在現今資訊爆炸的時代裡，人類生活已經離不開電子通訊，人與人之間經常運用電子通訊裝置來互相傳遞訊息已經是相當普遍，尤其是可以隨身攜帶的可攜式電子裝置，例如行動電話或具有無線通訊功能之電子裝置。In today's era of information explosion, human life is inseparable from electronic communication.

A telephone or an electronic device with wireless communication capabilities.
在行動通訊技術日益發達的今日，行動通訊裝置的功能仍不斷地推陳出新。除了收聽廣播等功能以外，目前有許多行動通訊裝置更發展出具有照相功能，故當使用者想要照相留念時，可利用具有照相功能之行動通訊裝置來拍攝數位影像。然而，所拍攝的數位影像的好壞，除了行動通訊裝置所配備的相機鏡頭的優劣外，相機的影像擷取技術更是不可忽視。Today, mobile communication technology is increasingly developed, and the functions of mobile communication devices are constantly being introduced. In addition to listening to broadcast and other functions, many mobile communication devices have developed camera functions, so when users want to take pictures, they can use digital camera communication devices to take digital images.

為讓本發明之上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。The above described features and advantages of the present invention will be more apparent from the following description.
圖1是依照本發明一實施例的一種影像擷取系統的示意簡圖。請參照圖1，本實施例的影像擷取系統，適用於一可攜式裝置100(請參照圖2)。其中可攜式裝置100例如是個人數位助理(personal digital assistant，PDA)、PDA手機、智慧型手機或是觸控式手機。另外，可攜式裝置100配置有一透鏡組102。1 is a schematic diagram of an image capture system in accordance with an embodiment of the invention. Referring to FIG. 1, the image capturing system of this embodiment is applicable to a portable device 100 (please refer to FIG. 2). The portable device 100 is, for example, a personal digital assistant (PDA), a PDA mobile phone, a smart phone, or a touch mobile phone. In addition, the portable device 100 is configured with a lens group 102.
此影像擷取系統包括動作感應模組104、透鏡位置設定模組106、透鏡驅動器108以及影像擷取單元110。The image capturing system includes a motion sensing module 104, a lens position setting module 106, a lens driver 108, and an image capturing unit 110.
動作感應模組104感應一影像擷取動作以及影像擷取動作的一動作時間。也就是當使用者在可攜式裝置100上產生一影像擷取動作，包括以手指按壓代表擷取影像的實體按鍵或是顯示於觸控螢幕上的虛擬按鍵時，產生一影像擷取動作，而動作感應模組104感應此影像擷取動作以及其動作時間。更明確的說，此動作時間例如是影像擷取動作從開始至動作完成的一動作期間。The motion sensing module 104 senses an image capturing motion and an action time of the image capturing motion. That is, when the user generates an image capturing action on the portable device 100, including pressing a physical button representing the captured image or a virtual button displayed on the touch screen with a finger, an image capturing action is generated. The motion sensing module 104 senses the image capturing action and its action time. More specifically, the action time is, for example, an action period from the start of the image capture operation to the completion of the action.
透鏡位置設定模組106根據動作感應模組104所感應的動作時間，決定對所拍攝實體對焦的透鏡組102的透鏡位置(lens position)。再者，透鏡驅動器108驅動透鏡組102至影像擷取透鏡位置。而影像擷取單元110，進行一影像擷取。The lens position setting module 106 determines a lens position of the lens group 102 that focuses on the captured entity based on the operation time sensed by the motion sensing module 104. Furthermore, lens driver 108 drives lens group 102 to the image capture lens position. The image capturing unit 110 performs an image capture.
