Description

一种拍摄方法及用户终端Shooting method and user terminal

技术领域Technical field

本发明涉及多媒体技术领域，尤其涉及一种拍摄方法及用户终端。The present invention relates to the field of multimedia technologies, and in particular, to a photographing method and a user terminal.

背景技术Background technique

随着电子技术的快速发展，在电子设备上配置摄像头已经成为行业标配，例如，数码相机、摄像机、手机、平板电脑等，这些配置有摄像头的用户终端已经成为人们拍摄用以记录生活点滴的首选。根据成像效果可以将拍摄分为拍照和摄像，拍照的成像效果大部分是静态图像，摄像的成像效果大部分是动态图像。With the rapid development of electronic technology, the configuration of cameras on electronic devices has become a standard in the industry, such as digital cameras, camcorders, mobile phones, tablet computers, etc. These user terminals equipped with cameras have become photographs for people to record life. Preferred. According to the imaging effect, the shooting can be divided into photographing and photographing. The imaging effect of the photographing is mostly static image, and the imaging effect of the camera is mostly a dynamic image.

通常，进行拍照时，当用户确认拍照信息后，例如按下拍摄按钮后，用户终端会将光线会聚到感光器件上，由该感光器件将光信号转变为电信号，得到对应于当前拍照信息的电子图像。再通过模数转换器将得到的电子图像从模拟信号转换到数字信号，并由微处理器对数字信号进行压缩并转化为特定的格式，例如联合图像专家组(Joint Photographic Experts Group，JPEG)格式，完成拍照。Generally, when taking a picture, when the user confirms the photo information, for example, after pressing the shooting button, the user terminal will condense the light onto the photosensitive device, and the photosensitive device converts the optical signal into an electrical signal to obtain a corresponding photo information. Electronic image. The resulting electronic image is converted from an analog signal to a digital signal by an analog-to-digital converter, and the digital signal is compressed by the microprocessor and converted into a specific format, such as the Joint Photographic Experts Group (JPEG) format. , complete the photo.

按照上述流程得到的图像与摄像头所采集的图像相同，若该图像中的背景并不是用户想要的，那么用户可通过一些图像处理软件对该图像中的背景进行处理。目前，对某个图像的背景进行处理的前提条件是该图像已保存，但是用户最终想得到的是处理后的图像，因此，之前保存的图像作用不大，反而会占用一定的存储空间。并且，用户终端根据用户输入的选择指令从多个已保存的图像中确定待处理图像，再根据用户输入的处理指令对待处理图像进行处理，对用户终端而言，较为被动。The image obtained according to the above process is the same as the image captured by the camera. If the background in the image is not what the user wants, the user can process the background in the image through some image processing software. At present, the precondition for processing the background of an image is that the image has been saved, but the user finally wants to obtain the processed image. Therefore, the previously saved image does not have much effect, but it will occupy a certain storage space. Moreover, the user terminal determines the image to be processed from the plurality of saved images according to the selection instruction input by the user, and then processes the image to be processed according to the processing instruction input by the user, which is passive for the user terminal.

For example, when the user terminal starts the camera application, the user terminal extracts a photographed image from the photographed image output by the photographing preview interface. The captured image includes the photographic subject image and the captured background image, acquires a target background image that matches the photographic subject image, and captures the shot The background image is replaced with the target background image, and the subject image and/or the target background image are adjusted, and when an imaging instruction is received, the scene of the adjusted image is output and saved. In the embodiment of the present invention, the background image is replaced during the shooting process, and the background is saved and the background is saved.

Generally, a portion other than the subject in a picture is a photographing background. In the case where the scenery image is not well-determined, the subject can be determined according to the proportion of each part, and the portion with a large proportion can be regarded as a subject, and the other portion is regarded as a shooting background.

下面将结合附图2-附图5对本发明实施例提供的拍摄方法进行详细介绍。The photographing method provided by the embodiment of the present invention will be described in detail below with reference to FIG. 2 to FIG.

