For allowing the auditor can more understand technology contents of the present invention, be described as follows especially exemplified by going out preferred embodiment.
Below please refer to Fig. 1, Fig. 1 is the system block diagram of signal processing system 1 of the present invention.As shown in Figure 1, signal processing system 1 of the present invention comprises signal source 10 and display device 20, and signal source 10 is electrically connected by signal transmssion line 30 with display device 20, in order to the data transmission medium between conduct both.In the present embodiment, signal source 10 is a main frame, and display device 20 can be a computer screen, a televisor or a projector, but aforementioned signal source 10 or display device 20 also can select other electronic installations with similar functions to replace, and are not limited with the present embodiment.In addition, basis signal source 10 is different from the signal specification that display device 20 adopts, and signal transmssion line 30 can corresponding be selected the circuit of a VGA signal wire, a DVI signal wire, a HDMI signal wire or other specifications.
In order to make signal processing system 1 of the present invention can reach the bidirectional data transfers effect of 20 of signal source 10 and display device, signal processing system 1 of the present invention is supported the technology of DDC, signal transmssion line 30 and communication protocol by corresponding DDC 40, so that 20 of signal source 10 and display device are carried out bidirectional data transfers, but the present invention is as limit, and any similar techniques of the bidirectional data transfers of 20 of signal source 10 and display device that can provide all can be applicable to the present invention.
Signal source 10 comprises signal processing module 11, in order to transmission and the processing of carrying out signal or data.Design by aforementioned DDC 40, make signal processing module 11 to obtain an Identification Data from display device 20 by DDC 40, in the present embodiment, Identification Data can be extending display identification data, and it comprises the parameters such as the product related information of corresponding display device 20, the displaying ratio of supporting, resolution, display frequency.Then, the signal output specification that the display device 20 that signal processing module 11 is confirmed to have connected according to Identification Data is supported produces corresponding display to select suitable signal parameter, is shown for exporting display device 20 to.This moment, signal processing module 11 can be obtained a sequential format information of the corresponding display that produces, it mainly comprises the parameter values (such as 1024x768 70Hz or 800x600 75Hz etc.) such as the resolution of display output and display frequency, because these parameter values are that signal source 10 decision displays are exported the formula that really fixes, so sequential format information can be used as the sequential format comparison basis of display.In the present embodiment, signal processing module 11 can comprise an application program, determine the sequential format information of corresponding display output in order to the foundation Identification Data, obtain the sequential format information of the corresponding display that produces and be sent to display device 20, but also can adopt hardware or other modes to carry out similar action, the present invention is not as limit.
Display device 20 comprises receiver module 21, storage module 22 and processing module 23, and receiver module 21 is in order to receive the display from signal source 10; Storage module 22 is obtained by DDC 40 for signal source 10 in order to store aforesaid extending display identification data, and storage module 22 can be a storer in the present embodiment.Processing module 23 can be carried out sample of signal to the display that receives according to a sampling setting value, and carry out sequential for the signal after sampling and detect, to judge that the corresponding sequential format of present display is shown, this sample of signal and sequential detection mode are known technical characterictic, do not add to give unnecessary details at this.And in signal processing system 1 of the present invention, processing module 23 also is received in the obtained sequential format information of signal source 10 by DDC 40, with the sequential format comparison basis as display.Therefore, signal processing system 1 of the present invention will respectively obtain by aforementioned two kinds of different approaches a kind of judged result of sequential format corresponding to same display.
By processing module 23, itself is carried out for display the result that sequential detects, and compared from the sequential format information of this obtained display of signal source 10, judge whether both are consistent, with the sequential format that determines to show that display was used.Under normal condition, for same display, the result that its sequential detects should conform to sequential format information, namely is illustrated in signal source 10 and which kind of sequential format produces display with, just shows this display with this kind sequential format in display device 20.When the result that detects when aforementioned sequential was consistent with sequential format information, the sequential that expression processing module 23 is carried out for display detected errorless, so can directly adopt measured sequential format correctly display to be shown.The result that detects when aforementioned sequential and sequential format information are not simultaneously, represent the possibility of result that sequential detects because the display quality is not good or other problems and cause and can't correctly detect, therefore processing module 23 will be done further judgement for display and process, to determine that the sequential format of suitable display shows.