也就是，當動作時間大於等於透鏡組102根據影像擷取動作而進行的一對焦掃描的一對焦掃描時間時，則透鏡位置設定模組106以對焦掃描所決定的透鏡位置為影像擷取透鏡位置。另一方面，當動作時間小於對焦掃描時間時，則以預設透鏡位置為影像擷取透鏡位置。That is, when the action time is greater than or equal to a focus scan time of a focus scan performed by the lens group 102 according to the image capture operation, the lens position setting module 106 uses the lens position determined by the focus scan as the image capture lens position. . On the other hand, when the action time is less than the focus scan time, the lens position is taken as the image with the preset lens position.
更明確的說，當使用者在可攜式裝置100上產生影像擷取動作時，則觸動透鏡驅動器108對於所欲拍攝的實體進行對焦掃描。一般而言，對焦掃描過程中，透鏡組102經由透鏡驅動器108沿著光學軸前後移動，直到拍攝實體的影像於影像擷取元件(image-capturing element，例如電荷耦合元件，charge-coupled device(CCD))上成像所產生的影像擷取訊號的頻率最大時，此時透鏡組的位置則在最佳透鏡位置，而拍攝實體則位於此透鏡組的焦距位置。亦即，當調整透鏡組位置，使得拍攝實體位於透鏡組的焦距位置時，所擷取的拍攝實體的影像則最清晰。然而，經由透鏡驅動器108驅動透鏡組102沿著光學軸前後移動找到最佳透鏡位置，則需要耗費一對焦掃描時間。More specifically, when the user generates an image capturing action on the portable device 100, the lens driver 108 is activated to perform a focus scan on the entity to be photographed. In general, during the focus scan, the lens group 102 moves back and forth along the optical axis via the lens driver 108 until the image of the photographing entity is image-capturing element (such as a charge-coupled device). )) When the frequency of the image capturing signal generated by the upper imaging is the largest, the position of the lens group is at the optimal lens position, and the shooting entity is located at the focal length of the lens group. That is, when the lens group position is adjusted such that the photographing entity is located at the focal length position of the lens group, the captured image of the photographing entity is the clearest. However, driving the lens group 102 back and forth along the optical axis via the lens driver 108 to find the optimum lens position requires a focus scan time.
因此，當使用者在可攜式裝置100上產生影像擷取動作時，其動作時間大於透鏡組102所需的對焦掃描時間時，則透鏡位置設定模組106則在完成對焦掃描後，以對焦掃描所決定的透鏡位置(亦即相對應於最佳焦距位置的最佳透鏡位置)做為影像擷取透鏡位置。Therefore, when the user generates an image capturing action on the portable device 100, and the action time is greater than the focus scan time required by the lens group 102, the lens position setting module 106 focuses after the focus scan is completed. The position of the lens determined by the scan (i.e., the optimum lens position corresponding to the optimum focal length position) is taken as the image capturing lens position.
然而，當使用者急壓可攜式裝置100上代表擷取影像的實體按鍵或是顯示於觸控螢幕上的虛擬按鍵，造成動作時間小於透鏡組102所需的對焦掃描時間時，則透鏡位置設定模組106立即以預設透鏡位置為影像擷取透鏡位置。於一實施例中，此預設透鏡位置所對應的焦距位置例如為100~200公分。於另一實施例中，此預設透鏡位置例如為使用者的慣用透鏡位置。However, when the user presses the physical button on the portable device 100 to represent the captured image or the virtual button displayed on the touch screen, causing the action time to be less than the focus scan time required by the lens group 102, the lens position The setting module 106 immediately captures the lens position with the preset lens position as the image. In an embodiment, the focal length position corresponding to the preset lens position is, for example, 100 to 200 cm. In another embodiment, the predetermined lens position is, for example, a user's conventional lens position.
