TV moving object enlarged display device {MOVING OBJECT ENLARGING APPARATUS OF TELEVISION}

The present invention relates to an enlarged display device for moving objects of a television. More specifically, when a sports broadcast relay broadcasted on a television is watched, a specified moving object is enlarged on a CRT screen when a moving object such as a golf ball or a baseball is designated. A moving object magnification display apparatus of a television for displaying in a normal state.

In general, in order to deliver a broadcast program organized by a broadcasting station to a viewer, the video signal and the audio signal captured by the video camera are modulated and transmitted over the air or transmitted to a receiving television through a video / audio cable.

In other words, when a golfer drives a golf ball during the broadcast of a golf game, the video camera tracks the golf ball. However, since the golf ball is not only small but also has a white color, the viewer may not be able to see the golf ball. Tracking is quite difficult. In addition, since the color of a baseball is generally white during the broadcast of a baseball game, it is difficult to visually track the whereabouts of the baseball when the brightness of the background image is weak. It is very likely to be.

Digital to analog conversion and output to the video processor 18 the image data output to the moving object is enlarged-portion shows the analog conversion.

Next, the operation of the moving object enlarged display device of the television having the above-described configuration will be described in detail with reference to FIGS. 2A and 2B.

First, when a normal channel number is performed by the remote controller 10, the control unit 12 reads the tuning data VT corresponding to the channel number from the tuning data memory (not shown) to the tuner 14. As a result, the tuner 14 tunes a channel corresponding to the tuning data VT and applies the video signal component of the broadcast program to the video IF processing unit 16. Accordingly, the video IF processing unit 16 converts the video signal component applied from the tuner 14 into a predetermined video IF signal and applies the video IF signal to the video processor 18. 18) reproduces the video IF signal as an R / G / B color signal and outputs it to the CRT apparatus 20. FIG.

In the case where the video signal of the channel reproduced by the above process is, for example, sports relay broadcasting, particularly in the case of a golf game or a baseball game, the viewer operates the mode setting button 10a of the remote controller 10 to enlarge the processing mode of the moving object. Is set, the control unit 12 activates the analog-to-digital conversion unit 22 and the video IF signal reproduced by the video processor 18 is applied to the analog-digital conversion unit 22 side. Done. Then, the analog-to-digital converter 22 digitally converts the image IF data in horizontal line units and sequentially stores and reads the image IF data in the field memory 24, and provides one field amount in the field memory 24. The image data read out in a state where the image data is stored is applied to the moving object tracking unit 26 to track the moving object by detecting a white level for a golf ball in a golf game or a baseball ball in a baseball game, for example. The tracking result of the moving object is applied to the control unit 12. Therefore, the control unit 12 controls the cursor display control unit 28 so that the cursor points to a golf ball (or a baseball ball in the case of a baseball game) as the moving object based on the moving object tracking result.

That is, when the golf ball 20b as the moving object is located in the background image 20a as the image output from the field memory 24 is illustrated in FIG. 2A, the moving object tracking unit 26 may perform the field memory 24. Detecting the white level of the image data sequentially output at 24 in horizontal line units to generate a tracking result for the circular golf ball 20b which is a white color component and thus the tracking result of the golf ball 20b (that is, Position on a horizontal scanning line) to the control unit 12, whereby the control unit 12 controls the cursor display control unit 28 to point to the golf ball 20b shown in Fig. 2A. A cursor control signal for displaying the cursor 20c is generated to be displayed on the CRT apparatus 20 through the video processor 18.

In the state where the display of the cursor 20c is performed, the viewer inputs by operating the confirmation button 10c of the remote controller 10 when the cursor 20c is judged to correctly point to the golf ball 20b as the moving object. When the confirmation signal by the confirmation button 10c of the remote controller 10 is not input, the control unit 12 moves based on the white level detection result applied from the moving object tracking unit 26. The position of the golf ball as an object is reconfirmed, and the cursor display control unit 28 is controlled to correct the position of the cursor with respect to the position of the reconfirmed moving object, and the golf ball 20b is corrected by such a position correction method. The position determination of is performed.

Therefore, as the cursor 20c of the golf ball 20b as the moving object in the background screen 20a displayed on the CRT apparatus 20 is correctly pointed, the confirmation button 10c of the remote controller 10 is applied. When the confirmation signal is inputted, the control unit 12 waits for the expansion ratio adjustment signal by the expansion ratio adjustment button 10b of the remote controller 10, and while the standby state lasts for a predetermined time, the expansion ratio adjustment button ( If the adjustment ratio of the expansion ratio is input from 10b), the expansion ratio of the moving object is controlled based on the expansion ratio, while the adjustment ratio of the expansion ratio is input from the expansion ratio adjustment button 10b even while the standby state lasts for a predetermined time. In this case, the expansion ratio for the golf ball 20c as the moving object is controlled based on the expansion ratio of 2 times that is basically selected in the moving object expansion mode. do.

That is, when the expansion ratio is set by the expansion ratio adjustment button 10b of the remote controller 10, the controller 12 generates an expansion ratio control signal CNT corresponding to the expansion ratio to the moving object expansion unit 30. If the expansion ratio is not set from the expansion ratio adjustment button 10b of the remote controller 10, an expansion ratio control signal ENT is generated by a basic expansion ratio (i.e., 2 times) and the moving object expansion unit 30 is applied. The moving object expansion unit 30 is a golf ball as a moving object among the image data applied by the moving object tracking unit 26 by an expansion ratio control signal CNT applied by the control unit 12. The expansion processing for 20b, that is, the expansion processing by the redundant pixel data storage and output method for the data of the golf ball 20b, and the luminance (contrast) is forcibly applied to the background image of the expanded moving object. level The image data processed in the state in which the moving object is expanded in the moving object expansion unit 30 is converted into an analog signal through the digital-to-analog converter 32 to convert the video data into the video processor 18. Is reproduced by the R / G / B color signal and outputted to the CRT apparatus 20 for display.

Accordingly, the image displayed on the CRT apparatus 20 by being processed under the control of the controller 12 is displayed in the background screen 20a 'in which the luminance (contrast) level is reduced as illustrated in FIG. 2B. The ball 20b 'is displayed in an expanded state so that the enlarged state of the moving object can be displayed while the brightness difference between the background screen 20a' and the moving object is increased.

Here, since the golf ball or the baseball ball as the moving object displayed on the CRT apparatus 20 is focused by the video camera, the moving object tracking unit 26 discriminates the field level image data by detecting the white level. The position change tracking of the data on the circular moving object having a high white level becomes possible, and the enlargement processing for the moving object under the control of the control unit 12 by the tracking result of the moving object is performed even when the image frame is changed. Can be run satisfactorily.

On the other hand, although the golf ball or baseball ball is mentioned as the moving object to be expanded in the present invention, the present invention is not limited to such an application example, for example, it can be appropriately applied to sports games of the whole ball game. .

As described above, according to the moving object enlarged display apparatus for television according to the present invention, the enlargement processing function is set for a golf ball or a baseball ball designated as a moving object during sports broadcast broadcasting, so that the enlarged display of only the moving object is possible. As a result, the viewing effect of the sports game can be further improved.
