请参阅图2，本申请实施方式还提供一种电子装置1000。电子装置1000包括摄像头模组100。摄像头模组100包括主摄像头10和长焦摄像头20。主摄像头10用于获取第一像素尺寸的主原始图像，长焦摄像头20用于获取第二像素尺寸的长焦原始图像。长焦摄像头20包括第一长焦距状态和第二长焦距状态。摄像头模组100用于输出第三像素尺寸的目标图像。第一像素尺寸和第二像素尺寸均大于第三像素尺寸。本申请实施方式的变焦方法可由本申请实施方式的电子装置1000实现。例如，摄像头模组100可用于执行01、02和03中的方法。
也即是说，在摄像头模组100处于小于第一预定变焦倍数的变焦模式时，主摄像头10可以获取主原始图像，摄像头模组100可以根据主原始图像得到目标图像；在摄像头模组100处于大于或等于第一预定变焦倍数且小于第二预定变焦倍数的变焦模式时，长焦摄像头20可以以第一长焦距状态获取长 焦原始图像，摄像头模组100可以根据长焦原始图像得到目标图像；在摄像头模组100处于大于或等于第二预定变焦倍数的变焦模式时，长焦摄像头20可以以第二长焦距状态获取长焦原始图像，摄像头模组100可以根据长焦原始图像得到目标图像。
需要指出的是，本申请实施方式可以是：第一种方式，由处理器200控制主摄像头10获取主原始图像、控制长焦摄像头20以第一长焦距状态获取长焦原始图像、控制长焦摄像头20以第二长焦距状态获取长焦原始图像，并对主原始图像和长焦原始图像进行相关的图像处理得到目标图像；或者是第二种方式，由主摄像头10直接获取主原始图像(而非由于处理器200控制)，长焦摄像头20直接以第一长焦距状态获取长焦原始图像(而非由于处理器200控制)、长焦摄像头20直接以第二长焦距状态获取长焦原始图像(而非由于处理器200控制)，然后摄像头模组100对主原始图像和长焦原始图像进行相关的图像处理得到目标图像。本申请实施方式以上述第一种方式为例进行说明，而第二种方式与第一种方式类似，不再重复展开说明。
目前的镜头一般通过数码变焦获取全焦段的图像，然而数码变焦是通过对图像进行放大处理来实现的，会使得图像的解析力下降，无法保证全焦段的图像的解析力不变。
本申请实施方式的变焦方法和电子装置1000通过设置主摄像头10和长焦摄像头20，且长焦摄像头20包括第一长焦距状态和第二长焦距状态，从而在不同变焦倍数的变焦模式下，分别根据主摄像头10获取的主原始图像、长焦摄像头20以第一长焦距状态获取的长焦原始图像、以及长焦摄像头20以第二长焦距状态获取的长焦原始图像得到目标图像，能够保证全焦段的目标图像的解析力不变，提高成像性能。
具体地，电子装置1000可以是手机、平板电脑、笔记本电脑、智能穿戴设备(如智能手表、智能手环、智能眼镜、智能头盔等)、头显设备、虚拟现实设备等等，在此不做限制。
主摄像头10用于获取第一像素尺寸的主原始图像，长焦摄像头20用于获取第二像素尺寸的长焦原始图像，摄像头模组100最终输出第三像素尺寸的目标图像。第一像素尺寸和第二像素尺寸均大于第三像素尺寸。例如可以是：第一像素尺寸大于第二像素尺寸，第二像素尺寸大于第三像素尺寸；或者，第一像素尺寸等于第二像素尺寸，第一像素尺寸(第二像素尺寸)大于第三像素尺寸；或者，第一像素尺寸小于第二像素尺寸，第一像素尺寸大于第三像素尺寸。本申请实施方式以第一像素尺寸等于第二像素尺寸、第一像素尺寸(第二像素尺寸)大于第三像素尺寸为例进行说明。在一个实施例中，第一像素尺寸可以为4800万像素，第二像素尺寸可以为4800万像素，第三像素尺寸可以为1200万像素。
主摄像头10可为普通摄像头(视场范围位于长焦摄像头的视场范围与广角摄像头的视场范围之间)，也可为广角摄像头，主摄像头10可以是定焦镜头，也可为变焦镜头。长焦摄像头20为变焦镜头，长焦摄像头20能够包括第一长焦距状态和第二长焦距状态。第一长焦距状态可以为长焦摄像头20以第一预定倍数光学变焦获取长焦原始图像的状态。第二长焦距状态可以为长焦摄像头20以第二预定倍数光学变焦获取长焦原始图像的状态。第二长焦距状态对应的焦距大于第一长焦距状态对应的焦距。当摄像头模组100用于获取较近距离的被摄物体的目标图像时，可采用主摄像头10拍摄图像；当摄像头模组100用于获取中等距离的被摄物体的目标图像时，可采用长焦摄像头20以第一长焦距状态拍摄图像；当摄像头模组100用于获取较远距离的被摄物体的目标图像时，可采用长焦摄像头20以第二长焦距状态拍摄图像。
