Describe the present invention below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.
Detailed description of the invention
Fig. 1 is the environment schematic of electronic display unit 100 1 embodiment of the present invention.In the present embodiment, user
The front end of 20 display screens 105 being in electronic display unit 100, electronic display unit 100 presents display picture by display screen 105
Face 50, display picture 50 is the display screen 105 region for show image, and the area of display picture 50 is a fixed value;Shooting
The user 20 of 101 picked-up display screen 105 front ends, calculates the area of user 20 and the ratio of the area of display picture 50, according to
The ratio range that described ratio falls into selects a user interface and presents to use by selected user interface by display screen 105
Family 20.Wherein, the area of the user image 20a that the area of described user 20 is absorbed by photographic head 101, user image 20a's
Area can be used for positioning the area of the rectangle frame (as shown in dotted outline in FIG.) of user by calculating photographic head 101 and draw.
In the present invention one specific embodiment, it is aobvious that electronic display unit 100 can be that intelligent television or computer etc. have
Show that the equipment of function, described photographic head 101 can embed electronic display unit 100 or be placed on electronic display unit 100
Common camera (Camera), IP Camera (WebCamera/CoolCamera) or other there is first device of camera function
Part.
When Fig. 2 is that in embodiment of the present invention, same user 20 is in diverse location, electronic display unit 100 selects difference
The schematic diagram of user interface.In the present embodiment, electronic display unit 100 can be according to remote apart from display screen 105 of user 20
Closely from multiple user interfaces, select suitable user interface.Wherein, user image 20a, user image 20b and user image
The user image that when 20c is in the diverse location of display screen 105 front end by user 20, photographic head 101 is absorbed, described user 20
Area i.e. refer to the area of user image, wherein, the varying in size of user image when user is in diverse location, i.e. user 20
Area is different.In the present embodiment, the corresponding multiple ratio ranges of multiple user interfaces, ratio range refers to that photographic head 101 is taken the photograph
The area of the user image taken is relative to the scope of the ratio of the area of display picture 50.
For example, it is assumed that the size of display screen 105 is 42 inches, corresponding multiple user interfaces include succinct interface
40a, normal interface 40b and exquisite interface 40c.Succinct ratio range corresponding for interface 40a is less than or equal to first threshold, just
Ratio range the most corresponding for interface 40b is between first threshold and Second Threshold, exquisite ratio range corresponding for interface 40c
For more than or equal to Second Threshold.Wherein, first threshold is less than Second Threshold, can be respectively 3% and 6%.
When distance between user 20 with electronic display unit 100 is bigger (such as larger than 2.75 meters), electronical display sets
The standby 100 user image 20a absorbed by photographic head 101 are smaller, correspondingly, and area (the i.e. user of the user 20 absorbed
The area of image 20a) smaller relative to the ratio of the area of display picture 50, as being 2.5%, described ratio is less than first
Threshold value (3%), is i.e. in succinct ratio range corresponding for interface 40a, and correspondingly, electronic display unit 100 selects described ratio
The succinct interface 40a that value scope is corresponding.The content that described succinct interface 40a is presented is less, and the font of displayed information compares
Greatly, user 20 is facilitated can to see the clearest in remote position.
When distance between user 20 and electronic display unit 100 is moderate (as between 1.65-2.75 rice), electronic display
Show that the user image 20b that equipment 100 is absorbed by photographic head 101 is of moderate size, correspondingly, the area of the user 20 absorbed
(i.e. the area of user image 20b) is moderate relative to the ratio of the area of display picture 50, and as being 5.1%, described ratio is situated between
Between 3% and 6%, being i.e. in ratio range corresponding to normal interface 40b, correspondingly, electronic display unit 100 selects institute
State the normal interface 40b that ratio range is corresponding.The content that described normal interface 40b is presented is more, facilitates user nearer
Position can be seen the clearest and can obtain more information.
During close together between user 20 and electronic display unit 100 (such as less than 1.65 meters), electronic display unit
The 100 user image 20c absorbed by photographic head 101 are bigger, correspondingly, and area (i.e. user's shadow of the user 20 absorbed
As 20c) relatively big relative to the odds ratio of the area of display picture 50, as being 7.5%, described ratio is more than 6%, is i.e. in essence
Causing in ratio range corresponding to interface 40c, correspondingly, electronic display unit 100 selects the exquisite boundary that described ratio range is corresponding
Face 40c.The content that described exquisite interface 40c is presented is most, and picture is exquisite, facilitates user can obtain more information.
It should be noted that, be only electronic display unit 100 of the present invention shown in Fig. 2 to select the concrete of different user interface
Embodiment, the invention is not limited in this, needs to design more different user interface according to difference, and, according to difference
The size of display screen, can adjust the ratio range of user's area and the area of display picture.
Fig. 3 shows the module map of electronic display unit 100 1 embodiment of the present invention.As it is shown on figure 3, electronical display sets
