Description

一种展现移动终端拍摄的图像的方法及装置 本申请要求于 2013 年 3 月 26 日提交中国国家知识产权局、 申请号为 201310100001.9、 发明名称为 "一种展现移动终端拍摄的图像的方法及装置" 的中国专利申请的优先权， 该在先申请的全部内容通过 ^ ]用结合在本申请中。 技术领域 本申请涉及信息处理技术领域，特别涉及一种展现移动终端拍摄的图像的 方法及其对应的装置。
背景技术
随着移动通信技术的发展，移动终端已集成了相机拍摄功能， 用户通过操 作移动终端可以启动相机应用程序拍摄自己需要的图像。 为了便于阅读和查 看， 移动终端拍摄的图像在展现时通常具有方向属性。 比如， 对于利用移动终 端拍摄的文字型图像（即拍摄文本材料形成的图像）， 由于阅读文字的习惯是 自上而下、 自左而右， 那么在拍摄文字材料之时或者之后， 必须向相机应用程 序传递方向参数， 以便相机应用程序按照正确的方向存储图像， 或者在展现图 像时利用该方向参数进行正确的展现。 由此可见， 为了正确阅读或查看移动终 端拍摄的图像， 需要获取到拍摄对象的方向信息。
现有技术获取拍摄对象方向信息是通过内置于移动终端中的重力感应装 置实现的。 重力传感装置通常包括 "重力块" 和 "压电晶体"， 当移动终端的 方向改变时， "重力块" 作用于 "压电晶体" 的力随之改变， 从而输出不同的 电压信号，依据该电压信号即可判断移动终端所处的方向，移动终端的方向作 为拍摄对象的方向信息传递给相机应用程序，相机应用程序即可根据这个方向 信息存储、 展现拍摄的图像。
然而，限于重力传感装置的依赖重力的工作原理以及生产技术带来的精度 范围， 当移动终端处于水平状态或者与水平面存在某个预设范围内的夹角时， 重力传感装置将无法正确识别方向，使移动设备拍摄的图像没有明确的方向属 性， 从而影响到对图像的正确展现， 给阅读或查看带来不便。

附图说明
实施例或现有技术描述中所需要使用的附图作简单地介绍。 显而易见地， 以下描述中的附图仅仅是本发明的一些实施例， 对于本领域普通技术人 员而言， 还可以根据这些附图所示实施例得到其它的实施例及其附图。

图 3为本申请的展现移动终端拍摄的图像的方法再一个实施例的流程图； 图 4 ( a ) 为在移动终端的取景区内呈现方向属性信息的方式之一； 图 4 ( b ) 为在移动终端的取景区内呈现方向属性信息的方式之二； 图 5为本申请的展现移动终端拍摄的图像的装置实施例的结构框图。
具体实施方式 为了使本技术领域的人员更好地理解本申请中的技术方案，下面将结合本 申请实施例中的附图， 对本申请实施例中的技术方案进行清楚、 完整地描述， 显然， 所描述的实施例仅仅是本申请一部分实施例， 而不是全部的实施例。 基 于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获 得的所有其他实施例， 都应当属于本申请保护的范围。
参见图 1 , 该图示出了本申请的展现移动终端拍摄的图像的方法的一个实 施例 （基石出实施例） 的流程。 该实施例包括：
步骤 S101 : 判断移动终端面板所在平面偏离水平面的程度是否在预设范 围内， 如果是， 执行步骤 S102; 如果否， 则执行步骤 S105;
移动终端通常为矩形块形式， 其具有面板和侧壁。根据面板所在平面与水 平面之间的关系，在利用移动终端进行拍摄过程中，移动终端的空间状态可以 划分两种基本类型， 即竖直状态和水平状态： 移动终端在竖直状态下， 移动终 端的面板所在平面与水平面之间的夹角为 90。 ； 移动终端在水平状态下， 移 动终端的面板所在平面与水平面之间的夹角为 0° 。 除这两种基本的移动终端 空间状态外， 在拍摄过程中， 为适应拍摄或个人喜好的需要， 还可以存在处于 这两种状态之间的状态，即移动终端面板所在平面与水平面之间存在一定的夹 角。 为了涵盖移动终端在拍摄过程中各种空间状态，将这种移动终端面板所在 平面与水平面之间的关系称为偏离程度。