请参阅图3，本申请实施方式的摄像头模组100能够工作于小于第一预定变焦倍数的变焦模式、大于或等于第一预定变焦倍数且小于第二预定变焦倍数的变焦模式、以及大于或等于第二预定变焦倍数的变焦模式。本申请实施方式以第一预定变焦倍数为3倍、第二预定变焦倍数为5倍为例进行说明，即摄像头模组100能够工作于小于3倍的变焦模式、大于或等于3倍且小于5倍的变焦模式、以及大于或等于5倍的变焦模式。
可以理解，在其他例子中，第一预定变焦倍数也可以不为3倍、第二预定变焦倍数也可以不为5倍。第一预定变焦倍数可以设置为2倍、4倍或5倍等其他倍率。此时，长焦摄像头20的第一长焦距状态对应的变焦倍数也对应为2倍、4倍或5倍等其他倍率。第二预定变焦倍数可以设置为3倍、4倍或6倍等其他倍率。此时，长焦摄像头20的第二长焦距状态对应的变焦倍数也对应为3倍、4倍或6倍等其他倍率。例如，当第一预定变焦倍数设置为2倍时，长焦摄像头20的第一长焦距状态对应的变焦倍数也对应为2倍，第二预定变焦倍数可以设置为3倍，长焦摄像头20的第二长焦距状态对应的变焦倍数也对应为3倍；当第一预定变焦倍数设置为4倍时，长焦摄像头20的第一长焦距状态对应的变焦倍数也对应为4倍，第二预定变焦倍数可以设置为6倍，长焦摄像头20的第二长焦距状态对应的变焦倍数也对应为6倍；当第一预定变焦倍数设置为5倍时，长焦摄像头20的第一长焦距状态对应的变焦倍数也对应为5倍，第二预定变焦倍数可以设置为6倍，长焦摄像头20的第二长焦距状态对应的变 焦倍数也对应为6倍。
以摄像头模组100的变焦模式的整个变焦倍数段是0～10倍为例。摄像头模组100能够在(0，3)变焦倍数段内进行变焦，该区间内由由主摄像头10获取主原始图像，从而得到目标图像。摄像头模组100还能够在[3，5)变焦倍数段内进行变焦，该区间内由长焦摄像头20以第一长焦距状态获取长焦原始图像，从而得到目标图像。摄像头模组100还能够在[5，10]变焦倍数段内进行变焦，该区间内由长焦摄像头20以第二长焦距状态获取长焦原始图像，从而得到目标图像。本申请实施方式的变焦方法能够保证全焦段(0,10]的目标图像的解析力不变，提高成像性能。
其中，由主原始图像或长焦原始图像得到目标图像的过程可以包括有对主原始图像或长焦原始图像进行图像处理的过程，例如第一图像处理和/或第二图像处理。通过对主原始图像或长焦原始图像进行第一图像处理和/或第二图像处理可以由4800万像素的主原始图像或4800万像素的长焦原始图像得到1200万像素的目标图像。该第一图像处理可以是压缩处理，该第二图像处理可以是裁剪处理。当然，在其他实施方式中，由主原始图像或长焦原始图像得到目标图像的过程也可以不仅仅包括第一图像处理和/或第二图像处理，还可以由更多方式的图像处理，在此不作限制。
请参阅图4，在一个实施例中，压缩处理可以包括均值运算。具体地，每帧主原始图像和每帧长焦原始图像(以下统称为原始图像)中均包括呈二维分布的多个像素，例如4*4的像素。多个像素的像素值从左至右、从上至下依次为：135、132、120、105、160、140、112、110、153、89、87、62、105、87、53、45。多个像素中的预定个像素可作为一组(例如虚线框圈出的4个像素作为一组)，通过对每组内4个像素的像素值进行压缩处理，最终得到目标图像中的一个合并像素的像素值。例如，对左上角的4个像素的像素值进行均值运算，(135+132+160+140)/4＝133，得到目标图像中的左上角的合并像素的像素值为133。依此类推，对右上角的4个像素的像素值进行均值运算，得到目标图像中的右上角的合并像素的像素值为112；对左下角的4个像素的像素值进行均值运算，得到目标图像中的左下角的合并像素的像素值为109；对右下角的4个像素的像素值进行均值运算，得到目标图像中的右下角的合并像素的像素值为62，在此不一一展开说明。最终，像素值为133的合并像素、像素值为112的合并像素、像素值为109的合并像素、像素值为62的合并像素形成一帧目标图像。
