Stored in M. By operating the mouse button (C) 27 in a state where the entire screen stored in the RAM is displayed on the TV display unit 11, as shown in FIG. A frame S surrounding the telop T displayed on the display unit 11 can be displayed. Further, when another control button and the telop determination button (E) 30 are pressed while the telop T is surrounded by the frame S, the telop T is pushed to the designated control data storage area 5a of the telop memory 5 shown in FIG. The designated control data corresponding to the selected control button is stored in the telop data storage area 5b.
Then, the telop data indicating the telop T surrounded by the frame S is stored.

That is, while the telop T is surrounded by the frame S, the "volume down button 25 + the telop determination button (E)

Next, the operation of this embodiment according to the above configuration will be described with reference to the flowchart shown in FIG. That is, the microcomputer 4 operates according to the flowchart shown in FIG. 6 based on the internal program, and determines whether or not the monitor (TV display unit 11) is turned on (step S1). If the monitor is in the ON state, the image data based on the received video signal is displayed on the TV display unit 11 (step S2), and the sound based on the received audio signal is emitted from the speaker 9. Therefore, when the monitor is turned on, the TV broadcast video of the broadcast station selected in advance by operating the channel button 18 is displayed on the TV display unit 11, and the speaker 9 emits the sound of the TV broadcast. Can be

Next, it is determined whether or not the image memory button (D) 29 has been pressed (step S3). If it has been pressed, the entire screen (one screen) displayed on the TV display unit 11 at that time is determined. Is stored in the RAM (step S4). Therefore, when the screen including each telop illustrated in FIGS. 3A to 3D is displayed on the TV display unit 11, by pressing the image memory button (D) 29, the entire screen including each telop is displayed. Stored in RAM. This R
The memory image stored in the AM is displayed on the TV display unit 11 (step S5). Therefore, this step S
By the process of 5, the video display of the TV broadcast is temporarily interrupted, and a still image composed of the entire screen at the time when the image memory button (D) 29 is pressed is displayed on the TV display unit 11.

Next, a telop range selection operation process is executed (step S6). This process is performed in response to the operation of the mouse button (C) 27 as described above with reference to FIG.
This is a process of causing the TV display unit 11 to display a frame S surrounding the telop T displayed on the TV display unit 11. That is, when the mouse button (C) 27 is operated in a state where the still image including the full screen is displayed on the TV display unit 11, a frame S is displayed on the TV display unit 11 in accordance with the operation. Accordingly, the user can select and specify only a desired telop T from the memory image displayed on the TV display unit 11 by removing unnecessary background.

When the telop range selection operation processing surrounding the desired telop T by this frame S is completed, it is determined whether or not the telop determination button (E) 30 has been pressed together with other control buttons (step S7). Then, when the telop determination button (E) 30 and another control button are pressed, the telop data indicating the telop T surrounded by the frame S is stored in the telop data storage area 5b of the telop memory 5 and Then, the designated control data corresponding to the pressed control button is stored in the designated control data storage area 5a (step S8).

As described above, when the "volume down button 25 + the telop determination button (E) 30" is simultaneously pressed in the state where the telop T is surrounded by the frame S as described above, the designation control is performed. "Volume down" is stored in the data storage area 5a, and the telop data of "telop T" is stored in the corresponding telop data storage area 5b. In addition, by repeatedly executing the processing of steps S1 to S8 in response to the user's button operation, the designated control data storage area 5a and the telop data storage area 5b of the telop memory 5, for example, "volume up" (Return volume) "or" Start recording "
Alternatively, the TV program theme screen telop of FIG. 3 (1) is stored corresponding to “power on”, and the CM of FIG. 3 (2) corresponding to “decrease volume” or “pause / cancel recording”.
The telop appearing on the verge or the telop appearing in the CM shown in FIG. 3 (3) is stored, and the CM shown in FIG. 3 (4) ends in response to “turn up the volume (return the volume)” or “start recording”. The telop appearing at the time of resumption is stored.

