Solution Overview

Problem

Conventional PTZ camera systems require manual user intervention for setting tracking ranges, imposing a significant operational burden on users, especially when objects not desired to be tracked are included in the tracking range.

Innovation Solution

An information processor with object recognition capabilities automatically sets tracking ranges by identifying and allowing users to select predefined regions within a captured image, reducing the need for manual pan-tilt adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a large number of applications are displayed in a list format, then users can access various applications, but the display screen becomes cluttered and hard to recognize

Engineering Contradiction:
Improveapplication accessibilityVSAvoiddisplay complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the application list into multiple pages, with each page displaying a limited number of applications (e.g., 5-10 apps per page). Users can navigate between pages to access different sets of applications. This segmentation reduces the number of applications visible at once, making the display less cluttered while maintaining access to all applications through pagination.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a temporal dimension to application display by implementing automatic rotation between different application pages at predetermined time intervals. Instead of requiring manual navigation, the system automatically cycles through multiple application pages, allowing users to access different sets of applications over time without manually scrolling or switching pages. This transforms the static single-page display into a dynamic multi-page temporal sequence.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If application icons are made larger for easier recognition, then users can recognize applications more easily, but fewer applications can be displayed on the screen

Engineering Contradiction:
Improveapplication recognitionVSAvoidnumber of displayed applications
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

By dividing the application list into multiple pages with fewer applications per page, the system can afford to use larger icon sizes on each page while still providing access to the complete application set across all pages. The segmentation allows larger icons without sacrificing overall application accessibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The automatic rotation feature adds a temporal dimension, allowing the system to display different sets of applications at different times. This enables larger icon sizes on each displayed page since users can access other applications in subsequent time cycles, effectively trading spatial capacity for temporal accessibility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If the display automatically rotates between application pages, then users can access more applications over time, but the switching between pages consumes time

Engineering Contradiction:
Improveapplication accessibilityVSAvoidpage switching time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system implements periodic automatic rotation between application pages at predetermined time intervals. This periodic action allows the display to cycle through multiple application pages automatically, providing users with access to different sets of applications over time without requiring manual intervention. The predetermined intervals are optimized to balance accessibility with time efficiency.

Inventive Principle:
Principle #19Periodic action
