Description
本發明係有關於一種影像調整裝置，尤指一種用以產生過驅動像素值的影像調整裝置。The invention relates to an image adjusting device, in particular to an image adjusting device for generating overdriving pixel values.
在目前的液晶顯示技術中，會使用一種過驅動(over-drive)技術以改善液晶的反應速度，而一般來說，過驅動技術會依據目前圖框以及前一圖框的像素值差異，來決定過驅動像素值。舉例而言，假設前一圖框的原始像素值為100，目前圖框的原始像素值為200，則過驅動值可以被決定為230。由於過驅動技術已經為本發明所述領域中具有通常知識者所熟知，在此不予贅述。In the current liquid crystal display technology, an over-drive technique is used to improve the reaction speed of the liquid crystal.

就目前的過驅動技術而言，相同的灰階會造成相同的過驅動值(例如，假設前一圖框、目前圖框的一原始像素值分別為100、200，則過驅動像素值一定會被決定為230)，然而，由於在目前的液晶顯示面板中，共電極電壓的分佈並不均勻，且面板上每一個區域上液晶/背光源的漏光程度也不一致，因此，若是使用相同的過驅動像素值來進行顯示補償。則可能會造成畫面不均的情形。In the current overdrive technology, the same gray level will cause the same overdrive value (for example, if the original pixel value of the previous frame and the current frame is 100, 200 respectively, the overdrive pixel value will be It was decided to be 230). However, since the distribution of the common electrode voltage is not uniform in the current liquid crystal display panel, and the degree of light leakage of the liquid crystal/backlight on each area of the panel is also inconsistent, if the same is used, Drive pixel values for display compensation. This may result in uneven picture.

請參考第1圖，第1圖為依據本發明一實施例之影像調整裝置100的示意圖。如第1圖所示，影像調整裝置100包含有一過驅動像素值產生單元110、一圖框緩衝單元120、一補償單元130、一調整單元140以及一圖框輸出單元150。於本實施例中，影像調整裝置100係應用於一液晶顯示器中，且用以決定過驅動像素值。Please refer to FIG. 1. FIG. 1 is a schematic diagram of an image adjustment apparatus 100 according to an embodiment of the present invention. As shown in FIG. 1 , the image adjusting device 100 includes an overdrive pixel value generating unit 110 , a frame buffer unit 120 , a compensation unit 130 , an adjusting unit 140 , and a frame output unit 150 . In the embodiment, the image adjusting device 100 is applied to a liquid crystal display and is used to determine an overdrive pixel value.
在影像調整裝置100的操作上，首先，影像圖框會循序輸入至過驅動像素值產生單元110以及圖框緩衝單元120中，之後，過驅動像素值產生單元110會依據前一圖框FN-1以及目前圖框FN的一像素值，以決定出一第一過驅動像素值，舉例來說，假設前一圖框FN-1之一像素的原始像素值為100，目前圖框FN的之相對應像素的原始像素值為200，則目前圖框FN之該像素的過驅動像素值可以被決定為230。同時，補償單元130依據像素於目前圖框FN中的位置、原始像素值的液晶轉換極性以及目前圖框FN於影像調整裝置100所處理之複數個影像圖框中的次序，以決定一補償值Vc。接著，調整單元140依據第一過驅動像素值OD1以及補償值Vc以產生一第二過驅動像素值OD2。最後，依照上述步驟對整張目前圖框FN的每一個像素作類似的操作，以得到一輸出圖框，並經由圖框輸出單元150輸出至後端的電路或是顯示裝置。In the operation of the image adjustment apparatus 100, first, the image frame is sequentially input to the overdrive pixel value generating unit 110 and the frame buffer unit 120. Thereafter, the overdrive pixel value generating unit 110 according to the previous frame F N -1 and a pixel value of the current frame F N to determine a first overdrive pixel value, for example, assuming that the original pixel value of one of the pixels of the previous frame F N-1 is 100, the current frame The original pixel value of the corresponding pixel of F N is 200, and the overdrive pixel value of the pixel of the current frame F N can be determined to be 230. At the same time, the compensation unit 130 determines the position according to the position of the pixel in the current frame F N , the liquid crystal switching polarity of the original pixel value, and the order of the current frame F N in the plurality of image frames processed by the image adjusting device 100. Compensation value Vc. Next, the adjusting unit 140 generates a second overdrive pixel value OD2 according to the first overdrive pixel value OD1 and the compensation value Vc. Finally, a similar operation is performed on each pixel of the entire current frame F N according to the above steps to obtain an output frame and output to the circuit or display device at the back end via the frame output unit 150.
