參閱圖1所示，為本發明較佳實施例的電子裝置100的功能模組圖。 該電子裝置可為行動電話、平板電腦及個人數位助理等。 1 is a functional block diagram of an electronic device 100 in accordance with a preferred embodiment of the present invention. The electronic device can be a mobile phone, a tablet computer, and a personal digital assistant.

該電子裝置100包括鏡頭模組10、影像感測器20、對焦模組30、處理器40以及記憶體50。該鏡頭模組10、影像感測器20、對焦模組30以及記憶體50均與該處理器40相連。 The electronic device 100 includes a lens module 10 , an image sensor 20 , a focus module 30 , a processor 40 , and a memory 50 . The lens module 10, the image sensor 20, the focus module 30, and the memory 50 are all connected to the processor 40.

在本較佳實施例中，該鏡頭模組10包括標準鏡頭11、遠距鏡頭13及微距鏡頭12。該標準鏡頭11為一般鏡頭裝置，用於進行一般距離拍攝。該遠距鏡頭13及微距鏡頭12分別用於遠距及微距拍攝。遠距鏡頭13的視角比標準鏡頭11的視角更窄。 In the preferred embodiment, the lens module 10 includes a standard lens 11, a distance lens 13 and a macro lens 12. The standard lens 11 is a general lens device for general distance shooting. The telephoto lens 13 and the macro lens 12 are used for remote and macro photography, respectively. The angle of view of the telephoto lens 13 is narrower than that of the standard lens 11.

該影像感測器20用於通過上述的標準鏡頭11、遠距鏡頭13或微距鏡頭12獲取拍攝目標的畫面。 The image sensor 20 is configured to acquire a picture of a shooting target through the standard lens 11, the distance lens 13 or the macro lens 12 described above.

該對焦模組30用於控制上述多個鏡頭，即標準鏡頭11、遠距鏡頭13及微距鏡頭12進行自動對焦以獲得清晰的畫面。該對焦模組30包括聲音線圈馬達31，用於驅動上述鏡頭對焦。 The focusing module 30 is configured to control the plurality of lenses, that is, the standard lens 11, the distance lens 13 and the macro lens 12 to perform auto focusing to obtain a clear picture. The focus module 30 includes a voice coil motor 31 for driving the lens to focus.

Focus distance, preset conditions for picture quality, preset values for crop ratio, etc.

如圖2所示，本發明鏡頭切換方法較佳實施方式的流程圖。該鏡頭切換方法由處理器40執行並包括以下步驟。所述較佳實施方式也是本發明的較佳實施例。根據不同的需求，該圖所示流程圖中的執行順序可以改變，某些可以省略。 2 is a flow chart of a preferred embodiment of the lens switching method of the present invention. The shot switching method is performed by the processor 40 and includes the following steps. The preferred embodiment is also a preferred embodiment of the invention. The order of execution in the flowchart shown in the figure may vary depending on various requirements, and some may be omitted.

步驟300，該處理器40選擇該標準鏡頭11作為當前鏡頭。可以理解，該電子裝置100可預設將該標準鏡頭作為當前鏡頭，則該步驟可省略。 In step 300, the processor 40 selects the standard lens 11 as the current lens. It can be understood that the electronic device 100 can preset the standard lens as the current lens, and the step can be omitted.

步驟301，該處理器40通過該對焦模組30在多個不同時間取得多個對焦距離。對焦距離就是鏡頭模組10與拍攝目標之間的距離。例如，在第一時間對應獲取第一對焦距離，在第二時間對應獲取第二對焦距離，其中，第二時間晚於第一時間。 In step 301, the processor 40 obtains a plurality of focus distances through the focus module 30 at a plurality of different times. The focusing distance is the distance between the lens module 10 and the shooting target. For example, the first focus distance is acquired correspondingly at the first time, and the second focus distance is acquired correspondingly at the second time, wherein the second time is later than the first time.

本較佳實施例中，該對焦模組30可通過三種方式其中的至少一種來獲取該對焦距離：第一種方式為鐳射測距；第二種方式為根據該影像感測器20獲取的影像畫面中的物件邊緣清晰度來估計對焦距離；第三種方式為通過該鏡頭模組10其中兩個鏡頭取得畫面景深，並利用景深來估計對焦距離。 In the preferred embodiment, the focusing module 30 can obtain the focusing distance by using at least one of three ways: the first mode is laser ranging; the second mode is the image acquired according to the image sensor 20. The edge of the object in the picture is used to estimate the focus distance; the third way is to obtain the depth of field through the two lenses of the lens module 10, and use the depth of field to estimate the focus distance.

