Material, when the eyes of the people please the eyes of the people = located in the (four) silk 3 front selection em J ^ human eyes on the module · judgment of the human eye appears within the specified distance. When the position of the discriminating person is located within an angle of _6 至 to +6 偏 from the vertical direction of the display screen 3, the human eye recognition module 102 determines that the angle of view of the human eye is within the specified angle. The counting module 1〇3 is used to set and initialize a time counter value (tuner) 'This time count value is increased by "1" every second when the human eye does not appear within the specified range, and the time count value is detected immediately. The size. For example, 'time count value timer is initialized to leap second. The display mode execution module 104 is configured to select a corresponding display mode for the display screen 3 according to the size of the time count value. For example, when the time count value is less than the first pre-riding interval (for example, 1G seconds), the display mode execution module 1〇4 is display 7: the screen selects the normal display mode; when the time count value is greater than or equal to the first preset time and When it is less than the second preset time (for example, 6 seconds), the display execution module 104 selects the screen protection mode for displaying the camp 3; when the field time value is greater than the second job time, the mode execution mode is The group (10) selects the power saving mode for displaying the screen 3, and automatically displays the display screen 3 in the present embodiment.

In this embodiment, photography = inside: shadow 3 in front and off and display the vertical direction of the egg screen 3: display: curtain degree to +6 degree area The images of _ are all valid images. Also, no = 7= In the image of the borrowing: The eye recognition technology determines whether there is any eye in the image. If 2 people have the human eye in the image, then the image is right中中&β $ φ appears within the specified distance according to whether the person is in the target or not (step 1 'when the position of the human eye is detected is within the display screen 3 within 6^^' Specify = If the human eye is in the image, step S34). For example, if the distance is within the specified distance, the human eye recognition module 1〇2 determines whether the human eye angle is within the specified angle according to the position (X沭, when recognized The position of the human eye is located within -60 degrees to +60 from the vertical direction of the display screen 3 9 201009565, and the human eye recognition module 102 determines The eye angle of view is within a specified angle. ^ If the human eye is within a specified angle, the display mode execution module 104* selects a normal display mode for the display screen 3 (step S35), and the flow returns to step S30. In step S32, If the human eye does not appear in the image, the counting module 103 increments the time count value timer by "1" every second, that is, the time count value is calculated as timer=timer+l (step S36). In step S33, If the _ human eye does not appear within the specified distance, step S36 is performed. In step S34, if the human eye angle of view is not within the specified angle, step S36 is also performed. The counting module 103 judges whether or not the time count value is greater than or equal to 10 seconds (step S37). If the time count value is less than 10 seconds (ie, timer < 10), the flow returns to step S31; if the time count value is greater than or equal to 10 seconds (ie, timei^10), the counting module 103 determines whether the time count value is greater than or equal to 60 seconds ( Step S38). If the time count value is less than 60 seconds (ie, 10Stimer < 60), the display mode execution module 104 selects the screen save mode for the display screen 3 (step S39), and the flow returns to step S31; if the time count value is greater than or equal to 60 seconds ( That is, timer^60), the display mode execution module 104 selects the power saving mode for the display screen 3 and automatically turns off the display screen 3 (step S40), and the flow returns to step S31. The screen shown in FIG. 3 above shows the flow of the energy saving method. Once the user starts the screen display, the energy saving system 10 starts, and the computer 1 is executed to track whether the user uses the computer 1. Only when the user turns off the screen to display the energy saving system 10 End. 201009565 Finally, it should be noted that the screen display energy-saving system and method of the present invention automatically determines whether the user uses the computer 1 by using the recognition and tracking function of the camera 2 to timely display the display screen 3 into a power-saving mode. This avoids the drawback of detecting how long the keyboard and mouse have not been used. In addition, the screen display energy-saving system and method can also be used to achieve other functions to meet the increasingly important environmental requirements, such as: anti-peep judgment, that is, if the camera detects the second pair of eyes, the display screen 3 can be dimmed Prompt or issue a warning; if used on a TV set, it can be used as a limit, 蠼 viewing distance function.
