 背景技术
目前的数码摄影产品基本上都具备有自动对焦和图像连拍等功能，一般情况数码摄影产品拍照应用中包含几种拍照模式，例如连拍模式、防抖模式、延迟模式等，默认为普通模式，其他模式需在拍照前选择。以手机为例，目前触屏手机上垂直连拍应用采取的连拍交互方式与单反相机连拍方式类似：若短按（Short Pressed）拍照按钮，拍照一张；若长按（Long Pressed）拍照按钮，连续拍照直至手指抬起（Moved Up）。如图1所示现有技术中快速连拍相机示意图，包括取景区11以及拍照按钮12，单击拍照按钮12拍照一张，若长按拍照按钮12则对取景区11内的图像进行连拍操作。
然而，现有技术存在以下不足之处：默认拍照模式为普通模式，连拍模式需在拍照前选择，使得连拍操作的设置过程繁琐；如使用者不小心触压到拍照按钮即开始连续拍照直至手指抬起，由此造成的误操作难以及时纠错，后期照片删除成本大；而且对于体积较大的数码摄影产品，使用者无法准确的按压拍照按钮完成连拍操作。
综上，需解决现有技术中存在的连拍操作的设置过程繁琐，按压拍照按钮进行连拍操作的拍照方式操作不便，以及误操作难以及时纠错的技术问题。

本发明的目的在于提供一种图像获取方法、装置及计算机可读存储介质，其能简化触屏拍摄中图像连拍操作的设置过程，并在发生误操作时能及时纠错，增加操作准确度，提供更快速的图像连拍方式，扩大图像连拍的应用范围。

首先结合附图给出本发明的图像获取方法及装置的优选实施方式。
附图2所示是本优选实施方式所述图像获取方法的流程图，附图3为本发明的图像获取装置一优选实施方式的架构图。
本发明实施例的图像获取装置包括接收单元31、第一判断单元32、第二判断单元33、显示单元34以及图像获取单元35。
在步骤201中，所述接收单元31在图像获取界面屏幕上的同一区域接收到触摸动作，即，所述接收单元31在图像获取界面屏幕上的同一区域接收用户的操作指令，其中所述操作指令与所述用户的触摸动作对应。
具体地，在打开图像功能进入图像获取界面后，所述接收单元31在图像获取界面屏幕上的任何部分都可以接收触摸动作，进入触屏拍摄的程序；当同一区域接收到触摸动作后，可以直接进行连拍操作判断，无需启动拍照模式设置应用进行连拍模式设置。
通过调研发现，现有技术中按压拍照按钮进行连拍操作的不便，主要的原因是由于连拍模式需要在拍照模式设置应用中进行连拍模式设置，而且现有的数码摄影产品拍照按钮过于靠下，不适宜大触摸屏数码摄影产品（如4~5.3英寸手机）的单手操作，其底部拍照按钮的点击操作不符合人体工效学设计，拇指弯曲曲度较大，且不利于数码摄影产品的稳固握持。而通过本发明提供的技术方案，当数码摄影产品打开图像功能并进入图像获取界面后，屏幕上取景区域的任何部分都可以接收触摸动作，进入触屏拍摄的程序；当屏幕上同一区域接收到触摸动作，可以直接进行连拍操作判断，无需启动拍照模式设置应用进行连拍模式设置，简化了连拍操作的设置过程。
在步骤202中，所述第一判断单元32根据所述操作指令，判断所述触摸动作的第一持续时间是否等于（相同于）或大于一预设的第一准备时间，若所述第一持续时间相同于或大于所述第一准备时间，则执行步骤203。其中，所述第一准备时间可以根据实际需要设置为处于0.1s（Seconds，秒）至0.3s的范围内，优选为0.2s。
在所述屏幕的同一区域接收到触摸动作后，进入第一准备状态，所述第一准备状态具有一预设的第一准备时间。可以根据实际拍摄需求预先设定第一准备时间，以在所述屏幕的同一区域接收到触摸动作后，根据第一准备时间对第一准备状态进行计时操作，计时结果即为第一持续时间，以确认此次触摸动作为拍摄操作，从而防止误操作。当所述第一持续时间的计时结果小于所述第一准备时间，即所述同一区域的触摸动作在所述第一准备时间内中断，则退出第一准备状态，并进一步判断是否发生不同区域的触摸动作（例如滑动操作）；若发生不同区域的触摸动作则根据所述不同区域的触摸动作执行相应操作；若所述第一持续时间相同于或大于所述第一准备时间则执行步骤203。
