Mobile Terminal Image Overlay with Object Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals lack the ability to efficiently output and link information associated with captured images, making it inconvenient for users to access and manage image data alongside object-related information.
Innovation Solution
A mobile terminal with a camera and controller that captures images, determines focus on an object, and overlays relevant information on the preview image, allowing users to save images with linked information based on user input, and displays this information in a distinguishable manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a mobile terminal captures images with a camera, then image data can be obtained, but the terminal cannot efficiently output and link information associated with the captured images
Solution Approach 1:
The patent merges image data with object-related information by overlaying the information on the preview image or saved image. The controller overlays object information (such as name, description, or other attributes) directly onto the captured image, creating a combined output that preserves both the visual image and its associated data, thereby resolving the loss of information while maintaining ease of operation.
Solution Approach 2:
The patent uses the display unit as an intermediary to present both the image and object-related information to the user. The display unit serves as a mediator that combines visual information with textual or other form of object information, making it easier for users to access and manage image data alongside its associations without requiring separate operations.
2Loss of information
If the terminal overlays information on the preview image, then image data and object information are linked, but the device complexity increases
Solution Approach 1:
The controller performs multiple functions: capturing images via the camera, recognizing objects, obtaining object-related information, determining focus status, and overlaying information on images. By making the controller multi-functional, the patent avoids adding separate dedicated hardware for each function, thereby managing device complexity while achieving comprehensive image and information linkage.
Solution Approach 2:
The controller obtains object-related information and determines focus status before the actual image capture and processing steps. This preliminary action allows the system to prepare necessary data and decisions in advance, reducing the computational burden during image processing and simplifying the overall controller functionality requirements.
3Ease of operation
If the terminal determines focus status and overlays information, then user convenience is enhanced, but the processing time increases
Solution Approach 1:
The controller determines focus status and obtains object-related information before final image capture and processing. By performing these operations in advance, the system reduces the processing time required during the actual image capture moment, thereby enhancing user convenience without significant time penalty.
Solution Approach 2:
The system periodically checks focus status and updates object information overlay based on continuous or interval-based monitoring during image capture. This periodic action allows the system to maintain user convenience features while managing processing time through efficient timing rather than continuous heavy computation.

AI summary
A mobile terminal includes a display unit, a camera that is configured to capture images, and a controller. The controller is configured to access a preview image that is captured by the camera and that includes an object. The controller is further configured to determine, based on the preview image, whether the camera is focused on the object and a prescribed condition of the object is satisfied. The controller is further configured to output, based on a determination that the camera is focused on the object and the prescribed condition of the object is satisfied, information associated with the object by overlaying the information associated with the object on the preview image.