在使用移动终端启动拍摄功能后， 本 实施例首先判断移动终端面板所在平面偏离水平面的偏离程度是否在预设范 围， 根据偏离程度不同， 采取不同的措施实现对移动终端拍摄的图像的展现， 这里的预设范围可根据实际情况进行设定， 其取决于移动终端本身的性能、移 动终端内方向判别设备的精度、 灵敏度以及移动终端用户自身的喜好等因素。 需要说明的是： 这里的面板可以是移动终端的上面板， 也可以是下面板， 本实 施例给出 "面板"这一术语旨在确定移动终端相对于水平面的偏离程度， 并不 用于限定移动终端的结构形状、 材质组成等。
步骤 S102: 通过移动终端的相机应用程序提示拍摄对象的方向属性信息； 通过前述步骤确定移动终端面板所在平面偏离水平面的程度在预设范围 内时， 本实施例提供接收拍摄对象方向属性的入口，通过相机应用程序在移动 终端屏幕上显示拍摄对象的方向属性信息。接收方向属性的入口可以通过多种 具体形式体现出来： 比如，在相机应用程序中编写程序使其在移动终端屏幕上 显示对话框， 请求用户输入拍摄对象的方向属性； 还比如， 通过软件方式将移 动终端侧壁上的音量调节按钮设置为方向属性的触发控键，通过对触发控键的 物理操作产生拍摄对象的方向属性信息； 再比如，在屏幕中直接显示多个箭头 标识，通过识别箭头标识的触发情况来获得拍摄对象的方向属性信息。 为便于 理解本实施例的技术方案， 下面对拍摄对象的方向属性的概念作简要解释： 拍 摄对象的方向属性是指在拍摄设备对拍摄对象进行拍摄后形成的图像中符合 阅读或查看习惯的哪个方向，拍摄对象的方向属性信息指至少包含拍摄对象方 向属性在内的方向信息的集合。 以图 2所示文字型材料（拍摄对象）为例， 图 2是未拍摄前拍摄对象在移动终端取景区的情形， 在该文字型材料中符合阅读 或查看习惯的为正东向， "正东向" 即为该文字型材料的方向属性， 但基于实 际应用需要， 可以给出正东、 正西等方向作为方向属性信息供用户选择确认。
步骤 S 103 : 接收对拍摄对象方向属性信息的选定结果；
当通过相机应用程序提示出来的拍摄对象的方向属性信息后，需要确定一 个用于呈现对拍摄对象进行拍摄后形成的图片的方向，当提示出的拍摄对象的 方向属性信息包含多个方向属性时，从中选择一个方向属性作为结果（对于移 动终端或移动终端所在的相机应用程序等而言，即接收对拍摄对象方向属性信 息的选定结果）； 当提示出的拍摄对象的方向属性信息包含一个方向属性时， 选定该方向属性即可获得对拍摄对象方向属性信息的选定结果。
步骤 S 104: 在完成拍摄操作后根据所述选定结果展现移动终端拍摄的图 像， 结束流程； 在完成拍摄操作需要展现对拍摄对象的拍摄的图片时， 根据前 述步骤确定的方向属性的选定结果展现拍摄图像。
步骤 S 105: 通过重力感应装置确定拍摄对象的方向属性；
通过 S 101步骤确定移动终端面板所在平面偏离水平面的程度在预设范围 之外时， 可以仍然采用原有的方式确定拍摄图像的方向属性。 比如， 采用重力 感应装置确定拍摄对象的方向属性。 以移动终端对前方的一个人进行拍摄为 例， 当重力感应装置感应到在竖直方向上的重力加速度值为 9.8 , 则说明移动 终端的空间状态为竖直状态， 由于是在竖直方向上拍摄人， 因此， 竖直朝上即 为人的 "人头" 方向， 该方向即为拍摄对象的方向属性， 按照该方向展现拍摄 的图片即为符合浏览或查看习惯的方向。
步骤 S 106: 根据所述重力感应装置确定的拍摄对象的方向属性展现移动 终端拍摄的图像， 结束流程。
