圖2為根據本發明一實施例的影像結合方法的流程圖。 FIG. 2 is a flowchart of an image combining method according to an embodiment of the present invention.
請參照圖2，在步驟S201中，藉由第一電子裝置110拍攝第一影像，並從第二電子裝置120接收物體影像，其中第一電子裝置110具有第一橫向解析度及第一縱向解析度且第二電子裝置120具有第二橫向解析度及第二縱向解析度。舉例來說，圖3的第一影像300可由第一電子裝置110拍攝，第一影像300具有第一電子裝置110的第一橫向解析度Xa及第一縱向解析度Ya。圖4的第二影像400可由第二電子裝置120拍攝，第二影像400具有第二電子裝置120的第二橫向解析度Xb及第二縱向解析度Yb。在第二電子裝置120拍攝第二影像400之後，第二電子裝置120可利用任何去除背景的演算法將第二影像400的背景去除，以 產生一個物體影像500，如圖5所示，在此物體影像500的解析度與第二影像400相同。因此，第一電子裝置110就可從第二電子裝置120接收物體影像500。 Please refer to FIG. 2. In step S201, a first electronic device 110 captures a first image and receives an object image from a second electronic device 120. The first electronic device 110 has a first horizontal resolution and a first vertical resolution. The second electronic device 120 has a second horizontal resolution and a second vertical resolution. For example, the first image 300 of FIG. 3 can be captured by the first electronic device 110. The first image 300 has a first horizontal resolution Xa and a first vertical resolution Ya of the first electronic device 110. The second image 400 of FIG. 4 can be captured by the second electronic device 120. The second image 400 has a second horizontal resolution Xb and a second vertical resolution Yb of the second electronic device 120. After the second electronic device 120 captures the second image 400, the second electronic device 120 may remove the background of the second image 400 by using any background removal algorithm, so as to An object image 500 is generated. As shown in FIG. 5, the resolution of the object image 500 is the same as that of the second image 400. Therefore, the first electronic device 110 can receive the object image 500 from the second electronic device 120.
在步驟S203中，判斷第二縱向解析度與第一縱向解析度的第一縱向比值是否小於第二橫向解析度與第一橫向解析度的第一橫向比值。舉例來說，第一電子裝置110可判斷第一縱向比值Yb/Ya是否小於第一橫向比值Xb/Xa。 In step S203, it is determined whether a first longitudinal ratio of the second longitudinal resolution and the first longitudinal resolution is smaller than a first lateral ratio of the second lateral resolution and the first lateral resolution. For example, the first electronic device 110 may determine whether the first vertical ratio Yb / Ya is smaller than the first horizontal ratio Xb / Xa.
若第一縱向比值小於第一橫向比值，在步驟S205中，第一電子裝置110根據第一縱向比值縮放物體影像。 If the first vertical ratio is smaller than the first horizontal ratio, in step S205, the first electronic device 110 scales the image of the object according to the first vertical ratio.
若第一縱向比值大於第一橫向比值，在步驟S207中，第一電子裝置110根據第一橫向比值縮放物體影像。舉例來說，由於在本範例中，Yb大致等於Ya但Xb明顯小於Xa，因此第一電子裝置110會判斷Yb/Ya大於Xb/Xa，並根據Xb/Xa來縮放物體影像500。在本範例中，第一電子裝置110會將物體影像500的第二橫向解析度Xb及第二縱向解析度Yb分別除以Xb/Xa以獲得縮放後的物體影像600，如圖6所示。因此縮放後的物體影像600的橫向解析度為Xa，且縱向解析度為Yb*Xa/Xb。 If the first vertical ratio is greater than the first horizontal ratio, in step S207, the first electronic device 110 scales the image of the object according to the first horizontal ratio. For example, in this example, Yb is approximately equal to Ya but Xb is significantly smaller than Xa. Therefore, the first electronic device 110 determines that Yb / Ya is greater than Xb / Xa, and scales the object image 500 according to Xb / Xa. In this example, the first electronic device 110 divides the second horizontal resolution Xb and the second vertical resolution Yb of the object image 500 by Xb / Xa to obtain a scaled object image 600, as shown in FIG. 6. Therefore, the horizontal resolution of the scaled object image 600 is Xa, and the vertical resolution is Yb * Xa / Xb.
值得注意的是，當第一縱向比值等於第一橫向比值時，第一電子裝置110可不進行縮放物體影像的操作。 It is worth noting that when the first vertical ratio is equal to the first horizontal ratio, the first electronic device 110 may not perform the operation of zooming the image of the object.
在步驟S209中，藉由第一電子裝置110將縮放後的物體影像的第二中心點定位於第一影像的第一中心點上。舉例來說，在圖7中，第一電子裝置110會將縮放後的物體影像600的中心 點定位於第一影像300的中心點上以結合縮放後的物體影像600及第一影像300。 In step S209, the second electronic point of the scaled object image is positioned on the first electronic point of the first image by the first electronic device 110. For example, in FIG. 7, the first electronic device 110 will center the center of the zoomed object image 600. The point is positioned on the center point of the first image 300 to combine the scaled object image 600 and the first image 300.
