Solution Overview

Problem

Existing receiving apparatuses for capsule endoscopes face challenges in maintaining image quality due to transmission errors in color adjusting information and identification information, which can lead to invalidation of images during the observation period.

Innovation Solution

A receiving apparatus that locks color adjusting information when consecutively repeated or most frequently received during a predetermined period, allowing for stable image processing based on locked color adjusting information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If color adjusting information is continuously updated during transmission, then image processing can adapt to changing conditions, but transmission errors may invalidate images

Engineering Contradiction:

Improveadaptability of image processingVSAvoidreliability of image data

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary actions by locking color adjusting information before transmission errors can occur. The lock controller locks the color adjusting information when identical information is received a predetermined number of times, preparing a reliable baseline before potential transmission issues arise. This allows the system to maintain stable image processing while having a fallback mechanism.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The lock controller monitors received color adjusting information and uses feedback from repeated identical transmissions to determine when to lock the information. When the same color adjusting information is received multiple times, the system feedback confirms reliability and triggers the locking mechanism, preventing future transmission errors from invalidating images.

Inventive Principle:

Principle #23Feedback

2Reliability

If the receiving apparatus uses multiple antennas to receive signals, then signal reception reliability improves, but device complexity increases

Engineering Contradiction:

Improvesignal reception reliabilityVSAvoidcomplexity of receiving apparatus

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Multiple antennas are integrated into a single receiving apparatus that performs multiple functions: signal reception, error detection, and automatic switching. The apparatus universally handles both signal capture and reliability verification, reducing the need for separate systems and managing complexity through functional integration.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The receiving apparatus performs self-service by automatically monitoring signal quality across multiple antennas and switching between them without external intervention. The system self-manages the complexity of multiple antennas through automatic signal comparison and selection, eliminating the need for manual configuration or external control systems.

Inventive Principle:

Principle #25Self-service

3Stability of the object's composition

If the system locks color adjusting information based on repeated transmissions, then image quality stability improves, but response time to actual color changes increases

Engineering Contradiction:

Improvestability of color adjustmentVSAvoidtime delay in color adjustment

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

The system applies partial locking by only locking color adjusting information when received a predetermined number of times, not every transmission. This partial action balances stability and responsiveness: it locks sufficiently to prevent transmission errors from causing invalidation, but not excessively to avoid delaying legitimate color adjustments. The predetermined threshold is calibrated to achieve the optimal balance.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A receiving apparatus includes a receiving unit that receives an image signal, identification information on a transmitting apparatus, and color adjusting information that are radio transmitted from the transmitting apparatus; a lock controller that locks the color adjusting information when the receiving unit receives at least one of consecutively repeated identical color adjusting information and consecutively repeated identical identification information during a predetermined period or when the receiving unit most often receives at least one of the identical color adjusting information or the identical identification information during the predetermined period; and an image processing unit that performs image processing on the received image signal based on the locked color adjusting information.
