DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information presenting apparatus such as a television receiver, and more particularly, to an information presenting apparatus for presenting information about another viewing channel to a sub-perception.

[0002]

2. Description of the Related Art As a conventional information presenting apparatus of this type, there is known an information presenting apparatus which divides a display screen of a display into tiles and simultaneously displays a plurality of viewing channel images in each divided area.

[0003] Japanese Utility Model Publication No. 1-80221 discloses that, when trying to test a channel other than the channel currently being viewed, the receiving channel is automatically and sequentially changed by operating a channel round feed switch. It describes a channel selection device of a television receiver that changes every predetermined time, for example, every three seconds, and can sequentially test all channels, for example, 12 channels.

On the other hand, Japanese Patent Application Laid-Open No. Hei 5-244530 discloses that an inserted image stored in an IC card, a ROM, or the like is inserted into an original video signal being viewed at inconspicuous timing such as when a scene changes. Accordingly, there has been proposed a display device that induces and promotes a physiological or psychological demand or state of a viewer using a subliminal effect.

[0005]

However, in the case of spatially dividing the display screen described above, there is a problem that each viewing channel image displayed in the divided area becomes small, and it is difficult to visually recognize the channel image.

Further, in the case of Japanese Utility Model Publication No. 1-80221, all channels are sequentially displayed every three seconds, so that the user is currently visually recognizing for 3 × (the number of all channels−1) seconds. There was a problem that the main viewing channel image could not be viewed.

[0007] Furthermore, in Japanese Patent Application Laid-Open No. 5-244530, an IC storing an inserted image for the purpose of a subliminal effect (physiological and psychological demands of a viewer, an effect to induce a state) is stored. Not only must a storage medium such as a card or a ROM be prepared, but depending on the contents of the inserted image, there is a problem that the physiological and psychological state of the viewer may be adversely affected.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has a simple configuration to set another viewing channel image below a threshold so as not to disturb the currently viewed main viewing channel image. It is an object of the present invention to provide an information presentation device that can be provided at a level of perception (which does not change a psychological state).

[0009]

An information presentation apparatus according to the first aspect of the present invention comprises a main video receiving unit for receiving a main viewing channel video, a sub video receiving unit for receiving another viewing channel video, A synchronizing signal extracting means for extracting a synchronizing signal from the main viewing channel image received by the main image receiving means; and a synchronizing signal extracted by the synchronizing signal extracting means. And video switching means for switching and outputting the other viewing channel video, and a display for displaying the video switched and output by the video switching means.

[0010] With this, it is possible to switch and display the main viewing channel image with respect to the main viewing channel image only during a period in which the other viewing channel image is kept below the threshold with a simple configuration. It is possible to know whether or not an image of interest is being received on the channel.

That is, the sub-threshold perception here is to perceive an external stimulus under consciousness without awareness.
As a result, it does not affect the psychological state of the perceiver, but leaves a trace on the unconscious consciousness. Is different from

According to a second aspect of the present invention, in the information presenting apparatus according to the first aspect,
An image synthesizing unit for synthesizing a channel number with the other viewing channel image received by the sub-image receiving unit is provided.

[0014] With this, it is possible to present a composite of the other viewing channel video and the channel number only for the period of subliminal perception, so that it is possible to determine on which channel the presented video of interest is being broadcast. It becomes possible to know.

According to a third aspect of the present invention, in the information presenting apparatus according to the second aspect,
Recognition means for recognizing the non-important video portion of the other viewing channel video received by the sub-video receiving means is provided, and the image synthesizing means synthesizes a channel number with the non-important video portion recognized by the recognition means. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the information presenting apparatus of the present invention will be described with reference to FIG.
And FIG. Here, FIG. 1 is a block diagram showing a schematic configuration of the information presenting apparatus of the present embodiment, FIG. 2 is a timing chart showing an operation of generating an other viewing channel video in the information presenting apparatus of the present embodiment, and FIG. FIG. 4 is a timing chart showing the switching operation between the main viewing channel video and the other viewing channel video in the information presentation device of FIG.
FIG. 5 is an explanatory diagram illustrating a generation operation of a display video in the information presentation device of the present embodiment.

The television receiver according to the present embodiment has the configuration shown in FIG.
As shown in FIG. 1, a main video receiving unit 1 for receiving a main viewing channel video currently being viewed by a user, a synchronizing signal extracting unit 2 for extracting a synchronizing signal from a video signal received by the main video receiving unit 1, A frequency dividing circuit 3 for dividing the synchronization signal extracted by the synchronization signal extracting section 2 to generate a sub-channel switching signal having a predetermined period (for example, 5 seconds).

Also, based on the sub-channel switching signal from the frequency dividing circuit 3, the receiving channel is sequentially switched to receive a video of another viewing channel, and a video signal received by the sub-video receiving unit 4. In contrast, by extracting edges, a channel number is generated based on the empty space extraction unit 5 that detects a relatively low-density part and the frequency band information received by the sub-video reception unit 4. A channel number generation unit 6;
And an image synthesizing section 7 for superimposing and synthesizing the corresponding channel number on the empty space of the video signal received in the step (a).

