Description

一种拍摄方法及电子设备
本申请要求在2019年11月15日提交中国国家知识产权局、申请号为201911120504.6的中国专利申请的优先权，发明名称为“一种拍摄方法及电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电子技术领域，尤其涉及一种拍摄方法及电子设备。
背景技术
目前，手机通常都配置有多个摄像头用于满足用户各种拍摄场景。该多个摄像头可以包括多个焦段的摄像头，例如可以包括短焦(广角)摄像头、中焦摄像头和长焦摄像头。其中不同的摄像头对应不同的取景范围和变焦倍率。
用户在拍摄时，手机可以通过切换不同焦段的摄像头(即光学变焦)进行拍摄，有时也会结合数码变焦的软件处理方式对拍摄后的图片进行处理，以满足各种高倍率的拍摄场景。
然而，在高倍率的拍摄场景中，手机的取景范围仅为被摄场景的一个局部，通常较小。当拍摄对象处于运动状态时，极有可能运动到取景范围外，使得手机丢失拍摄对象，用户也只能盲目的移动手机寻找拍摄对象，拍摄体验差。
发明内容
本申请提供的一种拍摄方法，可以提升用户在高倍变焦倍率拍摄场景下的拍摄体验。
为了实现上述目的，本申请实施例提供了以下技术方案：
第一方面、提供一种拍摄预览的方法，该方法应用于包含相机的电子设备，该方法包括：启动相机，电子设备显示第一取景框，第一取景框用于显示第一预览画面，第一预览画面对应的相机的变焦倍率为第一倍率；接收用户输入的增大相机变焦倍率的第一操作；响应于第一操作，第一取景框显示第二预览画面，第二预览画面对应的相机的变焦倍率为第二倍率，第二倍率大于第一倍率；若第二倍率大于或等于预设倍率，则电子设备还显示有第二取景框，第二取景框用于显示第三预览画面，第三预览画面对应的相机的取景范围大于第二预览画面对应的相机的取景范围；其中第二取景框中还包括标记框，标记框用于标识第三预览画面中与第二预览画面取景范围相同的画面。
由此可见，用户可以使用第二取景框中取景范围更广的预览画面，对第一取景框的画面进行取景构图，以及对运动的对象进行拍摄，提升用户在高倍率拍摄场景下的拍摄体验。
一种可能的实现方式中，增大相机变焦倍率的第一操作为针对变焦倍率指示控件的一次或多次操作，双指分别向电子设备边框滑动，拖动变焦标尺，选择切换到长焦摄像头的选项，选择切换到长焦拍摄场景的选项中任一项。

一种可能的实现方式中，该方法还包括：电子设备接收用户输入的减小相机变焦倍率的第三操作；响应于第三操作，第一取景框显示第六预览画面，第六预览画面对应的相机的变焦倍率为第四倍率，第四倍率小于第二倍率；若第四倍率大于或等于预设倍率，则第二取景框显示第七预览画面，第七预览画面对应的相机的取景范围与第三预览画面对应的相机的取景范围相同，第二取景框中的标记框尺寸变大；若第四倍率小于预设倍率，则电子设备不显示第二取景框。
可见，随着用户减小相机的变焦倍率，第一取景框的取景范围变大。但第二取景框的取景范围不变，相应的，第二取景框中标记的第一取景框取景范围的标记框减大。若相机的变焦倍率减小到小于预设倍率时，则电子设备不再显示第二取景框。
一种可能的实现方式中，该方法还包括：电子设备接收用户输入的增大相机变焦倍率的第四操作；响应于第四操作，第一取景框显示第八预览画面，第八预览画面对应的相机的变焦倍率为第五倍率，第五倍率大于第二倍率；以及第二取景框显示第九预览画面，第九预览画面对应的相机的取景范围大于第八预览画面对应的相机的取景范围，且小于第三预览画面对应的相机的取景范围。

其中，变焦倍率可理解为当前摄像头的焦距相当于基准焦距的缩/放倍数。其中，基准焦距通常为手机主摄像头的焦距。
举例说明，以手机集成有短焦(广角)摄像头、中焦摄像头和长焦摄像头三个摄像头为例进行说明。其中，在手机和被拍摄物体的相对位置不变的情况下，短焦(广角)摄像头的 焦距最小，视场角最大，拍摄的图像中的物体尺寸最小。中焦摄像头的焦距大于短焦(广角)摄像头，视场角比短焦(广角)摄像头小，拍摄的图像中物体尺寸比短焦(广角)摄像头大。长焦摄像头的焦距最大，视场角最小，拍摄的图像中物体的尺寸最大。
其中，视场角用于指示手机在拍摄图像的过程中，摄像头所能拍摄到的最大的角度范围。也就是说，若待拍摄对象处于这个角度范围内，该待拍摄对象便会被手机采集到。若待拍摄对象处于这个角度范围之外，该被拍摄设备便不会被手机采集到。通常，摄像头的视场角越大，则使用该摄像头的拍摄范围就越大。而摄像头的视场角越小，则使用该摄像头的拍摄范围就越小。可以理解的是，“视场角”也可以替换为“视场范围”、“视野范围”、“视野区域”、“成像范围”或“成像视野”等词汇。
