Picture Display Control Device Scroll Lock Grid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable information terminals face difficulties in efficiently searching for multiple pictures due to the limitations of the scroll function on small screens, where selected pictures are often lost from view during the scrolling process, making it hard to manage and display favorite images.
Innovation Solution
A picture display control device and method that generates a picture arrangement screen with frame-based picture display cells, allowing users to designate and lock specific pictures while scrolling, ensuring they remain visible, and includes features for editing such as enlargement, deletion, and movement, with a scroll lock function to maintain the position of designated pictures during scrolling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the scroll function is used to search for multiple pictures on a small display screen, then more pictures can be viewed, but the previously selected picture disappears from view and cannot be always displayed
Solution Approach 1:
The display screen is divided into multiple independent picture display regions. When scrolling through pictures, each picture can be displayed in its own region, allowing users to view multiple pictures simultaneously while maintaining visibility of previously selected pictures. This segmentation enables the screen to function as multiple independent viewing areas.
Solution Approach 2:
The patent transitions from a single linear scroll dimension to a multi-dimensional display arrangement where pictures can be organized in grids or matrices. This allows users to navigate through pictures in multiple directions (horizontal and vertical scrolling) while maintaining a comprehensive view of selected pictures across different display regions.
2Productivity
If the screen is divided into multiple areas to maintain visibility of selected pictures, then picture search efficiency improves, but the screen size limitation of portable devices makes screen division difficult
Solution Approach 1:
The display screen is designed to serve multiple functions: it can display full-screen pictures for detailed viewing, divide into multiple regions for comparing multiple pictures, and provide scrolling capabilities in both horizontal and vertical directions. This multi-functionality allows a single screen to replace what would traditionally require multiple specialized display areas.
Solution Approach 2:
The screen display configuration is made dynamic and adaptable. The system can automatically adjust the number and arrangement of picture display regions based on the current operation context, such as switching between single-picture viewing mode and multi-picture comparison mode, optimizing the use of limited screen space for different user needs.
3Area of stationary object
If a desktop personal computer with a large display unit is used, then screen division function can be used to maintain selected pictures visible, but portable information terminals have small display units making screen division difficult
Solution Approach 1:
The patent changes the display parameters by implementing horizontal scrolling capability in addition to vertical scrolling. This allows the system to effectively expand the usable display area without physically increasing the screen size, enabling desktop-like multi-picture viewing experiences on portable devices by utilizing both horizontal and vertical dimensions for picture arrangement and navigation.

AI summary
A picture display control device includes a screen generation unit, a picture designation acceptance unit, an operation acceptance unit, and a scroll processing unit. The screen generation unit generates a picture arrangement screen on which a plurality of picture display cells in which pictures are disposed frame by frame are arranged in a grid shape. The picture designation acceptance unit accepts designation of a picture. The operation acceptance unit accepts an execution instruction to perform scroll processing of replacing a picture to be disposed on the picture arrangement screen. The scroll processing unit executes the scroll processing for other pictures in the picture arrangement screen in a state where a scroll lock for fixing a disposition position in the picture arrangement screen is set to the picture subjected to the designation operation.