在步驟S211中，藉由第一電子裝置110接收拖曳操作來拖曳物體影像以產生物體位移量，並藉由第一電子裝置根據第一中心點與物體位移量將縮放後的物體影像結合第一影像顯示在第一電子裝置110。舉例來說，當使用者將縮放後的物體影像600從圖7的位置經過(Mxb,Myb)的位移量而位移到圖8的位置時，使用者滿意此結合結果，就可控制第一電子裝置110儲存此影像結合結果。上述範例是以縮放後的物體影像600的左上角的位移量作為說明，應理解的是，縮放後的物體影像600的左上角的位移量相當於其中心點的位移量。 In step S211, the first electronic device 110 receives a drag operation to drag the object image to generate an object displacement amount, and the first electronic device combines the scaled object image with the first according to the first center point and the object displacement amount. The image is displayed on the first electronic device 110. For example, when the user moves the zoomed object image 600 from the position in FIG. 7 to the position in FIG. 8 through the (Mxb, Myb) displacement amount, the user is satisfied with the combined result and can control the first electron The device 110 stores the image combining result. The above example uses the displacement of the upper left corner of the scaled object image 600 as an illustration. It should be understood that the displacement of the upper left corner of the scaled object image 600 is equivalent to the displacement of its center point.
值得注意的是，當使用者完成縮放後的物體影像600的位移之後，除了可以儲存此影像作為照片，還可以對此影像進行錄影操作。 It is worth noting that after the user completes the displacement of the zoomed object image 600, in addition to storing the image as a photo, the image can also be recorded.
圖9為根據本發明另一實施例的影像結合方法的流程圖。 FIG. 9 is a flowchart of an image combining method according to another embodiment of the present invention.
請參照圖9，在步驟S901中，藉由第二電子裝置120拍攝第二影像並從第二影像中擷取物體影像，並從第一電子裝置110接收第一影像，其中第二電子裝置120具有第二橫向解析度及第二縱向解析度且第一電子裝置110具有第一橫向解析度及第一縱向解析度。舉例來說，圖4的第二影像400可由第二電子裝置120拍攝，第二影像400具有第二電子裝置120的第二橫向解析度Xb及第二縱向解析度Yb。在第二電子裝置120拍攝第二影像400之 後，第二電子裝置120可利用任何去除背景的演算法將第二影像400的背景去除，以產生一個物體影像500，如圖5所示，在此物體影像500的解析度與第二影像400相同。圖3的第一影像300可由第一電子裝置110拍攝，第一影像300具有第一電子裝置110的第一橫向解析度Xa及第一縱向解析度Ya。第二電子裝置120可從第一電子裝置110接收第一影像300。 Referring to FIG. 9, in step S901, a second electronic device 120 captures a second image and captures an object image from the second image, and receives a first image from the first electronic device 110. The second electronic device 120 The first electronic device 110 has a second horizontal resolution and a second vertical resolution. For example, the second image 400 of FIG. 4 can be captured by the second electronic device 120. The second image 400 has a second horizontal resolution Xb and a second vertical resolution Yb of the second electronic device 120. Photographing the second image 400 on the second electronic device 120 After that, the second electronic device 120 may remove the background of the second image 400 using any background removal algorithm to generate an object image 500. As shown in FIG. 5, the resolution of the object image 500 and the second image 400 are as follows. the same. The first image 300 of FIG. 3 can be captured by the first electronic device 110. The first image 300 has a first horizontal resolution Xa and a first vertical resolution Ya of the first electronic device 110. The second electronic device 120 may receive the first image 300 from the first electronic device 110.
在步驟S903中，判斷第一縱向解析度與第二縱向解析度的第二縱向比值是否大於第一橫向解析度與第二橫向解析度的第二橫向比值。舉例來說，第二電子裝置120可判斷第二縱向比值Xa/Xb是否大於第二橫向比值Ya/Yb。 In step S903, it is determined whether a second longitudinal ratio of the first longitudinal resolution and the second longitudinal resolution is greater than a second lateral ratio of the first lateral resolution and the second lateral resolution. For example, the second electronic device 120 may determine whether the second vertical ratio Xa / Xb is greater than the second horizontal ratio Ya / Yb.
若第一縱向解析度與第二縱向解析度的第二縱向比值大於第一橫向解析度與第二橫向解析度的第二橫向比值，在步驟S905中，第二電子裝置120根據第二縱向比值縮放第一影像並將縮放後的第一影像結合物體影像顯示在第二電子裝置120。 If the second vertical ratio of the first vertical resolution and the second vertical resolution is greater than the second horizontal ratio of the first horizontal resolution and the second horizontal resolution, in step S905, the second electronic device 120 according to the second vertical ratio The first electronic image is scaled and displayed in combination with the object image on the second electronic device 120.
