請參閱第2A圖、第2B圖及第2C圖，其係為根據本發明實施例之閃光燈控制系統之第一示意圖、第二示意圖及第三示意圖。本實施例中係以智慧型手機作為行動裝置10來舉例實施，但不以此為限，行動裝置10亦可包含平板或一智慧型眼鏡。當使用者欲使用行動裝置10的主鏡頭模組13對外部景象37照相時，此時使用者只需先開啟安裝於行動裝置10上的影像擷取程式12，並利用一快門鍵36以執行此影像擷取程式12。Please refer to FIG. 2A, FIG. 2B and FIG. 2C, which are a first schematic diagram, a second schematic diagram and a third schematic diagram of a flashlight control system according to an embodiment of the invention. In the embodiment, the smart phone is used as the mobile device 10 as an example. However, the mobile device 10 may also include a tablet or a smart eyeglass. When the user wants to use the main lens module 13 of the mobile device 10 to take an image of the external scene 37, the user only needs to first open the image capturing program 12 mounted on the mobile device 10, and use a shutter button 36 to execute. This image capture program 12.
此影像擷取程式12係首先產生一控制指令31，並由主傳輸單元11透過傳輸控制協定(TCP/IP, Transmission Control Protocol / Internet Protocol)傳送此控制指令31至相機20之附屬傳輸單元21，其中此主傳輸單元11或附屬傳輸單元21係為一網路傳輸模組，控制指令31可包含對欲控制之附屬閃光燈23之一打閃強度值或一色溫值，其示意圖可見第2B圖。The image capturing program 12 first generates a control command 31, and the main transmission unit 11 transmits the control command 31 to the auxiliary transmission unit 21 of the camera 20 through a Transmission Control Protocol (TCP/IP, Transmission Control Protocol/Internet Protocol). The main transmission unit 11 or the auxiliary transmission unit 21 is a network transmission module, and the control command 31 may include a flashing intensity value or a color temperature value of the auxiliary flash 23 to be controlled, and the schematic diagram can be seen in FIG. 2B.
更進一步地說明，由於主傳輸單元11或附屬傳輸單元21係透過網路以進行溝通，因此行動裝置10與相機20可先執行一校正程序，以計算控制指令31由主傳輸單元11傳送至附屬傳輸單元21之一時間差，亦即包含此控制指令31之網路封包在網路上傳輸的時間，其實施方式可透過計算從主傳輸單元11傳送一個要求封包(request packet) 34到附屬傳輸單元21，並從附屬傳輸單元21傳送一個回覆封包(reply packet) 34至主傳輸單元11所需之時間再除以2，即為從主傳輸單元11傳送至附屬傳輸單元21之一時間差，其示意圖可見第2C圖。Further, since the main transmission unit 11 or the auxiliary transmission unit 21 communicates through the network, the mobile device 10 and the camera 20 can first execute a correction procedure to calculate that the control command 31 is transmitted from the main transmission unit 11 to the attachment. A time difference of the transmission unit 21, that is, the time when the network packet containing the control command 31 is transmitted over the network, the implementation may transmit a request packet 34 from the primary transmission unit 11 to the auxiliary transmission unit 21 by calculation. And the time required to transmit a reply packet 34 from the attached transmission unit 21 to the primary transmission unit 11 and then divide by 2, that is, a time difference from the primary transmission unit 11 to the secondary transmission unit 21, the schematic of which is visible Figure 2C.
附屬處理單元22接收到此控制指令31後，即可控制附屬閃光燈23打光以產生附屬參考光源。影像擷取程式12則控制主閃光燈14打光以產生一主參考光源，而根據先前求得之時間差，可使主閃光燈14與附屬閃光燈23同時進行打光，如此一來，主鏡頭模組13便可同時利用主參考光源及附屬參考光源以產生具較少陰暗部之一外部影像35。After receiving the control command 31, the accessory processing unit 22 can control the auxiliary flash 23 to be lighted to generate an auxiliary reference light source. The image capturing program 12 controls the main flash 14 to emit light to generate a main reference light source, and according to the previously determined time difference, the main flash 14 and the auxiliary flash 23 can be simultaneously illuminated, so that the main lens module 13 The primary reference source and the associated reference source can be utilized simultaneously to produce an external image 35 having fewer shades.
