Display Control Device for Duplex Print Preview
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display methods for previewing printed documents with processes like duplex print and saddle-stitch bookbinding require page turning operations, which can be inefficient and time-consuming, especially when dealing with large numbers of pages, as they often necessitate user interaction and prolonged processing times.
Innovation Solution
A display control device that uses animation to showcase page turning processes, where intermediate pages are either omitted or displayed briefly, allowing users to control the display of these pages, and employs a stacking image technique to represent the state of turned pages without requiring explicit user page turning, optimizing the display for duplex print and saddle-stitch bookbinding scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If page turning operations are used to preview all pages, then complete document preview is achieved, but processing time increases significantly
Solution Approach 1:
The patent segments the document preview into three distinct parts: initial pages, intermediate pages, and final pages. This segmentation allows the system to apply different display strategies to different segments - fully displaying initial and final pages while summarizing intermediate pages, thereby balancing information completeness with processing efficiency.
Solution Approach 2:
The patent applies partial action by not displaying every single page in the intermediate section. Instead of showing all intermediate pages individually, the system displays a representative sample or summary, which is sufficient for user understanding without requiring the time-consuming operation of turning through every page.
2Loss of information
If all pages are displayed individually, then detailed view is provided, but user interaction complexity increases
Solution Approach 1:
The patent divides the document into initial pages, intermediate pages, and final pages, applying different display treatments to each segment. This segmentation simplifies user interaction by reducing the number of pages users need to manually navigate through, while still providing detailed views of the most important sections (initial and final pages).
Solution Approach 2:
The patent applies local quality by providing different levels of detail for different parts of the document. Initial and final pages receive full detailed display, while intermediate pages receive summarized display. This localized approach to information presentation optimizes both detail visibility and interaction efficiency by focusing detailed views on sections users are most likely to examine closely.
3Productivity
If intermediate pages are omitted from display, then processing time is reduced, but information completeness may be compromised
Solution Approach 1:
The patent applies partial action by displaying a representative sample of intermediate pages rather than all intermediate pages. This partial display provides sufficient information for users to understand the document's intermediate content without requiring the system to process and display every single intermediate page, thus maintaining productivity while preserving essential information.
Solution Approach 2:
The patent performs preliminary action by providing a summary or representative display of intermediate pages before users request full viewing. This preliminary presentation gives users enough information to determine whether they need to examine specific intermediate pages in detail, reducing unnecessary processing while maintaining information availability when needed.

AI summary
A display control device includes: an obtaining unit that obtains a stacking image formed by stacking plural specific images for specifying respective contents of images recorded on at least one surface of each of plural recording media; and a controller that exerts control so that a process is displayed on a display screen, the process sequentially performing an operation to select one specific image from the plural specific images in the stacking image obtained by the obtaining unit and to change the one specific image to represent a state in which at least a part of a recording medium corresponding to the one specific image is turned, to thereby show at least a part of another specific image hidden behind the one specific image while changing one specific image to be selected.
