Image Forming Apparatus Dual-Mode Preview Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming systems experience long page turning times when previewing images with job information, especially when turning multiple pages, due to the time-consuming image processing required for editing and post-processing, leading to inefficient page checking.
Innovation Solution
An image forming apparatus and method that differentiate between first images, which are processed quickly, and second images, which are processed more extensively, allowing for stepwise display to rapidly identify desired pages by switching between them during page turning, reducing unnecessary processing and improving usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image processing based on job information is executed to generate preview images, then the image quality and processing accuracy are improved, but the page turning time becomes excessively long
Solution Approach 1:
The patent segments the image processing into two distinct modes: a first mode that performs basic image generation without job information processing for quick preview, and a second mode that performs comprehensive image processing with job information when needed. This segmentation allows the system to provide rapid page turning while maintaining the option for high-quality processing when required.
Solution Approach 2:
The patent applies partial action by executing only the necessary portion of image processing based on user needs. For quick page turning, only essential image generation is performed without full job information processing. For detailed preview, the complete processing is executed. This partial action approach optimizes the balance between speed and quality.
2Manufacturing precision
If comprehensive image processing is performed for all pages, then the preview image quality is improved, but the time to check multiple pages increases significantly
Solution Approach 1:
The patent implements dynamic processing mode selection that adapts based on user interaction. The system can switch between first mode (quick preview) and second mode (detailed preview) depending on whether the user is performing rapid page turning or examining specific pages in detail. This dynamic approach optimizes both image quality and checking efficiency.
Solution Approach 2:
The patent applies local quality by providing different levels of image processing quality for different usage scenarios. Quick page turning uses simplified processing for speed, while specific page examination uses comprehensive processing for quality. This local differentiation of processing quality ensures efficiency without sacrificing necessary detail where needed.
3Measurement precision
If the system waits for complete image processing before displaying, then the displayed image accuracy is improved, but the user experience during page turning deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-generating basic preview images in the first mode that can be displayed immediately without waiting for complete job information processing. This allows the user to start viewing pages right away, improving user experience, while the option remains to perform complete processing for enhanced accuracy when needed.
Solution Approach 2:
The patent introduces an intermediary processing mode (first mode) that produces intermediate preview images without complete job information processing. These intermediary images provide sufficient quality for quick browsing and page turning, serving as a mediator between rapid display and complete processing accuracy.

AI summary
Disclosed is an image forming apparatus including: a display section for executing display based on image data including a plurality of images; a first image processing section for generating first images respectively corresponding to the images included in the image data, to which an image process based on information of a job is not executed; a second image processing section for generating a second image obtained by executing the image process based on the information of the job to the image data of the first image currently displayed in the display section; and a control section for causing the display section to display the first image corresponding to the image data to which the job is set and to switch the currently displayed first image to the corresponding second image after completing a generation of the second image by the second image processing section.