现有的具有连拍功能的数码摄影产品，在连拍模式下，若用户不小心触到拍照按钮即开始连续拍照直至手指抬起，由于连拍前没有设置等待确认时间，因此发生误操作后难以及时纠错。本发明通过设置准备时间，可以在发生误操作时能及时纠错，增加了操作准确度；即在第一准备时间内，使用者随时可以通过滑动操作或抬起操作，取消连拍程序的进行，从而有效避免误操作，提高连拍操作的准确性，有效减少后期删除照片的成本。
在步骤203中，若所述第一持续时间等于或大于所述第一准备时间，所述显示单元34显示计时提示信息，并判断所述触摸动作的第二持续时间是否相同于或大于一预设的第二准备时间，若所述第二持续时间相同于或大于所述第二准备时间，则执行步骤204，否则执行步骤205。其中，所述第二准备时间可以根据实际需要设置为处于0.3s至1s的范围内，优选为0.5s。
所述计时提示信息可以为图片、文字、语音以及动画信息。所述显示单元34显示计时提示信息的步骤包括：所述显示单元34播放一时长等于所述第二持续时间的动画。例如显示圆环以顺时针方向匀速旋转，逐渐形成一闭合圆环，圆环出现到闭合的时间等于所述第二准备时间；若所述第二持续时间相同于或大于所述第二准备时间，则播放一完整的旋转圆环动画，否则第二持续时间截止，旋转圆环播放动画结束。长按的计时提示信息除了旋转圆环外，还可以是旋转圆饼或其他可以表示时间进度的视觉反馈计时提示信息。通过播放计时动画，可以提示使用者当前已经入连拍的程序，如使用者不需要对当前取景区域内的图像进行连拍，则取消对触控屏幕的按压触控，从而终止此次图像获取操作，有效减少误操作。
在判定所述第一持续时间相同于或大于所述第一准备时间后，进入一第二准备状态，所述第二准备状态具有一预设的第二准备时间。根据实际拍摄需求预先设定第二准备时间，以在判定所述第一持续时间相同于或大于所述第一准备时间后，所述第二判断单元33根据第二准备时间对第二准备状态进行计时操作，计时结果即为第二持续时间，同时通过显示计时信息提示使用者，以进一步确认此次触摸动作为连拍操作，从而提高连拍操作的准确度，进一步防止误操作。若在第二准备状态期间，所述同一区域的触摸动作没有中断，即第二准备状态的计时结果相同于或大于第二准备时间，则执行步骤204。
在步骤204中，若所述第二持续时间等于或大于所述第二准备时间，所述图像获取单元35按照预设的时间间隔周期性的获取相应的图像。其中，所述预设的时间间隔为预先设定的连续的两次拍摄的时间间隔，可以根据实际需要设置时间间隔为处于0.1s至0.3s的范围内。根据预设的时间间隔，周期性的执行相应的图像的获取操作，实现连拍操作。
在步骤205中，若所述第二持续时间小于所述第二准备时间，所述图像获取单元35执行相应的图像的单次获取操作。在其他实施方式中，若所述第二持续时间小于所述第二准备时间，可以选择退出第二准备状态，返回步骤201重新开始等待接收图像获取界面屏幕上的同一区域的触摸动作，或者判断是否发生不同区域的触摸动作（例如滑动操作），并进行相应操作的执行。
在其他实施方式中，所述图像获取装置还可以包括检测单元36，在步骤204之后，还可以执行步骤206。
在步骤206中，所述检测单元36检测所述触摸动作是否结束，若是，则所述图像获取单元35终止获取图像的动作；否则继续执行步骤204，即，所述图像获取单元35继续按照预设的时间间隔周期性地获取相应的图像。
在所述的图像获取设备在进行图像连拍时，预先设定了进行图像连拍，若连续的两次拍摄的时间间隔为150ms（毫秒），则在第二准备状态结束后，每150ms执行一次图像获取操作，直到所述触摸动作结束，则结束连拍操作。比如若在第二准备状态结束后所述触摸动作持续时间为140ms，则此次连拍操作共拍摄了1次，获取了1张图像；若第二持续时间为1500ms，则此次连拍操作共拍摄了11次，获取了11张图像。
通过上述方法，使用者通过点击按压取景框内任何区域的触摸屏即可启动拍照程序，通过长按该区域即可实现连拍操作，无需对图像获取设备进行连拍模式选择设置，简化了连拍操作的设置过程，提供更快速的连拍操作方式，扩大连拍的应用范围；通过准备时间的设置与判断以及显示计时信息，使得该次连拍操作是在使用者确认情况下完成的，从而有效避免误操作，提高连拍操作的准确性，有效减少后期删除照片的成本。
