5 is goled is separately measured and input to the system CPU 30 as official data OD.
[0012]
FIG. 4 shows the structure of the robot camera 50 and its control system. The robot camera 50 is placed on a pan head. The imaging unit 51 of the robot camera 50 is controlled in the horizontal direction (pan) and the vertical direction (tilt) by the rotation of the pan axis 54 and the tilt axis 55 by driving the motors 52 and 53, and further, the imaging unit 51 is shifted. The motor, focus, iris, etc. are controlled by driving the motor 56.
[0013]
In such a configuration, the operation will be described with reference to the flowcharts of FIGS. FIG. 5 shows an operation example on the measurement side from the initialization of the master side camera 10 to the update of the reference data RD, and FIG. 6 shows an operation example on the robot camera 50 side.
[0014]
When the operation is started on the measurement side, the measurement CPU 20 first transmits an initialization signal NS to the detection unit 11 of the master side camera 10, and the detection unit 11 is previously held at the origin position by the cameraman. After the panning data and tilting data are initialized (step S11), the zoom amount is initialized (step S12). The system CPU 30 reads the official data OD such as the player number that has been input (step S13), and waits until the start signal ST output by the player start is obtained (step S14). The measurement CPU 20 starts a built-in timer in response to a start signal ST output when the player starts (step S15), and monitors the timer (step S16). The measurement CPU 20 generates a measurement start signal ts (step S20) when the elapsed time reaches the preset measurement start time (step S17) by the monitor of the timer (step S20). The measuring means 11 measures the panning speed Vp, the tilting speed Vt, and the zoom amount θ (step S21). The photographing by the master camera 10 and the measurement by the measuring means 11 are continued until the preset measurement end time (step S22), and the measurement end signal te is generated when the measurement end time is reached (step S22). S23). During the period from the measurement start signal ts to the measurement end signal te, the recording device 2 records the video signal VSM from the master-side camera 10, and the system CPU 30 stores measurement data such as panning (step S24).
[0015]
The system CPU 30 determines whether or not the reference data needs to be updated (step S25). If it is not necessary, the system CPU 30 returns to step S13. If necessary, the reference data file is returned as shown in FIG. The name is updated (step S26). Whether or not the reference data can be updated depends on whether or not the player 5 has goled, since the time is sequentially input and held in the system CPU 30 as the official data OD. Judgment will be made by comparing the results. If the current player's score exceeds the registered player's score, the current player's data is updated as the reference data RD.
[0016]
The updated master-side camera 10 repeats the same operation as described above for subsequent players, but the initialization operation (steps S10 to S12) at the time of repetition can be omitted in a series of competitions.
[0017]
On the other hand, as shown in FIG. 6, in the operation on the robot camera 50 side, first, initialization of the robot camera 50 (step S30) is performed in the same manner as the master side camera 10, and it is determined whether or not it is the first player (step S31). For the second and subsequent players, the control CPU 40 reads the panning speed Vp, tilting speed Vt, and zoom amount θ of the player with the file name of the reference data RD selected above (step S32). ). The robot camera 50 waits at the first data position (step S33), waits for the measurement start signal ts to be input (step S34), and when the measurement start signal ts is input, the robot camera 50 passes through the drive circuit 41. The camera 50 is driven (step S35). The robot camera 50 can shoot automatically following in accordance with the reference data RD, that is, shoot the current player under the same movement and conditions as the highest recorded player so far, and transmit the video signal VSR. The driving and photographing of the robot camera 50 are continued until the measurement end signal te is input (step S36), and when the measurement end signal te is input, the operation of the robot camera 50 for the player is ended (step S37).
[0018]
When the robot camera 50 is driven to photograph the player 5, the system CPU 30 controls the recording device 2 and the image processing device 1, and the image processing device uses the player image corresponding to the reference data RD as the video signal VSMT. 1 to send. The image processing device 1 performs image processing on the video signals VSR and VSMT, and displays them superimposed on the display device 3 as shown in FIG. Thereby, the person who is viewing the video can realize on the screen the difference at the midpoint between the current player and the player with the highest time. Further, the screen display on the display device 3 may be a parallel display by screen division as shown in FIG. In either case, the current player's time is displayed numerically, and the delay or advance is also displayed in time, which makes it easier to understand.
[0019]
In the above-described embodiment, the video signal VSR from the robot camera 50 is directly input to the image processing apparatus 2 to display an image. However, the video signal VSR is recorded in the recording apparatus and the recorded image is displayed. Anyway. In the above description, the measurement CPU 20, the system CPU, and the control CPU are distributed and configured. However, these can be combined into one personal computer. Further, in the above description, the reference data RD is the player with the highest time, but any player can be selected as appropriate. Furthermore, in the above description, the ski is taken as an example, but the present invention can also be applied to a case where different players repeatedly move in the same place.
[0020]
