Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
An object of the embodiments of the present invention is to provide a method, an apparatus, and a system for displaying on a screen, so that the viewing effect of a user can be effectively improved at a low cost, and thus a stronger sensory impact can be excited, and viewers can be made to look after the screen is viewed. And moreover, a high-quality viewing environment atmosphere can be provided, so that audiences can exert better mental ability, can concentrate on mental activities more easily, create more relaxed picture viewing experience, relieve the mind and body and substitute pictures more easily. The invention will be further explained with reference to the drawings.
The first embodiment is as follows:
fig. 1 shows an implementation process of a screen display method provided by a first embodiment of the present invention, where LED lamp sets are disposed at edges of the screen, and the method is detailed as follows:
in step S101, color information of edge pixels of a video play screen is acquired in real time.
Specifically, the video playing picture refers to a video picture played by a video player. For the television program picture, the video program content output by the set-top box or other television boxes can be used. For other video program contents, the video contents played by a player such as a computer or a tablet computer can be used.
The number of the edge pixels and the size of the area can be flexibly selected according to different types of players playing videos. For example, for a player with a smaller resolution, a smaller number of pixels may be selected as edge pixels, such as selecting a row or a column of pixels closest to the edge, or selecting two rows or two columns of pixels closest to the edge, or three rows or three columns of pixels, etc. For a player with a larger resolution, such as a currently used high-definition 4K television player, a larger number of pixels may be selected as edge pixels. Such as selecting the ten rows or columns of pixels closest to the edge, etc.
The color information may be represented by a three-primary color representation method, such as recording a color value of each of the three primary colors, and representing the color information of the pixel point by the recorded color value. Of course, it is not limited to the three primary colors, and may include other color information such as brightness and the like.
In the embodiment of the present invention, the step of acquiring color information of edge pixels of a video playing picture in real time specifically includes:
the video input end of a video line which is divided into two parts is connected with a video source, the first output end of the video line is connected with a display device, and the color information of the edge pixel of a playing picture is obtained by analyzing the video signal output by the second output end of the video line.
The video source can be a television box, a set-top box, a computer or a tablet computer and the like. And a video line divided into two is selected, so that the content displayed on the screen can be synchronous with the LED lamp group displayed after the color content of the pixel is analyzed. Certainly, the video cable divided into two can be HDMI, VGA or DVI video cable divided into two according to the requirement.
Of course, the video content may also be transmitted in a wireless connection manner, and when the player receives the picture content wirelessly or by wire, the pixel analysis device may also receive the currently played picture to perform synchronous analysis.
In step S102, according to the color information of the edge pixel, the LED lamp set corresponding to the position of the edge pixel is controlled in real time to display corresponding color information.
Specifically, the LED lamp sets are selected according to the size of the display screen and the strength of the display effect, and the LED lamp sets can be light-emitting modules formed by three primary color LEDs, and the light-emitting intensity of the three primary color LEDs can be adjusted, so that the display of emitting different colors can be realized. The LED lamp sets can be arranged on the periphery of the display screen at equal intervals, or on one or more sides of the display screen. The display screen can be a television, a wall surface for projection display and the like.
The corresponding relation between the LED lamp groups and the pixels can allocate corresponding pixel areas according to the distributed LED lamp groups. If the resolution of the screen is a, b, if the coordinates of the upper left corner are set to (1,1) and the coordinates of the lower right corner are set to (a, b), if a row closest to the edge and a column of pixels are selected as edge pixels, then the coordinates of each pixel point at the edge pixels are determined. For example, the coordinate of the pixel at the upper right corner is (a,1), and the coordinate at the lower left corner is (1, b), and the coordinate or the set of coordinates of the pixel point corresponding to the LED light group can be recorded and stored according to the distribution position of the LED light group.
In the embodiment of the present invention, the step of controlling the LED lamp group corresponding to the position of the edge pixel to display the corresponding color information according to the color information of the edge pixel specifically includes:
calculating average color information of pixel areas corresponding to the LED lamp groups according to a preset corresponding relation between the LED lamp groups and the pixel areas;
and controlling the corresponding LED lamp group to display according to the average color information.
The average color information of the calculation pixel region may be average color information of three primary colors of each pixel of the calculation pixel region, such as average color information of red, average color information of green, and average color information of blue, and the light emission intensity of the LED lamps in the corresponding LED lamp group is controlled according to the calculated average color information. For example, a value of average color information of red is calculated, and the luminous intensity of the red LED is correspondingly controlled.
According to the invention, the LED lamp groups are arranged at the edge of the screen, the color information of the edge pixel of the currently played video picture is acquired in real time, and the LED lamp groups corresponding to the edge pixel are correspondingly controlled according to the color information of the edge pixel, so that the LED lamp groups emit corresponding colors, and therefore, the LED lamp groups can display the colors related to the content played by the current screen in a larger area, and the viewing effect is obviously improved through lower cost.
Example two:
fig. 2 shows an implementation flow of the screen display method provided by the second embodiment of the present invention, which is detailed as follows:
in step S201, color information of edge pixels of a video play screen is acquired in real time.
In step S202, according to the color information of the edge pixel, the LED lamp set corresponding to the position of the edge pixel is controlled in real time to display the corresponding color information.
Steps S201 to S202 are substantially the same as steps S101 to S102 in the first embodiment, and are not repeated herein.
In step S203, when it is detected that the video playing is finished, the corresponding LED lamp set is controlled to display the corresponding color information according to the color information of the edge pixel of the picture where the playing is finished within a first predetermined time range.
The detection of the end of video playing can be judged by detecting whether the video content changes. For example, when the time for judging that the content of the video picture is still exceeds a certain time, for example, exceeds 5 seconds, it is judged that the current video playing is finished. Or the playing progress information of the video can be acquired from the player, and whether the playing of the current video is finished or not is judged according to the playing progress.
The first preset time range can be 5 minutes or 3 minutes and the like, and is used for providing high-quality viewing environment atmosphere after a screen picture is watched, enabling audiences to exert better mental capacity, being more easy to concentrate on mental activities, creating more relaxed picture watching experience, relieving the mind and body, and enabling the audiences to substitute the picture more easily. And when the first preset time range is exceeded, the display of the LED lamp group is turned off.
On the basis of the first embodiment, the embodiment of the invention further expands the screen display after the video content is played, so that the user can obtain better user experience after the user finishes watching the video.
