Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention:
As depicted in figs. 1 and 2, the present invention provides a kind of image display systems comprising LED display, video camera, sameStep signal generator and video separator, the LED display, video camera electrically connect with the synchronous generator respectivelyIt connects, LED display is installed in scene, the image for playing to audience display.The video camera also with video separationDevice is electrically connected.The LED display be used for circuit sequentially play the first image, target area image and highlight image,Video camera is used to acquire the image of the first image, target area that play on LED display and highlights image and be sent to viewFrequency separator.The synchronous generator is used to control the broadcasting speed of LED display and the recorded speed of video camera, thisSample can make the broadcasting speed of LED display and the recorded speed of video camera be consistent.
When at the scene, due to human eye vision stop, when broadcasting speed quickly when, the image of target area and its highlightImage carries out overlapping to form solid background, that is to say only the first image that audience is seen.The target areaImage refer to the normal image to be seen of spectators' (such as remote living broadcast) of target area, and it highlights image and refers to thisThe image of target area highlights figure, can be handled to obtain to it by image processing software, such as PS.
The video separator by the image separation and Extraction of target area for coming out and sending to target area；DescribedOne image is the image to be seen of audience.The video separator is for coming out the image separation and Extraction of target areaAnd corresponding target area is sent to by broadcasting equipment, it that is to say that target area gets the target area by broadcasting equipmentThe image to be played, target area are played back the image of target area by playback equipment, so that it may supply the target areaPeople's viewing, play to reach different country, can see difference according to different needs with audienceContent.
Preferably, heretofore described target area can have multiple, such as when target area has 2, LED displayOn circuit sequentially play the first image, the image of target area 1, target area 1 image highlight image, target area 2Image, target area 2 image highlight image, same principle, when playing at the scene, the image and target of target area 1The image that highlights of the image in region 1 overlaps to form solid background, the image of target area 2 and highlighting for the image of target area 2Image overlaps to form solid background, and what such audience was seen is just the first image.Acquisition LED is recorded by video camera againThe image of display screen broadcasting is simultaneously sent to video separator, then passes through video separator for the image and target of target area 1The image in region 2 is distinguished separation and Extraction and is come out, and is sent on corresponding target area finally by corresponding broadcasting equipment, namelyIt is to send the image of target area 1 to target area 1, the image of target area 2 is sent to target area 2, to be formed notThe different effect of the content played with country.
The present invention also provides a kind of image display methods, are applied in above-mentioned image display system, are preferably implementedExample one includes:
S1: first frame the first image to be played is obtained, the first image is the image to be seen of audience.
S2: the second frame the second image to be played is obtained, second image is the image to be seen of target area.
S3: obtain third frame the second image to be played highlights image, and the image that highlights of the second image refers to targetThe image to be seen of region highlights image.
S4: by configuring LED display with the sequence loop play of first frame, the second frame and third frame, formed with N frame/The video that the speed of second plays.
The image that LED display plays above-mentioned three frame is controlled by logic circuit at the scene, and with first frame, the second frameWith the sequence loop play of third frame, the image played on LED display in this way just become the first image, the second image withAnd second image highlight image.In addition, it is assumed that human eye sees that normal image broadcasting speed is M frame/second, in order to enable existingThe broadcasting speed for the first image of broadcasting that field spectators are seen is M frame/second, then LED display just uses three times in the present embodimentVideo playout speed, that is to say 3M frame/second；It that is to say N=3M.For example, conventional animation play speed is 60 frames/second, thenThe broadcasting speed of LED display is set as 180 seconds/frame.Since human eye has the physiological characteristic of vision stop, it is aobvious in LEDIn the cracking situation of display screen broadcasting speed, the image that highlights of the second image and the second image that LED display is played will shapeAt solid background, the image that such audience is seen just has become first frame the first image to be played, exactly existingThe field image to be seen of spectators.
S5: recording LED display by video camera with N frame/second speed and show video, collects LED display broadcastingThe first image, the second image and the second image highlight image, and be sent to video separator.
Wherein, when LED display plays the image of above-mentioned three frame with certain broadcasting speed, by using video camera withSame recorded speed records the image played on LED display, that is to say the recorded speed and LED display of video cameraBroadcasting speed is synchronous, and video camera and LED display can be controlled by synchronous generator is played simultaneously speed.In this way,In the case where resynchronisation, so that it may accurately collect the three frame images that LED display is played using video camera, that is to say firstImage, the second image and the second image highlight image, are subsequently sent to video separator and are further processed.
