Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device in which a television receiver or the like has a function of appealing to a viewer's deep psychology.

[0002]

2. Description of the Related Art FIG. 9 is a block diagram of a conventional display device shown in a color television textbook (edited by Japan Broadcasting Corporation). In the figure, 1 is a signal processing circuit for receiving a video signal to be displayed and processing it in a form suitable for the display device 3, and 2 is an addressing circuit for receiving the synchronization signal and allocating the video signal to an arbitrary location of the display device 3. Yes, C
It corresponds to the deflection circuit in the RT display. Reference numeral 4 is a viewer who perceives light from the display device 3.

Next, the operation will be described. Whatever the signal source, such as TV reception signal, VTR reproduction signal, etc.,
At the display stage, as shown in FIG. 9, a video signal to be displayed and a synchronization signal designating a place where the video signal should be displayed are supplied.

The signal processing circuit 1 processes the video signal into a form suitable for the display device 3 and supplies it. On the other hand, the addressing circuit 2 processes the synchronization signal so as to cause a predetermined location of the display device 3 to emit light in accordance with the video signal.
Supply to the display device 3.

The light emitted from the display device 3 forms an image on the retina through the eyes of the viewer 4 and, finally, the information is perceived by the brain.

[0006]

The conventional display system is as described above, and the signal is reproduced in order to faithfully reproduce the original image on the display device even though the final image is perceived by the brain. Since the processing circuit 1 has been devised in various ways, it was not always effective. Further, since various information is input to the brain, the impression of the perceived image greatly depends on the psychological and physiological state of the viewer.

Further, there is a problem in that, while watching the program, due to the entertainment property, the user cannot keep an eye on the display and other work is stagnant.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a display capable of releasing an unpleasant physiological and psychological state and realizing a perceptually refreshing image. To do.

[0009]

The display device according to the present invention is such that an image generated according to the purpose can be inserted intermittently and the inserted image can be fixed and confirmed.

The above-mentioned inserted image is subjected to weighted addition with the original image, matching the APL value (average image level) with the original image, and the insertion timing is performed at the time of a scene change or disorder.

[0011]

The intermittent insertion of the generated image in the present invention utilizes the so-called subliminal effect, which induces / promotes the physiological demand and psychological effect of the viewer and provides the optimum viewing environment.

Further, the method of processing the insertion image and the insertion timing greatly improves the image quality deterioration such as the flicker of the original image due to the insertion of the insertion image.

[0013]

EXAMPLES Example 1. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 4 is a data storage device in which an inserted original image according to the purpose is recorded, such as an IC card or an R.
It is composed of OM or the like and has a structure that can be easily exchanged with other image data.

Reference numeral 5 is a speed for supplying a read control signal to the data storage device 4 from a synchronizing signal synchronized with the video signal, and adjusting the data read from the data storage device 4 to the video signal rate, if necessary. It has a conversion function and a D / A conversion function, and the output signal is supplied to the signal switching circuit 6.

The signal switching circuit 6 appropriately switches the video signal and the generated signal (inserted original image) and supplies it to the signal processing circuit 1.

The switching signal of the signal switching circuit 6 is supplied from the switching control circuit 7 and obtained by dividing the synchronizing signal. The configuration other than the above is the same as that of the conventional example shown in FIG.

Next, the operation of FIG. 1 will be described. Depending on the purpose, the inserted original image obtained from the data storage device is intermittently inserted into the original video signal through the signal switching circuit 6 to an unnoticeable degree.

The above-mentioned insertion timing is switched and controlled by the switching control circuit 7 in a regular cycle such as 1 frame cycle, m field cycle, n line cycle and the like.

It has been found that such unconscious image insertion as described above induces / promotes the physiological demands and psychological effects of the viewer depending on the contents of the inserted image, and is called a subliminal effect. There is. Hereinafter, this effect will be briefly described.

The subliminal effect was initially found and announced by J. Vikelli and Precon Process and Equipment Co. in 1957 in the United States as an initial advertising effect. In the above experiment, the CM is flashed every 5 seconds on the screen where the program is in progress in 1/3000 second to 1/20 second, and the viewer cannot see or be aware of it. However, as a result, it was reported that sales of popcorn and soft drinks increased by 50% and 30%, respectively. Although the physical mechanism of the above experimental result has not been clarified, the image to be inserted instantaneously is
It has an effect of appealing to the subconscious without going up to consciousness, and it is thought that this induces emotional, instinctual, or physiological demands of the human body. The use of the above means for public notice was banned by the US Federal Trade Commission from an ethical point of view, but at the present time as the digitalization and high sophistication of the circuit proceeded, By positively and expansively utilizing this effect, various merits can be obtained even in a general household.

