Summary of the invention
Purpose of the present invention overcomes the deficiencies in the prior art exactly, and a kind of method of automatic adjusting screen display size is provided, and adopts the method can help child to form the good custom of watching, and prevents to a certain extent child's myopia.
In order to achieve the above object, adopt following technical scheme:
A kind of method of automatic adjusting screen display size may further comprise the steps realization:
S1. at display the distance sensing device is set, described distance sensing device is for detection of the distance between human body and the indicator screen;
S2. in server, set human body to the distance of indicator screen and the mapping table between the screen display ratio;
S3. the distance sensing device cooperates server that the distance between human body and the indicator screen is detected;
S4. the mapping table among the Distance query step S2 that obtains according to step S3 of server, and according to the display size of Query Result command display adjusting screen.
Further, described distance sensing device be infrared ray distance measurement instrument or camera,
As a kind of specific embodiment, among the described step S2, the screen display ratio is with the stepped distribution of variation of human body and indicator screen distance.
As a kind of specific embodiment, described distance sensing device is camera.
As a kind of specific embodiment, described step S3 may further comprise the steps again:
S31, when have the people near the time, the camera pictures taken;
S32, server carry out recognition of face based on the picture that obtains among the step S31;
S33, server calculate the ratio that the human face pixel accounts for the total pixel of photo current;
S34, the ratio that obtains according to step S33 are calculated the distance between human body and the indicator screen.
Compared with prior art, beneficial effect of the present invention is:
At display the distance sensing device is set, makes computer can zoom in or out according to the distance between human body and the indicator screen display size of screen, can be used for helping child to form the good custom of watching on the one hand, prevent to a certain extent child's myopia; Also can amplify display size on the normal basis that shows on the other hand, auxiliary the elderly watches.

Fig. 4 be among the embodiment 2 human body from the distance of indicator screen screen display scope schematic diagram during greater than 50mm.
Among the figure: the 1-display; The 11-viewing area; 12-infrared ray distance measurement instrument; The 13-background area; The 14-camera.The 2-server.
Embodiment
Below in conjunction with drawings and the specific embodiments, the present invention will be further described:
Referring to Fig. 1-Fig. 3, the method for a kind of automatic adjusting screen display size of the present invention is characterized in that, may further comprise the steps realization:
S1. at display 1 the distance sensing device is set, described distance sensing device is for detection of the distance between human body and the indicator screen.
In automatic field, utilize sensor to adjust the distance and detect the usually technology of usefulness of right and wrong, distance measurement sensor commonly used has infrared ray distance measurement instrument, ultrasonic distance detection instrument, laser distance detection etc., for human body is produced minimum impact, be preferably infrared ray distance measurement instrument 12 in the present embodiment, this infrared ray distance measurement instrument 12 is arranged at the display top, and the screen of the end face of its sensor and display 11 is roughly in the same plane.
S2. in server 2, set human body to the distance of indicator screen and the mapping table between the screen display ratio.
In order to adapt to different users's needs, the corresponding relation between human body and indicator screen distance and the screen display ratio need to be set in server 2, table 1 has provided one group of reference data of above-mentioned corresponding relation.
| Human body is to the distance of indicator screen | ＞50mm | 35mm-50mm | <30mm |
| The screen display size accounts for the number percent of screen overall dimensions | 100% | 75% | 50% |
Table 1
S3. the distance sensing device cooperates the distance between 2 pairs of human bodies of server and the indicator screen to detect.
When server 2 is positioned under the duty, computer user near the time, the distance that infrared ray distance measurement instrument will detect is transferred on the server 2 with digital form, this detection can be intermittence, also can be continuous signal.
S4. the mapping table among the Distance query step S2 that obtains according to step S3 of server 2, and according to the display size of Query Result command display adjusting screen.
The signal that receives in 2 pairs of previous steps of server is analyzed, this analytic process mainly be with step S3 in the reference data set compare, take human body by far away and advance to display 1 near as example, when the distance between human body and the indicator screen constantly changes, the display size of server instruction display 1 is also made corresponding adjustment thereupon, referring to figure, 1, Fig. 2 and Fig. 3, wherein 11 is the actual displayed district, and 13 is background area, and background area 13 is adjusted to black usually, in the present embodiment, the screen display ratio is with the stepped distribution of variation of human body and indicator screen distance.
Should be appreciated that, except the concrete element and principle of work of the present embodiment middle distance sensing apparatus, the other guide in the present embodiment is fit to other embodiment of this instructions too.
The present embodiment is from the different of embodiment 1, distance sensing device in the present embodiment is camera, this camera can be external, also can utilize the built-in camera of display 14, in order to realize the detection to distance between human body and indicator screen, needs in the server 2 that image processing software is set the image that camera 14 obtains is analyzed, and according to the distance between Analysis result calculation human body and the display screen, the below discloses a kind of concrete method:
S31, when have the people near the time, camera 14 pictures taken;
S32, server 2 carry out recognition of face based on the picture that obtains among the step S31;
S33, server 2 calculate the ratio that the human face pixel accounts for the total pixel of photo current;
S34, the ratio that obtains according to step S33 are calculated the distance between human body and the indicator screen.
Certainly, in above-mentioned steps 3, server can obtain the reference data that face's area (human face pixel quantity) accounts for picture total area (the total pixel of picture) ratio according to prior experiment, and then step S34 can directly calculate target range according to this reference data.
Should be appreciated that; the content that above specific embodiment is announced only is part preferred version of the present invention; do not consist of the direct restriction to protection domain; application of the present invention also can be amplified display size on the normal basis that shows; so that the watching of the elderly; in a word, every based on technical scheme of the present invention, technical spirit according to the invention, belonging to those skilled in the art, to need not to carry out creative work be that available enforcement all should belong to protection scope of the present invention.
