DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a TV broadcast signboard advertisement effect research system for checking the advertisement effect of a signboard advertisement displayed on a TV screen, for example, to a viewer in TV broadcast.

[0002]

2. Description of the Related Art For example, games such as baseball, soccer, volleyball, and rugby are carried out in a predetermined game space such as a baseball stadium, soccer field, indoor stadium, or the like. In these baseball stadiums, soccer stadiums, and indoor stadiums, many companies and organizations, including sponsors of the competitions to be held, have installed a large number of signboard advertisements for their own publicity in a position that can be seen by spectators. I have.

[0003] In some cases, competitions held in such stadiums are broadcasted on TV and watched on TV receivers at homes. In some cases, only the highlight portion of a sports news program is broadcasted on TV.

[0004] In companies and organizations that install signboard advertisements in these stadiums, it is necessary to verify not only how much the signboards appeal to the spectators in the stadium, but also that the competition is T
In the case of V broadcast, a signboard often appears on the background of the competitor on the TV screen. In this case, verifying how much the signboard appeals to a TV viewer is also an important verification item for signboard installation.

[0005]

In general, it is clear that it is desirable to place a sign at a position where a TV camera often takes pictures. However, these are qualitative judgments, and the sign is set at that position. It is not possible to quantitatively verify the advertising effect of the signboard advertisement that was placed.

In order to avoid such a situation, a method of recognizing a still image at a 1/30 second interval constituting a moving image of a TV and recognizing a sign included in the still image can be considered. Considering that the size of the signboard on the still image changes due to heavy use of the zoom and the like, a large processing time is required for the image recognition process, which is not practical.

[0007] Further, in TV broadcasts of sports such as soccer or the like, in which the movement is intense, the camera direction of the TV camera changes frequently and at a high speed. There is a concern that the viewer cannot recognize the contents of the signboard from the TV screen being viewed.

The present invention has been made in view of such circumstances, and can detect a signboard included in a relayed TV image by using a simple software method other than the image recognition method. The number of appearances of signboards can be counted, and T
It is an object of the present invention to provide a TV broadcast signboard advertisement effect research system capable of quantitatively verifying the advertisement effect of a signboard advertisement displayed on a V-screened TV screen.

[0009]

In order to solve the above-mentioned problems, a system for investigating a signboard advertisement effect of a TV broadcast according to the present invention is mounted on a TV camera installed at a predetermined position to detect a camera direction. A camera direction detector mounted on the TV camera, a zoom amount detector for detecting the zoom amount of the camera, and a camera direction detected by the camera direction detector at predetermined intervals for a TV image taken by the TV camera. And a data insertion means for inserting the zoom amount detected by the zoom amount detector, and a camera position signage correspondence memory for storing each signage included in the TV image when the TV camera is set to each camera direction and each zoom amount. And TV
Data extracting means for extracting a camera direction and a zoom amount from an image at a predetermined cycle; signboard reading means for reading each signboard corresponding to the camera direction and the zoom amount sequentially extracted at a predetermined cycle from a camera position signboard correspondence memory; A signboard appearance counter for counting the number of times each signboard is read by the signboard reading means as the number of appearances of each signboard in the TV image;

In the TV broadcast signboard advertisement effect research system configured as described above, the camera direction and the zoom amount of the TV camera are constantly detected. That is, in a TV camera installed at a predetermined position, if a camera direction and a zoom amount are determined, a TV image obtained by the TV camera is a fixed image except for a competitor or a spectator. Of course, if the camera direction and the zoom amount are determined, the signboard included in the TV image obtained by this TV camera is also specified.

Therefore, in the memory corresponding to the camera position signboard,
Each signboard included in the TV image when the TV camera is set to each camera direction and each zoom amount is stored.
Therefore, by measuring the camera direction and the zoom amount of the TV camera at each time, the number of appearances (appearance frequency) of the signboard in the TV image can be grasped.

[0012] In another aspect of the present invention, in the above-described system for investigating a signboard advertisement effect of a TV broadcast, the signboard reading means continues the predetermined number of times of the signboard appearance number counted by the signboard appearance frequency counter. Only when the data has been read out, a corrected appearance frequency counter is provided which counts this as a new corrected appearance frequency.

As described above, when the camera direction of the TV camera changes at a high speed, even if a signboard appears on the TV screen, if the signboard disappears at the next moment, the viewer of the TV sets the contents of the signboard. I can't figure out. Therefore, in the present invention, only when the signboard continuously appears (broadcasts) for a predetermined number of cycles (predetermined time), it is determined that the signboard has been broadcast on the TV screen. With such a configuration, the effect of the signboard advertisement that is closer to the actual one can be grasped.

The data insertion processing section 7 adds the input camera number A, camera orientation α,
β and the zoom amount Z are inserted at predetermined intervals as insertion data (A, α, β, Z). A specific method of inserting the insertion data (A, α, β, Z) into the TV image signal a will be described with reference to the schematic diagram of the TV image signal a shown in FIG.

The TV image signal a is actually a signal in which 525 scanning line signals are connected in series. For simplicity of explanation, as shown in FIG. It is assumed that the image data is composed of image data 11 which is a still image repeated in a cycle and a blanking section 12. And 1/30
The insertion data (A, α, β, Z) is written in a blanking section 12 that appears in a predetermined cycle of seconds. Therefore, 1
The image data 11, which is each still image updated at a predetermined cycle of / 30 seconds, includes the camera number A of the TV camera 1, the camera orientation α, β,
The zoom amount Z is stored as insertion data (A, α, β, Z) in the adjacent blanking section 12. In addition, the inserted data (A, α,
β, Z) are not displayed on a general TV receiver.

