Multi-Camera Electronic Device Position Indicator for Autofocus Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems face limitations in performing specific operations like autofocus and photometry stably across the entire live view image, due to variations in lens mounts.
Innovation Solution
An electronic device with a processor and memory that acquires images from multiple optical systems, displays these images, and allows users to easily designate positions for specific operations within the AF-capable area by changing the form of an indicator item.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a circular fish-eye lens is used to capture a wide field of view, then the coverage area is improved, but the area where specific operations (AF, photometry) can be suitably performed is limited to a specific region
Solution Approach 1:
The display image is divided into two distinct regions: a predetermined area (AF-capable area) where specific operations can be suitably performed, and an area outside the predetermined area. This segmentation allows the system to provide different visual feedback for different regions, guiding users to operate within the reliable zone while maintaining wide coverage.
Solution Approach 2:
Different visual forms are applied to the item depending on its location: a first form (e.g., normal cursor) is displayed when the item is within the predetermined area, and a second form (e.g., changed appearance or color) is displayed when outside. This local differentiation provides spatially varying information quality to guide user operation.
2Ease of operation
If the item form is changed based on position, then user guidance is improved, but display complexity increases
Solution Approach 1:
The item's visual form changes based on its position relative to the predetermined area. This could involve color changes, shape changes, or other visual modifications that provide intuitive feedback to users about operational suitability without requiring complex additional displays or interfaces.

AI summary
An electronic device executes acquisition processing to acquire an image having a plurality of image areas respectively captured via a plurality of optical systems, executes display control processing to perform control so that a display image based on the acquire image is displayed and perform control so that an item indicating a position in the display image is displayed, and executes receiving processing to receive a user operation for changing a position of the item, wherein in the display control processing, control is performed so that the item is displayed in a first form in a case where the position of the item corresponds to a position in a predetermined area of the image, and control is performed so that the item is displayed in a second form in a case where the position of the item corresponds to a position outside the predetermined area.
