Description

图像处理方法、图像处理装置和终端
本申请要求于2015年7月15日提交中国专利局、申请号为201510417390.7，发明名称为“图像处理方法、图像处理装置和终端”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，涉及一种图像处理方法、一种图像处理装置和一种终端。
背景技术
目前，终端在进行拍照时，若是在弱光环境下则拍照出的照片的噪点比较大，导致在弱光环境下拍摄得到的照片的质量较差。在相关技术中，通常用户手动开启场景模式来自动检测终端是否为处于弱光环境，若终端处于弱光环境，则启动弱光模式，另一种方案是，用户手动切换至特效模式下的弱光模式进行拍照。
但是，开启弱光模式均需要用户手动来开启，并且由于在弱光模式下需要长时间的曝光和处理，导致拍照时需要花费很长时间，而且在弱光环境下拍照得到的照片的噪点比较大，以及在预览待拍摄图像时也会导致图像拖影严重，导致用户不好的使用体验。
因此，如何在弱光环境下时减少拍摄得到的图片的噪点，同时避免在预览待拍摄图像时出现拖影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，在弱光环境下对待拍摄图像进行拍照时，不仅可以有效地减少拍摄得到的图片的噪点，还避免了在预览待拍摄图像时出现拖影，从而提升用户体验。
有鉴于此，本发明的第一方面提出了一种图像处理方法，用于终端，所述终端上设置有多个摄像头，所述图像处理方法包括：控制所述多个摄像头中的任一摄像头预览待拍摄图像；当判定所述终端处于弱光环境下时， 在其他摄像头的第一数据通道中以第一帧率生成所述待拍摄图像的数据；根据所述第一数据通道中的所述待拍摄图像的第一目标数据确定所述待拍摄图像，其中，所述第一帧率小于第一阈值，所述其他摄像头为所述多个摄像头中的除所述任一摄像头之外的摄像头。
在该技术方案中，当终端处于弱光环境下拍照时，控制终端的多个摄像头中的任一摄像头预览待拍摄图像，由于任一摄像头处于正常的拍照模式下，避免了在预览待拍摄图像时出现拖影。而且在对待拍摄图像进行拍照时，在其他摄像头的第一数据通道中以第一帧率生成待拍摄图像的数据，由于第一帧率为低帧率，例如，第一帧率为24帧每秒，使得在第一数据通道中的待拍摄图像的数据为经过足够的时间曝光的数据，这样对第一数据通道中的待拍摄图像的第一目标数据(即第一数据通道中的待拍摄图像的某一帧的数据)解码以及编码得到的待拍摄图像的质量就比较高，不仅避免了在拍照得到的待拍摄图像中出现较大的噪点，还减少了拍照的时间，从而提升了用户体验。
在上述技术方案中，优选地，当判定所述终端处于非弱光环境下时，在所述任一摄像头的第二数据通道中以第二帧率生成所述待拍摄图像的数据，其中，所述第二帧率大于第二阈值；对所述第二数据通道中的所述待拍摄图像的第二目标数据进行编码以及解码以得到所述待拍摄图像。
在该技术方案中，若终端不是在弱光环境下，即终端所在的环境的光线比较强，即使任一摄像头处于正常的拍照模式下，在任一摄像头的第二数据通道中的数据为经过充分曝光的数据，且在任一摄像头的第二数据通道中以第二帧率生成待拍摄图像的数据，由于第二帧率为高帧率，例如，第二帧率为48帧每秒，从而在第二数据通道中获取到的待拍摄图像的第二目标数据得到的待拍摄图像的质量也比较高。
在上述技术方案中，优选地，在所述控制所述多个摄像头中的任一摄像头预览待拍摄图像的步骤之后，包括：获取所述终端所在的当前环境的环境亮度；若所述环境亮度小于或等于预设亮度时，判定所述终端处于所述弱光环境下，若所述环境亮度大于预设亮度时，判定所述终端处于所述非弱光环境下。
