Panoramic Camera Motion Guidance via Image Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital image photography methods for capturing panoramic images require user sophistication and additional hardware for accurate alignment, making the process cumbersome and less accessible.
Innovation Solution
A method that compares current and previous images in real-time to detect motion information, allowing for automatic or manual adjustment of the camera movement based on pre-set references, enabling easier and more accurate panoramic image capture without additional apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a tripod or additional hardware is used for panoramic photographing, then alignment accuracy is improved, but device complexity increases
Solution Approach 1:
The photographing apparatus uses its own image capture unit and processor to automatically detect motion information from captured images and generate guidance information, eliminating the need for external tripods or alignment tools. The system serves itself by using its captured images to guide subsequent shooting positions.
Solution Approach 2:
The patent replaces mechanical alignment systems (tripods, protractors) with an electronic/image-processing-based system that uses the image capture unit and processor to detect motion and calculate guidance information, substituting mechanical measurement with electronic image analysis.
2Ease of operation
If manual alignment methods are used for panoramic photographing, then ease of operation is improved, but manufacturing precision deteriorates
Solution Approach 1:
The system captures images, processes them to detect motion information, generates guidance information based on detected motion, and uses this guidance to control subsequent shooting. This closed-loop feedback ensures both ease of operation and high alignment precision.
Solution Approach 2:
The processor detects motion information and generates guidance information before the user captures the next image, providing advance direction for the subsequent shot. This preliminary action ensures accurate alignment is achieved without requiring complex manual operations during the actual shooting.
3Measurement precision
If multiple images are captured with sufficient overlap for panoramic stitching, then alignment accuracy is improved, but loss of time increases
Solution Approach 1:
The patent replaces time-consuming manual overlap adjustment with an electronic system that automatically detects motion from captured images and calculates precise guidance information, significantly reducing the time required while maintaining or improving alignment accuracy.

AI summary
Disclosed is a method for photographing a panoramic image. The method includes comparing an current image input with a previous image to obtain a motion information of a corresponding photographing apparatus, when photographing respective images forming the panoramic image, recognizing a degree of movement of the corresponding photographing apparatus at least based on the obtained motion information, and photographing corresponding image by a manual input or automatically when the recognized degree of movement is satisfied with a pre-set movement distance reference.
