Abstract

A method to display dynamic image is disclosed. This method includes firstly calculate a minimum sum of absolute difference (SAD) according to a first frame data corresponding to a clock t and a second frame data corresponding to a clock t+1. Secondly, the first frame data is divided into a plurality of first sub-frame datas while the second frame data is also divided into a plurality of second sub-frame datas. Thirdly, choose one of these first sub-frame datas as a standard and compare the rest of the first sub-frame datas to the chosen sub-frame data to gain a first detail ratio number (DRN). Also, choose one of these second sub-frame datas as a standard and compare the rest of the second sub-frame datas to the chosen sub-frame data to gain a second DRN. Then, compare the first DRN to a first standard value to gain a first result while a second result is gained via comparing the second DRN to a second standard value. According to the difference between the first and the second results, determine a frame moving vector. At last, a middle frame is inserted between the first and the second frames.

Description

201026023 六、發明說明: 【發明所屬之技術領域】 本發明係關於一種顯示模組、顯示裝置及其影像顯示 方法,特別關於一種可根據亮度變化程度以估算影像顯示 、 的影像顯示模組、影像顯示裝置及其動態影像顯示方法。 • 【先前技術】 ❹ 由於液晶面板響應時間較長,如何降低殘影與抖動問 題一直是液晶電視設計中最重要的課題之一,尤其在高晝 質電視中,更是不容忽視。因此,為解決此一問題,目前 市場上已逐漸導入晝面更新率(FrarneRate)為l〇〇/l2〇Hz 的面板’來取代以往畫面更新率為5〇/6〇Hz的面板。不過, 光是提高面板畫面更新率並無太大意義,還必須設法讓訊 號來源也能相互匹配,才能達到真正改善影像品質的目 的’因而使付動悲估鼻(M〇ti〇n Estimation,ME)與動態 ❹ 補償(Moti〇n Compensation,MC)的技術備受重視。 也就是說,當所使用的面板晝面更新率已經更新為 100/120HZ的規格時,若影像訊號來源仍停留在5〇/6〇Hz . 的規格時,則必須導入ME/MC技術來進行刷新率轉換 (Frame Rate Conversion ’ FRC),俾使得原本為 50/60Hz ' 的影像訊號能夠提升至l〇〇/120Hz,藉以呈現出最佳的影 像品質。而用以實現刷新率轉換的做法有許多種,目前常 見的手段多半是在50/60Hz的每一晝框間插入黑色或灰色 晝面,如此雖可達到消除殘影的目的,卻也因而降低榮幕 201026023 顯示的亮度和對比度。 更值得注意的是,在目前的技術背景下,影像的估算 並無法將相鄰的二晝框所對應的亮度納入計算的參考,而 僅能簡單地將相鄰二晝框的中具有相同位置的子晝框進 行運算以獲得晝框的移動向量,不過利用這樣的計算方式 所獲得的晝框移動向量經常會因為相鄰兩晝框在亮度上 的差異,而導致估算結果的偏差,使得插入的晝框無法流 暢地與前、後晝框相連結,而影響顯示品質。 因此,如何提供一種影像顯示模組、影像顯示裝置及 其動態影像顯示方法,實屬當前重要課題之一。 【發明内容】 有鑑於上述課題,本發明之目的為提供一種影像顯示 模組、影像顯示裝置及其動態影像顯示方法,其係將相鄰 兩畫框的細節差異量一併做為計算晝框移動向量的參數

值,反之,當第一細節量值小於第一標準值,則第一比對 結果所對應的數值係為零,也就是說,唯有當第一細節量 值大於等於所設定的第一標準值時,第一細節量值才會對 影像的動態估算造成影響;而相似地,對於第二細節量值 與第二標準值之間的比對,亦相同於上述第一細節量值與 第一標準值之間的比對方式,換言之,亦唯有在第二細節 量值大於等於所設定的第二標準值時,第二細節量值才會 對影像的動態估算造成影響。 再如步驟S05所示可知,當於步驟S04中獲得第一比 對結果與第二比對結果後,更在此步驟中依據所獲得的第 一比對結果與第二比對結果的差值以決定一畫框移動向 量,其中,如步驟S051所示,當第一比對結果等於第二 比對結果時,也就是第一比對結果與第二比對結果的差值 為零,則晝框移動向量係直接以最小絕對差總和值為計算 參數,舉例來說,在此狀況下的晝框移動向量係與最小絕 對差總和值成正比,不過,當第一比對結果不等於第二比 對結果時,其係如步驟S052所示,也就是第一比對結果 與第二比對結果的差值不為零,則晝框移動向量係必須同 時以最小絕對差總和值、第一細節量值與第二細節量值為 計算參數,此時的晝框移動向量除了根據最小絕對差總和 201026023 值的決定外,更同時參考第一細節量值與第二細節量值的 影響。 由此可知,當第一晝框資料中的第一子晝框資料與第 二晝框資料中的第二子畫框資料在亮度上沒有太大的改 變時,由於以亮度變異量為依據的第一細節量值與第二細 節量值均在一定的標準範圍内,因此在估算晝框移動向量 時,並不需要將亮度的變異納入計算的考量,不過,當第 一晝框資料中的第一子晝框資料與第二晝框資料中的第 參 二子晝框資料在亮度上有一定程度的改變時,則經過上述 步驟S04的比對結果後,係於本步驟中將與亮度相關的第 一細節量值與第二細節量值一併納入晝框移動向量的估 算。 最後,在步驟S06中,則係利用晝框移動向量以計算 出内插於第一畫框與第二晝框之間的一中間晝框,俾使第 一畫框轉換為第二晝框時,得以藉由此一中間晝框而呈現 φ 出更流暢的影像變化。 本發明之動態影像顯示方法係可應用於一影像顯示 模組中,以進一步改善影像的顯示品質,而影像顯示模組 . 的示意圖請參見圖4A。於此實施例中,影像顯示模組40 係具有一顯示面板403以用來顯示影像,而此影像顯示模 組40係包含一影像處理單元以及一時序控制單元402,於 此,影像處理單元係以縮放器(Scaler) 401為例說明,不 過並非用以限定本發明的範圍。 為使上述之方法得以實現於影像顯示模組40中,首 11 201026023 先,在影像顯示模組40中的縮放器401係會擷取(或接 收)對應於時序t的第一晝框資料FD1與對應於時序t+1 的第二畫框資料FD2,並利用上述之影像顯示方法以調整 所接收到的影像資料(包含第一晝框資料FD1與第二晝框 . 資料FD2),待完成該方法後再將影像資料送入時序控制 • 單元(Timing Controller) 402,並進行後續之 ME/MC 演 ' 算法,俾藉以驅動影像顯示裝置40的顯示面板403能顯 示出最終的影像,換言之,將相鄰晝框的亮度變化納入估 算的方法係主要執行於顯示裝置40的縮放器401内。 另,雖上述的ME/MC演算法係執行於時序控制單元 402,不過在實際的應用與設計上,亦可如圖4B所示, ME/MC演算法係可執行於縮放器401,而亦即,ME/MC 係藉由縮放器401或時序控制單元402以執行,並不會影 響到縮放器401及時序控制單元402的原有作動。 另,將上述的影像顯示模組與一背光模組搭配應用 φ 時,則可構成一影像顯示裝置,其中,為使背光模組所產 生的光線得以傳送至影像顯示模組,背光模組係與影像顯 示模組相對設置,而由於每一元件的運算方式、影像顯示 . 模組的特徵以及動態影像顯示方法均已詳述於上,於此將 不再贅述。 綜上所述,本發明之一種動態影像顯示方法除了可利 用前、後兩個相鄰晝框的晝面做為參考依據,並利用 ME/MC演算法以推算出中間晝框外,更在進行影像估算 的同時,將兩相鄰晝框的亮度變化納入為估算的參數之 12 201026023 一,藉以達到晝面轉換的流暢並提高影像的顯示效果。與 習知技術相較,本發明所揭露的動態影像顯示方法係可將 亮度變化納入為畫框移動向量的參數之一,俾使得内插晝 框與相鄰兩晝框之間的流暢度更加提升。 以上所述僅為舉例性,而非為限制性者。任何未脫離 本發明之精神與範疇,而對其進行之等效修改或變更,均 應包含於後附之申請專利範圍中。

