具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本 公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
下面对本公开实施例的应用场景进行解释：
图1为本公开实施例提供的图像预览方法的一种应用场景图，本公开实施例提供的图像预览方法，可以应用于基于终端设备向内容创作类应用上传媒体数据的场景中，更具体地，可以应用于加载输出媒体数据的应用场景下，输出媒体数据即用于后续编辑、上传至内容创作类应用的媒体数据。如图1所示，本公开实施例提供的方法，可以应用于终端设备，例如智能手机。示例性地，内容创作类应用是指用户能够上传自制的图像、视频、文字等媒体数据的应用平台，更具体地，例如短视频应用、视频网站应用等，同时，其他具有用户上传媒体数据功能的应用，也属于内容创作类应用的范畴，例如可以允许个人用户上传媒体数据的社交类应用、新闻类应用等。内容创作类应用包括服务端和客户端，其中，客户端运行在终端设备一侧，用户通过操作终端设备，利用客户端加载输出媒体数据，之后将该输出媒体数据进行编辑、上传至服务端，完成用户创造内容的上传。其他终端设备通过运行该内容创作类应用的客户端，可以看到该输出媒体数据，例如用户自制视频、图片等。
现有技术中，在内容创作类应用的客户端内，提供有上传自制内容对应的媒体数据的触发控件，用户在点击该触发控件，客户端会显示对应的上传流程页面，来引导用户进行媒体数据的上传。图2为现有技术中的一种上传媒体数据的流程示意图，如图2所示，示例性地，在用户点击客户端内的“上传我的作品”触发控件后，在新弹出的页面内，显示“拍摄视频/照片”和“加载视频/照片”两个控件来引导用户的后续操作，当用户点击“拍摄视频/照片”后，客户端启动相机取景框页面，进行拍摄取景，并基于用户的拍摄操作，进行视频或照片的拍摄，生成输出媒体数据；当用户点击“加载视频/照片”后，客户端启动媒体数据库页面，展示终端设备内的本地媒体数据库或云端媒体数据库内存储的视频和/或照片，并基于用户的点选操作，获得输出媒体数据。
然而，在实际应用过程中，在用户进行内容创造的应用场景下，用户进行内容创造的过程主观、复杂，一方面，在用户通过相机取景框页面，进行拍摄取景的过程中，用户需要观察在取景框中呈现的图像的视觉效果是否满足需要、光线是否充足、是否存在遮挡物等，再决定是否进行拍摄；另一方面，由于媒体数据库内存储的媒体数据不止一组，需要用户对媒体数据库内的内容进行观察后，才能够进行选取并加载。也即，用户需要基于具体的观察结果，来决定开启相机取景框页面，以“实时拍摄”的方式获得媒体数据，还是开启媒体数据库页面，以“加载现有媒体数据”的方式获得媒体数据。而现有技术中的方案，只能择一开启相机取景框页面或媒体数据库页面，而无法同时实现对相机取景效果和媒体数据库内容的同时预览，因此只能反复切换开启相机取景框页面和媒体数据库页面，来分别对相机取景效果和媒体数据库内容进行预览，造成了获取输出媒体数据的耗时增加，影响用户的创作效率的问题。本公开实施例提供一种图像预览方法以解决上述问题。
参考图3，图3为本公开实施例提供的图像预览方法的流程示意图一。本实施例的方法可以应用在终端设备中，该图像预览方法包括：
步骤S101：响应于相机启动指令，启动相机取景框页面，相机取景框页面内包括第一界面组件。
示例性地，本实施例方法的执行主体为终端设备，更具体地，例如为智能手机，终端设备内运行有内容创作类应用的客户端(以下简称客户端)，在客户端中，设置有用于触发相机启动指令的相机控件，当用户通过操作终端设备，触发该相机控件后，生成对应的相机启动指令，之后，响应于该相机启动指令，在客户端内启动相机取景框页面。图4为本公开实施例提供的一种相机取景框页面的示意图，如图4所示，示例性地，在相机取景框页面内，包括位于相机取景框页面中部的相机取景框，以及位于相机取景框下部的拍摄触发控件，该拍摄触发控件用于控制终端设备拍摄视频或图片，上述相机取景框页面中的相机取景框和拍摄触发控件为现有技术中相机取景框页面内的常用功能单元，实现原理不再赘述。
