Image Magnification Storage for Sequential Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital cameras with small and simple display devices are cumbersome for magnifying and playing back images, requiring repetitive operations to adjust magnification and focus on specific regions, especially in continuous shooting modes, which can lead to missed shutter opportunities due to time-consuming processes.
Innovation Solution
An image sensing apparatus with a designation unit for setting a magnification ratio, a storage unit to store and update this ratio, and a processing unit to apply the stored magnification ratio for sequential image display, allowing users to maintain a consistent magnified region across multiple images, reducing the need for repetitive adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the display device is made small and simple, then the device size is reduced and portability is improved, but the ability to display all pixels and confirm precise image conditions deteriorates
Solution Approach 1:
The image display is divided into a normal display region and a magnified display region. The magnified display region allows selective enlargement of specific areas (such as the center region) to confirm detailed image conditions like focus state, while the normal display region maintains an overview of the entire image. This segmentation enables precise image confirmation on a small display device without requiring the entire image to be displayed at full resolution.
2Measurement precision
If manual adjustment of magnified region position is required for each image, then precise region selection is possible, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The system automatically sets the magnified display region to the center region of the image without requiring manual user input. This preliminary action establishes a default magnified area that is likely to contain the main subject, allowing users to quickly review images without performing repetitive adjustment operations. Users can still manually adjust the magnified region position when needed, but the automatic centering provides a convenient starting point that significantly reduces operation time.
3Measurement precision
If magnification ratio adjustment is performed manually for each image review, then precise control over magnification level is achieved, but the review process becomes time-consuming
Solution Approach 1:
The system automatically determines and applies an appropriate magnification ratio based on the image characteristics and display conditions, without requiring manual user input. The automatic magnification setting provides a suitable enlargement level that allows users to confirm image details efficiently. This self-service approach to magnification control significantly reduces the time required for image review while maintaining adequate precision for focus and composition confirmation.

AI summary
An image sensing apparatus which stores an image signal from an image sensing element and reads out and processes the stored image signal to magnify and display an image on a display device includes a designation unit that designates the magnification ratio of the image to be displayed, a storage unit that stores the magnification ratio designated by the designation unit, and a magnifying processing unit that executes magnifying processing for the stored image signal on the basis of the magnification ratio stored in the storage unit and outputs the image signal to the display device. The magnification ratio stored in the storage unit is updated when a different magnification ratio is designated by the designation unit, and the magnification ratio stored in the storage unit is used for a plurality of images that are sequentially displayed.