在補償單元130的操作上，首先，請參考第2圖，第2圖為目前所調整的像素值位於目前圖框FN中不同區域的示意圖。如第2圖所示，當補償單元130目前所處理的像素位於區域1，則補償單元130所產生的補償值Vc會不同於當補償單元130目前所處理的像素位於區域2時所產生的補償值Vc。另外，假設補償單元130目前所處理的像素位於區域1，但是像素的液晶極性轉換(由前一圖框FN-1切換到目前圖框FN時的液晶極性轉換)不同，則所產生的補償值Vc也會不同，詳細來說，當像素的液晶由正極性轉換到負極性時補償單元130所產生的補償值Vc會不同於當像素的液晶由負極性轉換到正極性時補償單元130所產生的補償值Vc。此外，假設補償單元130目前所處理的像素位於區域1，且像素的液晶極性轉換也相同，但是目前圖框FN於一組影像圖框中的次序不同，則所產生的補償值Vc也會不同，舉例來說，假設目前圖框FN為用來顯示立體影像的圖框資料(亦即每一組影像圖框具有兩個圖框(一左眼圖框以及一右眼圖框))，則當目前圖框FN為左眼圖框時補償單元130所產生的補償值Vc會不同於當目前圖框FN為右眼圖框時補償單元130所產生的補償值Vc。In the compensation operation unit 130, first refer to FIG. 2, a schematic diagram of the current frame F N different regions of the second graph the current pixel value is adjusted. As shown in FIG. 2, when the pixel currently processed by the compensation unit 130 is located in the area 1, the compensation value Vc generated by the compensation unit 130 may be different from the compensation generated when the pixel currently processed by the compensation unit 130 is located in the area 2. Value Vc. In addition, it is assumed that the pixel currently processed by the compensation unit 130 is located in the area 1, but the liquid crystal polarity conversion of the pixel (the liquid crystal polarity conversion when the previous frame F N-1 is switched to the current frame F N ) is different, and the generated The compensation value Vc may also be different. In detail, the compensation value Vc generated by the compensation unit 130 when the liquid crystal of the pixel is switched from the positive polarity to the negative polarity may be different from the compensation unit 130 when the liquid crystal of the pixel is converted from the negative polarity to the positive polarity. The generated compensation value Vc. In addition, it is assumed that the pixel currently processed by the compensation unit 130 is located in the area 1, and the liquid crystal polarity conversion of the pixel is also the same, but the current frame F N is different in the order of a group of image frames, and the generated compensation value Vc will also be generated. Different, for example, assume that the current frame F N is the frame data used to display the stereo image (that is, each group of image frames has two frames (one left eye frame and one right eye frame)) The compensation value Vc generated by the compensation unit 130 when the current frame F N is the left eye frame may be different from the compensation value Vc generated by the compensation unit 130 when the current frame F N is the right eye frame.
如上所述，補償單元130可以同時依據目前所處理的像素位於目前圖框FN為上的哪一個區域、像素的液晶極性轉換以及目前圖框FN於一組影像圖框中的次序來決定出最佳的補償值Vc，以補償過驅動像素值產生單元110所產生的第一過驅動像素值OD1，因此，可以避免先前技術中所述因為液晶面板上共電極電壓的分佈與液晶/背光源的漏光程度不一致而造成影像畫面不均的問題。As described above, the compensation unit 130 can simultaneously determine which region of the current frame F N is on the pixel, the liquid crystal polarity conversion of the pixel, and the order of the current frame F N in a group of image frames. The optimal compensation value Vc is obtained to compensate for the first overdrive pixel value OD1 generated by the overdrive pixel value generating unit 110. Therefore, the distribution of the common electrode voltage on the liquid crystal panel and the liquid crystal/backlight can be avoided as described in the prior art. The problem of the light leakage of the source is inconsistent and the image is uneven.
