Electronic Binoculars Dual Camera View Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic binoculars, when a subject moves out of the angle of view, users face difficulty in re-locating it due to the need to temporarily remove their gaze, as existing technologies do not effectively facilitate continuous observation across different angles of view.
Innovation Solution
The apparatus employs two image capturing units with different angles of view, where one unit captures a wider image than the other, and a control unit manages display devices for each eye, switching to the wider-angle view when the subject is lost in the narrower view, allowing continuous tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a narrow angle of view is used for detailed observation, then observation precision is improved, but the ability to track moving subjects deteriorates
Solution Approach 1:
The electronic binoculars incorporate multiple image capturing units with different angle of view characteristics (wide-angle and narrow-angle). The system can switch between or simultaneously use these different capturing units to adapt to various observation scenarios, making the device universally applicable for both detailed observation and tracking moving subjects.
Solution Approach 2:
The system dynamically switches between different angle of view modes based on the observation situation. When a subject moves out of the narrow angle view, the control unit automatically switches to the wide-angle view to locate the subject again, creating a dynamic adaptation to changing observation conditions.
2Measurement precision
If users temporarily remove their gaze to locate a subject, then subject location accuracy is improved, but continuous observation is interrupted
Solution Approach 1:
The wide-angle image capturing unit continuously monitors the surrounding area and provides feedback information about subject position. When the subject moves out of the narrow angle view, the system uses the wide-angle view to detect the subject's new position and automatically adjusts the display to guide the user back to the subject, eliminating the need to remove gaze.
Solution Approach 2:
The wide-angle image capturing unit acts as an intermediary that detects subject position when the narrow-angle view loses the subject. The control unit uses information from the wide-angle view to automatically adjust the display on the display unit, mediating between the lost subject and the user's line of sight.
3Device complexity
If only a single angle of view is provided, then device complexity is reduced, but adaptability to different observation scenarios deteriorates
Solution Approach 1:
The image capturing system is segmented into multiple independent image capturing units, each with different angle of view characteristics. This segmentation allows the system to handle different observation scenarios independently, with each capturing unit optimized for specific purposes (wide-angle for tracking, narrow-angle for detailed observation).
Solution Approach 2:
By incorporating multiple image capturing units with different angle of view characteristics, the electronic binoculars achieve multi-functionality, capable of handling both wide-area surveillance and detailed close-up observation within a single device.

AI summary
An apparatus includes a first capturing unit configured to obtain a first image; and a second capturing unit configured to obtain a second image having a wider angle of view than an angle of view of the first image. The apparatus controls each of a first display device corresponding to one eye of a user and a second display device corresponding to the other eye of the user to display an image based on the first image or the second image. In a case where no subject exists in the first image, the apparatus causes at least one of the first display device and the second display device to display the second image.