S6: being separated the second image by video separator, and be sent to target area by broadcasting equipment, thusSo that target area plays the second image.
In this step, video separator receives three frame images of video camera acquisition, and separates to it, by the second figureAs separating, and corresponding target area is sent by the second image by way of broadcast, since the second image is targetThe region image to be played.It is thereby achieved that audience and remote living broadcast, due to geographical location difference and play differenceImage；That is to say audience it is seen that first frame the first image to be played, that is to say that audience to be seenThe image arrived；Remote living broadcast to be the second frame the second image to be played, that is to say what target area to be playedImage.
Such as in an Olympic tournament, the audience of the Olympic Games needs to see image A (first frame), target area 1(such as the spectators in other countries not at the scene or area) need to see that image B (the second frame), image B highlight image (theThree frames) can be by under the control of synchronous generator, loop play image A, image B and image B on LED displayHighlight image, video camera with the image played on same recorded speed admission LED display get first frame (image A),Second frame (image B) and third frame (image B's highlights image) are then passing through video separator for image A, image B, imageThe image that highlights of B separates, to get image B, finally sends target area 1 for image B and plays out.
In addition, being to play three frame images by LED display to realize the image that audience is seen in the present embodimentThe difference of the image played with target area, likewise, multiple target areas can also be adjusted simultaneously by increase and decrease frame numberPlay different images.The present invention also provides second embodiments, and under the action of resynchronizing signal generator, setting LED is aobviousFive frame image of display screen loop play, first frame are the first image to be seen of audience, and the second frame is wanted by target area 1The second image seen, the second image to be seen of third frame target area 1 highlight image, and the 4th frame is target area 2The third image to be seen, the third image to be seen of the 5th frame target area 2 highlight image；Then it is shown in LEDShield last five frame image of loop play, and its broadcasting speed is reached into the broadcasting speed that people normally watch video cartoonFive times, for example the conventional animation play speed being previously mentioned in the present embodiment is 60 frames/second, then sets 300 for its broadcasting speedFrame/second is also in this way the first image that first frame is played when audience passes through the image that LED display is seen, becauseThe image that highlights for the second image and the second image forms solid background in human eye, and the reversion of third image and third image is slowSlowly solid background is formd in human eye.
Then the image on LED display is recorded with identical recorded speed by video camera again, in the control of synchronizing deviceUnder system, collect above-mentioned five frames image, then by video separator respectively go out the second image to be played of target area 1 withAnd the target area third image to be played, and mesh is sent by the second image, third image respectively by way of broadcastRegion 1, target area 2 are marked, sees the first image so as to complete spectators at the scene, the second image, target are seen in target area 1Third image is seen in region 2, realizes the demand that different countries plays different images.
Preferably, when the number difference of target area, in order to guarantee that the broadcasting speed of picture that human eye is seen is keptUnder normal conditions, then the broadcasting speed of LED display can also adjust accordingly, it is assumed that the broadcasting for the picture that human eye is seenSpeed is conventional broadcasting speed, then as when target area has 1, then the broadcasting speed of LED display is set in above-described embodiment one3 times of conventional animation play are set to, when target area is 2, then the broadcasting speed of LED display is set to conventional animation5 times played, the broadcasting speed for the picture that such human eye is seen remains as the broadcasting speed of conventional animation, simultaneous cameraAlso the broadcasting speed of moment and LED display is consistent recorded speed.It that is to say, when target area is N number of, then LED is aobviousThe broadcasting speed of display screen is set to 2N+1 times of conventional animation play.Due to target area have it is multiple, then it is corresponding broadcast setIt is multiple for also having, than as shown in Figure 1.
Therefore, realize that different or area plays the demand of different images through the invention, the invention is simple on image procossingList, processing speed are fast, do not need as requiring a great deal of time in the prior art the later period gone with energy to video sourceIt is handled.In addition, realizing that similar technical solution also belongs to this hair by the broadcasting speed of increase and decrease frame number or change frameBright claimed technical solution.
It will be apparent to those skilled in the art that can make various other according to the above description of the technical scheme and ideasCorresponding change and deformation, and all these changes and deformation all should belong to the protection scope of the claims in the present inventionWithin.
