Description
Technical field
The utility model relates to the system of a kind of compensation LED display image distortion.
Background technology
The use occasion of LED display more and more widely relates to square, station, court, market, bank or the like.Because LED display has high brightness, with its as advertising carrier appear at the public arena be a kind of popularize the fastest application mode, most typical is exactly to be applied in the physical culture competition field.Place LED display as football field, basketball court, table tennis court, tennis court or the like around in competition area, spectators have just seen the advertising image on the LED display naturally when coming to matches, moreover some important matches also television relay even live can occur, the athletic while on the live camera lens aiming court, the advertising image on the LED display is also relayed as athletic background or is live.
The mode of this playing advertisements has both merits and demerits: advantage is this mode playing advertisements efficient height, with strong points, the people of match of having a passionate love for sports likes the in-situ match grand occasion of coming to matches, simultaneously their articles for use that equally also have a passionate love for sports are play the sports goods advertisement and often can be played a multiplier effect in face of the consumer of these articles for use that have a passionate love for sports; Shortcoming is that the reproduction time section of this series advertisements is bundled by fixture fully, sports tournament begins advertising image and just begins to play, in a single day match finishes spectators and leaves the theatre, advertisement just continues the meaning of broadcast, all court screens must stably be worked during limited sports tournament, in case image fault appears in court screen picture, want to allow match stop to wait and fixed the court and shield when playing again impossible, and allow maintenance personal's on-site maintenance also can delay reproduction time, so, the chance that the valuable playing advertisements of waste will appear in flopover in case take place in all court screens.
The utility model content
The technical matters that the utility model mainly solves provides the system of a kind of compensation LED display image distortion, can guarantee the display quality of LED display picture, the while can not influence its work and carry out flopover and handle when the LED display picture breaks down.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the system of a kind of compensation LED display image distortion is provided, comprises that the image that is used to read from LED display output picture reads the display unit that is written into unit, system backstage and the LED display that is connected with the compensating unit output terminal.
Wherein, described image detecting element comprises and is used to read the standard output image and image reads the comparing unit of the feature difference between the image that is written into the unit input, and the operation processing unit that produces the compensated information of the described feature difference of compensation.
Wherein, described image reads and is written into the unit and comprises ccd image sensor.
Wherein, the system of described compensation LED display image distortion comprises that module test section, casing test section, region detecting part are divided and whole screen test section, and described each test section all has described image and reads and be written into unit, image detecting element, compensating unit.
The beneficial effects of the utility model are: the LED display picture that is different from prior art breaks down can't in time repair the situation of recovery as the display frame distortion, the utility model is by being provided with the system of a compensation LED display image distortion, be written into the unit and read image information by reading from LED display output, and the image information that reads detected the output compensated information through image detecting element, compensating unit detects the distortion of the compensated information output image of output according to image detecting element, and will recover the display unit demonstration that the picture signal after the distortion is exported to LED display, thereby do not need in the process of entire process fault to allow LED display quit work, and can guarantee the quality of LED display display frame constantly.

Embodiment
By describing technology contents of the present utility model, structural attitude in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 1, the system of the utility model compensation LED display image distortion, comprise the module test section, the casing test section, region detecting part is divided and whole screen test section, and described each test section all has to be used to read read from the image of LED display 40 output pictures and is written into unit 10, read with described image and to be written into the image detecting element 20 that is used to produce compensated information that unit 10 output terminals are connected, what be connected with image detecting element 20 output terminals compensates the compensating unit 30 of output image distortion and the display unit of the LED display 40 that is connected with the compensating unit output terminal according to described compensated information.
Image reads and is written into unit 10 and reads from the image information of LED display 40 output, in the present embodiment, described image reads and is written into unit 10 and can reads from the image information of LED display 40 output for ccd image sensor or such as the image of camera fetch equipment.The picture that play LED display in the dead ahead that CCD is positioned at LED display display frame detects, and the picture signal that detection is read is transferred to image detecting element 20 handles.
Described image detecting element 20 comprises comparing unit 21 and operation processing unit 22, and it is poor that described comparing unit 21 is used to read the feature that standard output image and image read between the image that is written into unit 10 inputs; Described operation processing unit 22 produces the compensated information of the described feature difference of compensation according to the feature difference of comparing unit 21 outputs, and exports compensated information and give compensating unit.For example, the level difference between the image information of the display unit input of the comparing unit 21 comparison LED display 40 of image detecting element 20 and the output image information of standard is created the compensated information that compensates the output characteristic difference then.
The distortion of the compensated information compensation output image that described compensating unit 30 is used for being produced according to described image detecting element 20, and will recover the display unit that picture signal after the distortion is exported to LED display 40.
