Description

一种图像处理的方法及装置
技术领域
本发明涉及计算机及图像处理技术领域, 尤其涉及一种图像处理方法及 装置。 背景技术
随着通信技术和增值业务的发展, 在移动终端上的应用越来越丰富, 用 户体验越来越好。 其中 "预览" 是一个非常重要的子应用, 在很多应用程序 中都有采用。 通过 "预览" 功能, 用户可以在确定最终的应用之前, 看到实 施该应用的效果。
目前, "预览" 子应用的实现是将选择的目标应用的图片 "叠加" 在一 个模拟的环境上, 提供一个 "类似于"真实应用场景的模拟样式。 也就是说, 预先设置一背景图片, 然后将目标应用的图片 "叠加 " 在该背景图片上, 参 见图 1所示, 以桌面时钟应用为例。
由此可见, 预先设置的背景图片虽然包括其它应用的图标, 但是这些图 标只是为了模拟真实环境, 并非用户设置的真实应用的图标。 所以该背景图 片与目标应用的图片实际所在应用场景是有区别的, 预览的不是真实的应用 场景, 影响预览的显示效果。 并且, 背景图片中其它应用的图标的显著性高 于目标应用的图片, 或者两者的显著性持平, 则影响目标应用的图片的预览 效果, 导致用户不容易发现目标应用的图片。 发明内容
本发明实施例提供一种图像处理方法及装置, 用于提高图像的显示效 果。

例如, 背景图片为未应用所述目标应用时实际环境的图片; 在预览环境 中输出目标应用的图片与背景图片的组合的步骤包括: 将目标应用的图片叠 加在背景图片上后, 在预览环境中输出叠加后的图片。 尤其在只对背景图片 进行图像处理的场景下, 本实施例在图像处理过程中主要完成背景图片修改 和将目标应用的图片叠加在背景图片上两个步骤, 筒化操作流程。
或者, 例如, 背景图片为从应用了目标应用后的实际环境的图片中裁剪 掉目标应用的图片所在区域后的图片; 在预览环境中输出目标应用的图片与 背景图片的组合的步骤包括: 将目标应用的图片填充到背景图片的裁剪区域 后, 在预览环境中输出填充后的图片。 尤其在只对背景图片进行图像处理的 场景下, 本实施例虽然增加了裁剪步骤, 但是在修改背景图片时减少了图像 修改面积。