进一步地，在相机取景框页面的第一目标位置，例如图4中拍摄触发控件右侧，还设置有第一界面组件，所述第一界面组件提供媒体数据库的交互入口，该第一界面组件用于以预览图像的形式，展示媒体数据库页面中的媒体数据。其中，除如图4中所示位置外，第一界面组件还可以设置于其他目标位置，此处不作限制，具体可根据需要设置。进一步地，第一界面组件可以为一个或多个组件，当第一界面组件为多个组件时，多个组件之间可设置在相邻位置，便于用户观察，具体位置不作限制，也不再赘述。
步骤S102：基于第一界面组件，在第一时间段内，展示至少两帧预览图像，预览图像是基于媒体数据库内的媒体数据生成的。
示例性地，在启动相机取景框页面，通过第一界面组件动态展示预览图像，其中，在第一界面组件动态展示预览图像，即在第一时间段内，以切换显示的方式，展示至少两帧预览图像。该预览图像是基于媒体数据库内的媒体数据生成的，例如，确定媒体数据库内的目标媒体数据后，对媒体数据库内的目标媒体数据进行采样后，将生成的缩略图作为预览图像。其中，目标媒体数据可以是随机确定的，也可以是基于某种规则确定的。
进一步地，媒体数据包括视频和图片，当媒体数据为视频时，可以从视频中选取出至少两个视频帧，例如两个相邻的关键帧，进行处理后作为对应的预览图像在第一界面组件内展示。图5为本公开实施例提供的一种在第一界面组件内动态展示预览图像的示意图，如图5所示，在启动相机取景框页面，终端设备在获取用户授权的情况下，读取媒体数据库内的媒体数据，其中，该媒体数据库可以是本地媒体数据库，也可以是云端媒体数据库。并从中选取出至少两个目标媒体数据，例如为三张照片(图中示为照片A、照片B和照片C)；之后在第一时间段内，例如2秒内，将该三张照片分别切换显示在第一界面组件内，即第0秒时显示照片A、第1秒时显示照片B、第2秒时显示照片C。从而使用户在观察相机取景框页面的同时，可以在3秒钟内，观察到媒体数据库内三张照片的预览图像。其中，示例性地，该第一时间段由预览图像的数量确定，或者，预览图像的数量由预设的第一时间段确定。
之后，可选地，用户可以基于观察到的第一页面组件内的预览图像，决定使用预览图像对应的媒体数据库页面内的媒体数据作为输出媒体数据进行加载，还是直接通过相机取景框进行实时拍摄，直接生成输出媒体数据进行加载。从而实现方便、快捷的加载输出媒体数据，执行后续编辑、上传该输出媒体数据的步骤。
本实施例中，通过响应于相机启动指令，启动相机取景框页面，相机取景框页面内包括第一界面组件；基于第一界面组件，在第一时间段内，展示至少两帧预览图像，预览图 像是基于媒体数据库内的媒体数据生成的。由于在相机取景框页面内设置了可以动态展示预览图像的第一界面组件，使相机取景框页面能够在实现相机取景的同时，动态展示媒体数据库中的内容，从而使用户通过观察相机取景框页面，即可同时预览到实时拍摄媒体数据的结果和加载已有媒体数据的结果，进而帮助用户快速做出决策，而无需分别打开相机取景框页面和媒体数据库页面，分别进行尝试和查找，简化操作步骤，提高交互效率，提高最终用于上传至内容创作类应用的输出媒体数据的生成速度。
在图3所示实施例的基础上，进一步地，在一种可能的实现方式中，相机取景框页面还包括第二界面组件，第二界面组件用于展示针对预览图像添加的目标视觉特效，本实施例提供的方法中，还包括：基于第二界面组件所展示的目标视觉特效，生成预览图像对应的特效图像。
图6为本公开实施例提供的另一种相机取景框页面的示意图，如图6所示，在相机取景框页面的第二目标位置，设置有第二界面组件，第二界面组件用于展示针对预览图像添加的目标视觉特效，更具体地，例如美肤特效、贴纸特效等。一种可能的实现方式中，第二界面组件响应用户指令而改变其所显示的目标视觉特效，例如，用户点击该第二界面组件后，弹出显示多个备选视觉特效，之后基于用户对备选视觉特效的选择操作，将其中一个作为目标视觉特效。
进一步地，基于第二界面组件所展示的目标视觉特效，终端设备基于该目标视觉特效对第一界面组件所对应的预览图像进行渲染，从而生成带有该目标视觉特效的图像，即特效图像。图7为本公开实施例提供的一种生成特效图像的示意图，如图7所示，示例性地，第二界面组件所展示的目标视觉特效为为用户头像增加虚拟装饰物(例如图中所示的皇冠)的贴纸特效，而第一界面组件所对应的预览图像，也即，由媒体数据库内的目标媒体数据生成的预览图像，为包含用户头像的照片，则基于目标视觉特效对预览图像进行渲染后，生成的特效图像为：包含带有虚拟装饰物的用户头像的照片。
