In other words, the automatical coloring arrangement-method display method using a temperature sensor that emphasizes the blue color scheme in summer, uses the existing color scheme in spring and autumn, and emphasizes the red color scheme in winter. the temporature sensor in each season) and its apparatus.

The conventional color television uses the following method in the screen color distribution method. That is, the video signal applied from the video signal processor is applied to the demodulation circuit section via the A / V switching section. The video signal applied to the demodulation circuit unit has a carrier color signal, and the carrier color signal is a signal including color and saturation information, and a demodulation circuit having two or three demodulation axes as a method for reducing the carrier color signal to a color difference signal. There is. Here, the screen color scheme will be described based on a demodulation circuit having three demodulation axes which are frequently used for convenience. The demodulation circuit having three demodulation axes demodulates the carrier color signal in three axes of the R-Y demodulator, the G-Y demodulator, and the B-Y demodulator, respectively. In addition, to detect the color difference signal from the carrier color signal, a color carrier of 3.58 MHz is required, and the color carrier is supplied with a color phase circuit previously adjusted to a predetermined phase to generate an appropriate color difference signal. The color difference signal demodulated through this process is combined with the luminance signal (Y) from the image amplification circuit unit as the RY signal, the GY signal, and the BY signal, and the final red (R), green ( G), the three primary colors of blue (B) are transmitted.

The color of the image signal displayed on the receiving tube is composed of three colors of red (R), green (G), and blue (B) as a whole. The existing method in combining the colors considers the temperature and the season. Has always implemented a constant color without However, since human emotions are different from each other depending on the season and temperature, even the same color has a characteristic of accepting different feelings depending on temperature and season. In particular, red adds a hot feeling in summer and blue adds a cool feeling in winter. The difference in color perception according to the season of the person is a problem that has been overlooked in the conventional color television technology.

Therefore, the present invention is to solve the problems of the prior art, an object of the present invention is equipped with a sensor for detecting the temperature change according to the season on color television, by recognizing the temperature corresponding to each season in the temperature discriminating unit By outputting the appropriate signal value to the microcomputer, the microcomputer controls the brightness of the image amplifier and the color compensator to give cool colors in summer, traditional colors in spring and autumn, and warm colors in winter. The present invention provides a display device and method for automatically realizing a screen color suitable for a season.

FIG. 2 is a block diagram of a color correction circuit that is an essential part of FIG. 1.

Figure 3 is a flow chart of the automated color scheme according to the present invention.

Referring to FIG. 1, the high frequency signal applied through the antenna 10 is applied to the tuner circuit unit 15, and the tuner circuit unit 15 is applied to a channel selected from the high frequency signals applied through the antenna 10. The corresponding high frequency signal is converted and amplified into an intermediate frequency which is easily amplified by the intermediate frequency amplifier 20 to generate a composite video signal. The composite video signal is detected as a video signal and an audio signal through the video signal processor 25 and the audio signal processor 30.

An A / V switching unit 35 is connected to the video signal processing unit 25 and the audio signal processing unit 30, and the A / V switching unit 35 is an image signal processing unit 25 and an audio signal processing unit 30. It switches and outputs video and audio signals applied from.

In addition, although the video signal and the audio signal output from the A / V switching unit 35 are output through the demodulation circuit unit 40, the audio signal is output through the speaker after the voice demodulation, the video signal is a new image through the following process; Implement

In order to generate a signal according to the temperature, the temperature sensor 60 first recognizes the external temperature and sends a signal corresponding to the value to the temperature discriminating unit 65. The temperature discriminating unit 65 may recognize the signal from the temperature sensor 60 in three stages. That is, -10。C ~ 10。C, which is the temperature corresponding to winter, is "10" value, and 10。C ~ 20。C, which is the temperature corresponding to spring and autumn, is "0" value, which is winter temperature A 20 ° C to 40 ° C outputs a value of "1". In the method of recognizing each signal by the temperature discriminating unit 65, the temperature discriminating unit is configured with OPAMP, and the bandwidth is determined in three stages of the current value sent in response to the temperature from the temperature sensor, so that the temperature corresponds to winter. If the temperature is -10 ° C to 10 ° C, a low current value is output from the temperature sensor 60, and the temperature discrimination unit 65 is a signal value of "10" as a response signal to the current value corresponding to the temperature. Send to the microcomputer (70). Similarly, if the temperature corresponding to the spring and autumn 10。C ~ 20。C a somewhat higher current value than the winter is output from the temperature sensor 60, the temperature discrimination unit 65 to the current value corresponding to the temperature The signal "0" is sent to the microcomputer 70 as a response signal. Finally, when the temperature corresponding to the summer 20 ° C ~ 40 ° C the highest current value is output from the temperature sensor 60, the temperature discrimination unit 65 is a response signal for the current value corresponding to the temperature Sends a "1" signal value to the microcomputer 70. The microcomputer 70 recognizes a signal value input from the temperature discriminator 65 to the microcomputer 70 and controls the luminance amount of the image amplifier and the color compensator for each signal value. A method of controlling the amount of luminance will be explained by the flowchart shown in FIG.