需要指出的是，在实际处理过程中，处理器200需要对原始图像中的4800万像素进行均值运算，得到1200万像素的目标图像，要处理的像素数量远超过上述示例中的4*4的像素。
本实施例中，通过压缩处理得到的目标图像的像素值均直接来源于原始图像，并且没有增添像素，因此通过对原始图像进行压缩处理得到的目标图像的解析力不会降低。
请参阅图5，在另一个实施例中，压缩处理可以包括最大值运算。仍以前述4*4像素的原始图像为例，通过对每组内4个像素的像素值进行压缩处理，最终得到目标图像中的一个合并像素的像素值。例如，对左上角的4个像素的像素值进行最大值运算，MAX(135，132，160，140)＝160，得到目标图像中的左上角的合并像素的像素值为160。依此类推，对右上角的4个像素的像素值进行最大值运算，得到目标图像中的右上角的合并像素的像素值为120；对左下角的4个像素的像素值进行最大值运算，得到目标图像中的左下角的合并像素的像素值为153；对右下角的4个像素的像素值进行最大值运算，得到目标图像中的右下角的合并像素的像素值为87，在此不一一展开说明。最终，像素值为160的合并像素、像素值为120的合并像素、像素值为153的合并像素、像素值为87的合并像素形成一帧目标图像。
需要指出的是，在实际处理过程中，处理器200需要对原始图像中的4800万像素进行最大值运算，得到1200万像素的目标图像，要处理的像素数量远超过上述示例中的4*4的像素。
本实施例中，通过压缩处理得到的目标图像的像素值均来源于原始图像(像素值均为原始图像中的原始值)，并且没有增添像素，因此通过对原始图像进行压缩处理得到的目标图像的解析力不会降低。
请参阅图6，在一个实施例中，裁剪处理可以包括从原始图像中截取长宽比和原始图像相同的像素区域，并将此像素区域作为目标图像，此像素区域之外的像素则舍弃。例如，当希望由4800万像素的原始图像得到1200万像素的目标图像时，裁剪处理截取的图像像素个数为原始图像的像素个数的四分之一，因此长和宽均为原始图像的二分之一，目标图像的视场范围为原始图像的二分之一，视觉效果上为2倍变焦的视觉效果。
本实施例中，通过裁剪处理得到的目标图像的像素值均来源于原始图像(像素值均为原始图像中的原始值)，并且没有增添像素，因此通过对原始图像进行裁剪处理得到的目标图像的解析力不会降低。
请参阅图7，在某些实施方式中，在摄像头模组100处于小于第一预定变焦倍数的变焦模式时，控制主摄像头10获取主原始图像，并根据主原始图像得到目标图像(即01)，包括：
011：在摄像头模组100处于第一变焦倍数的变焦模式时，控制主摄像头10获取主原始图像，并对主原始图像进行第一图像处理得到目标图像；
012：在摄像头模组100处于第二变焦倍数的变焦模式时，控制主摄像头10获取主原始图像，并对主原始图像进行第二图像处理得到目标图像；和
013：在摄像头模组100处于第一变焦倍数和第二变焦倍数之间的变焦模式时，控制主摄像头10获取主原始图像，并对主原始图像进行第一图像处理和第二图像处理得到目标图像；
其中，第一变焦倍数和第二变焦倍数均小于第一预定变焦倍数。
请参阅图2，在某些实施方式中，处理器200可用于执行011、012和013中的方法。
也即是说，处理器200可以用于：在摄像头模组100处于第一变焦倍数的变焦模式时，控制主摄像头10获取主原始图像，并对主原始图像进行第一图像处理得到目标图像；在摄像头模组100处于第二变焦倍数的变焦模式时，控制主摄像头10获取主原始图像，并对主原始图像进行第二图像处理得到目标图像；和在摄像头模组100处于第一变焦倍数和第二变焦倍数之间的变焦模式时，控制主摄像头10获取主原始图像，并对主原始图像进行第一图像处理和第二图像处理得到目标图像；其中，第一变焦倍数和第二变焦倍数均小于第一预定变焦倍数。
