Description
本發明涉及一種顯示裝置的節能控制系統及其方法，特別是以影像狀態選擇執行相應的節能控制方式來提高節能效率之基於影像狀態的節能控制系統及其方法。The invention relates to an energy-saving control system and a method thereof for a display device, in particular to an image-state-based energy-saving control system and a method thereof for selecting an energy-saving control method to improve energy-saving efficiency.
近年來，隨著液晶顯示器的普及與蓬勃發展，如何使液晶顯示器更為節能也逐漸成為各家廠商亟欲解決的問題之一。In recent years, with the popularity and flourishing of liquid crystal displays, how to make liquid crystal displays more energy-efficient has gradually become one of the problems that various manufacturers are eager to solve.
一般而言，傳統液晶顯示器的節能方式通常是透過調整背光源來達成，例如動態背光調整技術（Content Adaptive Brightness Control, CABC）便是根據不同的影像提供不同光強度的背光源，避免因為持續使用高強度的背光來達到省電的目的。然而，單純以調整背光源來達到省電的方式已經無法滿足使用者對於節能的需求。In general, the energy saving method of the conventional liquid crystal display is usually achieved by adjusting the backlight. For example, the Content Adaptive Brightness Control (CABC) is a backlight that provides different light intensities according to different images, and avoids continuous use. High-intensity backlighting for power saving purposes. However, simply adjusting the backlight to save power has not been able to meet the user's need for energy saving.
有鑑於此，便有廠商提出根據影像的狀態來控制顯示面板的驅動方式，使其在不同的影像狀態驅動相應的電路，以便進一步節省電能。然而，單純根據影像狀態切換不同的驅動方式，可能會有短時間內反覆切換不同驅動方式導致反而更耗電的情況，因此具有無法有效解決顯示裝置的節能效率不佳的問題。In view of this, some manufacturers have proposed to control the driving mode of the display panel according to the state of the image, so that the corresponding circuit is driven in different image states, thereby further saving power. However, simply switching between different driving modes according to the image state may result in a situation in which the different driving modes are switched over and over again in a short period of time, which may result in more power consumption. Therefore, there is a problem that the energy saving efficiency of the display device cannot be effectively solved.
綜上所述，可知先前技術中長期以來一直存在顯示裝置的節能效率不佳之問題，因此實有必要提出改進的技術手段，來解決此一問題。In summary, it can be seen that there has been a problem in the prior art that the energy saving efficiency of the display device is not good for a long time, and therefore it is necessary to propose an improved technical means to solve this problem.
本發明揭露一種基於影像狀態的節能控制系統及其方法。The invention discloses an energy saving control system based on image state and a method thereof.
首先，本發明揭露一種基於影像狀態的節能控制系統，此系統包含：偵測模組、判斷模組、選擇模組及控制模組。其中，偵測模組用以在播放影像時，持續偵測影像的每一訊框之內容以計算出當前訊框與前一訊框之影像特徵值並進行比對，以及根據比對結果調整計數值；判斷模組用以在此計數值大於動態門檻值時，將影像的狀態設定為動態，並且直到此計數值小於靜態門檻值時，才將影像的狀態切換為靜態；選擇模組用以在影像的狀態為動態時，選擇適用於動態影像的節能控制方式，在影像的狀態為靜態時，自禁能電路及停止在記憶體中更新影像的節能控制方式中選擇至少其中之一；以及控制模組用以切換為選擇模組選擇的節能控制方式以顯示影像。First, the present invention discloses an image-based energy-saving control system, which includes: a detection module, a determination module, a selection module, and a control module.

Counting value; the determining module is configured to set the state of the image to be dynamic when the count value is greater than the dynamic threshold value, and switch the state of the image to static until the count value is less than the static threshold value; When the state of the image is dynamic, the energy-saving control mode suitable for the motion image is selected, and when the state of the image is static, at least one of the disable circuit and the energy-saving control mode for stopping the image update in the memory are selected; And the control module is configured to switch to the energy-saving control mode selected by the selection module to display the image.
