Description
Technical Field
The invention relates to the field of multi-screen display, in particular to a method and a device for realizing accurate screen projection.
Background
In the traditional sense, multi-screen interaction refers to the application of an intelligent grouping and resource sharing protocol, a Miracast protocol and the like, through WiFi network connection, on different multimedia terminals (such as different intelligent terminal devices based on different operating systems such as Ios, Android, Symbian and the like, for example, mobile phones, PADs, TVs and the like), a series of operations such as transmission, analysis, display, control and the like of multimedia (audio, video and picture) contents can be carried out, the display contents can be shared on different platform devices at the same time, and the multimedia life of users is enriched. In short, the screens of several devices can be mutually connected and converted through special connecting devices. For example, a movie on a mobile phone can be played on a television, pictures on a tablet can be shared on the television, and the content of a computer can be projected on the television, which is a technique that is being invisibly created at present.
In view of the popularity and the universality of multi-screen interaction at present, when a device is used for wirelessly projecting screens to another devices, the corresponding relation between a physical environment display screen and a controlled display screen in software is quite easy to be disordered, and the generated adverse effect is that the display material cannot be accurately projected on the correct display screen, so that the working efficiency is influenced, the work is extremely inconvenient, and the visual experience of people watching the display material is also influenced.
In view of the above, the present invention is particularly proposed.
Disclosure of Invention
The invention aims to provide a method and a device for realizing accurate screen projection, which are characterized in that after each display screen is marked with accurate color, color shape, color number combination, color character combination and the like, a one-to-one corresponding relation is formed between the display screen in a physical environment and a controlled display screen in software, so that accurate screen projection is finally realized by distinguishing different marks of the screens, the working efficiency is improved, and the working mode is more convenient.
In order to achieve the above purpose of the present invention, the following technical solutions are adopted:
the invention provides a method for realizing accurate screen projection, which is applied to electronic display equipment and comprises the following steps:
when the electronic display device receives a content delivery instruction of a certain screen, identifying the screen and obtaining an identifier corresponding to the screen, wherein the identifier comprises any one or a combination of color identifiers, numbers and character identifiers;
and determining a display area of the screen on a display interface of the electronic display device based on the identifier corresponding to the screen, and outputting the content delivered by the screen in the display area.
Among the prior art, when carrying out a device and carrying out wired or wireless when throwing the screen to a plurality of other devices, the corresponding relation of the controlled show screen in physical environment show screen and the software takes place in disorder very easily, and the unfavorable consequence of production is that the show material can not be accurate throw the screen on the exact show screen to influenced work efficiency, it is very inconvenient to work, also influences the visual experience of watching show material people.
In order to practically solve the technical problems, the invention provides a method for realizing accurate screen projection, which utilizes a mode of adding marks on a screen, so that a one-to-one correspondence relationship can be established between a physical environment display screen and a controlled display screen in software, when display materials need to be projected, the screen to be projected can be clearly known according to corresponding mark prompts, confusion cannot occur, the working efficiency is improved, and the rapid projection of the display materials is facilitated.
In the present invention, it should be noted that, although the specific implementation manner of the mark is not limited, and may be a mark manner of numbers with different colors, characters with different colors, or a mark manner of colors, if the mark is simply made by using numbers or characters, a user in a room needs to be closer to the screen to clearly see the screen prompt characters, and correspondingly, if the marked numbers are too large, the display content may be blocked and affected by the index screen or the number, so the simple mark manner by using numbers or characters is disadvantageous.
Therefore, the invention preferably adopts a color identification mode or a mode of combining color with numbers and characters, the two modes can be adopted during actual operation, when the identification adopts a mode of combining the color identification with the numbers and the characters, the color identification mode is preferably a colored number and character identification mode, the numbers with different colors are respectively selected on each screen, and the numbers are in one-to-one correspondence with the marks of the controlled display screen on the electronic display equipment.
For convenience, the optimal mode is a mode of simply adopting color identification. It should be noted that any method that can be used to distinguish the marks by color is within the scope of the present invention.
Further, three preferable modes using color recognition are listed below.
Preferably, as a further implementable manner, the mark is a long strip-shaped color mark and is located at the upper edge of the screen, and the manner does not need any other tool, only needs to add a colored mark block with a certain shape in the display screen, and the color of the mark block is in one-to-one correspondence with the color of the mark block of the controlled display screen on the electronic display device.
Preferably, the marks are color marks, that is, the outer frame of the screen is painted with a color consistent with the color marks, and the method needs to paint a certain color on the outer frame of the screen by means of an outer tool so as to distinguish each screen, which is also most intuitive and obvious in practical application.
Preferably, the indication is a color indication, that is, a lamp with a corresponding color is installed around the screen. The mode of installing the lamp is not limited, can directly install around the screen and screen fixed connection, also can hang some fluorescent tubes, lamp area etc. around the screen, as long as can play the mode that the colour distinguishes anyhow all, the colour of installing the lamp of every screen is all different certainly, in order to be easier to discern, preferably selects some darker colours. Therefore, the mode that the indicating lamps are arranged around the screen and the outer frame is colored is adopted, the condition that the displayed content is shielded by the marks on the display screen is mainly considered, the marks on the screen can be hidden at the moment, and the light decorated beside the screen is adopted for identification.
In a word, the mode for realizing accurate screen projection has small influence on screen display materials, intuitively establishes the one-to-one correspondence between the display screen in the software and the physical environment, and practically improves the activity efficiency of the display materials.
Preferably, as a further implementable manner, the screen of the present invention may include any one of a projector, a television, a touch screen, a notebook computer, a desktop computer, and a tablet computer screen, as long as an electronic display screen capable of being used to display materials is within the scope of the present invention.