请参见图2，是本发明实施例提供的一种拍摄方法的流程示意图，包括但不限于以下步骤：FIG. 2 is a schematic flowchart of a shooting method according to an embodiment of the present invention, including but not limited to the following steps:

步骤S201：在启动相机应用程序的情况下，从拍摄预览界面输出的拍摄图像中提取拍摄对象图像。Step S201: In the case where the camera application is started, the photographic subject image is extracted from the captured image output from the shooting preview interface.

其中，相机应用程序可以是用户终端自带的相机应用程序，即***自带的相机应用程序，也可以是从应用商店下载的相机应用程序，具体是哪种在本发明实施例中不作限定。The camera application may be a camera application that is provided by the user terminal, that is, a camera application that is provided by the system, or a camera application that is downloaded from the application store, which is not limited in the embodiment of the present invention.

用户终端在接收到针对所述相机应用程序输入的启动指令时，启动所述相机应用程序。所述启动指令可以是用户点击或双击所述相机应用程序的图标，也可以是按压所述相机应用程序对应的快捷按钮，还可以是用于启动所述相机应用程序的语音指令等等。The user terminal launches the camera application upon receiving a start command input for the camera application. The startup instruction may be an icon of the camera application clicked or double-clicked by the user, or may be a shortcut button corresponding to pressing the camera application, or may be a voice instruction for starting the camera application or the like.

启动所述相机应用程序，此时所述用户终端的显示界面变为拍摄界面，所述拍摄界面的界面示意图可参见图2所示。请参见图2所示的拍摄界面示意图，其中，白色区域为拍摄预览界面，用于显示摄像头采集的拍摄图像；顶部黑色区域为拍摄选项，包括闪光、定时、色调等选项；底部黑色区域包括拍摄类型选项、图片选项、摄像头选项、拍摄按钮。需要说明的是，图2所示的拍摄界面示意图还包括背景替换选项，未在图2中标明，可能位于顶部黑色区域，也可能位于底部黑色区域，具***置由所述用户终端的制造厂商设定。需要说明的是，图2所示的拍摄界面仅用于举例，所展示的内容以及各个区域所占的比例并不构成对本发明实施例的限定，具体所展示的内容以及各个区域所占的比例由所述用户终端的制造厂商设定。The camera application is started, and the display interface of the user terminal becomes a shooting interface. The interface of the shooting interface can be seen in FIG. 2 . Please refer to the schematic diagram of the shooting interface shown in Figure 2, where the white area is the shooting preview interface for displaying the captured image captured by the camera; the top black area is the shooting option, including flash, timing, color and other options; the bottom black area includes shooting Type options, image options, camera options, shooting buttons. It should be noted that the photographing interface diagram shown in FIG. 2 further includes a background replacement option, which is not indicated in FIG. 2, and may be located in the top black area or in the bottom black area, and the specific position is set by the manufacturer of the user terminal. set. Need to explain The photographing interface shown in FIG. 2 is only used as an example, and the content displayed and the proportion of each area do not constitute a limitation on the embodiment of the present invention, and the content displayed and the proportion of each area are The manufacturer's settings for the user terminal.

在启动所述相机应用程序的情况下，摄像头采集拍摄图像，所述用户终端在所述拍摄预览界面中输出所述拍摄图像。若所述背景替换选项对应于需要进行背景替换，则所述用户终端从输出的所述拍摄图像中提取拍摄对象图像。一般而言，所述拍摄图像由拍摄对象图像和拍摄背景图像组成，以一幅人物图像为例，该人物图像中的人物即为拍摄对象，除人物之外的部分即为拍摄背景。In the case of launching the camera application, the camera captures a captured image, and the user terminal outputs the captured image in the shooting preview interface. If the background replacement option corresponds to the need for background replacement, the user terminal extracts a subject image from the output captured image. Generally, the captured image is composed of a subject image and a photographed background image. Taking a person image as an example, a person in the person image is a subject, and a part other than the person is a photographing background.

