Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Panoramic image quality is compromised due to the complexity and inconvenience of capturing multiple overlapping photographs, which increases the difficulty in stitching them together effectively.
Innovation Solution
A method for electronic devices that determines predefined target positions in a three-dimensional space, uses navigators to guide users in capturing target photographs, and displays preview images in different modes to facilitate accurate alignment and stitching, allowing for efficient capture and projection of panoramic images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If more photographs are captured to improve panoramic image quality, then the quality of the stitched panoramic image becomes better, but the complexity and inconvenience of the photographing process increases
Solution Approach 1:
The system pre-calculates and determines the optimal number and positions of target photographs needed for panoramic stitching before the user starts capturing. The navigator displays these predetermined target positions, guiding the user to capture only the necessary number of photographs, thereby avoiding the need to capture excessive images while ensuring sufficient quality for stitching.
Solution Approach 2:
The navigator provides real-time feedback by displaying the capturing status of target photographs. It shows which target positions have been captured and which remain, allowing the user to track progress and understand how many more photographs are needed. This feedback mechanism reduces uncertainty and helps users complete the capture process efficiently without unnecessary photographs.
2Manufacturing precision
If more photographs are captured to improve panoramic image quality, then the quality of the stitched panoramic image becomes better, but the inconvenience of the photographing process increases
Solution Approach 1:
The navigator acts as an intermediary between the user and the complex stitching process. It translates the technical requirements for panoramic stitching into user-friendly visual guidance, showing target positions and capture status. This intermediary interface simplifies the user's task by providing clear instructions without requiring the user to understand the underlying stitching algorithms or determine optimal photograph numbers themselves.
Solution Approach 2:
The system performs preliminary calculations to determine the exact number and positions of target photographs needed before the user begins capturing. This pre-planning eliminates the need for users to experiment with different numbers of photographs or worry about capturing enough images, making the process more convenient and predictable.
3Manufacturing precision
If multiple photographs are captured for panoramic stitching, then the panoramic image quality improves, but the difficulty of stitching them together increases
Solution Approach 1:
The panoramic capture process is segmented into discrete target positions that are pre-calculated and displayed in the navigator. Instead of requiring users to capture arbitrary numbers of overlapping photographs, the system divides the panoramic field into specific target zones. This segmentation provides clear structure for the stitching process, as the algorithm only needs to align photographs from these predetermined positions, reducing the complexity of detecting and measuring overlaps.
Solution Approach 2:
The system performs preliminary planning by calculating optimal target positions and overlap regions before capture begins. This pre-computation of stitching parameters simplifies the actual stitching process, as the algorithm already knows which regions to align and how much overlap is needed, reducing the difficulty of detecting and measuring relationships between multiple photographs.

AI summary
A panorama photographing method, a panorama displaying method and an image capturing method are used in an electronic device. The photographing method includes the following steps. Firstly, a plurality of predefined target positions required to produce a panoramic image are determined. Then, a navigator comprising a plurality of indications representing the plurality of predefined target positions is shown. A plurality of target photographs corresponding to the plurality of predefined target positions are captured and appearance of the plurality of indications according to a capturing status of the plurality of target photographs is changed. Afterwards, the panoramic image is generated according to the plurality of target photographs.
