Image Processing Device Using Difference Information for Resolution Synthesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image processing, capturing high-resolution images continuously results in poor imaging effects and image quality, along with increased power consumption in terminal devices.
Innovation Solution
An image processing method that involves acquiring a first low-resolution image and a second high-resolution image, determining difference information between target and reference pixels, and applying an image differencing process to a predetermined low-resolution image to generate a high-resolution target image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high-resolution images are continuously captured, then image resolution is improved, but power consumption increases
Solution Approach 1:
The patent applies partial action by capturing only low-resolution images continuously and selectively capturing high-resolution images only when difference information indicates actual scene changes. This partial use of high-resolution capture avoids continuous high-power consumption while maintaining image quality when needed
Solution Approach 2:
The patent changes the resolution parameter dynamically based on scene conditions. By using difference information comparison, the system adjusts between low-resolution (power-saving) and high-resolution (quality) modes, optimizing the balance between power consumption and image quality
2Measurement precision
If high-resolution images are continuously captured, then image resolution is improved, but image quality deteriorates
Solution Approach 1:
The patent uses difference information as feedback to control image capture quality. By comparing current low-resolution images with reference images and calculating difference values, the system determines whether scene changes warrant high-resolution capture, creating a feedback loop that optimizes image quality
Solution Approach 2:
The patent applies partial action by using high-resolution capture only when necessary (when difference information exceeds thresholds indicating real scene changes). For static or slowly changing scenes, low-resolution capture suffices, preventing quality degradation from continuous high-resolution imaging
3Use of energy by moving object
If low-resolution images are used, then power consumption is reduced, but image resolution decreases
Solution Approach 1:
The patent introduces difference information as an intermediary between low-resolution and high-resolution imaging. This intermediary mechanism allows the system to use power-efficient low-resolution capture while still achieving high-resolution output when needed by leveraging the difference information to guide selective high-resolution capture
Solution Approach 2:
The patent dynamically changes the resolution parameter based on difference information analysis. When difference values indicate scene changes, the system switches to high-resolution mode; otherwise, it maintains low-resolution mode, optimizing the balance between power consumption and resolution

AI summary
An image processing method and apparatus, an electronic device, and a storage medium, relating to the technical field of image processing. The method includes: acquiring a first image and a second image, wherein a resolution of the second image is greater than a resolution of the first image; determining difference information between a target pixel in the second image and a reference pixel corresponding to the target pixel point in the first image; and acquire a target image with the same resolution as the second image by applying an image differencing process to a predetermined image with the same resolution as the first image based on the difference information. This method can obtain the target image based on the difference value information, and improve image quality.