通常，用户使用中焦摄像头的场景最多，因此，一般将中焦摄像头设置为主摄像头。主摄像头的焦距设置为基准焦距，变焦倍率为“1×”。在一些实施例中，可以对主摄像头捕获的图像进行数码变焦(digital zoom)(或称为数字变焦)，即，通过手机中的ISP或其他处理器将主摄像头捕获的“1×”的图像的每个像素面积放大，并相应缩小图像的取景范围，使得处理后的图像呈现等效于主摄像头采用其他变焦倍率(例如“2×”)拍摄的图像。也就是说，使用主摄像头拍摄的图像可以对应一个区间的变焦倍率，例如：“1×”至“5×”。
类似的，长焦摄像头的焦距与主摄像头的焦距的倍数，可作为长焦摄像头的变焦倍率。例如，长焦摄像头的焦距可以为主摄像头的焦距的5倍，即长焦摄像头的变焦倍率为“5×”。同理，也可以对长焦摄像头捕获的图像进行数码变焦。即，使用长焦摄像头拍摄的图像可以对应另一个区间的变焦倍率，例如：“5×”至“50×”。
类似的，短焦(广角)摄像头的焦距与主摄像头的焦距的倍数，可作为短焦(广角)摄像头的变焦倍率。例如，短焦摄像头的焦距可以为主摄像头的焦距的0.5倍，即长焦摄像头的变焦倍率为“0.5×”。同理，也可以对短焦(广角)摄像头捕获的图像进行数码变焦。即，使用长焦摄像头拍摄的图像可以对应另一个区间的变焦倍率，例如：“0.5×”至“1×”。
当然，手机可以使用其中任一个摄像头作为主摄像头，并以主摄像头的焦距为基准焦距，本申请不做具体限定。
在一些实施例中，用户可以手动调整手机拍摄时使用的变焦倍率。
例如：如图3中(2)所示，用户可以通过在拍摄界面中操作变焦倍率指示303，调整手机使用的变焦倍率。比如：当前手机使用的变焦倍率为“1×”时，用户可以通过点击一次或多次变焦倍率指示303，使得手机使用的变焦倍率变更为“5×”，即手机显示如图4中(1)所示的拍摄界面。在图4中(1)所示的拍摄界面中，第一取景框401中预览到的图像的取景范围显然比图3中(2)中第一取景框302中的取景范围小，但第一取景框401中预览到的被拍摄对象(例如：鸟)的尺寸大于第一取景框302中预览到的被拍摄对象。在一些示例中，图4中所述的拍摄界面中还可以继续显示变焦倍率指示402，此时显示当前变焦倍率为“5×”，以便用户知晓当前的变焦倍率。
又例如：如图3中(3)所示，用户可以通过在拍摄界面中双指(或三指)捏合的手势，减小手机使用的变焦倍率，或者双指(或三指)向外滑动的手势(与捏合相反的方向)增大手机使用的变焦倍率。
又例如：如图3中(4)所示，用户也可以在拍摄界面中通过拖动变焦标尺304来改变手机使用的变焦倍率。
又例如：用户也可以在拍摄界面中或拍摄设置界面中，通过切换当前所使用的摄像头来改变手机的变焦倍率。例如，用户选择切换到长焦摄像头，则手机自动增大变焦倍率。
又例如：用户也可以在拍摄界面中或拍摄设置界面中，通过选择长焦拍摄场景的选项或者远距离的拍摄场景的选项等，来改变手机的变焦倍率。
在另一些实施例中，手机也可以自动识别摄像头捕获的图像的具体场景，根据识别的具体场景自动调整变焦倍率。比如：若手机识别出摄像头捕获的图像为视野范围较大的景物，例如大海、高山、树林等，可以自动减小变焦倍数。又比如：若手机识别出摄像头捕获的图像为远距离的物体时，例如远处的飞鸟、运动场上的运动员等，可以自动增大变焦倍数，本申请对此不做限定。
在本申请中，当手机使用的变焦倍率较高时，例如变焦倍率大于或等于第一预设倍率(例如：“10×”)时，手机的拍摄界面中除了显示第一取景框的预览图像(或者预览画面)外，还可以显示第二取景框的预览图像(或者预览画面)。第二取景框的预览图像可以辅助用户确定第一取景框取景范围。为了便于区分，将第一取景框中显示的预览图像(或者预览画面)称为主预览图(或主预览画面)，第二取景框中显示的预览图像(或者预览画面)称为辅助预览图(辅助预览画面)。
显然，第二取景框中的图像(主预览图)的视场角大于第二取景框中的图像(辅助预览图)，且第二取景框中的图像包括第一取景框中的图像。由于第一取景框的变焦倍数较大，取景范围小，不便于用户进行取景构图。或者，当待拍摄对象处于运动状态时，待拍摄对象极有可能运动到第一取景框的取景范围外，不便于用户对待拍摄对象进行跟踪拍摄。因此，用户可以借助较大取景范围的第二取景框进行取景构图，以及便于对运动中的待拍摄对象进行跟踪拍摄。
