Dual Camera Image Combining for Sharpness and User Experience
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dual-camera systems lack intelligent image combining capabilities, resulting in poor user experience due to inadequate sharpness enhancement in overlapping image areas.
Innovation Solution
A control method and device that utilize a wide-angle camera and telephoto camera with an actuator to adjust the relative location of the overlapping field of view, allowing for user-input driven zooming and image capture, followed by combining wide-angle and telephoto images to enhance sharpness in the overlapped area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image combining is performed in dual-camera systems, then sharpness of overlapped portions can be enhanced, but the system lacks intelligent control capabilities resulting in poor user experience
Solution Approach 1:
The system automatically detects user zooming operations and intelligently triggers image combining without requiring manual user configuration. The control device monitors preview image operations and autonomously determines when to activate the telephoto camera and perform image fusion, making the sharpness enhancement process transparent and effortless for users.
Solution Approach 2:
The system continuously monitors user interactions with the preview image (such as zooming gestures) and uses this feedback to dynamically adjust camera operations. When zooming is detected, the system responds by activating the telephoto camera and performing image combining, creating a closed-loop control system that adapts to user needs in real-time.
2Productivity
If telephoto camera is always on to provide cached telephoto image, then image combining can be performed quickly, but energy consumption increases
Solution Approach 1:
Instead of continuously operating the telephoto camera, the system activates it periodically only when zooming operations are detected during preview image display. The telephoto camera is turned on temporarily to capture the needed cached image, then powered down, creating a pulsed operation pattern that balances performance with energy conservation.
Solution Approach 2:
The system captures the cached telephoto image in advance when zooming is detected, before the actual image combining is needed. This preliminary capture allows the telephoto camera to be activated briefly to prepare the image data, then powered down while the main processing and combining operations proceed using the pre-captured cache.

AI summary
The present disclosure provides a control method, a control device and an electronic device. The wide-angle camera is started first. Then, the displayer is controlled to display a cached wide-angle image as a preview image. Next, a designated area is identified and the telephoto camera is started during zooming the preview image. Further, the actuator is controlled such that a cached telephoto image is located in the designated area, and the wide-angle camera and telephoto camera are controlled to image respectively. Finally, the wide-angle image and telephoto image are combined. With the control method and device and the electronic device in the present disclosure, the telephoto camera may image the designated area when the user zooms the designated area of the cached wide-angle image, thereby enhancing sharpness of the designated area and improving the user experience.
