Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing monitoring camera systems fail to consistently display video images in a desirable layout, especially when switching between different display modes, as previously stored window positions do not always result in an optimal arrangement.

Innovation Solution

A display control apparatus that determines the state of camera operations and controls the display of dialogue boxes based on data indicating whether they should be displayed or not, according to the current display mode, using a determining unit and a control unit to manage the layout information stored in memory.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If window positions are restored to a previously stored layout, then the display mode can be switched efficiently, but the images cannot always be displayed in a desirable layout

Engineering Contradiction:

Improvedisplay mode switching efficiencyVSAvoiddisplay layout quality

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system performs preliminary actions by storing not only window position information but also display mode information together. When a display mode is switched, the system retrieves and applies the layout information that was previously stored for that specific mode, enabling both efficient switching and desirable layout display.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system makes the layout information dynamic by associating it with different display modes. Instead of using a fixed layout for all modes, the layout changes dynamically based on the active display mode, allowing optimal positioning for each mode while maintaining switching efficiency.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple windows and dialogues are displayed simultaneously, then comprehensive camera functions are provided, but the display layout becomes complex and difficult to manage

Engineering Contradiction:

Improvecamera function coverageVSAvoiddisplay layout management

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments the display management by creating separate layout information for each display mode. Each mode has its own predefined window arrangement, allowing multiple windows and dialogues to be displayed comprehensively while simplifying management through mode-specific segmentation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The layout information management system serves multiple functions: it stores window positions, tracks display modes, retrieves appropriate layouts, and applies them automatically. This multi-functional approach handles comprehensive camera functions while simplifying layout management through a universal system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A display control apparatus for controlling a display of a video image photographed by a camera discriminates a state and controls a display of a dialogue box in accordance with data which shows whether or not the dialogue box is displayed in accordance with a display mode for displaying the video image photographed by the camera and with the determined state.