相应的，基于上述实现方式，步骤S102的具体实现方法包括：基于第一界面组件，在第一时间段内，展示至少两帧预览图像分别对应的特效图像。
本实施例中，在相机取景框页面内设置第一界面组件的基础上，进一步增加用于显示预览图像的视觉特效的第二界面组件，通过第二界面组件显示和设置目标视觉特效，使第一界面组件能够显示添加了相应的视觉特效的预览图像，从而使用户通过观察相机取景框页面，可以进一步观察到对媒体数据库内的媒体数据添加视觉特效后的效果，从而帮助用户决定是否采用媒体数据库页面内的媒体数据生成最终的输出媒体数据执行后续的编辑、上传等步骤。进一步地减少了用户操作步骤，提高了交互效率，缩短了生成输出媒体数据的耗时。
参考图8，图8为本公开实施例提供的图像预览方法的流程示意图二。本实施例在图3所示实施例的基础上，增加了确定媒体数据库页面内的目标媒体数据的步骤，以及生成输出媒体数据的步骤，该图像预览方法包括：
步骤S201：显示前置页面，并获取前置页面对应的页面信息，页面信息表征前置页面对应的页面主题，前置页面内包括第三界面组件，第三界面组件用于生成与页面主题对应的用户自制媒体。
步骤S202：响应于针对第三界面组件的第一触发操作，生成相机启动指令，相机启动指令中包括页面信息。
示例性地，前置页面即触发相机取景框页面的页面，前置页面内设置有第三界面组件，例如图2所示实施例中客户端内设置的名称为“上传我的作品”触发控件，当用户点击该触发控件后，生成相机启动指令，并直接启动相机取景框页面，而无需展示图2所示实施例中包含“拍摄视频/照片”和“加载视频/照片”两个控件的页面，从而简化操作流程。具体实现可参见图2及图4对应实施例中的介绍，此处不再赘述。
进一步地，前置页面配置有对应的页面信息，终端设备可以通过客户端程序，获得前置页面对应的页面信息。其中，示例性地，不同的前置页面可以对应不同的页面信息，页面信息表征前置页面对应的页面主题。例如，前置页面#1是应用中的汽车板块讨论区，对应的页面主题为“汽车主题”，前置页面#1对应的页面信息为info_1；前置页面#2是应用中的旅游板块讨论区，对应的页面主题为“旅游主题”，前置页面#2对应的页面信息为info_2。示例性地，页面信息与其所表征的页面主题具有固定的映射关系，该映射关系可以是预设的，因此，页面信息可以为上述示例中的抽象标识。进一步地，该页面信息可以通过前置页面的访问地址确定的。在响应于针对第三界面组件的第一触发操作时，基于该前置页面对应的页面信息，生成对应的相机启动指令，使相机启动指令中能够包含该前置页面的页面信息。
步骤S203：响应于相机启动指令，启动相机取景框页面，相机取景框页面内包括第一界面组件和第二界面组件。
步骤S204：根据相机启动指令中的页面信息，生成目标场景信息，目标场景信息表征媒体数据的目标内容类别。
步骤S205：根据目标场景信息，确定目标媒体数据，并基于目标媒体数据，生成至少两帧预览图像。
示例性地，在响应该相机启动指令后，调用相机取景框页面对应的启动方法，并进行初始化，加载该相机取景框页面，其中，在初始化阶段，相机取景框页面内的第一界面组件和第二界面组件可以不加载数据，在初始化阶段结束后，确定并加载第一界面组件和第二界面组件对应的数据，从而使第一界面组件和第二界面组件显示对应的内容。
其中，示例性地，相机启动指令中包含有页面信息，页面信息表征前置页面对应的页面主题，基于该页面信息以及预设的映射关系，得到对应的目标场景信息，目标场景信息表征媒体数据的目标内容类别，内容类别例如包括，车辆、房屋、风景、人像等。页面信息与场景信息之间的映射关系例如为，当页面信息表征的前置页面的页面主题为“汽车主题”，则其所映射的目标内容类别为“车辆”、“公路”。当页面信息表征的前置页面的页面主题为“旅游主题”，则其所映射的目标内容类别为“风景”、“人像”。其中，场景信息也可以基于抽象标识表征，具体可根据需要设置。由于场景信息所表征的媒体数据的内容类别，可以在对媒体数据进行识别的基础上，对媒体数据进行分类，例如识别出媒体数据中关于“人像”、“风景”的视频和照片，因此，基于目标场景信息所表征的目标内容类别，可以得到对应的、归属于该目标内容类别下的媒体数据，即目标媒体数据，进而，根据目标媒体数据得到至少两帧预览图像，具体实现方法在图3所示实施例中已进行介绍，此处不再赘述。