请参阅图2，在某些实施方式中，摄像头模组100可用于执行011、012和013中的方法。
也即是说，在摄像头模组100处于第一变焦倍数的变焦模式时，主摄像头10可以获取主原始图像，摄像头模组100可以对主原始图像进行第一图像处理得到目标图像；在摄像头模组100处于第二变焦倍数的变焦模式时，主摄像头10可以获取主原始图像，摄像头模组100可以对主原始图像进行第二图像处理得到目标图像；在摄像头模组100处于第一变焦倍数和第二变焦倍数之间的变焦模式时，主摄像头10可以获取主原始图像，摄像头模组100可以对主原始图像进行第一图像处理和第二图像处理得到目标图像；其中，第一变焦倍数和第二变焦倍数均小于第一预定变焦倍数。
本申请实施方式以第一变焦倍数为1倍、第二变焦倍数为2倍为例进行说明。主摄像头10的固定焦距即可为第一变焦倍数对应的焦距。
请参阅图8，在摄像头模组100处于1倍的变焦模式时，处理器200控制主摄像头10获取4800万像素的主原始图像，并对4800万像素的主原始图像进行压缩处理得到1200万像素的目标图像。具体地，压缩处理可以是前述均值运算或最大值运算。本申请实施方式通过对4800万像素的主原始图像进行压缩处理，电子装置1000可输出视场范围不变的1200万像素的目标图像。
请参阅图9，在摄像头模组100处于2倍的变焦模式时，处理器200控制主摄像头10获取4800万像素的主原始图像，并对4800万像素的主原始图像进行裁剪处理得到1200万像素的目标图像。由于2倍的变焦模式对应的视场范围一般小于1倍的变焦模式对应的视场范围，因此，本申请实施方式需要对4800万像素的主原始图像进行裁剪处理，以减小视场范围，使得电子装置1000输出相较于1倍的变焦模式下，视场范围减小、解析力不变的1200万像素的目标图像。其中，裁剪处理所截取的区域可以是主原始图像最中间的区域，也可以是根据用户输入所确定的区域。
请参阅图10，在摄像头模组100处于1倍和2倍之间的变焦模式时(例如1.5倍的变焦模式)，处理器200控制主摄像头10获取4800万像素的主原始图像，并对4800万像素的主原始图像进行裁剪处理和压缩处理得到1200万像素的目标图像。处理器200具体可以是先对4800万像素的主原始图像进行裁剪处理得到中间图像，再对中间图像进行压缩处理得到1200万像素的目标图像。中间图像的像素尺寸小于主原始图像的像素尺寸，且大于目标图像的像素尺寸。例如，中间图像的像素尺寸可以是2100万像素。处理器200先对4800万像素的主原始图像进行裁剪处理得到2100万像素的中间图像，裁剪处理所截取的区域可以是主原始图像最中间的区域，也可以是根据用户输入所确定的区域。然后，处理器200对2100万像素的中间图像进行压缩处理得到1200万像素的目标图像，压缩处理可以是前述均值运算或最大值运算。由于1.5倍的变焦模式对应的视场范围一般小于1倍的变焦模式对应的视场范围，因此，本申请实施方式需要对4800万像素的主原始图像进行裁剪处理得到2100万像素的中间图像，以减小视场范围，再对2100万像素的中间图像进行压缩处理使得电子装置1000输出相较于1倍的变焦模式下，视场范围减小、解析力不变的1200万像素的目标图像。
