Panorama Camera Preview Display and Motion Feedback Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image photographing devices require skillfulness and are complex to operate in panorama mode, as they lack user-friendly interfaces for previewing panoramic images and displaying motion data, making it difficult for users to maintain optimal velocity and direction for seamless image synthesis.
Innovation Solution
An image photographing device with a photographing unit, image processing unit, and display unit that generates preview panoramic data, displays motion vector information, and includes a control unit to stop panorama photography when deviations from predetermined angles or velocities occur, ensuring proper image synthesis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If panorama photographing is performed without preview functionality, then the device structure remains simple, but users cannot preview the panoramic image during capture making operation complex and skillful
Solution Approach 1:
The patent applies preliminary action by generating and displaying preview panoramic images during the capture process itself. The image processing unit creates a preview of the final panoramic image in real-time as images are captured, allowing users to see the result forming before completion. This eliminates the need for post-processing review and makes the operation intuitive and easy to control.
2Manufacturing precision
If motion vector display is not provided, then the device structure remains simple, but users cannot adjust their movement to maintain optimal velocity and direction for seamless synthesis
Solution Approach 1:
The patent implements feedback by displaying motion vectors that show the user's current movement direction and speed relative to the required optimal values. This visual feedback loop allows users to adjust their movement in real-time to maintain seamless image synthesis, directly improving image quality without requiring complex manual control mechanisms.
3Productivity
If multiple images are captured and processed to create panoramic images, then panoramic coverage is achieved, but the process is time-consuming and requires multiple capture operations
Solution Approach 1:
The patent applies continuity of useful action by capturing multiple images in continuous sequence during a single uninterrupted movement. The image processing unit continuously processes each captured image and integrates it into the growing panoramic composition in real-time, eliminating idle time between capture and processing operations, thus significantly improving productivity.
4Ease of operation
If real-time preview of panoramic images is displayed, then users can monitor synthesis progress, but processing resources and display bandwidth are consumed
Solution Approach 1:
The patent applies partial action by displaying only the essential information needed for user control - the preview panoramic image and motion vector data - rather than processing and displaying all captured image data in full detail. This selective processing approach provides sufficient feedback for easy operation while minimizing unnecessary processing resource consumption.
Data Source
AI summary
An image photographing device displays a preview panoramic image and data regarding moving velocity and direction of the image photographing device during panorama photographing in real time. The image photographing device includes a photographing unit to photograph a plurality of images, an image processing unit to convert the images photographed by the photographing unit into preview image data and to generate preview panorama data using the preview image data, and a display unit to simultaneously output a screen to display the preview image data, a screen to display a process of synthesizing the preview panorama data, a moving direction display screen indicating a relative difference between the moving direction of the image photographing device and a predetermined reference direction, and a moving velocity display screen indicating a relative difference between the moving velocity of the image photographing device and a predetermined reference velocity.