步驟302，該處理器40比較第二時間對應的第二對焦距離與第一時間對應的第一對焦距離的大小關係，如果第二對焦距離小於第一對焦距離，則表明當前對焦距離逐漸縮小，用戶正在進行較近距離拍攝，進入步驟303，該處理器40需判斷該當前鏡頭是否適合當前距離拍攝，是否需要將當前鏡頭切換為微距鏡頭12。如果第二對焦距離大於第一對焦距離，則表明當前對焦距離逐漸增大，用戶正在進行較遠距離拍攝，則進入步驟306，該處理器40需判斷該標準鏡頭11是否適合當前距離拍攝，是否需要將當前鏡頭切換為遠距鏡頭13。 Step 302: The processor 40 compares the magnitude relationship between the second focus distance corresponding to the second time and the first focus distance corresponding to the first time. If the second focus distance is smaller than the first focus distance, the current focus distance is gradually reduced. The user is taking a closer shot. In step 303, the processor 40 needs to determine whether the current lens is suitable for the current distance shooting, and whether the current lens needs to be switched to the macro lens 12. If the second focus distance is greater than the first focus distance, it indicates that the current focus distance is gradually increasing, and the user is performing long distance shooting, then the process proceeds to step 306, and the processor 40 needs to determine whether the standard lens 11 is suitable for the current distance shooting, whether It is necessary to switch the current lens to the telephoto lens 13.

步驟303，該處理器40判斷當前鏡頭所拍攝畫面的品質是否滿足預設條件，如果當前鏡頭所拍攝畫面的品質滿足預設條件，則表明當前鏡頭仍能滿足用戶拍攝要求，無需切換當前鏡頭，返回至步驟302。如果當前鏡頭所拍攝畫面的品質不能滿足預設條件，則表明當前鏡頭可能不能夠滿足使用者拍攝要求，進入步驟304。在本較佳實施例中，該預設條件可以是當前鏡頭所拍攝畫面的對比度(contract)或清晰度(sharpness)大於第一預設值。 Step 303, the processor 40 determines whether the quality of the picture taken by the current lens meets the preset condition. If the quality of the picture taken by the current lens satisfies the preset condition, it indicates that the current lens can still satisfy the user's shooting requirement without switching the current lens. Return to step 302. If the quality of the picture taken by the current lens cannot satisfy the preset condition, it indicates that the current lens may not be able to satisfy the user's shooting requirement, and the process proceeds to step 304. In the preferred embodiment, the preset condition may be that the contrast or sharpness of the picture taken by the current lens is greater than the first preset value.

步驟304，該處理器40進一步判斷是否當前對焦距離已經到達該鏡頭模組10的對焦距離的下限值，如果已經到達該下限值，則表明已經無法通過自動對焦使得當前鏡頭獲得滿足預設條件的畫面，需切換至微距鏡頭12，因此，進入步驟305，如果未到達該下限值，則表明無需切換當前鏡頭，返回至步驟303，可通過自動對焦直至當前鏡頭獲得滿足預設條件的畫面。 Step 304, the processor 40 further determines whether the current focus distance has reached the lower limit value of the focus distance of the lens module 10, and if the lower limit value has been reached, it indicates that the current lens is not satisfied by the auto focus. The conditional picture needs to be switched to the macro lens 12, therefore, the process proceeds to step 305. If the lower limit value is not reached, it means that the current lens does not need to be switched, and the process returns to step 303, and the current lens can be obtained by the autofocus until the current lens is satisfied. Picture.

步驟305，該處理器40將當前鏡頭切換至該微距鏡頭12。 Step 305, the processor 40 switches the current lens to the macro lens 12.

步驟306，該處理器40判斷通過當前鏡頭所拍攝畫面的剪裁比率是否小於第二預設值，在步驟306中，該拍攝畫面是從影像感測器20所獲取的原始畫面剪裁出部分進行放大後得到，該剪裁比率定義為所述剪裁出的部份的面積與所述原始畫面的面積的比率。如果該剪裁比率大於或者等於第二預設值，則表明當前鏡頭仍然能夠滿足使用者需求，不需要切換當前鏡頭，返回至步驟302。如果該剪裁比率小於預設值，則表明當前鏡頭已經不能夠滿足使用者需求，進入步驟307。 Step 306, the processor 40 determines whether the clipping ratio of the picture taken by the current lens is smaller than the second preset value. In step 306, the shooting picture is the original picture clipping part obtained by the image sensor 20 and is enlarged. Thereafter, the crop ratio is defined as the ratio of the area of the cropped portion to the area of the original picture. If the clipping ratio is greater than or equal to the second preset value, it indicates that the current lens can still meet the user's needs, and the current lens does not need to be switched, and the process returns to step 302. If the clipping ratio is less than the preset value, it indicates that the current lens is no longer able to meet the user's needs, and proceeds to step 307.

步驟307，該處理器40將當前鏡頭切換至該遠距鏡頭13。 In step 307, the processor 40 switches the current lens to the telephoto lens 13.

步驟308，該影像感測器20通過當前鏡頭獲取拍攝目標的畫面。 Step 308, the image sensor 20 acquires a picture of the shooting target through the current lens.

本發明所述電子裝置100及其鏡頭切換方法可根據使用者拍攝的實際需求，自動將當前鏡頭切換為微距鏡頭12或者遠距鏡頭13，拍攝方便，且可保證所拍攝的畫面品質。 The electronic device 100 and the lens switching method thereof can automatically switch the current lens to the macro lens 12 or the remote lens 13 according to the actual needs of the user, and the shooting is convenient, and the picture quality can be ensured.
