Solution Overview

Problem

In the field of electronic camera systems, there is a challenge in ensuring that image data of a specific person is accurately obtained, especially when photographers are remote and need to operate multiple cameras, as existing technologies lack effective measures for identifying and framing subjects correctly without direct human intervention.

Innovation Solution

An electronic camera system that includes a photographing ordering system and a photographing system, where the photographing ordering system records and transmits person identifying data to the photographing system, which then judges whether the subject is the intended person and extracts relevant image data for transmission, allowing for remote and accurate image capture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a photographer operates multiple cameras remotely to photograph subjects from many directions, then the coverage and productivity are improved, but the reliability of correctly identifying and framing the intended subject deteriorates

Engineering Contradiction:
Improvephotographing coverageVSAvoidsubject identification accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system implements feedback by having the slave camera transmit captured image data back to the photographing ordering system, which then feeds back control instructions to adjust the slave camera's photographing range. This closed-loop feedback ensures the slave camera continuously adjusts to maintain accurate framing of the intended subject despite being remotely operated

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces manual mechanical control of multiple cameras with an automated control system. The photographing ordering system automatically determines the intended subject and transmits control instructions to slave cameras, eliminating the need for direct manual operation while maintaining or improving subject identification accuracy through automated image processing and feedback mechanisms

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If the number of frames to be photographed is large, then the completeness of capturing all desired people is improved, but the time consumption for selecting and verifying image data increases

Engineering Contradiction:
Improvephotographing completenessVSAvoiddata selection time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system extracts and transmits only the necessary image data to the photographing ordering system. The slave camera selectively captures and transmits image data that meets the photographing orders, filtering out unnecessary frames before transmission. This extraction approach reduces the total data volume while maintaining completeness of capturing all desired people

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The photographing ordering system performs preliminary actions by pre-determining the intended subject and photographing orders before actual capture. The system pre-processes control instructions and transmits them to slave cameras, enabling automated selection and verification of image data during capture rather than requiring post-capture manual sorting through all frames

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If remote control is used to operate multiple cameras, then the photographer's efficiency is improved, but the ability to ensure accurate framing of the intended subject deteriorates

Engineering Contradiction:
Improvephotographer efficiencyVSAvoidframing accuracy
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The slave camera transmits captured image data and position information back to the photographing ordering system, which then adjusts control instructions to refine the photographing range. This feedback loop enables remote operation while maintaining high framing accuracy through continuous automated adjustment based on actual capture results

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The photographing ordering system serves multiple functions: it determines the intended subject, generates control instructions for slave cameras, receives image data, and automatically adjusts photographing ranges. This multi-functional automated system replaces manual operations while ensuring consistent framing accuracy across multiple remotely operated cameras

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

AI summary

An electronic camera system includes a photographing ordering system and a photographing system. The photographing system includes an image sensor which photographs a subject and generates an image signal; a camera-side communication unit which communicates with the photographing ordering system; a subject judging unit which judges whether or not the subject is the person to be photographed based on the person identifying data when or after the subject is photographed; an image processing unit which generates the image data with the image signal; and a camera-side control unit which extracts the image data of which the person to be photographed has been photographed based on a judged result of the subject judging unit and transmits the extracted image data to the photographing ordering system.
