Description

图像获取方法、图像获取装置和终端
本申请要求于2015年3月11日提交中国专利局、申请号为201510105442.7，发明名称为“图像获取方法、图像获取装置和终端”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
本发明涉及终端技术领域，具体而言，涉及一种图像获取方法和一种图像获取装置和一种终端。
背景技术
目前，由于终端(如手机、平板电脑等)上安装有单摄像头，越来越多的用户通过终端上的单摄像头进行拍照，但是单个摄像头在调节焦距时，只能调节一个范围的焦距，以至于拍摄的照片只能在一定距离内是清晰的，拍摄较远的距离的照片是模糊的。
因此，如何使终端具有调节多个范围的对焦距离的功能，从而提高拍摄较远距离的照片的清晰度，成为亟待解决的问题。
发明内容
本发明正是基于上述问题，提出了一种新的技术方案，通过在终端上设置多个摄像头，使终端具有调节多个范围的对焦距离的功能，从而增大拍摄到的图像的景深，提高拍摄图像的清晰度，并使终端可以拍摄到更远更清晰的图像。
有鉴于此，本发明的一方面提出了一种图像获取方法，包括：根据接收到的第一设置命令，设置多个摄像头中的每个摄像头的对焦距离；获取所述每个摄像头拍摄到的关于目标对象的拍摄数据；根据接收到的第二设置命令，分别为所述每个摄像头所拍摄的拍摄数据设置标记，以根据所述每个摄像头所拍摄的拍摄数据中的标记和所述每个摄像头所拍摄的拍摄数据获取所述目标对象的目标图像。
在该技术方案中，由于多个摄像头中的每个摄像头与目标对象的远近程度不同，因此，设置多个摄像头中的每个摄像头的对焦距离，使终端具有调节多 个范围的对焦距离的功能，从而增大拍摄到的图像景深，提高拍摄图像的清晰度，不仅使每个摄像头拍摄到的关于目标对象的拍摄数据更加准确，还可以获取更远更清晰的图像，又由于每个摄像头所对应的感光处理器或图像处理器会有不同时间的延时，因此，为每个摄像头所拍摄的拍摄数据设置标记，从而使目标对象的目标图像更加清晰，例如，在设置多个摄像头中的每个摄像头的对焦距离时，根据多个摄像头和目标对象之间的距离，多次调节每个摄像头的对焦距离，从而保证每个摄像头拍摄到的拍摄图像更加清晰，另外，为每个摄像头所拍摄的拍摄数据设置标记时，可以通过数字对拍摄数据设置标记。
在上述技术方案中，优选地，所述设置多个摄像头中的每个摄像头的对焦距离，具体包括：根据所述多个摄像头中的每个摄像头与所述目标对象的距离，为所述多个摄像头中的任一摄像头设置第一对焦距离；根据所述第一对焦距离分别为每个其他摄像头设置第二对焦距离，其中，所述每个其他摄像头为所述多个摄像头中除所述任一摄像头之外的摄像头。
在该技术方案中，为任一摄像头设置第一对焦距离，并根据第一对焦距离分别为每个其他摄像头设置第二对焦距离，从而使每个摄像头拍摄到的关于目标对象的拍摄数据更加准确，进而可以增大拍摄到的图像的景深，使获取到的目标图像更加清晰，例如，设置多个摄像头中的任一摄像头的第一对焦距离为10厘米，则设置每个其他摄像头设置第二对焦距离为15厘米。
在上述技术方案中，优选地，还包括：根据接收到的控制命令，控制所述每个摄像头的焦点在同一直线上。
在该技术方案中，控制每个摄像头的焦点在同一条直线上，这样才能保证每个摄像头拍摄到的关于目标对象的拍摄数据是相同的，也就是说每个摄像头所获取的关于目标对象的画面是相同的，从而保证获取到的带拍摄对象的拍摄数据更加准确，进而使合成后的目标图像更加清晰。