本实施例先判断移动终端面板所在平面偏离水平面的程度是否在预设范 围内， 如果在预设范围内便通过相机应用程序提示拍摄对象的方向属性信息， 然后根据用户对拍摄对象方向属性信息的选择结果对移动终端拍摄的图像进 行展现。 与现有技术相比， 本申请实施例将对移动终端拍摄的图像进行展现的 方式划分为两个类别： 一是移动终端面板所在平面与水平面偏离程度较大时， 即移动终端处于竖直或基本竖直时，由于重力感应装置能够识别拍摄对象的方 向，在对移动终端拍摄的图像进行展现时即可按照该方向进行展现； 二是移动 终端所在平面与水平面偏离程度较小时，即移动终端处于水平状态或接近水平 状态时， 不在通过重力感应装置识别拍摄对象的方向， 而是提供入口接收用户 对拍摄对象方向属性信息的选择结果，在对移动终端拍摄的图像进行展现时即 可按照这个选择结果表明的方向进行展现。通过这种依据不同情况采取不同的 展现方式使展现出来的移动终端的拍摄图像始终符合阅读或查看的需要，从而 提高便利性。
尽管上述方法实施例已能解决本申请的技术问题， 实现发明目的，每个步 骤具有多种具体的实现方式。 为了更加明确本申请的技术特征， 下面给出一种 更加优选的实施例。 参见图 3 , 该图示出了该优选实施例的流程。 该优选实施 例包括：
步骤 S301 : 分别获取重力感应装置测得的 X轴、 Υ轴向上的重力加速度 值， 所述 X轴、 Υ轴组成的平面为水平面；
为便于对移动终端面板所在平面与水平面的偏离程度进行衡量，本优选实 施例利用重力感应装置实现。 重力感应装置的测量需基于一定的坐标系， 本优 选实施例以水平方向的一个方向为 X轴， 在水平面上与 X轴垂直的方向为 Υ 轴， 与 X、 Υ轴构成的平面垂直的方向为 Ζ轴。 在这样的坐标系中， 通过重力 感应装置分别测量获得 X轴、 Υ轴向上的重力加速度值。
步骤 S302:判断 X轴向上的重力加速度值是否小于第一预设加速度阀值， 且 Υ轴向上的重力加速度值是否小于第二预设加速度阀值， 如果是， 则确定 移动终端所在平面偏离水平面的程度在预设范围内， 执行步骤 S303; 如果否， 则确定移动终端面板所在平面偏离水平面的程度未在预设范围内， 执行步骤 S307„
通过前述步骤测得 X、 Y轴向上的重力加速度值后， 将这两个方向上的加 速度值与预设的加速度阀值进行比较， 如果比较结果均小于预设加速度阀值， 则表明当前移动终端面板所在平面相对于水平面的偏离程度在预设范围内，移 动终端当前所处的空间状态将使通过重力感应装置无法进行拍摄对象的方向 属性的识别； 如果比较结果有其一或者两个均大于预设加速度阀值， 则表明当 前移动终端面板所在平面相对于水平面的偏离程度未在预设范围内 ,移动终端 当前所处的空间状态不影响通过重力感应装置对拍摄对象的方向属性进行识 别。 比如， 以第一、 第二预设加速度阀值均为 4.9[9.8 Math. sin ( Math, π /6 ) ] 为例， 当 Math.abs(xAxisValue) < 4.9 and Math. abs(yAxis Value) < 4.9 时 ( xAxis Value代表的重力加速度在 x轴上的分量， yAxisValue代表重力加速度
30° 倾角。 在该范围内， 通过重力感应装置将无法确定拍摄对象的方向属性。
步骤 S303: 在移动终端对拍摄对象的取景框内， 呈现 N个方向的箭头， 所述 N个方向的箭头两两之间的夹角为相同或不相同的预设角度值， 所述 N 为大于等于 4的自然数；
当通过前述步骤确定移动终端的空间状态在预设偏离程度范围内时，在移 动终端相机应用程序对拍摄对象的取景框内， 呈现出 N个方向的箭头， 这 N 个箭头中有一个方向是满足用户正常浏览或查看图像要求的，Ν个箭头的方向 两两之间的夹角可以相等（等距离分布）也可以不相等（非等距离分布）， 通 常情况下 Ν大于等于 4。 参见图 4, 图 4 ( a )示出了 Ν等于 4, 四个箭头的方 向分别为正东、 正西、 正南、 正北的方向属性信息提示情形； 图 4 ( b ) 示出 了 N等于 8, 八个箭头的方向除正东、正西、正南、正北方向外，还包括东南、 西南、 东北、西北四个反向。通常情况，方向越多越能满足用户的个性化需求， 比如某些用户希望展现出来的图片与展现屏幕存在一定的偏角，但是， 方向越 多在取景区占用的面积越大，可能引起屏幕图标的臃肿，影响正常的取景拍摄。 一种较好的方式是综合这两方面的需求根据具体情况进行决定提示方向的数 量。 比如， 由相机应用程序提供设置入口供用户在启动拍摄功能之前设置， 数 量设置为 4, 方向设置为东西南北四正方向。