First, by utilizing the above effects and applying it to a display such as a home-use television receiver, the mood is stabilized and refreshed, and the image can be enjoyed in an optimal psychological or physiological state. Not only can you expect a sense of quality improvement, but it can also be used as a psychotherapy machine. In addition, by changing the original insertion image according to the application by changing the IC card, ROM, etc., it is possible to induce physiological effects such as hunger, thirst, urination, defecation, etc. It helps to improve health by reducing the amount. Further, by inducing sleep, it is useful for preventing children from watching too much TV late at night.

As the inserted original image, various images are conceivable depending on the application, such as a temperature sensation and a feeling of comfort due to color, a sense of stability and tension due to the image spectrum, and induction of physiological development depending on the image content.

Example 2. Further, in the above-described embodiment, the original image to be inserted is configured to be inserted by switching the switch as it is, but since the problem that the inserted image is conspicuous occurs,
Figure 2 shows the improvements.

In the figure, the insertion original image from the reading circuit 5 is given a predetermined weight with the video signal, added by the weighted addition circuit 8, and the addition signal is supplied to the signal switching circuit 6 as an insertion image. Other than the above, the configuration is the same as that of the first embodiment.

According to the present embodiment, while the same effect as that of the first embodiment is obtained, the original video signal component is added even at the time of inserting the generated image, so that the discomfort at the time of insertion can be reduced.

Example 3. Regarding the problem that the inserted image is conspicuous in the first embodiment, the configuration shown in FIG. 3 has an improving effect. In FIG. 3, a circuit 9 for detecting the APL of the video signal is provided, and based on this result, the inserted original image output of the read circuit 5 is output by the APL control circuit 10 to the AP
By controlling L, the video signal and the APL of the inserted image
The values are matched and supplied to the signal switching circuit 6 as an inserted image.

The video signal is supplied to the signal switching circuit 6 via the delay circuit 11 in order to guarantee the influence of the time required for APL detection. Other than the above,
The configuration is the same as that of the first embodiment.

According to the present embodiment, while the same effect as that of the first embodiment is obtained, the APL value does not change suddenly even when the generated image is inserted, so that the flicker during the insertion can be reduced.

Example 4. FIG. 4 shows a further improvement of the third embodiment regarding the problem that the inserted image is conspicuous. Figure 4
At, the output of the APL control circuit 10 is the delay circuit 11
Is added by a weighted addition circuit 8 with a predetermined weight, and the output is supplied to the signal switching circuit 6 as an insertion image. The configuration other than the above is the same as that of the third embodiment.

According to the present embodiment, while the same effect as that of the first embodiment is obtained, the APL value does not change suddenly even when the generated image is inserted, and the original video signal is added. And the feeling of strangeness can be reduced.

Example 5. Regarding the problem that the inserted image is conspicuous, the configuration of FIG. 5 is improved by devising the insertion timing. In the figure, a scene change detection switching control circuit 12 is a circuit that receives a video signal and a synchronization signal and detects a scene change point, and supplies this scene change point to the signal switching circuit 6 as a switching signal.

The delay circuit 11 is for ensuring the influence of the time required for detecting the scene change, and the video signal is supplied to the signal switch 6 via the delay circuit 11. The configuration other than the above is the same as that of the first embodiment.

According to this embodiment, while the same effect as that of the first embodiment is obtained, the insertion timing of the generated image is set to the scene change point of the original video signal, so that the change of the original video signal before and after the insertion is large. The flicker and discomfort caused by insertion can be reduced.

The above insertion timing is not limited to the scene change point, but the same effect can be obtained even if the insertion timing is inserted at a point where the APL of the original video signal greatly changes. At this time, when the insertion image is generated according to the third embodiment (FIG. 3), the effect is further enhanced by controlling the APL value of the insertion image so as to be at the midpoint of the change of the APL.

Further, the insertion timing determining method according to the present embodiment can be expected to further improve even if it is combined with the insertion image generating method according to the second to fourth embodiments.