其中，第一取景框和第二取景框在手机屏幕上可以部分内容重叠，也可以不重叠，本申请对第一取景框和第二取景框的相对位置关系不做限定。
例如，如图4中(1)所示，手机拍摄界面显示当前的变焦倍率为“5×”，此时拍摄界面中仅显示有第一取景框401。当检测到用户增大变焦倍数的指示(例如变焦倍率增大到“10×”)，手机显示如图4中(2)所示的拍摄界面。在图4中(2)所示的拍摄界面中，除了显示有第一取景框403，还显示有第二取景框405。可见，第一取景框403中显示的主预览图为第二取景框405显示的辅助预览图中的一部分。例如，主预览图为辅助预览图的中心区域(或大致中心区域)的图像。在第二取景框405的图像可以包括第一标记框406，以提示用户第一取景框403中图像在第二取景框405的图像中的位置，便于用户使用第二取景框405对第一取景框403的图像进行取景构图，以及对运动的对象进行拍摄。
在一个示例中，如图4中(2)所示，第一取景框403和第二取景框405可以部分重叠。示例性的，第一取景框403可以占据手机屏幕的大部分或全部的显示区域。第二取景框405可以覆盖在第一取景框403上，位于第一取景框403的边缘位置，例如左下角、右下角、左上方、右上方等。这样，第二取景框不会遮住第一取景框中心区域，避免遮挡用户关注的区域。当然，用户可以通过例如拖动等的操作，自由地移动第二取景框的显示位置，以便有时用户需要查看第一取景框中边缘位置的图像内容，或者满足不同用户的使用习惯，或用户不同时间的使用习惯等。
可选的，第二取景框405覆盖在第一取景框403上，且位于第一取景框403的边缘位置时，第二取景框405也可以呈半透明方式进行显示。那么，第二取景框405既可以呈现更广的取景范围的辅助预览图，又不遮挡第一取景框403在该区域的图像。
可选的，第二取景框405上还可以包括关闭控件407。用户可以通过操作关闭控件407，关闭第二取景框405，即手机在拍摄界面中不再显示第二取景框405。在一些示例中，在用户 手动关闭第二取景框405之后，手机可以在原显示第二取景框405的位置或者其他位置显示一恢复控件。用户也可以通过操作该恢复控件，恢复显示第二取景框405。例如，该恢复控件可以半透明的形式悬浮在第一取景框403上，本申请对恢复控件的具体形式不做限定。
可选的，第二取景框405上还可以包括缩放控件408。当检测到用户操作缩放控件408时，手机可以将第二取景框405放大，或者手机此时只显示第二取景框405，这样，便于用户更清楚的查看到第二取景框405中的辅助预览图，可以根据辅助预览图进行取景构图等。在第二取景框405处于放大状态时，当再次检测到用户操作缩放控件408时，则手机缩小第二取景框405，这样，用户可以查看到第一取景框403的主预览图。可见，本申请可以根据用户使用场景，灵活多变显示主预览图和辅助预览图。
当然，在上述示例中，第一取景框403和第二取景框405的显示位置也可以交换。即，第二取景框405占据手机屏幕的大部分或全部的显示区域，而第一取景框403覆盖在第二取景框405上，位于第二取景框405的边缘位置。此外，手机可以根据用户的选择灵活布置第一取景框403和第二取景框405的位置。例如，用户可以通过拖动第二取景框405到第一取景框403所在的位置的操作，指示手机交换第二取景框405和第一取景框403的位置。又例如，当检测到用户在第二取景框405的边界处长按的操作，或者检测到用户手指移动到第二取景框405的边界处，手机可以显示交换控件(图中未示出)。检测到用户操作该交换控件，手机交换第二取景框405和第一取景框403的位置等。
在另一个示例中，如图4中(3)所示，第一取景框403和第二取景框405可以不重叠。示例性的，手机的显示区域可以分为不重叠两个区域(例如上下两个区域，左右两个区域等)，两个区域的面积可以相同或不同，两个区域分别用于显示第一取景框403和第二取景框405。可选的，第一取景框403和第二取景框405的显示位置可以根据用户的操作进行交换。
当然，手机也可以在不同的手机状态下自动选择不同的区域划分方法。其中，手机状态包括横屏状态或竖屏状态。例如，当手机处于横屏状态，手机的显示区域划分为左右两个区域，分别用于显示第一取景框403和第二取景框405。当手机处于竖屏状态，手机的显示区域划分为上下两个区域，分别用于显示第一取景框403和第二取景框405。在另一示例中，手机为折叠屏时，手机状态还包括折叠状态或展开状态。当手机处于折叠状态，手机的显示区域划分为上下两个区域，分别用于显示第一取景框403和第二取景框405。当手机处于展开状态，手机的显示区域划分为左右两个区域，分别用于显示第一取景框403和第二取景框405。本申请对此不做具体限定。
