Solution Overview

Problem

Existing image capture systems fail to consider the positional relationship between main cameras and sub-cameras, leading to undesirable reflections in captured images, especially when acquiring ornamental images.

Innovation Solution

An image capture system that includes a determination unit to assess if a sub-camera is within the imaging area of a main camera and an instruction unit to instruct the sub-camera to move outside this area, preventing reflections by determining and adjusting the sub-camera's position based on communication and motion data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual control is used to control all cameras, then the system is simple to operate, but the productivity and responsiveness to moving subjects deteriorates

Engineering Contradiction:
Improvemanual control simplicityVSAvoidimage capturing efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The camera system performs self-service by automatically identifying objects and controlling image capturing without requiring manual intervention. The main camera automatically identifies objects in its imaging area, determines sub-camera positioning, and controls the capturing sequence, enabling the system to serve itself rather than requiring human operators for each capturing decision

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary action by pre-positioning sub-cameras in imaging areas of the main camera before actual object capturing occurs. The main camera first identifies objects, then determines appropriate positions for sub-cameras to capture images of these objects, preparing the system in advance for efficient multi-angle capturing

Inventive Principle:
Principle #10Preliminary action

2Productivity

If sub-cameras are positioned to capture objects, then the productivity and image capturing capability improves, but the sub-camera may be reflected in the main camera's image deteriorating the captured quality

Engineering Contradiction:
Improveimage capturing capabilityVSAvoidcamera reflection in image
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system implements feedback by having the main camera continuously monitor its imaging area to detect the presence of sub-cameras. When a sub-camera is detected within the main camera's imaging area, the system receives feedback about this positioning and automatically adjusts the sub-camera's position to eliminate reflections from captured images

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system applies preliminary anti-action by proactively preventing sub-camera reflections before they occur. The main camera identifies when a sub-camera is positioned within its imaging area and instructs the sub-camera to move to a different position, thereby preventing the harmful reflection effect before it can contaminate the captured image

Inventive Principle:
Principle #9Preliminary anti-action

AI summary

An image capture apparatus includes an image capture unit that captures an image, a communication unit that communicates with another image capture apparatus, a determination unit that determines whether the another image capture apparatus is in an imaging area of the image capture unit, and an instruction unit that instructs the another image capture apparatus to move outside of the imaging area of the image capture unit in a case where the another image capture apparatus is in the imaging area of the image capture unit.
