Solution Overview

Problem

Existing remote shooting systems do not allow users to continue or stop moving image recording seamlessly when communication is disconnected, limiting user convenience.

Innovation Solution

The system enables continuous moving image recording during remote shooting, even when communication is disconnected, by allowing users to control and stop the recording through a smart device, using a digital camera with advanced wireless communication protocols and user interface features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system stops moving image recording when communication is disconnected during remote shooting, then communication reliability is maintained, but user convenience deteriorates

Engineering Contradiction:
Improvecommunication reliabilityVSAvoiduser convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary action by storing the moving image data in internal storage medium before communication disconnection occurs. This allows the recording to continue uninterrupted even when communication is lost, as the data is already buffered locally. The user can then review the recorded content after reconnection, maintaining both communication reliability and user convenience.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The internal storage medium acts as an intermediary between the image capturing apparatus and the external storage device. When communication disconnects, the intermediary buffer maintains the data flow by temporarily holding the moving image data, allowing recording to continue without interruption while isolating the system from communication failures.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the system continues moving image recording when communication is disconnected, then user convenience is improved, but loss of information increases

Engineering Contradiction:
Improveuser convenienceVSAvoiddata loss
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system performs preliminary action by continuously buffering moving image data in the internal storage medium before it needs to be transferred. This ensures that even if communication disconnects unexpectedly, no data is lost because the recording buffer is already prepared and can continue writing data locally until reconnection occurs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The internal storage medium provides beforehand cushioning by maintaining a buffer of moving image data that can absorb communication interruptions. This cushioning capacity protects against data loss during disconnection events, as the buffered data serves as a safety margin that allows recording to continue uninterrupted.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Ease of operation

If the display unit remains on during remote shooting, then user convenience is improved, but power consumption increases

Engineering Contradiction:
Improveuser convenienceVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system applies self-service by allowing the user to remotely control the camera through a connected terminal device. The terminal device serves as the primary interface for viewing and controlling the camera, eliminating the need for the camera's display unit to remain on during remote shooting operations, thus reducing power consumption while maintaining user convenience.

Inventive Principle:
Principle #25Self-service

AI summary

An image capturing apparatus (100) capable of being remotely controlled from an external apparatus (200), comprises image capturing means (102), communication means (111) configured to communicate with the external apparatus (200), reception means (101) configured to receive a control instruction from the external apparatus (200) via the communication means (111), and control means (101) configured to control the image capturing apparatus based on the received control instruction. When a connection with the external apparatus (200) by the communication means (111) is disconnected during moving image recording in accordance with remote control from the external apparatus (200), the control means (101) continues the moving image recording and notifies a user whether to stop the moving image recording.
