Image Processing Device for Pierced Earring Orientation Correction

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Images of pierced earrings captured on flat surfaces often depict the hook part rotated 90 degrees relative to the main body, making them appear unnatural when superimposed on a person's image, causing a strange visual effect.

Innovation Solution

An image processing device that acquires pierced earring and head images, specifies the end direction of the hook part, and outputs the superimposed image with the hook part facing the rear of the head, ensuring a more natural representation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If pierced earrings are photographed with the hook part rotated 90 degrees relative to the main body on a flat table, then the image captures the earring structure clearly, but the superimposed image appears unnatural and causes user discomfort

Engineering Contradiction:

Improveimage accuracyVSAvoiduser discomfort

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent applies inversion by rotating the earring image 90 degrees in the opposite direction from the original photographing orientation. Instead of displaying the earring as captured on the flat table (hook part rotated 90 degrees), the system rotates it to match the natural wearing position where the hook part extends toward the rear of the head, thereby eliminating the unnatural appearance and user discomfort while preserving accurate earring structure representation

Inventive Principle:

Principle #13The other way round (Inversion)

2Shape

If the hook part direction in the earring image does not match the rear direction of the head, then the earring structure is preserved, but the composite image becomes unnatural

Engineering Contradiction:

Improveearring structureVSAvoidcomposite image naturalness

Core Design Contradiction:

ShapeVSStability of the object's composition

Solution Approach 1:

The patent applies dynamics by making the earring image orientation adjustable and adaptive rather than fixed. The system dynamically rotates the earring image based on the detected rear direction of the head in the composite image, allowing the hook part to align with the natural wearing position while preserving the earring's structural integrity and achieving a natural composite image appearance

Inventive Principle:

Principle #15Dynamics

AI summary

An image processing device includes a pierced earring image acquisition unit that acquires a pierced earring image showing a pierced earring including a hook part, a head image acquisition unit that acquires a head image at least including a region where an ear is shown, a pierced earring image specifying unit that specifies an end direction of the hook part in the pierced earring image, a head image specifying unit that specifies a rear of a head in the head image, a superimposition unit that superimposes the pierced earring image onto the head image so that the end direction in the pierced earring image faces to the rear of the head in the head image, and an output unit that outputs the image on which the pierced earring image is superimposed. An image closer to the state where the pierced earring is actually worn in the ear is thereby output.
