Image Scanning Apparatus Visibility Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users struggle to properly reduce the data size of scanned images while maintaining desired visibility, as existing image processing apparatuses do not account for image visibility when adjusting compression settings.
Innovation Solution
An image scanning apparatus with a visibility adjusting unit that uses a user interface with a slider bar to allow users to specify visibility levels, which are then converted to appropriate resolutions based on predetermined conversion rules, enabling users to achieve desired image quality and data size reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If image resolution is decreased to reduce data size, then data size is reduced, but image visibility is deteriorated
Solution Approach 1:
The patent implements dynamic adjustment of image parameters by providing a slider bar that allows users to interactively adjust resolution and compression settings in real-time. This enables the system to adapt to different user needs for visibility versus data size, rather than using fixed compression parameters. The slider bar dynamically transforms the static compression process into an interactive, adaptable solution.
Solution Approach 2:
The patent changes key parameters (resolution, compression ratio) based on user input through the slider bar. By allowing users to adjust these parameters interactively, the system can optimize the balance between data size reduction and image visibility according to specific user requirements, rather than applying a single fixed parameter set.
2Quantity of substance
If compression is increased to reduce data size, then data size is reduced, but image quality is deteriorated
Solution Approach 1:
The system dynamically adjusts compression settings based on user preferences indicated through slider bar interaction. This allows the compression level to be optimized for each user's specific needs, preventing excessive compression that would degrade image quality while still achieving data size reduction.
Solution Approach 2:
The slider bar provides visual feedback to users about the relationship between compression settings and resulting image quality. Users can see how different compression levels affect the image, allowing them to make informed decisions that maintain acceptable image quality while achieving data size reduction.
3Loss of energy
If resolution is decreased to reduce network traffic, then network traffic is reduced, but user satisfaction is deteriorated
Solution Approach 1:
The patent implements dynamic resolution adjustment through the slider bar, allowing users to optimize the balance between network traffic reduction and image visibility according to their specific needs. This dynamic approach prevents user dissatisfaction by giving them control over the trade-off.
Solution Approach 2:
The system enables users to self-adjust the compression and resolution settings according to their own preferences and requirements. By providing the slider bar interface, users can independently optimize the balance between data size reduction and image quality without requiring technical expertise or manual configuration.

AI summary
A visibility adjusting unit (22) displays on the display device (15a)a user interface to specify a visibility level, detects with the input device (15b) a user operation performed to the user interface such that the user operating specifies a visibility level, determines the visibility level based on the detected user operation, and converts the determined visibility level to a resolution in accordance with a predetermined conversion rule. The scan control unit (21) specifies to the image scanning unit (11) the resolution obtained in the conversion performed by the visibility adjusting unit (22) and causes the image scanning unit (11) to generate image data of the document image, and converts the generated image data to image data of a specified data type.