此外，補償單元130所產生的補償值Vc可以為一增益值(gain)、一偏差值(offset)或是任何可以用來調整第一過驅動像素值OD1的補償值。舉例來說，當補償值Vc為一增益值時，調整單元140即為一乘法器以將第一過驅動像素值OD1與補償值Vc相乘以得到第二過驅動像素值OD2；當補償值Vc為一偏差值時，調整單元140即為一加法器(減法器)以將第一過驅動像素值OD1與補償值Vc相加(相減)以得到第二過驅動像素值OD2。In addition, the compensation value Vc generated by the compensation unit 130 may be a gain value, an offset value, or any compensation value that can be used to adjust the first overdrive pixel value OD1. For example, when the compensation value Vc is a gain value, the adjusting unit 140 is a multiplier to multiply the first overdrive pixel value OD1 by the compensation value Vc to obtain a second overdrive pixel value OD2; When Vc is a deviation value, the adjustment unit 140 is an adder (subtractor) to add (subtract) the first overdrive pixel value OD1 and the compensation value Vc to obtain a second overdrive pixel value OD2.
此外，於本發明之一實施例中，補償單元130係使用一對照表來產生補償值Vc。Moreover, in one embodiment of the invention, the compensation unit 130 uses a look-up table to generate the compensation value Vc.
此外，於上述影像調整裝置100中，補償單元130係同時依據目前所處理的像素位於目前圖框FN上的哪一個區域、像素的液晶極性轉換以及目前圖框FN於一組影像圖框中的次序來決定出最佳的補償值Vc，然而，本發明並不以此為限，於本發明之其他實施例中，補償單元130可以僅依據目前所處理的像素位於目前圖框FN上位置來決定補償值Vc；或是補償單元130僅依據目前所處理的像素位於目前圖框FN為上位置以及液晶極性轉換來決定補償值Vc；亦或是補償單元130僅依據目前所處理的像素位於目前圖框FN上位置以及目前圖框FN於一組影像圖框中的次序來決定補償值Vc，這些設計上的變化均應隸屬於本發明的範疇。In addition, in the image adjusting apparatus 100, the compensation unit 130 simultaneously determines which region of the current frame F N the pixel is currently processed, the liquid crystal polarity conversion of the pixel, and the current frame F N in a group of image frames. The order of the present is used to determine the optimal compensation value Vc. However, the present invention is not limited thereto. In other embodiments of the present invention, the compensation unit 130 may be located only in the current frame F N according to the currently processed pixel. The upper position determines the compensation value Vc; or the compensation unit 130 determines the compensation value Vc only according to the current processing pixel located at the current frame F N and the liquid crystal polarity conversion; or the compensation unit 130 is only processed according to the current the current pixel is located in the position of frame F N and F N current frame a set of images in order to determine the frame of FIG compensation value Vc, these design changes should belong to the scope of the present invention.
請參考第3圖，第3圖為依據本發明另一實施例之影像調整裝置300的示意圖。如第3圖所示，影像調整裝置300包含有一過驅動像素值產生單元310、一圖框緩衝單元320以及一圖框輸出單元330。於本實施例中，影像調整裝置300係應用於一液晶顯示器中，且用以決定過驅動像素值。Please refer to FIG. 3, which is a schematic diagram of an image adjusting device 300 according to another embodiment of the present invention. As shown in FIG. 3, the image adjusting device 300 includes an overdrive pixel value generating unit 310, a frame buffer unit 320, and a frame output unit 330. In the embodiment, the image adjusting device 300 is applied to a liquid crystal display and used to determine the overdrive pixel value.
在影像調整裝置300的操作上，首先，影像圖框會循序輸入至過驅動像素值產生單元310以及圖框緩衝單元320中，之後，過驅動像素值產生單元310會依據前一圖框FN-1以及目前圖框FN的像素值、像素於目前圖框FN中的位置、原始像素值的液晶轉換極性以及目前圖框FN於影像調整裝置300所處理之複數個影像圖框中的次序，以決定過驅動像素值OD。最後，依照上述步驟對整張目前圖框FN的每一個像素作類似的操作，以得到一輸出圖框，並經由圖框輸出單元330輸出至後端的電路或是顯示裝置。In operation image adjusting apparatus 300, first, the image frame will be sequentially input to the overdrive pixel value generating unit 310 and the frame buffer unit 320, after the overdrive pixel value generating unit 310 will be based on the previous frame F N -1 and the current frame F N pixel values, the pixel in the current frame F N in position, the liquid crystal of the original pixel value and reverse polarity current frame F N 300 to a plurality of processing a video image adjusting apparatus of FIG box The order to determine the overdrive pixel value OD. Finally, a similar operation is performed on each pixel of the entire current frame F N according to the above steps to obtain an output frame, and outputted to the circuit or display device at the back end via the frame output unit 330.