Further, based on the synchronizing signal extracted by the synchronizing signal extracting section 2 and the sub-channel switching signal generated by the frequency dividing circuit 3, a predetermined period (for example, 1/100 to 1/100) is obtained.
(30 seconds) main / sub video switching signal generating section 8 for generating a main / sub video switching signal, and a main video based on the main / sub video switching signal generated by the main / sub video switching signal generating section 8 There is provided a main / sub-video switching unit 9 for switching between a main viewing channel video received by the receiving unit 1 and another viewing channel video whose channel number has been synthesized by the image synthesizing unit 7 and outputting to the display 10. .

In the television receiver configured as described above, the main video receiving unit 1 receives the main viewing channel video by the user's selection, and the main / sub video switching unit 9
Through the display 10. on the other hand,
As shown in FIG. 2, the sub-video receiving unit 4 sequentially switches the receiving frequency band based on a 5-second cycle sub-channel switching signal generated from the synchronization signal of the main viewing channel video, so that the sub-video receiving unit 4 is switched in units of 5 seconds. Other viewing channel image A ~
G is continuously received.

The other viewing channel images A to G received by the sub-image receiving unit 4 are compared with threshold values stored in an edge detection threshold value memory of the free space extracting unit 5, and the edge strength is determined by the threshold value. In this case, a pattern is set to “1”, and when the strength of the edge is less than the threshold value, to “0”.
From the distribution of the pattern, a low-density part (an unimportant part) in each of the other viewing channel images A to G is detected and output to the image synthesizing unit 7.

The channel number generator 6 determines the channel number received by the sub-video receiver 4 by referring to the table from the frequency band information transmitted from the sub-video receiver 4, and determines the number of the channel number. The image is output to the image synthesizing unit 7. The image synthesizing unit 7 synthesizes a numerical image of a channel number from the channel number generating unit 6 with a low-density part in each of the other viewing channel images A to G extracted by the free space extracting unit 5, and forms a main / sub image. Output to the switching unit 9.

Further, as shown in FIG. 3, the main / sub-video switching signal generating section 8 converts the synchronizing signal extracted by the synchronizing signal extracting section 2 and the sub-channel switching signal generated by the frequency dividing circuit 3. , A main / sub video switching signal having a period of 1/100 to 1/30 seconds is generated, and the switching of the main / sub video switching unit 9 is controlled in accordance with the main / sub video switching signal.

That is, the main / sub video switching unit 9
For the period of 1/100 to 1/30 seconds, the main viewing channel image is switched to the other viewing channel images A to G and output to the display 10. Therefore, the viewer can view the main viewing channel image on the display 10 while
Other viewing channel images A to G presented only by sub-threshold perception
It becomes possible to know the contents of.

Since the other-viewing channel images A to G are presented only during the period in which the sub-threshold is perceived, a physiological desire, such as a so-called subliminal effect, that the user wants to view the other-viewing channel images is induced. There is no effect, and only a trace of the contents of the other viewing channel images A to G is left in the viewer's unconsciousness.

As described above, in this embodiment, the other viewing channel image shown in FIG.
An edge shown in FIG. 4B is detected, and an empty space as shown in FIG. 4C is extracted. Further, the numeric image of the channel number shown in FIG. 4D is superimposed on the free space of the other viewing channel image to create a composite image as shown in FIG. It outputs a display image that is inserted into the channel video only for a period of time during which it is kept below the threshold.

Thus, it is possible to know whether or not an interesting video is being received on another viewing channel without interrupting the viewing of the main viewing channel video.
In addition, since the channel number is combined with the non-important video part that does not disturb other viewing channel video and presented,
Without overlooking important parts of other viewing channel images,
It becomes possible to know which channel is being broadcast.

In the above embodiment, the sub-channel switching signal is described as having a period of 5 seconds. However, the present invention is not limited to this. By changing the setting of the frequency dividing circuit 3 according to the presentation time and the content of the presentation. , A sub-channel switching signal having an arbitrary period can be generated.

The other viewing channel image received by the sub-image receiving unit 4 does not need to be switched to another channel image at a certain fixed period like B, C, D, E. , B, C, C, etc., the same channel image may be output a plurality of times.

Further, since the main / sub video switching signal is generated by using the synchronization signal of the main viewing channel video,
For example, if the method is to display 30 frames per second, 1/3
If the system displays 60 frames per second for 0 seconds, 1 /
It can be set arbitrarily in accordance with the display method within a range of sub-threshold perception, such as 30 to 1/60 seconds. The main / sub video switching signal is generated once for each channel of the other viewing channel video using the sub channel switching signal.

[0032]

The information presenting apparatus according to the first aspect of the present invention has the above-described configuration. Therefore, with the simple configuration, the main viewing channel image can be used to provide the other viewing channel image to the sub-perception. Since it is possible to switch and display only during the holding period, it is possible to know whether or not an interesting video is being received on another viewing channel without disturbing the main viewing channel video.

[0033] The information presenting apparatus according to the second aspect of the present invention can present a composite of the other viewing channel image and the channel number only for the period of subliminal perception. It is possible to know on which channel a certain video is being broadcast.

The information presenting apparatus according to the third aspect of the present invention can present an image obtained by combining a channel number with an insignificant image portion which does not disturb other viewing channel images only for a period of time during which the sub-perception is maintained. Therefore, it is possible to prevent an important part of the presented video from being overlooked.
