Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a television embodying a theater atmosphere.

2 is a flowchart of a procedure for implementing a theater atmosphere.

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 into an intermediate frequency that 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. The image signal output through the image signal processor 25 includes an image amplifier circuit for amplifying the luminance signal after detecting the luminance, a band amplifier circuit for selecting and amplifying a carrier color signal from the image signal, and a carrier color signal applied from the band amplifier circuit. The image output unit 35, which is composed of a demodulation circuit that combines the luminance signals applied from the image amplification circuits and generates the color signals required for display on the screen, is a CRT (video signal) suitable for output to the screen by the action of each circuit described above. 85). The voice signal output through the voice signal processor 30 is amplified to a size suitable for output from the voice output unit 40 and output to the speaker 45. In addition, when a viewer watches a movie, the illuminance sensor 50 measures illuminance and illuminates the illuminance to a lux (Lx) value. 55 outputs an illuminance signal applied from the illuminance detection sensor 50 to the determination unit 65 as a lux (Lx) value. The illuminance value applied by the illuminance judging unit 55 is stored in the image environment memory unit 60 by the judging unit 65, and the contrast, brightness, and color set for each illuminance value are determined. The data of the video environment means suitable for the illuminance value is selected from the data of the video environment means such as sharpness and the like, and the data is output to the microcomputer 70. The microcomputer 70 receiving the data of the image environment means output from the determination unit 65 may control the contrast, brightness, color, sharpness, etc. of the image output unit 35. Adjust the video environment means according to the data to complete the setting of the screen. The microcomputer 70 controls the screen and simultaneously sets the surroundings of the viewer, such as "close the window", "close the curtain", and "turn off the light" stored in the message memory unit 75. The command message can be output to the CRT 85 through the OSD 80 so that the viewer sets a surrounding environment according to the command message to implement a theater atmosphere.

A procedure for implementing a theater atmosphere in the above process will be described below with reference to the flowchart of FIG. 2.

When the viewer watches a movie through the television, the viewer switches the movie input button to set the video environment and the surrounding environment according to the movie (S100). In order to measure the current light intensity after the step S100, the illuminance sensor 50 measures illumination (illumination) (S200). After the step S200, the illuminance determining unit 55 determines how much the illuminance value is to output the measured illuminance as the Lx value (S300). After the step S300, the determination unit 65 determines the image environment such as contrast, brightness, color, and sharpness, which are determined according to the illuminance values and stored in the image environment memory unit 60. The data of the video environment means corresponding to the illuminance value measured from the data of the means is selected and output to the microcomputer (S400). After the step S400, the image output unit 35 adjusts the contrast, brightness, color, sharpness, etc. according to the data of the selected image environment means under the control of the microcomputer 70. Adjust to set the screen according to the theater atmosphere (S500). After the step S400, the OSD 80 "closes the window", "close the curtain", "stored in the message memory unit 75 in order to allow the viewer to set the external environment under the control of the microcomputer 70. Turn off the light "to output a command message, such as to the CRT (85) via the OSD (80) screen (S600).

Through all the above processes, the television embodying the theater atmosphere is implemented as the present invention intends.

As can be seen from the above description, the present invention can detect the light intensity of the light intensity sensor to detect the current light intensity in order to implement a cinematic atmosphere when viewers watch a movie through a television To measure the intensity of light, and to refer to the data of the image environment means stored in the image environment memory unit such as contrast, brightness, color, sharpness, etc. Select the data of the video environment means corresponding to the measured illuminance value and adjust the video environment means of the video output unit according to the selected data to set the screen, and at the same time, "Close the window", "Close the curtain", In order to output a command message such as "Turn off the light", the message is stored in the message memory unit and the stored message is displayed on the screen by the OSD function when watching a movie. This is an effect that can make a video environment and surroundings into the atmosphere, such as a movie theater when watching the movie to let viewers through the television set by the surrounding environment.
