Solution Overview

Problem

Existing image pickup systems lack the ability to display necessary information on connected display apparatuses tailored to the specific needs of users, such as photographers, video engineers, and switchers, due to variations in display formats and functionalities across different devices, leading to suboptimal operability.

Innovation Solution

A control apparatus that communicates with imaging units to generate display data based on the display ability and operation of connected devices, ensuring information is displayed in formats suitable for each user's role and device capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If display data is generated based on generic display formats, then device complexity is reduced, but information operability and user role-specific needs are not met

Engineering Contradiction:
Improveinformation operabilityVSAvoiddisplay data generation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The display data generation process is made dynamic by automatically adapting to different user roles (photographer, video engineer, switcher) and device types (camera, switcher, monitor). The control apparatus dynamically selects and generates display data based on detected user role and device capabilities, rather than using static generic formats.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes display parameters (information type, format, content) based on user role and device type. Different parameter sets are applied: photographers receive shutter speed/aperture info, video engineers receive focus/exposure info, and switchers receive camera status info. This parameter adaptation resolves the contradiction between customized operability and system complexity.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If display information is customized for each user role and device, then information operability is improved, but system complexity increases

Engineering Contradiction:
Improveuser role-specific operabilityVSAvoidcommunication and control complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The control apparatus performs self-service by automatically detecting user roles and device types, then autonomously generating appropriate display data without manual configuration. The system self-adapts to different scenarios (camera connected to monitor, switcher controlling multiple devices) and automatically adjusts display content, reducing the burden of complex manual setup while maintaining high operability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback loops where the control apparatus receives information about device capabilities and user roles, generates appropriate display data, and transmits it to the display device. This feedback mechanism allows the system to continuously adapt to changing conditions (different devices connected, different users operating) while maintaining optimized display output for each scenario.

Inventive Principle:
Principle #23Feedback

3Ease of manufacture

If generic display formats are used across all devices, then ease of implementation is improved, but display ability matching and information relevance deteriorate

Engineering Contradiction:
Improveimplementation easeVSAvoiddisplay ability matching
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The control apparatus achieves universality by being able to serve multiple user roles (photographer, video engineer, switcher) and multiple device types (camera, switcher, monitor) through a single integrated system. It detects the specific scenario and automatically adapts its display data generation, providing role-specific customized output through a universal platform that handles diverse configurations without requiring separate specialized systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)
