Color-Coded Multi-Region Video Recording And Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video capture technologies lack convenience in switching and displaying cut-out videos from multiple subjects without superimposing flags and maintaining optical zoom limitations.
Innovation Solution
A display method for an imaging apparatus that allows setting multiple regions, selecting a recording region, switching it during recording, and displaying flags for different regions while limiting optical zoom, enabling easy tracking and switching of video regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple set regions are displayed with flags to indicate positions, then region identification is improved, but display complexity and visual clutter increase
Solution Approach 1:
The patent applies color changes by displaying flags in different colors to represent different set regions. Each flag's color corresponds to a specific region, enabling intuitive region identification without complex labels or overlays. This resolves the contradiction by providing clear region differentiation through simple visual color cues.
2Adaptability or versatility
If optical zoom is allowed during recording, then imaging flexibility is improved, but reference region stability deteriorates
Solution Approach 1:
The patent segments the imaging functions by separating the reference region (which remains fixed and stable) from the set regions (which can be selectively zoomed). The reference region serves as a stable background frame, while electronic zoom can be applied to specific set regions without affecting the overall reference frame. This allows imaging flexibility within set regions while maintaining reference region stability.
3Quantity of substance
If set regions are superimposed to show multiple views, then information density is improved, but region distinction deteriorates
Solution Approach 1:
The patent uses color-coded flags to distinguish different set regions even when multiple regions are displayed simultaneously. Each region is associated with a unique color, allowing users to clearly differentiate between regions while maintaining high information density on the display. This resolves the contradiction by providing both multi-region display and clear region distinction through color coding.

AI summary
A display method of displaying a video captured by an imaging apparatus includes setting a plurality of set regions in a reference region which is an imaging region of a reference video, selecting a recording region, which is a region of a record video to be recorded, from among the plurality of set regions, reselecting the recording region from among the plurality of set regions to switch the recording region after the selection step is performed, recording the record video on a recording medium, displaying a plurality of set videos which are videos of the plurality of set regions, and performing a control process relating to a change of the reference region at least after the reference region is determined. The control process includes a process of maintaining a state in which an optical zoom function of the imaging apparatus is limited during the recording step.