下面对在手机的拍摄界面中同时显示第一取景框和第二取景框的具体实现方案进行说明。
在一种技术方案中，第一取景框和第二取景框可以是同一个摄像头采集到的图像，例如长焦摄像头采集的图像。
示例性的，第一取景框中显示的图像，是根据长焦摄像头采集的原始图像，以及根据手机当前使用的变焦倍率进行处理后的图像。例如，手机当前使用的变焦倍率为“10×”，则手机先根据长焦摄像头采集的原始图像(例如：原始图像的变焦倍率为“5×”)，采用数字变焦的软件处理方式，对长焦摄像头采集到的原始图像进行裁切，以得到变焦倍率为“10×”的图像。也就是说，第一取景框中显示的图像为变焦倍率为“10×”的图像，且取景范围(或视场角)小于长焦摄像头采集的原始图像的取景范围(或视场角)。
第二取景框中显示的图像，是根据长焦摄像头采集的原始图像进行处理后的图像。在一个示例中，第二取景框中的图像，是长焦摄像头采集的原始图像的全尺寸图像，即手机没有 对长焦摄像头采集的原始图像进行裁切处理。也即，不对长焦摄像头采集到的原始图像做变焦倍率的变换。例如，长焦摄像头采集的原始图像的变焦倍率为“5×”，则第二取景框中显示的图像的变焦倍率为“5×”。
可选的，由于第二取景框中的图像仅用于辅助用户确定第一取景框的取景范围，故第二取景框的分辨率可以适当降低。因此，可以对长焦摄像头采集的原始图像进行下采样得到低分辨率的图像，显示在第二取景框中。
在第二取景框的图像中还可以包括第一标记框，用于在第二取景框中标记出第一取景框中的图像，以提示用户第一取景框中图像在第二取景框的图像中的位置。这样，当用户对第一取景框中图像进行取景构图时，可以根据视场角更大的第二取景框中显示的更多的景物进行构图设计。或者，当用户待拍摄对象运动到第一取景框的取景范围之外时，用户可以根据第二取景框中该待拍摄对象的位置，移动手机，以使得待拍摄对象能够回到第一取景框的取景范围中，便于用户对待拍摄对象进行跟踪拍摄。后续，将对这些具体场景进行详细说明，这里先不做说明。
可选的，第一标记框的标记方式可以与第二取景框的标记方式不同，例如取景框的颜色不同等，以便用户更加清晰的区分第一标记框标记的内容。
在该技术方案中，假设第二取景框的图像对应的变焦倍率为K1，第一取景框的图像对应的变焦倍率为K2，则第一标记框中图像的面积/第二取景框中图像面积＝(K1/K2) 2。例如：第二取景框对应的变焦倍率为“5×”，当前手机使用的变焦倍率为“10×”，则第一标记框中图像的面积为第二取景框中图像的面积的四分之一。比如，第二取景框的图像的尺寸为320像素×240像素，则第一标记框中的图像的尺寸为160像素×120像素。又例如：第二取景框对应的变焦倍率为“5×”，当前手机使用的变焦倍率为“50×”，则第一标记框中图像的面积为第二取景框中图像的面积的百分之一。比如，第二取景框的图像的尺寸为320像素×240像素，则第一标记框中的图像的尺寸为32像素×24像素。
并且，第一标记框的图像的中心位置，与第二取景框的图像的中心位置重合，或大体上重合。
可选的，当手机处于高倍率的拍摄场景时，手机也可以采用电子防抖(electronic image stabilitization，EIS)技术对第一取景框中的图像进行处理。那么，在第二取景框中的图像中确定第一标记框位置时，还需要补偿当前因手部抖动产生的偏移，以保证第一标记框中的图像与第一取景框中的图像的视角一致。
上述对图像进行数字变焦，以及电子防抖的具体方法可以采用本领域技术人员能够想到的任何一种方法进行处理，本申请对此不做具体限定。
可见，在该示例中，第二取景框中的辅助预览图像的变焦倍率不变，第二取景框中的第一标记框的面积会随着手机当前使用的变焦倍率变化而改变。具体的，第一标记框的面积与手机当前使用的变焦倍率(即主预览图的变焦倍率)成反比。在这种情况下，随着手机当前使用的变焦倍率的增大，第一标记框的面积变小。
