Description
Technical field
The invention relates to the technology of plasma panel, especially, reduced storer and used proportion, the image processing arrangement of a kind of plasma panel of raising image processing efficient and the invention of method about having improved the method for distinguishing static images and dynamic image.
Background technology
The common plasma panel next door between substrate and the back substrate in front is a unit, is filled with the main discharge gas of neon (Neon), helium (helium) or neon, helium gas mixture body in each unit and contains the inert gas of a spot of xenon.When relying on the HF voltage discharge, inert gas produces vacuum ultraviolet (VacuumUltraviolet rays) makes the luminophor between the next door luminous, thereby demonstrates portrait.Such plasma panel can be made thinlyyer and be light, becomes display device of new generation of greatest concern at present.
Fig. 1 is the structural representation of common plasma panel.As shown in Figure 1, plasma panel is by 110 one-tenth certain distances of front substrate 100 and back substrate be combined into that is arranged in parallel.Arranging on the front substrate 100 mounted in pairs in front on the glass 101 scan electrode 102 and keep electrode 103 several keep electrode, arranging on the back substrate 110 with several of the arrangement of front substrate 100 and keeping several address electrodes 113 that electrode pair intersects.
In the discharge cell of front substrate 100 by mutual discharge keep the unit luminous scan electrode 102 and keep electrode 103, i.e. transparency electrode a that makes by transparent ITO material and the scan electrode 102 that constitutes by the bus electrode b that metal electrode is made and keep electrode and constitute in pairs.Scan electrode 102 and keep electrode 103 restriction discharge currents, and above be covered with the insulation that the above insulation course of one deck 104 keeps between electrode pairs, on upper insulation layer 104, be added with magnesian protective seam 105 above the discharging condition in order to satisfy.
Back substrate 110 is being arranged several discharge spaces, promptly in order to form striped type (or the well type) next door that the discharge cell keeping parallelism is arranged.The executive address discharging function produces the ultrared majority of a vacuum address electrode 113 and is installed in parallel on the next door.The upper side of back substrate 110 shows the R of the visible light of portrait, G, B fluorophor 114 when scribbling the discharge of radiation address.The lower insulation layer 115 that protection address electrode 113 is arranged between address electrode 113 and the fluorophor 114.
Fig. 2 is the portrait gray scale technique of expression synoptic diagram of traditional plasma panel.
As shown in Figure 2, the portrait gray scale of traditional plasma panel (Gray Level) method for expressing is that frame one by one is divided into a plurality of luminous time different subdomains of number, each subdomain is further divided into reset the time (RPD) of all unit of initialization, selects the address time (APD) of discharge cell to reach hold time (SPD) that realizes gray scale by the number that discharges back.For example, show portrait if want with 256 gray scales, the frame time (16ms) that then is equivalent to 1/60 second is divided into 8 subdomains (SF1 is to SF8) as shown in Figure 2, and 8 subdomains (SF1 is to SF8) are further divided into the time of reseting (RPD), address time (APD) and hold time (SPD).
Reset the time (RPD) of each subdomain all is identical with the address time (APD).Select the address discharge of the unit that discharges to rely on the voltage difference between address electrode and the scan electrode to form.Hold time in each subdomain with 2
n(n=0,1,2,3,4,5,6,7) ratio increases.Therefore, because the difference of holding time in each subdomain, so can be by regulating holding time of each subdomain, the number that returns of promptly keeping discharge comes representing gradation.
Rely on above-mentioned way to realize several frames.If rely in the frame that above-mentioned way realizes a frame identical with the image data value of next frame, be rest image then, be dynamic image if the data value of a frame and next frame are inequality.So the low problem of certain image frame quality can appear in the method for difference rest image and dynamic image.For example, when with Same Way rest image and dynamic image being handled, dynamic image can be handled very clearly, but rest image is owing to noise causes image quality low.
Therefore, dynamic image and rest image generally adopt different disposal routes in the plasma panel, improve the quality of picture.