影像調整裝置300與第1圖所示之影像調整裝置100的差異在於影像調整裝置100需要先產生一第一過驅動像素值OD1，之後再產生一補償值Vc來補償第一過驅動像素值OD1；而影像調整裝置300可以直接產生所需要的過驅動像素值OD。The difference between the image adjustment device 300 and the image adjustment device 100 shown in FIG. 1 is that the image adjustment device 100 needs to generate a first overdrive pixel value OD1 first, and then generate a compensation value Vc to compensate the first overdrive pixel value OD1. The image adjusting device 300 can directly generate the required overdrive pixel value OD.
於本發明之一實施例中，過驅動像素值產生單元310使用多個對照表以產生過驅動像素值OD，舉例來說，參考第2圖及上述有關第1圖所示之影像調整裝置100的說明，該多個對照表可以依目前所處理之像素的特性分別為：對照表1：區域1、液晶極性由負轉正、左眼圖框；對照表2：區域1、液晶極性由負轉正、右眼圖框；對照表3：區域1、液晶極性由正轉負、左眼圖框；對照表4：區域1、液晶極性由正轉負、右眼圖框；對照表5：區域2、液晶極性由負轉正、左眼圖框；對照表6：區域2、液晶極性由負轉正、右眼圖框；對照表7：區域2、液晶極性由正轉負、左眼圖框；對照表8：區域2、液晶極性由正轉負、右眼圖框；其中每一個對照表大致上可以如第4圖所示，第4圖所示之對照表左側與上方分別為圖框FN-1、FN的像素值，而表內數字為過驅動像素值OD。In an embodiment of the present invention, the overdrive pixel value generating unit 310 uses a plurality of lookup tables to generate an overdrive pixel value OD. For example, referring to FIG. 2 and the image adjustment apparatus 100 shown in FIG. 1 above. In the description, the plurality of comparison tables can be respectively according to the characteristics of the currently processed pixels: comparison table 1: region 1, liquid crystal polarity from negative to positive, left eye frame; comparison table 2: region 1, liquid crystal polarity from negative to positive , right eye frame; comparison table 3: area 1, liquid crystal polarity from positive to negative, left eye frame; comparison table 4: area 1, liquid crystal polarity from positive to negative, right eye frame; comparison table 5: region 2 Liquid crystal polarity from negative to positive and left eye frame; comparison table 6: area 2, liquid crystal polarity from negative to positive and right eye frame; comparison table 7: area 2, liquid crystal polarity from positive to negative, left eye frame; Table 8: Area 2, liquid crystal polarity is changed from positive to negative, right eye frame; each of the comparison tables can be roughly as shown in Fig. 4, and the left and top of the comparison table shown in Fig. 4 are respectively frame F N -1 , the pixel value of F N , and the number in the table is the overdrive pixel value OD.
此外，於上述影像調整裝置300中，過驅動像素值產生單元310係同時依據目前所處理的像素位於目前圖框FN上的哪一個區域、像素的液晶極性轉換以及目前圖框FN於一組影像圖框中的次序來決定出最佳的補償值Vc，然而，本發明並不以此為限，於本發明之其他實施例中，過驅動像素值產生單元310可以僅依據目前所處理的像素位於目前圖框FN上位置來決定補償值Vc；或是過驅動像素值產生單元310僅依據目前所處理的像素位於目前圖框FN上位置以及液晶極性轉換來決定補償值Vc；亦或是過驅動像素值產生單元310僅依據目前所處理的像素位於目前圖框FN上位置以及目前圖框FN於一組影像圖框中的次序來決定補償值Vc，這些設計上的變化均應隸屬於本發明的範疇。In addition, in the image adjusting device 300, the overdrive pixel value generating unit 310 simultaneously determines which region of the current frame F N the pixel is currently on, the liquid crystal polarity conversion of the pixel, and the current frame F N according to the currently processed pixel. The order of the image frame is used to determine the optimal compensation value Vc. However, the present invention is not limited thereto. In other embodiments of the present invention, the overdrive pixel value generating unit 310 may only process the current The pixel is located at the current frame F N to determine the compensation value Vc; or the overdrive pixel value generating unit 310 determines the compensation value Vc based only on the position of the currently processed pixel located on the current frame F N and the liquid crystal polarity conversion; Or the overdrive pixel value generating unit 310 determines the compensation value Vc according to the order of the currently processed pixel located on the current frame F N and the current frame F N in a group of image frames. Variations are all within the scope of the invention.
