Embodiment
Please refer to Fig. 1, it is the synoptic diagram of an embodiment of data processing module of the present invention.A specific function of data processing module 100 is that a fixing pattern (pattern) is additional in the display frame of X position pixel data of input, that is in display frame, add bright spot or the dim spot that some are specific in addition, mainly be normally to be distributed in the display frame fifty-fifty owing to noise that reasons such as quantization error cause, and the fixedly weight of pattern (weighting) that data processing module 100 is produced is greater than the weight of noise, thereby the notice of human eye vision just is subjected to these bright spots in the fixing pattern or dim spot easily and attracts and ignore the influence of noise to the picture display quality, therefore, in the present embodiment, in order to achieve the above object, data processing module 100 includes a tentation data type sample generation unit 110, one passs a look module 120 and an arithmetic element 130, wherein tentation data type sample generation unit 110 is used for producing the tentation data type sample of a preset pattern, passing look module 120 includes and passs color element 122,124, passing color element 122 passs look and handles to produce a pixel data of passing behind the look in order to the X position pixel data of input is carried out one, carry out one in order to this tentation data type sample that tentation data type sample generation unit 110 is produced and pass look and handle and pass color element 124 to produce a tentation data type sample of passing behind the look, then arithmetic element 130 is passed the pixel data that tentation data type sample behind the look and this pass behind the look according to this and is produced the staged color data of a Z position, in one embodiment, arithmetic element 130 is passed this pixel data that tentation data type sample behind look and this pass behind the look simply and is produced the staged color data of this Z position mutually, arithmetic element 130 make the staged color data of this Z position comprise the preset pattern that constitutes by bright spot, so can do in fact with a totalizer.And in another embodiment, arithmetic element 130 is passed this pixel data that tentation data type sample behind look and this pass behind the look simply and is subtracted each other to produce the staged color data of this Z position, arithmetic element 130 make the staged color data of this Z position comprise the preset pattern that constitutes by dim spot, so can do in fact with a subtracter.
Because the Z position staged color data that produced of data processing module 100 is actually and passs the pixel data that tentation data type sample behind the look and this pass behind the look by this and formed, through after the processing of display, be presented in result in the display frame and promptly be equivalence and add this preset pattern after passing look for this display frame of passing the pixel data behind the look, therefore, when the tentation data type sample that is provided when tentation data type sample generation unit 110 is fixed value, through passing passing after look is handled of color element 124 can be a fixing preset pattern, thus, data processing module 100 just can be implemented in the display frame of X position pixel data the extra additional one fixing purpose of the influence that in human eye the picture display quality caused with the reduction noise of pattern.
And keep within the acceptable range for the weight of these bright spots in the fixing pattern or dim spot, to such an extent as to do not make this fixedly pattern too obviously influence presenting of X position pixel data, the length system of the tentation data type sample that tentation data type sample generation unit 110 is produced maintains in 2, for instance, the employed tentation data type of present embodiment sample can be " 1 ", " 01 ", " 10 " or " 11 " (value of just non-0) in the fixedly bright spot of pattern or the data of dim spot position, and in that fixedly the bright spot of pattern or the data beyond the dim spot position are all 0 value.
Fig. 2 is the synoptic diagram of another embodiment of data processing module of the present invention, as shown in the figure, data processing module 200 includes a Date Conversion Unit 210, be coupled to a tentation data type sample generation unit 220 of Date Conversion Unit 210 and be coupled to one of Date Conversion Unit 210 and pass color element, wherein tentation data type sample generation unit 220 is similar to tentation data type sample generation unit 110, be used for producing the tentation data type sample of a preset pattern, Date Conversion Unit 210 then converts the X position pixel data of importing to include this tentation data type sample Y position translation data according to the tentation data type sample that tentation data type sample generation unit 220 is produced, and then passs the look processing to produce the staged color data of Z position by passing 230 pairs of Y positions of color element translation data execution one again.In one embodiment, Date Conversion Unit 210 produces this Y position translation data after this tentation data type sample being additional to one group of last position (least significant bits) of X position pixel data again, wherein, Date Conversion Unit 210 converts this X position pixel data to this Y position translation data according to comparison list (mappingtable).In another embodiment, after Date Conversion Unit 210 converted this X position pixel data to Y position mapping data earlier, the one group of last position (least significant bits) that again this tentation data type sample is additional to these Y position mapping data was to produce this Y position translation data.
Pass the display frame that the display frame of Z position staged color data after handling through display that color element 230 produced is equal to X position pixel data this moment and add fixedly pattern of this tentation data type sample pairing one.
Similarly, to such an extent as in order not make fixedly pattern used in the present invention too obviously influence presenting of display frame, the length of the tentation data type sample that tentation data type sample generation unit 220 is produced maintains in 2, in addition, in the present embodiment, because display is employed passs the color element 230 general maximum translation data that can only handle 10 bit lengths, so the selection of tentation data type sample is more with to pass color element 230 relevant.For instance, when pixel data is 8, it (is X=8 that staged color data is 6, Z=6), and passing color element 230 and be with 4 frames is that a swing circle is when passing look and handling, the length of tentation data type sample can be 1 or 2, that is tentation data type sample is in that fixedly the bright spot of pattern or the data of dim spot position can be " 1 ", " 01 ", " 10 " or " 11 ", and be all 0 value in the bright spot of fixing pattern or the data beyond the dim spot position, wherein when tentation data type sample data length is 1, Date Conversion Unit 210 is to convert 8 pixel datas to 9 translation data, and with translation data the last the position add or deduct this tentation data type sample, pass color element 230 and again 9 translation data passed the staged color data that look becomes 6; When the data length of tentation data type sample is 2, Date Conversion Unit 210 converts 8 pixel datas to 10 translation data, and with translation data the most last two add or deduct this tentation data type sample after, pass color element 230 and again these 10 translation data passed the staged color data that look becomes 6.
In the above-described embodiments, data processing module 100,200 does not limit passs employed look technology and the employed display technique of display of passing of color element, no matter which kind of coding method display uses, data processing module 100,200 all can in display frame, add one fixedly pattern to reduce the influence of noise to the picture display quality.
The above only is preferred embodiment of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
