Mobile Terminal Image Display Using Focus Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable terminals require users to repeatedly operate zooming and panning keys to view specific areas of images, and they do not adapt the image display format to the features of the captured scene, leading to user inconvenience.
Innovation Solution
A portable terminal and method that extract and display interested areas using focus information, allowing images to be displayed in portrait or landscape format based on the features of the area, with the image controlling unit magnifying and formatting the image accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the captured image is displayed as it is captured, then the image display process is simple, but the user must repeatedly operate zooming and panning keys to view specific areas, increasing operation complexity
Solution Approach 1:
The system performs preliminary analysis of the captured image to identify interested areas (such as faces, objects, or regions of interest) and pre-calculates the optimal display parameters. When the user views the image, the system directly displays the pre-processed interested areas without requiring the user to manually zoom or pan, thus saving time and reducing operation complexity
Solution Approach 2:
The image display system automatically identifies and prioritizes interested areas within the captured image, and autonomously adjusts the display parameters (zoom level, position, format) to present the most relevant content first. This self-service approach eliminates the need for users to manually navigate through the entire image to find important elements
2Adaptability or versatility
If the image is displayed according to the shooting mode, then the display format is consistent with capture settings, but the system cannot adapt to the actual features of the image content, reducing display adaptability
Solution Approach 1:
Instead of applying a uniform display format to the entire image based on shooting mode, the system analyzes different regions of the image and applies appropriate display characteristics to specific interested areas. For example, face regions may be prioritized and displayed with different formatting than landscape backgrounds, allowing the display to adapt to the actual content features rather than just the capture settings
Solution Approach 2:
The system dynamically changes display parameters (such as aspect ratio, zoom level, position, and format) based on the analyzed features of the image content. Rather than being constrained by the original shooting mode parameters, the system adjusts these parameters to optimize the display for the actual subjects and compositions present in the captured image
Data Source
AI summary
A portable terminal and a method for displaying an image using focus information are disclosed. An interested area of the captured subject image can be rapidly displayed on the display. The captured subject image can be displayed on the display, according to the features of an interested area image. At least one interested area is extracted from the captured subject image. When one of the extracted interested areas is selected, image information of the captured subject, which includes focus information of the selected interested area, is generated. When requesting that the captured subject image is displayed, an interested area image of the captured subject image is displayed according to focus information of the generated image information.