在一种可能实现的方式中，所述用户终端根据识物算法从输出的所述拍摄图像中识别出拍摄对象，并提取所述拍摄对象对应的拍摄对象图像。所述识物算法是一种智能的识物算法，能够对拍摄图像中的拍摄对象进行识别，进而便于提取所述拍摄对象对应的拍摄对象图像，例如，采用识物算法识别出是人物，根据人物图像的特征圈定人物的边缘位置，进而提取出人物图像。根据识物算法提取拍摄对象图像，简单便捷，不过提取的准确性依赖于算法的识别度，算法的识别度越高，提取的准确性越高。In a possible implementation manner, the user terminal identifies a photographic subject from the output captured image according to a recognition algorithm, and extracts a photographic subject image corresponding to the photographic subject. The recognition algorithm is an intelligent recognition algorithm capable of recognizing a photographic subject in a captured image, thereby facilitating extraction of a photographic subject image corresponding to the photographic subject, for example, using a recognition algorithm to identify a person, according to The feature of the character image defines the edge position of the character, and the character image is extracted. It is simple and convenient to extract the image of the subject according to the recognition algorithm, but the accuracy of the extraction depends on the recognition degree of the algorithm. The higher the recognition degree of the algorithm, the higher the accuracy of the extraction.

在一种可能实现的方式中，所述用户终端根据针对所述拍摄图像的区域选择指令，从所述拍摄图像中确定出拍摄对象区域，从所述拍摄对象区域中提取拍摄对象图像。所述区域选择指令可以用户输入的，例如，用户在所述拍摄图像中选择圈定一个区域，该区域包括所述拍摄对象图像，但是该区域可能还包括其他图像，因此需进一步从该区域中提取出所述拍摄对象图像。所述区域选择指令也可以是所述用户终端自动识别的，识别出所述拍摄对象图像占用的大概区域，然后再进一步识别出所述拍摄对象图像占用的区域，从而便于提取所述拍摄对象图像。通过在确定拍摄对象区域之后再提取拍摄对象图像，可以缩小提取范围，有利于提高提取的准确性。In a possible implementation manner, the user terminal determines a photographic subject area from the captured image according to an area selection instruction for the captured image, and extracts a photographic subject image from the photographic subject area. The area selection instruction may be input by a user. For example, the user selects and delineates an area in the captured image, the area includes the image of the subject, but the area may further include other images, so further extraction from the area is needed. The subject image is taken out. The area selection instruction may also be automatically recognized by the user terminal, identify an approximate area occupied by the image of the photographic subject, and then further identify an area occupied by the photographic subject image, thereby facilitating extraction of the photographic subject image. . By extracting the image of the subject after determining the region of the subject, the extraction range can be narrowed, which is advantageous for improving the accuracy of the extraction.

上述两种提取拍摄对象图像的方式并不构成对本发明实施例的限定，还可以采用其他方式提取拍摄对象图像。The above two methods of extracting the image of the subject are not limited to the embodiment of the present invention, and the image of the subject may be extracted by other means.

步骤S202：获取与所述拍摄对象图像相匹配的目标背景图像，并将所述拍摄背景图像替换为所述目标背景图像。Step S202: Acquire a target background image that matches the image of the photographic subject, and replace the captured background image with the target background image.

所述用户终端获取与所述拍摄对象图像相匹配的目标背景图像，并将所述拍摄背景图像替换为所述目标背景图像。所述目标背景图像可以是静态的，也可以是动态的。所述目标背景图像可以是留有空白的背景图像，这些空白的地方可用于所述拍摄对象图像的填充，以便与所述拍摄对象图像融合。所述目标背景图像也可以是未留有空白的背景图像，与所述拍摄对象图像融合时，所述拍摄对象图像可置于所述目标背景图像之上，即所述拍摄对象图像将重叠部分覆盖了，对用户而言，看不到所述目标背景图像中的这部分。The user terminal acquires a target background image that matches the image of the photographic subject, and replaces the captured background image with the target background image. The target background image can be static, also Can be dynamic. The target background image may be a background image with blanks, and the blanks may be used for filling of the photographic subject image to be fused with the photographic subject image. The target background image may also be a background image without leaving a blank. When fused with the photographic subject image, the photographic subject image may be placed above the target background image, that is, the photographic subject image will overlap. Covered, for the user, this part of the target background image is not visible.