在另一个示例中，当手机的变焦倍率切换到大于第二预设倍率(例如：“20×”)，第二预设倍率大于或等于第一预设倍率，则此时第二取景框中的图像，可以是长焦摄像头采集的原始图像进行裁切后的图像。即，第二取景框中的图像，可以对长焦摄像头采集到的原始图像做数字变焦处理，得到较大变焦倍率的图像。但，第二取景框中的图像的变焦倍率通常小于手机当前所使用的变焦倍率。这样，第二取景框中的图像，相较于长焦摄像头采集到的原始图像，与第一取景框中的图像的变焦倍率更加接近，取景范围也更加接近，有利于用户根据 第二取景框中图像更加精准的确定第一取景框中待拍摄对象。例如，手机的变焦倍率切换到“20×”时，手机的ISP或处理器对长焦摄像头采集到的原始图像(变焦倍率为“5×”)进行数字变换，得到较大的变焦倍率(例如“10×”)的图像，显示在第二取景框中。
可选的，第二取景框中的图像也可以是低分辨率的图像(相对于长焦摄像头采集的原始图像)。处理方法可参考上一个示例中的相关内容的描述，这里不赘述。
在第二取景框的图像中还可以包括第一标记框，用于在第二取景框中标记出第一取景框中的图像，其余内容可参考上一个示例中的相关内容的描述，这里也不赘述。
可见，在该示例中，第二取景框中的辅助预览图像的变焦倍率可以随着手机当前使用的变焦倍率变化而改变。在这种情况下，随着手机当前使用的变焦倍率的增大，第二取景框中的第一标记框的面积可能不变。
在另一种技术方案中，也可以是手机同一侧的不同摄像头(例如：不同的后置摄像头)采集到的图像，例如第一取景框是长焦摄像头采集的图像，第二取景框是主摄像或广角摄像头采集的图像。
第一取景框中显示的图像，是根据长焦摄像头采集的原始图像，以及根据手机当前使用的变焦倍率进行处理后的图像。第一取景框显示的图像的处理与第一种技术方案相同，这里不再赘述。
第二取景框中显示的图像，是根据主摄像头或广角摄像头采集的原始图像进行处理后的图像。这里以主摄像头为例进行说明。
在一个示例中，第二取景框中的图像，是主摄像头采集的原始图像的全尺寸图像，即手机没有对主摄像头采集的原始图像进行裁切处理。也即，不对主摄像头采集到的原始图像做变焦倍率的变换。例如，主摄像头采集的原始图像的变焦倍率为“1×”，则第二取景框中显示的图像的变焦倍率为“1×”。
可选的，由于第二取景框中的图像仅用于辅助用户确定第一取景框的取景范围，故第二取景框的分辨率可以适当降低。因此，可以对主摄像头采集的原始图像进行下采样得到低分辨率的图像，显示在第二取景框中。
在第二取景框的图像中还可以包括第一标记框，用于在第二取景框中标记出第一取景框中的图像，以提示用户第一取景框中图像在第二取景框的图像中的位置。
在该技术方案中，假设第二取景框的图像对应的变焦倍率为K1，第一取景框的图像对应的变焦倍率为K2，则第一标记框中图像的面积/第二取景框中图像面积＝(K1/K2) 2。例如：第二取景框对应的变焦倍率为“1×”，当前手机使用的变焦倍率为“10×”，则第一标记框中图像的面积为第二取景框中图像的面积的百分之一。比如，第二取景框的图像的尺寸为320像素×240像素，则第一标记框中的图像的尺寸为32像素×24像素。
并且，第一标记框的图像的中心位置，与第二取景框的图像的中心位置大体上重合。由于第一取景框的图像是由长焦摄像头采集的图像得到，第二取景框的图像是由主摄像头采集的图像得到，而长焦摄像头和主摄像头在手机上的位置不同。因此，可以根据长焦摄像头和主摄像头的相对距离，对第一标记框的图像的中心位置进行调整，使得第一标记框中的图像与第一取景框中的图像的视野一致。当然，当手机采用EIS技术对第一取景框中的图像进行处理的情况下，在第二取景框中的图像中确定第一标记框位置时，还需要补偿当前因手部抖动产生的偏移。
可见，在该示例中，第二取景框中的辅助预览图像的变焦倍率不变，第二取景框中的第一标记框的面积会随着手机当前使用的变焦倍率变化而改变。具体的，第一标记框的面积与 手机当前使用的变焦倍率成反比。在这种情况下，随着手机当前使用的变焦倍率的增大，第一标记框的面积变小。
在另一个示例中，当手机的变焦倍率切换到大于第二预设倍率(例如：“20×”)，第二预设倍率大于或等于第一预设倍率，则此时第二取景框中的图像，可以是主摄像头采集的原始图像进行裁切后的图像。即，第二取景框中的图像，可以对主摄像头采集到的原始图像做数字变焦处理，得到较大变焦倍率的图像。但，第二取景框中的图像的变焦倍率通常小于手机当前所使用的变焦倍率。这样，第二取景框中的图像，相较于主摄像头采集到的原始图像，与第一取景框中的图像的变焦倍率更加接近，取景范围也更加接近，有利于用户根据第二取景框中图像更加精准的确定第一取景框中待拍摄对象。例如，手机的变焦倍率切换到“20×”时，手机的ISP或处理器对主摄像头采集到的原始图像(变焦倍率为“1×”)进行数字变换，得到较大的变焦倍率(例如“5×”)的图像，显示在第二取景框中。其他内容参考上一个示例中的相关内容的描述，不再赘述。
