Solution Overview

Problem

Conventional 3D image processing techniques struggle to maintain consistent display positions of a subject across different viewing conditions, leading to variations that can make the viewing experience less effortless for the viewer.

Innovation Solution

An image processing method and device that adjust the positions of selected 3D perspective images based on a reference position, ensuring the subject appears as if captured from that reference position, regardless of the actual capturing position, thereby aligning the subject's position across different images and viewing conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If images are captured from multiple different perspectives to enable 3D display, then the stereoscopic effect is improved, but the display position of the subject varies across different image pairs

Engineering Contradiction:
Improvestereoscopic effectVSAvoiddisplay position of subject
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action by pre-calculating and storing the positional relationship between the reference position and each capturing position before 3D display. The adjustment amount for each image is determined in advance based on the captured position information, allowing the subject position to be consistently corrected across different image pairs without requiring complex real-time calculations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces a reference position as an intermediary concept to mediate between multiple capturing positions. By defining a reference position and calculating adjustment amounts relative to this reference, the system can harmonize images captured from different perspectives, ensuring the subject appears at a consistent position in the final 3D display regardless of which image pair is selected.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If conventional 3D image processing is used without position adjustment, then the processing complexity is reduced, but the viewing experience becomes less effortless due to subject position variations

Engineering Contradiction:
Improveprocessing complexityVSAvoidviewing experience
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent implements self-service by enabling the image processing system to automatically adjust subject positions using captured position information stored in the system. The adjustment process is performed autonomously by the image processing device without requiring manual intervention or complex external corrections, thereby maintaining simplicity while improving viewing experience.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If additional correction processing like keystone adjustment is applied to maintain subject position, then the position consistency is improved, but the processing time and complexity increase

Engineering Contradiction:
Improvesubject position consistencyVSAvoidprocessing time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent eliminates the need for time-consuming keystone adjustment by performing position adjustment calculations in advance. The adjustment amounts are pre-computed based on the relationship between reference position and capturing positions, allowing rapid application of corrections without requiring complex real-time processing during 3D display operations.

Inventive Principle:
Principle #10Preliminary action

AI summary

Provided is an image processing method in an image processing device for performing image processing on first and second perspective images forming a 3D display image and specified via selection from a group of images obtained by capturing a subject from at least three different perspectives. Adjustment processing is performed on the first perspective image based on a prescribed reference position and a capturing position related to the first perspective image, and shifts the subject in the first perspective image to a position in which the subject would appear if the capturing position were the reference position. Adjustment processing is performed on the second perspective image based on the reference position and a capturing position related to the second perspective image, and shifts the subject in the second perspective image to a position in which the subject would appear if the capturing position were the reference position.