步骤 S304: 接收所述 N个方向中的一个方向的选定结果；
步骤 S305: 存储移动终端拍摄的图像时存储与该图像对应的方向属性信 息的选择结果； 通过前述步骤选定的方向属性是最终用于展现图片的， 可以单 独建立一个文件记录与拍摄对象对应的方向属性信息；
步骤 S306: 读取存储的移动终端的图像和与该图像对应的方向属性信息 的选择结果， 根据所述选择结果对移动终端拍摄的图像进行展现， 结束流程； 当接收到展现触发请求后，同时读出存储的移动终端拍摄的图像和该图像 对应的方向属性 ,然后根据该方向属性对拍摄的图形进行展现。值得强调的是： 除按照上述步骤 S305、 306的方式展现图像外， 实际上还可以在存储移动终端 拍摄的图像时直接按照选定的方向属性进行存储，这样在接收到展现触发请求 时， 可以直接读取按照方向属性存储的图像进行展现。这里按照选定的方向属 性进行存储可以通过相机应用程序调用 setRotation ( )函数对拍摄到的图像按 照选定的方向 （角度）进行旋转， 然后将旋转后的图像进行存储。 setRotation ( ) 函数属于 android. hardware. Camera. Parameters包, 用于设置相对于相机方 向的顺时针旋转角度， 此角度是相对相机传感器 (camera sensor)方向的角度。 比如后置相机传感器被固定与任意方向。
步骤 S307: 通过重力感应装置确定拍摄对象的方向属性；
步骤 S308: 根据所述重力感应装置确定的拍摄对象的方向属性展现移动 终端拍摄的图像， 结束流程。 平面的程度是否在预设范围内、通过移动终端的相机应用程序提示拍摄对象的 方向信息以及根据选定结果展现移动终端拍摄的图像的优选方式，且将这些优 选方式组合成一个优选实施例，但是， 这并不表明这些优选的方式不能以独立 的形式存在， 也就是说， 在本申请基本实施例基础上， 可以将对其中的某个步 骤或几个步骤的优选方式与其他步骤组成成一个实施例。 上述内容详细叙述了本申请的自拍图像的展现方法的实施例，相应地， 本 申请还提供了一种展现移动终端拍摄的图像的装置实施例。 参见图 5 , 该图示 出了本申请的展现移动终端拍摄的图像的装置实施例的结构框图。该实施例装 置包括： 判断单元 501、 提示单元 502、 接收单元 503和展现单元 504, 其中： 判断单元 501 , 用于判断移动终端所在平面偏离水平面的程度是否在预设 范围内， 如果是， 则触发提示单元；
提示单元 502, 用于通过移动终端的相机应用程序提示拍摄对象的方向属 性信息；
接收单元 503 , 用于接收对拍摄对象方向属性信息的选定结果；
展现单元 504, 用于根据所述选定结果展现移动终端拍摄的图像。
本装置实施例的工作过程是：先由判断单元 501判断移动终端所在平面偏 离水平面的程度是否在预设范围内， 如果是， 则触发提示单元 502, 由提示单 元 502通过移动终端的相机应用程序提示拍摄对象的方向属性信息；接收单元 503在接收对拍摄对象方向属性信息的选择结果后， 展现单元 504根据所述选 择结果展现移动终端拍摄的图像。
本装置实施例先判断移动终端面板所在平面偏离水平面的程度是否在预 设范围内，如果在预设范围内便通过相机应用程序提示拍摄对象的方向属性信 息，然后根据用户对拍摄对象方向属性信息的选择结果对移动终端拍摄的图像 进行展现。 与现有技术相比， 本装置实施例将对移动终端拍摄的图像进行展现 的方式划分为两个类别： 一是移动终端面板所在平面与水平面偏离程度较大 时， 即移动终端处于竖直或基本竖直时， 由于重力感应装置能够识别拍摄对象 的方向，在对移动终端拍摄的图像进行展现时即可按照该方向进行展现； 二是 移动终端所在平面与水平面偏离程度较小时，即移动终端处于水平状态或接近 水平状态时， 不在通过重力感应装置识别拍摄对象的方向， 而是提供入口接收 用户对拍摄对象方向属性信息的选择结果，在对移动终端拍摄的图像进行展现 时即可按照这个选择结果表明的方向进行展现。通过这种依据不同情况采取不 同的展现方式^^现出来的移动终端的拍摄图像始终符合阅读或查看的需要， 从而提高便利性。
