Dual Camera Image Superposition for Telephoto Framing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capturing systems face difficulties in allowing users to easily view and intuitively operate when capturing moving objects, as they struggle to maintain the object within the imaging range due to the narrow angle of view of telephoto lenses, leading to challenges in framing and recognizing the surrounding situation.
Innovation Solution
An image generating apparatus that combines a telephoto image and a wide-angle image, obtained from two cameras with different angles of view, to create a superimposed double image where the wide-angle image is displayed alongside the telephoto image, allowing the user to easily observe both views simultaneously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a telephoto lens is used to capture distant objects, then the magnification and detail of distant objects is improved, but the imaging range and angle of view is narrowed
Solution Approach 1:
The patent divides the imaging function into two separate cameras: one dedicated to telephoto imaging and another dedicated to wide-angle imaging. This segmentation allows each camera to be optimized for its specific function, with the telephoto camera providing detailed magnification of distant objects while the wide-angle camera capturing the surrounding environment, thereby resolving the contradiction between magnification and imaging range.
Solution Approach 2:
The patent creates a multi-functional imaging system where two cameras work together to provide both telephoto and wide-angle capabilities. The telephoto camera captures detailed views of distant objects while the wide-angle camera captures the broader context, enabling the system to serve multiple imaging needs simultaneously and eliminating the limitation of a single lens design.
2Measurement precision
If a telephoto lens with narrow angle of view is used, then the detail of distant objects is improved, but the user has difficulties in recognizing surrounding situation and finding lost objects
Solution Approach 1:
The patent segments the visual information into two separate streams: detailed telephoto views of the main subject and comprehensive wide-angle views of the surrounding environment. This segmentation allows the user to access both levels of detail simultaneously through the viewfinder, improving situational awareness while maintaining focus on distant objects.
Solution Approach 2:
The patent introduces an intermediary display mechanism (viewfinder) that combines and presents both telephoto and wide-angle images to the user. This intermediary interface mediates between the two camera outputs, allowing the user to easily compare and switch between detailed and environmental views, thereby improving ease of operation and object recovery.
3Measurement precision
If the viewfinder displays only telephoto image, then the imaging detail is improved, but the user takes long time to find lost objects and resume imaging
Solution Approach 1:
The patent performs preliminary action by continuously capturing and displaying both telephoto and wide-angle images simultaneously in the viewfinder. This preliminary presentation of environmental context allows the user to quickly locate and track lost objects without needing to search through separate images, significantly reducing the time to resume imaging after losing the subject.
Solution Approach 2:
The patent provides continuous feedback to the user by displaying both telephoto and wide-angle views simultaneously in the viewfinder. This feedback mechanism allows the user to monitor both the detailed subject and environmental context in real-time, enabling rapid recognition and recovery of lost objects while maintaining imaging detail, thereby reducing time loss.

AI summary
An image generating apparatus includes a first generator configured to obtain a first image using a first camera with a first angle of view, a second generator configured to obtain a second image using a second camera with a second angle of view wider than the first angle of view, and a generator configured to generate an observation image using the first image and the second image. The observation image is observable as a double image in which the first image and the second image are superimposed on each other in an area that contains a center of the first image.
