Hybrid Zoom Image Processing with Supplementary Area Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing devices fail to effectively utilize input image data by not providing means for users to understand information on unused image data while viewing the final output image, particularly in scenarios where optical zooming is combined with digital zooming, leading to difficulties in viewing the movement of subjects outside the displayed area.
Innovation Solution
An image processing device that includes a display, an input part, a specified area setting part, and an additional information display control part to set and display a specified area and additional information on the non-specified area of the input image, updating both in synchronization with the input image updates, allowing users to view supplementary information without changing the digital zoom level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital zooming is used to rapidly change magnification, then operability is improved, but image quality deteriorates compared to optical zooming
Solution Approach 1:
The patent combines optical zooming (for image quality) and digital zooming (for operability) into a hybrid system. The optical device attached to the portable device provides optical magnification while the portable device's processor performs digital zooming on the captured image, merging both approaches to achieve high quality and easy operation simultaneously.
Solution Approach 2:
The patent segments the zooming function into two independent components: optical zooming handled by the attached optical device for quality preservation, and digital zooming handled by the portable device's processor for rapid magnification changes. This segmentation allows each component to optimize its specific function.
2Measurement precision
If optical zooming is used to maintain image quality, then image quality is improved, but operability deteriorates due to manual operation requirements
Solution Approach 1:
The patent merges optical zooming with automated digital zooming control. While optical zooming maintains image quality, the portable device's processor automatically performs digital zooming based on scene analysis, eliminating the need for manual operation and combining the benefits of both approaches.
3Measurement precision
If the specified area is enlarged for detailed viewing, then viewing detail is improved, but information on the entire scene is lost
Solution Approach 1:
The patent adds a temporal dimension to the display by showing a time-series change image that includes both the enlarged specified area and the surrounding non-specified area. This allows users to view detailed information in one time frame while preserving context information in another time frame, eliminating information loss.
Solution Approach 2:
The patent segments the display into two functional areas: a main display showing the enlarged specified area for detailed viewing, and a secondary display showing the non-specified area for context information. This segmentation allows simultaneous access to both detailed and contextual information without compromise.

AI summary
It is an object of the present disclosure to enable displaying information on unused area of an input image while displaying an enlarged image of the input image An image processing device includes a specified area setting part configured to set a specified area in an input image, an additional information setting part configured to set additional information on at least a part of non-specified area which is an area in the input image other than the specified area, and a display control part configured to display the specified area and the additional information on the display as an output image. The user can view the image of the specified area and the additional information at the same time. Therefore, the device can utilize the information of the input image more effectively.
