技术领域Technical field
本发明涉及图像处理领域，特别涉及一种拍摄方法、拍摄装置和存储介质。The present invention relates to the field of image processing, and in particular, to a photographing method, a photographing apparatus, and a storage medium.
背景技术Background technique
随着信息技术的不断发展，移动终端(如手机、相机等)的图像处理功能也越来越强大，利用移动终端进行拍照可谓是无所不在。然而，在拍照过程中，对有不同景深的场景，每个目标与镜头的距离通常不等，只能选择对某一景深目标进行对焦采集，这样就会使得其它区域相对模糊。With the continuous development of information technology, the image processing functions of mobile terminals (such as mobile phones, cameras, etc.) are becoming more and more powerful, and taking pictures using mobile terminals can be described as ubiquitous.

在本发明一些实施例中，所述拍摄方法可以在所述拍摄装置处于预设的拍摄状态时获取所述拍摄装置当前采集的预览图片。具体地，所述拍摄方法可以先判断所述拍摄装置当前是否处于预设的拍摄状态，若所述拍摄装置当前处于所述预设的拍摄状态，所述拍摄方法获取所述拍摄装置当前采集的预览图片。In some embodiments of the present invention, the photographing method may acquire a preview picture currently acquired by the photographing apparatus when the photographing apparatus is in a preset photographing state. Specifically, the photographing method may first determine whether the photographing device is currently in a preset photographing state, and if the photographing device is currently in the preset photographing state, the photographing method acquires a current photographing device currently acquired by the photographing device. preview picture.
所述预设的拍摄状态可以是所述拍摄装置处于开启状态，也可以是所述拍摄装置处于开启状态且所述拍摄装置的传感器感测到的数据变化小于第一预设阈值，还可以是用户在所述拍摄装置上执行拍摄操作。The preset shooting state may be that the shooting device is in an on state, or the camera device is in an on state and the data sensed by the sensor of the camera device is less than a first preset threshold, or may be The user performs a photographing operation on the photographing device.
对应地，所述拍摄方法判断所述拍摄装置当前是否处于预设的拍摄状态可以通过侦测拍摄装置当前是否处于开启状态，若所述拍摄装置当前处于开启状态，所述拍摄方法确定所述拍摄装置当前处于所述预设的拍摄状 态。Correspondingly, the photographing method determines whether the photographing device is currently in a preset shooting state by detecting whether the photographing device is currently in an open state, and if the photographing device is currently in an open state, the photographing method determines the photographing The device is currently in the preset shooting state state.
在本发明一些实施例中，所述拍摄方法还可以在侦测到所述拍摄装置当前处于开启状态后，所述拍摄方法进一步判断所述拍摄装置的传感器感测的数据变化小于第一阈值，若所述拍摄装置的传感器感测的数据变化小于所述第一阈值，所述拍摄方法确定所述拍摄装置当前处于所述预设的拍摄状态。具体地，所述传感器可以为加速度传感器，例如陀螺仪，若所述加速度传感器当前感测的数据相较于前一时刻感测的数据的差值小于所述第一阈值，则说明用户可能正准备所述拍摄装置进行拍摄，所述拍摄方法确定所述拍摄装置当前处于预设的拍摄状态。此外，所述拍摄方法还可以通过判断所述拍摄装置采集的预览图片的亮度变化值是否小于第二阈值，若所述预览图片的亮度变化值小于所述第二阈值，所述拍摄方法确定所述拍摄装置当前处于预设的拍摄状态。在其他实施例中，所述拍摄方法可以通过上述两个方式结合判断所述拍摄装置是否处于预设的拍摄状态，例如若所述拍摄装置的传感器感测的数据变化值小于第一阈值且所述拍摄装置采集的预览图片的亮度变化值小于第二阈值，所述拍摄方法确定所述拍摄装置处于所述预设的拍摄状态。In some embodiments of the present invention, the photographing method may further determine that the sensor-sensed data change of the photographing device is less than a first threshold after detecting that the photographing device is currently in an open state. If the data sensed by the sensor of the photographing device is less than the first threshold, the photographing method determines that the photographing device is currently in the preset photographing state. Specifically, the sensor may be an acceleration sensor, such as a gyroscope. If the difference between the data currently sensed by the acceleration sensor and the data sensed at a previous time is less than the first threshold, the user may be positive. The photographing device is prepared for photographing, and the photographing method determines that the photographing device is currently in a preset photographing state. In addition, the photographing method may further determine whether the brightness change value of the preview picture collected by the photographing device is less than a second threshold, and if the brightness change value of the preview picture is smaller than the second threshold, the photographing method determines The photographing device is currently in a preset shooting state. In other embodiments, the photographing method may be combined to determine whether the photographing device is in a preset photographing state by using the above two methods, for example, if the sensor-sensed data change value of the photographing device is less than a first threshold value. The brightness change value of the preview picture collected by the photographing device is less than a second threshold, and the photographing method determines that the photographing device is in the preset photographing state.

If the adjacent area in the preview picture satisfies the preset condition, the photographing method may combine the adjacent areas into one area for processing. For example, the photographing method may focus on the adjacent area to take a picture and focus on other areas and take a picture, and then extract a focused area picture in the captured picture, and focus on the focus. The area image is a composite target image.
需要说明的是，在本发明的实施例中，所述拍摄的图片并不一定会全部呈现给用户，例如，在所述步骤S103中，所述对每个区域进行对焦拍摄的图片不会呈现给用户，只有最后合成的目标图片会呈现给用户。It should be noted that, in the embodiment of the present invention, the captured pictures are not necessarily all presented to the user.