In order to use different image treatment methods static images and dynamic image are handled and static images and dynamic image strictly need be distinguished.The traditional static images and the differentiating method of dynamic image are that the image data value with the image data value of previous frame and present frame compares, then whether the difference of the data value of the image data value of former frame and present frame is judged within the reference value of having reserved, thereby distinguished static images or dynamic image.
Fig. 3 is traditional image treatment method key diagram.
As shown in Figure 3, traditional image treatment method is at first selected a certain size several zones (a, b, c on the display surface 300 of plasma panel, d, e, f, g, h i), differentiates the image data value of a frame in several selected zones, is stored in certain storer (not shown).
Then, if imported the image data of next frame, then select several zones (a, b with the front, c, d, e, f, g, h, i) zone of corresponding plasma panel 300 (A, B, C, D, E, F, G, H, I), differentiate the image data value of a frame in several selected zones, the image data value of differentiating is compared, see whether the result of comparison is identical.The image data value in B zone and the image data value in b zone compare, and whether discriminant value is identical.The image data value in judgement C zone and the image data value in c zone use the same method, the image data value in D zone and the image data value in d zone, the image data value in E zone and the image data value in e zone, the image data value in F zone and the image data value in f zone, the image data value in G zone and the image data value in g zone, the image data value in H zone and the image data value in h zone, whether the image data value in I zone is identical with the image data value in i zone.Though the a-quadrant is set at different values with a zone here, do not show in the drawings, in fact the a-quadrant is the identical zone of value with a zone.
Whether each regional image data value in several zones on the article on plasma display screen 300 is identical as mentioned above when differentiating, each red (R) for example by each zone is comprised, green (G), each R between blue or green (B) discharge cell, G, whether B image data value is identical differentiates, thereby can judge whether each zone is identical.
As mentioned above, to whether each regional data value identical differentiate after, compare with the reference value of having reserved, judge that present frame is dynamic image or static images.For example suppose above-mentioned reference value is set at 2 data value differences of permission, if the image data value in the image data value of a-quadrant and a zone, the image data value in B zone and the image data in b zone, the image data value in C zone and the image data value in c zone, the image data value in D zone and the image data value in d zone, the image data value in E zone and the image data value in e zone, the image data value in F zone and the image data value in f zone, the image data value in G zone and the image data value in g zone, the image data value in H zone is all identical with the image data value in h zone, has only the image data value in the image data value in I zone and i zone inequality.Be the conclusion of static images so with regard to the image that draws present frame.If the image data value in the image data value of a-quadrant and a zone, the image data value in B zone and the image data in b zone, the image data value in C zone and the image data value in c zone, the image data value in D zone and the image data value in d zone, the image data value in E zone and the image data value in e zone, the image data value in F zone and the image data value in f zone, the image data value in G zone is identical with the image data value in g zone, and the image data value in the image data value in H zone and h zone, the image data value in I zone and the image data value in i zone are inequality.Be the conclusion of dynamic image so with regard to the image that draws present frame.
But when stating image treatment method in the use, all image data values in each zone all must be stored in the storer (not shown).For example, after the regional image data value of each of previous frame all is stored in the storer (not shown), when the image data of next frame is imported, each the regional image data value that is stored in the previous frame of storer (not shown) to be read, compare with the image data value of present frame, judge whether each regional image data value is identical.Therefore, will increase the resource of image data value in order to distinguish static images or dynamic image, i.e. proportion in the storer (not shown) at plasma panel.If image data value relatively rolls up, just may need to increase an external memory storage (not shown).
Therefore, the image treatment method of traditional plasma panel in order to distinguish static images and dynamic image, can increase the proportion of the shared storer of image data, reduces the efficient that overall image is handled.

Embodiment
Image processing arrangement and method embodiment to plasma panel of the present invention is elaborated below with reference to accompanying drawings.
Fig. 4 is the image processing arrangement synoptic diagram according to plasma panel of the present invention.
As shown in Figure 4, the image processing arrangement according to plasma display panel of the present invention moves test section (Motion Detection) 400 by image, portrait handling part 401, compositions such as deposited obedient portion 402 of subdomain and data sorting portion 403.