另外，本發明揭露一種基於影像狀態的節能控制方法，其步驟包括：在播放影像時，持續偵測影像的每一訊框之內容以計算出當前訊框與前一訊框之影像特徵值並進行比對，以及根據比對結果調整計數值；在計數值大於動態門檻值時，將影像的狀態設定為動態，並且直到此計數值小於靜態門檻值時，將影像的狀態切換為靜態；在影像的狀態為動態時，選擇適用於動態影像的節能控制方式，在影像的狀態為靜態時，自禁能電路及停止在記憶體中更新該影像的節能控制方式中選擇至少其中之一；以及切換為選擇的節能控制方式以顯示此影像。In addition, the present invention discloses an image-based energy-saving control method, which includes the steps of: continuously detecting the content of each frame of the image to calculate the image feature values of the current frame and the previous frame while playing the image. Performing an alignment and adjusting the count value according to the comparison result; when the count value is greater than the dynamic threshold value, setting the state of the image to dynamic, and switching the state of the image to static until the count value is less than the static threshold value; When the state of the image is dynamic, the energy-saving control mode suitable for the motion image is selected, and when the state of the image is static, at least one of the disable circuit and the energy-saving control mode for stopping the update of the image in the memory are selected; Switch to the selected energy saving control mode to display this image.
本發明所揭露之系統與方法如上，與先前技術的差異在於本發明是透過持續偵測影像的每一訊框之內容以計算出當前訊框與前一訊框之影像特徵值並進行比對，並且根據比對結果調整計數值，當計數值大於動態門檻值時，選擇動態的節能控制方式，當計數值小於靜態門檻值時，自禁能電路及停止在記憶體中更新影像的節能控制方式中選擇至少其中之一，以便使用選擇的節能控制方式來顯示影像。The system and method disclosed in the present invention are different from the prior art in that the present invention continuously calculates and compares the image feature values of the current frame and the previous frame by continuously detecting the content of each frame of the image. And adjusting the count value according to the comparison result, when the count value is greater than the dynamic threshold value, selecting a dynamic energy-saving control mode, when the count value is less than the static threshold value, the self-blocking circuit and the energy-saving control for stopping updating the image in the memory Select at least one of the modes to display the image using the selected energy saving control method.
透過上述的技術手段，本發明可以達成以影像狀態選擇執行相應的節能控制方式來提高顯示裝置的節能效率之技術功效。Through the above technical means, the present invention can achieve the technical effect of selecting the corresponding energy-saving control mode to improve the energy-saving efficiency of the display device in the image state.
以下將配合圖式及實施例來詳細說明本發明之實施方式，藉此對本發明如何應用技術手段來解決技術問題並達成技術功效的實現過程能充分理解並據以實施。The embodiments of the present invention will be described in detail below with reference to the drawings and embodiments, so that the application of the technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented.
在說明本發明所揭露之基於影像狀態的節能控制系統及其方法之前，先對本發明所自行定義的名詞作說明，本發明所述的動態門檻值是用來判斷影像是否為動態的條件參數，例如：大於動態門檻值代表影像為動態；而所述靜態門檻值則是用來判斷影像是否為靜態的條件參數，例如：小於靜態門檻值代表影像為靜態。另外，動態門檻值及靜態門檻值皆為正整數，並且允許以按壓實體按鍵或點選虛擬按鍵的方式進行設定，至於詳細的判斷影像是否為靜態的方式將在稍後作說明。Before describing the image state-based energy-saving control system and the method thereof disclosed in the present invention, the nouns defined by the present invention are first described. The dynamic threshold value of the present invention is a condition parameter for determining whether an image is dynamic. For example, the value greater than the dynamic threshold indicates that the image is dynamic; and the static threshold is used to determine whether the image is static. For example, the value less than the static threshold indicates that the image is static. In addition, both the dynamic threshold and the static threshold are positive integers, and are allowed to be set by pressing a physical button or clicking a virtual button, and a detailed manner of determining whether the image is static will be described later.
