Dynamic Image Filter Adjustment via Gesture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image filtering technologies in terminal devices are limited by preset filter parameters, resulting in relatively simple and uniform filter effects, lacking diversity in image processing.
Innovation Solution
An image acquisition method and apparatus that allows users to input gestures to dynamically adjust filter parameters in real-time, enabling diverse filter effects by associating gestures with specific filter operations and parameters such as strength, color, size, and transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If preset filter parameters are used, then the filter operation is simple to implement, but the filter effect diversity is limited
Solution Approach 1:
The patent transforms static preset filter parameters into dynamic adjustable parameters. Users can perform gestures (swipe, rotate, zoom) on the filter icon to real-time adjust filter parameters such as strength, color, and size. This dynamic adjustment mechanism resolves the contradiction by enabling diverse filter effects while maintaining simple gesture-based operation.
Solution Approach 2:
The patent enables continuous parameter changes for filter operations. Instead of fixed preset values, users can adjust multiple parameters (strength, color, size, transparency) through gestures. This parameter change capability provides diverse filter effects while keeping the interface simple through intuitive gesture controls.
2Adaptability or versatility
If multiple filters with preset parameters are provided, then the filter types are limited, but the operation is straightforward
Solution Approach 1:
The patent makes the filter icon multi-functional. It serves both as a filter application button and as a control interface for adjusting filter parameters. Users can perform various gestures (swipe for strength, rotate for color, zoom for size) directly on the filter icon. This universal design provides diverse filter effects while maintaining ease of operation through the same intuitive interface.
Solution Approach 2:
The filter icon itself becomes the control mechanism. Instead of requiring separate controls for each parameter, the filter icon responds to user gestures to automatically adjust all filter parameters. This self-service approach enables diverse filter effects while keeping the operation simple and intuitive.

AI summary
This application provides an image acquisition method and apparatus, where the method includes: receiving an input gesture performed on an image captured by a camera; determining a filter parameter according to a current filter type and the gesture; performing a filter operation corresponding to the filter type on the image according to the filter parameter; and displaying, in real time, the image processed through the filter operation.
