Grouped Image and Drawing Object Control Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses fail to integrate image data and user-drawn data effectively, leading to separate management and processing challenges.
Innovation Solution
A control method and apparatus that receive an image signal, detect pointer operations on a display surface, generate and display drawing images, and register selected images and drawing images in groups, allowing for unified processing based on user operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image data and drawing data are independently managed, then data integrity is maintained, but integrated processing becomes impossible
Solution Approach 1:
The patent merges image data and drawing data into a unified data structure by introducing a group management mechanism. When a user selects both image data and drawing data, they are registered as a group with a unique group ID, enabling integrated processing while maintaining individual data integrity through the group structure.
Solution Approach 2:
The patent creates a universal data management system that can handle both image data and drawing data through the same interface and processing mechanisms. The group management table and selection processing enable unified operations (copy, move, delete) to work on both data types simultaneously or individually.
2Ease of operation
If separate management of image and drawing data is used, then data structure simplicity is maintained, but user convenience for collective operations decreases
Solution Approach 1:
The patent combines multiple selection operations into a single group selection. When users select both image data and drawing data, the system automatically creates a group relationship, allowing subsequent operations to be applied to both items simultaneously through a single selection action.
Solution Approach 2:
The patent performs preliminary grouping action during the selection phase. Before executing copy, move, or delete operations, the system checks if the selected items form a group and prepares the appropriate processing routine, enabling convenient collective operations without requiring users to manually configure group relationships.

AI summary
A control method for a display apparatus includes displaying a first image based on an input first image signal on a display surface when a first operation on the display surface is detected, displaying a first drawing image corresponding to the first operation on the display surface, when a second operation to select the first image and the first drawing image on the display surface is received, registering the first image and the first drawing image as a first group, and when a third operation to select the first group on the display surface is received, executing first processing corresponding to the third operation.
