Per-Page Scan Settings for File Size and Image Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in achieving both desired file size and quality of scanned documents, particularly when different pages require different scan options, necessitating multiple scan jobs and manual editing, which is cumbersome and inefficient.
Innovation Solution
Implementing a page-specific scan option adjustment system that allows users to adjust scan options and page sizes individually for each page, enabling a single scan job to produce multiple files with tailored settings for optimal file size and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single scan option is applied to all pages, then the scanning process is simple and fast, but the file size and quality cannot be optimized for each specific page
Solution Approach 1:
The patent segments the scanning process by introducing page-specific scan options that can be individually configured for each page. The scanning job is divided into multiple page-level tasks, allowing different scan settings (resolution, color mode, file format) to be applied to different pages based on their specific requirements, thus resolving the contradiction between scanning efficiency and page-specific optimization.
Solution Approach 2:
The patent implements dynamic scan options that can be adjusted on a per-page basis during the scanning process. Instead of using static, uniform settings for all pages, the system allows scan parameters to be dynamically changed for each page, enabling optimal file size and quality for each page while maintaining an automated single-job scanning process.
2Adaptability or versatility
If multiple scan jobs are performed to achieve desired file size and quality for different pages, then page-specific optimization is achieved, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The patent merges multiple individual scan jobs into a single scanning job that processes all pages. By combining the scanning operations while maintaining page-specific scan options, the system achieves the file size and quality optimization that would otherwise require multiple separate scan jobs, thereby eliminating the time loss associated with performing multiple scans and manual editing.
Solution Approach 2:
The patent allows users to pre-configure page-specific scan options for all pages before executing the scan job. This preliminary configuration enables the system to automatically apply the appropriate scan settings to each page during a single scanning operation, eliminating the need for multiple scan jobs and subsequent manual editing, thus saving significant time.
3Adaptability or versatility
If manual editing is performed to achieve desired file size, then quality optimization is possible, but the process is cumbersome and inefficient
Solution Approach 1:
The patent enables the scanning system to automatically control file size and quality for each page through pre-configured scan options, eliminating the need for manual editing. The system serves itself by automatically applying the appropriate scan settings (resolution, compression, format) to each page based on its characteristics, thus achieving file size control without requiring cumbersome manual intervention.
4Adaptability or versatility
If different scan options are applied to different pages, then quality and file size are optimized, but the device complexity increases
Solution Approach 1:
The patent implements a universal scanning job structure that can handle both uniform and page-specific scan options. The system maintains a single, multi-functional scanning job template that automatically adapts to different page requirements, eliminating the need for separate scan jobs for different page types. This universal approach provides scan option flexibility while avoiding the complexity of managing multiple separate scanning processes.
