Description
Technical field
The utility model relates to TV debugging technique, is specially a kind of online white balance debugging system.
Background technology
Whether qualified the impact of the white balance subjective effect on image be very large, for a long time, the white balance of LCD TV be all qualified by an independent prototype debug after, obtain after data in the middle of write-in program, the machine of all batches all adopts one group of identical data, but, by the selective examination to online bulk article, find that such mode cannot ensure the consistency of product white balance, colour temperature is from 10800 to 16300, gap reaches 5500K, and subjective effect difference is obvious.
Summary of the invention
In order to solve above technical problem, the utility model provides a kind of online white balance debugging system, can carry out white balance debugging online, solve the problem that white balance is consistent, guarantee that volume production product has good subjective effect the TV produced on line.
The technical scheme that the utility model adopts for technical solution problem is:
A kind of online white balance debugging system, comprising: computer; Communication switching frock, it is connected with computer, by VGA line and tested TV and communication by USB line; Color analysis device, it is provided with the probe for detecting tested TV white balance state, and its output is connected with communication switching frock; Signal generator, it is connected with computer by Serial Port Line, is connected with tested TV by HDMI wire.
As preferred embodiment, the utility model also comprises the barcode scanner for scanning bar code information on tested TV, and the output of barcode scanner is connected with computer.
The beneficial effects of the utility model are: the utility model utilizes signal generator to export testing image to tested TV, color analysis device is utilized to detect the white balance state of tested TV in real time, computer based can carry out white balance correction to TV in real time in white balance state outcome, and result is automatically stored in the white balance register of TV.As can be seen from the above description, the utility model can realize the online blank level adjustment of TV, and its system composition is simple, and correct soon corresponding, regulated efficiency is high, can meet the use of producing line.
Accompanying drawing explanation
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is the block diagram of system of the present utility model.
Symbol description: 1-computer, 2-communication switching frock, 3-color analysis device, 4-signal generator, 31-pops one's head in.
Embodiment
Debug system of the present utility model is mainly used in carrying out white balance test to TV, guarantees that every platform TV all has good subjective effect.
With reference to Fig. 1, the utility model is primarily of compositions such as computer 1, communication switching frock 2, color analysis device 3, signal generators 4.
Computer 1 is made up of main frame and display screen, is data processing terminal and the operating terminal of this debug system.Communication switching frock 2 is connected with computer 1 by USB line, and by VGA line and tested TV and communication, the signal that computer 1 is realized between tested TV by communication switching frock 2 is mutual, as arranged white balance parameter etc.
Color analysis device 3 is provided with the probe 31 for detecting tested TV white balance state, and its output is connected with communication switching frock 2, testing result is transferred on computer 1 by communication switching frock 2.Signal generator 4 is connected with computer 1 by Serial Port Line, is connected with tested TV by HDMI wire.During work, signal generator 4 shows to television transmission signal for TV under the control of computer 1.
Consider the convenience of debug process and outcome record, this debug system is preferably also provided with barcode scanner 5, and the output of this barcode scanner 5 is connected with computer 1.Tested TV can post corresponding bar code paper, computer 1 can utilize barcode scanner 5 pairs of bar code paper to scan easily, thus records the information of this TV.
During specific works, TV is connected to communication switching frock 2 respectively by VGA line, is connected with signal generator by HDMI wire, color analysis device 3 utilizes probe 31 to detect the white balance state of this TV in real time.When test starts, arrange white balance initial value, now color analysis device 3 gathers related data, judges whether white balance is applicable to, if be not suitable for, is then regulated value by computer, until the white balance value of TV meets the demands.The white balance value of now debugging directly is stored in the register of TV, for later.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