在该技术方案中，在每个摄像头拍摄关于目标对象的拍摄数据时，由于每个摄像头所对应的感光处理器或图像处理器会有不同时间的延时，所以每个摄像头所拍摄的拍摄数据的时间可能是不同的，如果直接根据每个摄像头拍摄到的拍摄数据合成目标图像，这样会使目标图像出现画面不一致，因此，将每个摄像头在同一时间所获取的每一帧的目标拍摄数据中的每个像素点的像素值进行加权，其中，目标拍摄数据具有相同的标号，从而得到景深较大的目标图像，进而使得目标图像更加清晰，另外，在按照时间顺序为每个摄像头在不同时间所拍摄的拍摄数据设置不同标号时，时间间隔可以是由用户设置，也可以是系统默认，且时间的起点可以为每个摄像头在进行拍摄时的时间。

在该技术方案中，为任一摄像头设置第一对焦距离，并根据第一对焦距离分别为每个其他摄像头设置第二对焦距离，从而使每个摄像头拍摄到的关于目标对象的拍摄数据更加准确，进而可以增大拍摄到的图像的景深，使获取到的目标图像更加清晰，例如，设置多个摄像头中的任一摄像头的第一对焦距离为10厘米，则设置每个其他摄像头设置第二对焦距离为15厘米。
在上述技术方案中，优选地，还包括：控制单元，根据接收到的控制命令，控制所述每个摄像头的焦点在同一直线上。

在该技术方案中，由于终端每次获取目标对象的目标图像时，每个摄像头与目标对象的距离是不同的，所以重新调整每个摄像头的对焦距离，使每个摄像头拍摄到的关于目标对象的拍摄数据更加准确，从而使每一次获取到的目标对象的目标图像都很清晰。
图2示出了根据本发明的一个实施例的图像获取装置的结构示意图。
如图2所示，根据本发明的一个实施例的图像获取装置200，包括：第一设置单元202、获取单元204和第二设置单元206，其中，所述第一设置单元202用于根据接收到的第一设置命令，设置多个摄像头中的每个摄像头的对焦距离；获取单元204，获取所述每个摄像头拍摄到的关于目标对象的拍摄数据；第二设置单元206，根据接收到的第二设置命令，分别为所述每个摄像头所拍摄的拍摄数据设置标记，以根据所述每个摄像头所拍摄的拍摄数据中的标记和所述每个摄像头所拍摄的拍摄数据获取所述目标对象的目标图像。
在该技术方案中，由于多个摄像头中的每个摄像头与目标对象的远近程度不同，因此，设置多个摄像头中的每个摄像头的对焦距离，使终端具有调节多个范围的对焦距离的功能，从而增大拍摄到的图像景深，提高拍摄图像的清晰度，不仅使每个摄像头拍摄到的关于目标对象的拍摄数据更加准确，还可以获取更远更清晰的图像，又由于每个摄像头所对应的感光处理器或图像处理器会有不同时间的延时，因此，为每个摄像头所拍摄的拍摄数据设置标记，从而使目标对象的目标图像更加清晰，例如，在设置多个摄像头中的每个摄像头的对焦距离时，根据多个摄像头和目标对象之间的距离，多次调节每个摄像头的对焦距离，从而保证每个摄像头拍摄到的拍摄图像更加清晰，另外，为每个摄像头所拍摄的拍摄数据设置标记时，可以通过数字对拍摄数据设置标记。
在上述技术方案中，优选地，所述第一设置单元202具体用于：根据所述多个摄像头中的每个摄像头与所述目标对象的距离，为所述多个摄像头中的任一摄像头设置第一对焦距离；根据所述第一对焦距离分别为每个其他摄像头设置第二对焦距离，其中，所述每个其他摄像头为所述多个摄像头中除所述任一摄像头之外的摄像头。
在该技术方案中，为任一摄像头设置第一对焦距离，并根据第一对焦距离分别为每个其他摄像头设置第二对焦距离，从而使每个摄像头拍摄到的关于目标对象的拍摄数据更加准确，进而可以增大拍摄到的图像的景深，使获取到的目标图像更加清晰，例如，设置多个摄像头中的任一摄像头的第一对焦距离为10厘米，则设置每个其他摄像头设置第二对焦距离为15厘米。
在上述技术方案中，优选地，还包括：控制单元208，根据接收到的控制命令，控制所述每个摄像头的焦点在同一直线上。
在该技术方案中，控制每个摄像头的焦点在同一条直线上，这样才能保证每个摄像头拍摄到的关于目标对象的拍摄数据是相同的，也就是说每个摄像头所获取的关于目标对象的画面是相同的，从而保证获取到的带拍摄对象的拍摄数据更加准确，进而使合成后的目标图像更加清晰。
在上述技术方案中，优选地，第二设置单元206具体用于：根据接收到的第二设置命令，按照时间顺序为所述每个摄像头在不同时间所拍摄的拍摄数据设置不同标号，并确保所述多个摄像头在同一时间所拍摄的目标拍摄数据具有相同标号；将所述多个摄像头所获取的所述相同标号的目标拍摄数据进行合成，以获取所述目标图像。