以下配合圖式對本發明基於影像狀態的節能控制系統及其方法做進一步說明，請先參閱「第1圖」，「第1圖」為本發明基於影像狀態的節能控制系統之系統方塊圖，此系統包含：偵測模組110、判斷模組120、選擇模組130及控制模組140。其中，偵測模組110用以在播放影像時，持續偵測影像的每一訊框（Frame）之內容以計算出當前訊框與前一訊框之影像特徵值並進行比對，以及根據比對結果調整計數值，其調整方式如：當比對結果相符時，遞減此計數值，當比對結果不符時，遞增此計數值。在實際實施上，除了直接將兩個訊框（當前訊框及前一訊框）之影像特徵值進行比對外，還可計算兩個影像特徵值之差值的絕對值，當此絕對值大於零或一個預設值（例如：數值“10＂）時，遞增此計數值（例如：計數值加上數值“1＂），反之，當此絕對值未大於所述預設值時，遞減此計數值（例如：計數值減數值“1＂）。特別要說明的是，由於訊框之影像特徵值的計算方式為習知技術，故在此不再多作贅述。The image state-based energy-saving control system and the method thereof are further described below with reference to the drawings. Please refer to "FIG. 1" first, and "FIG. 1" is a system block diagram of the image state-based energy-saving control system of the present invention. The system includes: a detection module 110, a determination module 120, a selection module 130, and a control module 140. The detecting module 110 is configured to continuously detect the content of each frame of the image when the image is played, to calculate and compare the image feature values of the current frame and the previous frame, and according to The comparison result adjusts the count value, and the adjustment manner is as follows: when the comparison result is consistent, the count value is decremented, and when the comparison result does not match, the count value is incremented. In actual implementation, in addition to directly comparing the image feature values of the two frames (the current frame and the previous frame), the absolute value of the difference between the two image feature values may be calculated, when the absolute value is greater than When zero or a preset value (for example, the value "10"), increment this count value (for example: count value plus the value "1"), otherwise, when this absolute value is not greater than the preset value, decrement this The count value (for example, the count value minus the value "1"). In particular, since the calculation method of the image feature value of the frame is a conventional technique, it will not be repeated here.
判斷模組120用以在此計數值大於動態門檻值時，將影像的狀態設定為動態，並且直到此計數值小於靜態門檻值時，才將影像的狀態切換為靜態。由於動態門檻值及靜態門檻值已於前述自行定義名詞中作說明，故在此不再多作贅述。另外，以上述調整方式為例，假設動態門檻值為數值“9＂、靜態門檻值為數值“1＂，當計數值為數值“10＂時，判斷模組120會因為計數值大於動態門檻值“9＂而將影像的狀態設為動態，倘若根據影像的連續幾個訊框之內容所計算出的影像特徵值皆相同時，偵測模組110會持續因比對結果相符而逐次遞減計數值，當計數值持續遞減至小於靜態門檻值“1＂時，便將影像狀態切換為靜態。如此一來，即可避免在短時間內使影像狀態在靜態與動態間反覆切換。The determining module 120 is configured to set the state of the image to be dynamic when the count value is greater than the dynamic threshold, and switch the state of the image to static until the count value is less than the static threshold. Since the dynamic threshold and the static threshold are described in the above-mentioned self-defined nouns, they will not be repeated here. In addition, taking the above adjustment method as an example, assuming that the dynamic threshold value is a value of “9” and the static threshold value is a value “1”, when the count value is a value “10”, the determination module 120 may be greater than the dynamic threshold value because the count value is greater than the dynamic threshold value. "9" and the state of the image is set to be dynamic. If the image feature values calculated according to the contents of consecutive frames of the image are the same, the detection module 110 continues to successively decrease the count due to the matching result. The value, when the count value continues to decrease to less than the static threshold value of "1", the image state is switched to static. In this way, it is possible to avoid the image state being repeatedly switched between static and dynamic in a short time.
