Image Reproducing Apparatus Portrait Landscape Display Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Images taken with a digital camera held vertically and displayed on a 16:9 aspect ratio screen appear significantly small, making them difficult to view.
Innovation Solution
An image reproducing apparatus and method that reads rotation information from the recording medium to generate an image signal, displaying a cutout image when the image is portrait-oriented, allowing for improved visibility by expanding the image within the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portrait-oriented image is displayed on a 16:9 aspect ratio screen, then the image maintains its original orientation, but the image appears significantly small and difficult to view
Solution Approach 1:
The patent divides the display into multiple regions: a central display area for the main image and peripheral display areas for additional image content. When a portrait-oriented image is displayed, the system segments the image data to be displayed in both central and peripheral regions, allowing the image to be viewed at a larger scale without distorting the original aspect ratio.
Solution Approach 2:
The patent utilizes the vertical dimension by displaying portrait-oriented images in a way that exploits the height of the screen. By rotating the image 90 degrees clockwise during display, the system transforms the portrait orientation into a format that fits better within the 16:9 screen dimensions, effectively using spatial transformation to improve visibility.
2Loss of information
If the entire portrait-oriented image is displayed to maintain complete imagery, then the full image is visible, but the image appears small on the screen
Solution Approach 1:
The system segments the portrait-oriented image into multiple portions and displays them in different locations on the screen. The main image is displayed in the central region while additional portions are displayed in peripheral regions, allowing viewers to see the complete image at a larger scale without losing any information.
Solution Approach 2:
The patent implements a nested display structure where multiple image portions are arranged concentrically or in nested patterns. The central display area contains the main image portion while peripheral areas contain additional portions, creating a nested arrangement that maximizes the use of screen space while maintaining complete image information.
3Ease of operation
If a cutout image is displayed to improve visibility, then the image appears larger, but only a part of the original image is shown
Solution Approach 1:
The system segments the portrait-oriented image into multiple portions and distributes them across different display regions. By displaying portions in both central and peripheral areas, the system provides an expanded view that improves visibility while maintaining complete image information through the distributed portions.
Solution Approach 2:
The patent rotates the portrait-oriented image 90 degrees clockwise during display, transforming it into a landscape-oriented display format. This spatial transformation allows the image to be displayed at a larger scale on a 16:9 screen while maintaining completeness through the rotated perspective.

AI summary
When displaying an image taken as portrait-oriented image in a landscape-oriented display area, a cutout image including a partial area of the portrait-oriented image to be displayed is displayed. At that time, a whole image of the port-oriented image which is rotated based on rotation information thereof may be displayed along with the cutout image.