Description of the Invention: [Technical Field] The present invention relates to a display module, a display device and an image display method thereof, and more particularly to an image display module and image capable of estimating image display according to the degree of change in brightness Display device and its dynamic image display method. • [Prior Art] ❹ Due to the long response time of LCD panels, how to reduce image sticking and jitter has always been one of the most important topics in LCD TV design, especially in high-definition TVs. Therefore, in order to solve this problem, a panel with a FrneRate of l〇〇/l2〇Hz has been gradually introduced on the market to replace the panel with a previous picture update rate of 5〇/6〇Hz. However, it does not make much sense to improve the panel update rate. It is also necessary to try to match the signal sources to achieve the goal of truly improving the image quality. This makes it possible to estimate the nose (M〇ti〇n Estimation, ME) and the technology of dynamic ❹ compensation (Moti〇n Compensation, MC) are highly valued. That is to say, when the panel update rate used has been updated to 100/120HZ, if the image signal source still stays at the specification of 5〇/6〇Hz., ME/MC technology must be imported. The frame rate conversion (FRC) allows the original 50/60Hz image signal to be increased to l〇〇/120Hz for the best image quality. There are many ways to achieve the refresh rate conversion. Most of the common methods are to insert a black or gray face between each frame of 50/60 Hz, so that the purpose of eliminating the residual image can be reduced. The brightness and contrast displayed by the glory 201026023. More notably, in the current technical background, the estimation of the image does not allow the brightness corresponding to the adjacent two frames to be included in the calculation reference, but can simply have the same position in the adjacent two frames. The sub-frame is operated to obtain the motion vector of the frame, but the frame motion vector obtained by such calculation method often causes the deviation of the estimation result due to the difference in brightness between the adjacent two frames, so that the insertion is made. The frame cannot be smoothly connected to the front and back frames, which affects the display quality. Therefore, how to provide an image display module, an image display device and a dynamic image display method thereof is one of the current important topics. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide an image display module, an image display device, and a dynamic image display method thereof, which are used as a calculation frame for the difference of the details of two adjacent frames. One of the parameters of the motion vector, wherein the ratio of the detail difference is the difference in brightness between each sub-frame and the sub-frame of the comparison reference in the frame, so that the adjacent difference can be adjacent The brightness change of the two frames is included in the estimation to achieve smooth transition of the facet and improve the display of the image. In order to achieve the above object, a dynamic image display method according to the present invention comprises the following steps: first, calculating according to the first frame data corresponding to the time sequence t and the second frame data corresponding to the time sequence t+i The sum of the minimum absolute difference; secondly, the first frame data is divided into the first sub-frame data, and the second frame data is also divided into the second number 201026023 sub-frames; Select one of the first sub-frame data to be the comparison reference, and compare it with the remaining first-sub-frames to obtain a first detail quantity, and also select this The eighth of the second sub-frame data is used as the comparison benchmark, and the second sub-frame data is compared with the remaining second sub-frame data. The second detail value is obtained. Fourth, the first-level quantity is obtained. Comparing with a = one standard value to obtain a first comparison result, and comparing the first, ', and the second standard value to obtain a second alignment; 5. According to the difference between the first comparison result and the second comparison result, the decision-frame movement is performed. Amount; Sixth, day block using motion vectors to calculate a frame intermediate between the first day and the second frame to frame interpolation. In the above fifth step, when the difference between the first comparison result and the second comparison result is zero, the planting motion vector is the sum of the minimum absolute differences (that is, the absolute value of the difference value). The sum is calculated for the parameter. When the difference between the first = pair result and the second comparison result is not equal to zero, the frame movement vector is simultaneously the minimum absolute difference sum value (that is, the absolute value of the difference is calculated). The sum), the first detail value and the second detail value are calculated from the parameters. In order to achieve the above object, the image display module driven by the