Solution Overview

Problem

Existing image capturing apparatuses struggle to automatically align objects with the frame edges to avoid undesirably inclined photographs or videos, especially in varying lighting conditions and quick shooting situations, requiring user intervention or complex post-processing.

Innovation Solution

An image capturing apparatus equipped with an inclination sensor and rotational motion actuator that automatically compensates for angular offsets of the optical sensor device relative to a predetermined axis, ensuring objects are aligned with the frame edges during capture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If graphic markers are provided in the viewfinder and/or display to indicate horizontal and vertical reference axes, then users can align objects with frame edges, but the framed scene becomes poorly visible in intense or weak light conditions and users cannot align objects quickly enough in urgent shooting situations

Engineering Contradiction:
Improvealignment capabilityVSAvoidvisibility in varying light conditions
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces the optical-mechanical viewfinder system with an electronic display system that uses software-based reference indicators. The electronic viewfinder or LCD display shows the framed scene along with graphic markers indicating horizontal and vertical reference axes, allowing users to align objects with frame edges. This electronic approach maintains visibility across varying light conditions unlike purely optical systems.

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

Solution Approach 2:

The patent introduces graphic markers as intermediary visual elements that are superimposed on the framed scene in the electronic display. These markers serve as mediators between the user and the scene, providing clear horizontal and vertical reference axes that help users align objects with frame edges without interfering with the visibility of the actual scene being captured.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If photo retouching or video editing software programs are used to straighten up captured images a posteriori, then inclined images can be corrected, but users need in-depth knowledge of specific software programs and peripheral areas of the image are lost due to cutting

Engineering Contradiction:
Improveimage alignment accuracyVSAvoidpost-processing time and expertise requirement
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent performs the alignment action preliminarily during the image capture process itself, rather than as a post-processing step. The electronic viewfinder or LCD display shows graphic markers and the framed scene simultaneously, allowing users to align objects with frame edges before taking the photograph. This eliminates the need for time-consuming post-processing software operations and prevents loss of image peripheral areas.

Inventive Principle:
Principle #10Preliminary action

3Extent of automation

If the optical sensor device is rotated to compensate for angular offset, then automatic alignment with frame edges is achieved, but the device complexity increases due to additional sensors and actuators

Engineering Contradiction:
Improveautomatic alignment capabilityVSAvoidnumber of components
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent implements a self-service alignment system where the apparatus automatically detects its own angular offset from the horizontal reference axis using an inclination sensor and compensates for it through a rotational actuator. The system monitors and corrects its own alignment status without requiring external intervention, achieving automatic alignment while managing complexity through integrated sensor-actuator coupling.

Inventive Principle:
Principle #25Self-service
