Solution Overview
Problem
The generation of 'ghost' images occurs when fusing multiple frames of low-resolution images due to local motion caused by object movement between frames, leading to poor image quality in high-resolution images.
Innovation Solution
An image processing method using two camera lenses on the same side of a terminal, capturing images simultaneously and performing translation compensation with one image as a reference to fuse the images, thereby eliminating motion artifacts and enhancing resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple frames of low-resolution images are fused to generate a high-resolution image, then the resolution of the generated image is improved, but ghost images appear due to local motion between frames
Solution Approach 1:
The patent performs translation compensation on the second image using the first image as a reference before fusion. This preliminary alignment action corrects the relative position of objects between frames, ensuring that moving objects are properly registered during the fusion process, thereby eliminating ghost images while maintaining high resolution output
Solution Approach 2:
The patent uses the first image as a reference to calculate the translation vector and perform compensation on the second image. This feedback mechanism allows the system to detect and correct motion discrepancies between frames, preventing ghost image formation while preserving the resolution enhancement benefit
2Manufacturing precision
If images are captured at different times to enable fusion, then resolution enhancement is achieved, but motion artifacts occur due to object movement between capture moments
Solution Approach 1:
The patent performs translation compensation before the fusion process by using the first image as a reference to calculate and apply the translation vector to the second image. This preliminary correction ensures that objects from both images are properly aligned, preventing motion artifacts and maintaining high image quality in the final fused result
3Measurement precision
If translation compensation is performed using one image as reference, then motion alignment is improved, but device complexity increases due to additional processing steps
Solution Approach 1:
The patent uses the first image itself as the reference for translation compensation, allowing the system to perform self-alignment without requiring external reference data or complex calibration procedures. This self-service approach improves motion alignment while keeping the processing complexity manageable by utilizing existing image data

AI summary
The present invention relates to the field of image applications, and discloses an image processing method and apparatus, and a terminal, to resolve a technical problem of a "ghost" generated when multiple frames of low-resolution images are being fused to generate a high-resolution image in the prior art. The method is applied to a terminal that includes a first camera lens and a second camera lens, where the first camera lens and the second camera lens are located on a same side of the terminal. The method includes: obtaining a first image that is captured by the first camera lens and is about a first area, and a second image that is captured at a same moment by the second camera lens and is about a second area; performing translation compensation on the second image by using the first image as a reference image; and fusing the first image and the second image that is obtained after translation compensation is performed, to generate a third image, where a resolution of the third image is higher than a resolution of the first image and a resolution of the second image.