dynamic image display method disclosed in the above invention has a display panel for displaying a video image. The image display module includes an image processing unit and: 2 sequence control unit. The image processing unit calculates the frame motion vector by using the above-mentioned moving shadow=no method'; the timing control unit is the image processing unit and the display panel, and the timing control unit receives the frame motion vector and drives the frame Display panel to display images. In order to achieve the above object, according to the image display and the backlight module driven by the dynamic image display 201026023 method disclosed in the above, the image frequency/, the system includes an image display (four), and is placed to make the backlight fishery The generated =, # domain groups are grouped with each other. The image display module has a "frequency" which can be supplied to the image display unit and the timing control unit. The image processing single-state image display method is used to calculate the frame moving direction 】 timing]==^^ unit and the display panel to display the image. —#向向1 and worse to drive the display panel 亍f詈; 5 know that the invention of the image display module, image display = and its moving image display method in addition to the use of the front and rear two adjacent dens The noodles of the cultivating materials are used as a reference basis, and the bribe hall is used: the data corresponding to the middle frame is calculated, so that the image can be estimated by inserting the middle frame between the front and the back: At the same time, the brightness change of two adjacent frames is included as one of the estimated parameters, #, ^ to achieve: smooth and improve the display effect of the two images. The dynamic scene disclosed by the prior art, the illuminating scene disclosed in the present description, can incorporate the brightness change into one of the parameters of the frame motion vector, so that the smoothness between the adjacent frames of the interpolated frame is made. The degree is even higher. [Embodiment] Hereinafter, a moving image display method according to a preferred embodiment of the present invention will be described with reference to the related drawings. &1 Please refer to FIG. 1 , which is a kinetic energy shadow disclosed in the present invention. 7 201026023 Γί: Fang ΐ Γ: Example. According to FIG. 1, it is known that seven main steps f are revealed. In step S01, according to the time corresponding to the time t: the bedding material and the second frame data corresponding to the time sequence t+1 are calculated - the absolute The sum of the differences. Dare sheep, ', Tian Lai', in step SO; [in the second step of Figure 2, first, as shown in step s〇u, draw the first time sequence t+l corresponding to the time sequence t In the SG12, the first frame data is compared with the second frame data of the 丨, "", and each operation is calculated. The first step two: the sum of the absolute differences between the materials; finally, as the second = the smallest one of all the absolute difference sum values - the selected nr pairs of the difference sum value corresponding to the red square frame data is The second frame frame disclosed in the step Xie:-: Step S02 towel' divides the first frame data into plural numbers; Complex structure ^ 1 = - 昼 frame data in the plural - the first sub-frame data second child * 偷 steal ^ 昼 frame towel _ points of the plural, two: the matrix arrangement is the same, at the same time, because, such as = = The number of the first sub-frame data divided is the number of the second sub-frame data divided in the other. The configuration and arrangement of the non-species implementation of the framework of the poor materials are only for the invention of the invention, only the 里, the sample, when the lack of, also, the first frame information and the second frame of the information 201026023 two]; :: The pattern of different matrix arrangements, and the number of the first and the sub-frame data may be the same or different. [The second item is selected in all the first sub-frame data. 2: The frame data and the rest of the first sub-frame::: to a first detail value, because 栌α 叮 comparison The information on the box is so that the selection is also based on all the second sub-pictures, and the second: the second sub-picture frame data is obtained as a comparison with the base line - the second detail value. In the case of the foreigner, ., and Tian, the calculation of the 曰 value of the first-level detail value is based on the case of the guest, and the following is only used as the benchmark for the comparison. As shown in Figure 3:: The first sub-frame material in the oyster family is exemplified. 