When the determination in step S7 is made,
No other control button is pressed and telop decision button (D) 3
If only 9 is pressed, it is determined to be invalid, and the process waits without proceeding to the next step S8 until another control button is pressed.

On the other hand, if the result of determination in step S1 is that the monitor (TV display unit 11) is off, and if the result of determination in step S3 is that the image memory button (D) 29 has not been pressed, step S9 Is determined. That is, by comparing the telop of the TV image based on the video signal input from the chroma 15 to the microcomputer 4 with each telop data previously stored in the telop data storage area 5b of the telop memory 5, the two are substantially matched. It is determined whether or not it has been performed. The processing in step S9 includes processing example 1 shown in FIG. 7, processing example 1 'shown in FIG.
The processing is performed by at least one of the processing examples 2 shown in FIG. 10 or a combination thereof.

In processing example 1, each character of the telop data stored in the telop data storage area 5b of the telop memory 5 is captured as a combination of matrix data by chroma key processing. That is, when the telop data of “Summer! Date Story” including the character of “de” in FIG. 7A is stored in the telop data storage area 5b, the character of “de” is X = 1 to 9, In the matrix of Y = 1 to 9, (X4, Y9) (X5, Y
8) (X5, Y7) (X5, Y6) (X6, Y6)... (X8, Y3) (X9, Y3) (X9, Y2). It corresponds to the character of the form shown in b) (however, the combination is performed not for the character alone but for the entire telop).

Then, the TV image being received processed in the microcomputer 4 is accessed at a fixed period (for example, once per second), and a combination of matrices substantially coincident with a combination of any of the stored telop matrices. Is searched for in the TV image being received. At this time, if only a telop search made up of the same matrix combination as the telop matrix stored in the memory is performed, when a different distortion or telop shift occurs in the TV image from that in the memory, a telop having a matching telop can be obtained. Cannot be detected.

Therefore, as shown in FIG. 2C, the same number (A for X and a for Y) is added to and subtracted from each of the X values and Y values of the matrix combination at the time of retrieval. , (X4 +
A, Y9 + a) (X5 + A, Y8 + a) (X5 + A, Y6 + a) (X5 + A, Y6 + a) (X6 + A, Y6 +
As a), a search is made for a telop composed of the adjusted matrix combinations. At this time, A and a are set within ± 3 (FIG. (C) when A = −1, a = −2), and within this range, the same as a matrix combination in which the values of X and Y are adjusted. If the telop of the matrix combination is present in the TV image, it is determined that the telops substantially match. Further, in processing example 1 ', as shown in FIG. 8, different numbers are added to and subtracted from each of the values of the combination of matrix data and each of the values of Y obtained by the chroma key processing of processing example 1 described above. X4 + A, Y9 + a) (X5 + B, Y8 + b) (X
A telop composed of the adjusted matrix combinations is searched for as 5 + C, Y6 + c) (X5 + D, Y6 + d) (X6 + E, Y6 + e). At this time, A, B, C ..., a, b, c ...
Is performed within ± 3, and if a telop of the same matrix combination as the matrix combination in which the X and Y values are adjusted within this range is present in the TV image, it is determined that the telops substantially match. . Therefore, in the processing example 1 ', even if the TV image has a character blur different from that in the memory, a telop having a coincidence is properly detected.

Further, in processing example 2, each character of the telop data stored in the telop data storage area 5b of the telop memory 5 is subjected to the outline detection processing, and the telop subjected to the outline detection processing is set to the same luminance single-color portion. It is captured by a combination of horizontal lines Y as levels. That is,
When the telop data of “Natsu! Date Story” including the character of “de” in FIG. 9A is stored in the telop data storage area 5b, the character of “de” is subjected to the contour detection processing (FIG. 9A). It can consist of the contour shown in b). Also, the outline character shown in FIG. 7B can be represented by a combination of signal levels as shown in FIG. 8C, when it is captured by a combination of lines Y having the same luminance single color portion at a high level.