When the sequential format of display is some specific time sequence, easily cause processing module 23 to detect obscuring and be difficult to clearly distinguish in judgement in sequential, for example the sequential format of signal source 10 display that determines is 1440x900 originally, carrying out to think it by mistake 1600x900 after sequential detects through the processing module 23 of display device 20, thereby form the result situation different from sequential format information that aforementioned sequential detects, and this class sequential format namely is defined as the fuzzy time series form.Wherein the fuzzy time series form can comprise 1440x900 and 1600x900,1680x1050 and 1400x1050 or 1366x768 and 1024x768 etc.The result that detects for the sequential that erroneous judgement causes of avoiding this type is different from sequential format information, and whether the result that therefore will further judge measured sequential detection by processing module 23 corresponding aforementioned fuzzy time series form.
In the present embodiment, deposit the related data of the fuzzy time series form that this class is difficult to clearly distinguish in the storage module 22 of display device 20, so that processing module 23 is as the basis for estimation of sequential format, but its embodiment is not limited with the present embodiment.The result that detects when sequential and sequential format information are not simultaneously, processing module 23 can be compared present the sequential result that detects and the related data that is stored in the fuzzy time series form in storage module 22, to judge whether corresponding aforementioned arbitrary fuzzy time series form of result that present sequential detects.If the result that sequential detects belongs to this type of fuzzy time series form, can learn it is to judge by accident because the sequential of processing module 23 detects, the result that makes sequential detect is different from sequential format information, and this moment, processing module 23 can adopt sequential format information as the correct sequential format that shows present display.If the result that sequential detects not is during for this type of fuzzy time series form, namely get rid of the situation of the aforementioned erroneous judgement of this type, so processing module 23 will do further judgement for display and process, to determine that the sequential format of suitable display shows.
If the not corresponding aforementioned arbitrary fuzzy time series form of result that sequential detects, represent that processing module 23 may be because the quality of display own be not good or other reasons, make a mistake and cause sequential to detect, the result that makes sequential detect is different from sequential format information, therefore by design of the present invention, display is resampled to carry out a new sequential and detects.Processing module 23 is set by upgrading sample of signal originally, to resample for display.Wherein processing module 23 is that benchmark comes the update signal sampling to set according to acquired sequential format information, obtains an optimized sampling result with expectation by new setting, then it is carried out new sequential detect.
After the 23 pairs of displays of processing module are carried out new sequential and are detected, processing module 23 will be again with aforementioned acquired sequential format information as benchmark, whether consistent with sequential format information in order to compare the result that new sequential detects.When aforementioned both when consistent, represent that namely new sequential detects errorless, so display device 20 can adopt directly new sequential to detect measured sequential format correctly to show this display.If the result that new sequential detects is still different from sequential format information, represent may display not good or hardware signal processing system 1 of the signal quality problem such as break down own, this moment, processing module 23 will with sequential format information as present sequential format corresponding to display, be shown for display device 20.
therefore, signal processing system of the present invention 1 utilizes sequential format information such as resolution at signal source 10 display that determines as comparison basis, itself compare for the measured sequential format of display with display device 20, action is processed in the judgement that is aided with other, judge that sequential format information that sequential testing result or signal source 10 with display device 20 determined is as the sequential format of display, correctness with the sequential specification of guaranteeing display device 20 display that adopted, avoid the wrong sequential specification judgement of display generation is caused the problem in the signal demonstration.
Please refer to Fig. 2, Fig. 2 is the process flow diagram of signal processing method of the present invention.It is noted that, though below as an example of signal processing system shown in Figure 11 example the explanation signal processing method of the present invention, but the present invention is not limited to be applicable to signal processing system 1, and any other signal processing system with similar framework is applicable signal processing method of the present invention also.As shown in Figure 2, signal processing method of the present invention comprises that step S1 is to step S6.Below will describe each step of signal processing method of the present invention in detail.