资 / 八, 斤不 弟 昼 昼 资料 资料 资料 资料 弟 弟 弟 弟 弟 弟 :: :: :: :: :: :: :: :: :: :: :: :: :: :: :: :: :: , (1), (1), ~, :;: ❹ is the comparison benchmark, and when the remaining eight first-frame data 'ancient 3'4^6'7'8 has three first sub-large s1 The difference between the brightness of the party and the younger brother's frame data 0 =, when the brightness between the two first-sub-frame data is different, the brightness difference between the data of the sub-frame is greater than - the preset value, then After the first detail obtained after the comparison, in the step of the step, the step obtained in step SG3 is obtained; the throttle value is compared with the -th-standard value, and the second detail amount is also obtained. The value is compared with a second standard value, and the first comparison result is obtained, wherein the value of the first standard value and the second standard value for 201026023 may be the same value, and when the first detail quantity is compared And the value of the first comparison value and the first standard value, in other words, when the first detail quantity is greater than or equal to the first standard value, the value of the first comparison result That is, the value corresponding to the first detail magnitude, and conversely, when the first detail magnitude is less than the first standard value, the first comparison result The corresponding value is zero, that is, only when the first detail magnitude is greater than or equal to the set first standard value, the first detail magnitude will affect the dynamic estimation of the image; and similarly, for The comparison between the second detail value and the second standard value is also the same as the comparison between the first detail quantity and the first standard value, in other words, only the second detail quantity is greater than or equal to When the second standard value is set, the second detail value will affect the dynamic estimation of the image. As shown in step S05, after the first comparison result and the second comparison result are obtained in step S04, the difference between the obtained first comparison result and the second comparison result is further determined in this step. Determining a frame motion vector, wherein, as shown in step S051, when the first comparison result is equal to the second comparison result, that is, the difference between the first comparison result and the second comparison result is zero, then The frame motion vector directly calculates the parameter with the minimum absolute difference sum. For example, the frame motion vector in this case is proportional to the sum of the minimum absolute differences, but when the first comparison result is not equal to the first When the result of the second comparison is as shown in step S052, that is, the difference between the first alignment result and the second comparison result is not zero, then the frame motion vector system must simultaneously have the minimum absolute difference sum value, A detail magnitude and a second detail magnitude are calculation parameters, and the frame motion vector at this time refers to the influence of the first detail magnitude and the second detail magnitude in addition to the decision of the minimum absolute difference sum 201026023 value. It can be seen that when the first sub-frame data in the first frame data and the second sub-frame data in the second frame data do not change much in brightness, due to the brightness variation amount The first detail magnitude and the second detail magnitude are both within a certain standard range, so when estimating the frame motion vector, it is not necessary to incorporate the luminance variation into the calculation consideration, but when in the first frame data When the first sub-frame data and the second sub-frame data in the second frame data have a certain degree of change in brightness, the comparison result of the above step S04 is related to the brightness in this step. The first detail magnitude is combined with the second detail magnitude to include an estimate of the frame motion vector. Finally, in step S06, the frame is moved by the frame to calculate an intermediate frame interpolated between the first frame and the second frame, so that when the first frame is converted into the second frame It is possible to present a smoother image change by using this intermediate frame.
