Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Editing stereoscopic images, which involves flipping or rotating, often results in ghost images and depth inconsistency issues due to the separate left and right view images, making direct application of these operations undesirable.

Innovation Solution

An image processing method that calculates a depth map and generates a new second view image based on the rotated first view image, accounting for the orientation selection, such as a horizontal flip or 180-degree rotation, to maintain depth consistency in stereoscopic images.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If direct flipping or rotation operations are applied to left and right view images, then editing operations can be performed, but ghost images and depth inconsistency problems arise

Engineering Contradiction:

Improveediting operationVSAvoiddepth consistency

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent segments the stereoscopic image into multiple view images (left view image, right view image, and potentially additional views). By processing each view image separately and then recombining them with proper depth map adjustments, the system maintains depth consistency while enabling editing operations. The depth map is also segmented and modified for each view to preserve the 3D effect.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a depth map as an intermediary element between the view images. The depth map stores depth information for each pixel and is used to guide the flipping or rotation operations. By adjusting the depth map according to the orientation selection and generating new view images based on both the original views and the modified depth map, the system prevents ghost images and maintains depth consistency.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If separate processing of left and right view images is performed, then editing flexibility is achieved, but ghost images occur

Engineering Contradiction:

Improveediting flexibilityVSAvoidghost images

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent merges the processing of left and right view images by using a shared depth map that coordinates both views. When flipping or rotating operations are applied, the depth map is adjusted accordingly, and new view images are generated by combining information from both original views with the modified depth map. This coordinated approach ensures that corresponding pixels in left and right views maintain consistent depth relationships, preventing ghost images while preserving editing flexibility.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Various embodiments are disclosed for modifying stereoscopic images. One embodiment is a method implemented in an image processing device for modifying stereoscopic images. The method comprises retrieving, by an image processing device, a stereoscopic image having at least a first view image and a second view image and retrieving an orientation selection relating to the stereoscopic image, the orientation selection comprising a selection other than one of: a horizontal flip selection and a 180 degree rotation selection. The method further comprises calculating a depth map according to at least part of the stereoscopic image, rotating the first view image based on the orientation selection to obtain a rotated first view image, and generating a new second view image according to the depth map and the rotated first view image.