可见，在该示例中，第二取景框中的辅助预览图像的变焦倍率可以随着手机当前使用的变焦倍率变化而改变。在这种情况下，随着手机当前使用的变焦倍率的增大，第二取景框中的第一标记框的面积可能不变。
在本申请的一些实施例中，手机会以一定的频率刷新第一取景框和第二取景框中显示的图像。手机也会一直监控主预览图的变焦倍率。当检测到主预览图的变焦倍率在大于第一预设倍率的范围内变动时，手机自动调整辅助预览图中第一标记框的大小，并保持刷新第一取景框和第二取景框中的预览图像。当检测到变焦倍率小于第一预设倍率时，手机可自动关闭第二取景框405显示的辅助预览图，并保持刷新第一取景框的预览图像。
在本申请的又一些实施例中，当手机检测到用户关闭第二取景框的辅助预览图的操作时，手机关闭辅助预览图。也就是说，在手机本次拍照过程中，即便手机的变焦倍率大于或等于第一预设倍率时，手机也将不再开启第二取景框的辅助预览图。本次拍照过程，可认为是从手机本次开启相机应用后，一直到退出相机应用或关机重启的过程(包括相机处于后台运行的情况)。在手机退出相机应用后，或者手机关机后重启，当手机再次开启相机应用时，可认为是手机的下一次拍照过程。
在本申请的又一些实施例中，当手机检测到用户关闭第二取景框的辅助预览图的次数达到预定次数时，手机也可以默认关闭手机的辅助预览图的功能。也就是说，当手机退出相机应用后，重新开启相机应用后，手机也不再显示第二取景框的辅助预览图。在一些示例中，手机可以通过恢复出厂设置，重新开启辅助预览图的功能。
在本申请的又一些实施例中，手机也可以设置辅助预览图功能的开关控件。用户可以通过该开关控件，自由的选择开启或关闭高倍率下的辅助预览图的功能。例如，可以在设置应用的一个选项中设置一个辅助预览图的开关控件。又例如，也可以在相机应用的设置里，设置一个辅助预览图的开关控件。又例如，还可以在相机的拍摄界面上，设置一个辅助预览图的开关控件。其中，本申请对辅助预览图功能的开关控件的具体形式和位置不做限定。当然，用户还可以通过语音命令、隔空手势、按压物理按键或物理按键组合等其他方式开启或关闭辅助预览图的功能。
在介绍完拍摄界面能够同时显示第一取景框的主预览图和第二取景框的辅助预览图后，下面结合具体场景，对用户使用第二取景框的辅助预览图，对第一取景框的主预览图进行取景构图，以及对运动的拍摄对象进行跟踪拍摄的过程进行详细说明。
可以理解的是，用户可以在拍摄照片以及录制视频的场景中，均可以使用第二取景框的 辅助预览图进行拍摄，这里以拍摄照片的场景为例，进行说明。
场景1、拍摄静态景物，利用辅助预览图进行取景构图
例如，如图5中(1)所示，为手机显示一个拍摄界面。该拍摄界面包括第一取景框501的主预览图，第二取景框502的辅助预览图。此时，手机的变焦倍率为“10×”，在第一取景框501中的主预览图中仅能看完整的看清楚一只飞鸟。若用户想要拍摄其他对象，则可以从第二取景框502中更广的取景范围内，寻找新的拍摄对象。比如，用户可以从第二取景框502的辅助预览图中选择远处椰子树的椰果进行拍摄。
在一个示例中，由于第二取景框502中的第一标记框503清晰的标识出第一取景框的取景范围，则用户可以根据新的拍摄对象与第一标记框503的相对位置关系，移动手机或者翻转手机。例如，新的拍摄对象椰果位于第一标记框的右上方，则用户向右上方向移动手机或者向右上方翻转手机。需要注意的是，在移动手机的过程中，手机也在实时刷新第二取景框502中的辅助预览图，故用户可以根据新的拍摄对象是否已移入到辅助预览图中第一标记框503内，来确定新的拍摄对象已移入第一取景框的取景范围内。进一步的，由于第一标记框503中的图像与第一取景框501中的图像的取景范围是相同的，故用户可以通过对辅助预览图中第一标记框503中的取景构图，实现对第一取景框501的取景构图。例如，如图5中(2)所示，为用户确定的新的拍摄对象的拍摄界面。
可选的，用户也可以通过操作缩放控件504，将第二取景框502的辅助预览图放大，以便用于更清楚的查看到辅助预览图中的细节，对主预览图进行取景构图。
可选的，在用户完成对主预览图的取景构图后，可通过操作第二取景框502中的关闭控件505，关闭第二取景框502。这样，便于用户查看到完整的主预览图，避免在拍摄的过程中，辅助预览图遮挡用户的视线。
