Dual Lens VR Camera Subject Selection via Dynamic Region Magnification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In dual lens VR cameras, selecting a desired subject using functions like Touch AF or Touch AE can be difficult due to the challenge of distinguishing the magnified subject's location within the entire image when two image regions are displayed side by side.
Innovation Solution
An electronic apparatus that acquires an image with two optical systems' image regions displayed side by side, and upon receiving a predetermined user operation, replaces one image region with a magnified version of the other, allowing for easier subject selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If dual lens display shows two image regions side by side, then wide angle of view and parallax are achieved, but subject selection becomes difficult
Solution Approach 1:
The display dynamically switches between showing two image regions side by side and showing a single magnified image region. When subject selection is needed, the system magnifies a specific region and displays it alone, making the selected subject larger and easier to identify. This dynamic adjustment resolves the contradiction by adapting the display mode to the current operational need.
Solution Approach 2:
The system segments the display into different functional modes: dual lens display mode for wide angle viewing and single region magnification mode for subject selection. By dividing the display functionality, the system can optimize for wide angle coverage when needed and for detailed subject examination when needed, resolving the contradiction between these two requirements.
2Loss of information
If two image regions are displayed side by side, then parallax information is preserved, but the magnified subject's location in the entire image is unclear
Solution Approach 1:
Before magnifying a specific image region, the system preliminarily identifies and selects the target region from the two available image regions. This preliminary selection ensures that the magnified region can be clearly associated with its location in the overall scene context, resolving the difficulty of detecting subject location while preserving parallax information through the selection process.
3Area of stationary object
If dual lens display is used, then wide coverage is achieved, but Touch AF and Touch AE functions become less effective
Solution Approach 1:
The display dynamically adjusts its content based on operational needs. When touch operations for autofocus or exposure are required, the system switches to displaying a single magnified image region, making touch operations more effective. When wide coverage is the priority, the system displays both image regions side by side. This dynamic adaptation resolves the contradiction between coverage area and operational effectiveness.

AI summary
An electronic apparatus includes a processor; and a memory storing a program which, when executed by the processor, causes the electronic apparatus to: acquire an image in which a first image region captured by using a first optical system and a second image region captured by using a second optical system are disposed side by side; display the first image region and the second image region on a display; receive a predetermined operation from a user; and in a case where the predetermined operation is received from the user, control such that a magnified image region, generated by magnifying a part of the first image region, is displayed instead of the second image region.
