As shown, the key input unit 10 generates various operation signals for driving the image reproducing apparatus according to the user's operation and outputs them to the microcomputer 20.

In this case, the key input unit 10 generates a key signal according to the user's manipulation of various keys provided in the video reproducing apparatus main body or various keys provided in the remote controller, and outputs them to the microcomputer 20.

The microcomputer 20 controls the performance of various operations of the image reproducing apparatus according to the key signal input from the key input unit 10, and the time set for power control (the time set arbitrarily and can be arbitrarily adjusted by the user) is controlled. If the operation signal of the image reproducing apparatus is not input through the key input unit 10 until the elapsed time, the luminance amount detection signal according to the light emission of the display unit 40 input from the sensor 50 and the reference signal for turning off the image reproducing apparatus The control unit 100 generates a power control signal for reducing the luminance of the display unit 40 or a control signal for turning off the image reproducing device according to the comparison result, and outputs the control signal to the power control unit 30.

That is, when the detection signal input from the detection sensor 50 is higher than the reference signal for turning off the image reproducing apparatus, the microcomputer 20 generates a power control signal for reducing the amount of luminance of the display unit 40 and detects the detection signal. When the detection signal input from the sensor 50 is equal to or lower than the reference signal for turning off the image reproducing apparatus, the user recognizes that the user is sleeping and generates a control signal for turning off the image reproducing apparatus.

The power controller 30 is a part for supplying power for the operation of the image reproducing apparatus. When the power control signal for reducing the luminance amount is input from the microcomputer 20, the power controller 30 reduces the current supplied to the display unit 40 to display the display unit ( When the control signal for turning off the image reproducing device is input from the microcomputer 20, the power supply is cut off to turn off the image reproducing device.

The display unit 40 is an operation state of an image reproducing apparatus according to a user's key operation. The display unit 40 is multi-stage according to the control of the power control unit 30 that receives a power control signal for reducing the luminance from the microcomputer 20. To adjust the brightness (adjust the brightness gradually lower in the normal state).

The sensor 50 detects the amount of luminance emitted from the display unit and outputs the amount of luminance to the microcomputer 20.