步骤S206：基于目标场景信息，获得目标视觉特效。
步骤S207：基于第二界面组件，展示针对预览图像添加的目标视觉特效。
示例性地，基于目标场景信息，可以进一步的确定与之匹配的视觉特效，即目标视觉特效，例如，当目标场景信息对应的目标内容类别为“风景”，则使用用于添加“光晕”特效的视觉特效A；当目标场景信息对应的目标内容类别为“人物”，则使用用于添加“美肤”特效的视觉特效B；即通过不同的目标场景信息和预设的映射关系，可以确定与之匹配的目标视觉特效，具体地映射关系实现可以基于具体需要设置，不再赘述。
进一步地，确定目标视觉特效后，在用于展示视觉特效的第二界面组件内，显示该目标视觉特效对应的标识，例如特效图标、特效文字等，从而实现对该目标视觉特效的展示和设置，实现与页面主题匹配的视觉特效的自动推荐，减少用户操作，提高交互效率。
步骤S208：基于第二界面组件所展示的目标视觉特效，生成预览图像对应的特效图像。
步骤S209：基于第一界面组件，在第一时间段内，展示至少两帧预览图像分别对应的特效图像。
进一步地，在确定目标视觉特效和预览图像后，基于目标视觉特效预览图像进行渲染，从而生成带有视觉特效的预览图像，即特效图像。其中，基于上述步骤，由于目标视觉特效和预览图像，是基于同一组目标场景信息确定的，因此，可以保证目标视觉特效和预览图像在主体场景维度的一致性，使生成的特效图像更加合理，与有经验用户手动设置和选取的结果也更加相似，因此，对于无经验用户更加友好，提高用户在使用现有媒体数据进行内容创造的情况下，提高产出的作品的质量和效率。
进一步地，可选地，在步骤S209之后，还包括：
步骤S210：响应于针对第一界面组件的第二触发操作，生成输出媒体数据，其中，第二触发操作指示第一界面组件内的目标预览图像，输出媒体数据是基于目标预览图像或目标预览图像对应的目标媒体数据生成的。
步骤S211：将输出媒体数据显示在相机取景框页面的前置页面。
示例性地，由于第一界面组件内的预览图像是动态变化的，当终端设备在第一时刻检测到针对第一界面组件的第二触发操作时，例如对第一界面组件的点击操作，则该第一时刻下，第一界面组件内显示的预览图像，即为第二触发操作对应的目标预览图像。之后，获取该目标预览图像对应的目标媒体数据，例如为视频或照片，将目标媒体数据进行压缩、尺寸调整、添加视觉特效等处理步骤后，生成输出媒体数据；或者，直接将该目标媒体数据作为输出媒体数据。再之后，终端设备运行的客户端返回前置页面，并将输出媒体数据显示在该前置页面内，从而完成加载输出媒体数据的过程。之后基于具体的需要，可以进一步对输出媒体数据进行编辑、上传，此处不再赘述。
图9为本公开实施例提供的一种加载输出媒体数据的过程示意图，如图9所示，示例性地，在前置页面点击“加载图片”按钮(第三界面组件)后，进入相机取景框页面，在相机取景框页面内，第一界面组件动态显示多帧预览图像，例如在第一时刻，第一界面组件内显示预览图像P1、在第二时刻，第一界面组件内显示预览图像P2、在第三时刻，第一界面组件内显示预览图像P3，其中，在第三时刻下，终端设备检测到针对第一界面组件的第三触发操作，例如用户的点击操作，之后，终端设备自动获取该预览图像P1对 应的目标媒体数据data_1，并对该目标媒体数据data_1进行视觉特效渲染，生成带有视觉渲染特效的媒体数据，即输出媒体数据，加载该输出媒体数据并显示在前置页面内，可选地，同时在第三界面组件显示“已加载”字样。
由于本实施例步骤中第一界面组件所显示的预览图像，是基于场景信息动态自动确定的，并非用户手动选择的，并且在添加有视觉特效的情况，会导致用户仅通过观察预览图像，很难或无法通过媒体数据库页面准确找到对应的目标媒体数据的问题，进而导致基于目标媒体数据加载输出媒体数据的过程中，增加额外的耗时，降低输出媒体数据的加载效率。本实施例步骤中，通过响应针对第一界面组件的第二触发操作，直接确定目标预览图像，并在前置页面加载对应的输出媒体数据。使用户通过观察第一界面组件内显示的预览图像，结合第二触发操作，即可完成加载输出媒体数据的过程，无需启动媒体数据库页面进行手动查找和选择目标媒体数据，提高了输出媒体数据的加载效率，减少耗时。
本实施例中，步骤S203的实现方式与本公开图3所示实施例中的步骤S101的实现方式类似，具体可参见图3所示实施例中的对应介绍，在此不再一一赘述。