The TV image being received, which has been processed in the microcomputer 4, is accessed at regular intervals to perform the same contour detection processing, and the combination of horizontal lines Y having the same luminance single-color portion as a high level is used. A telop is taken, and a search is made to determine whether or not the combination of the horizontal lines Y substantially matches the combination of the horizontal lines Y of any of the stored telops. At this time, if only a telop composed of the same combination of the horizontal lines Y as the combination of the stored horizontal lines Y is searched,
When a horizontal enlargement different from that in the memory occurs in the TV image, a consistent telop cannot be detected. Therefore, as shown in FIG. 10, a -3 msec.
An error of +3 msec is sequentially set, and a search for a telop composed of a combination of horizontal lines in which the error is sequentially set is performed. If a telop composed of the same horizontal line combination as the error-set horizontal line combination is present in the TV image, it is determined that the telops substantially match.

In this manner, the telop data stored in the telop memory 5 in the TV image substantially matches the telop shown in the telop memory 5 by one of the processing 1, the processing 1 ', and the processing 2 or a combination thereof. If it is detected that there is a telop, a process corresponding to the designated control data stored in the telop memory 5 corresponding to the matched telop is executed (step S1).
0).

That is, the (1) TV program theme screen telop shown in FIG. 3 is stored in memory corresponding to the designated control data "increase the volume (return the volume)".
The telop that almost matches the TV program theme screen telop is TV
When the sound is reproduced in the image, the sound adjustment circuit 7 is controlled via the sound demodulation circuit 31 in accordance with the designated control data “increase the sound volume (return the sound volume)”, and the sound volume from the speaker 9 is increased. Further, (2) the telop appearing immediately before the CM is stored in correspondence with the designated control data "decrease the volume", and the telop substantially matching the (2) telop appearing immediately before the CM is reproduced in the TV image. In such a case, the sound adjustment circuit 7 is controlled in accordance with the designated control data “decrease the volume” to lower the volume from the speaker 9. Furthermore, (4) C
The telop appearing at the end of M and resuming the program is stored in correspondence with the designated control data "increase the volume (return the volume)", and the (4) telop appearing at the end of the CM and resuming the program is in the TV image. When the sound is reproduced, the sound adjustment circuit 7 is controlled in accordance with the designated control data “increase the volume (return the volume)”, and the volume from the speaker 9 is increased. Therefore, every time a commercial starts, the volume is lowered,
A complicated operation of raising (returning) the volume each time is completed becomes unnecessary, and the TV viewing can be performed at a substantially constant comfortable volume without such a complicated operation.

The (1) TV program theme screen telop shown in FIG. 3 is stored in correspondence with the designated control data "recording start", and the (1) TV program theme screen telop substantially coincides with the telop. When reproduced in the TV image, the recording unit 10 responds to the designated control data “recording start”.
To start recording. In addition, (2) the telop appearing immediately before the CM is stored in correspondence with the designated control data "pause of recording", and the telop substantially matching the (2) telop appearing immediately before the CM is reproduced in the TV image. In this case, the recording unit 10 is controlled in accordance with the designated control data “recording pause” to stop recording. Further, (4) the telop that is output when the CM ends and the program is restarted is stored in memory corresponding to the designated control data "recording start".
When the telop appearing at the end of M and resuming the program is reproduced in the TV image, the recording unit 10 is controlled in accordance with the designated control data “recording start”, and recording is resumed. This allows
It becomes possible to record a program in which a CM has been cut, and to record the program from the beginning to the end even when the broadcast time of the program is changed.

