Therefore, in step S402, the grouping unit 52 obtains two gray scale groups. They are bright gray-scale groups and dark gray-level groups. After the center of gravity unit 53 analyzes the center of gravity of the bright gray scale group of the captured image, the discriminating unit 60 can determine whether the center of gravity of the bright gray scale group is greater than the preset information PI, thereby determining whether the display 20 enters the power saving mode. When the center of gravity of the bright gray level group is greater than 220, it means that the display 20 enters the normal mode; otherwise, when the center of gravity of the bright gray level group is less than 22 inches,

In other words, as long as it is the test surface displayed by the simple display and it is judged by the image processing and analysis whether the display enters the power saving mode, it is in accordance with the spirit of the present invention. Several embodiments are exemplified below so that those skilled in the art can further develop the spirit of the invention and practice the invention. In the above embodiment, FIG. 3 and FIG. 4 are only the image processing unit and the process flow of the process, and the present invention is not limited thereto. The above embodiments can also be changed according to the needs of those skilled in the art. For example, FIG. 6 is a schematic diagram of another embodiment of the image processing unit of the wipes. FIG. 7 is a flow chart of another embodiment of step S202 of FIG. 2. 6 is similar to FIG. 3 except that FIG. 6 replaces the center of gravity unit 53 of FIG. 3 with a specific gravity unit 54. Steps S7()1 and S7()2 in Fig. 7 are similar to steps S401 and S402 in Fig. 4, and will not be described again. It is to be noted that, in step S7G3, the specific gravity unit 54 can analyze the proportion of the party gray scale and the dark gray scale. For example, the specific gravity unit 54 can illuminate the amount of gray ash according to the preset gray scale value. Predetermined in this embodiment. The gray I1 white value is, for example, 疋220. If the gray scale value of each element is greater than 22 (), it is determined that 201111973 PNAI-MI-0167-TWXX 32106twf.doc/n is a bright gray scale, and if the gray scale value of each element is less than 220, it is regarded as a dark gray level. The number of bright gray scales and dark gray scales can be counted to obtain the proportion of bright gray scales and dark gray scales.
接著，判別單元60可依據預設資訊PI與比重單元54 所統計的亮灰階數量來判別顯示器20是否進入省電模 式。在本實施例中’預設資訊PI例如是亮灰階的數量為 18%，熟習本領域技術者亦可依其需求改變預設資訊PI。 換言之’若判別單元60判別出亮灰階數量大於預設資訊 PI的18%，則可認定顯示器20進入正常模式；反之，若 判別單元60判別出亮灰階數量小於預設資訊？1的18%， 則可認定顯示器20進入省電模式。如此一來亦可達成與上 述實施例相類似的功效。 上述實施例中圖5 A的測試晝面TF僅是一種選擇實施 例，熟習本領域技術者亦可依其需求改變測試晝面TF。舉 例來說，《 SA是依照本發明的—實關的另—種測試影 像的示意圖。® 8B是依照本發明的一實施例的另一種測 試影像的長條圖。8C是依照本發明的另—實施例顯示 器在正常模式下’-種影像擷取單元所擷取的影像的長條 圖。在本實施例中，測試晝面TF是由8〇%的亮灰階與2〇 ΓΓί賴减。熟f本錢技術打、賊制試晝面 I改㈣綠訊PI，即可達成與上述實施例相類似的功 加以。一 施例。在另—實麵t，f彡像齡單 20所顯示的局部影像進行拍攝，如 也可對顯示器 例相類似的功效。 ’、可達成與上述實施 綜上所述，本發明可拍攝顯示器 並進行影像處理，轉得影像資訊。此試影像， 資訊與對應於測試晝面的預崎訊即可判別ί據^影像 入預設省驗式。此外本發日⑽實施例還具有進 1. 利用機n視覺來檢聰示器是 ^ I j ‘ Γ在省電模式下正常地顯i 地判別數位類比轉換器及/或其後端電:; 2. 檢測裝置在不接觸顯示器的情況下即對顯示器進 行檢測。 3·在環境光的強度不大的情況下，檢測裂置可正確地 檢測出顯示器是否進入省電模式。Next, the determining unit 60 can determine whether the display 20 enters the power saving mode according to the preset information PI and the number of bright gray levels counted by the specific gravity unit 54. In the present embodiment, the preset information PI is, for example, 18% of the number of bright gray levels. Those skilled in the art can also change the preset information PI according to their needs. In other words, if the discriminating unit 60 discriminates that the number of bright gray scales is greater than 18% of the preset information PI, it can be determined that the display 20 enters the normal mode; otherwise, if the discriminating unit 60 discriminates that the number of bright gray scales is smaller than the preset information? At 18% of 1, it can be assumed that the display 20 enters the power saving mode. In this way, effects similar to those of the above embodiments can be achieved. The test face TF of Fig. 5A in the above embodiment is only an alternative embodiment, and those skilled in the art can also change the test face TF according to the needs thereof. For example, "SA" is a schematic representation of another test image in accordance with the present invention. ® 8B is a bar graph of another test image in accordance with an embodiment of the present invention. 8C is a bar graph of an image captured by the image capturing unit in the normal mode in accordance with another embodiment of the present invention. In this embodiment, the test facet TF is reduced by 8〇% of the bright gray level and 2〇 ΓΓί. If you are familiar with the technology, you can make a similar function to the above embodiment. A case.

In addition, the embodiment of the present invention (10) also has the following: 1. The machine n vision is used to check that the smart device is ^ I j ' 正常 in the power saving mode, the digital analog converter and/or its back end power are normally recognized: 2. The detection device detects the display without touching the display. 3. In the case where the intensity of ambient light is not large, the detection of the split can correctly detect whether the display enters the power saving mode.
