Moving Video Extraction Display With Full-View Position Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses struggle to allow users to perceive the position of an extraction range moving within an angle of view during video display.
Innovation Solution
A display method that includes acquiring a reference video, extracting an extraction video smaller than the angle of view, displaying the extraction video, and concurrently displaying a support video based on the positional relationship between the angle of view and the extraction range, with optional features like changing display sizes and aspect ratios, and user-controlled movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only the extraction video is displayed, then the display is simple and clear, but the user cannot perceive the position of the extraction range within the angle of view
Solution Approach 1:
The support video is nested within the extraction video display, creating a picture-in-picture effect where the support video (showing the entire angle of view) contains the extraction video (showing the extracted portion). This nesting structure allows position information to be displayed without adding a separate complex display element.
Solution Approach 2:
The support video acts as an intermediary element that bridges the gap between the extracted video content and the full angle of view context. It provides the positional reference information that the extraction video alone cannot provide, while maintaining visual coherence with the main display.
2Ease of operation
If the extraction range is moved automatically, then manual operation is avoided and tracking is enabled, but the user loses control over the extraction range position
Solution Approach 1:
The system implements dynamic control where the extraction range can automatically track subjects or be manually repositioned by the user. The support video dynamically updates to reflect the current extraction range position, enabling both automatic operation and user intervention without conflict.
Solution Approach 2:
The support video provides visual feedback to the user about the current extraction range position within the full angle of view. This feedback mechanism allows users to monitor automatic tracking operation and intervene when needed, combining ease of automatic operation with user control flexibility.

AI summary
Provided are a display method and a video recording method for a user to perceive a position of an extraction range moving within an angle of view, wherein the display method includes an acquisition step of acquiring a reference video that is a motion picture, an extraction step of extracting an extraction video set to be smaller than an angle of view of the reference video within the angle of view from the reference video, a movement step of moving an extraction range of the extraction video over time, a first display step of displaying the extraction video on a display device, and a second display step of displaying a support video based on a positional relationship between the angle of view and the extraction range on the display device, in which the second display step is executed during execution of the first display step.