Image moves test section 400 by handling the means (not shown) by specific signal, for example by from VSC (Video Signal Controller) chip, import image data detect motion, be that static images or dynamic image are judged to current frame.Image moves the internal storage (symbol is not specified) of cyclic redundancy check (CRC) (Cyclic Redundancy Check is hereinafter to be referred as the CRC) value of the image data that each frame of storage is preferably arranged in the test section 400.
The image data that subdomain applies 402 pairs of portraits handling part, 401 processing of obedient portion carries out the deposited card of subdomain.
The Cyclic Redundancy Check value that image moves the image data of the Cyclic Redundancy Check value of image data of 400 pairs of former frame of test section and current frame compares, whether the difference of Cyclic Redundancy Check value of image data of judging the Cyclic Redundancy Check value of image data of former frame and present frame is within the reference value of having reserved, and distinguishing then is dynamic image or static images.The Cyclic Redundancy Check method is the mode for the use Hue binit that detects the mistake that produces in the data transfer procedure.In detail, if being exactly the data that will transmit side, the Cyclic Redundancy Check method is divided into piece, transmit after pasting the circular symbol that upward relies on the polynomial special computing of scale-of-two to obtain behind each piece, receiver side also relies on same computing so, by judging whether to have obtained identical circular symbol in the method that detects the transmission mistake that whether takes place.The Cyclic Redundancy Check method has very strong error detection capability.The Cyclic Redundancy Check method is used in the Cyclic Redundancy Check value of obtaining each image data on each image data.
The Cyclic Redundancy Check method comprises Cyclic Redundancy Check 8, Cyclic Redundancy Check 16, Cyclic Redundancy Check 32 etc.The polynomial expression that uses in the Cyclic Redundancy Check 8 is as follows:
[mathematical formulae 1]
X
8+X
5+X
4+1
The polynomial expression that uses in the Cyclic Redundancy Check 16 is as follows:
[mathematical formulae 2]
X
16+X
15+X
2+1
Utilizing the Cyclic Redundancy Check operation method to obtain the Cyclic Redundancy Check value of image data, the Cyclic Redundancy Check value obtained also present frame and former frame are compared, is that dynamic image or static images are judged to current frame.Under Cyclic Redundancy Check 16 operation method situations, the error of its Cyclic Redundancy Check value is 1/2
16So, can be through fully to trusting because error is very little.
Utilize the Cyclic Redundancy Check operation method to detect motion, the image of promptly distinguishing static images and still be dynamic image move 400 pairs of current frames of test section be the method judged of static images or dynamic image as shown in Figure 5.Here as shown in Figure 3, as shown in Figure 3, though the a-quadrant is set at different values with a zone, in fact the a-quadrant is the identical zone of value with a zone.
As shown in Figure 5, image among Fig. 4 moves a certain size several the regional a on the display surface 500 of 400 pairs of optional plasma panels of test section, b, c, d, e, f, g, h, the image data value of the discharge cell (not shown) that comprises in each zone in the I is carried out the Cyclic Redundancy Check computing, obtains specific Cyclic Redundancy Check value.4 discharge cells in the discharge cell of here supposing plasma panel is comprised combine as a zone, promptly suppose each the zone in discharge cell be 4 after, carry out the Cyclic Redundancy Check computing.The Cyclic Redundancy Check value of each discharge cell corresponding image data that will obtain is then all added up, and obtains the Cyclic Redundancy Check value in a zone.The image data value is the data of certain byte, and for example the data of 8 bytes are comprising the image information of importing in each discharge cell of plasma panel.Above-mentioned image data is carried out computing.
Several zones of on the utilization said method article on plasma display screen display surface 500 a certain size, a for example, b, c, d, e, f, g, h, the regional value of each of I is carried out computing, obtains the Cyclic Redundancy Check value.Then the Cyclic Redundancy Check value of obtaining is stored in certain internal storage (not shown).The Cyclic Redundancy Check value of at this moment storing in the storer is the Cyclic Redundancy Check value of the image data of former frame.And the Cyclic Redundancy Check value of storing in the storer is the Cyclic Redundancy Check value in the certain zone on the plasma panel display surface 500, is the data of 16 bytes under Cyclic Redundancy Check 16 situations.The ratio that takies of its storer is reduced greatly than traditional image treatment method as a result.It is original littler also harmless that image moves the volume ratio of the internal storage that comprises in the test section 400 like this.