在一种可能实现的方式中，所述用户终端可直接向所述相机应用程序对应的服务器获取所述目标背景图像。所述用户终端可将提取的所述拍摄对象图像发送至所述服务器，由所述服务器在数据库存储的多个背景图像中选择一个作为目标背景图像，并将选择的所述目标背景图像发送至所述用户终端。所述服务器可通过一些算法在多个背景图像中选择一个作为目标背景图像。所述服务器还可以通过数据库中的匹配记录确定目标背景图像。In a possible implementation manner, the user terminal may directly acquire the target background image from a server corresponding to the camera application. The user terminal may send the extracted image of the photographic subject to the server, select one of the plurality of background images stored in the database as the target background image, and send the selected target background image to the target terminal image The user terminal. The server may select one of the plurality of background images as the target background image by some algorithms. The server can also determine the target background image from the matching records in the database.

在一种可能实现的方式中，所述用户终端可从所述相机应用程序对应的服务器中获取与所述拍摄对象图像相匹配的背景图像集合，根据针对所述背景图像集合输入的选择指令从背景图像集合中确定目标背景图像。例如，所述拍摄对象图像为人物图像，与人物图像相匹配的背景图像集合可以是风景背景图像集合，即所述服务器为人物图像提供多个风景背景图像，用户可从这多个风景背景图像中选择一个作为目标背景图像。In a possible implementation manner, the user terminal may acquire, from a server corresponding to the camera application, a background image set that matches the image of the photographic subject, according to a selection instruction input for the background image set. The target background image is determined in the background image collection. For example, the image of the subject is a person image, and the set of background images matching the image of the person may be a set of landscape background images, that is, the server provides a plurality of landscape background images for the character image, and the user may obtain images from the plurality of landscape backgrounds. Select one as the target background image.

在一种可能实现的方式中，所述用户终端可提供本端存储的一些图像并将这些图像作为背景图像供用户选择，然后根据用户针对这些图像输入的选择指令确定目标背景图像。In a possible implementation manner, the user terminal may provide some images stored by the local end and use the images as background images for the user to select, and then determine a target background image according to a selection instruction input by the user for the image inputs.

在一种可能实现的方式中，所述用户终端可对所述拍摄背景图像进行旋转得到一个背景图像，将这个背景图像作为目标背景图像。旋转的角度在本发明实施例中不作限定。In a possible implementation manner, the user terminal may rotate the shooting background image to obtain a background image, and use the background image as a target background image. The angle of rotation is not limited in the embodiment of the invention.

上述几种获取目标背景图像的方式并不构成对本发明实施例的限定，还可以采用其他方式获取目标背景图像。The manner of obtaining the target background image does not limit the embodiment of the present invention, and the target background image may be acquired in other manners.

请参见图4，是本发明实施例提供的背景替换示意图。图4中的背景替换过程为：白色的拍摄背景图像替换为灰色的目标背景图像，而拍摄对象图像未发生变化，并且此时用户还未输入拍摄指令。需要说明的是，图4所示仅用于举例，并不构成对本发明实施例的限定。FIG. 4 is a schematic diagram of a background replacement provided by an embodiment of the present invention. The background replacement process in FIG. 4 is that the white shooting background image is replaced with the gray target background image, and the subject image has not changed, and the user has not input the shooting instruction at this time. It should be noted that FIG. 4 is only for exemplification and does not constitute a limitation on the embodiments of the present invention.

步骤S203：调整所述拍摄对象图像和/或所述目标背景图像。 Step S203: Adjust the subject image and/or the target background image.