上述装置实施例中的判断单元根据其对移动终端所在平面偏离水平面的 程度的不同判断方式可以具有不同的内部结构。 比如， 本申请优选判断单元 501可以包括加速度值获取子单元 5011、 加速度值判断子单元 5012和偏离程 度确定子单元 5013 , 其中：
加速度值获取子单元 5011 , 用于分别获取重力感应装置测得 X轴、 Y轴 向上的重力加速度值， 所述 X轴、 Y轴组成的平面为水平面； 加速度值判断子单元 5012, 用于判断 X轴向上的重力加速度值是否小于 第一预设加速度阀值， 且 Y轴向上的重力加速度值是否小于第二预设加速度 阀值， 如果是， 则触发偏离程度确定子单元；
偏离程度确定子单元 5013 , 用于确定移动终端所在平面偏离水平面的程 度在预设范围内。
基于同样的道理，上述装置实施例的提示单元 502基于其不同的提示方式 也可以具有不同的内部结构。 比如， 本申请优选提示单元 502可以包括箭头呈 现子单元 5021 ,用于在移动终端对拍摄对应的取景框内呈现 N个方向的箭头 , 大于等于 4的自然数， 作为一种实用的提示方式， N可以取 4, 4个方向的箭 头可以为正东、 正西、 正北、 正南。 这种情况下， 接收单元 503具体用于接收 所述 N个方向中的一个方向的选择结果。
上述装置实施例的展现单元基于不同的展示方式也具有不同内部结构。比 如， 展现单元 504的一种结构组成可以是包括： 第一存储子单元 5041、 第一 读取子单元 5042和第一展现子单元 5043 , 其中： 第一存储子单元 5041 , 用于 在存储移动终端拍摄的图像时存储与该图像对应的方向属性信息的选择结果； 第一读取子单元 5042, 用于读取存储的移动终端的图像和与该图像对应的方 向属性信息的选择结果； 第一展现子单元 5043 , 用于根据所述选择结果对移 动终端拍摄的图像进行展现。还比如，展现单元 504的另一种结构组成可以是 包括： 第二存储子单元和第二展现子单元， 其中： 所述第二存储子单元， 用于 根据所述对拍摄对象方向属性信息的选择结果存储移动终端拍摄的图像；所述 第二展现子单元， 用于读取存储的移动终端拍摄的图像并进行展现。上述两种 展现单元的组成方式各有优缺点，对于第一种组成方式而言， 由于存储时对移 动终端拍摄的图像可以不经过任何处理直接进行存储， 有利于节约存储时间， 但在具体展现时需要同时读取拍摄的图像和接收的与该图像对应的方向属性 信息的选择结果， 从而减緩了展示速度； 对于第二种组成方式， 由于在存储之 前需要对拍摄的图像进行适当处理，增加了存储时间，但在具体展现时可直接 读取经过处理操作后的拍摄图像进行展现。在实际应用过程中， 可根据应用需 要和关注点的差异选择恰当的展示单元的结构组成形式。 需要说明的是： 为了叙述的简便， 本说明书的上述实施例以及实施例的各 种变形方式重点说明的都是与其他实施例或变形方式的不同之处，各个情形之 间相同相似的部分互相参见即可。尤其，对于装置实施例的几个改进方式而言， 由于其基本相似于方法实施例， 所以描述得比较简单，相关之处参见方法实施 例的部分说明即可。以上所描述的装置实施例的各单元可以是或者也可以不是 物理上分开的， 既可以位于一个地方， 或者也可以分布到多个网络环境下。 在 实际应用过程中，可以根据实际的需要选择其中的部分或者全部单元来实现本 实施例方案的目的， 本领域普通技术人员在不付出创造性劳动的情况下， 即可 以理解并实施。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通 技术人员来说， 在不脱离本申请原理的前提下， 还可以做出若干改进和润饰， 这些改进和润饰也应视为本申请的保护范围。
