[0016] The picture conversion device 400 is connected to the conversion computing device 300 and display 1〇〇, for receiving the tilt angle from the conversion computing device 3〇〇, and then rotating and zooming according to the tilt angle to adjust the display data displayed on the display 1〇〇 to generate the adjusted display data. The adjustment display data is displayed on the display The display screen in 1〇〇 includes all the contents of the display material, and the display screen rotates by a corresponding angle corresponding to the tilt angle. That is, the display screen rotates the corresponding angle corresponding to the left and right tilt of the user's face. The face conversion device 400 includes a conversion module 402 and a zoom module 4〇4. 0982073402-0 098142734 Form number A0101 page β/total π page 201120867 [] The conversion pull group 402 is connected to the conversion computing device 3 Between the zoom modules (10), for receiving the tilt angle, and then adjusting the display data transmitted to the display 100 according to the tilt angle rotation to generate an intermediate display data and The intermediate display data is transmitted to the zoom module 404. [0018] Referring to FIG. 3, in the present embodiment, the conversion module 4〇2 is predetermined to have a corresponding rotation relationship. Specifically, if the connection 5〇〇 is located on the horizontal line 502 Above, the angle 7 is positive; on the contrary, the angle π is negative. When _15. " <15., the display screen of the display 100 is normally displayed, wherein the normal display refers to the display surface of the display 100 without any angle Rotation adjustment; when 15» <45, the display rotates to a position with the horizontal angle of 3〇. When 45.$?? <75°, the ridge horizontal line 5〇2 is displayed at an angle of 60°. The position of the reading screen is rotated to an angle of -30 degrees from the horizontal line 502; when a 75. $ π < _45 is displayed, the display is rotated to an angle with the horizontal line 502 - [0019] Of course, the rotation relationship is not limited to the present embodiment: it can be preset by the manufacturer and allows the user to edit the settings by himself. For example, the user can edit the conversion relationship so that: when -5 ° S 7? < 5°, the display is displayed normally; when 5° S w < 15°' The display screen is rotated to a position at an angle of 10 ° to the horizontal line 5 〇 2. [0020] The zoom module 404 is connected between the conversion module 402 and the display 100 for receiving the intermediate display data and then scaling the intermediate display data. To generate the adjusted display data, please refer to Figure 4, adjusting the display data so that the display screen 450 of the display 100 is rotated by a corresponding angle corresponding to the tilt angle, for example, 30. At least two of the four endpoints of the display screen 450 are located. The endpoints 452, 454 on the same diagonal line are located on the two edges 422, 424 of the display ι 〇〇 119142734 Form No. Α 0101 Page 7 / Total 17 Page 0982073402-0 201120867, so that the contents of the display data can be fully Displayed in display 100. Wherein, the edges 422, 424 are parallel to the lateral coordinates of the picture when the display 100 is normally displayed, i.e., parallel to the horizontal line 502. [0025] [0025] Of course, the zoom mode may not be limited to the present embodiment as long as the display data can be displayed in all directions. For example, the intermediate display material can be scaled such that the endpoints 452, 454 of the display screen 450 are located within the two edges 422, 424 opposite the display 100, i.e., the display screen is made smaller. Referring to FIG. 5, a preferred implementation method for automatically adjusting a display screen of the present invention includes the following steps: Step S1: Acquiring a digital image of a user's face. The face digital image has a horizontal edge parallel to the abscissa axis of the display face of the display 100. Specifically, the image capture device 200 captures a user's face digital image. In step S2, the angle of the line of the image portion of the two eyes in the face digital image with respect to the horizontal edge is analyzed. Specifically, the conversion computing device 300 extracts the position of the image portion of the eye from the facial digital image and then calculates the line 500 and the horizontal line 5 representing the horizontal edge based on the line 500 of the position of the image portion of the eye.夹 2 angles, that is, the angle of inclination. The tilt angle signal is sent to the kneading device 400. Step S3, according to the tilt angle rotation adjustment, the display presents the display material of the display screen to generate an intermediate display material. Specifically, the screen switching device 400 receives the tilt angle signal, and then rotates the display data transmitted to the display 100 in accordance with the tilt angle to produce 098142734 Form No. A0101 0982073402-0 201120867. [0026] Step S4, zooming and adjusting the intermediate display data to generate adjusted display data. The display of the adjustment display data in the display includes displaying the entire contents of the data, and the display 旋转 is rotated by the corresponding angle at an oblique angle. Specifically, the kneading device 400 performs zoom adjustment on the intermediate display material to generate an adjusted display material. [0027] In step S5, the kneading device 400 transmits the adjusted display data to the display.