選擇模組130用以在影像的狀態為動態時，選擇適用於動態影像的節能控制方式，在影像的狀態為靜態時，自禁能電路及停止在記憶體中更新影像的節能控制方式中選擇至少其中之一，所述記憶體包含暫存器、快取記憶體及隨機存取記憶體等等。在實際實施上，所述禁能電路包含禁能適用於動態影像且耗電量大的電路以及禁能影像分析統計的電路，由於動態影像需要較複雜且耗電的電路進行處理，所以當影像的狀態為靜態時，禁能此部分的電路而僅採用針對靜態影像的電路將可有效達到節能的效果。另外，由於靜態影像的影像資料不會變化，所以不需如動態影像需要更新記憶體中的影像資料，因此，選擇模組130亦可選擇停止在記憶體中更新影像的節能控制方式，如此一來，便可節省將資料寫入記憶體中所產生的功耗。在實際實施上，除了選擇上述的節能控制方式之外，還可搭配動態背光調整技術（Content Adaptive Brightness Control, CABC），根據影像的內容調整背光的亮度，以便節省功率消耗，由於動態背光調整技術為習知技術，故在此不再多作贅述。The selection module 130 is configured to select an energy-saving control mode suitable for the motion image when the state of the image is dynamic, and select the self-blocking circuit and the energy-saving control mode for stopping updating the image in the memory when the state of the image is static. In at least one of the memories, the memory includes a scratchpad, a cache memory, a random access memory, and the like. In practical implementation, the disable circuit includes a circuit for disabling a dynamic image and a large power consumption, and a circuit for disabling image analysis and statistics. Since the dynamic image requires a complicated and power-consuming circuit to process, when the image is processed, the image is disabled. When the state is static, disabling the circuit of this part and using only the circuit for static images can effectively achieve the effect of energy saving. In addition, since the image data of the still image does not change, it is not necessary to update the image data in the memory as the moving image. Therefore, the selection module 130 can also select an energy-saving control method for stopping the updating of the image in the memory, such that This saves the power generated by writing data into the memory. In actual implementation, in addition to the above-mentioned energy-saving control mode, it can also be combined with Dynamic Adaptive Brightness Control (CABC) to adjust the brightness of the backlight according to the content of the image, so as to save power consumption, due to dynamic backlight adjustment technology. It is a conventional technique, so it will not be repeated here.
控制模組140用以切換為選擇模組130選擇的節能控制方式以顯示影像。舉例來說，假設選擇模組130選擇適用於動態影像的節能控制方式，那麼在影像狀態未改變為靜態之前，將持續以此動態影像的節能控制方式顯示影像；假設選擇模組130在禁能電路及停止在記憶體中更新影像的節能控制方式中選擇至少其中之一，那麼，在影像狀態未改變為動態之前，同樣會持續以此節能控制方式顯示影像。The control module 140 is configured to switch to the energy saving control mode selected by the selection module 130 to display an image. For example, if the selection module 130 selects an energy-saving control mode suitable for a dynamic image, the image is continuously displayed in the energy-saving control mode of the dynamic image before the image state is changed to static; Selecting at least one of the circuit and the energy-saving control method for stopping updating the image in the memory, the image is continuously displayed in this energy-saving control mode until the image state is changed to dynamic.