The TV image signal a in which the insertion data (A, α, β, Z) output from the data insertion processing section 7 is inserted in each blanking section 12 is output to the VTR 9 for replay.
At the same time, and input to the program organizing device 10.
The program organizing device 10 selects and broadcasts the optimum TV image signal a at this time among the TV image signals a output from the data insertion processing unit 7 of each TV camera 1 according to the operation of the program director. It is transmitted to the relay device 13 as a TV image for use.

The relay device 13 receives the input TV image signal a

Is transmitted to the relay device 17 on the broadcast station side via the. The TV image signal a received by the relay device 17 is recorded on the VTR 18 and transmitted to the broadcasting station 19. The broadcast station 19 broadcasts the received TV image signal “a” on an airwave from an antenna (television tower) 20. In the broadcasting station 19, it is also possible to remove the insertion data (A, α, β, Z) inserted in the blanking section 12.

TV image signal a recorded on VTR 18
Is read out asynchronously with respect to the broadcast, and is input to the data analysis device 21 that investigates the advertising effect of the signboard advertisement.

For example, the data analysis device 21 composed of a computer is configured as shown in FIG. As shown in FIG. 4, a camera that stores each sign 29 included in the TV image data 11 when each of the TV cameras 1 is set to each of the camera orientations α and β and each of the zoom amounts Z as shown in FIG. Location signboard correspondence database (memory) 24
Is provided.

More specifically, as shown in FIG. 6, a camera number A, a camera direction α, and a camera direction A which constitute the insertion data (A, α, β, Z) inserted into the blanking interval 12 of the TV image signal a. For all combinations of β and zoom amount Z, all signboards 29 attached to this baseball stadium when the TV camera 1 sets the camera orientations α, β and zoom amount Z corresponding to the combination. In each of the signboards 29, whether or not the signboard 29 appears (is included) in the image data 11 is stored. Then, it is “1” when it appears (is included), and is “0” when it does not appear (is not included).

Note that, as shown in FIG.
, The case where the signboard 29 is included in half or more is set to “1” as appearing (included). The camera directions α and β are set, for example, every 1 °, and the zoom amount Z is set, for example, every 1 mm.

In FIG. 5, the TV image signal a shown in FIG. 3 reproduced from the VTR 18 is inserted into the blanking section 12 by the data extracting section 22 at 1/30 second intervals of inserted data (A, α, β, Z) to extract the signboard reading unit 2
Send to 3. The signboard reading unit 23 searches the database 24 corresponding to the camera position signboard with the input insertion data (A, α, β, Z), and indicates the appearance corresponding to the insertion data (A, α, β, Z). Each signboard 29 (signboard number) set to "1" is read out and sent to the signboard appearance frequency counter 25.

This signboard appearance frequency counter 25 is provided for each signboard 29 set in the camera position signboard correspondence database 24.
Is counted.

The signboard appearance frequency counter 25 sends the counted appearance frequency CN of each signboard 29 to the next corrected appearance frequency counter 26. The corrected appearance counter 26 displays the corrected track maintenance appearance number CM on the display 27 and the printer 28.
Send to The display 27 and the printer 28 display and output the corrected appearance frequency CM of each input signboard 29 (signboard number) and output the same in a report.

The data analyzer 21 constructed as described above
Will be described with reference to a flowchart shown in FIG.

TV image signal a reproduced from VTR 18
Is input (S1), the data extraction unit 22 inserts the inserted data (A, α, β,...) From the blanking section 12 adjacent to the image data 11. Z) is extracted (S2). Next, the camera position signboard correspondence database 24 is searched with the extracted insertion data (A, α, β, Z), and the relevant insertion data (A,
The signboard number set to “1” indicating the appearance corresponding to α, β, Z) is read (S3).

Then, the number of appearances CN of the signboard number set to "1" which has been read this time in the signboard appearance frequency counter 25 is updated (S4).

CN = CN + 1 Further, the appearance number CN of the signboard number set to "0" which has not been read out this time in the signboard appearance number counter 25 is cleared to 0 (S5).

CN = 0 Then, it is checked whether or not there is a signboard 29 (signboard number) whose appearance number CN in the updated signboard appearance number counter 25 has reached 15 (S6). Number of appearances CN is 15
Is reached, it is determined that the relevant signboard 29 has been displayed on the TV screen of the TV receiver continuously for 0.5 second or more, and the appearance frequency CM of the relevant signboard number in the corrected appearance frequency counter 26 is updated ( S7).

CM = CM + 1 Next, the appearance number CN of the signboard number in the signboard appearance number counter 25 is cleared to 0 (S8).

In the TV broadcast signboard advertisement effect research system configured as described above, as shown in FIG.
The camera directions α and β of the camera 1 and the zoom amount Z are constantly detected by the camera direction detector 6 and the zoom amount detector 5.
Then, the data insertion processing section 7 inserts the TV camera 1 as insertion data (A, α, β, Z) together with the camera number A.
Is inserted into the TV image signal a output from the.

The signboard 29 included in each image data 11 of the TV image signal a when the TV camera 1 is set to each camera direction and each zoom amount is stored in the camera position signboard correspondence memory 24. .

Therefore, the appearance number (appearance frequency) CN of the signboard 29 in the TV image can be grasped by measuring the camera number A, the camera orientation α, β, and the zoom amount Z of the TV camera 1 at each time.

Further, the signboard 2 is provided for a predetermined time such as 0.5 seconds.
Only when the number 9 continues to appear (broadcast), the corresponding sign 29
Is broadcast on the TV screen of the TV receiver. With such a configuration, the viewer does not notice,
The signboard 29 that is instantly reflected is not counted as the appearance frequency CM.

Therefore, the installer of the signboard 29 can grasp the effect of the signboard advertisement which is closer to the actual one.
