Solution Overview

Problem

Conventional blur correction technologies fail to account for intended camera movements during programmed photographing, leading to inappropriate image recording data.

Innovation Solution

An information processing apparatus that controls the photographing range of an imaging unit based on a difference between a planned and actual photographing state, using sensor information to correct unintended image blur.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional blur correction technology is used to correct image blur caused by camera shaking, then image quality is improved, but the intended camera movement according to photographing plan is also corrected, resulting in inappropriate image recording data

Engineering Contradiction:

Improveimage qualityVSAvoidintended camera movement information

Core Design Contradiction:

Manufacturing precisionVSLoss of information

Solution Approach 1:

The patent applies local quality by differentiating between intended and unintended camera movements. The control unit selectively applies blur correction only to unintended movements (caused by vibration or deviation) while preserving intended movements (according to photographing plan). This is achieved by comparing actual camera position/attitude with planned values and applying correction only when deviations exceed predetermined thresholds, thus improving image quality without losing intended movement information.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

Instead of applying blur correction universally to all camera movements, the patent inverts the approach by first identifying and excluding intended movements from correction. The control unit determines which movements are intended based on photographing plan comparisons and applies correction only to unintended movements, thereby avoiding the correction of purposeful camera movements while still correcting unwanted blur.

Inventive Principle:

Principle #13The other way round (Inversion)

2Manufacturing precision

If blur correction is applied to all camera movements, then image sharpness is improved, but the photographing plan accuracy is compromised

Engineering Contradiction:

Improveimage sharpnessVSAvoidphotographing plan accuracy

Core Design Contradiction:

Manufacturing precisionVSMeasurement precision

Solution Approach 1:

The patent applies dynamics by making the blur correction process adaptive and conditional. The control unit dynamically determines whether to apply correction based on real-time comparison between actual and planned camera movements. When deviations are within acceptable ranges (intended movements), correction is not applied. When deviations exceed thresholds (unintended movements), correction is applied. This dynamic approach maintains both image sharpness and photographing plan accuracy.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements feedback by continuously comparing actual camera position and attitude with planned values from the photographing plan. The control unit uses sensor information to detect deviations and adjusts correction application accordingly. This feedback mechanism ensures that blur correction is applied only when necessary, maintaining accuracy of intended movements while correcting unwanted deviations.

Inventive Principle:

Principle #23Feedback