接著，請參閱「第2圖」，「第2圖」為本發明基於影像狀態的節能控制方法，其步驟包括：在播放影像時，持續偵測影像的每一訊框之內容以計算出當前訊框與前一訊框之影像特徵值並進行比對，以及根據比對結果調整計數值（步驟210）；在計數值大於動態門檻值時，將影像的狀態設定為動態，並且直到此計數值小於靜態門檻值時，將影像的狀態切換為靜態（步驟220）；在影像的狀態為動態時，選擇適用於動態影像的節能控制方式，在影像的狀態為靜態時，自禁能電路及停止在記憶體中更新該影像的節能控制方式中選擇至少其中之一（步驟230）；切換為選擇的節能控制方式以顯示此影像（步驟240）。透過上述步驟，即可透過持續偵測影像的每一訊框之內容以計算出當前訊框與前一訊框之影像特徵值並進行比對，並且根據比對結果調整計數值，當計數值大於動態門檻值時，選擇動態的節能控制方式，當計數值小於靜態門檻值時，自禁能電路及停止在記憶體中更新影像的節能控制方式中選擇至少其中之一，以便使用選擇的節能控制方式來顯示影像。Next, please refer to "2nd picture", "2nd picture" is the image state-based energy-saving control method of the present invention, the steps include: continuously detecting the content of each frame of the image to calculate the current when playing the image The frame is compared with the image feature value of the previous frame, and the count value is adjusted according to the comparison result (step 210); when the count value is greater than the dynamic threshold value, the state of the image is set to dynamic, and up to this count When the value is less than the static threshold, the state of the image is switched to static (step 220); when the state of the image is dynamic, the energy-saving control mode suitable for the dynamic image is selected, and when the state of the image is static, the self-blocking circuit and At least one of the energy saving control modes for stopping updating the image in the memory is selected (step 230); switching to the selected energy saving control mode to display the image (step 240). Through the above steps, the image feature values of the current frame and the previous frame can be calculated and compared by continuously detecting the content of each frame of the image, and the count value is adjusted according to the comparison result, and the count value is When the value is greater than the dynamic threshold, the dynamic energy-saving control mode is selected. When the count value is less than the static threshold, at least one of the disable circuit and the energy-saving control mode for updating the image in the memory is selected to use the selected energy-saving. Control mode to display images.
另外，在步驟210更可計算所述影像特徵值的差值之絕對值，當所述絕對值大於零或預設值時，遞增此計數值，當所述絕對值未大於所述預設值時，遞減此計數值，其中此計數值在預設範圍內遞增或遞減（步驟215）。其中，當絕對值大於零代表當前訊框與前一訊框之內容（即像素）存在差異，而所述預設值則代表此差異的容許範圍。舉例來說，假設預設值設為“10＂可代表允許當前訊框與前一訊框存在十個不同的像素並視為相同的訊框。In addition, in step 210, the absolute value of the difference of the image feature values may be further calculated. When the absolute value is greater than zero or a preset value, the count value is incremented, when the absolute value is not greater than the preset value. At this time, the count value is decremented, wherein the count value is incremented or decremented within a preset range (step 215). Wherein, when the absolute value is greater than zero, the current frame is different from the content of the previous frame (ie, the pixel), and the preset value represents the allowable range of the difference. For example, assuming that the preset value is set to "10", it means that the current frame and the previous frame have ten different pixels and are regarded as the same frame.
以下配合「第3圖」及「第4圖」以實施例的方式進行如下說明，請先參閱「第3圖」，「第3圖」為本發明計數值在預設範圍內之示意圖。在實際實施上，計數值可限定在一個預設範圍內遞增或遞減，此預設範圍包含預先設定的上限數值及下限數值，當遞增計數值到達預設範圍上限時，倘若要再次進行遞增，則計數值將維持在上限數值不變，反之，當遞減計數值到達預設範圍下限時，倘若要再次進行遞減，則計數值將維持在下限數值不變。換句話說，計數值不會超出預設範圍，以避免計數值過大或過小而導致發生不可預期的錯誤。以此例而言，所述預設範圍內包含動態門檻值和靜態門檻值，其中，動態門檻值靠近預設範圍上限；靜態門檻值則靠近預設範圍下限。The following description will be made by way of example with reference to "Fig. 3" and "Fig. 4". Please refer to "Fig. 3" first, and "Fig. 3" is a schematic diagram showing the count value of the present invention within a preset range. In actual implementation, the count value may be limited to be incremented or decremented within a preset range, and the preset range includes a preset upper limit value and a lower limit value. When the count value reaches the upper limit of the preset range, if the increment is to be performed again, Then, the count value will remain unchanged at the upper limit value. Conversely, when the countdown value reaches the lower limit of the preset range, if the decrement is to be performed again, the count value will remain unchanged at the lower limit value. In other words, the count value does not exceed the preset range to prevent the count value from being too large or too small to cause an unexpected error. In this example, the preset range includes a dynamic threshold value and a static threshold value, wherein the dynamic threshold value is close to the upper limit of the preset range; and the static threshold value is close to the lower limit of the preset range.