Then, if imported the image data of next frame, then select each zone on the article on plasma display screen display surface 500 (A, B, C, D, E, F, G, H, Cyclic Redundancy Check value I) is carried out computing, obtains the Cyclic Redundancy Check value.
Then to each regional Cyclic Redundancy Check value of obtaining with compare by corresponding zone, whether differentiate each Cyclic Redundancy Check value identical.For example the Cyclic Redundancy Check value of the Cyclic Redundancy Check value of the image data of a-quadrant and a area image data compares, whether the Cyclic Redundancy Check value of differentiating image data is identical, the Cyclic Redundancy Check value of the Cyclic Redundancy Check value of the image data in B zone and b area image data compares, and whether the Cyclic Redundancy Check value of differentiating image data is identical.Here whether identical indication be to say whether Cyclic Redundancy Check value separately is identical.
Make and use the same method the image data value in judgement C zone and the image data value in c zone, the image data value in D zone and the image data value in d zone, the image data value in E zone and the image data value in e zone, the image data value in F zone and the image data value in f zone, the image data value in G zone and the image data value in g zone, the image data value in H zone and the image data value in h zone, whether the image data value in I zone is identical with the image data value in i zone.Though the a-quadrant is set at different values with a zone here, do not show in the drawings, in fact the a-quadrant is the identical zone of value with a zone.
To whether each regional data value identical differentiate after, compare with the reference value of having reserved, judge that present frame is dynamic image or static images.For example suppose above-mentioned reference value is set at 2 data value differences of permission, if the image data value in the image data value of a-quadrant and a zone, the image data value in B zone and the image data in b zone, the image data value in C zone and the image data value in c zone, the image data value in D zone and the image data value in d zone, the image data value in E zone and the image data value in e zone, the image data value in F zone and the image data value in f zone, the image data value in G zone and the image data value in g zone, the image data value in H zone is all identical with the image data value in h zone, has only the image data value in the image data value in I zone and i zone inequality.Be the conclusion of static images so with regard to the image that draws present frame.If the image data value in the image data value of a-quadrant and a zone, the image data value in B zone and the image data in b zone, the image data value in C zone and the image data value in c zone, the image data value in D zone and the image data value in d zone, the image data value in E zone and the image data value in e zone, the image data value in F zone and the image data value in f zone, the image data value in G zone is identical with the image data value in g zone, and the image data value in the image data value in H zone and h zone, the image data value in I zone and the image data value in i zone are inequality.Be the conclusion of dynamic image so with regard to the image that draws present frame.The reference value here can be regulated according to the characteristic of plasma panel and the various parameters such as characteristic of drive waveforms.For example can set corresponding zone have more than 3 the Cyclic Redundancy Check value not simultaneously then the image data of present frame be dynamic image.
The R that when the Cyclic Redundancy Check value in certain zone is carried out computing, each zone can be comprised, G, the corresponding Cyclic Redundancy Check value of B discharge cell lumps together the Cyclic Redundancy Check value of obtaining a zone.Also can obtain each R discharge cell, the G discharge cell, the all Cyclic Redundancy Check values of the R discharge cell of B discharge cell, the all Cyclic Redundancy Check values of G discharge cell, the all Cyclic Redundancy Check values of B discharge cell are obtained corresponding 3 the Cyclic Redundancy Check values in zone then.Press the R discharge cell, the G discharge cell, the B discharge cell obtain the dynamic image that separately Cyclic Redundancy Check value can be judged the comparison precision comparatively speaking.
Utilize said method, the portrait that image moves 400 pairs of present frames of test section is after dynamic image or static images are judged, handle by 401 pairs of portraits of portrait handling part, by deposited obedient portion 402 of subdomain and data sorting portion 403 image data is imported on the address electrode of PDP display then.
Above-mentioned portrait handling part 401 moves the result that test section 400 is judged according to described image, averages power (APL:Average Power Level) by the shadow data to present frame and handles, and processing is drawn a portrait in contrary gamma revisal and half-tone revisal.