As shown in FIG. 3, the temperature sensor 60 performs an external temperature detection (S100) and sends the signal value to the temperature discriminating unit 65 to determine which temperature the temperature belongs to (S200), and the result value of the microcomputer 90 Output to The microcomputer 70 determines which season corresponds to the result of the temperature discriminating unit 65 (S300). When the microcomputer 70 corresponds to the summer "1", the microcomputer 70 includes an image amplifying unit ( 45) and the luminance amount of the color compensator 50 is changed. That is, in summer, the temperature is high, so it feels hot. Therefore, the brightness of blue should be increased to make it feel cool. Similarly, when the result value is "10" corresponding to winter, the microcomputer 70 changes the luminance amounts of the image amplifier 45 and the color compensator 50. That is, in winter, the temperature is low, so it feels cold. Therefore, the luminance of red should be increased to allow a warm feeling. In more detail with reference to FIG. 2, in order to increase the luminance of the image amplification unit, the voltage of the image amplification circuit is increased. In the conventional color television, the luminance signal of the image amplification unit is a color difference signal as one line during triaxial demodulation. Since it is connected to, the same amount of luminance is applied to each demodulation axis. However, technically, in order to emphasize one of the three primary colors of red (R), green (G), and blue (B), a larger amount of luminance is applied to each demodulation axis to be emphasized. In order to achieve the above object, two separate image amplifiers (image amplifier 45 and color compensator 50) are required, and two image amplifiers (image amplifier 45 and color compensator 50) are required. A color correction circuit consisting of) serves its purpose. As shown in FIG. 2, the color compensator 50 is connected to the R-image output unit R, the G-image output unit G, and the B-image output unit B in three lines. The carrier color signal amplified from the band amplification circuit (A) is output to the image output unit as a color difference signal through a demodulation circuit unit (RY demodulation unit (C), GY demodulation unit (D), BY demodulation unit (E)) (40). When the color compensator 50 needs to emphasize the color, the luminance signal of the color difference part, the image amplification part, and the luminance signal output from the color compensator 50 are output to the image output unit. Are added together to correct the color to be emphasized, and the color compensator 50 is applied to the BY color difference signal when the blue color corresponding to the spring corresponding to the summer is to be emphasized under the control of the microcomputer 70. By applying Y (luminance signal) as much as the amount of luminance to be emphasized, the color signal corrected through the B-image output unit B is generated by receiving the luminance signal of the color compensator 50 together with the image amplifying unit 45 and generating a blue color. Blue correction (S400) for darkening the color is performed. At this time, of the three lines of the color compensator 50 connected to the image output unit 55, all of the lines other than the B-image output unit B are turned off under the control of the microcomputer 70. When the color compensator 50 is under the control of the microcomputer 70 and needs to emphasize the red color corresponding to the winter, the color compensator 50 applies Y (luminance signal) as much as the amount of luminance to be emphasized to the RY color difference signal to amplify the image. At the same time as the unit 45, a color signal corrected through the R-image output unit R is generated by receiving the luminance signal of the color compensator 50, and a red color correction S500 is performed to darken the red color. Similarly, of the three lines of the color compensator 50 connected to the image output unit 55, all lines other than the R-image output unit R are turned off under the control of the microcomputer 70. Finally, the image amplification unit 45 controls the microcomputer 70 as it is in the original way in the case of spring and autumn which do not make a difference with the existing color, so that all lines of the color compensator 50 are turned off. The luminance signal Y of (45) is applied to each of the color difference signals RY color difference signal, GY color difference signal, and BY color difference signal to output each color signal of R (red), G (green), and B (blue). The standard screen S600 is displayed through the image output unit, the G-image output unit, and the B-image output unit. The color signal demodulated through the above process is supplied to the respective cathodes of the water pipe 75 to form a display (S700) on the screen.

After all the above process, different screen color schemes are automatically implemented according to the temperature as the present invention intends to display a screen suitable for the characteristics of each season.

As can be seen from the above description, the present invention adds a temperature sensor to a conventional color television, and the temperature discriminating unit determines the season corresponding to each temperature by applying a current signal from the temperature sensor and applies each signal value to the microcomputer. Then, the microcomputer controls the luminance level of the image amplifier and the color compensator, and when the red is emphasized, it supplies Y (luminance signal) as much as the color compensator emphasizes the RY color difference signal and combines it with the luminance signal from the image amplifier. Red correction is performed to generate the corrected color signal through the output unit, and displays red-oriented displays. When blue is emphasized, the luminance signal from the image amplification unit is supplied by supplying Y (luminance signal) as much as the color compensator emphasizes the BY color difference signal. In addition, the blue color correction is performed to generate the corrected color signal through the B-image output unit. Spring and autumn are still displayed without a change in the amount of Y (luminance signal), there is an effect that it is possible to display each with different color in vision teolre screen according to the season to.