另外，请参阅图11，在摄像头模组100处于2倍和3倍之间的变焦模式时(例如2.4倍的变焦模式)，处理器200控制主摄像头10获取4800万像素的主原始图像，并对4800万像素的主原始图像进行裁剪处理和放大处理得到1200万像素的目标图像。处理器200具体可以是先对4800万像素的主原始图像进行裁剪处理得到中间图像，再对中间图像进行放大处理得到1200万像素的目标图像。中间图像的像素尺寸可以小于主原始图像的像素尺寸，且小于目标图像的像素尺寸。例如，中间图像的像素尺寸可以是800万像素。处理器200先对4800万像素的主原始图像进行裁剪处理得到800万像素的中间图像，裁剪处理所截取的区域可以是主原始图像最中间的区域，也可以是根据用户输入所确定的区域。然后，处理器200对800万像素的中间图像进行放大处理得到1200万像素的目标图像，放大处理可以是直接通过缩放的方式将图像放大。可以理解，由800万像素的中间图像进行放大处理得到1200 万像素的目标图像，图像解析力略微下降，几乎可以视为解析力不变。由于2.4倍的变焦模式对应的视场范围一般小于1倍的变焦模式对应的视场范围，因此，本申请实施方式需要对4800万像素的主原始图像进行裁剪处理得到800万像素的中间图像，以减小视场范围，再对800万像素的中间图像进行放大处理使得电子装置1000输出相较于1倍的变焦模式下，视场范围减小、解析力几乎不变的1200万像素的目标图像。
请参阅图12，在某些实施方式中，在摄像头模组100处于大于或等于第一预定变焦倍数且小于第二预定变焦倍数的变焦模式时，控制长焦摄像头20以第一长焦距状态获取长焦原始图像，并根据长焦原始图像得到目标图像(即02)，包括：
021：在摄像头模组100处于第三变焦倍数的变焦模式时，控制长焦摄像头20以第一长焦距状态获取长焦原始图像，并对长焦原始图像进行第一图像处理得到目标图像；

请参阅图2，在某些实施方式中，摄像头模组100可以用于执行021、022、023和024中的方法。

本申请实施方式以第三变焦倍数为3倍、第四变焦倍数为4倍为例进行说明。第一长焦距状态可以为长焦摄像头20以3倍光学变焦获取4800万像素的长焦原始图像的状态。
请参阅图13，在摄像头模组100处于3倍的变焦模式时，处理器200控制长焦摄像头20以第一长焦距状态获取4800万像素的长焦原始图像，并对4800万像素的长焦原始图像进行压缩处理得到1200万像素的目标图像。具体地，压缩处理可以是前述均值运算或最大值运算。本申请实施方式通过对4800万像素的长焦原始图像进行压缩处理，电子装置1000可输出相较于3倍的变焦模式下获得的长焦原始图像视场范围不变、且相较于1倍的变焦模式下得到的目标图像解析力不变的1200万像素的目标图像。
请参阅图14，在摄像头模组100处于4倍的变焦模式时，处理器200控制长焦摄像头20以第一长焦距状态获取4800万像素的长焦原始图像，并对4800万像素的长焦原始图像进行裁剪处理和压缩处理得到1200万像素的目标图像。处理器200具体可以是先对4800万像素的长焦原始图像进行裁剪处理得到中间图像，再对中间图像进行压缩处理得到1200万像素的目标图像。中间图像的像素尺寸小于 长焦原始图像的像素尺寸，且大于目标图像的像素尺寸。例如，中间图像的像素尺寸可以是2100万像素。处理器200先对4800万像素的长焦原始图像进行裁剪处理得到2100万像素的中间图像，裁剪处理所截取的区域可以是长焦原始图像最中间的区域，也可以是根据用户输入所确定的区域。然后，处理器200对2100万像素的中间图像进行压缩处理得到1200万像素的目标图像，压缩处理可以是前述均值运算或最大值运算。由于4倍的变焦模式对应的视场范围一般小于3倍的变焦模式对应的视场范围，因此，本申请实施方式需要对4800万像素的长焦原始图像进行裁剪处理得到2100万像素的中间图像，以减小视场范围，再对2100万像素的中间图像进行压缩处理使得电子装置1000可输出相较于3倍的变焦模式视场范围减小、且相较于3倍的变焦模式解析力不变(由于3倍的变焦模式的解析力与1倍的变焦模式的解析力相同，因此此处也是相较于1倍的变焦模式解析力不变)的1200万像素的目标图像。