在另一个示例中，用户也可以在辅助预览图中选择待拍摄的对象，手机可以自动计算出待拍摄对象与当前第一标记框相对方向和距离，提示用户移动或翻转手机，使得待拍摄对象移入第一标记框中，完成对待拍摄对象的取景构图。
例如，如图5中(1)所述的拍摄界面，用户可以通过操作缩放控件504，将第二取景框502的辅助预览图放大，例如显示如图5中(3)所示的拍摄界面。可选的，在图5中(3)所示的拍摄界面中，也可以显示提示信息，提示用户当前的预览图为辅助预览图。或者，在图5中(3)所示的拍摄界面中，也可以显示恢复第一取景框主预览图的控件，既可以提示用户当前的预览图为辅助预览图，也可以通过该控件快速恢复第一取景框的主预览图。可选的，在该拍摄界面中，也可以隐藏当前手机所使用的变焦倍率的指示，避免用户混淆辅助预览图对应的变焦倍率和当前手机所使用的变焦倍率。在一个示例中，当手机再次显示主预览图时，也可以自动恢复当前手机所使用的变焦倍率的指示。
用户可以在第二取景框502的辅助预览图中选择待拍摄对象。在一个示例中，用户可以点击该辅助预览图中的椰果，手机可以自动以用户点击操作的位置为中心，框选出与第一标记框503面积相同的一个第二标记框506。第二标记框506可以认为是用户选择的待拍摄对象。手机可以计算第一标记框503的中心位置与第二标记框506中心位置的相对方向和距离。然后，根据计算出的相对方向和距离，计算出手机应移动的方向和距离，或者翻转的角度，并提示用户，如图5中(4)所示的提示信息507。当然，手机也可以采用语音、图案(箭头)、动画等其他方式指导用户移动或翻转手机。在另一个示例中，手机也可以采用图像识别技术，对第二取景框502的辅助预览图中的景物进行识别。在用户选择待拍摄对象后，以识别出的物体为单位，确定为待拍摄对象。也就是说，第二标记框506的面积可以与第一标记框503 的面积不同。
此外，在该举例中，拍摄界面还可以显示其他内容，例如，显示提示用户选择待拍摄对象的信息或播放语音等。又例如：在用户移动手机的过程中，手机也可以实时计算待移动的方向和距离等，实时更新指导信息。
在确定将待拍摄对象移入第一标记框503后，用户可以通过点击关闭控件505关闭第二取景框502。此时，手机显示第一取景框501的主预览图，可选的，用户也可以通过点击缩放控件504，缩小第二取景框502的辅助预览图。此时手机显示第一取景框501的主预览图以及第二取景框502的辅助预览图，用户根据主预览图和辅助预览图决定指示手机执行拍摄操作的时机。
在手机执行拍摄操作后，手机最后生成的图像与第二取景框中的图像的视角相同。
需要注意的是，在上述第一种技术方案中，即分别对同一个摄像头(例如长焦摄像头)采集的原始图像进行处理得到第一取景框的主预览图和第二取景框的辅助预览图的方案中，手机最后拍摄得到的图像(也即第一取景框的主预览图)是裁切该摄像头采集的原始图像(或者第二取景框的辅助预览图)中心区域的图像，并进行数字变焦得到的图像。其中，裁切的图像对应手机当前手机所使用变焦倍率K1，当前摄像头采集的原始图像对应的变焦倍率为K3，裁切的图像的面积/原始图像的面积＝(K1/K3) 2。或者，第二取景框的辅助预览图对应的变焦倍率为K2，裁切的图像的面积/第二取景框的辅助预览图的面积＝(K1/K2) 2。例如，当前手机使用的变焦倍率为“10×”，长焦摄像头对应的变焦倍率为“5×”，则裁切的图像的面积为原始图像的面积的四分之一。
基于本申请的发明构思，可以想到，用户在辅助预览图中选择待拍摄的对象，手机也可以用户选择的拍摄的对象为中心进行裁切，得到最后拍摄的图像。也就是说，用户在辅助预览图中选择新的拍摄对象后，用户也可以不移动手机。例如，用户可以点击该辅助预览图中的椰果，手机可以自动以用户点击操作的位置为中心，框选出与手机当前所使用变焦倍率对应的视角范围的图像。在用户指示手机执行拍摄操作后，手机从摄像头拍摄的原始图像(或第二取景框的预览图)中裁切该范围的图像，并进行数字变焦得到最后拍摄得到的图像。
场景2、对运动物体进行跟踪拍摄
一种情况中，当用户用手机对准待拍摄对象时，待拍摄对象先位于第一取景框内，当待拍摄对象发生位移(位移速度较慢，位移距离较短)，并移动到第一取景框外。若待拍摄对象仍然处于第二取景框内，则可以根据上述场景1的方法，用户人为根据第二取景框的辅助预览图调整手机的位置，使得待拍摄对象移入到辅助预览图的第一标记框中。
另一种情况中，当待拍摄对象处于运动状态时(持续性发生位移，或者位移速度较快时)，手机可以在第二取景框的辅助预览图中，对待拍摄对象进行标记，这样用户可以方便的在辅助预览图中注意到待拍摄对象的运动轨迹。