Step S1: receive from a display of signal source 10 and a sequential format information of corresponding display in display device 20.Signal processing system 1 of the present invention is supported DDC, and signal source 10 utilizes signal transmssion line 30 to be electrically connected with display device 20.The signal processing module 11 of signal source 10 can first be obtained the extending display identification data by DDC from display device 20, determines that according to the extending display identification data sequential format information of signal output is to produce corresponding display.The receiver module 21 of display device 20 can pass through the display that signal transmssion line 30 receives from signal source 10 afterwards, and processing module 23 can receive sequential format information by DDC.
Step S2: carry out a sequential for display and detect.Display device 20 is after receiving display, and processing module 23 can be carried out sample of signal to display according to the default sampling setting value of device, and carries out sequential for the signal after sampling and detect, why to judge the corresponding sequential format of present display.
Step S3: whether the result that the comparison sequential detects is consistent with sequential format information.As benchmark, processing module 23 is compared result and sequential format information that sequential detects mutually, judges whether both are consistent by the obtained sequential format information of abovementioned steps S1, with the decision sequential format that display was used.For instance, suppose that signal source 10 determines that the sequential format of signals output is 1024x768, and with this information as sequential format information to be sent to display device 20; When processing module 23 judges that by the sequential detection sequential format of display also is 1024x768, the result that detects through the contrast judgement sequential is consistent with sequential format information, the sequential detection that namely represents processing module 23 is errorless, so display device 20 can directly adopt measured sequential format (being 1024x768) correctly to show this display.And the sequential format that detects the judgement display when processing module 23 by sequential is when being sequential format beyond 1024x768, the result that detects through the contrast judgement sequential is different from sequential format information, the sequential detection that may represent processing module 23 makes a mistake or is affected by other factors, therefore will do further judgement for display and process, to determine that the sequential format of suitable display shows.
Step S4: judge a whether corresponding fuzzy time series form of result that sequential detects.Wherein to be display device 20 easily obscure in judgement the fuzzy time series form and the sequential format that can't clearly distinguish, such as 1440x900 and 1600x900,1680x1050 and 1400x1050 or 1366x768 and 1024x768 etc.When the corresponding aforementioned arbitrary fuzzy time series form of result that the judgement sequential detects (take 1366x768 and this group of 1024x768 as example, suppose that the result that sequential detects is 1366x768, and sequential format information is 1024x768), represent that processing module 23 fails to detect by sequential the sequential format of clear judgement display, so processing module 23 will adopt obtained sequential format information as present sequential format (being 1024x768) corresponding to display; But (same precedent when the result of judgement sequential detection is not above-mentioned arbitrary fuzzy time series form, suppose that the result that sequential detects is 1280x768, and sequential format information is 1024x768), get rid of sequential and detect situation about judging by accident because running into the fuzzy time series form, therefore will proceed other judgements and process.
Step S5: resample by upgrading a sampling of display is set, detect to carry out a new sequential.For example sequential format information is 1024x768, and processing module 23 is namely upgraded its sample of signal setting according to the sequential specification of 1024x768, and sets for display according to the sample of signal after upgrading and take a sample to carry out new sequential detection.
Step S6: whether the result of comparing new sequential detection is consistent with sequential format information.The sequential format information of supposing to obtain display is 1024x768, after carrying out the optimal setting of aforementioned corresponding sequential format information for display in theory and carry out new sequential detecting, the result that this new sequential detects should be consistent with sequential format information, the present sequential format corresponding to display of result conduct that so just can adopt new sequential to detect.If the result that new sequential detects is still different from sequential format information, this moment, processing module 23 will be take sequential format information as main, as sequential format corresponding to present display.
To sum up institute is old, and no matter the present invention everywhere all shows it totally different in the feature of known technology with regard to purpose, means and effect, is a quantum jump, earnestly asks the auditor to perceive, and grants early quasi patent, makes Jiahui society, and the true feeling moral just.Only must note, above-described embodiment is only exemplary illustration principle of the present invention and effect thereof, but not is used for limiting the scope of the invention.Any those skilled in the art all can under know-why of the present invention and spirit, make an amendment and change embodiment.The scope of the present invention should be as described the scope of claims described.
