Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

When browsing multiple images, page switching can cause the selected image to become absent or displayed at a different position, leading to difficulty in maintaining track of the selection frame, thus affecting operability.

Innovation Solution

A display control apparatus that includes a selection unit, display control unit, change unit, storage unit, and control unit to identify and store the position of a selected image before page switching, ensuring the selection frame is correctly positioned after the change, allowing users to easily recognize the selected image even after page switching.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If page switching is performed during multiple reproducing function, then the user can browse all images by dividing them into pages, but the selected image may become absent or displayed at a different position causing the user to lose track of the selection frame

Engineering Contradiction:

Improveimage browsing capabilityVSAvoidselection tracking

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system stores the position information of the selection frame before page switching occurs. This preliminary recording of position data enables the system to restore the selection frame to its original position after page switching, preventing the user from losing track of the selected image.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides visual feedback by displaying the stored position information of the selection frame after page switching. This feedback mechanism allows the user to quickly locate the selection frame on the new page, maintaining operational continuity and ease of use.

Inventive Principle:

Principle #23Feedback

2Productivity

If the selection frame position changes after page switching, then the display can show different images, but the user experiences difficulty in operating immediately due to losing track of the selection frame

Engineering Contradiction:

Improveimage display efficiencyVSAvoidoperation recovery time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary storage of selection frame position information before page switching. This advance preparation eliminates the need for users to search for the selection frame after page switching, reducing operation recovery time and maintaining productivity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system creates a copy of the selection frame position data and uses it to restore the selection frame after page switching. This copying mechanism ensures that the selection frame appears at the correct position without requiring users to re-select or search, minimizing time loss.

Inventive Principle:

Principle #26Copying

AI summary

When changing a plurality of displayed items to a plurality of other items that are at least partially different, at least one selected item of the plurality of displayed items is identifiably displayed, and its display position is stored. After the plurality of displayed items have been changed to the plurality of other items, an item displayed at the same position as the stored display position of the selected item before the change is identifiably displayed. This improves the operability when simultaneously displaying a plurality of items.