若第一縱向解析度與第二縱向解析度的第二縱向比值小於第一橫向解析度與第二橫向解析度的第二橫向比值，在步驟S907中，第二電子裝置120根據第二橫向比值縮放第一影像並將縮放後的第一影像結合物體影像顯示在第二電子裝置120。舉例來說，由於在本範例中，Xa明顯大於Xb，但Ya約等於Yb，因此第二電子裝置120會判斷Xa/Xb大於Ya/Yb，並根據Xa/Xb來縮放第一影像300。在本範例中，第二電子裝置120會將第一影像300的第一橫向解析度Xa及第二縱向解析度Ya分別除以Xa/Xb以獲 得縮放後的第一影像1000，如圖10所示。因此縮放後的第一影像1000的橫向解析度為Xb，且縱向解析度為Ya*Xb/Xa。 If the second vertical ratio of the first vertical resolution and the second vertical resolution is smaller than the second horizontal ratio of the first horizontal resolution and the second horizontal resolution, in step S907, the second electronic device 120 according to the second horizontal ratio The first electronic image is scaled and displayed in combination with the object image on the second electronic device 120. For example, in this example, Xa is significantly larger than Xb, but Ya is approximately equal to Yb. Therefore, the second electronic device 120 determines that Xa / Xb is larger than Ya / Yb, and scales the first image 300 according to Xa / Xb. In this example, the second electronic device 120 divides the first horizontal resolution Xa and the second vertical resolution Ya of the first image 300 by Xa / Xb to obtain A zoomed first image 1000 is obtained, as shown in FIG. 10. Therefore, the horizontal resolution of the scaled first image 1000 is Xb, and the vertical resolution is Ya * Xb / Xa.
在步驟S909中，藉由第二電子裝置120將縮放後的第一影像的第一中心點定位於物體影像的第二中心點上。舉例來說，第二電子裝置120會將縮放後的第一影像1000與物體影像500以各自的中心點結合並顯示於第二電子裝置120上，如圖11所示。 In step S909, the second electronic device 120 is used to locate the first center point of the scaled first image on the second center point of the object image. For example, the second electronic device 120 combines and displays the scaled first image 1000 and the object image 500 at their respective center points and displays them on the second electronic device 120, as shown in FIG. 11.
在步驟S911中，藉由第二電子裝置120接收拖曳操作來拖曳第一影像以產生背景位移量，並藉由第二電子裝置根據第二中心點與背景位移量將第一影像顯示在第二電子裝置120。舉例來說，第二電子裝置120還可提供使用者對縮放後的第一影像1000進行拖曳操作，以獲得使用者想要的結合影像，如圖12所示。 In step S911, the second electronic device 120 receives the drag operation to drag the first image to generate a background displacement amount, and the second electronic device displays the first image on the second according to the second center point and the background displacement amount. Electronic device 120. For example, the second electronic device 120 may further provide a user to perform a drag operation on the zoomed first image 1000 to obtain a combined image desired by the user, as shown in FIG. 12.
值得注意的是，在第二電子裝置120的顯示範圍中，也就是物體影像500對應的區域中，縮放後的第一影像1000以外的區域可留黑處理，而當使用者儲存影像時，第二電子裝置120可僅儲存縮放後的第一影像1000顯示於第二電子裝置120的部分以及物體影像500中的物體與縮放後的第一影像1000重疊的部分，以獲得一個完整影像1200。 It is worth noting that in the display range of the second electronic device 120, that is, the area corresponding to the object image 500, the area other than the scaled first image 1000 can be left black. When the user saves the image, the first The two electronic devices 120 may store only the portion of the scaled first image 1000 displayed on the second electronic device 120 and the portion of the object image 500 where the object overlaps with the scaled first image 1000 to obtain a complete image 1200.
綜上所述，本發明的影像結合方法與影像結合系統會在第一電子裝置拍攝第一影像(例如，主場景)並在第二電子裝置拍攝第二影像並從第二影像中擷取出物體影像(例如，人物影像)。當第一電子裝置從第二電子裝置接收物體影像時，會根據上述兩個電子裝置解析度的橫向比值及縱向比值較小者來縮放物體影像，並 將縮放後的物體影像結合第一影像顯示在第一電子裝置。當第二電子裝置從第一電子裝置接收第一影像時，會根據上述兩個電子裝置解析度的橫向比值及縱向比值較大者來縮放第一影像，並將縮放後的第一影像結合物體影像顯示在第二電子裝置。如此一來，不同解析度的影像就能以適當的比例彼此結合。此外，使用者還可利用第一電子裝置來拖曳接收到的物體影像，或是利用第二電子裝置來拖曳接收到的第一影像，以達到更佳的影像結合效果。 In summary, the image combining method and image combining system of the present invention will capture a first image (eg, a main scene) on a first electronic device, and capture a second image on a second electronic device and extract an object from the second image. Images (for example, people). When the first electronic device receives the object image from the second electronic device, the object image is scaled according to the smaller horizontal ratio and vertical ratio of the resolution of the two electronic devices, and The scaled object image is displayed on the first electronic device in combination with the first image. When the second electronic device receives the first image from the first electronic device, the first electronic image is scaled according to the larger horizontal ratio and vertical ratio of the resolution of the two electronic devices, and the scaled first image is combined with the object The image is displayed on the second electronic device. In this way, images of different resolutions can be combined with each other at an appropriate ratio.