本发明实施例通过修改目标应用的图片和 /或背景图片,使得目标应用的 图片更加醒目,提高预览图像的显示效果,便于用户更清晰的看到预览效果。 参见图 2 , 本实施例中图像处理的主要方法流程如下:
步骤 201 : 根据预览事件的触发, 确定目标应用的图片和目标应用应在 的实际环境。
步骤 202: 根据目标应用应在的实际环境获得背景图片。
步骤 203 : 对目标应用的图片和背景图片中的至少一个图片进行图像处 理, 使目标应用的图片的显著性高于背景图片。
步骤 204: 在预览环境中输出目标应用的图片与背景图片的组合。
本实施例中可以修改目标应用的图片或背景图片或两者都修改, 只要目 标应用的图片的显著性高于背景图片即可。 显著性体现在灰度、 亮度、 色度 和透明度中的至少一项因素, 即目标应用的图片在亮度和色度中至少一个方 面的值高于背景图片, 在灰度和透明度中至少一个方面的值低于背景图片。 具体修改哪项或哪几项因素的值, 可以视图片的格式和具体因素的值而定。 较佳的方案是降低背景图片的透明度, 这样可以保证目标应用的图片的真实 性, 又可以突显目标应用的图片, 使用户在预览时可以真实直观的看到目标 应用的图片的显示效果。
另外, 预先判断背景图片的灰度、 亮度、 色度和透明度中的至少一项因 素的值是否大于目标应用的图片的相应项因素的值与预设幅度值的差值。 若 是, 则将背景图片的灰度、 亮度、 色度和透明度中的至少一项因素的值降低 到目标应用的图片的相应项因素的值与预设幅度值的差值或该差值以下。 否 则可以不进行修改。 其中, 关于灰度、 亮度、 色度和透明度的预设的幅度值 的取值范围为目标应用的图片在灰度、 亮度、 色度和透明度方面取值的 10%~20%。
本实施例中的背景图片为未应用所述目标应用时实际环境的图片; 此 时, 在预览环境中输出目标应用的图片与背景图片的组合的步骤包括: 将目 标应用的图片叠加在背景图片上后, 在预览环境中输出叠加后的图片。
或者, 背景图片为从应用了目标应用后的实际环境的图片中裁剪掉目标 应用的图片后的图片; 此时, 在预览环境中输出目标应用的图片与背景图片 的组合的步骤包括: 将目标应用的图片填充到背景图片的裁剪区域后, 在预 览环境中输出填充后的图片。
以上介绍了多种可能的实现方式, 下面通过两个典型实施例来详细介绍 实现过程。
参见图 3 , 本实施例中背景图片为未应用所述目标应用时实际环境的图 片时的图像处理方法:
步骤 301 : 根据预览事件的触发, 确定目标应用的图片和目标应用应在 的实际环境。 其中, 需要确定目标应用的图片应处的位置, 如位于主页第一 页或主页第二页或其它某个应用的访问首页等。还需确定该页面下的其它图 标或图片等。 其中, 以桌面时间工具为例, 用户从图 4所示的备选样式中选 择了一种时钟样式, 选择的时钟样式参见图 5所示。
步骤 302: 根据目标应用应在的实际环境获得背景图片。 该背景图片为 未应用所述目标应用时实际环境的图片, 该背景图片包括其它应用的图标或 图片, 以桌面时间工具位于主页第一页为例, 参见图 6所示。
步骤 303 : 判断背景图片的透明度是否小于目标应用的图片的透明度与 预设幅度值的和值, 若是, 则继续步骤 304, 否则继续步骤 305。
步骤 304: 将背景图片的透明度提高到目标应用的图片的透明度与预设 幅度值的和值。
步骤 305: 将目标应用的图片叠加在背景图片上后, 在预览环境中输出 叠加后的图片。 以桌面时间工具为例, 处理后的图片参见图 7所示, 经处理 后的背景图片是以灰度图方式显示, 桌面时间工具是以实际值显示。 处 理后的图片可以全屏显示, 也可以非全屏显示。
本实施例对背景图片的修改, 修改的是背景图片在显示时的像素值, 不 改变背景图片本身, 预览后确定采用该目标应用时, 以背景图片的实际值显 示。 以桌面时间工具为例, 确定采用该目标应用时的图片参见图 8所示, 此 时, 图 8 中的背景图片并非以图 7中的灰度图方式显示, 而是以背景图 片的实际值显示。
参见图 9, 本实施例中背景图片为从应用了目标应用后的实际环境的图 片中裁剪掉目标应用的图片后的图片时的图像处理方法:
步骤 901 : 根据预览事件的触发, 确定目标应用的图片和目标应用应在 的实际环境。
步骤 902: 根据目标应用应在的实际环境获得背景图片。 该背景图片包 括目标应用的图片。 步骤 903 : 从背景图片中裁剪掉目标应用的图片, 获得裁剪后的背景图 片, 以桌面时间工具位于主页第一页为例, 参见图 10所示。
步骤 904: 判断背景图片的灰度是否小于目标应用的图片的灰度与预设 幅度值的和值, 若是, 则继续步骤 905 , 否则继续步骤 906。
步骤 905: 将背景图片的灰度提高到目标应用的图片的灰度与预设幅度 值的和值。
步骤 906: 预览输出模块将目标应用的图片填充到背景图片的裁剪区域 后, 在预览环境中输出填充后的图片。
本实施例对背景图片的修改, 修改的是背景图片在显示时的像素值, 不 改变背景图片本身, 预览后确定采用该目标应用时, 以背景图片的实际值显 示。
通过以上描述了解了图像处理的实现过程, 该过程可由装置实现, 下面 对该装置的内部结构和功能进行介绍。
参见图 11 , 本实施例中的装置包括: 环境虚拟模块 1101、 背景图片生 成模块 1102、 图片处理模块 1103和预览输出模块 1104。 该装置可具体为手 机或计算机等。
环境虚拟模块 1101 用于根据预览事件的触发, 确定目标应用的图片和 目标应用应在的实际环境。
背景图片生成模块 1102用于根据目标应用应在的实际环境获得背景图 片。
图片处理模块 1103 用于对目标应用的图片和背景图片中的至少一个图 片进行图像处理, 使目标应用的图片的显著性高于背景图片。 具体的, 图片 处理模块 1103修改所述至少一个图片的灰度、 亮度、 色度和透明度中的至 少一项因素的值, 使目标应用的图片在亮度、 色度和透明度中至少一个方面 的值高于背景图片。 较佳的, 图片处理模块 1103 降低背景图片的透明度, 至少使降低后的背景图片的透明度低于目标应用的图片的透明度。 并且, 图 片处理模块 1103还用于判断背景图片的灰度、 亮度、 色度和透明度中的至 少一项因素的值是否大于目标应用的图片的相应项因素的值与预设幅度值 的差值; 若是, 则将背景图片的灰度、 亮度、 色度和透明度中的至少一项因 素的值降低到目标应用的图片的相应项因素的值与预设幅度值的差值或该 差值以下。
预览输出模块 1104用于在预览环境中输出目标应用的图片与背景图片 的组合。 具体的, 背景图片为未应用所述目标应用时实际环境的图片; 预览 输出模块 1104将目标应用的图片叠加在背景图片上后, 在预览环境中输出 叠加后的图片。 或者, 背景图片为从应用了目标应用后的实际环境的图片中 裁剪掉目标应用的图片后的图片; 预览输出模块 1104将目标应用的图片填 充到背景图片的裁剪区域后, 在预览环境中输出填充后的图片。
以手机为例, 手机包括触摸屏、 处理器和存储器, 参见图 12所示。 处 理器通过触摸屏获得预览事件的触发, 遍历存储器中的记录, 确定目标应用 的图片和目标应用应在的实际环境, 并获得该实际环境下的各种资源(包括 其它应用的图标或图片等)。 处理器进一步完成背景图片生成模块 1102、 图 片处理模块 1103和预览输出模块 1104的功能。