Example 6. Regarding the problem that the inserted image is conspicuous, as another means of devising the insertion timing,
The configuration shown in FIG. 6 also has an improving effect. In the figure, the chaotic switching control circuit 14 receives an irregular signal from the random number generating circuit 13, randomly generates a switching signal based on this signal, and controls the signal switching circuit 6. Other operations and configurations are similar to those of the first embodiment.

In general, regular image fluctuations tend to be visually perceptually perceived. Therefore, by irregularly switching as in the present embodiment, the same effect as that of the first embodiment can be obtained while the insertion is performed. It is possible to reduce flicker and discomfort at the time.

In this embodiment, the generated image is randomly inserted, but the insertion timing may be changed according to the viewing time. For example, it is conceivable that the insertion timing is determined by a chaotic model in which it is inserted regularly at the beginning of viewing and becomes random as time passes. Furthermore, it is possible to change the insertion frequency as the viewing time elapses.

The timing change due to the passage of time is as follows.
It can be expected not only to deal with the problem that insertion is conspicuous, but also to have the effect of inducing and promoting physiological and psychological conditions.

The same effect can be obtained by appropriately combining the insertion timing determination method described in the fifth and sixth embodiments with the insertion image processing method described in the second to fourth embodiments. Needless to say.

Further, it is conceivable that the image rate at the time of insertion is made high and the addressing circuit 2 is also made high in speed to make the period of one frame of the inserted image display shorter to make it inconspicuous. As a modification of the above, by displaying at high speed and displaying the original video signal in a blinking manner or at high speed during the remaining time of the normal one frame period, the discomfort can be further reduced.

Example 7. In the first to sixth embodiments, since the inserted image is displayed only for a moment, there is a problem that it cannot be confirmed even if the generated image other than the original purpose is inserted. FIG. 7 is a configuration diagram for solving the above problem.

In the figure, the video signal, the synchronizing signal, the switching signal, the inserted original image and the inserted image are shown in Examples 1 to 6, respectively.
1 to 6 in FIG. The switching signal includes the AND circuit 17, ex. is supplied to the switching circuit 6 via the OR circuit 16, and the AND circuit 17 and the ex. The other input of the OR circuit 16 has a switch SWa1
9 and the switch SWb18 are connected.

With SWa19, the intermittent insertion function is turned on.
N / OFF can be performed, and SWb enables selection of the video signal side or the inserted image side when the intermittent insertion function is OFF. As a result, it is possible to watch the television in the normal mode or check the contents of the inserted image.

On the other hand, the switching circuit 15 is a circuit for selecting the inserted original image and the inserted image obtained by processing the inserted original image and supplying the selected image to the signal switching circuit 6, and the function corresponding to the second to fourth embodiments. Is. The SWc 20 is a switch for controlling the selection of the above images, and it is possible to intermittently insert any one of the images, or to check the contents when the intermittent insertion is OFF.

Example 8. In Embodiments 1 to 7 described above, an image that is completely unrelated to the video signal is generated from the data storage device 4 and inserted. However, an image in which specific processing is intermittently performed on the original video signal Even if inserted, a specific impression or psychological effect can be given in perceiving the image. FIG. 8 is a block diagram for the above embodiment.

In the figure, a scene change detection / image quality control circuit supplied with a video signal extracts a scene change point of the video signal, and at the change point, the signal processing circuit 1 causes the brightness, contrast, hue, color gain, Various signal processing characteristics such as frequency characteristics are made variable.

According to the present embodiment, for example, by changing the APL value over at the change point of the scene, it is possible to strengthen the impression of the scene change. On the contrary to the above, by gradually changing the APL value at the scene change point, it is possible to reduce a sharp change in brightness and darkness, and it can be expected to have a favorable effect on eye fatigue.

Further, it is expected that the vividness can be emphasized by increasing the color tone when the scene changes, and a good impression to the image quality can be expected.

The delay circuit 11 in the figure is for ensuring the influence of the time required for scene change detection.

[0051]

As described above, according to the present invention, an image that induces / promotes psychological and physiological requirements, or an image that gives a good impression to an image is arbitrarily inserted so that the viewer does not notice. Since it is configured to be possible, there is an effect that it can be used for various purposes such as image improvement, a psychological controller, a psychotherapy device, and the like by the subliminal effect and the like.
