Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional image distribution systems face the risk of unintended wrong operations affecting crop images being output as PGM output images, potentially leading to broadcast accidents.

Innovation Solution

An electronic device equipped with a control unit that prohibits or restricts setting changes affecting the crop region of an input image upon receiving a tally signal, ensuring that the crop image is not inadvertently switched or modified when it is being output as a PGM image.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the crop function is used to output a crop image as a PGM output image, then the flexibility of image distribution is improved, but the risk of wrong operations affecting the output image increases

Engineering Contradiction:
Improveimage distribution flexibilityVSAvoidoutput image integrity
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system applies preliminary anti-action by detecting when a crop image is being output as a PGM image and proactively preventing setting changes that could affect the crop region. The control unit prohibits operations on the crop image during PGM output, thereby preventing potential wrong operations before they can cause broadcast accidents.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The control unit acts as an intermediary between the crop function and the output interface. It monitors the state of crop images being output and mediates by blocking setting changes that would affect the crop region, thus protecting the integrity of the PGM output image while allowing normal crop operations when not in use.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If setting changes are allowed on crop images during PGM output, then the ease of operation is improved, but the risk of broadcast accidents increases

Engineering Contradiction:
Improvecrop image adjustabilityVSAvoidbroadcast accident risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system applies preliminary anti-action by detecting when a crop image is being output as a PGM image and proactively preventing setting changes that could affect the crop region. The control unit prohibits operations on the crop image during PGM output, thereby preventing potential wrong operations before they can cause broadcast accidents.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The system uses feedback by monitoring the output state of crop images and adjusting the allowed operations accordingly. When a crop image is detected as being output as PGM, the control unit provides feedback by prohibiting setting changes. This dynamic feedback mechanism ensures safety while maintaining operational flexibility when not in PGM output mode.

Inventive Principle:
Principle #23Feedback