The (1) TV program theme screen telop shown in FIG. 3 is stored in correspondence with the designated control data "power ON", and the (1) TV program theme screen telop substantially coincides with the TV program theme screen telop. When reproduced in the TV image, the power of the TV display unit 11 is controlled in accordance with the designated control data “power on”, and the TV display unit 11 is turned on. As a result, the TV program having the TV program subject screen telop is displayed on the TV display unit 11. Also,
Although not shown in FIG. 3, a program end telop such as "continue" or "end" displayed when the program ends is stored in correspondence with the designated control data "power off". When a substantially matching telop is reproduced in the TV image, the power of the TV display unit 11 or the power of the VTR-integrated TV is turned off in accordance with the designated control data “power off”. Therefore, the power can be turned on automatically at the start of a desired program to display the program, and the power can be turned off automatically at the end of the program.

When the reproduction is performed by the reproduction section 14 of the VTR block 3, the reproduced video signal is supplied to the microcomputer 4 via the chroma circuit 15, and the microcomputer 4 outputs the video reproduced image. And the telop stored in the telop memory 5 is detected, and the same control as described above is performed. As a result, when the TV program including the CM is recorded as it is in the recording unit 10 and the TV program including the CM is reproduced, it is possible to reduce the volume of the CM program.

Further, the emergency broadcast telop is stored in correspondence with the designated control data "power on", and if a telop substantially matching the emergency broadcast telop is reproduced in the TV image, the designated control data The power of the TV display unit 11 is controlled in accordance with “power on”, and the TV display unit 11 is turned on. As a result, the emergency broadcast can be reliably displayed, and the notification effect of the emergency broadcast can be enhanced.

Note that, as described above, the microcomputer 4
5 and fetches a video signal based on the video signal.
Since the determination in step S9 is performed by comparing the V image data with the telop data in the telop memory 5, the TV
Even in a state where the display unit 11 is off, the determination in step S9 can be performed without any trouble. However, in order for this determination to be performed, the TV tuner 2
In addition, since the microcomputer 4 must operate, when the power is turned on from off, even if the other parts are off, both need to be kept on.
However, when the power is turned off from on, the entire TV tuner 2 and the microcomputer 4 may be turned off.

Further, in the embodiment, the telop memory 5 is provided, and the data stored in the telop memory 5 is taken in from the TV image by operating the button.
A telop may be read from a sheet on which a telop created in advance is printed by a scanner and stored. Alternatively, fixed telop data may be stored in a memory, and the consistency with the fixed telop data may be detected. In this case, if the telop data and the like are stored for each program or for each TV station in each of the plurality of removable memories, and the plurality of memories are selectively mounted to detect the coincidence, The volume control and the like can be performed more accurately without the operation of storing the telop. In addition, the target for which the storage and the matching are detected is not limited to the telop, but may be another image. The processing for detecting the matching is not limited to the processing 1, the processing 1 ', and the processing 2 described above. May be used.

FIG. 11 shows another embodiment of the present invention. A storage device 32 is further connected to the microcomputer 4, and the storage device 32 has the same configuration as that of the above-described embodiment. Storage medium 3 in which a program is stored in advance

As described above, according to the present invention, a preset image and a television image are compared, and when they substantially match, a predetermined control is performed. The predetermined control can be performed perfectly without complicated operations. Further, since the setting image is selected and set in advance from television images, even when the images are various, control can be perfectly performed without any trouble. When desired control data can be set and the set image substantially matches the television image, by executing control based on the control data, there are various cases where the control to be executed is various. Can also respond. In addition, by storing a plurality of set control data corresponding to different setting images and executing control based on the control data corresponding to the setting image substantially matching the television image, various controls can be appropriately performed. Can be done at any time.

Further, since the control data is for increasing or decreasing the volume of the television sound, the volume can be automatically and appropriately increased and decreased at the time of CM and at the end of the TV broadcast. In addition, since the control data is for turning on and off the display of a television image, it is possible to perform on / off control of a TV receiver in accordance with a TV program, thereby suppressing power consumption. In addition, it is possible to surely view a desired program. Further, since the control data controls the recording operation of the recording means for recording television images, it is possible to completely record a desired program without being affected by a change in program broadcast time. Becomes Further, since the setting image is a telop in a television image, it is possible to easily determine the approximate matching between the setting image and the television image, and to accurately determine the approximate matching. .