在其他实施方式中，所述图像获取装置还可以包括自动对焦单元（自动对焦模块）37，在所述屏幕上的同一区域接收到触摸动作后，且在判断所述第二持续时间是否相同于或大于所述第二准备时间之前，所述方法还包括步骤：所述自动对焦单元37获取所述触摸动作对应的位置坐标，将图像获取操作的焦点设置于所述位置坐标处；从而实现了取景区域内任意屏幕位置的局部对焦的功能。
接下来结合附图给出本发明所述图像获取装置的优选实施方式。
附图3所示是本优选实施方式所述图像获取装置的架构图。
所述接收单元31用于接收图像获取界面屏幕上的同一区域的触摸动作，即，所述接收单元31用于在图像获取界面屏幕上的同一区域接收用户的操作指令，其中所述操作指令与所述用户的触摸动作对应。在打开图像功能进入图像获取界面后，通过所述接收单元31接收图像获取界面屏幕上的任何部分的触摸动作对应的所述操作指令，进入触屏拍摄的程序；当通过所述接收单元31接收到同一区域的触摸动作后，可以直接进行连拍操作判断，无需启动拍照模式设置应用进行连拍模式设置，简化了连拍操作的设置过程。
所述第一判断单元32用于根据所述操作指令，判断所述触摸动作的第一持续时间是否等于（相同于）或大于一预设的第一准备时间，若所述第一持续时间相同于或大于所述第一准备时间则执行所述第二判断单元33；其中，所述第一准备时间可以根据实际需要设置为处于0.1s至0.3s的范围内，优选为0.2s。
在所述接收单元31接收到屏幕的同一区域的触摸动作后，进入第一准备状态，所述第一准备状态具有一预设的第一准备时间。可以根据实际拍摄需求预先设定第一准备时间，以在所述屏幕的同一区域接收到触摸动作后，根据第一准备时间对第一准备状态进行计时操作，计时结果即为第一持续时间，以确认此次触摸动作为拍摄操作，从而防止误操作。
当所述第一持续时间的计时结果小于所述第一准备时间，即所述同一区域的触摸动作在所述第一准备时间内中断，则退出第一准备状态，并进一步判断是否发生不同区域的触摸动作（例如滑动操作）；若发生不同区域的触摸动作则根据所述不同区域的触摸动作执行相应操作；若所述第一持续时间相同于或大于所述第一准备时间则执行所述第二判断单元33。
若所述第一持续时间相同于或大于所述第一准备时间，所述第二判断单元33用于判断所述触摸动作的第二持续时间是否相同于或大于一预设的第二准备时间，若所述第二持续时间相同于或大于所述第二准备时间，则通过图像获取单元35按照预设的时间间隔周期性的获取相应的图像。其中，所述第二准备时间可以根据实际需要设置为处于0.3s至1s的范围内，优选为0.5s。
所述显示单元34用于在所述第二判断单元33执行判断步骤的同时显示计时提示信息，即，所述显示单元34用于在所述第一持续时间等于或大于所述第一准备时间时，显示计时提示信息。所述显示单元34显示计时提示信息包括：播放一时长等于所述第二持续时间的动画。例如显示圆环以顺时针方向匀速旋转，逐渐形成一闭合圆环，圆环出现到闭合的时间等于所述第二准备时间；若所述第二持续时间相同于或大于所述第二准备时间，则播放一完整的旋转圆环动画，否则第二持续时间截止，旋转圆环播放动画结束。
长按的计时提示信息除了旋转圆环外，还可以是旋转圆饼或其他可以表示时间进度的视觉反馈计时提示信息。通过播放计时动画，可以提示使用者当前已经入连拍程序，如使用者不需要对当前取景区域内的图像进行连拍，则可以通过取消对触控屏幕的按压触控，从而终止此次图像获取操作，有效减少误操作。
在判定所述第一持续时间相同于或大于所述第一准备时间后，获取相应的图像之前，进入一第二准备状态，所述第二准备状态具有一预设的第二准备时间。根据实际拍摄需求预先设定第二准备时间，以在判定所述第一持续时间相同于或大于所述第一准备时间后，根据第二准备时间对第二准备状态进行计时操作，计时结果即为第二持续时间，同时通过显示单元34显示计时信息提示使用者，以进一步确认此次触摸动作为连拍操作，从而进一步防止误操作。若在第二准备状态期间，所述同一区域的触摸动作没有中断，即第二准备状态的计时结果相同于或大于第二准备时间，则控制所述图像获取单元35执行图像获取操作。