请参阅图15，在摄像头模组100处于3倍和4倍之间的变焦模式时(例如3.6倍的变焦模式)，处理器200控制长焦摄像头20以第一长焦距状态获取4800万像素的长焦原始图像，并对4800万像素的长焦原始图像进行裁剪处理和压缩处理得到1200万像素的目标图像。处理器200具体可以是先对4800万像素的长焦原始图像进行裁剪处理得到中间图像，再对中间图像进行压缩处理得到1200万像素的目标图像。中间图像的像素尺寸小于长焦原始图像的像素尺寸，且大于目标图像的像素尺寸。例如，中间图像的像素尺寸可以是3400万像素。处理器200先对4800万像素的长焦原始图像进行裁剪处理得到3400万像素的中间图像，裁剪处理所截取的区域可以是长焦原始图像最中间的区域，也可以是根据用户输入所确定的区域。然后，处理器200对3400万像素的中间图像进行压缩处理得到1200万像素的目标图像，压缩处理可以是前述均值运算或最大值运算。由于3.6倍的变焦模式对应的视场范围一般小于3倍的变焦模式对应的视场范围，因此，本申请实施方式需要对4800万像素的长焦原始图像进行裁剪处理得到3400万像素的中间图像，以减小视场范围，再对3400万像素的中间图像进行压缩处理使得电子装置1000可输出相较于3倍的变焦模式视场范围减小、且相较于3倍的变焦模式解析力不变(由于3倍的变焦模式的解析力与1倍的变焦模式的解析力相同，因此此处也是相较于1倍的变焦模式解析力不变)的1200万像素的目标图像。
请参阅图16，在摄像头模组100处于4倍和5倍之间的变焦模式时(例如4.5倍的变焦模式)，处理器200控制长焦摄像头20以第一长焦距状态获取4800万像素的长焦原始图像，并对4800万像素的长焦原始图像进行裁剪处理和压缩处理得到1200万像素的目标图像。处理器200具体可以是先对4800万像素的长焦原始图像进行裁剪处理得到中间图像，再对中间图像进行压缩处理得到1200万像素的目标图像。中间图像的像素尺寸小于长焦原始图像的像素尺寸，且大于目标图像的像素尺寸。例如，中间图像的像素尺寸可以是1900万像素。处理器200先对4800万像素的长焦原始图像进行裁剪处理得到1900万像素的中间图像，裁剪处理所截取的区域可以是长焦原始图像最中间的区域，也可以是根据用户输入所确定的区域。然后，处理器200对1900万像素的中间图像进行压缩处理得到1200万像素的目标图像，压缩处理可以是前述均值运算或最大值运算。由于4.5倍的变焦模式对应的视场范围一般小于3倍的变焦模式对应的视场范围，因此，本申请实施方式需要对4800万像素的长焦原始图像进行裁剪处理得到1900万像素的中间图像，以减小视场范围，再对1900万像素的中间图像进行压缩处理使得电子装置1000可输出相较于3倍的变焦模式视场范围减小、且相较于3倍的变焦模式解析力不变(由于3倍的变焦模式的解析力与1倍的变焦模式的解析力相同，因此此处也是相较于1倍的变焦模式解析力不变)的1200万像素的目标图像。
请参考图17，在某些实施方式中，在摄像头模组100处于大于或等于第二预定变焦倍数的变焦模式时，控制长焦摄像头20以第二长焦距状态获取长焦原始图像，并根据长焦原始图像得到目标图像(即03)，包括：

其中，第五变焦倍数大于或等于第二预定变焦倍数，第六变焦倍数大于第五变焦倍数。
请参考图2，在某些实施方式中，处理器200可以用于执行031、032和033中的方法。
也即是说，处理器200可以用于：在摄像头模组100处于第五变焦倍数的变焦模式时，控制长焦摄像头20以第二长焦距状态获取长焦原始图像，并对长焦原始图像进行第一图像处理得到目标图像； 在摄像头模组100处于第六变焦倍数的变焦模式时，控制长焦摄像头20以第二长焦距状态获取长焦原始图像，并对长焦原始图像进行第二图像处理得到目标图像；和在摄像头模组100处于第五变焦倍数和第六变焦倍数之间的变焦模式时，控制长焦摄像头20以第二长焦距状态获取长焦原始图像，并对长焦原始图像进行第一图像处理和第二图像处理得到目标图像；其中，第五变焦倍数大于或等于第二预定变焦倍数，第六变焦倍数大于第五变焦倍数。
请参考图2，在某些实施方式中，摄像头模组100可以用于执行031、032和033中的方法。
