Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If post-production methods are used to achieve image special effects, then special effects can be obtained, but real-time processing cannot be achieved
Solution Approach 1:
The patent applies preliminary action by pre-dividing the video into multiple image layers in advance, storing them in the data storage layer. When special effect processing is needed, these pre-prepared layers can be immediately retrieved and processed without time-consuming decomposition, thus achieving real-time processing while eliminating time delay.
2Adaptability or versatility
If multiple implementations are written to achieve multiple special effects, then various effects can be obtained, but the program becomes large and complicated
Solution Approach 1:
The patent implements universality by designing a unified special effect processing mechanism that can handle multiple types of special effects through a single implementation framework. The rendering layer provides general-purpose functions for layer manipulation, transparency adjustment, and blending operations that can produce various special effects without requiring separate programs for each effect type.
Solution Approach 2:
The patent applies segmentation by dividing the video into multiple independent image layers that can be separately manipulated. This segmentation allows complex special effects to be achieved through simple operations on individual layers, reducing program complexity while maintaining versatility. Each layer can be independently processed, stored, and recombined to create different effects.
3Adaptability or versatility
If developers write separate programs for each special effect, then specific effects can be achieved, but implementation becomes inflexible and time-consuming
Solution Approach 1:
The patent implements dynamics by creating a flexible rendering layer system where parameters such as transparency, layer positioning, and blending modes can be dynamically adjusted during runtime. This dynamic approach allows users to easily customize and modify special effects without rewriting programs, achieving both adaptability and ease of operation through programmable control.

AI summary
A method and a device for performing special effect processing on an image, an electronic apparatus, and a computer-readable storage medium are provided. The method includes: acquiring a video; determining a current image based on a current play progress of the video; acquiring a previous image of the current image from a data storage layer by an image acquisition unit of a rendering layer; superposing, by a special effect unit of the rendering layer, the previous image and the current image by superposing transparency of the previous image and transparency of the current image; outputting the superimposed image and displaying the superimposed image on the terminal screen.