所述用户终端调整所述拍摄对象图像和/或所述目标背景图像，以更好地融合所述拍摄对象图像和所述目标背景图像，使融合后的图像效果更好。The user terminal adjusts the photographic subject image and/or the target background image to better fuse the photographic subject image and the target background image, so that the fused image effect is better.

在一种可能实现的方式中，用户移动和/或偏转所述用户终端，使得所述拍摄对象图像对应的原始拍摄对象与所述用户终端的摄像头之间距离和/或角度发生变化，进而影响在所述拍摄预览界面输出的所述拍摄对象图像。用户通过移动和/或偏转所述用户终端来调整所述拍摄对象图像，以便所述拍摄对象图像与所述目标背景图像更好地融合。具体根据所述拍摄对象图像对应的原始拍摄对象与所述摄像头之间的距离和/或角度调整所述拍摄对象图像的方法在本发明实施中不作限定。In a possible implementation manner, the user moves and/or deflects the user terminal such that the distance and/or angle between the original photographic subject corresponding to the photographic subject image and the camera of the user terminal changes, thereby affecting The subject image outputted on the photographing preview interface. The user adjusts the subject image by moving and/or deflecting the user terminal such that the subject image blends better with the target background image. The method for adjusting the image of the photographic subject according to the distance and/or the angle between the original photographic subject and the camera corresponding to the photographic subject image is not limited in the implementation of the present invention.

在一种可能实现的方式中，用户移动所述用户终端，不改变所述拍摄对象图像，而是改变所述目标背景图像，根据所述拍摄对象图像对应的原始拍摄对象与所述摄像头之间的距离调整所述目标背景图像的方法在本发明实施中不作限定。In a possible implementation manner, the user moves the user terminal without changing the image of the photographic subject, but changes the target background image, according to the original photographic object corresponding to the photographic subject image and the camera The method of adjusting the target background image is not limited in the implementation of the present invention.

在一种可能实现的方式中，所述用户终端根据用户输入的调整指令调整所述拍摄对象图像或所述目标背景图像。所述调整指令可以是针对所述拍摄对象图像输入的，此时根据所述调整指令调整所述拍摄对象图像；也可以是针对所述目标背景图像输入的，此时根据所述调整指令调整所述目标背景图像。In a possible implementation manner, the user terminal adjusts the photographic subject image or the target background image according to an adjustment instruction input by a user. The adjustment instruction may be input to the image of the photographic subject, and the image of the photographic subject is adjusted according to the adjustment instruction; or may be input for the target background image, and the adjustment instruction is adjusted according to the adjustment instruction. The target background image.

上述几种调整方式并不构成对本发明实施例的限定，还可以采用其他方式进行调整。The above adjustment manners do not constitute a limitation on the embodiments of the present invention, and may be adjusted in other manners.

步骤S204：在接收到拍摄指令的情况下，输出并保存调整后的图像。Step S204: When the shooting instruction is received, the adjusted image is output and saved.

所述用户终端在接收到拍摄指令的情况下，输出并保存调整后的图像。The user terminal outputs and saves the adjusted image when receiving the shooting instruction.

用户调整所述拍摄对象图像和/或所述目标背景图像以寻找所需的合成效果，在用户确定所需的合成效果时，针对所述拍摄预览界面中的拍摄按钮输入的拍摄指令或针对物理拍摄按键输入的拍摄指令，即点击或按压所述拍摄按钮或物理拍摄按键。所述用户终端在接收所述拍摄指令时，将调整后的图像输出并保存所述调整后的图像，即输出并保存合成图像。这样，用户终端只需保存最终合成的图像，而无需保存待处理的图像，可以节省存储空间。The user adjusts the photographic subject image and/or the target background image to find a desired compositing effect, and when the user determines a desired compositing effect, a shooting instruction or a physics input for the shooting button in the shooting preview interface Shoot the shooting command input by the button, that is, click or press the shooting button or physical shooting button.
