Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional imaging devices cannot simultaneously record and display multiple moving images with different magnification factors, limiting the ability to obtain and view a wide range of images with varying zoom levels simultaneously.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple moving images with different magnification factors are recorded, then the ability to obtain and view images with varying zoom levels is improved, but the device complexity increases
Solution Approach 1:
The patent segments the imaging process by dividing the image sensor output into multiple independent moving image data streams, each with different pixel decimation factors. This allows simultaneous capture of wide-angle and zoomed-in views as separate recordable entities, enabling versatile playback options without requiring complex mechanical zoom mechanisms.
Solution Approach 2:
The patent adds a digital processing dimension to resolve the contradiction. Instead of using multiple physical cameras or mechanical zoom systems, it processes the image data digitally by applying different pixel decimation factors to create multiple moving image streams from a single image sensor, thereby achieving multi-magnification capability without increasing hardware complexity.
2Quantity of substance
If multiple pieces of moving image data with different pixel decimation factors are generated, then the quantity of image information is improved, but the loss of time increases
Solution Approach 1:
The patent maintains continuous capture of image data at the image sensor while simultaneously generating multiple moving image data streams with different pixel decimation factors. This continuous processing approach ensures that no image information is lost or captured sequentially, allowing all magnification variants to be generated in real-time from the same incoming data stream.
3Ease of operation
If a single file contains multiple moving images with different definitions, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple moving image data streams with different pixel decimation factors into a single file structure. This consolidation allows users to access wide-angle and zoomed-in views seamlessly during playback without needing to manage separate files, greatly simplifying operation while the system handles the complexity of multi-stream integration in the background.
Solution Approach 2:
The single file structure is designed to be universal, capable of containing and managing multiple moving image data streams with different definitions simultaneously. This multi-functional file format enables the system to store various magnification levels, playback speeds, and view types in one unified container, improving ease of operation without requiring users to understand the underlying complexity.

AI summary
An imaging device includes: an image sensor that captures a subject image at predetermined intervals and outputs image data sequentially; and a file generation unit that records a plurality of pieces of moving image data with different pixel decimation factors from the image data, which are moving image data being generated from the image data as a common source, and information indicating a correspondence relation between a reproduction time of moving image data and moving image data to be reproduced and displayed.