更明確的說，影像擷取系統，還包括一記錄模組(未繪示)以及一統計模組(未繪示)。記錄模組記錄每次使用者使用可攜式裝置100近行影像擷取的影像擷取透鏡位置。而統計模組統計所記錄的影像擷取透鏡位置以獲得使用者常用的慣用透鏡位置，並提供此慣用透鏡位置給透鏡位置設定模組106做為預設透鏡位置。也就是不同使用者，在拍攝不同實體時，通常有個人使用的慣性，例如喜歡被拍攝實體於擷取影像中是全景或是半身，甚至只是頭像。藉由統計使用者的每次影像擷取時的透鏡位置，可以計算出使用者的影降擷取慣性，進而可以推估出最適於使用者在進行影像擷取時的透鏡位置，並以此透鏡位置為預設透鏡位置。More specifically, the image capture system further includes a recording module (not shown) and a statistical module (not shown). The recording module records the image capturing position of the image captured by the user using the near-line image of the portable device 100. The image recorded by the statistical module statistic captures the lens position to obtain the usual lens position commonly used by the user, and provides the conventional lens position to the lens position setting module 106 as a preset lens position. That is to say, different users, when shooting different entities, usually have the inertia of personal use, for example, like the captured entity in the captured image is a panorama or a half body, or even just an avatar. By counting the lens position of each user's image capture, the user's shadow drop extraction inertia can be calculated, and the lens position that is most suitable for the user to perform image capture can be estimated. The lens position is a preset lens position.
因此，當使用者在可攜式裝置100上產生的影像擷取動作的動作時間小於對焦掃描時間時，即便是拍攝實體並非位在預設透鏡位置所對應的對焦位置，由於預設透鏡位置為使用者的慣用透鏡位置，因此拍攝實體位於焦距位置的景深範圍內的機率提高，所以所擷取的影像清晰度則在一可容忍範圍內。如此一來，無需耗時等待對焦掃描，本發明的影像擷取系統可以快速反應使用者的影像擷取動作，大幅縮短影像擷取動作與快門啟動之間的時間差。Therefore, when the operation time of the image capturing action generated by the user on the portable device 100 is less than the focus scanning time, even if the shooting entity is not at the focus position corresponding to the preset lens position, the preset lens position is The user's usual lens position, so the probability that the shooting entity is within the depth of field of the focal length position is increased, so the image sharpness captured is within a tolerable range. In this way, the image capturing system of the present invention can quickly respond to the user's image capturing action without greatly waiting for the focus scan, and greatly shorten the time difference between the image capturing action and the shutter activation.
圖2是依照本發明一實施例的一種影像擷取方法的流程簡圖。請參照圖2，本實例的影像擷取方法是用於可攜式裝置(如圖1的可攜式裝置100)，可攜式裝置配置有一透鏡組(如圖1的透鏡組102)。於步驟S201中，感應影像擷取動作以及影像擷取動作的一動作時間。之後，於步驟S205中，比對動作時間與進行對焦掃描所需的對焦掃描時間。FIG. 2 is a schematic flow chart of an image capture method according to an embodiment of the invention. Referring to FIG. 2, the image capturing method of the present example is for a portable device (such as the portable device 100 of FIG. 1), and the portable device is configured with a lens group (such as the lens group 102 of FIG. 1). In step S201, an image capture operation and an action time of the image capture operation are sensed. Thereafter, in step S205, the operation time is compared with the focus scan time required for the focus scan.
當動作時間大於等於透鏡組根據影像擷取動作而進行的對焦掃描的對焦掃描時間時，則以對焦掃描所決定的透鏡位置為影像擷取透鏡位置(步驟S211)。When the operation time is greater than or equal to the focus scan time of the focus scan by the lens group according to the image capture operation, the lens position determined by the focus scan is the image capture lens position (step S211).
當該動作時間小於對焦掃描時間，則以預設透鏡位置為影像擷取透鏡位置(步驟S215)。接著，進行一影像擷取，其中透鏡組位於該影像擷取透鏡位置(步驟S221)。When the action time is less than the focus scan time, the lens position is captured as the image with the preset lens position (step S215). Next, an image capture is performed, wherein the lens group is located at the image capturing lens position (step S221).
