Image Preview Memory Management via Preliminary Action
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses face challenges in previewing images, especially with document files, which require significant drawing memory, leading to suspended enlargement processes and decreased user convenience due to long wait times and failed previews.
Innovation Solution
An image processing apparatus that generates preview images based on document data, allowing for a controlled display of a screen to initiate the generation of subsequent preview images, preventing decreases in user convenience by managing memory usage and displaying the enlarged preview button only when sufficient memory is available.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the preview enlarging function is implemented to allow users to see details of preview images, then image detail visibility is improved, but drawing memory requirements increase significantly causing process suspension and decreased user convenience
Solution Approach 1:
The system performs preliminary actions by checking drawing memory availability before displaying the enlarged preview button. It calculates required memory in advance, compares it with available memory, and only enables the enlargement function when sufficient memory is guaranteed, preventing process suspension and maintaining user convenience
2Reliability
If the enlargement process is suspended due to insufficient drawing memory, then system stability is maintained, but user convenience decreases due to waiting time and inability to view enlarged preview
Solution Approach 1:
The system applies preliminary anti-action by preventing the enlargement operation from being initiated when memory conditions are insufficient. It calculates memory requirements in advance and disables the enlargement function before the user can trigger it, thereby avoiding process suspension and maintaining both system stability and user convenience
3Adaptability or versatility
If drawing memory capacity is increased to support enlargement of all file types, then preview enlargement capability is improved, but device complexity and cost increase
Solution Approach 1:
The system applies partial action by providing enlargement capability selectively rather than universally. It calculates whether sufficient drawing memory is available for each specific file type and only enables enlargement when memory requirements are met, achieving adaptability without requiring increased hardware capacity or complexity

AI summary
An image processing apparatus which is capable of preventing decrease in user convenience with respect to enlarged display of a previewed image. The image processing apparatus generates preview images based on document data. Based on completion of generation of a first preview image based on the document data, a display device is caused to display a screen through which an instruction to start generation of a second preview image based on the document data can be issued.