也即是说，在摄像头模组100处于第五变焦倍数的变焦模式时，长焦摄像头20可以以第二长焦距状态获取长焦原始图像，摄像头模组100可以对长焦原始图像进行第一图像处理得到目标图像；在摄像头模组100处于第六变焦倍数的变焦模式时，长焦摄像头20可以以第二长焦距状态获取长焦原始图像，摄像头模组100可以对长焦原始图像进行第二图像处理得到目标图像；在摄像头模组100处于第五变焦倍数和第六变焦倍数之间的变焦模式时，长焦摄像头20可以以第二长焦距状态获取长焦原始图像，摄像头模组100可以对长焦原始图像进行第一图像处理和第二图像处理得到目标图像；其中，第五变焦倍数大于或等于第二预定变焦倍数，第六变焦倍数大于第五变焦倍数。
本申请实施方式以第五变焦倍数为5倍、第六变焦倍数为10倍为例进行说明。第二长焦距状态可以为长焦摄像头20以5倍光学变焦获取4800万像素的长焦原始图像的状态。
请参阅图18，在摄像头模组100处于5倍的变焦模式时，处理器200控制长焦摄像头20以第二长焦距状态获取4800万像素的长焦原始图像，并对4800万像素的长焦原始图像进行压缩处理得到1200万像素的目标图像。具体地，压缩处理可以是前述均值运算或最大值运算。本申请实施方式通过对4800万像素的长焦原始图像进行压缩处理，电子装置1000可输出相较于5倍的变焦模式下获得的长焦原始图像视场范围不变、且相较于1倍的变焦模式下得到的目标图像解析力不变的1200万像素的目标图像。
请参阅图19，在摄像头模组100处于10倍的变焦模式时，处理器200控制长焦摄像头20以第二长焦距状态获取4800万像素的长焦原始图像，并对4800万像素的长焦原始图像进行裁剪处理得到1200万像素的目标图像。由于10倍的变焦模式对应的视场范围一般小于5倍的变焦模式对应的视场范围，因此，本申请实施方式需要对4800万像素的长焦原始图像进行裁剪处理，以减小视场范围，使得电子装置1000输出相较于5倍的变焦模式视场范围减小、且相较于5倍的变焦模式解析力不变(由于5倍的变焦模式的解析力与1倍的变焦模式的解析力相同，因此此处也是相较于1倍的变焦模式解析力不变)的1200万像素的目标图像。其中，裁剪处理所截取的区域可以是长焦原始图像最中间的区域，也可以是根据用户输入所确定的区域。
请参阅图20，在摄像头模组100处于5倍和10倍之间的变焦模式时(例如7倍的变焦模式)，处理器200控制长焦摄像头20以第二长焦距状态获取4800万像素的长焦原始图像，并对4800万像素的长焦原始图像进行裁剪处理和压缩处理得到1200万像素的目标图像。处理器200具体可以是先对4800万像素的长焦原始图像进行裁剪处理得到中间图像，再对中间图像进行压缩处理得到1200万像素的目标图像。中间图像的像素尺寸小于长焦原始图像的像素尺寸，且大于目标图像的像素尺寸。例如，中间图像的像素尺寸可以是1900万像素。处理器200先对4800万像素的长焦原始图像进行裁剪处理得到1900万像素的中间图像，裁剪处理所截取的区域可以是长焦原始图像最中间的区域，也可以是根据用户输入所确定的区域。然后，处理器200对1900万像素的中间图像进行压缩处理得到1200万像素的目标图像，压缩处理可以是前述均值运算或最大值运算。由于7倍的变焦模式对应的视场范围一般小于5倍的变焦模式对应的视场范围，因此，本申请实施方式需要对4800万像素的长焦原始图像进行裁剪处理得到1900万像素的中间图像，以减小视场范围，再对1900万像素的中间图像进行压缩处理使得电子装置1000可输出相较于5倍的变焦模式视场范围减小、且相较于5倍的变焦模式解析力不变(由于5倍的变焦模式的解析力与1倍的变焦模式的解析力相同，因此此处也是相较于1倍的变焦模式解析力不变)的1200万像素的目标图像。
综上，本申请实施方式的变焦方法和电子装置1000通过设置第一预定变焦倍数和第二预定变焦倍数，在摄像头模组100处于小于第一预定变焦倍数的变焦模式、大于或等于第一预定变焦倍数且小于第二预定变焦倍数的变焦模式、以及大于或等于第二预定变焦倍数的变焦模式时，分别进行不同的图像处理，从而能够保证全焦段输出的目标图像的解析力不变，提高成像性能(即全程光学性能都是无损的，实现了光学的无损线性变焦)。
