Embodiment
As shown in Figure 1, be the running environment figure of indicator screen system for regulating angle of the present invention preferred embodiment.This indicator screen system for regulating angle 10 runs on display foot rest 1, and this display foot rest 1 is connected on display 2, and this display foot rest 1 can be connected in display 2 by wired connection or wireless network and carry out communication.Described display 2 can be desktop computer display, notebook indicator screen or for the display screen of panel computer etc.In the present embodiment, the user's eyeball of adjusting to of indicator screen angle watches the sight line of display 2 vertically for best, thinks when user vertically watches the screen of display 2, and user's eyes are comparatively comfortable.
Taking lens 11 and infrared ray sensor 12 are installed on described display 2.Described taking lens 11 is for taking the picture of user's eye ball, and this picture is sent to display foot rest 1.Described infrared ray sensor 12 is for detecting the distance between people and display 2.Because infrared ray sensor 12 need to detect user, therefore display 2 descend edge preferably not higher than user's sitting height most, if display 2 descend the sitting height of edge higher than user most, described infrared ray sensor 12 may detect user, also just cannot detect the distance between user and display 2.In this preferred embodiment, described taking lens 11 is arranged on the upper along position of display 2, and described infrared ray sensor 12 is arranged on the lower to position of display 2.
As shown in Figure 2, be the functional block diagram of indicator screen system for regulating angle 10 in Fig. 1.Described indicator screen system for regulating angle 10 comprises: reminding module 100, the first control module 101, the first computing module 102, the second computing module 103, the second control module 104, acquisition module 105 and the 3rd computing module 106.Described module is the software program section with specific function, this software is stored in computer-readable recording medium or other memory device, can be carried out by computing machine or other calculation element that comprises processor, thereby complete the work flow of adjusting the screen angle of display 2 in the present invention.
Reminding module 100 is in the time that user uses described display 2, and prompting eyes of user is looked squarely dead ahead, controls described taking lens 11 and takes user's eyeball, and obtain the first picture of this shooting.This reminding module 100 is also for pointing out user to see taking lens 11, and controls described taking lens 11 and take user's eyeball, and obtains the second picture of this shooting.
The first control module 101 is detected the first horizontal range between user and display 2 for controlling described infrared ray sensor 12, and in this preferred embodiment, this first horizontal range is the horizontal range that user arrives 2 times edges of display.
The first computing module 102 is for calculating the first viewing angle of user according to described the first picture and second picture, this first viewing angle is that user is seeing the direction of visual lines of taking lens 11 and the angle of horizontal direction, θ as shown in Figure 4
a.
The second computing module 103 is for calculating the vertical height between user's eyes and the lower edge of display 2 according to the initial angle between the first horizontal range between the first viewing angle of described user, user and display 2 and current display 2 and display foot rest 1.
The second control module 104 when watching as user the content showing on the screen of display 2, is controlled described taking lens 11 and takes user's eyeball, obtains the 3rd picture of this shooting.
Acquisition module 105 is for according to the position on the screen of the current display of watching 2 of the 3rd picture consumer positioning of taking.
The 3rd computing module 106 needs for watching according to the vertical height between the lower edge of described user's eyes and display and user the angle adjusted between position calculation display 2 on the screen of display 2 and display foot rest 1.
In this preferred embodiment, as shown in Figure 4, described taking lens 11 is arranged on the upper edge of display 2, and infrared ray sensor 12 is arranged on the lower edge of display 2.The first viewing angle that the first computing module 102 calculates user according to described the first picture and second picture is θ
a, the first horizontal range that infrared ray sensor 12 is detected before user and display 2 is X1, the initial angle between display 2 and display foot rest 1 is θ
1, the width of display 2 is L.Horizontal range between user and the upper edge of display 2 is X2=X1+L*cos θ
1, the vertical height H 1=X2*tan θ on the upper edge of display 2 described in user's eye distance
a.The upper edge of display 2 is to the vertical height H 2=L*sin θ on lower edge
1, the vertical height H=H1+H2 between described user's eyes and the lower edge of display 2.
After the vertical height calculating between user's eyes and the lower edge of display 2, user can arbitrarily watch the content showing on display 2.Now described taking lens 11 is taken user's eyeball, obtains the 3rd picture.If what user watched is the center of the screen of display 2, example this center is as shown in Figure 5 1/2 width place of display 2.The 3rd computing module 106 calculates the horizontal range X3=X1+0.5L*cos θ between user and the screen center position of this display 2
1, user's eyeball is to the vertical distance H 3=H1+H2-0.5L*sin θ between the screen center position of described display 2
1, in the 3rd picture, user watches the second viewing angle θ of display 2
b=tan
-1(H3/X3), the angle between described display 2 and display foot rest 1 need to be adjusted into θ
2=90-θ
b.
As shown in Figure 3, be the operation process chart of indicator screen angle adjusting method of the present invention preferred embodiment.
Step S30, in the time that user uses described display 2, reminding module 100 points out eyes of user to look squarely dead ahead, controls described taking lens 11 and takes user's eyeball, and obtain the first picture of this shooting.
Step S31, this reminding module 100 points out user to see taking lens 11, controls described taking lens 11 and takes user's eyeball, and obtain the second picture of this shooting.
Step S32, the first control module 101 is controlled described infrared ray sensor 12 and is detected the first horizontal range between user and display 2, and in this preferred embodiment, this first horizontal range is the horizontal range that user arrives 2 times edges of display.
Step S33, the first computing module 102 calculates the first viewing angle of user according to described the first picture and second picture, and this first viewing angle is that user is seeing the direction of visual lines of taking lens 11 and the angle of horizontal direction, as shown in Figure 4.
Step S34, the second computing module 103 calculates the vertical height between user's eyes and the lower edge of display 2 according to the initial angle between the first horizontal range between the first viewing angle of described user, user and display 2 and current display 2 and display foot rest 1.
Step S35, in the time that user watches the content showing on the screen of display 2, the eyeball that the second control module 104 is controlled described taking lens 11 and take user, obtains the 3rd picture of this shooting.
Step S36, acquisition module 105 is according to the position on the screen of the current display of watching 2 of the 3rd picture consumer positioning of taking.
Step S37, the 3rd computing module 106 is watched according to the vertical height between the lower edge of described user's eyes and display and user needs the angle adjusted between position calculation display 2 on the screen of display 2 and display foot rest 1.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not depart from the spirit and scope of technical solution of the present invention.