Fig. 6 is the key diagram according to the image treatment method of plasma panel of the present invention.
As shown in Figure 6, form by following steps according to the image treatment method of plasma panel of the present invention:
Step S600, with etc. ground ion display board be divided into a certain size several zones.
Step S601 has judged whether to import the image data of a frame.
Step S602 according to the judged result of step S601, if imported image data then the image data value of a frame is not carried out the Cyclic Redundancy Check computing by several zones, obtains each regional Cyclic Redundancy Check value.
Whether step S603 behind the step S602, stores in the internal storage the image data Cyclic Redundancy Check value of previous frame and to judge.
Step S604, the judged result of step S603 is that the image data Cyclic Redundancy Check value of previous frame does not store in the internal storage, then the image data Cyclic Redundancy Check value of obtaining among the step S602 is stored in the internal storage.At this moment the Cyclic Redundancy Check value of the image data of storing in the internal storage is the Cyclic Redundancy Check value of the image data of present frame.After step S604, get back to whether having imported the step S601 that image data is judged.
Step S605, on the other hand, if being the image data Cyclic Redundancy Check value of previous frame, the judged result of step S603 stores in the internal storage, then the Cyclic Redundancy Check value with the image data of the former frame of storing in the Cyclic Redundancy Check value of the image data obtained among the step S602 and the storer compares, and the Cyclic Redundancy Check value with the image data obtained among the step S stores in the storer simultaneously.Here the Cyclic Redundancy Check value of the image data obtained among the step S602 is stored into reason in the storer and is for the Cyclic Redundancy Check value with the image data of next frame compares, the portrait of judging next frame is static images or dynamic image.
Step S606, the Cyclic Redundancy Check value of the image data of obtaining among the step S602 is compared with the Cyclic Redundancy Check value of image data of previous frame in being stored in internal storage then, judges that comparative result is whether in the reference value of having set.For example, 9 zones (a, b of selected plasma panel display surface as shown in Figure 5, c, d, e, f, g, h, other of the Cyclic Redundancy Check value of each image data i) and corresponding present frame 9 zones (A, B, C, D, E, F, G, H, whether the Cyclic Redundancy Check value of image data I) identical comparing.
In step S606, can compare with the Cyclic Redundancy Check value of image data of previous frame in being stored in internal storage to the Cyclic Redundancy Check value of the image data obtained among the step S602, judge that comparative result is whether in the reference value of having set, also can compare with the Cyclic Redundancy Check value of image data of previous frame in being stored in internal storage, judge whether comparative result surpasses the reference value of having set the Cyclic Redundancy Check value of the image data obtained among the step S602.If judge be comparative result whether surpass the reference value set later image processing process with judge that the image processing process after comparative result is whether in the reference value of having set is opposite.
Step S607, if the judged result of step S606 is for surpassing reference value, the portrait of then judging present frame is a dynamic image.Use S609 in the image data of the frame of the above-mentioned dynamic image portrait processing procedure afterwards.That is, present frame is identified as dynamic image, uses the image treatment method that adapts with above-mentioned dynamic image that the image data of importing is carried out coming out after the image processing.
Step S608, if the judged result of step S606 is in reference value, the portrait of then judging present frame is a static images.
Use in step S609, the image data of the frame of the above-mentioned static images portrait processing procedure afterwards.That is, present frame is identified as static images, uses the image treatment method that adapts with above-mentioned static images that the image data of importing is carried out coming out after the image processing.
Above-mentioned portrait handling part 401 moves the result that test section 400 is judged according to described image, averages power (APL:Average Power Level) by the shadow data to present frame and handles, and processing is drawn a portrait in contrary gamma revisal and half-tone revisal.
According to image treatment method of the present invention, each regional image data value is not stored in the storer (not shown), and only each regional Cyclic Redundancy Check value of image data accordingly is stored in the internal storage, the Cyclic Redundancy Check value of image data to storage compares then, distinguish static images or dynamic image, thereby the usage rate that can reduce storer in the image processing process like this improves image processing efficient.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claims of the present invention variation, the modification of the above embodiment.