值得注意的是，於感應影像擷取動作之後，還包括根據所感應的影像擷取動作，進行對焦掃描。另外，前述預設透鏡位置例如是經由記錄每次使用者進行影像擷取時的影像擷取透鏡位置。統計所記錄的影像擷取透鏡位置以獲得使用者的慣用透鏡位置，並以此慣用透鏡位置為預設透鏡位置。It is worth noting that after the sensing image capture operation, the focus scan is performed according to the sensed image capture action. In addition, the preset lens position is, for example, an image capturing lens position by recording each time the user performs image capturing. The recorded image captures the lens position to obtain the user's usual lens position, and the conventional lens position is the preset lens position.
於前述有關於影像擷取系統的實施例中，已經詳述根據使用者在可攜式裝置上所產生的影像擷取動作的型態(也就是動作時間的長短)，決定影像擷取時的透鏡位置(換句話說就是影像擷取時的焦距位置)的概念，因此於本實施例中不再此進行贅述。此外，本發明的影像擷取系統可經由執行一電腦可讀取程式而具體實行。而此電腦可讀取程式可儲存於電腦可讀寫儲存媒體(未繪示)中，並且藉由可攜式裝置的處理器執行此電腦可讀取程式的指令以具體實行本發明的影像擷取系統與影像擷取方法。In the foregoing embodiment of the image capturing system, the type of image capturing operation (that is, the length of the action time) generated by the user on the portable device has been described in detail, and the image capturing time is determined. The concept of the lens position (in other words, the position of the focal length at the time of image capture) is not described in this embodiment. Furthermore, the image capture system of the present invention can be embodied by executing a computer readable program. The computer readable program can be stored in a computer readable and writable storage medium (not shown), and the computer readable program can be executed by the processor of the portable device to implement the image of the present invention. Take the system and image capture method.
本發明中，當使用者於可攜式裝置上產生一影像擷取動作時，可攜式裝置根據使用者產生影像擷取動作的模式(亦即動作時間長短)，自動設定透鏡組的透鏡位置是預設透鏡位置，還是根據對焦掃描結果而決定的相對應於最佳焦距位置的最佳透鏡位置(亦即影像擷取透鏡位置)。由於預設透鏡位置是以一般大眾在拍攝影像時所常用的透鏡位置為可攜式裝置出廠預設值，或是以分析使用者慣用透鏡位置記錄決定的客製化透鏡位置。如此一來，當使用者急於擷取動態實體的影像時，使用者的急壓快門所產生的影像擷取動作，可觸動可攜式裝置的透鏡組直接以預設透鏡位置進行動態實體的影像擷取，而預設透鏡位置所對應的焦距位置為使用者常用的焦距位置，致使被拍攝實體位於焦距位置的景深範圍內的機率提高，因此所擷取的影像清晰度則在一可容忍範圍內。所以，無須耗費時間等待對焦掃描，可攜式裝置可以快速反應使用者的影像擷取動作，縮短快門啟動與影像擷取動作產生時的時間差。In the present invention, when the user generates an image capturing operation on the portable device, the portable device automatically sets the lens position of the lens group according to the mode in which the user generates the image capturing action (ie, the length of the action time). Whether it is the preset lens position or the optimal lens position (ie, the image capturing lens position) corresponding to the optimal focal length position determined according to the result of the focus scan. The preset lens position is the preset position of the portable device when the image is commonly used by the general public to capture the image, or the position of the customized lens determined by analyzing the user's conventional lens position record. In this way, when the user is eager to capture the image of the dynamic entity, the image capturing action generated by the user's sudden pressure shutter can touch the lens group of the portable device to directly perform the image of the dynamic entity with the preset lens position. The focus position corresponding to the preset lens position is the focal position commonly used by the user, so that the probability that the captured entity is within the depth of field of the focal length position is increased, so that the captured image clarity is within a tolerable range. Inside. Therefore, the portable device can quickly respond to the user's image capturing action without delaying the focus scanning, and shorten the time difference between the shutter start and the image capturing action.
