Selective Video Effect Encoding for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals can only apply a single effect to all frames of a moving picture, failing to meet users' complex needs for varying effects within a video, such as making a target object stand out from the background.
Innovation Solution
A method and mobile terminal configuration that allow users to input and apply effect information to specific objects within a moving picture, enabling selective application of effects to individual frames and objects, allowing for varied encoding of moving pictures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single effect is applied to all frames of a moving picture using conventional encoding methods, then the encoding process is simple and fast, but the user cannot satisfy complex needs for varying effects within different objects or regions of the video
Solution Approach 1:
The video picture is divided into multiple regions or objects, allowing different effect information to be applied to each segment. The encoding apparatus separates the picture into target objects and background regions, enabling independent effect application to each segment rather than applying a uniform effect to the entire frame.
Solution Approach 2:
Different effect information is applied to different regions or objects within the same video frame. The patent enables specifying different effects for target objects versus background areas, allowing local customization of effects rather than global uniform application.
2Ease of operation
If effect information is applied to specific target objects within a moving picture, then users can make target objects stand out from the background, but the encoding process becomes more complex
Solution Approach 1:
Effect information is specified in advance for target objects before the actual encoding process. The patent allows users to define effect parameters and target object regions beforehand, so that during encoding, the system simply applies the pre-defined effects without requiring complex real-time processing or user intervention.
3Adaptability or versatility
If conventional identical encoding is used for all frames, then the encoding process is straightforward, but the entire moving picture is formed in an identical effect which does not satisfy users' complex needs
Solution Approach 1:
The video encoding process is segmented into different processing paths: frames with target objects receive specialized effect processing, while frames without target objects use conventional encoding. This segmentation allows effect diversity where needed while maintaining encoding efficiency for standard frames.

AI summary
A method of encoding a moving picture of a mobile terminal by receiving a target object and encoding information including effect information to be applied to the target object from a user, and by applying the encoding information, and the mobile terminal using the method. Specifically, the method of encoding the moving picture of the mobile terminal including: receiving a target object and encoding information including effect information to be applied to the target object from a user; receiving a selection from a user with respect to whether to apply the encoding information when encoding the moving picture; and encoding the moving picture by applying the encoding information when the user selects to apply the encoding information.