所述图像获取单元35用于获取相应的图像。例如，若所述第二持续时间等于或大于所述第二准备时间，按照预设的时间间隔周期性的获取相应的图像，实现连拍操作。其中，所述预设的时间间隔为预先设定的连续的两次拍摄的时间间隔，可以根据实际需要设置时间间隔为处于0.1s至0.3s的范围内。所述图像获取单元35根据预设的时间间隔，周期性的执行相应的图像的获取操作。
在其他实施方式中，若所述第二持续时间小于所述第二准备时间，所述图像获取单元35还用于：执行相应的图像的单次获取操作，获取一张图像。
在其他实施方式中，所述图像获取装置还包括检测单元36，用于检测所述触摸动作是否结束，若是，则所述图像获取单元35还用于终止执行所述图像获取单元35；否则，所述图像获取单元35还用于继续通过所述图像获取单元35按照预设的时间间隔周期性的获取相应的图像。
在其他实施方式中，所述图像获取装置还包括自动对焦模块（自动对焦单元）37。在所述接收单元31接收到图像获取界面屏幕上的同一区域的触摸动作后，所述自动对焦单元37用于获取所述触摸动作对应的位置坐标，将图像获取操作的焦点设置于所述位置坐标处；从而实现了取景区域内任意屏幕位置的局部对焦的功能。
接下来结合附图给出上述技术方案的优选实施例。
参考图4、图5和图6，图4为本实施例所述的本发明显示计时提示信息的示意图，图5为图4中计时提示信息的动画显示示意图；图6为本实施例所述的本发明图像连拍控制方法的流程图。图4中，打开图像功能进入拍照状态后，取景区41内所有区域的触摸屏均可等待屏幕按压事件，按压取景区41即可进入连拍操作，不需要进行拍照模式设置；长按取景区41后，所述显示单元34在动画播放区42显示计时提示信息，例如采用圆环以顺时针方向匀速旋转，逐渐形成一闭合圆环的形式，圆环出现到闭合的时间等于所述第一准备时间，如图5所示。圆环转动一圈后即消失，所述图像获取单元35同时进行连拍操作，不到一圈的时间内使用者可松手取消该次连拍操作。
参见图6，在步骤601，等待取景区内屏幕按压输入；在步骤602，判断是否有按下（Pressed Down）事件触发，若有则执行步骤603，否则返回执行步骤601；在步骤603，当取景区内屏幕有按下事件触发，所述图像获取单元35进入触屏拍照状态，所述自动对焦单元37对按下区域进行自动对焦，并等待一预先设定的第一等待时间（例如200ms）；在步骤604，所述第一判断单元32判断在第一等待时间内是否有滑动或抬起（Moved Up）事件触发，若有任意一事件触发（其中，如果有滑动事件触发，则进入屏幕滑动的逻辑），则结束此次连拍操作，返回步骤601继续等待，若两事件均未发生则执行步骤605；在步骤605，所述显示单元34播放动画（例如屏幕上出现从0°（度）顺时针方向开始匀速旋转的部分圆环）；在步骤606，所述第二判断单元33判断在动画播放过程中（例如圆环从0°旋转到360°的一预先设定的第二等待时间内，第二等待时间可以设置为500ms），是否有抬起事件触发，若有任意一事件触发则退出拍照状态，所述图像获取单元35结束此次连拍操作，返回步骤601继续等待，若两事件均未发生则执行步骤607；在步骤607，动画消失，所述图像获取单元35进行连拍操作；在步骤608，判断在拍照过程中是否有抬起事件触发，若有任意一事件触发则退出拍照状态，结束此次连拍操作，返回步骤601继续等待，若两事件均未发生则继续执行步骤607。
根据本发明提供的技术方案，通过点击按压取景框内任何区域的触摸屏屏幕即可启动拍摄程序，通过长按该区域即可实现连拍操作，无需对拍照模式进行设置，简化了连拍操作的设置过程，提供了更快速的连拍操作方式；长按拍照可使取景更稳，更加照顾手型偏小的用户，特别是女性用户，实现单手连拍操作，更同时兼顾方便快捷与稳定，扩大触屏拍照的应用范围；通过准备时间的设置与判断以及显示计时提示信息，使得该次连拍操作是在使用者确认情况下完成的，从而有效避免误操作，提高连拍操作的准确性，有效减少后期删除照片的成本。