如「第4圖」所示意，「第4圖」為應用本發明的節能控制之示意圖。在實際實施上，可以將計數器的初始值設為“10＂、動態門檻值設為“9＂、靜態門檻值設為“1＂，在不同時間點的當前訊框與前一訊框之影像特徵值進行比對後，若比對結果相同則計數值遞減，當多次比對且遞減直到數值為“0＂時，判斷模組120會判斷計數值小於靜態門檻值，所以將影像的狀態切換為靜態，接著，選擇模組130可選擇停止在記憶體中更新影像，或是禁能處理動態影像的相關電路以便節省電力，或同時選擇前述兩者，以便控制模組140切換為選擇模組130選擇的節能控制方式來顯示影像。然後，在當前訊框與前一訊框之影像特徵值的比對結果為不同時，計數值遞增，並且在計數值遞增至數值“10＂時，判斷模組120因計數值大於動態門檻值“9＂而將影像的狀態切換為動態。也就是說，雖然訊框已改變，但是在持續改變的次數未滿足動態門檻值的情況下，仍然維持使用靜態影像的節能控制方式，反之亦然。As shown in "Fig. 4", "Fig. 4" is a schematic diagram of energy saving control to which the present invention is applied. In actual implementation, the initial value of the counter can be set to "10", the dynamic threshold value is set to "9", and the static threshold value is set to "1". The image of the current frame and the previous frame at different time points. After the eigenvalues are compared, if the comparison result is the same, the count value is decremented. When the comparison is repeated and the value is "0" until the value is "0", the judgment module 120 determines that the count value is smaller than the static threshold value, so the state of the image is Switching to static, then, the selection module 130 can choose to stop updating the image in the memory, or disable the related circuit of the dynamic image to save power, or select both of the above, so that the control module 140 switches to the selection mode. The energy saving control mode selected by the group 130 displays an image. Then, when the comparison result of the image feature values of the current frame and the previous frame is different, the count value is incremented, and when the count value is incremented to the value “10”, the determination module 120 is greater than the dynamic threshold value due to the count value. "9" switches the state of the image to dynamic. That is to say, although the frame has changed, the power saving control mode using the still image is maintained while the number of continuous changes does not satisfy the dynamic threshold, and vice versa.
綜上所述，可知本發明與先前技術之間的差異在於透過持續偵測影像的每一訊框之內容以計算出當前訊框與前一訊框之影像特徵值並進行比對，並且根據比對結果調整計數值，當計數值大於動態門檻值時，選擇動態的節能控制方式，當計數值小於靜態門檻值時，自禁能電路及停止在記憶體中更新影像的節能控制方式中選擇至少其中之一，以便使用選擇的節能控制方式來顯示影像，藉由此一技術手段可以解決先前技術所存在的問題，進而達成以影像狀態選擇執行相應的節能控制方式來提高顯示裝置的節能效率之技術功效。In summary, it can be seen that the difference between the present invention and the prior art is that the content of each frame of the current frame and the previous frame are calculated and compared by continuously detecting the content of each frame of the image, and according to The comparison result adjusts the count value. When the count value is greater than the dynamic threshold value, the dynamic energy-saving control mode is selected. When the count value is less than the static threshold value, the self-blocking circuit and the energy-saving control mode for stopping updating the image in the memory are selected. At least one of them is used to display an image by using the selected energy-saving control mode, and the technical problem can solve the problems existing in the prior art, thereby achieving the selection of the corresponding energy-saving control mode by the image state to improve the energy-saving efficiency of the display device. Technical efficacy.