图3示出了根据本发明的另一个实施例的图像获取装置的原理示意图。
如图3所示，根据本发明的另一个实施例的图像获取装置300的原理(在该实施例中，终端为手机，手机上安装有双摄像头，即摄像头A和摄像头B)，包括：
1.主控ISP(Image Signal Processor，图像处理器)控制摄像头A对焦点A进行对焦，同时还控制摄像头B对焦点B进行对焦。
2.获取摄像头A和摄像头B拍摄到的关于目标对象的帧数据(拍摄数据)。
3.为摄像头A和摄像头B所拍摄的帧数据进行标记(为每个摄像头所拍摄的拍摄数据设置标记)。
4.主控ISP获取相同的标记的帧数据，并将具有相同的标记的帧数据进行合成(依次将多个摄像头所对应的相同标号的目标拍摄数据进行合成)，从而获取目标图像。
图4示出了根据本发明的一个实施例的标记拍摄数据的原理结构示意图。
如图4所示，根据本发明的一个实施例的标记拍摄数据，在每个摄像头拍摄关于目标对象的帧数据(拍摄数据)时，由于每个摄像头所对应的感光处理器或图像处理器会有不同时间的延时，所以每个摄像头所拍摄的帧数据的时间可能是不同的，如果直接根据每个摄像头拍摄到的帧数据合成目标图像，这样会使目标图像出现画面不一致。
因此，可以按照时间顺序依次为每个摄像头在不同时间所拍摄的帧数据设置不同标号，且同一时间所拍摄的目标帧数据具有相同标号，然后依次将多个摄像头所对应的相同标号的目标拍摄数据进行合成，从而使每个摄像头拍摄到 的关于目标对象的帧数据可以同步，则获取到的目标对象的目标图像更加准确，从而使目标图像更加清晰。
例如，对摄像头A的帧数据进行标记，第一帧数据ID：A_id1，第二帧数据ID：A_id2，第三帧数据ID：A_id3等，摄像头A的其他帧数据的标记以此类推；对摄像头B的帧数据进行标记，第一帧数据ID：A_id1，第二帧数据ID：A_id2，第三帧数据ID：A_id3等，摄像头B的其他帧数据的标记以此类推，其中，摄像头的驱动层完成帧数据的ID标记。主ISP在合成目标图像时，提取缓存中具有相同ID号的帧数据，从而达到不同摄像头的帧数据的同步，使合成的目标图像更加准确与清晰。比如，提取摄像头A的第二帧数据A_id2，检测摄像头B缓存中的帧数据ID，直到获取B_id2的帧数据，才执行帧数据的合成。

在上述技术方案中，优选地，所述处理器501还用于执行如下步骤：
根据接收到的调整命令，调整多个摄像头中的每个摄像头的对焦距离。
在该技术方案中，由于多个摄像头中的每个摄像头与目标对象的远近程度不同，设置每个摄像头中的每个摄像头的对焦距离，使终端具有调节多个范围的对焦距离的功能，不仅使每个摄像头拍摄到的关于目标对象的拍摄数据更加准确，还可以获取更远更清晰的图像，又由于每个摄像头所对应的感光处理器或图像处理器会有不同时间的延时，即每个摄像头所拍摄的拍摄数据的时间可能是不同的，因此，在获取每个摄像头拍摄到的关于目标对象的拍摄数据之后，按照时间顺序为每个摄像头所拍摄的拍摄数据设置多个标记，将具有相同标记的拍摄数据进行合成，从而使合成的目标图像中每个摄像头的拍摄数据是同步的，避免目标图像出现模糊，使目标图像更加清晰。