例如，如图6中(1)所示，为第二取景框601的辅助预览示意图。此时，可以看到待拍摄对象先位于第一标记框602中，即位于第一取景框(这里未示出)的取景范围内。在辅助预览图中可以包括标记603，用于对待拍摄对象进行标记。例如，用醒目的三角形标记在待拍摄对象下方进行标记，或者用矩形框圈出待拍摄对象等，本申请对标记的方式不做限定。
在一些示例中，如图6中(2)所示，当待拍摄对象运动到第一标记框外时，用户可以根据标记603快速定位出待拍摄对象的位置，调整手机的移动方向或移动距离。或者，当手机检测到标记603移出第一标记框后，也可以自动根据标记603的位置和第一标记框的位置进行计算，计算出手机应当移动的方向或位置，或者旋转手机的角度。手机显示提示信息或提 示标识，或播放语音，指引用户移动手机或旋转手机。
其中，手机确定待拍摄对象的方法，可以是用户指定待拍摄对象，也可以是手机根据第一取景框中连续M(M为大于2的整数)幅画面中都识别到某个物体(例如：飞鸟)，自动确定该物体为待拍摄对象。
可选的，在手机确定待拍摄对象后，在第一取景框中可以对待拍摄对象进行自动对焦，拍摄出更清晰的待拍摄对象。
又一种情况中，当待拍摄对象运动的速度较快时，从第一标记框中移出，并已移除第二取景框时，用户可以通过放大第二取景框的变焦倍率，使得第二取景框的取景范围变大，以便在更大的取景范围内寻找到待拍摄对象。
例如，如图7中(1)所示，为第二取景框601的辅助预览示意图。此时，可以看到待拍摄对象先位于第一标记框602中，即位于第一取景框(这里未示出)的取景范围内。第二取景框601中还可以包括变焦倍率指示701，用于指示第二取景框601的辅助预览图的变焦倍率。此时，辅助预览图的变焦倍率为“5×”。
如图7中(2)所示，当待拍摄对象移动速度较快时，或者用户手抖，使得待拍摄对象不在第二取景框的辅助预览图中。但由于此时待拍摄对象应该在该拍摄位置的附近，故可以通过改变辅助预览图的变焦倍率查找待拍摄对象。例如，可以指示手机减小辅助预览图的变焦倍率，增大辅助预览图的取景范围。如图7中(3)所示，当辅助预览图的变焦倍率为较小值(例如“3×”)时，待拍摄对象出现在辅助预览图中。用户可进一步根据辅助预览图移动或翻转手机。
需要注意的是，这里第二取景框601中的变焦倍率指示701，与手机当前使用的变焦倍率无关。手机当前使用的变焦倍率为第一取景框中主预览图的变焦倍率。
又例如，当手机检测到待拍摄对象从第一标记框602中移出时，手机也可以自动的减小辅助预览图的变焦倍率，直到辅助预览图中出现待拍摄对象为止。
可选的，当用户移动或翻转手机，使得待拍摄对象重新出现在第一标记框602中时，手机也可以自动将辅助预览图的变焦倍率调回默认值(例如“10×”)。
可见，手机可以借助第二取景框601，实现对待拍摄对象的跟踪拍摄。
又一种情况中，用户也可以指示或者手机自动增大第二取景框的辅助预览图的变焦倍率，以查看第一标记框附近更清晰的景物，便于对第一标记框中的图像进行取景构图。相关操作类似，这里不再赘述。
上述实施例是以相机应用中的拍摄照片为例进行说明的，相机应用的录制视频也可以使用本申请的辅助预览功能，方法类似，这里简单说明下。
在手机开启录制视频的功能，未开始录制时，可以采用本申请提供的方法，在高变焦倍率(变焦倍率大于第一预设倍率)的情况下，显示主预览图和辅助预览图，便于用户根据取景范围更广的辅助预览图，对主预览图进行构图设计。
在手机录制视频的过程中，在高变焦倍率的场景下，显示主预览图和辅助预览图，便于用户在录制视频的过程中根据辅助预览图进行取景，以及对运动物体进行跟踪拍摄。
例如，在录制视频的过程中，若用户想要拍摄的对象发生变化时，可以借助第二取景框中更广取景范围的辅助预览图，确定新的拍摄对象，并移动手机继续录制。或者，在第二取景框中选择新的拍摄对象，手机可以显示或播放提示，指导用户移动手机以使得新的拍摄对象出现在第一取景框(即录制的范围)中。
又例如，在录制视频的过程中，若用户拍摄的对象处于运动状态时，手机可以在第二取 景框的辅助预览图中，对拍摄对象进行标记，这样用户可以方便的在辅助预览图中注意到拍摄对象的运动轨迹。当拍摄物体移动到主预览图外时，用户可以通过辅助预览图快速找到拍摄物体，移动手机以便快速找回拍摄物体。或者，手机也可以根据标记指导用户移动手机。其他内容请参见上文相关内容的描述，这里不再赘述。
