Magnified Display Apparatus for Automatic Subject Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small-sized imaging devices, such as mobile phones and digital cameras, face challenges in displaying magnified images of intended subjects due to limited user interface operability and the need for manual selection of magnified display areas, leading to increased time and effort for users to confirm image focus and details.
Innovation Solution
A magnified display apparatus with detection, display area determination, and magnification rate adjustment means automatically detects intended subjects and adjusts the display area and magnification rate, allowing for easy viewing of magnified images without user intervention, applicable to devices with inconvenient operating units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual selection of magnified display area is required, then user can control the display area, but user operation time and effort increase
Solution Approach 1:
The system automatically detects the intended subject and determines the magnified display area without requiring user input. The subject detection unit identifies the subject position, and the magnified display area determination unit automatically selects the appropriate area for magnified display, enabling the system to serve itself rather than requiring manual user selection.
Solution Approach 2:
The system performs preliminary subject detection and magnified display area determination before the user needs to view the magnified image. By pre-identifying the intended subject and pre-calculating the optimal display area, the system eliminates the need for users to manually search and select areas, thereby reducing operation time.
2Weight of moving object
If display unit size is reduced, then device portability improves, but image detail confirmation becomes difficult
Solution Approach 1:
The display is segmented into different functional areas: a normal display area for overall image viewing and a magnified display area for detailed view. By dividing the display function into these segments, the system allows users to access high-resolution details without requiring the entire display unit to be large, thus maintaining device portability while improving detail confirmability.
Solution Approach 2:
The system adds a dimensional aspect by creating a magnified display layer on top of the normal display. This additional dimension of magnification allows users to view details at a higher resolution without physically increasing the display unit size, effectively solving the contradiction between small device size and detailed image viewing.
3Adaptability or versatility
If magnified display area is manually set, then display flexibility is maintained, but operability of small devices deteriorates
Solution Approach 1:
The magnified display area determination unit automatically determines the appropriate display area based on subject detection results, eliminating the need for users to manually set the display area. This self-service approach maintains display flexibility for different subjects while significantly improving the operability of small devices by removing the burden of manual area selection.
Solution Approach 2:
The system dynamically changes the display area parameters (position, size, magnification rate) automatically based on the detected subject. Instead of requiring users to manually adjust these parameters, the system adapts the display parameters autonomously, maintaining flexibility for various imaging scenarios while simplifying user operation on small devices.

AI summary
To provide an apparatus capable of easily displaying a magnified image of a subject intended for by the user. An intended subject such as the face of a man is detected from the image displayed on the screen, and in accordance with the position and size of the intended subject detected, the display area and the magnification rate for magnified display of the intended subject are determined. In accordance with the display area and the magnification rate thus determined, the magnified display is conducted on the screen. In the case where a plurality of intended subjects exist in the image, the intended subjects are classified into a plurality of masses and the magnified display may be conducted for each mass.
