Display Control Apparatus Magnification Adjustment for Image Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image display systems cause an uncomfortable user experience when switching between images with different aspect ratios, as the enlargement rate is not maintained correctly, leading to inconsistent display sizes and perceived reduction in image size.
Innovation Solution
A display control apparatus that adjusts the magnification of images based on user operations, storing magnification information to ensure that images are displayed at a fit magnification or more when switching, maintaining consistent display sizes across different aspect ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image switching is performed by retaining an enlargement rate from a preceding image, then the enlargement state can be maintained across images, but the display magnification may become smaller than the window fit magnification in images with different aspect ratios, causing the image to appear reduced
Solution Approach 1:
The system dynamically adjusts the enlargement rate based on the aspect ratio of the current image. When switching between images with different aspect ratios, the enlargement rate is automatically modified to ensure the display magnification remains at or above the window fit magnification, preventing the image from appearing reduced while maintaining an enlarged state.
Solution Approach 2:
The system changes the enlargement rate parameter when switching images with different aspect ratios. By detecting the aspect ratio difference and adjusting the enlargement rate accordingly, the system ensures that the display magnification stays within the acceptable range (at or above window fit magnification) while still maintaining an enlarged display state across image transitions.
2Ease of operation
If the enlargement rate is retained across images with different aspect ratios, then the user experience of consistent enlargement is improved, but the display size consistency deteriorates as images appear smaller than the display area
Solution Approach 1:
The system dynamically modifies the enlargement rate based on the target image's aspect ratio to maintain both enlargement consistency and display size consistency. The adjustment ensures that while the enlarged state is preserved across image switches, the display size remains proportional to the display area and does not appear reduced.
Solution Approach 2:
The system adjusts the enlargement rate parameter when detecting aspect ratio differences between consecutive images. This parameter change ensures that the display magnification remains consistent with the display area size while maintaining the enlarged state, preventing images from appearing smaller than they should be.
3Productivity
If image switching is performed without adjusting enlargement rate for aspect ratio differences, then the switching operation is simple and fast, but the display quality deteriorates with inconsistent magnification
Solution Approach 1:
The system performs preliminary detection of the aspect ratio difference between the current and target images before completing the image switch. Based on this detection, the enlargement rate is pre-adjusted to ensure that when the image switching is completed, the display magnification is already at the correct level, maintaining both speed and accuracy.
Solution Approach 2:
The system quickly adjusts the enlargement rate based on aspect ratio detection and completes the image switching operation in a streamlined manner. The magnification adjustment is performed as part of the switching process itself, allowing the system to maintain high switching speed while ensuring accurate magnification for the displayed image.

AI summary
A display control apparatus performs, when an image is switched to another image while remaining enlarged, display not giving an uncomfortable feeling to a user, and performs control, when a first image enlarged and displayed on a display unit is switched into a second image, to zoom and display, out of a display magnification of the second image based on magnification information used in the first image before the switching and stored, and of a fit magnification for making the second image have a size falling within a display area in the display unit to match the display area, the second image at a magnification that is the fit magnification or more when the display magnification based on the magnification information is smaller, and the second image at the display magnification based on the magnification information when the display magnification based on the magnification information is larger.
