Mobile device, operating method of mobile device, and non-transitory computer readable storage medium

A mobile device comprising:

• a capturing circuit;
• a display component;
• one or more processing circuit electrically connected to the capturing component and the display component;
• a memory electrically connected to the one or more processing circuit;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processing circuit, the one or more programs comprising instructions for:
• controlling the capturing component to capture a preview image;
• controlling the display component to display the preview image;
• detecting a photograph in the preview image;
• in response to the photograph being detected in the preview image, searching a video file corresponding to the photograph in a database;
• and
• in response to a video file corresponding to the photograph being searched, playing a video of the searched video file over at least a part of the displayed preview image,
• wherein the one or more programs further comprise instructions for:
• calculating a corresponding relationship between vertexes of the photograph and vertexes of the video of the searched video file;
• and
• playing the video with a shape and a size changed according to the corresponding relationship between the vertexes of the photograph and the vertexes of the video of the searched video file at a position of the photograph in the preview image.

A non-transitory computer readable storage medium storing one or more programs comprising instructions, which when executed, causes one or more processing components to perform operations comprising:

• capturing a preview image;
• displaying the preview image;
• detecting a photograph in the preview image;
• in response to the photograph being detected in the preview image, searching a video file corresponding to the photograph in a database;
• and
• in response to a video file corresponding to the photograph being searched, playing a video of the searched video file over at least a part of the displayed preview image,
• wherein the operation of playing the video of the searched video file over the at least a part of the displayed preview image comprises:
• calculating a corresponding relationship between vertexes of the photograph and vertexes of the video of the searched video file;
• and
• playing the video with a shape and a size changed according to the corresponding relationship between the vertexes of the photograph and the vertexes of the video of the searched video file at a position of the photograph in the preview image.
